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 350°F (175°C). While it warms up, grab your favorite baking dish and give it a good spray with nonstick cooking spray so nothing sticks when you’re ready to serve.

Step 4: Add Cheeses and Seasoning
Remove from heat and mix in cheddar cheese and garlic powder until melted smoothly. Sprinkle Old Bay seasoning into the mixture for that extra kick!
Step 5: Combine Everything
Fold in the cooked shrimp and crab into your cheese sauce until well coated. Pour this heavenly mixture into your prepared baking dish, smoothing the top evenly.
Step 6: Bake to Perfection
Sprinkle Parmesan cheese over the top of your dish and bake in the oven for about twenty-five minutes or until bubbly and golden brown.
