Shrimp and Crab Au Gratin: A Culinary Embrace

For me, Shrimp and Crab Au Gratin is more than just a dish; it’s a warm hug on a chilly evening. I remember the first time I tasted it was at a small, family-run seafood restaurant nestled along the coast of Maine. The salty air, the gentle clinking of lobster boats, and that first bite of creamy, cheesy seafood – it was pure magic. The memory of that experience still inspires me every time I recreate this comforting classic, adding my own little touches to bring that same sense of warmth and happiness to my table.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 15 minutes
Total Time: 35 minutes
Servings: 6
Dietary Type: Pescatarian

Ingredients

1/2 cup butter (must be real butter, no margarine)
1/3 cup celery, chopped fine
1 cup white onion, chopped fine
1/2 teaspoon dried red pepper flakes
1/3 cup flour
2 egg yolks
1/2 teaspoon salt
8 ounces crabmeat, cooked and flaked
12 ounces shrimp, cooked, shelled, and deveined
1 (12 ounce) can evaporated milk
1/3 cup milk
12 ounces cheddar cheese, grated (use real cheese, not the pre-shredded stuff)

Equipment Needed

Medium frying pan
Small bowl
3-quart casserole dish

Instructions

Begin by melting the butter in a medium frying pan over medium heat. Ensure the pan is large enough to accommodate all the ingredients later.
Add the finely chopped onions and celery to the melted butter. Sauté them until they become soft and translucent, which usually takes about 5-7 minutes. Stir occasionally to prevent burning.
While the vegetables are sautéing, prepare the egg yolk mixture. In a small bowl, lightly beat the egg yolks with the salt and dried red pepper flakes. Set this mixture aside for later use.
Once the onions and celery are softened, sprinkle the flour evenly over the vegetables in the pan. Mix the flour in thoroughly, ensuring there are no lumps. This step creates a roux, which will help thicken the sauce.
Gradually add the evaporated milk to the pan, stirring constantly to ensure the flour mixture thins out smoothly and doesn’t form any clumps. This step is crucial for a creamy sauce.
Next, add the milk, stirring constantly, until it is completely incorporated into the sauce. Continue stirring until the mixture is smooth and has a slightly thickened consistency.
Carefully add the egg yolk mixture to the pan, stirring continuously to prevent the eggs from scrambling. Cook the mixture for approximately 10 minutes, stirring frequently, allowing it to thicken further. The sauce should coat the back of a spoon.
Remove the pan from the heat. Now, it’s time to add the seafood. Gently fold in the cooked and flaked crabmeat and the cooked, shelled, and deveined shrimp. Be careful not to overmix, as this can break up the delicate crabmeat.
Add 8 ounces of the grated cheddar cheese to the mixture, stirring until the cheese is completely melted and incorporated into the sauce. The sauce should be rich, creamy, and cheesy.
Pour the entire mixture into a well-greased 3-quart casserole dish. This will ensure that the au gratin doesn’t stick to the dish during baking.
Sprinkle the remaining 4 ounces of grated cheddar cheese evenly over the top of the casserole. This will create a beautiful, golden-brown crust when baked.
Bake the au gratin uncovered at 375°F (190°C) for approximately 15 minutes, or until the cheese is melted and bubbly. Keep a close eye on it to prevent the cheese from burning.

Expert Tips & Tricks

For an extra layer of flavor, try adding a splash of dry sherry or white wine to the sauce while it’s simmering.
If you prefer a spicier dish, increase the amount of red pepper flakes or add a dash of hot sauce.
To prevent the cheese from burning, you can broil it for the last minute or two, but watch it very carefully!
You can assemble the au gratin ahead of time and store it in the refrigerator for up to 24 hours before baking. Just add a few extra minutes to the baking time.
For a richer flavor, use a combination of cheddar and Gruyère cheese.

Serving & Storage Suggestions

Serve the Shrimp and Crab Au Gratin hot, straight from the oven. It’s delicious on its own or served with crusty bread for dipping. A simple side salad can provide a refreshing contrast to the richness of the dish.

Leftovers should be stored in an airtight container in the refrigerator. They will keep for up to 3 days. To reheat, you can microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. Freezing is not recommended, as the texture of the sauce and seafood may change.
