Ingredients
For the Crab Casserole Filling
Lump Crab Meat – Brings sweet, delicate seafood flavor and tender chunks; fresh crab works best for this dish.
Cream Cheese – Creates a rich and velvety base that helps hold the casserole together while baking.
Mayonnaise – Adds smoothness and extra creaminess to the sauce.
Shredded Cheddar Cheese – Delivers bold flavor and a gooey, melted texture.
Shredded Mozzarella Cheese – Provides that irresistible stretch and mild creaminess.
Garlic (minced) – Adds a savory aroma that enhances the seafood.
Dijon Mustard – Brings a subtle tang that balances the richness.
Worcestershire Sauce – Deepens the flavor with a hint of savory umami.
Fresh Parsley (chopped) – Brightens the dish with color and freshness.
Salt and Black Pepper – Adjust to taste for a perfectly balanced flavor.
For the Crispy Topping
Breadcrumbs – Form the crunchy topping that contrasts with the creamy filling.
Melted Butter – Coats the crumbs and helps them turn golden and flavorful during baking.

Method

Step 1: Heat the Oven

Set your oven to 350°F (175°C) so it’s ready when the casserole is assembled. Lightly grease a baking dish with butter or cooking spray to prevent sticking and make serving easier later.

Step 2: Prepare the Creamy Base

Place softened cream cheese and mayonnaise in a mixing bowl. Whisk or beat them together until the mixture becomes smooth and fluffy. This creamy blend forms the foundation of your casserole.

Step 3: Add the Flavorings

Mix in the minced garlic, Dijon mustard, Worcestershire sauce, salt, and pepper. Stir thoroughly so the flavors are evenly distributed throughout the creamy mixture.

Step 4: Add Crab and Cheese

Gently fold in the lump crab meat, about one cup of cheddar cheese, half of the mozzarella, and most of the parsley. Use a light hand to keep the crab chunks intact—those tender bites are the highlight of the dish.

Step 5: Assemble the Dish

Transfer the crab mixture into the prepared baking dish and smooth the top. Sprinkle the remaining cheddar and mozzarella over the surface. In a small bowl, combine breadcrumbs with melted butter, then scatter this mixture over the cheese layer.

Step 6: Bake the Casserole

Place the casserole in the oven and bake for 30–35 minutes until the filling bubbles and the topping turns golden brown. For extra crispiness, broil the casserole for the final minute or two.

Step 7: Rest and Finish

Let the casserole sit for about 5 minutes after removing it from the oven. This helps the filling settle. Garnish with the remaining parsley before serving.

Notes

Expert Tips

Use High-Quality Crab
Fresh lump crab meat produces the best flavor and texture. Imitation crab often becomes chewy when baked.

Mix Gently
Fold the crab into the mixture carefully to keep the chunks whole and tender.

Watch the Baking Time
The casserole should reach 165°F internally. The filling should be creamy but set.

Add Extra Seasoning
A pinch of cayenne or a sprinkle of Old Bay seasoning can give the casserole an extra burst of flavor.

Upgrade the Crunch
Combine traditional breadcrumbs with panko for a topping that’s even crispier.

What to Serve with Baked Crab Casserole

Pair this rich seafood dish with lighter sides for a balanced meal:

Arugula Salad with lemon vinaigrette for freshness
Garlic Bread for scooping up the creamy filling
Roasted Asparagus for a vibrant vegetable side
Creamy Risotto for a luxurious dinner spread
Chilled Chardonnay to complement the delicate crab flavor

Variations & Substitutions

Cheese Twist
Replace part of the cheddar with Gruyère for a nuttier, deeper flavor.

Spicy Version

Seafood Upgrade
Mix in cooked shrimp or lobster to create a luxurious seafood combination.
