Season the beef back ribs all over with salt, pepper, and olive oil. Then add the BBQ rub seasonings and massage them in as well.
Bake beef back ribs for 3 to 3.5 hours at 275 degrees F, uncovered, meat side down (bone side up), until an internal temperature of 202 - 210 degrees F is measured with a thermometer.
Remove the beef back ribs from the oven but leave it on.
Remove the baked beef back ribs from the tray and discard the foil with the beef juice on it. Replace the beef ribs on the rimmed baking sheet with a new piece of foil, this time with the meat side up.
Brush the meaty parts with barbecue sauce and bake for another 15 minutes. Serve and enjoy.
