Why You’ll Love This Recipe
This cheesy shrimp and rice casserole is incredibly easy to prepare and requires minimal cooking before it goes into the oven.
The creamy rice provides a rich and satisfying base, while Cajun seasoning gives the shrimp a flavorful kick without requiring a long list of spices.
It is also an excellent way to use leftover cooked rice. Chilled, day-old rice works particularly well because it holds its texture while absorbing the creamy sauce.
The melted cheese on top creates a golden, bubbling finish that makes this casserole especially inviting when served straight from the oven.
Ingredients
For the Cajun Shrimp
| Ingredient | Amount |
| Large shrimp, peeled and deveined | 1 lb (450 g) |
| Olive oil | 1 tablespoon |
| Cajun or Creole seasoning | 1 tablespoon |
For the Creamy Rice
| Ingredient | Amount |
| Cooked long-grain white rice, cooled | 3 cups |
| Heavy cream | 1 cup (240 ml) |
| Vegetable broth | ½ cup (120 ml) |
| Garlic powder | 1 teaspoon |
| Onion powder | ½ teaspoon |
| Shredded mozzarella and mild cheddar | 2 cups, divided |
| Smoked paprika | ½ teaspoon |
| Fresh parsley, chopped | 1 tablespoon |
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish with cooking spray, butter, or a small amount of olive oil.
2. Prepare the Shrimp
Place the peeled and deveined shrimp in a medium bowl.
Add the olive oil and Cajun seasoning. Toss gently until every shrimp is evenly coated.
Set aside while you prepare the rice mixture.
3. Make the Creamy Rice Mixture
In a large mixing bowl, combine the cooled cooked rice, heavy cream, vegetable broth, garlic powder, onion powder, and 1 cup of the shredded cheese.
Stir gently until the rice is evenly coated and the ingredients are well combined.
Avoid aggressively mashing the rice, as keeping the grains intact gives the finished casserole a better texture.
4. Assemble the Casserole
Transfer the creamy rice mixture to the prepared baking dish.
Use a spatula or the back of a spoon to spread it into one even layer.
5. Add the Shrimp
Arrange the seasoned shrimp evenly over the rice.
Try to keep the shrimp in a single layer so they cook evenly.
Sprinkle the remaining 1 cup of shredded cheese over the shrimp.
6. Add Smoked Paprika
Lightly sprinkle the smoked paprika over the cheese.
This adds a subtle smoky flavor and helps create an attractive golden appearance as the casserole bakes.
7. Bake
Place the casserole in the preheated oven and bake uncovered for 18–22 minutes.
The cheese should be fully melted and bubbling around the edges, while the shrimp should be pink, opaque, and cooked through.
Avoid overbaking the shrimp, as they can become tough and rubbery when cooked for too long.
8. Rest and Garnish
Remove the casserole from the oven and allow it to rest for approximately 5 minutes.
Sprinkle the freshly chopped parsley over the top.
Serve warm while the cheese is still melted and creamy.
Best Tips for Perfect Shrimp Casserole
Use large shrimp whenever possible because they are less likely to overcook during baking.
For the best rice texture, use cooked rice that has been cooled completely. Leftover refrigerated rice is particularly convenient for this recipe.
Do not overcrowd the shrimp. Arranging them in a single layer helps them cook more evenly.
Keep an eye on the casserole during the final few minutes of baking. Once the cheese is melted and bubbling and the shrimp are cooked through, it is ready.
For extra browning, you can place the casserole under the broiler for 1–2 minutes, watching it closely the entire time.
Best Ingredient Options
Shrimp
Fresh or thawed frozen shrimp can be used. If using frozen shrimp, thaw them completely and pat them dry before seasoning.
Rice
Long-grain white rice is ideal, but cooked jasmine or basmati rice can also work well.
Brown rice can be substituted if you prefer a heartier texture, although the casserole will be slightly denser.
Cheese
A combination of mozzarella and mild cheddar provides excellent melting quality and flavor.
For a stronger cheese flavor, try sharp cheddar, Monterey Jack, Colby Jack, or a Mexican-style shredded cheese blend.
Cream
Heavy cream creates the richest texture. For a slightly lighter casserole, you can substitute half-and-half, although the finished dish may be less rich.
Recipe Variations
Spicy Cajun Shrimp Casserole
Add ¼–½ teaspoon of cayenne pepper to the shrimp seasoning for additional heat.
Cajun Chicken and Shrimp Casserole
Replace half of the shrimp with small pieces of cooked chicken for a hearty surf-and-turf-style casserole.
Vegetable-Loaded Version
Add sautéed bell peppers, onions, spinach, or mushrooms to the rice mixture before assembling the casserole.
Extra Cheesy Version
Add another ½ cup of shredded cheese to the topping for an even richer, cheesier finish.
Garlic Butter Shrimp Version
Toss the shrimp with 1 tablespoon of melted butter and 1 minced garlic clove along with the Cajun seasoning before arranging them over the rice.
What to Serve With Cajun Shrimp & Rice Casserole
This casserole is filling enough to serve as a complete dinner, but it pairs beautifully with simple sides.
Serve it with a crisp green salad, steamed broccoli, roasted vegetables, sautéed green beans, or a simple cucumber salad.
Warm dinner rolls or crusty bread are also excellent for soaking up the creamy sauce.
For a lighter meal, pair a smaller portion of the casserole with a large fresh salad.
Make-Ahead Instructions
You can prepare the creamy rice mixture several hours ahead of time and keep it covered in the refrigerator.
For the best texture, season and add the shrimp shortly before baking.
If assembling the entire casserole in advance, keep it refrigerated and bake it within the same day. Because the ingredients will be cold, you may need to add several extra minutes to the baking time.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3 days.
Because shrimp can become dry when repeatedly reheated, only reheat the portion you plan to eat.
Reheating
For the best results, reheat individual portions in the microwave.
Cover loosely and heat in short intervals, stirring the rice gently between intervals when possible.
You can also reheat the casserole in a covered oven-safe dish at 325°F (165°C) until warmed through.
Avoid overheating because this can make the shrimp chewy.
Freezing
This casserole is best enjoyed fresh, but leftovers can be frozen if necessary.
Place cooled portions in freezer-safe airtight containers and freeze for up to 2 months.
Thaw overnight in the refrigerator before reheating.
The texture of the creamy rice and cheese may change slightly after freezing and thawing.
Common Mistakes to Avoid
Using Wet Shrimp
Excess moisture can dilute the seasoning and affect the texture of the casserole. Pat thawed shrimp dry before seasoning.
Overcooking the Shrimp
Shrimp cook quickly. Bake only until they are pink and opaque.
Using Hot Rice
Very hot rice can make the creamy mixture overly soft. Cool the cooked rice before mixing it with the cream and broth.
Skipping the Resting Time
Allowing the casserole to rest for a few minutes helps the creamy mixture settle and makes serving easier.
Adding Too Much Cajun Seasoning
Cajun seasoning can vary significantly in saltiness and heat. If your seasoning is particularly salty, start with less and adjust according to taste.
