How to Make Creamy Shrimp and Rice Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 350°F (175°C). Lightly grease your baking dish with butter or nonstick spray to ensure your creamy masterpiece won’t stick and cleanup stays easy.
Step 2: Sauté the Vegetables
Melt the butter in a large skillet over medium heat and add chopped onion, minced garlic, diced bell pepper, and celery. Let these cook gently for about 5 minutes until they become soft and fragrant—this step builds the flavorful foundation of your casserole.
Step 3: Cook the Shrimp
Add the peeled and deveined shrimp to the hot skillet and cook for 2 to 3 minutes or until they turn a lovely pink. Cooking the shrimp in the vegetable mixture allows their flavor to mingle beautifully before combining with the creamy sauce. Once done, remove the skillet from heat.
Step 4: Mix the Creamy Base
In a large bowl, stir together the cooked rice, shredded cheddar, grated Parmesan, milk, heavy cream, sour cream, and the seasonings including Old Bay, paprika, salt, pepper, thyme, and oregano. All these ingredients combine to create the luscious, flavorful creamy base that makes this dish irresistible.
Step 5: Combine Everything and Transfer
Fold the cooked shrimp and sautéed vegetables into the creamy rice mixture until everything is evenly combined. Pour this mixture into your prepared baking dish, spreading it out evenly for baking.
Step 6: Add a Crunchy Optional Topping
If you love a textural contrast, sprinkle the top with breadcrumbs. This little extra step will yield a crispy, golden crust that adds delightful variety with every bite.
Step 7: Bake to Perfection
Bake in the preheated oven for 25 to 30 minutes, or until the casserole is bubbly and the top turns a beautiful golden brown. This baking step allows the flavors to meld and the cheese to melt into pure perfection.
Step 8: Garnish and Serve
Finish by sprinkling freshly chopped parsley over the top for a burst of color and freshness that brightens the rich casserole beautifully.
How to Serve Creamy Shrimp and Rice Casserole Recipe

Garnishes
Fresh parsley is a classic choice to sprinkle over this casserole right before serving, offering a vibrant green contrast that lifts the dish visually and adds a mild herbal note. For an extra touch, you can add a squeeze of lemon juice to lighten the rich creaminess.
Side Dishes
This casserole pairs wonderfully with simple, crisp sides like a fresh green salad or steamed vegetables such as asparagus or green beans. The lightness and crunch balance out the creamy, indulgent shrimp and rice, making your meal well-rounded.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins topped with a sprinkle of paprika or finely chopped herbs. You could also add a handful of cooked spinach folded into the casserole before baking for added color and nutrition. Presentation can elevate this comforting dish to a festive centerpiece.
Make Ahead and Storage
Storing Leftovers
Leftover Creamy Shrimp and Rice Casserole Recipe can be kept in an airtight container in the refrigerator for up to 3 days. Keeping it chilled properly maintains its creaminess and flavor, so you can enjoy it as a quick, satisfying meal the next day.
Freezing
You can freeze the casserole before baking by covering it tightly with plastic wrap and aluminum foil. It will keep well in the freezer for up to 2 months. To bake from frozen, simply add 10 to 15 minutes to the baking time and cover with foil to prevent over-browning.
Reheating
Reheat individual portions in the microwave, covered to retain moisture, or warm the entire dish in a 350°F oven until heated through, about 20 minutes. Adding a splash of milk before reheating can help renew the creamy texture.
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 in your casserole.
Is it possible to make this dish dairy-free?
Yes, you can substitute dairy ingredients with plant-based alternatives like coconut milk, vegan sour cream, and dairy-free cheeses, though the flavor and texture will vary slightly.
Can I prepare this casserole ahead of time?
Definitely. Assemble the casserole a day before and keep it covered in the fridge. Bake it fresh right before serving for the best taste and texture.

If you don’t have Old Bay, a mix of paprika, celery salt, black pepper, and a bit of cayenne pepper works well to mimic its distinctive flavor.
Is this recipe spicy?
This casserole has a mild warmth from the paprika and Old Bay but isn’t spicy. You can increase the heat by adding a pinch of cayenne if you prefer more kick.
