• Celery (2 stalks, chopped) – Contributes crunch and flavor; fennel can replace for a unique twist.
• Medium red bell pepper (1, finely chopped) – Adds sweetness and color; green bell pepper can be used instead.
• Long-grain white rice (1 1/2 cups, preferably converted or parboiled) – Base of the casserole; brown rice can be used for a healthier option.
• Whole water chestnuts (5-ounce can, halved and chopped) – Adds crunch and texture; fresh water chestnuts can be used if available.
For the Creamy Mixture
• Butter (6 tablespoons, divided) – Adds richness and moisture; olive oil can substitute for a dairy-free option.

• Mayonnaise (1/2 cup, preferably full-fat) – Adds moisture and tang; Greek yogurt is a lighter alternative.

Step‑by‑Step Instructions for Southern Creamy Shrimp and Crab Casserole with Rice
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it heats, prepare a 13 x 9-inch baking dish by greasing it with butter or a non-stick cooking spray. This ensures your creamy shrimp and crab seafood casserole has a beautiful golden crust once it’s baked and prevents sticking.
Step 2: Cook the Shrimp
In a large pot, bring water to a gentle boil and season it with salt and freshly ground black pepper. Add the uncooked shrimp and allow them to cook for about 30 seconds to 1 minute, just until they turn pink. Drain the shrimp and cool them quickly under cold running water to stop the cooking process, preventing rubbery texture later.
Step 3: Sauté the Vegetables
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Add the finely chopped onion, chopped celery, and red bell pepper, sautéing them for approximately 5-6 minutes or until they become soft and aromatic. This creates a flavorful base for your casserole, enhancing the overall taste of the shrimp and crab seafood dish.
Step 4: Cook the Rice
To the saucepan with sautéed vegetables, add water and bring it to a boil. Stir in the long-grain white rice, cover the pot with a lid, then reduce the heat to low. Let the rice cook undisturbed for about 10-12 minutes, then remove from heat and let it sit covered for an additional 10 minutes. This process ensures fluffy rice that beautifully complements the creaminess.
Step 5: Combine Ingredients
In a large mixing bowl, combine the cooked rice and vegetable mixture with the chopped water chestnuts, half and half, mayonnaise, tomato puree, lemon juice, paprika, cayenne, nutmeg, and half of the chopped fresh parsley. Stir well to blend all the ingredients together, adjusting seasoning with salt and pepper to taste. This will be the flavorful base of your casserole.
Step 6: Assemble the Casserole
In the prepared baking dish, spread one-third of the rice and seafood mixture as the base layer. Next, evenly distribute half of the cooked shrimp and crab over the top. Repeat these layers until you finish with the last third of the rice mixture on top. This layering technique ensures every bite of your Southern creamy shrimp and crab seafood casserole is stuffed with seafood goodness.
Step 7: Prepare the Topping
In a small bowl, mix the remaining coarse fresh breadcrumbs with 2 tablespoons of melted butter until well combined. Sprinkle this buttery breadcrumb mixture evenly over the casserole’s top layer for added texture and crunch. Cover the dish loosely with foil to help everything retain moisture while baking.
Step 8: Bake the Casserole
Place the assembled casserole in the preheated oven and bake for 30-40 minutes. About 10 minutes before it’s done, carefully remove the foil to allow the breadcrumb topping to crisp up beautifully. Keep an eye out for a lovely golden-brown color that indicates your creamy shrimp and crab seafood casserole is ready to serve.

How to Store and Freeze Shrimp and Crab Seafood Casserole
Fridge: Store leftover creamy shrimp and crab seafood casserole in an airtight container for up to 3 days. Reheat in the oven for best texture.
Freezer: If you need to freeze the casserole, omit the breadcrumb topping before freezing to prevent sogginess. Wrap tightly in plastic wrap and aluminum foil for up to 2 months.
Reheating: Thaw in the refrigerator overnight before reheating. Bake at 350°F until heated through, about 25-30 minutes.
Room Temperature: Do not leave the casserole at room temperature for more than 2 hours to ensure food safety.

This helps maintain quality and ensures that every bite is just as delicious as when freshly made! Enjoy a hassle-free meal that’s sure to impress your family and friends!

Expert Tips for Shrimp and Crab Seafood
-
Avoid Overcooking Shrimp: Ensure shrimp is cooked just until pink during boiling. Overcooked shrimp can turn leathery and tough, negatively affecting the creamy shrimp and crab seafood casserole.
-
Layering Matters: For an even distribution of flavors and textures, layer the casserole in three parts. This way, each serving will have a perfect mix of shrimp, crab, and creamy goodness.
-
Use Quality Ingredients: Opt for wild-caught American gulf shrimp for the best taste. Fresh ingredients elevate the flavor profile, ensuring every bite of your seafood casserole is spectacular.
-
Fresh vs. Frozen: If using frozen seafood, make sure to thoroughly thaw and drain it before cooking to avoid excess moisture in your casserole.
-
Breadcrumb Alternatives: If you want a lighter topping, try panko breadcrumbs or crushed buttery crackers like Ritz for a deliciously crispy finish on your shrimp and crab seafood casserole.
-
Make Ahead Tip: Prepare the casserole a day in advance, but wait to add the breadcrumb topping until just before baking to maintain its crunch.

Creamy Shrimp and Crab Seafood Casserole Recipe FAQs
How do I choose the right shrimp for my casserole?
Absolutely! For the best flavor, I recommend using wild-caught American Gulf shrimp. Look for shrimp that are firm and have a mild ocean smell, avoiding any with dark spots or a strong fishy odor.
How should I store leftover shrimp and crab seafood casserole?
Leftovers should be kept in an airtight container in the fridge for up to 3 days. When reheating, it’s best to pop it back in the oven to preserve the crunchy topping and moisture, roughly 25-30 minutes at 350°F.
Can I freeze the shrimp and crab seafood casserole?
Yes, you can! Just omit the breadcrumb topping before freezing. Wrap the casserole tightly in plastic wrap and aluminum foil and store in the freezer for up to 2 months. When ready to enjoy, thaw in the refrigerator overnight and bake at 350°F until heated through.
What should I do if my casserole seems too dry?
If the casserole dries out, don’t worry! You can add a little milk or half-and-half before reheating to restore creaminess. Stir it gently to incorporate, covering it loosely with foil while it heats to lock in moisture.
Is this casserole suitable for people with shellfish allergies?
If you’re cooking for someone with a shellfish allergy, it’s best to substitute the shrimp and crab with other proteins like chicken or a mix of vegetables. Always check labels and ensure all ingredients are allergy-friendly!
How can I ensure my shrimp doesn’t become rubbery in the casserole?
That’s a great question! To prevent rubbery shrimp, make sure to boil them just until they turn pink—about 30 seconds to a minute—and cool them promptly under cold water. This will stop the cooking process and help keep them tender and juicy.
