How to Make Shrimp and Crab Au Gratin – Seafood Main Dish

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 375°F (190°C). While it’s warming up, grab your favorite baking dish and lightly spray it with nonstick cooking spray.

Step 4: Mix Everything Together

Stir in shredded cheddar cheese into your creamy mixture until melted. Season generously with salt, pepper, paprika, and garlic powder to taste. Finally, fold in your sautéed shrimp and crab gently so they’re coated evenly.

Step 5: Assemble Your Dish

Pour this delightful mixture into your prepared baking dish. Top generously with panko breadcrumbs and an extra sprinkle of cheese if you’re feeling adventurous!

Step 6: Bake Until Golden

Slide your masterpiece into the oven for about 25-30 minutes or until bubbly and golden brown on top.

Transfer to plates and drizzle with sauce for the perfect finishing touch. Enjoy every cheesy bite as you indulge in this culinary delight!
