Gathering simple, fresh ingredients is the secret to making this dish sing with flavor and texture. Each element plays a crucial role — from the vibrant vegetables that add color and crunch to the creamy sauce that binds everything together in a harmonious, hearty meal.

• Shrimp (1.5 pounds, peeled and deveined): The star protein, tender and juicy, absorbing the Cajun spices beautifully.

• Green bell pepper (1, chopped): Brings fresh color and brightness.
• Celery stalks (2, chopped): Offers a mild crunch and aromatic background notes.
• Garlic (3 cloves, minced): Essential for an inviting and irresistible aroma.
• Cajun seasoning (2 tablespoons): Gives the dish its signature spicy, smoky kick — adjust to taste.
• All-purpose flour (1/4 cup): Thickens the sauce to creamy perfection.
• Chicken broth (3 cups): The savory liquid base that infuses the casserole with rich flavor.
• Heavy cream (1 cup): Makes the sauce luxuriously smooth and rich.
• Cheddar cheese (1/2 cup, shredded): Melts into the sauce, adding sharpness and gooey texture.
• Fresh parsley (1/4 cup, chopped): Lends a fresh herbal note and pretty green flecks.
• Salt and black pepper (to taste): Enhances all flavors without overpowering.
• Cooked white rice (2 cups): The comforting base that soaks up all the delicious sauce.

How to Make Creamy Cajun Shrimp & Rice Casserole

Step 1: Sauté the Vegetables

Start by heating olive oil in a large skillet over medium heat. Add the chopped onion, green bell pepper, and celery, sautéing until they’ve softened and released their natural sweetness — about 8 to 10 minutes. Toss in minced garlic and cook for another minute until fragrant, building a flavorful base that sets this casserole apart.

Step 2: Build the Cajun Roux

Sprinkle the Cajun seasoning and flour over the softened veggies, stirring constantly for 2 to 3 minutes. This step is crucial for developing a rich roux that will thicken the sauce and intensify those beloved Cajun flavors in the Creamy Cajun Shrimp & Rice Casserole.

Step 3: Create the Creamy Sauce

Gradually whisk in chicken broth, making sure no lumps form as the sauce starts to thicken over medium heat. Once it’s rich and velvety, stir in heavy cream and shredded cheddar cheese, allowing the cheese to melt completely while stirring. Season with salt and black pepper to taste — this sauce is where all the magic happens, perfecting the balance between spice and creaminess.

Step 4: Cook the Shrimp

Add the shrimp to the creamy sauce and cook for 3 to 5 minutes, just until they turn pink and opaque. Take care not to overcook — shrimp should be tender and juicy, never rubbery. This step brings the protein and sauce together in delicious harmony.

Step 5: Combine with Rice and Parsley

Gently fold cooked white rice and chopped parsley into the creamy shrimp mixture. This not only makes sure every bite is filled with flavor but also adds a lovely freshness, balancing the richness and giving the casserole vibrant flecks of green.

Step 6: Prepare for Baking

Pour the entire mixture into a greased 9×13 inch baking dish, smoothing it out evenly. This ensures even cooking and an inviting presentation for the casserole.

Step 7: Add the Crunchy Topping

In a small bowl, combine melted butter with Panko breadcrumbs, then sprinkle this mixture evenly over the casserole. This will bake into a golden, crispy crust that perfectly contrasts the creamy filling beneath.

Step 8: Bake to Perfection

Bake in a preheated oven at 375°F (190°C) for 20 to 25 minutes until the casserole is bubbly and the breadcrumb topping turns a beautiful golden brown. Let the dish rest for a few minutes before serving to let the flavors settle and the sauce thicken slightly.

Garnishes

Freshly chopped parsley or a sprinkle of extra Cajun seasoning on top adds a final pop of color and flavor. A squeeze of fresh lemon juice can brighten the dish even more, balancing the creamy richness with a hint of zesty freshness.

Side Dishes

This casserole pairs wonderfully with light, crisp sides like a simple green salad with a lemon vinaigrette or steamed green beans. The freshness and crunch from these sides complement the creamy, hearty casserole beautifully and add balance to your meal.

Creative Ways to Present

For a fun twist, try serving this casserole in individual ramekins, sprinkled with extra cheese just before the final bake for an indulgent finish. You can also add sliced green onions or chopped bell peppers on top for added color and texture, making it as stunning as it is delicious.

Make Ahead and Storage

Storing Leftovers

Store any leftover Creamy Cajun Shrimp & Rice Casserole in an airtight container in the refrigerator for up to 3 days. The flavors meld beautifully overnight, often tasting even better the next day.

Freezing

You can freeze this casserole before baking by covering the dish tightly with plastic wrap and foil. It will keep well for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator and bake as instructed, adding a bit of extra time if baking from frozen.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for 15 to 20 minutes until warmed through, keeping the breadcrumb topping crispy. Alternatively, microwaving works well but may soften the topping. A quick broil at the end can restore some crispness.

FAQs

Can I use frozen shrimp for this casserole?

Absolutely! Just be sure to thaw the shrimp completely and pat them dry before cooking to avoid excess moisture, which can affect the sauce’s consistency.

Is this dish very spicy?

The spice level depends on the Cajun seasoning you use. You can adjust the amount to suit your taste, making it mild or adding a bit more heat for a bold kick.

Can I substitute the white rice for brown rice or quinoa?

Yes, but keep in mind the texture and cooking times differ. Brown rice is chewier and nuttier, so pre-cook it fully and expect a heartier bite. Quinoa works too for a protein boost but will change the overall flavor slightly.

What can I use instead of heavy cream?

You can substitute half-and-half or whole milk mixed with a small amount of butter for a lighter sauce, but the casserole won’t be quite as creamy or rich.

Can I make this casserole vegetarian?

For a vegetarian version, swap shrimp for hearty vegetables like mushrooms or zucchini, and use vegetable broth instead of chicken broth for the sauce base.
