How long will it take to thaw a 7 lb prime rib roast in the fridge? That depends on how big the roast is. The larger the roast, the longer it will take to thaw. As with most food items, the general rule is that a particular cut needs to be thawed out before cooking it. Continue reading for accurate time on how long to thaw a 7 lb prime rib roast.
The time needed to thaw a 7lb prime rib roast will be 20 hours. It is recommended that you place the roast in the refrigerator to thaw it. If you need to thaw the roast for a faster amount of time, it can be placed in cold water.
However, If you are thawing a 7lb prime rib roast in the refrigerator, it will take about 5 hours; if you do it with cold water, about 1 hour per pound (it will be submerged completely). So although Prime rib slowly thawed in the refrigerator takes a long time to thaw, it’s safer than thawing in the microwave.
Generally, it’s best to plan on approximately 30 minutes per pound of thawing meat. It is because a large roast will take longer than a smaller roast. It can range from six to sixteen hours, depending on the size of your roast.
How Long Does It Take to Thaw a 7 Pound Rib Roast?
Depending on the method you use, it will take 24 – 48 hours to thaw a 7-pound rib roast. It depends on whether or not the roast is bone-in or not.
Thawing a 7-pound rib roast can take between 24 and 36 hours. If the 7-pound rib roast is wrapped in plastic wrap, it will thaw faster than if you wrap it in aluminum foil or if you unwrapped it.
For example, a frozen rib roast wrapped in plastic wrap will typically be set out on the counter at room temperature for 24 hours. Still, a similar roast wrapped in aluminum foil will usually take 36 hours or longer to thaw.
The rule is that it takes 20 to 30 minutes per pound to cook a rib roast, but you should plan for 20 to 30 minutes more if it’s frozen. Meanwhile, roast a boneless beef rib to medium-rare in about 30 to 35 minutes per pound, or 135 to 145 degrees F internal temperature.
Meanwhile, To safely thaw a roast, place the wrapped piece of meat under cool running water or in the microwave before cooking.
Here is a step-by-step guide on how to defrost a rib roast:
To defrost a rib roast, you’ll need to:
1. Plan ahead. Allow approximately 24 hours of thaw time for every 5 pounds of meat.
2. Leave your meat in its store packaging and place it on a rimmed baking sheet or in a shallow pan.
3. Loosely cover the meat (to maintain proper airflow) with plastic wrap or aluminum foil.
4. Place the meat in your refrigerator until completely defrosted, turning once halfway through thawing.
However, if you don’t have that much time, there is a method of microwaving it, which will reduce the cooking time because of the unevenness caused by the cold spots. Cook and cover it at medium heat (325°) until browned.
Note: The thickness of meat to thaw and your refrigerator temperature also plays a part in determining how long it takes to thaw a roast. It will typically take about four hours for each pound of meat.

How Long to Defrost 5 Lb Rib Roast
Cooking a five-pound rib roast takes between 90 minutes and two hours. To defrost your five-pound rib roast, use the refrigerator.
You can also defrost in the refrigerator overnight (for best results) or defrost in cold water: Submerge the 5 lb rib roast into cold water; Change the water every 30 minutes until defrosted.
To safely thaw a 5-pound rib roast in your refrigerator, allow at least four to six hours per pound of meat. If you have little time, place the roast in its sealed packaging in a large bowl of cold water; let it sit for half an hour before cooking or refrigerating.
However, defrosting a large cut of meat, such as a 5 lb. rib-eye roast, can take a long time and lead to bacterial growth if not handled properly.
Meanwhile, The USDA recommends planning on about 24 hours per 5 pounds of prime rib roast, so it’s important to plan and start the thawing process early. Then, simply leave the roast wrapped in its original packaging and put it on a plate on your countertop to defrost at room temperature.
But once the entire roast has reached 40 degrees, which can take up to several days, you can cook it or put it into the fridge, where it will be good for 4 days before being cooked.
How Long to Defrost a 6 Pound Prime Rib
There are two ways to defrost 6-pound prime rib. The first is to thaw it in the refrigerator. If you’re going to cook it as soon as it’s thawed all the way through, leave the rib roast still wrapped and on the dish it was sitting on when purchased, in the refrigerator overnight, or for about 1-2 days.
And ff you aren’t going to cook it for a few days after thawing, unwrap and tightly wrap it in aluminum foil, then refrigerate. It will allow it to breathe better and not develop any odors or flavors.
Thawing 6-pound prime rib is around 30-35 minutes per pound, so 6 lb at room temperature will take 180 to 210 mins. If the prime rib is defrosting in the fridge, it will take 1-2 days.
Alternatively, to thaw a whole prime rib roast, place it in its original wrapping or a resealable bag on a tray in the refrigerator. A 5-pound roast will take 2 to 2 1/2 days to thaw, while a 12-pound roast may take as long as 4 1/2 to 5 days.
