When you bake shrimp you will want to pre-heat the oven to 450 degrees. Butter a baking dish or sheet pan. Have the shrimp thawed out. You want them around room temperature. If they are cold when you put them in the oven you will have to allow a little more cooking time.
Place the shrimp on the pan or baking dish so they are not touching each other. Using aluminum foil to line the pan makes cleanup a lot easier.
You can baste with melted butter, add a drop of lemon juice or add seasoning. Any or all will work but none are absolutely necessary.
When cooking the shrimp you will have to watch them close so they don’t get over done. A good estimate is 5 minutes for shrimp ½ inch thick. They are done when they turn opaque, but don’t let them get overdone. They will curl up when cooked and will look like the letter C when they are done. If they look like the letter O they will be over-done. Over cooking makes shrimp turn rubbery and tough.
