Let’s Get Cooking! Your Step-by-Step Pasta Guide
Ready for a restaurant-quality dinner made in your own kitchen? Let’s get that skillet hot!
Part 1: The Perfectly Seared Cajun Shrimp
- Season the Shrimp: In a large bowl, toss the patted-dry shrimp with the Cajun seasoning, 2 tablespoons of olive oil, and a light sprinkle of kosher salt.
- Sear in Batches: In a large, deep skillet over medium-high heat, heat 2 tablespoons of oil. Working in batches, add the shrimp in a single layer. Cook for about 1 minute per side, until browned, pink, and cooked through. Transfer the cooked shrimp to a plate and set aside. Wipe out the skillet.
Part 2: The Secret Sauce Base & Pasta
- Make the Veggie Purée: In a food processor, combine the coarsely chopped onion, bell pepper, and garlic. Pulse, scraping down the sides as needed, until a very smooth purée forms.
- Cook the Pasta: While you make the sauce, bring a large pot of heavily salted water to a boil. Cook the linguine according to package directions until al dente. Just before draining, reserve at least 1 cup of the starchy pasta water. Drain the pasta.
- Cook the Purée: In the same skillet you used for the shrimp, heat the remaining 2 tablespoons of oil over medium heat. Add the onion mixture and cook, stirring frequently, for 7 to 10 minutes. The mixture will become drier, thicker, and more concentrated in flavor.
Part 3: Assemble the Creamy Masterpiece
- Build the Cream Sauce: Add the heavy cream to the skillet with the cooked vegetable purée, scraping up any bits from the bottom of the pan. Bring the mixture to a boil, then immediately remove it from the heat.
- Melt the Cheese: Whisk the finely grated Parmesan cheese into the sauce until it is thick, smooth, and homogenous.
- Combine Everything: Add the cooked shrimp, drained pasta, fresh parsley, and chives to the skillet with the sauce. Pour in ¾ cup of the reserved pasta water.
- Toss and Serve: Stir and toss everything together over low heat until the sauce is smooth and glossy and coats every strand of pasta. If the sauce seems too thick, add more of the reserved pasta water, a tablespoon at a time, until it reaches the perfect consistency. Serve immediately, topped with more Parmesan cheese.

Notes
WiseRecipes’ Top Tips for Perfect Cajun Pasta
These simple secrets will ensure your creamy pasta is a flawless success every single time.
- Pat Your Shrimp Dry. For a perfect, golden-brown sear instead of steamed shrimp, you must pat them completely dry with paper towels before seasoning and adding them to the hot pan.
- Don’t Crowd the Pan! Searing the shrimp in batches in a single layer is the key to getting that beautiful color and flavor. Overcrowding the pan will drop the temperature and steam the shrimp.
- Pasta Water is Liquid Gold. The starchy, salty water the pasta cooked in is the professional secret to a perfect sauce. It helps the sauce emulsify and cling to the pasta, creating a glossy, smooth consistency. Never skip reserving it!
- Grate Your Own Parmesan. For the creamiest, smoothest sauce that melts beautifully, always grate your cheese from a block. Pre-shredded cheese is coated in starches that can make your sauce grainy.
- Add Cheese OFF the Heat. To prevent the cheese sauce from breaking or becoming oily, it’s best to remove the cream mixture from the direct heat before whisking in the Parmesan.
Keep It Fresh! Storing & Reheating Leftovers
This pasta is a decadent treat, and leftovers are a wonderful bonus for lunch the next day.
- Refrigerator: Once cooled, store leftovers in an airtight container in the refrigerator for up to 2 days. Seafood is best eaten fresh, and the cream sauce will thicken considerably upon chilling.
- Reheating: The best way to reheat is gently in a skillet over low heat. Add a generous splash of milk, cream, or water to the pan to help loosen up the sauce and bring it back to a creamy consistency as it warms through.
FAQs: Your Cajun Shrimp Pasta Questions, Answered!
Can I make this with chicken instead of shrimp?
Absolutely! This recipe is fantastic with chicken. Cut about 1 lb of boneless, skinless chicken breasts or thighs into 1-inch pieces. Season and cook them just as you would the shrimp, ensuring they are cooked through to 165°F before setting them aside.
Is there a substitute for heavy cream to make it lighter?
You can substitute with half-and-half for a lighter version. The sauce won’t be quite as rich and thick, but it will still be delicious. I would not recommend using regular milk, as it’s more likely to curdle.
Can I make this less spicy?
Of course. The heat level comes from the Cajun seasoning. Simply reduce the amount you toss the shrimp in from 2 teaspoons to 1 teaspoon (or less) to control the spice level to your liking.
Do I really need a food processor for the vegetables?
For the smoothest, most restaurant-like sauce texture, yes, a food processor or a high-powered blender is highly recommended. If you don’t have one, you can finely mince the onion, pepper, and garlic by hand. The final sauce will be more rustic and less smooth, but still very flavorful.
