How to Make Shrimp and Cheddar Rice Casserole Recipe
Step 1: Preheat and Prep Your Baking Dish
Start things off by preheating your oven to 350°F (175°C). Grease your baking dish with butter or a nonstick spray to ensure your casserole won’t stick and will develop that beautiful golden crust you’re aiming for.
Step 2: Sauté the Aromatics and Veggies
Melt butter in a large skillet over medium heat, then add the chopped onion, garlic, bell pepper, and celery. Sauté these for about 5 minutes until they soften and release their wonderful aromas. This base builds so much of the flavor, and getting these veggies tender is key to a perfect casserole.
Step 3: Cook the Shrimp
Next, toss the peeled shrimp into the skillet with the vegetables and cook for 2 to 3 minutes until they turn pink and opaque. Shrimp cooks fast, so keep an eye on it. Once they’re done, remove the skillet from the heat — these sweet, tender morsels are ready to shine.
Step 4: Combine the Creamy Mixture
Grab a large bowl and mix together cooked rice, shredded cheddar, grated Parmesan, milk, heavy cream, sour cream, and the array of seasonings: Old Bay, paprika, salt, black pepper, thyme, and oregano. This creamy blend is the heart of your Shrimp and Cheddar Rice Casserole Recipe, ensuring every bite is smooth, cheesy, and perfectly seasoned.
Step 5: Fold in Shrimp and Vegetables
Gently stir the cooked shrimp and sautéed vegetables into the cheese and rice mixture. Carefully combining everything now ensures that those flavors meld without breaking up the shrimp too much.
Step 6: Assemble in the Baking Dish
Transfer your creamy, cheesy mixture into the prepared baking dish, smoothing it out evenly. For those craving a bit of texture contrast, sprinkle the optional breadcrumbs evenly over the top — it will bake up with a satisfying golden crunch.
Step 7: Bake to Perfection
Bake the casserole for 25 to 30 minutes, until it’s bubbly and the top turns a gorgeous golden brown. As it bakes, the flavors deepen, the cheese melts into everything, and the crust crisps just right.
Step 8: Garnish and Get Ready to Eat
Once out of the oven, sprinkle fresh chopped parsley over the top for a burst of color and brightness. Then it’s time to dig in to that soul-warming Shrimp and Cheddar Rice Casserole Recipe you made from scratch!
How to Serve Shrimp and Cheddar Rice Casserole Recipe

Garnishes
Boost the dish’s flavor and presentation by adding a sprinkle of fresh parsley or chives just before serving. A light drizzle of lemon juice can also brighten the rich, creamy notes and complement the shrimp beautifully.
Side Dishes
This casserole is wonderfully filling on its own but pairs perfectly with simple sides like a crisp green salad, roasted asparagus, or steamed green beans. The freshness and crunch from veggies are a great contrast to the creamy, cheesy casserole.
Creative Ways to Present
For a fun twist, try serving the casserole in individual ramekins for a charming personal touch. Or spoon it over a bed of lightly sautéed spinach or kale for a nourishing, colorful plate. Offering some crusty bread on the side to mop up every last bit is always a winner too.
Make Ahead and Storage
Storing Leftovers
Store any leftover Shrimp and Cheddar Rice Casserole Recipe in an airtight container in the refrigerator for up to 3 days. It keeps its flavor and texture nicely when reheated, making it a fantastic next-day meal.
Freezing
If you want to prep ahead, this casserole freezes well. Wrap it tightly with plastic wrap and aluminum foil or store it in a freezer-safe container. It can be frozen for up to 2 months, perfect for those busy days when you need a quick and comforting dinner.
Reheating
To reheat, thaw overnight in the fridge if frozen. Warm it gently in the oven at 350°F (175°C) for about 20 minutes or until heated through, which helps preserve the casserole’s creamy texture and crisp topping. You can also microwave smaller portions, stirring occasionally.
FAQs
Can I use frozen shrimp for this casserole?
Absolutely! Just make sure to thaw and pat them dry before cooking to prevent extra moisture in your casserole. This will keep the texture just right.
Is it possible to make this casserole dairy-free?
You can swap out the dairy ingredients for plant-based alternatives like coconut milk and vegan cheese, though the texture might differ slightly. Using dairy-free sour cream and cream substitute can keep the creamy consistency intact.
What’s a good substitute for Old Bay seasoning?
If you don’t have Old Bay, try a mix of paprika, celery salt, black pepper, and a pinch of cayenne for a similar seafood-friendly spice profile that still makes the flavors pop.
Can I add other vegetables to the casserole?
Definitely! Mushrooms, spinach, or zucchini would be great additions that complement the shrimp and cheese while adding complexity and nutrition.
How can I make this casserole spicier?
Add a pinch or two of cayenne pepper or some chopped jalapeños in the sautéed veggies stage. You can also include a spicy cheese like pepper jack for an extra kick.
