How to Make Shrimp and Crab Au Gratin – Seafood Main Dish
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat The Oven
Preheat your oven to 375°F (190°C) while you gather your ingredients. This ensures everything bakes evenly when you’re ready.
Step 2: Prepare The Seafood
In a skillet over medium heat, melt one tablespoon of butter. Add the shrimp and cook until they’re pink and opaque—this usually takes about three minutes. Toss in the crab meat gently so as not to break it up too much, then remove from heat.
Step 3: Make The Roux
In the same skillet, melt two tablespoons of butter over medium heat. Whisk in flour until smooth; cook for about one minute until golden brown. Gradually add heavy cream while whisking continuously—this avoids lumps!
Step 4: Add Cheese And Seasonings
Once your sauce thickens slightly (around five minutes), stir in about one cup of cheddar cheese along with Old Bay seasoning until it’s melted and gooey. Don’t be shy here; taste it! You may want more seasoning based on your palate.
Step 5: Combine Everything
Add your cooked shrimp and crab mixture into the cheesy sauce. Stir until everything is well coated before transferring it into a greased baking dish.
Step 6: Bake And Serve
Sprinkle additional cheese on top (because why not?), then bake in the oven for about twenty minutes or until bubbly and golden on top. Let it cool slightly before serving with some crusty bread or a fresh salad.
Transfer to plates and serve hot! Enjoy each creamy bite as laughter fills the room—because nothing brings people together like good food!
