Cajun Shrimp and Crab over Polenta: A Taste of Louisiana

The aroma of Cajun spices always transports me back to my grandmother’s kitchen in New Orleans. I remember the warm, inviting atmosphere, the lively music playing in the background, and the incredible food that seemed to appear magically on the table. One dish that particularly stands out is a creamy, flavorful creation featuring shrimp, crab, and a perfectly seasoned sauce served over a bed of comforting polenta. It wasn’t exactly this recipe, but it evoked the same feeling, that deep-south warmth and flavor. That memory has fueled my own culinary adventures and inspired me to recreate and share dishes that capture the essence of that Southern charm.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 4-6
• Yield: 6 servings
• Dietary Type: Gluten-Free (if using certified gluten-free polenta)

Ingredients

• 1 lb large shrimp (peeled and tails removed)
• 1/2 lb lump crabmeat (cleaned)
• 2 cups andouille sausages (cut into thin rounds)
• 1 cup onion, chopped
• 1 cup green pepper, chopped
• 1 jalapeno, thin sliced (I leave the ribs in but remove the seeds, I like some heat)
• 1 3/4 cups chicken broth
• 2 teaspoons garlic, minced
• 1/4 teaspoon celery seed
• 1 teaspoon cajun seasoning
• 1/2 teaspoon Old Bay Seasoning
• 1 pinch red pepper flakes
• 1 tablespoon olive oil
• 1 tablespoon flour
• Salt to taste
• Pepper to taste

For the Polenta:

• 1 1/4 cups quick-cooking polenta (precooked maize meal, usually available at any major grocery store. If not, just buy regular polenta)
• 6 cups water
• 1/4 cup butter
• 1 cup Monterey Jack pepper cheese
• Salt to taste
• Pepper to taste

Equipment Needed

• Large saute pan
• Medium saucepan
• Whisk
• Wooden spoon
• Plate lined with paper towels

Instructions

1. Prepare the Sausage: In a large saute pan over medium heat, add the andouille sausage rounds and cook for 3-5 minutes, or until they are golden brown and have rendered some of their fat. Remove the sausage from the pan with a slotted spoon and place them on a plate lined with paper towels to drain excess grease. Reserve the flavorful drippings in the pan – this will form the base of your sauce!
2. Sauté the Vegetables: Add the chopped onion, green pepper, sliced jalapeno, and minced garlic to the pan with the sausage drippings. Cook for another minute or two, stirring frequently, until the vegetables begin to soften and become fragrant. Be careful not to burn the garlic.
3. Create the Cajun Sauce: Once the vegetables are slightly softened, sprinkle the flour over them. Stir continuously for about 1 minute to create a roux, which will help thicken the sauce. Gradually pour in the chicken broth, whisking constantly to prevent any lumps from forming. Bring the mixture to a medium heat and allow it to simmer until it thickens slightly.
4. Season the Sauce: Reduce the heat to medium-low and stir in the celery seed, cajun seasoning, Old Bay Seasoning, and red pepper flakes. Season generously with salt and pepper to taste. Remember that the andouille sausage and Old Bay already contribute salt, so taste as you go!
5. Cook the Shrimp: Add the shrimp to the sauce and cook until they begin to curl and turn pink. This should only take about 2-3 minutes, depending on the size of the shrimp. Be careful not to overcook the shrimp, as they will become rubbery.
6. Combine the Ingredients: Before the shrimp are fully cooked, add the cooked sausage back into the pan and mix well. Gently fold in the crabmeat, being careful not to break up the delicate lumps too much. Cook for another minute or so, just until the crab is heated through.
7. Prepare the Polenta: While the shrimp and crab are cooking, prepare the polenta according to the package directions. Whether you’re using quick-cooking or regular polenta, following the instructions will ensure the best results. Typically, this involves bringing the water to a boil in a saucepan, then gradually whisking in the polenta. Reduce the heat to low and cook, stirring frequently, until the polenta is thick and creamy.
8. Enrich the Polenta: Once the polenta is cooked, remove it from the heat and stir in the butter and Monterey Jack pepper cheese. Season with salt and pepper to taste. The cheese will melt into the polenta, creating a rich and flavorful base for the seafood sauce.
9. Serve: Spoon the creamy polenta into bowls and generously top with the Cajun shrimp and crab mixture. Garnish with fresh parsley or a sprinkle of extra Cajun seasoning, if desired. Enjoy this comforting and flavorful meal!

Expert Tips & Tricks

• Spice Level: Adjust the amount of jalapeno and red pepper flakes to control the heat level. If you prefer a milder dish, remove the seeds and membranes from the jalapeno entirely or omit the red pepper flakes altogether. For a spicier kick, consider adding a dash of hot sauce to the sauce.
• Seafood Quality: Use fresh, high-quality shrimp and crabmeat for the best flavor. If fresh crabmeat is unavailable, you can substitute with canned crabmeat, but be sure to drain it well before adding it to the sauce.
• Sausage Choice: Andouille sausage is the traditional choice for this dish, but you can substitute with other smoked sausages if you prefer. Kielbasa or chorizo would also work well.
• Make Ahead: The Cajun sauce can be made ahead of time and stored in the refrigerator for up to 2 days. Reheat gently before adding the shrimp and crab.
• Polenta Consistency: For a smoother polenta, use a whisk to stir it while it’s cooking. If the polenta becomes too thick, add a little more water to thin it out.

Serving & Storage Suggestions

Serve the Cajun Shrimp and Crab over Polenta immediately for the best flavor and texture. Garnish with fresh parsley or a sprinkle of extra Cajun seasoning for added visual appeal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave. The polenta may thicken as it cools, so you may need to add a little water or broth when reheating to restore its creamy consistency.

This dish is not suitable for freezing, as the texture of the polenta and seafood may be negatively affected.
