Maritime Seafood Casserole: A Taste of the East Coast

The aroma of the sea is practically woven into my childhood memories. Every Christmas Eve, no matter how far inland we were, my grandmother would somehow conjure the most incredible seafood casserole. It wasn’t just a meal; it was a fragrant promise of family, warmth, and the salty tang of home. The golden, bubbly topping hid a treasure trove of flaky fish, succulent shrimp, and that creamy, comforting sauce that seemed to hug you from the inside out. This recipe isn’t just a dish; it’s a piece of my heart, and I’m thrilled to share it with you.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 15 minutes
• Servings: 8
• Yield: 1 casserole
• Dietary Type: Pescatarian

Ingredients

• 2 cups water
• 1 cup chopped celery
• 3/4 cup finely chopped onion
• 1/2 lb shrimp, peeled and deveined
• 1/2 lb scallops
• 1 1/2 cups cooked lobster meat, chopped
• 1 1/2 cups cooked crabmeat, flaked
• 3 tablespoons butter
• 3 tablespoons all-purpose flour
• 1 cup light cream
• 1 1/2 cups shredded cheddar cheese, divided
• 1/4 teaspoon salt
• 1/4 teaspoon ground black pepper
• 1/2 cup fresh breadcrumbs (or cracker crumbs)
• 2 tablespoons melted butter

Equipment Needed

• Saucepan
• Large Bowl
• Slotted Spoon
• 3.5 L Casserole Dish
• Measuring cups and spoons

Instructions

1. Prepare the Vegetables: In a saucepan, bring the water to a boil. Add the chopped celery and finely chopped onion. Cook until the vegetables are tender, approximately 6 minutes.
2. Transfer Vegetables: Use a slotted spoon to transfer the cooked celery and onions from the saucepan to a large bowl. Leave the water in the saucepan; you’ll use it for poaching the seafood.
3. Poach the Scallops: In the same saucepan and water, gently poach the scallops over low heat until they are firm and opaque. This should take about 3 minutes. Avoid overcooking, as they can become rubbery.
4. Add Shrimp and Cook: Add the shrimp to the saucepan with the scallops and cook for approximately 4 minutes, or until they turn pink and opaque.
5. Drain and Reserve Liquid: Drain the seafood, being careful to reserve 3/4 cup of the cooking liquid. This liquid is crucial for the sauce’s flavor and consistency. Note: this liquid measurement is based on the original serving size. Increase liquid accordingly if you adjusted the ingredient amounts.
6. Combine Seafood: Place all the cooked seafood – scallops, shrimp, lobster meat, and crabmeat – into the large bowl with the cooked celery and onions.
7. Make the Roux: In a large saucepan, melt the 3 tablespoons of butter over medium heat. Once melted, add the 3 tablespoons of all-purpose flour and cook, stirring constantly with a whisk, for 2 minutes. This process creates a roux, which will thicken the sauce. Be careful not to burn the flour.
8. Create the Cream Sauce: Gradually whisk in the reserved 3/4 cup of the seafood cooking liquid and the 1 cup of light cream into the roux. Continue to cook, whisking constantly, until the sauce thickens. This will take a few minutes. Again, this liquid amount is based on the original serving size. Increase liquid accordingly.
9. Add Cheese and Season: Stir in 1 1/2 cups of shredded cheddar cheese until it is completely melted and the sauce is smooth and creamy. Season with 1/4 teaspoon of salt and 1/4 teaspoon of ground black pepper. Taste and adjust seasoning as needed.
10. Combine Seafood and Sauce: Gently pour the cheese sauce over the seafood and vegetable mixture in the large bowl. Stir gently to combine, ensuring all the seafood is coated in the sauce.
11. Transfer to Casserole Dish: Transfer the seafood mixture into a 3.5 L casserole dish. Spread the mixture evenly in the dish.
12. Prepare the Topping: In a small bowl, make the topping by melting the 2 tablespoons of butter. Stir in the remaining 1 cup of shredded cheddar cheese and the 1/2 cup of fresh breadcrumbs (or cracker crumbs). Mix until well combined.
13. Add Topping and Bake: Sprinkle the breadcrumb topping evenly over the casserole.
14. Bake the Casserole: Bake uncovered in a preheated 325°F (160°C) oven for 35-45 minutes, or until the casserole is bubbly around the edges and the topping is golden brown.
15. Rest and Serve: Let the casserole stand for 5 minutes before serving. This allows the sauce to thicken slightly and prevents it from being too runny.

Expert Tips & Tricks

• Don’t Overcook the Seafood: Overcooked seafood is tough and rubbery. Keep a close eye on the shrimp and scallops while poaching, and remove them from the heat as soon as they turn opaque.
• Make-Ahead Option: You can assemble the casserole ahead of time and refrigerate it for up to 8 hours before baking. Add a few minutes to the baking time if baking from cold.
• Substitute Seafood: Feel free to substitute other types of seafood, such as haddock or salmon, based on your preferences and what’s available. Just make sure to use approximately the same volume of fish as stated in the recipe.
• Adjust the Cheese: For a sharper flavor, use a blend of cheddar and Monterey Jack cheese. You can also add a sprinkle of Parmesan cheese to the topping for extra flavor and browning.
• Breadcrumb Options: Panko breadcrumbs will give a crisper topping than regular breadcrumbs. You can also use crushed crackers, such as Ritz crackers or saltines, for a different texture and flavor.

Serving & Storage Suggestions

Serve the Maritime Seafood Casserole hot, straight from the oven. It’s delicious on its own or served over flaky pastry shells, crepes, or even toast. A simple green salad makes a refreshing side dish.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals, stirring occasionally. The casserole can also be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.
