Ingredients:

• 1 pound mixed seafood (shrimp, scallops, mussels, calamari), cleaned and chopped
• 1/2 cup dry white wine
• 1/4 cup olive oil
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1/4 cup all-purpose flour
• 2 cups milk
• 1/4 cup heavy cream
• 1/4 cup grated Parmesan cheese, plus more for topping
• 1/4 cup grated Gruyere cheese, plus more for topping
• 2 tablespoons butter
• 1/4 cup breadcrumbs
• 1 tablespoon chopped fresh parsley
• 1 teaspoon lemon zest
• Salt and freshly ground black pepper to taste
• Pinch of nutmeg
• Optional: 1/4 cup chopped cooked lobster meat for extra richness

Preparing the Seafood:

Before we dive into the creamy, cheesy goodness, let’s get our seafood ready. This step is crucial for ensuring the best flavor and texture in our gratin.

1. Prepare the Seafood: If you’re using frozen seafood, make sure it’s completely thawed. Pat the seafood dry with paper towels. This helps it sear nicely and prevents a watery gratin. Chop the seafood into bite-sized pieces. For shrimp, I like to remove the tails, but that’s totally up to you.
2. Sauté the Aromatics: In a large skillet or sauté pan, heat the olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Don’t rush this step; allowing the onions to soften properly will build a flavorful base.
3. Add Garlic and Cook Briefly: Add the minced garlic to the pan and cook for another minute, until fragrant. Be careful not to burn the garlic, as it can become bitter.
4. Deglaze with White Wine: Pour in the dry white wine and bring to a simmer. Let the wine reduce slightly, about 2-3 minutes, scraping up any browned bits from the bottom of the pan. This adds a wonderful depth of flavor to the sauce.
5. Cook the Seafood: Add the chopped seafood to the pan and cook until it’s just cooked through. This usually takes about 5-7 minutes, depending on the size of the pieces and the type of seafood you’re using. Be careful not to overcook the seafood, as it will become rubbery. The mussels and clams should open; discard any that don’t. If you’re using lobster, add it now.
6. Season and Set Aside: Season the seafood mixture with salt and freshly ground black pepper to taste. Remove the pan from the heat and set aside while you prepare the béchamel sauce.

Making the Béchamel Sauce:

A classic béchamel sauce is the heart of any good gratin. It provides the creamy, rich base that binds all the ingredients together. Don’t be intimidated; it’s easier than you think!

1. Melt the Butter: In a medium saucepan, melt the butter over medium heat.
2. Whisk in the Flour: Add the flour to the melted butter and whisk constantly until a smooth paste forms, called a roux. Cook the roux for about 1-2 minutes, stirring constantly, to cook out the raw flour taste. Be careful not to brown the roux too much.
3. Gradually Add the Milk: Gradually whisk in the milk, a little at a time, making sure to incorporate each addition fully before adding more. This prevents lumps from forming. Continue whisking until the sauce is smooth and thickened.
4. Simmer the Sauce: Bring the sauce to a simmer over low heat, stirring constantly. Simmer for about 5-7 minutes, or until the sauce has thickened to the consistency of heavy cream.
5. Stir in Cream and Cheese: Remove the saucepan from the heat and stir in the heavy cream, Parmesan cheese, and Gruyere cheese. Stir until the cheese is melted and the sauce is smooth and creamy.
6. Season the Sauce: Season the béchamel sauce with salt, freshly ground black pepper, and a pinch of nutmeg. Taste and adjust the seasoning as needed.

Assembling and Baking the Gratin:

Now for the fun part – putting everything together and baking our delicious seafood gratin!

1. Combine Seafood and Sauce: Pour the béchamel sauce over the seafood mixture in the skillet. Gently stir to combine, ensuring that all the seafood is coated in the sauce.
2. Add Lemon Zest and Parsley: Stir in the lemon zest and chopped fresh parsley. These add a bright, fresh flavor that complements the richness of the sauce and seafood.
3. Prepare the Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or cooking spray. I usually use a 9×13 inch baking dish, but any oven-safe dish of similar size will work.
4. Transfer to Baking Dish: Pour the seafood and sauce mixture into the prepared baking dish, spreading it evenly.
5. Prepare the Topping: In a small bowl, combine the breadcrumbs and a little extra grated Parmesan and Gruyere cheese. This adds a nice crispy, cheesy crust to the gratin.
6. Sprinkle with Topping: Sprinkle the breadcrumb mixture evenly over the top of the gratin.
7. Bake the Gratin: Bake in the preheated oven for 20-25 minutes, or until the gratin is bubbly and the topping is golden brown.
8. Let it Rest: Remove the gratin from the oven and let it rest for a few minutes before serving. This allows the sauce to thicken slightly and prevents it from being too runny.

Serving Suggestions:

This seafood gratin is delicious on its own, but it’s also great served with a side of crusty bread for soaking up all that delicious sauce. A simple green salad or steamed vegetables would also make a nice accompaniment.

Tips and Variations:

• Seafood Variations: Feel free to use any combination of seafood you like. Crab meat, lobster, and smoked salmon would all be delicious additions.
• Cheese Variations: Experiment with different types of cheese in the béchamel sauce. Fontina, mozzarella, or provolone would all work well.
• Vegetable Additions: Add some chopped vegetables to the seafood mixture for extra flavor and nutrition. Mushrooms, bell peppers, or spinach would all be great choices.
• Spice it Up: Add a pinch of red pepper flakes to the béchamel sauce for a little bit of heat.
• Make Ahead: You can assemble the gratin ahead of time and store it in the refrigerator for up to 24 hours. Add a few extra minutes to the baking time if baking from cold.

Storage Instructions:

Leftover seafood gratin can be stored in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through.
