Ingredients

  

For the Cajun Seasoning

• 2 tsp paprika
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp dried oregano
• 1 tsp dried thyme
• 1/2 tsp cayenne pepper adjust to taste
• 1/2 tsp black pepper
• 1 tsp salt

For the Pasta

• 12 oz fettuccine pasta
• 1 lb large shrimp peeled and deveined
• 3 tbsp olive oil
• 4 cloves garlic minced
• 1 medium bell pepper sliced
• 1/2 cup white wine or chicken broth
• 1 cup heavy cream
• 1/2 cup parmesan cheese grated
• 2 tbsp butter
• 3 green green onions chopped
• 2 tbsp fresh parsley chopped

Equipment

• Large Skillet
• Large Pot
• Colander
• Mixing Bowl

Method

 

Prepare Ingredients

1. Bring a large pot of salted water to boil. Cook fettuccine according to package directions until al dente. Reserve 1/2 cup pasta water before draining.
2. In a small bowl, combine all Cajun seasoning ingredients. Pat shrimp dry and season with half of the Cajun seasoning blend, tossing to coat evenly.

Cook the Shrimp

1. Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add seasoned shrimp in a single layer and cook for 2-3 minutes per side until pink and cooked through. Remove shrimp to a plate.

Make the Sauce

1. In the same skillet, add remaining olive oil. Sauté bell pepper for 3-4 minutes until slightly softened. Add minced garlic and remaining Cajun seasoning, cook for 1 minute until fragrant.
2. Pour in white wine and let it simmer for 2 minutes to cook off alcohol. Add heavy cream and bring to a gentle simmer, stirring constantly.
3. Reduce heat to low and stir in parmesan cheese and butter until melted and smooth. If sauce is too thick, add reserved pasta water 1-2 tablespoons at a time.

Combine and Serve

1. Add the cooked pasta to the skillet and toss to coat with sauce. Return shrimp to the pan and gently fold in green onions and parsley.
2. Taste and adjust seasoning with salt, pepper, or additional Cajun seasoning as needed. Serve immediately with extra parmesan cheese if desired.

Notes

For milder heat, reduce cayenne pepper to 1/4 teaspoon. Leftover pasta can be stored in refrigerator for up to 3 days. When reheating, add a splash of cream or milk to restore creaminess. Fresh shrimp works best for this recipe.

Pro Tips for Making This Cajun Shrimp Pasta Just Right

Getting this dish perfect comes down to a few key techniques I’ve learned through plenty of kitchen experiments.

Don’t overcook the shrimp: My biggest tip is to remove them from the pan the moment they turn pink and curl slightly. They’ll finish cooking when you toss everything together, and this prevents that rubbery texture we all want to avoid.

Managing Your Heat Levels

Start with less cayenne than you think you need—you can always add more, but you can’t take it back! I typically use about 1/4 teaspoon for a mild heat that lets the other flavors shine through in this Cajun Shrimp Pasta.

My Secret Trick: Wine Reduction

After removing the shrimp, I always let the white wine bubble and reduce for about 30 seconds before adding the cream. This concentrates the flavors and prevents the sauce from being too thin. The alcohol cooks off, leaving behind amazing depth.

Pasta water is liquid gold: Save a cup of that starchy pasta cooking water before draining. If your sauce needs thinning, this is infinitely better than regular water—it helps everything cling together beautifully.

Fun Variations for Cajun Shrimp Pasta

The wonderful thing about this base recipe is how easily it adapts to different tastes and dietary needs.

Protein swaps: Chicken works beautifully—just cut it into bite-sized pieces and cook a bit longer than the shrimp. I’ve also made this Cajun Shrimp Pasta with scallops for special occasions, and andouille sausage adds amazing smoky flavor.

Vegetable additions: Bell peppers are classic, but I love adding:

• Fresh or frozen corn kernels
• Diced tomatoes for extra color
• Mushrooms for earthiness
• Baby spinach wilted in at the end

Pasta alternatives: While fettuccine is traditional, penne or rigatoni work wonderfully for holding that creamy sauce. For a lighter version, I sometimes serve this over zucchini noodles.

Perfect Pairings / What to Serve With It

This dish is rich and satisfying enough to stand alone, but I love pairing it with simple sides that complement rather than compete.

My go-to sides:

• A crisp Caesar salad cuts through the richness beautifully
• Garlic bread for sopping up every drop of sauce
• Simple steamed broccoli or green beans
• A light cucumber salad with vinaigrette

For drinks, a crisp white wine like Sauvignon Blanc or Pinot Grigio echoes the wine in the dish, while a cold beer works wonderfully for casual dinners.

Storing & Reheating

Leftovers keep well in the refrigerator for 2-3 days, though the pasta will absorb some of the sauce—which honestly isn’t a bad thing!

My quick tip for reheating: Add a splash of cream or pasta water to the pan along with your leftover Cajun Shrimp Pasta. Gently warm over medium-low heat, stirring frequently. This prevents the sauce from breaking and keeps everything creamy.

Freezing note: While possible, cream-based sauces can separate when frozen and thawed. If you want to prep ahead, I recommend making and freezing the seasoned shrimp separately, then preparing the sauce fresh.

My Workflow / Time-Saving Hacks

As a fellow tinkerer who loves efficiency, I’ve streamlined this process over many dinner rushes.

Prep everything first: This dish moves quickly once you start cooking, so having your spices mixed, shrimp peeled, and vegetables chopped makes all the difference. I often prep my Cajun seasoning blend in larger batches and store it for future use.

Smart Shopping Tips

Buy shrimp that’s already peeled and deveined if your budget allows—the time savings is worth it for busy weeknights. I always keep a bag in my freezer for spontaneous Cajun Shrimp Pasta cravings.

One-pan wonder: Using the same skillet throughout means fewer dishes and more flavor as each step builds on the last. Just make sure it’s large enough to hold everything comfortably.

The Science Behind the Flavor

What makes this dish so irresistibly delicious comes down to a few key flavor principles working together.

The Cajun spice blend creates what chefs call “flavor layering” each spice contributes something different, from smoky paprika to aromatic thyme. When these spices hit the hot oil with the shrimp, they bloom and intensify, creating complex flavors that permeate the entire dish.

The cream sauce works on multiple levels: the fat carries flavors throughout your mouth, while the slight acidity from the white wine brightens everything and prevents the richness from feeling heavy. This balance is what makes restaurant-quality Cajun Shrimp Pasta so memorable.

I was so excited when this kitchen experiment turned into one of my most-requested recipes! The combination of bold spices, tender shrimp, and creamy sauce creates something truly special without requiring any fancy techniques or hard-to-find ingredients.