If you thaw roast rib properly, it should be cooked within a day. If you need the roast to thaw faster than in the refrigerator, place it in a vacuum-sealed bag and immerse it in cold water. Replace the water every 30-40 minutes to keep the meat consistently cool, then cook as desired. Cook more roasts at once to take up less room in your fridge.
How Long to Thaw 8 Lb Prime Rib Roast
You can thaw 8-lb. prime rib for two days in the refrigerator. Then, wrap the meat in plastic wrap to prevent moisture loss and keep other foods from contaminating it. To do this:
- Place the roast on a wire rack in a shallow roasting pan in the refrigerator.
- Discard juices if your pan is not leak-proof.
- Allow about 5 hours per pound.
For example, an 8 lb roast would take approximately 40 hours to thaw. After thawing, do not leave prime rib in the refrigerator for over 4 days, or it will lose quality.
Alternatively, an average 8-pound prime rib roast should take around four hours to thaw out at room temperature fully.
According to the USDA, the safe way to thaw meat is in the refrigerator, where it will take 3-5 days for an 8-pound roast. To thaw the meat safely but more quickly, use water placed in a leak-proof package or bag and set under cold running water.
How Long to Thaw a 10 Lb Prime Rib
A 10-pound rib roast will take about 25 hours to thaw. The temperature of the refrigerator should be 40 degrees Fahrenheit. Time may vary due to the refrigerator’s weight, density, and temperature.
And if you need one within 48 hours, it is recommended you purchase a fresh one. If you have plenty of time, you can leave it in your refrigerator for 24-48 hours if well wrapped. You will want to shake it every so often to make sure the liquid inside gets spread around as much as possible. It means that the meat cooks more efficiently and evenly.
Alternatively, it takes 2.5 hours per pound of prime rib in cold water. Allow at least 30 minutes of thawing time per pound in the refrigerator.
Meanwhile, according to the USDA Food Safety and Inspection Service, a 10-lb prime rib roast may take up to 6 days to fully defrost in the fridge. A 2-lb roast, on the other hand, would take 3.5 days to thaw.
When Is the Best Time to Take a Prime Rib Out of the Freezer?
The best time to take a prime rib out of the freezer is about one week before cooking or two days for every five pounds.
For best results, prime rib should be thawed and ready to cook 3 days after it’s removed from the freezer. When you are ready to start thawing your frozen prime rib, place the frozen meat on a tray or board in the refrigerator. Transfer the meat to the refrigerator at least 3 days before you plan to cook it.
Additionally, Protect the meat from any outside contamination by keeping its wrapper on for the first 24 hours. After thawing completely, cook it at 200°F (93°C) for approximately 11 minutes per pound of meat.
Though, when planning to cook a prime rib, the key is thawing the meat properly. A quick thaw of any meat can be dangerous to eat. Most experts recommend refrigerating the prime rib in its original packaging for up to 4 days while it thaws.
However, this method still risks bacterial contamination from possible drippings or punctures of the meat’s packaging. Therefore, more cautious cooks will take an additional step, submerging vacuum-packed meat in water for up to 2 hours to expedite thawing without introducing harmful bacteria.
Can You Cook a Frozen Prime Rib?
You can cook a frozen prime rib, and the best way to cook a frozen prime rib is slow, at a low temperature. Remember that prime rib is prized for its tenderness and flavor, so you’ll want to go low and slow no matter what.
For example, you can thaw and cook the frozen prime rib in an oven. However, the best way to prepare frozen prime rib is to allow it to thaw in the refrigerator at 40 degrees Fahrenheit.
Also, you can cook and thaw your frozen boneless prime rib roast on the same day. That will allow you to get the beef to room temperature, sear it and then slow roast it at the right temperature.
Although, it is unsafe to cook a frozen boneless rib roast because it would cook on the outside before it properly reaches the center. It would help if you safely defrosted your boneless prime rib by allowing it to sit in the refrigerator for two days before roasting.
Meanwhile, if your roast is untrimmed and unseasoned, allow around 1 hour per pound to cook. However, if your prime rib is trimmed and seasoned, it’s about 25% faster at 45 minutes per pound.
Additionally, it is not recommended to cook meat from a frozen state, as it can lower the pan’s temperature and require longer cooking times. When cooking frozen meat in the oven, manage your time and temperature to not over-cook or under-cook your product. Cook meat so that at least one side of the product is touching your hot pan
Can You Freeze a Prime Rib Roast?
You can freeze a prime rib roast – but you should cook it before freezing. Cook your roast by braising or searing the meat before roasting and then finishing it in a slow cooker, which will help seal the juices and help preserve the meat.
It would help if you also froze any leftover cooked prime rib as soon as possible to prevent spoilage. To reheat, place frozen prime rib roast in the oven at 300 degrees F. and heat until the desired temperature is reached.
