There’s something undeniably comforting about tucking into a dish that layers tender seafood with creamy, spicy goodness—and that, my friends, is exactly what this Baked Creamy Cajun Shrimp Casserole delivers. I still remember the first time I stirred together a heap of sautéed bell peppers and onions with sweet corn and a velvety blend of mushroom soup and sour cream. The kitchen filled with the warm hum of bubbling cheese and spice, and by the time the shrimp, seasoned with a kiss of Cajun heat, joined the party, I was already sold. This casserole is more than a simple dinner; it’s a celebration of Southern-inspired flavors that feel like a hug in a baking dish.
As an enthusiastic home cook who’s always hunting for easy, crowd-pleasing recipes, I love how this casserole balances convenience with show-stopping taste. It’s a beginner-friendly bake that only takes about 20 minutes of prep and 30 minutes in the oven, yet it looks—and tastes—like a dish you’d order at a cozy seafood bistro. The bright pops of red and green peppers, the golden blanket of cheddar and Parmesan, and the gentle kick of Cajun seasoning all come together to create a meal that’s as beautiful on the table as it is on the palate. Gather your ingredients, invite your family or friends, and get ready for one of the most satisfying dinners you’ll whip up all week.
KEY INGREDIENTS IN BAKED CREAMY CAJUN SHRIMP CASSEROLE
Before diving into the cooking process, let’s talk about the stars of this recipe. Every ingredient plays an important role in building layers of texture, color, and flavor. From the spicy, succulent shrimp to the creamy cheese topping and the earthy notes of sautéed veggies, here’s how each component contributes to the magic of this casserole:
- Large shrimp
These peeled and deveined gems bring a tender, succulent protein base that soaks up the bold Cajun seasoning. Their mild sweetness pairs perfectly with the creamy sauce.
- Olive oil
A drizzle of olive oil helps the shrimp absorb the Cajun spices without drying out, and it adds a hint of fruity richness to the pan.
- Cajun seasoning
A fragrant blend of paprika, garlic powder, onion powder, and a few secret spices that inject a gentle heat and distinctive Southern flair into every bite.
- Butter
Melting in the skillet, butter creates a luscious coating for the onions, garlic, and peppers, lending a rich, silky texture to the vegetable base.
- Onion
Finely chopped onion adds a sweet, aromatic depth when sautéed, forming the foundation of flavor for the creamy sauce.
- Garlic
Minced garlic offers a punchy, savory note that elevates each spoonful, infusing the dish with its irresistible warmth.
- Red bell pepper
Diced red peppers bring a vibrant color and crunchy sweetness that brightens up the rich casserole.
- Green bell pepper
With its fresh, slightly grassy flavor, green bell pepper contrasts the red pepper beautifully and adds extra texture.
- Frozen corn kernels
These little bursts of sweetness and poppy texture blend seamlessly into the sautéed veggies, providing playful contrast with each forkful.
- Cream of mushroom soup
Acting as the creamy backbone, this soup incorporates an earthy, savory note while binding the rice and shrimp together.
- Sour cream
Stirred into the soup, sour cream enhances the luscious mouthfeel and introduces a gentle tang that balances the spices.
- Shredded cheddar cheese
A sharp, melty layer that blankets the top of the casserole, delivering that coveted golden, gooey finish.
- Grated Parmesan cheese
Sprinkled alongside the cheddar, Parmesan contributes a nutty, salty bite that rounds out the cheesy topping.
- Cooked rice
Steamed rice soaks up the creamy sauce, transforming this bake into a hearty, comforting main course.
- Fresh parsley
Chopped parsley adds a final pop of green and a herby brightness that cuts through the richness.
- Salt and pepper
These pantry staples are essential for bringing all the flavors into perfect harmony. Adjust to taste!
HOW TO MAKE BAKED CREAMY CAJUN SHRIMP CASSEROLE
Ready to get cooking? This is where all the delicious ingredients you’ve gathered come together. Follow these steps closely for a casserole that’s golden, bubbly, and packed with flavor.
1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking and ensure crisp edges.
2. In a medium bowl, toss the shrimp with olive oil and Cajun seasoning until each piece is thoroughly coated. Let them rest while you prepare the rest of the dish—this helps the flavors meld.
3. In a large skillet over medium heat, melt the butter. Add the chopped onion and minced garlic, then sauté until the onion becomes translucent and fragrant, about 3–4 minutes.
4. Stir in the diced red and green bell peppers. Cook until the peppers soften and release their natural sweetness, about 5 minutes, stirring occasionally.
5. Add the frozen corn kernels and let them cook for an additional 2–3 minutes, until heated through. This step brings out their sweet crunch.
6. Remove the skillet from heat. Stir in the cream of mushroom soup and sour cream, mixing thoroughly until you have a smooth, creamy sauce.
7. Fold in the cooked rice, making sure every grain is coated with the velvety sauce. Season with salt and pepper to taste.
8. Transfer half of the rice mixture to the prepared baking dish, spreading it out in an even layer to support the shrimp.
9. Arrange the seasoned shrimp over the rice layer, spacing them evenly for uniform cooking.
10. Sprinkle half of the shredded cheddar and Parmesan cheese over the shrimp, covering them with a cheesy blanket.
11. Top with the remaining rice mixture, smoothing it gently, then sprinkle the rest of the cheeses on top.
12. Cover the dish with foil and bake in the preheated oven for 20 minutes. This traps steam and ensures everything heats through without drying out.
13. Remove the foil and continue baking for an additional 10 minutes, or until the cheese on top is melted, golden, and bubbly.
14. Once baked, let the casserole cool slightly—about 5 minutes—before removing from the oven. This brief rest helps it set for cleaner slices.
15. Sprinkle with chopped fresh parsley, then serve warm and dig into your creamy Cajun shrimp masterpiece.

HOW TO STORE BAKED CREAMY CAJUN SHRIMP CASSEROLE
Whether you end up with leftovers or want to make it ahead for a dinner party, proper storage ensures that your creamy Cajun shrimp casserole stays as delicious as the day you baked it. Pay attention to temperature, airtight sealing, and reheating methods to preserve texture and flavor. Here are a few approaches to keep in mind:
- Refrigerator storage
Allow the casserole to cool completely at room temperature (no more than two hours), then cover the baking dish tightly with foil or transfer portions to airtight containers. Store in the fridge for up to 3 days. Reheat individual servings in the microwave or warm the entire dish in a 350°F oven until heated through.
- Freezer option
For longer-term storage, assemble the casserole (without baking), wrap the unbaked dish in plastic wrap and then foil, and freeze for up to one month. When you’re ready, thaw overnight in the refrigerator, remove the wrappings, and bake as directed.
- Reheating tips
To prevent drying out, cover the casserole with foil when reheating. If using a microwave, add a splash of water or cream and cover with a microwave-safe lid to keep it moist.
- Portion control
Consider dividing the casserole into individual ramekins before baking and storage. This makes reheating quick and easy, perfect for lunches or single servings without disturbing the rest of the dish.
