Ingredient Breakdown: What Makes This Casserole Shine
Understanding the role of each ingredient helps you appreciate and customize the recipe for your palate.
Shrimp: The Star of the Show
Large shrimp, preferably peeled and deveined, provide a sweet, succulent seafood base. Cooking them briefly preserves their tenderness and prevents toughness. The shrimp’s natural brininess complements the creamy cheese sauce perfectly.
Seasoning: Old Bay and Beyond
Old Bay seasoning is the traditional choice for seafood casseroles, delivering a blend of celery salt, paprika, black pepper, and other spices that highlight coastal flavors. If you prefer, Cajun seasoning or a homemade mix of smoked paprika, garlic powder, and cayenne can work beautifully.
Creaminess: Mayonnaise and Cheese Combo
Mayonnaise adds smooth richness without the heaviness of cream or heavy sauces. It blends seamlessly with shredded mozzarella and sharp cheddar cheese, which melt to create the casserole’s luscious, cheesy body.
Flavor Boosters: Garlic Powder and Black Pepper
Simple spices like garlic powder and black pepper enhance the depth without overpowering the delicate shrimp flavor.
Crunch Factor: Panko Bread Crumbs and Butter
Panko breadcrumbs coated in melted butter create a crunchy, golden crust that contrasts the creamy casserole filling. This topping is a crucial textural element that keeps the dish exciting bite after bite.
Step-by-Step Instructions for Perfect Baked Shrimp Casserole
Follow this guide to achieve the ideal balance of creamy, cheesy, and crunchy textures.
Step 1: Preheat and Prepare
- Preheat your oven to 375°F (190°C).
- Butter a 2½-quart casserole dish thoroughly to prevent sticking and add flavor.
Step 2: Cook the Shrimp Briefly
- Bring a large pot of salted water to a rolling boil. Add 1 tablespoon of salt and 1 teaspoon of Old Bay seasoning.
- Add shrimp and cook just until they turn opaque, about 30 seconds to 1 minute. Avoid overcooking.
- Drain and immediately transfer shrimp to a mixing bowl to cool.
Step 3: Mix the Creamy Base
- To the shrimp, add ½ cup mayonnaise, 1 teaspoon garlic powder, and ½ teaspoon freshly ground black pepper. Stir until shrimp are evenly coated.
- Fold in 1 cup shredded mozzarella and 1 cup sharp cheddar cheese. Freshly shredded cheese melts best.
Step 4: Assemble the Casserole
- Spread the shrimp mixture evenly in the buttered casserole dish.
Step 5: Prepare and Add the Crunchy Topping
- In a small pan or microwave-safe bowl, melt 3 tablespoons butter.
- Stir in 1 cup panko breadcrumbs until coated.
- Evenly sprinkle the buttery panko over the shrimp mixture.
Step 6: Bake and Broil
- Bake uncovered for 13–15 minutes until bubbling and heated through (internal temp ~145°F).
- For a golden crust, broil on high for 1–2 minutes. Watch carefully to prevent burning.
Step 7: Rest and Serve
- Let the casserole rest for 10–15 minutes to let the cheese set and flavors meld.
- Scoop and serve warm.
Expert Tips for Best Results
- Use fresh or properly thawed shrimp: Avoid previously frozen shrimp with ice glaze.
- Don’t skip resting: It helps portions hold their shape.
- Freshly shred cheese: Pre-shredded often contains anti-caking agents that affect melt and texture.
- Add lemon zest or fresh herbs: A teaspoon of lemon zest or some chopped parsley brightens the flavor.
- Make it ahead: Assemble the casserole (without topping) and refrigerate for up to 24 hours. Add topping and bake just before serving.
Delicious Variations to Try
Keep this recipe fresh by experimenting with different ingredients:
- Seafood swap: Use scallops, lump crab meat, or cooked lobster instead of shrimp.
- Veggie add-ins: Fold in sautéed spinach, mushrooms, or diced bell peppers for extra nutrition and flavor.
- Cheese variations: Try gouda, Monterey Jack, or pepper jack cheese for a twist.
- Spice it up: Add cayenne pepper, smoked paprika, or hot sauce for heat.
- Gluten-free option: Use gluten-free breadcrumbs or crushed gluten-free crackers.
- Dairy-free: Substitute vegan mayo and cheese; replace butter with olive oil or vegan butter.
What to Serve with Baked Shrimp Casserole
Pair your casserole with sides that complement its richness and bring balance:

- Garlic bread or crusty baguette: Perfect for mopping up cheesy sauce.
- Lemon rice or herbed couscous: Light grains add a subtle citrusy note.
- Roasted or steamed veggies: Asparagus, broccoli, or green beans for freshness.
- Beverages: Crisp white wine like Sauvignon Blanc, Chardonnay, or a sparkling water with lemon.
