Ingredients You’ll Need
This recipe comes together beautifully with a handful of simple, wholesome ingredients that each play a vital role in the final taste and texture. From the seasoning that gives the shrimp a subtle kick, to the cheeses that ooze creamy goodness, every element is essential to create this unforgettable Shrimp Casserole with Cheesy Panko Topping Recipe.
- Large shrimp (2 pounds, peeled and deveined): The star of the dish, tender and juicy when cooked just right.
- Old Bay seasoning (1 tablespoon, plus 1 tablespoon salt): Adds that classic seafood flavor and enhances the shrimp’s natural sweetness.
- Mayonnaise (2/3 cup): Creates a rich, creamy base that binds the shrimp and cheese together.
- Garlic powder (1/2 teaspoon): Adds a subtle depth of savory flavor without overpowering the dish.
- Ground black pepper (1/2 teaspoon): Provides a gentle warmth and balances the creaminess beautifully.
- Butter (1 tablespoon, plus extra for greasing): Essential for a luscious panko topping and to prevent sticking in the casserole dish.
- Panko bread crumbs (1/2 cup): Gives the topping that irresistible crunch and golden color.
- Shredded mozzarella cheese (4 ounces): Adds stretchy, mild creaminess that blends seamlessly into the shrimp mixture.
- Shredded medium cheddar cheese (4 ounces): Brings a sharp, tangy note that cuts through the richness and adds flavor complexity.
How to Make Shrimp Casserole with Cheesy Panko Topping Recipe
Step 1: Preheat and Prep
Start by setting your oven to 375°F (190°C) so it’s nice and hot when you’re ready to bake. Lightly grease a 2 1/2 quart casserole dish with butter—this not only prevents sticking but also adds a subtle buttery flavor that complements the topping perfectly.
Step 2: Cook the Shrimp
Next, bring a large pot of salted water to a rolling boil and add the Old Bay seasoning. This step infuses the shrimp with that classic seafood seasoning right from the start. Add your shrimp and cook just until they turn opaque, which happens quickly—about 30 seconds. Overcooking can make shrimp rubbery, so keep an eye on timing. Once done, drain the shrimp thoroughly and transfer them to a bowl to prepare for the creamy mix.
Step 3: Combine the Ingredients
Into the bowl with shrimp, stir in mayonnaise, garlic powder, and black pepper, coating every piece lovingly. Then fold in the shredded mozzarella and cheddar cheeses. This creamy, cheesy mixture is where the magic happens to give the casserole body, richness, and that melt-in-your-mouth texture that defines this Shrimp Casserole with Cheesy Panko Topping Recipe. Pour the mixture evenly into your prepared casserole dish.
Step 4: Make the Topping
Now, melt butter in a small saucepan and stir in the panko bread crumbs until they’re all coated. This buttery coating is key to achieving the crispy, golden crust that makes this dish truly crave-worthy. Scatter the panko mixture evenly over the shrimp and cheese filling for that perfect finishing touch.
Step 5: Bake and Broil
Bake your casserole uncovered for about 13 to 15 minutes or until the center reaches 145°F, ensuring the shrimp are perfectly cooked and the cheese is bubbling. For an extra special crunch and beautiful golden brown top, switch your oven to broil for 1 to 2 minutes—watch closely so it doesn’t burn! Then, allow the casserole to rest for 15 minutes before serving, letting those flavors meld together beautifully.
How to Serve Shrimp Casserole with Cheesy Panko Topping Recipe

