Cajun Garlic Shrimp Fettuccine Alfredo Tips, FAQ & printable recipe

Tips for success

To achieve the best flavor, allow the shrimp to sit with the Cajun seasoning for about ten minutes before searing. This gives the spices time to adhere to the surface and penetrate the meat.

If you prefer a bit more heat, add a pinch of cayenne pepper to the sauce, but be cautious as Cajun seasoning blends often already contain significant amounts of red pepper and salt.

When tossing the pasta with the sauce, do it over very low heat or off the heat entirely. This prevents the sauce from reducing too much and becoming heavy or greasy.

If you are serving a crowd, prepare the sauce in a larger skillet than you think you need, as it provides more room to toss the ingredients without spilling or breaking the delicate noodles.

Variations

• Cajun Chicken Alfredo: Replace the shrimp with thinly sliced chicken breasts. Sear the chicken in the same Cajun seasoning until golden brown and cooked to an internal temperature of 165°F (74°C) before proceeding with the sauce steps.
• Vegetable Cajun Pasta: Add sautéed bell peppers and onions to the skillet along with the garlic. These vegetables add sweetness and texture that complement the spicy Cajun seasoning and the rich Alfredo sauce perfectly.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days. Ensure the food cools to room temperature for no more than 2 hours before refrigerating.

Freezer

Freezing is not recommended as the creamy sauce may separate and the pasta texture will become mushy upon thawing and reheating.

Reheat

Reheat gently in a skillet over low heat, adding a splash of water or cream to revive the sauce consistency until heated through.

Store any leftovers in an airtight container in the refrigerator. The pasta will continue to absorb the sauce as it sits, so it may appear slightly drier when reheated.

If this happens, add a tablespoon of water or cream when warming it up to restore the creamy texture. Consume leftovers within three days for the best quality.

The sauce can be made ahead of time, but it is best to prepare the pasta and sear the shrimp just before serving. If you must make it ahead, store the sauce and the pasta separately. When ready to eat, heat the sauce in a skillet, add the pasta and shrimp, and toss until everything is hot and well-combined.

Serving ideas

Serve this dish in shallow, wide bowls to showcase the beautiful contrast between the blackened shrimp and the creamy white sauce.

A side of crusty bread or a simple green salad with a light vinaigrette pairs wonderfully with the richness of the pasta, providing a crisp counterpoint to the creamy flavors and helping to soak up any remaining sauce on the plate.

For a professional touch, garnish each serving with a sprinkle of fresh parsley right before it hits the table. The fresh herb adds a pop of color and a touch of brightness that cuts through the intensity of the Cajun spices. Serve immediately while the sauce is at its peak silkiness, as it will thicken as it cools.

Cajun Garlic Shrimp Fettuccine Alfredo

Prep 15 minCook 20 minTotal 35 minServes 4

Ingredients

• 1 lb fettuccine pasta
• 1 lb large shrimp, peeled and deveined
• 2 tbsp Cajun seasoning
• 4 cloves garlic, minced

Instructions

1. Bring a large pot of salted water to a rolling boil. Add the fettuccine and cook according to package directions until al dente. Drain the pasta, reserving a small amount of the starchy cooking water for later use if needed to adjust the sauce consistency.
2. While the pasta cooks, toss the shrimp in a bowl with the Cajun seasoning until evenly coated. Heat a large skillet over medium-high heat. Add the seasoned shrimp in a single layer and sear until opaque and pink. Ensure the internal temperature reaches 145°F (63°C). Remove from the skillet and set aside.
3. In the same skillet used for the shrimp, add the minced garlic and sauté until fragrant, about one minute. Incorporate the creamy sauce components and bring to a gentle simmer. Reduce the heat and stir until the sauce becomes smooth and thickened.
4. Add the cooked fettuccine and the seared shrimp into the skillet with the sauce. Toss everything together using tongs until the noodles are thoroughly coated in the creamy mixture. Serve immediately while hot, ensuring each portion receives an even amount of shrimp and sauce.
