What is Shrimp Casserole?

Shrimp casserole is exactly what it sounds like: a hearty, oven-baked dish where shrimp is the star of the show, supported by a creamy, cheesy base and a golden breadcrumb topping. Think of it as mac and cheese’s seafood-loving cousin, but without the noodles and with a whole lot more flavor. In this version, cooked white rice adds substance, and the sour cream and mayo combo brings a tangy creaminess that balances beautifully with the sharp cheddar.

The shrimp get cooked just enough to stay tender without turning rubbery, and the seasoning mix—garlic powder, onion powder, paprika, and a dash of lemon—keeps it zesty. It’s the kind of dish you’d expect to find in a coastal grandma’s kitchen (in the best way), but it fits just as easily into your weeknight dinner rotation. Whether you’re a longtime seafood fan or just dipping your toes in, shrimp casserole is an easy, feel-good dinner that works for all seasons.

Reasons to Try Shrimp Casserole

Let’s be honest, dinner is usually a juggling act—between picky eaters, time limits, and the million other things on your plate. Shrimp casserole helps take the stress out of “what’s for dinner?” without sacrificing taste or satisfaction. First off, it’s quick. You can go from stovetop to table in under 45 minutes. It’s also incredibly adaptable—you can swap in brown rice, toss in some leftover veggies, or even lighten it up with Greek yogurt instead of sour cream.

Plus, this shrimp casserole is a total crowd-pleaser. It’s creamy, cheesy, a little bit fancy (thanks to the shrimp), and just plain comforting. It’s also a great way to serve seafood to kids or those hesitant about fishy flavors—it’s mild, familiar, and baked into something deliciously cozy. Whether you’re looking for a new weeknight staple or something to wow at your next family dinner, this shrimp casserole is the kind of dish you’ll come back to again and again.

Ingredients Needed to Make Shrimp Casserole

• 1 lb large shrimp, peeled and deveined
• 1 cup cooked white rice
• 1 ½ cups shredded cheddar cheese
• 1 cup sour cream
• ½ cup mayonnaise
• 1 tablespoon lemon juice
• 2 teaspoons garlic powder
• 1 teaspoon onion powder
• 1 teaspoon paprika

Instructions to Make Shrimp Casserole

Making a shrimp casserole doesn’t have to be intimidating, especially when you follow this easy step-by-step guide. Whether you’re a first-time casserole maker or a seasoned home cook, these detailed instructions will walk you through each stage with confidence—and maybe even a little excitement. Let’s break it down together.

Step 1: Prep and Cook the Shrimp

Before you start assembling the casserole, let’s handle the shrimp. Make sure you’re using peeled and deveined large shrimp (tail-off is easier for casseroles). If you’re starting with frozen shrimp, thaw them completely and pat them dry with paper towels. Wet shrimp won’t brown well, and they can water down your casserole.

In a large skillet over medium heat, cook the shrimp for 2–3 minutes per side, or until they turn pink and slightly curled. You’re not trying to crisp them up here—just get them cooked through. Keep an eye out: overcooked shrimp can turn rubbery fast. Once they’re done, remove the pan from the heat and set the shrimp aside.

Step 2: Mix the Creamy Sauce

Next up in our step-by-step process: making the creamy base that holds everything together. In a large mixing bowl, whisk together:

• 1 cup sour cream
• ½ cup mayonnaise
• 1 tablespoon lemon juice
• 2 teaspoons garlic powder
• 1 teaspoon onion powder
• 1 teaspoon paprika
• Salt and pepper to taste

This combo gives you a tangy, savory sauce with just enough spice to brighten up the dish. Whisk until the mixture is smooth and well blended—this is your flavor powerhouse, so don’t rush it.

Ingredient swap alert: If you’re running low on sour cream or want a lighter option, feel free to substitute with plain Greek yogurt. We talk more about substitutions like this in our creamy roasted garlic cauliflower soup.

Step 3: Add Rice and Cheese

Now that your sauce is smooth, it’s time to bulk it up with cooked white rice and shredded cheddar cheese. Add:

• 1 cup cooked white rice (make sure it’s fluffy and not soggy)
• 1½ cups shredded cheddar cheese

Fold the rice and cheese gently into the sauce. Stir until the rice is completely coated and the cheese is evenly distributed. The residual warmth from the rice helps the cheese begin to melt, turning this mixture into pure creamy comfort.

