How to Prepare Creamy Cajun Shrimp Alfredo Pasta

Making this Creamy Cajun Shrimp Alfredo Pasta is simpler than it sounds. The best part? It’s a quick and easy recipe that doesn’t require fancy ingredients or complicated techniques. With just one large skillet and a pot for your pasta, you’ll have dinner ready in under 30 minutes. Whether you’re cooking for yourself, your family, or guests, this dish never fails to impress.

Step-by-Step Instructions:

Step 1: Boil the Pasta

Begin by boiling a large pot of salted water. Add the fettuccine pasta (or your preferred variety) and cook according to the package directions until al dente. This usually takes about 8–10 minutes. Once cooked, drain the pasta and set it aside. To prevent sticking, you can toss it lightly with a touch of olive oil.

Step 2: Season and Cook the Shrimp

Place your peeled and deveined shrimp in a bowl. Pat them dry with paper towels to remove any excess moisture. Season them generously with Cajun seasoning—this is what gives the dish its signature bold flavor. Toss well to coat each shrimp evenly.

In a large skillet, heat 1 tablespoon of olive oil and 1 tablespoon of butter over medium-high heat. Once hot, add the seasoned shrimp in a single layer. Cook for about 2–3 minutes per side until the shrimp turn pink and are fully cooked. Be careful not to overcook them—they can become rubbery if left too long.

Once cooked, transfer the shrimp to a clean plate and set aside.

Step 3: Make the Alfredo Sauce

In the same skillet (do not wipe it clean), reduce the heat to medium. Add the remaining tablespoon of olive oil if needed, then stir in the minced garlic. Cook for about 30 seconds, just until fragrant.

Pour in the heavy cream and bring it to a gentle simmer, stirring frequently. Let it cook for 2–3 minutes to slightly thicken. Now, add the grated Parmesan cheese and stir continuously until melted and the sauce becomes smooth and creamy. Season the sauce with salt and black pepper to taste. If you’d like a bit more heat, sprinkle in a pinch of red pepper flakes.

Step 4: Combine the Pasta and Sauce

Add the drained pasta to the skillet with the Alfredo sauce. Toss everything together until the pasta is fully coated and the sauce clings to each strand. If the sauce is too thick, you can add a splash of the reserved pasta water to loosen it up.

Step 5: Return the Shrimp to the Pan

Gently add the cooked shrimp back into the pan. Stir everything to combine, making sure the shrimp are nestled into the pasta and warmed through. Let the whole mixture sit over low heat for a minute or two so the flavors meld together.

Step 6: Garnish and Serve

Remove the skillet from the heat. Sprinkle chopped fresh parsley on top for color and freshness. Serve the pasta hot, straight from the skillet or plated individually. If desired, offer extra Parmesan cheese and red pepper flakes on the side.

Frequently Asked Questions (FAQs)

Can I use frozen shrimp for this recipe?
Yes, frozen shrimp work perfectly for this dish. Just make sure to thaw them completely before cooking, and pat them dry with a paper towel to avoid excess water in the pan.

What type of pasta works best?
Fettuccine is the traditional choice for Alfredo-style sauces, but you can use any pasta you like. Penne, linguine, or spaghetti all work well and hold the creamy sauce beautifully.

How spicy is this recipe?
The spiciness depends on the Cajun seasoning you use. Some blends are milder, while others pack more heat. If you’re sensitive to spice, start with 1 tablespoon and taste as you go. You can also skip the red pepper flakes.

Can I make this dish ahead of time?
While it’s best served fresh, you can make it ahead and reheat it gently on the stove with a splash of cream or milk to restore the sauce’s texture.

How can I make this lighter?
To reduce the richness, you can use half-and-half instead of heavy cream and opt for whole wheat pasta. You can also add vegetables like spinach or zucchini to increase nutrition without losing flavor.