Additionally, You can safely store a cooked prime rib roast in your freezer for up to four months. After that, you must freeze it immediately after you cook it. However, the best way to keep the roast tasting its freshest is by storing the roast in your refrigerator for up to five days before freezing it. Before freezing a prime rib, check your freezer’s manual to determine its ideal and safe freezing temperature range.
If you have a prime rib roast that is already cooked and freshly made, it can be fine to freeze. Make sure you wrap the roast tightly in aluminum foil and then place it inside a freezer bag before freezing.
Can You Freeze a Prime Rib Roast Before Cooking
You can freeze a prime rib roast before cooking for up to four months if you cook it consistently and avoid undercooking it. Ensure that the internal temperature of the roast is below 40 degrees Fahrenheit. It maintains the highest quality and prevents bacteria from growing.
Wrap the roast tightly in plastic wrap or aluminum foil to freeze it. Then place the roast in a freezer bag, remove as much air as possible and seal the bag. Of course, if you want to save time later on, you can cook prime rib ahead of time and then freeze it.
Although, you’ll lose some quality in your meat. Kindly plan and roast it right before serving on the safe side.
Can You Freeze Standing Rib Roast?
You can freeze standing rib roast, but you may better cook and then freeze it. When you freeze a raw piece of meat, the high water content crystallizes, puncturing your meat’s cells and releasing moisture.
To preserve your standing rib roast, freeze it after being cooked to medium-rare. Then, slice it up, place it in a heavy-duty freezer bag, or vacuum-seal the bag and lay it flat in the freezer.
Alternatively, wrap it tightly with plastic or aluminum foil to prevent freezer burn and consume it for the best flavor within 6 to 9 months. After that, the meat will keep in the freezer indefinitely, though the quality will degrade.
The USDA recommends not freezing any meat longer than 6 months and ideally no more than 3 months for optimal quality. However, this is more for maintaining optimal quality rather than being unsafe beyond this time (for example, dry-aging of beef is done over many months).
How Long Can Prime Rib Be Frozen?
Prime rib can be frozen for up to 12 months, depending on how processed and packaged the roast is. The best way to store prime rib is in a vacuum-sealed package or tightly wrapped in heavy foil and plastic wrap.
Avoid storing the roast in its original package if it was factory-wrapped, as this has a shorter freezer life. Dry air is also an enemy of most meats, so consuming the meat within one year is important.
Meanwhile, Prime rib will keep at room temperature for 8-10 minutes but should not be left out any longer after being thawed.
If you have one that is too big or too much to be used on the day you purchased it, that doesn’t mean that you can’t enjoy it later. By simply freezing prime rib, you get to enjoy the fabulous flavor anytime that you want, without worry. Prime rib will last in a freezer cold for up to a year if frozen properly.
However, there are several things you can do if you want to freeze a prime rib roast. Freezing a raw prime rib roast is a better choice than freezing a cooked one because it will retain its flavor, color, and texture.
How to Cook Frozen Prime Rib
Cooking a prime rib roast from frozen takes longer, but it is safe to thaw the meat. Keep in mind; it’s best to plan ahead and thaw your roast in the refrigerator before cooking it.
The most effective way to get frozen prime rib to cook faster and more evenly is to vacuum-seal it. This method stops the formation of ice crystals and allows them to thaw faster. In addition, the vacuum seal will help you season the meat better by trapping in the flavor. Thawing a prime rib roast is considered a delicate process because of its size.
Here is a step by step guide:
When cooking frozen prime rib, the first step is to allow the beef to thaw before cooking. If you are behind time to thaw the meat completely, you can use it while still slightly frozen. The outer surface of the beef will become cooked while the inside remains frozen.
Remove roast from the freezer and place on a large cookie sheet. Bake at 350 °F for 35 minutes to 40 minutes (according to package instructions). Remove roast from the oven and brush generously with the seasoning mixture. Roast it until internal temperature reaches 130°F for medium-rare or 140°F for medium. Let roast rest before slicing and eating.
A frozen prime rib may take longer to cook than thawed meat, but it becomes tender and juicy after some time in the oven. You can prepare frozen prime rib using a conventional oven, slow cooker, grill, or barbecue.
How Long Can Cooked Prime Rib Sit in Fridge
Cooked prime rib can sit in the fridge is 3-4 days. It assumes you have removed the moisture, and it’s wrapped in foil and covered. If not, you may want to throw it away as it won’t be good after a day or two.
However, leftover meat that has been cooked should also be wrapped to prevent air from getting inside the package, which can help slow down the growth of bacteria.
If you aren’t eating the rest of your prime rib within 5 days, freeze it, and it will safely keep for several months.