Step 4: Combine with Cooked Shrimp

Time to bring everything together! Add the cooked shrimp to your rice and cheese mixture. Gently fold them in to avoid tearing the shrimp or breaking them into bits. You want whole pieces in every bite—not shrimp confetti.

Make sure the shrimp are evenly spread throughout the casserole base. This helps every scoop you serve to feel balanced and satisfying.

Step 5: Assemble in the Baking Dish

Grease a 9×13-inch baking dish with cooking spray or a light brush of butter. Spoon the shrimp and rice mixture into the dish and spread it out evenly. Smooth the top with a spatula to get a nice flat surface for your topping to sit on.

This is also your chance to double-check that everything is evenly layered. A well-spread casserole bakes more evenly and gives you that perfect golden finish on top.

Step 6: Make the Buttery Breadcrumb Topping

In a small bowl, mix:

• 2 tablespoons melted butter
• ½ cup breadcrumbs

Stir them together until the crumbs are fully coated in butter. This creates a crispy, golden topping that contrasts beautifully with the creamy filling.

Sprinkle this mixture evenly over the top of the casserole. Don’t worry if it looks like a lot—it’ll toast up perfectly in the oven and give you that crave-worthy crunch.

Crumb tip: Want a crunchier crust? Use panko instead of regular breadcrumbs or toss in a pinch of parmesan cheese. You can also check out the topping techniques used in our cheesy hamburger potato casserole.

Step 7: Bake to Perfection

Preheat your oven to 350°F (175°C). Slide the casserole into the center rack and bake for 25 to 30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

If the top is browning too fast, you can loosely tent it with foil during the last 10 minutes of baking. You’re aiming for golden and toasty—not charred.

Step 8: Garnish and Serve

Once the casserole is finished baking, let it rest for about 5 minutes. This helps the creamy filling firm up just enough to slice nicely. Sprinkle chopped fresh parsley on top for a pop of color and freshness. It’s optional—but worth it.

Now grab a serving spoon and dig in! Serve it hot and pair it with a fresh salad, roasted veggies, or even a crusty piece of bread.

What to Serve with Shrimp Casserole

Shrimp casserole is rich, creamy, and comforting—so it pairs beautifully with something light and crisp. A simple green salad with lemon vinaigrette can cut through the richness. Steamed green beans, asparagus, or roasted broccoli also make great sidekicks. If you want to go Southern-style, try a slice of cornbread or some sautéed collard greens. For an extra cozy dinner, serve it alongside our cozy roasted garlic and cauliflower soup or autumn Friendsgiving potluck casserole. And if it’s a special occasion (or just a long Monday), pour yourself a glass of white wine—because you deserve it.

Key Tips for Making Shrimp Casserole

Want your shrimp casserole to come out perfect every time? First, don’t overcook the shrimp. It only needs a couple minutes per side—if it curls up too tightly, it’s gone too far. Use fresh (or thawed frozen) shrimp for the best texture. Second, don’t skimp on seasoning.

The garlic powder, onion powder, and paprika bring balance to the richness of the cheese and cream. Third, get your rice fully cooked before mixing it in—you want soft and fluffy, not crunchy. And finally, don’t skip the breadcrumb topping. It gives a lovely golden crunch that makes every bite feel complete. Want to prep ahead? Make the base mixture and store it in the fridge a day ahead—just top with breadcrumbs before baking.

Storage and Reheating Tips for Shrimp Casserole

Shrimp casserole stores well, which means you can totally make it ahead or save leftovers for later. Let it cool completely, then cover tightly and refrigerate for up to 3 days. For longer storage, portion it into freezer-safe containers and freeze for up to 2 months. To reheat, thaw overnight in the fridge if frozen. Then cover with foil and warm in a 350°F oven for 15–20 minutes. You can also microwave individual servings, but do it in short bursts to avoid rubbery shrimp. Add a splash of broth or milk before reheating to help loosen the creamy sauce.
