Italian seasoning, garlic powder, and salt should be added to a bowl with the shrimp before tossing. Set apart.

Melt the butter over medium heat in a large pan. Add the shrimp in one layer once the butter has melted (but before it starts to brown).

Cook the shrimp for 1-2 minutes on each side, or until they are opaque and pink on both sides.

The shrimp should be taken out of the pan and put in a serving plate (if using).

When adding the lemon juice and capers, if used, let them boil in the pan for approximately a minute.

Sprinkle the shrimp with the melted butter mixture. If using, sprinkle fresh herbs on top of the shrimp before serving.
