How to Make Crab and Shrimp Casserole Recipe
Step 1: Prep and Sauté the Vegetables
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. In a large skillet, melt the butter and gently sauté the chopped onion, bell pepper, celery, and minced garlic until they are softened and fragrant. This foundational step builds the mellow, savory base your casserole needs.
Step 2: Make the Creamy Sauce
Sprinkle in the flour and stir constantly to cook out the raw taste, forming a smooth roux. Gradually whisk in the milk and chicken broth, making sure no lumps remain as the sauce thickens to a luscious, creamy consistency. This velvety mixture is what binds the casserole together and delivers that irresistible, comforting mouthfeel.
Step 3: Season and Add Seafood
Stir in the Old Bay seasoning, plus salt and pepper to taste, infusing the sauce with its signature seafood spice. Then gently fold in the lump crabmeat and peeled, deveined shrimp, being careful to keep the seafood intact so every bite is bursting with flavor and tender texture.
Step 4: Assemble and Bake
Transfer the rich crab and shrimp mixture to your prepared baking dish, spreading it out evenly. Top with a generous layer of shredded cheddar cheese followed by a scattering of breadcrumbs for that perfect golden crust. Bake for 25 to 30 minutes, until the casserole is bubbling hot and the topping is beautifully browned.
Step 5: Garnish and Enjoy
Once out of the oven, sprinkle chopped fresh parsley over the casserole for a vibrant finish that brightens every serving. This is when your Crab and Shrimp Casserole Recipe truly shines, ready to be devoured and enjoyed.

Storing Leftovers
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Keep it chilled and covered well to maintain moisture and flavor until your next decadent serving.

FAQs
Can I use imitation crab for this recipe?
While lump crabmeat adds the best authentic flavor and texture, you can use high-quality imitation crab if needed. Just keep in mind the taste and texture will be milder and less flaky.
What type of shrimp works best in this casserole?
Large shrimp that are peeled and deveined are ideal, as they provide a meaty bite that stands up well during baking without becoming rubbery.
Can I make this casserole gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend and use gluten-free breadcrumbs to keep the casserole safe for gluten-sensitive diets.
Is this recipe spicy?
This casserole has a gentle, savory warmth thanks to the Old Bay seasoning but is not spicy hot. You can always add a pinch of cayenne or hot sauce to amp up the heat if you like.
How long can I bake the casserole in advance before serving?
You can prepare and bake the casserole a few hours ahead, then keep it covered in a warm oven (around 200°F) until ready to serve, ensuring it stays hot and bubbly without drying out.
