From Start to Finish: Creamy Cajun Shrimp Pasta

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain the pasta, reserving about 1/2 cup of the pasta water, and set aside.

Step 2: Prepare the Shrimp

While the pasta cooks, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Toss the peeled and deveined shrimp with 1 tablespoon of Cajun seasoning. Add the shrimp to the skillet and cook for about 2-3 minutes per side, until pink and opaque. Remove the shrimp from the skillet and set aside.

Step 3: Sauté the Vegetables

In the same skillet, add the remaining tablespoon of olive oil. Sauté the diced onion, red bell pepper, and green bell pepper over medium heat until softened, about 4-5 minutes. Add the minced garlic and cook for an additional minute until fragrant.

Step 4: Build the Sauce

Pour in the chicken broth and heavy cream, stirring to combine. Add the remaining tablespoon of Cajun seasoning, and season with salt and pepper to taste. Let the sauce simmer gently for 5-7 minutes, allowing it to thicken slightly.

Step 5: Combine Everything

Return the cooked shrimp to the skillet, toss to coat in the sauce. Add the drained fettuccine pasta and grated Parmesan cheese. Toss everything together, adding a splash of reserved pasta water if needed to loosen the sauce.

Step 6: Garnish and Serve

Sprinkle chopped fresh parsley over the top for a burst of color and freshness. Serve immediately, and enjoy the creamy, spicy goodness!

Make It Diet-Friendly

• Swap heavy cream for coconut milk or a low-fat cream alternative to reduce calories.
• Use whole wheat or chickpea fettuccine for added fiber and nutrients.
• Reduce the amount of oil used in sautéing by opting for a non-stick pan.
• Load up with more vegetables like zucchini or spinach to bulk up the dish without extra calories.

Behind-the-Scenes Notes

This recipe is a fantastic way to enjoy the flavors of Cajun cuisine without a complicated process. The Cajun seasoning is key here—if you like extra heat, feel free to add a pinch of cayenne or some crushed red pepper flakes.

For an even richer sauce, you can stir in a little cream cheese or mascarpone at the end. However, the Parmesan provides plenty of savory depth on its own.

Make Ahead Like a Pro

This Creamy Cajun Shrimp Pasta is best enjoyed fresh, but you can prepare the components ahead of time. Cook the pasta and shrimp, then keep them refrigerated separately from the sauce. When ready to eat, gently reheat the sauce and combine with the shrimp and pasta. Add a splash of broth or cream if the sauce has thickened too much. Garnish with fresh parsley just before serving for the best presentation.

Reader Q&A

Can I use frozen shrimp for this recipe?

Absolutely! Just make sure to thaw them completely and pat dry before seasoning and cooking. This helps them sear nicely and prevents excess water from diluting the sauce.

What can I substitute for heavy cream?

You can use half-and-half combined with a bit of cornstarch to thicken, or coconut cream for a dairy-free option. Keep in mind that substitutes may slightly alter the flavor and texture of the sauce.

Is it possible to make this recipe spicier?

Definitely! Increase the Cajun seasoning amount or add fresh chopped jalapeños or cayenne pepper. Adjust to your taste, but start small so the heat doesn’t overpower the other flavors.

Can I swap shrimp for chicken?

Yes, chicken breast or thigh pieces work well with this sauce. Cook the chicken thoroughly before adding the sauce. If you’re interested in a chicken-based twist, try the Creamy Chicken Pesto Pasta for more inspiration.
