Crabmeat Casserole Recipe

Ingredients Needed

Here’s everything you’ll need to bring this recipe to life. Be sure to use fresh, high-quality ingredients for the best results.

• 1 pound crabmeat (lump or claw meat, shells removed)
• 1 cup cooked white rice
• 1 cup mayonnaise
• 2 teaspoons Dijon mustard
• 1 teaspoon Worcestershire sauce
• 1 teaspoon Old Bay seasoning
• 1 cup sharp cheddar cheese, shredded
• ¾ cup breadcrumbs
• ½ cup chopped green onions
• ½ cup chopped red bell pepper
• 2 tablespoons unsalted butter, melted
• 1 egg, lightly beaten
• Salt and pepper, to taste
• Lemon wedges (optional, for serving)

Step-by-Step Instructions

1. Prepare the Oven and Baking Dish

Preheat your oven to 350°F (175°C). Grease a 9x9-inch casserole dish with butter or nonstick cooking spray.

2. Mix the Base Ingredients

In a large mixing bowl, combine the crabmeat, rice, mayonnaise, Dijon mustard, Worcestershire sauce, Old Bay seasoning, and shredded cheddar cheese. Mix until all the ingredients are evenly distributed.

3. Add Vegetables and Egg

Fold in the green onions and red bell pepper for added flavor and texture. Add the lightly beaten egg and mix gently to keep the dish light and fluffy.

4. Assemble the Casserole

Transfer the mixture to the prepared casserole dish, spreading it evenly with a spatula.

5. Create the Topping

Mix the breadcrumbs with the melted butter and sprinkle evenly over the casserole. This will create a golden, crunchy topping.

6. Bake to Perfection

Place the casserole in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and the filling is bubbly.

7. Serve and Enjoy!

Remove from the oven and allow the casserole to cool for 5–10 minutes. Serve warm, with a squeeze of fresh lemon for a zesty finish.

Pro Tips for the Perfect Crabmeat Casserole

Here are a few pro tips to elevate your dish to the next level of deliciousness:

• Use Fresh Crabmeat: High-quality crabmeat will make all the difference in the flavor. If using canned crabmeat, drain it thoroughly.
• Cheese Choices: While sharp cheddar is a classic choice, try gruyere or parmesan for a different flavor profile.
• Spice It Up: Add a pinch of cayenne pepper or diced jalapeños for a spicy kick!
• Make it Ahead: Assemble the casserole a day in advance and bake just before serving to save time.

Customization Ideas

Don’t be afraid to make this recipe your own! Here are some variations to try based on your preferences and what you have on hand:

• Vegetable Boost: Add sautéed mushrooms, spinach, or corn for extra nutrition and flavor.
• Protein Twist: Mix in cooked shrimp or scallops for even more seafood goodness.
• Gluten-Free Option: Replace breadcrumbs with gluten-free crumbs or crushed rice crackers.
• Low-Carb Alternative: Swap rice with cauliflower rice for a keto-friendly version.