How Long Can Ribs Stay in the Fridge After Thawing
Prime rib is a delicious cut of beef. However, it can be expensive and should be treated with extra care to avoid waste. Prime rib can also be a dangerous food to leave out for long periods, so you need to decide how long ribs can stay in the fridge after thawing before eating it.
You can store ribs in the refrigerator for three to five days, but when thawed, the meat should have a gray-reddish color, and this is normal. Never refreeze thawing raw ribs.
Meanwhile, there is no way you can safely thaw ribs in the refrigerator without them starting to spoil. So you are better off putting them in the water while they are still frozen.
How Long Can Uncooked Ribs Stay in the Fridge?
Uncooked ribs will last 3 to 5 days in the fridge, which should be plenty of time to pop them in the oven. After that, uncooked ribs last the least amount of time, with a recommended shelf life of one to two days before cooking.
But if you’re not going to cook them until later, it’s best to freeze them. But when you’re ready to cook the ribs again, leave the plates in the refrigerator overnight.
However, fresh uncooked pork spareribs should be pinkish-red, while fresh uncooked loin back ribs are a darker red with some areas of exposed bone. You can refrigerate cooked ribs for 3 to 4 days.
How Long Is Leftover Prime Rib Good For
Leftover prime rib is good for up to 4 days. However, to maintain optimal freshness, it should be refrigerated. So you will need to refrigerate leftover prime rib within 2 hours of cooking. When refrigerating, wrap the prime rib in plastic wrap or aluminum foil, or seal it in a zip-top bag.
Another way to store it is in an airtight container, but Tupperware will work. However, it’s important to label it with the date to prevent foodborne illness when storing pork.
How to Freeze Uncooked Prime Rib
The best way to freeze uncooked prime rib is to use a vacuum sealer. You will also need cryovac bags. The cryovac bags are what will allow you to suck out all the air from the rib. I like to season my prime rib before putting it in the freezer, but that part is up to you.
So to freeze uncooked prime rib, simply wrap it tightly in several layers of plastic wrap or place it in a resealable freezer bag. First, be sure the meat is completely covered so that the freezer does not make it tough. Then, bury the package in the back of your freezer until ready to thaw, and cook this delicious beef cut for a big meal.
However, once the uncooked prime rib is defrosted, you should keep it in the refrigerator until cooking time. Cook the roast within two days of defrosting. Once defrosted, you must cook the prime rib immediately before refreezing it.
Conclusion
For the result on how long to thaw a 7 lb prime rib roast, you can use several methods. The three main ways include using the refrigerator, the microwave, and the oven. The chosen method will depend on your time constraints and your cooking preferences.
Equipment
- 1 Pan
- 1 Oven
Ingredients
- 2.5 kg Standing rib roast
- 1 onion
- 1 garlic
- 5 sprigs thyme
- 3 sprigs rosemary
- 10 tbsp butter
- 5 garlic cloves minced
- 2 tsp rosemary
- 2 tsp thyme
- 2 tsp salt
- 1 tsp black pepper
- 1/2 cups beef broth
- 1/2 cups dry red wine
- 1 tbsp cornflour
Instructions
- Bring Beef to Room Temperature: Take the beef out of the refrigerator two to three hours prior to cooking (key tip for even cooking). With a paper towel, dry.
- Bake at 240°C/460°F (220°C fan) for 10 minutes. Adapt the shelf so the beef is positioned in the centre of the oven.
- Garlic and herb butter: Combine.
- In a heavy-bottomed oven-safe skillet, combine the herbs, onion, and garlic for the roasting bed (or use a roasting pan).
- 1st Slather: Put a small layer of butter on the beef’s underside (ie the bone side). Butter side down, place the beef on the onion, etc. 2/3 of the butter should be distributed on the top and sides (reserve some for Slather 2).
- Roast for 20 minutes in a hot oven.
- Slather 2: Take off and apply the remaining butter over. Reduce oven temperature to 120 C/250 F (100 C fan).
- Slow roast: Continue to roast for a further 1 1/2 hours, basting with the pan juices every 30 minutes, until the internal temperature reaches 50°C/122°F in the centre (for medium rare, Note 4). Early temperature monitoring is recommended.
- Rest: Place the steak on a plate. Rest for 20 to 30 minutes while loosely covered with foil. It will get hotter indoors, reaching 54 C/129 F. (which is medium rare).
- Serve sauce with sliced beef! Serve with Paris Mash and Garlic Sautéed Spinach for the experience of a high-end steakhouse from the past.
- Place the skillet with the remaining onion and garlic over high heat in the stove. Add wine and beef stock, and quickly cook for 10 minutes, or until the liquid has reduced by about 2/3 to 1 1/2 cups.
- heat setting to medium. Combine 2 tablespoons water and cornmeal. Half the mixture in, then whisk. The sauce will thicken in about a minute. If you want it thicker, add more of the cornflour and water mixture.
- Pour into sauce jug after straining into bowl.
