Pasta Mardi Gras Pappadeaux Recipe: Cajun-Spiced Seafood Celebration

This Cajun-inspired dish brings the vibrant flavors of New Orleans to your table. A rich, spiced cream sauce clings to al dente pasta, creating a base that celebrates bold seasoning and fresh ingredients.

The addition of seafood elevates this pasta into a restaurant-quality celebration, perfect for Mardi Gras or any occasion calling for a taste of the Big Easy. Every bite delivers a harmony of heat, creaminess, and briny sweetness.

Ingredients for Pasta Mardi Gras Pappadeaux

Rich, bold, and briny—this dish captures New Orleans in every bite with fresh seafood and Cajun spice.

The seafood is the star here. Pappadeaux uses fresh Gulf shrimp and scallops—look for wild-caught if possible, or ask your fishmonger for the day’s best. For the pasta, fettuccine holds the creamy sauce beautifully, but linguine works too. The cream needs to be full-fat to stand up to the bold seasoning without curdling. If you’re buying Cajun seasoning, Tony Chachere’s is a solid choice.

No shrimp? Crawfish tails (if you can find them) or firm white fish like cod or halibut work well. Swap heavy cream for half-and-half at half the amount, but the sauce won’t be as rich. Dry white wine is ideal, but substitute chicken stock with a splash of lemon juice in a pinch. Fresh garlic is a must—powdered won’t give you the same depth.

This dish is best served fresh, but leftovers keep for 2 days in the fridge. Reheat gently in a skillet with a splash of milk to loosen the sauce. For Mardi Gras, prep the seafood and sauce ahead, then combine just before serving.

Step-by-Step Instructions for Pasta Mardi Gras Pappadeaux

Master this technique and you’ll deliver restaurant-quality seafood pasta with bold Cajun flavor.

Step 1: Prepare the Seafood and Pasta

Pat the 1 lb Large Shrimp and 0.5 lb Scallops completely dry with paper towels. This step is crucial—excess moisture prevents proper searing. Season both sides of the seafood evenly with 1 tsp Salt and 0.5 tsp Black Pepper, then dust lightly with 2 tbsp Cajun Seasoning.

Meanwhile, cook the 12 oz Fettuccine Pasta in salted boiling water until al dente, about 1 minute less than package directions. Reserve 1 cup of pasta water before draining. The pasta will finish cooking in the sauce, absorbing all those rich flavors.

Step 2: Sear the Seafood to Perfection

Heat 2 tbsp Unsalted Butter in a large skillet over medium-high heat until the foaming subsides. Add the shrimp in a single layer and cook for 1-2 minutes per side until opaque and pink. Remove to a plate and keep warm.

In the same skillet, add the remaining 6 tbsp Unsalted Butter (totaling 0.5 cup Unsalted Butter). Once hot, add the scallops and cook for 2-3 minutes per side until golden brown and cooked through. Transfer to the plate with shrimp. The fond left in the pan will build the sauce’s depth.

Step 3: Build the Cajun Cream Sauce

Reduce heat to medium and add the 4 cloves Garlic Cloves (minced) to the skillet. Sauté for 30 seconds until fragrant. Deglaze with 0.5 cup White Wine, scraping up all browned bits. Simmer for 2 minutes until reduced by half.

Pour in 1 cup Chicken Stock and 1.5 cups Heavy Cream. Bring to a gentle simmer and cook for 5 minutes until slightly thickened. Stir in the zest and juice of 1 whole Lemon. The acidity balances the richness perfectly.

Step 4: Combine and Finish

Add the cooked pasta, shrimp, and scallops to the sauce. Toss gently to coat everything evenly. Sprinkle in 0.5 cup Parmesan Cheese and stir until melted and creamy. If the sauce is too thick, add reserved pasta water 1 tbsp at a time until it reaches your desired consistency.

Cook for an additional 2-3 minutes, allowing the flavors to meld. Taste and adjust seasoning if needed. The pasta should be perfectly coated with a velvety, spiced cream sauce clinging to every strand.

Step 5: Garnish and Serve Immediately

Transfer to serving plates and garnish with 0.5 cup Green Onions (thinly sliced) and 0.25 cup Fresh Parsley (chopped). The fresh herbs add a pop of color and brightness that cuts through the richness.

Serve with extra lemon wedges on the side. Each bite should deliver tender seafood, creamy pasta, and that signature Cajun kick that defines this celebration dish.

Pro Cooking Tips for This Dish

Seafood Searing Secrets

Pat your shrimp and scallops bone-dry before seasoning—this prevents steaming and ensures a perfect golden crust. I use paper towels and press firmly. The Cajun seasoning should cling to the surface, not dissolve in moisture. 🔥

Pasta Perfection

Cook your fettuccine to al dente—it finishes in the sauce. Reserve that pasta water; its starch helps emulsify the sauce for a silky texture. I always use at least 1 cup for adjusting consistency later.

Sauce Building

After deglazing with white wine, let it reduce by half before adding liquids. This concentrates flavor. Simmer the cream sauce gently—boiling can cause curdling. Stir frequently with a wooden spoon to prevent hot spots.

Temperature Control

Keep seafood warm on a plate tented with foil while building the sauce. Return it to the pan only at the end to avoid overcooking. The internal temp for shrimp should hit 145°F and scallops 125°F—use an instant-read thermometer for accuracy.

Final Touches

Add Parmesan off-heat to prevent clumping. Toss everything together just before serving. The acid from lemon zest brightens the rich sauce beautifully. I always taste one last time and adjust Cajun seasoning if needed.

Plating Like a Pro

Twirl pasta onto plates with tongs, then arrange shrimp and scallops on top. Garnish with green onions and parsley for color. A final squeeze of lemon juice right before serving makes all the flavors pop. ✨