Garnishes
A sprinkle of freshly chopped parsley or green onions adds a vibrant pop of color that brightens the plate and freshens the rich flavors. For a touch of elegance, a wedge of lemon on the side lets guests add a zesty citrus burst that perfectly complements the shrimp’s sweetness.
Side Dishes
This Shrimp Casserole with Cheesy Panko Topping Recipe pairs wonderfully with light, fresh sides. Think a crisp garden salad tossed with tangy vinaigrette, roasted asparagus for a bit of earthiness, or even simple garlic bread to soak up any cheesy goodness left on your plate. Each side balances the rich casserole beautifully.
Creative Ways to Present
Serve this casserole in individual ramekins for a charming, personalized touch at dinner parties. Alternatively, place the baked casserole on a rustic wooden board with a few lemon wedges and fresh herbs scattered around for an inviting centerpiece that will get everyone excited to dig in.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover shrimp casserole tightly with plastic wrap or transfer to an airtight container. Stored in the refrigerator, it stays fresh for 3 to 4 days, making it a fantastic option for weekday lunches or quick dinners.
Freezing
This recipe freezes well if you want to prep in advance. Wrap the unbaked casserole tightly with foil and plastic wrap, then freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge before baking according to the original instructions.
Reheating
Reheat leftovers in a preheated oven at 350°F (175°C) for about 15–20 minutes until warmed throughout. To keep the topping crisp, avoid microwaving as it can soften the panko crust. If using a microwave for convenience, you can quickly refresh the crumb topping under the broiler for a minute or two after reheating.
FAQs
Can I use frozen shrimp for this casserole?
Absolutely! Just make sure to thaw the shrimp completely and pat them dry before cooking to avoid excess moisture, which can affect the casserole’s texture.
Is there a way to make this dish spicier?
Yes! Add a pinch of cayenne pepper or a dash of hot sauce to the shrimp mixture for some heat that won’t overpower the creamy, cheesy flavors.
Can I substitute the panko breadcrumbs with something else?
Sure! Regular breadcrumbs or crushed crackers can work, but panko gives the most satisfying crunch. For a gluten-free option, use gluten-free panko or crushed nuts.
How important is the resting time after baking?
Very important! Resting lets the casserole set and the flavors marry, so you get a more cohesive, delicious bite rather than a runny, loose texture.
Can I make this casserole ahead and bake it later?
Yes! You can assemble the casserole and refrigerate it for up to 24 hours before baking. Just add the panko topping right before baking for the best crunch.

This Shrimp Casserole with Cheesy Panko Topping Recipe is a heartwarming dish that manages to be both comforting and special.

Ingredients
Shrimp and Seasoning
- 2 pounds large shrimp (21–24 count), peeled and deveined
- 1 tablespoon Old Bay seasoning, plus 1 tablespoon salt for cooking water
Mix-in Ingredients
- 2/3 cup mayonnaise
- 1/2 teaspoon garlic powder
- 1/2 teaspoon ground black pepper
- 4 ounces shredded mozzarella cheese
- 4 ounces shredded medium cheddar cheese
Topping
- 1 tablespoon butter, plus more to grease the pan
- 1/2 cup panko bread crumbs
Instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Grease a 2 1/2 quart casserole dish well with butter to prevent sticking and to add flavor.
- Cook shrimp: Bring a large pot of water to a boil, adding 1 tablespoon salt and 1 tablespoon Old Bay seasoning. Add the peeled and deveined shrimp and cook just until they turn opaque, about 30 seconds. Immediately drain and transfer shrimp to a mixing bowl.
- Combine ingredients: To the cooked shrimp, add 2/3 cup mayonnaise, 1/2 teaspoon garlic powder, and 1/2 teaspoon ground black pepper. Stir gently to coat all the shrimp evenly. Then add 4 ounces shredded mozzarella cheese and 4 ounces shredded medium cheddar cheese, stirring again until well combined. Pour this mixture into your prepared casserole dish.
- Make topping: In a small pan, melt 1 tablespoon butter. Stir in 1/2 cup panko bread crumbs until they are evenly coated with butter. Sprinkle this mixture evenly over the shrimp casserole.
- Bake and broil: Place the casserole uncovered in the preheated oven and bake for 13-15 minutes, or until the center temperature reaches 145°F and bubbling. For a golden brown crust, broil the casserole for an additional 1-2 minutes carefully watching to prevent burning.
- Rest and serve: Remove the casserole from the oven and let it rest for 15 minutes. This allows the flavors to settle and the casserole to thicken slightly before serving.
Notes
- Be careful not to overcook the shrimp during boiling since they cook quickly and will also cook further in the oven.
- The resting time after baking helps the casserole hold its shape better when serving.
- You can substitute the medium cheddar with sharp cheddar for a more pronounced cheese flavor.
- For a gluten-free option, use gluten-free bread crumbs instead of panko.
- Leftovers can be refrigerated for up to 2 days and reheated in the oven for best texture.
