Baked Seafood Gratin

Follow our step-by-step guide on how to make Baked Seafood Gratin.

1. Step 1

   To start your delicious seafood bake, grab a heavy skillet and melt half a cup of butter over medium heat.

2. Step 2

   Once the butter is bubbling, toss in the chopped onion and green bell pepper.

3. Step 3

   Sauté these vibrant veggies until they’re tender, which should take about five minutes.

4. Step 4

   Next, sprinkle in half a cup of flour and stir it in, cooking for another ten minutes while keeping a close eye on it to prevent any burning.

5. Step 5

   When it’s ready, remove the skillet from the heat and gently fold in the crabmeat, setting this flavorful mixture aside for later.

6. Step 6

   Now, let’s move on to the seafood! In a large Dutch oven, bring four cups of water to a rolling boil.

7. Step 7

   Add in the shrimp, scallops, and flounder, letting them simmer for just three minutes.

8. Step 8

   After that, drain the seafood but don’t toss out that precious cooking liquid—reserve one cup and set the seafood aside.

9. Step 9

   While you’re at it, preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish to ensure nothing sticks.

10. Step 10

    In a heavy saucepan, melt the remaining half cup of butter over low heat.

11. Step 11

    Once melted, whisk in the remaining half cup of flour and cook for about a minute, stirring constantly to keep it smooth.

12. Step 12

    Now, it’s time to create a creamy sauce! Gradually pour in the milk along with the reserved cooking liquid, stirring continuously until the mixture thickens and starts to bubble, which should take around five to seven minutes.

13. Step 13

    Once it’s nice and thick, mix in the Cheddar cheese, vinegar, Worcestershire sauce, salt, pepper, and a dash of hot sauce for that extra kick.

14. Step 14

    Gently fold in the cooked seafood until everything is well combined and coated in that cheesy goodness.

15. Step 15

    Next, take your crabmeat mixture and press it firmly into the bottom of your prepared baking dish to form a delicious crust.

16. Step 16

    Spoon the creamy seafood mixture over the top, and don’t forget to sprinkle some grated Parmesan cheese for that perfect finishing touch.

17. Step 17

    Pop the dish into your preheated oven and bake for about 30 minutes, or until the top is beautifully golden brown.

18. Step 18

    Once it’s out of the oven, serve it up immediately and enjoy the delightful flavors of your homemade seafood bake! This dish is sure to impress your family and friends, making it a perfect centerpiece for any gathering.
