Notes
Use a rimmed baking sheet to help contain the melted butter. Otherwise, it can easily spill over into your oven.
Line the baking sheet with parchment paper or spray lightly with a nonstick spray.
Toss the shrimp gently to distribute the butter and seasoning. I use my hands but a silicone spatula will also work.
Once added to the shrimp, the butter will begin to solidify. The butter wants to stick to your hands rather than the shrimp, which is quite slippery. Add any remaining butter left in the bowl to the shrimp after it is on the baking sheet.
Shrimp cooks very quickly and is easy to overcook. Cooking time will vary depending on the size of your shrimp and your oven. As soon as the shrimp turns pink, it's done. Mine took 6 minutes.
