Why You’ll Love This Shrimp Casserole
Quick and Convenient
One of the best things about this recipe is how fast it comes together. From start to finish, you’re looking at just 30 to 35 minutes. That means you can have a delicious, homemade meal even on your busiest days.
If you’re cooking for a family or feeding a group, it scales beautifully. You can even prep it ahead of time, making it a go-to for entertaining.
Flavorful and Satisfying
This casserole brings together the perfect trio: shrimp, cheese, and a savory breadcrumb topping. The mayo adds richness without overpowering the dish, while garlic powder and Old Bay Seasoning give it that signature seafood kick. The cheese melts into a gooey, creamy base that wraps around each bite of shrimp.
The contrast between the smooth filling and the crispy top makes every bite exciting.
Protein-Packed and Adaptable
Each serving offers a generous amount of protein thanks to the shrimp and cheese. If you're avoiding gluten, you can easily swap in gluten-free breadcrumbs. Prefer something lighter? Replace the mayo with Greek yogurt and you're good to go.
This dish is also low in carbs, which makes it friendly for many dietary needs.

Ingredients and Substitutions
Full Ingredient List
- 2 lbs large shrimp (21-24 count), peeled and deveined
- 1 tablespoon Old Bay Seasoning
- 1 tablespoon salt (for cooking water)
- ⅔ cup mayonnaise
- ½ teaspoon garlic powder
- ½ teaspoon ground black pepper
- 1 tablespoon butter, plus extra for greasing
- ½ cup panko breadcrumbs
- 4 oz shredded mozzarella cheese
- 4 oz shredded medium cheddar cheese
Ingredient Notes
For the shrimp, fresh is fantastic, but high-quality frozen shrimp work well too. Just make sure to thaw them properly and pat them completely dry before cooking.
When it comes to cheese, shredding your own mozzarella and cheddar from the block gives the best melt and texture. Pre-shredded cheeses can have anti-caking agents that prevent smooth melting.
Use full-fat mayonnaise for the richest flavor. It helps bind the casserole and adds moisture to the dish.
Smart Substitutions
- Mayo alternative: Greek yogurt or sour cream can be used in place of mayo if you want a tangier or lighter flavor.
- Cheese options: Swap in gouda or pepper jack for a twist. Gouda adds smokiness, while pepper jack brings a little heat.
- Breadcrumb options: Crushed Ritz crackers, gluten-free panko, or seasoned Italian breadcrumbs all work depending on your preference.
How to Make Cheesy Shrimp Casserole

Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 375°F. Grease a 2½-quart casserole dish or a deep 10-inch skillet with butter.
- Boil the Shrimp: Fill a large pot with water and bring it to a boil. Add 1 tablespoon of salt and 1 tablespoon of Old Bay Seasoning. Add the shrimp and cook for just 30 seconds. They should be opaque and pink but still tender. Quickly remove them and transfer to a large bowl.
- Dry the Shrimp: Let the shrimp cool for about 10 minutes, then use paper towels to pat dry and remove any excess moisture. This is key to preventing a watery casserole.
- Mix the Filling: Add mayo, garlic powder, and black pepper to the shrimp and toss to coat. Add the shredded cheeses and stir everything together until well combined.
- Assemble the Casserole: Spread the mixture evenly into your prepared dish or skillet.
- Make the Topping: Melt 1 tablespoon of butter in a small bowl. Stir in the breadcrumbs until fully coated. Sprinkle this mixture evenly over the shrimp.
- Bake and Broil: Bake uncovered for 13-15 minutes, or until the center reaches 145°F. Switch to broil for 1 to 2 minutes to brown the topping. Keep a close eye so it doesn’t burn.
- Rest Before Serving: Let the casserole rest for about 15 minutes before serving. This helps the filling set and makes it easier to serve.
Pro Tips and Tricks
Best Practices
- Always pat your shrimp dry before mixing with mayo and cheese. Extra moisture will cause a watery casserole.
- Use freshly grated cheese for the best melt and texture.
- Grease your dish with butter to prevent sticking and to add an extra layer of flavor.
Common Mistakes to Avoid
- Overcooking shrimp: They only need 30 seconds in boiling water. Overcooked shrimp turn rubbery.
- Using too much mayo: Stick to the measurements. Too much can make the casserole greasy.
- Skipping the rest time: It’s tempting to dig in right away, but a short rest lets everything settle and taste even better.
Time-Saving Hacks
- Use pre-peeled and deveined shrimp to cut down on prep time.
- Shred your cheese ahead of time and store it in an airtight container.
- Assemble the filling up to 24 hours ahead and refrigerate it until you're ready to bake.
What to Serve with Shrimp Casserole

Best Side Dishes
This casserole is rich, so it pairs beautifully with lighter sides like:
- Roasted carrots or asparagus
- Steamed green beans or Air Fryer Brussels sprouts
- Caesar salad or a fresh cucumber tomato salad
- Sourdough or focaccia bread to soak up the cheesy goodness
Presentation Tips
Serve the casserole in a deep dish and garnish with a sprinkle of fresh parsley or chopped green onions. Add a lemon wedge on the side for a touch of brightness.
Beverage Pairings
- White Wine: Chardonnay or Pinot Grigio works well
- Sparkling Water: Try with lemon or cucumber for a refreshing sip
- Cocktails: A light Bloody Mary or white sangria are excellent with seafood
Storage and Reheating Tips
How to Store Leftovers
- Store in an airtight container in the fridge for up to 3 days.
- Avoid freezing after baking as shrimp tend to become rubbery when reheated from frozen.
Reheating Instructions
- Reheat in a 325°F oven until hot throughout.
- For a crispy topping, use the broiler for the last 2 minutes or reheat individual portions in the air fryer.

Frequently Asked Questions
Yes. You can prep the shrimp and cheese mixture a day in advance and refrigerate it. Add the breadcrumb topping right before baking for best results.
Absolutely. Just reduce the boiling time to about 20 seconds. Smaller shrimp cook even faster and can become rubbery if overcooked.
This can happen if the shrimp weren’t dried thoroughly or were previously frozen and released moisture during baking. Simply blot the excess with a paper towel.
