When preparing the shrimp and crab legs, make sure they are thoroughly dried before tossing them with the cajun seasoning and melted butter.

How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover grilled Cajun seafood boil in an oven-safe dish. Cover it with aluminum foil to retain moisture and heat for about 15-20 minutes, or until everything is warmed through.
For a quicker option, use a microwave. Place the seafood boil in a microwave-safe dish. Add a splash of water or melted butter to keep it moist. Cover with a microwave-safe lid or plastic wrap with a few holes poked in it. Heat on medium power for 2-3 minutes, stirring halfway through, until heated evenly.
If you prefer to use the stovetop, heat a large skillet over medium heat. Add a bit of butter or olive oil to the pan. Add the leftover seafood boil and cook, stirring occasionally, for about 5-7 minutes or until everything is heated through.
For an air fryer method, preheat your air fryer to 350°F (175°C). Place the leftovers in the air fryer basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through to ensure even heating.
If you have a steamer, bring water to a boil in the bottom section. Place the leftover seafood boil in the steamer basket, cover, and steam for about 5-10 minutes or until heated through. This method helps retain the moisture and flavor of the seafood and vegetables.
