How to Make Cajun Shrimp and Cornbread Casserole

Toss Shrimp: Pat shrimp dry, then coat with Cajun seasoning, minced garlic, and melted butter until all are evenly spiced.
Sauté Shrimp: Heat a skillet over medium-high (375°F) until hot, then cook shrimp in butter 2–3 minutes per side until pink, fragrant, and just firm.

For the Cornbread Batter:

Mix Dry Ingredients: In a large bowl, whisk together cornmeal, all-purpose flour, baking powder, and sugar until fully blended, smooth, and free of any lumps.
Combine Wet Ingredients: Pour milk and melted butter into a separate bowl, whisk in beaten eggs, then stir everything into dry mixture until a smooth, golden batter forms.

To Assemble and Bake:

Layer Shrimp: Spread cooked shrimp evenly across the bottom of a greased 9×13-inch baking dish, arranging tails inward and leaving no crowding.
Pour Batter: Gently pour cornbread batter over shrimp in an even layer, using a spatula to smooth the top and ensure consistent thickness.
Bake: Bake casserole at 375°F for 25–30 minutes until the cornbread top is deep golden brown, edges set, and center springs back when touched.

Optional: Sprinkle with chopped green onions and shredded cheddar just before serving.

Tips for the Best Cajun Shrimp and Cornbread Casserole

Use Fresh Shrimp: For the juiciest, most flavorful Cajun Shrimp and Cornbread Casserole, choose fresh or properly thawed shrimp to avoid a rubbery texture.
Don’t Overcook Shrimp: Sauté shrimp just until pink and firm—overcooking makes them tough and detracts from the dish’s tender bite.
Mix Batter Gently: Stir the cornbread batter until just combined; overmixing can make the bread dense instead of light and fluffy.
Even Layering Matters: Spread shrimp in a single, even layer before pouring batter for consistent baking and balanced bites in every serving.
Check Oven Temperature: Use an oven thermometer to ensure 375°F is precise—too hot and the cornbread top may burn before the center is cooked.
Let It Rest: Allow the casserole to cool 5 minutes before serving to let flavors meld and ease slicing without crumbling.

Make Ahead Options

These Cajun Shrimp and Cornbread Casserole preparations are perfect for busy weeknights!

This approach saves you prep time while allowing you to enjoy the same delicious flavor, just as vibrant as if you made it all in one go.

Cajun Shrimp and Cornbread Casserole Recipe FAQs

How do I know if the shrimp is fresh and ready to use for this casserole?
Choose shrimp that looks translucent and moist, with a mild ocean scent—avoid any that smell strongly fishy or have dark spots all over. Fresh shrimp should feel firm to the touch, not slimy or mushy. Using fresh or properly thawed shrimp makes a huge difference in texture and flavor for this dish!

What’s the best way to store leftover Cajun Shrimp and Cornbread Casserole?
Once cooled, transfer leftovers to an airtight container and refrigerate. It will keep beautifully for 3 to 4 days. Before reheating, I recommend portioning it so you only heat what you need to keep the rest fresh and tasty.

Can I freeze Cajun Shrimp and Cornbread Casserole for later?
Absolutely! To freeze, let the casserole cool completely, then cut into single servings if you like. Wrap each portion tightly in plastic wrap and foil, or place in sealed freezer-safe containers or bags. Label with date and store in the freezer for up to 2 months. Thaw overnight in your fridge before reheating gently in a 350°F oven for about 20-25 minutes.

My cornbread top turns out dense sometimes—what am I doing wrong?
That’s a common hiccup! Be sure to mix the dry and wet ingredients just until combined—overmixing develops gluten and makes the cornbread heavy. Also, check that your baking powder is fresh; expired leavening means poor rise. Lastly, even heat and layering shrimp evenly under the batter help the cornbread cook uniformly and stay light.

Is Cajun Shrimp and Cornbread Casserole safe for pets or people with seafood allergies?
Since this recipe centers around shrimp, it’s not safe for those allergic to shellfish or for pets, who should never have spicy or seasoned human food. If you have allergy concerns, you can try substituting cooked chicken with similar seasoning for a safe, tasty alternative. Always label leftovers clearly to avoid confusion!
