Ingredients

  

For the Cajun Seasoning

• 2 tsp smoked paprika
• 1.5 tsp garlic powder
• 1 tsp onion powder
• 1 tsp dried thyme
• 1/2 tsp dried oregano
• 1/2 tsp cayenne pepper or more, to taste
• 1 tsp black pepper freshly ground
• 1 tsp salt

For the Pasta and Shrimp

• 1 lb large shrimp peeled and deveined, tails on or off
• 1 tbsp olive oil
• 12 oz fettuccine pasta or linguine

For the Creamy Cajun Sauce

• 2 tbsp unsalted butter
• 1 small yellow onion finely chopped
• 1 red bell pepper chopped
• 4 cloves garlic minced
• 2 tbsp all-purpose flour
• 1 cup chicken broth low sodium
• 1 can (14.5 oz) diced tomatoes undrained
• 1 cup heavy cream
• 1/2 cup Parmesan cheese freshly grated, plus more for serving
• 2 tbsp fresh parsley chopped, for garnish
• 2 tbsp green onions sliced, for garnish

Equipment

• Large Skillet or Sauté Pan
• Large Pot
• Colander
• Small Mixing Bowl

Method

 

• In a small bowl, combine all ingredients for the Cajun seasoning (smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne, black pepper, and salt). Mix well. Pat the shrimp dry with a paper towel. Bring a large pot of heavily salted water to a boil for the pasta.
• Add the fettuccine to the boiling water and cook according to package directions until al dente. Just before draining, reserve about 1 cup of the starchy pasta water. Drain the pasta and set aside.
• While the pasta is cooking, heat the olive oil in a large skillet or sauté pan over medium-high heat. Season the shrimp with 1 tablespoon of the homemade Cajun seasoning. Add the shrimp to the hot skillet in a single layer and cook for 1-2 minutes per side, until pink and opaque. Do not overcrowd the pan; cook in batches if necessary. Remove the shrimp from the skillet and set aside.
• In the same skillet, reduce the heat to medium. Add the butter and let it melt. Add the chopped onion and red bell pepper and cook, stirring occasionally, for 5-7 minutes until softened. Add the minced garlic and cook for another minute until fragrant.
• Sprinkle the flour and the remaining Cajun seasoning over the vegetables. Stir constantly for 1 minute to cook out the raw flour taste and toast the spices.
• Slowly pour in the chicken broth while whisking continuously to prevent lumps. Stir in the undrained diced tomatoes and the heavy cream. Bring the sauce to a gentle simmer and cook for 3-5 minutes, stirring occasionally, until it has thickened slightly.
• Reduce the heat to low and stir in the grated Parmesan cheese until it’s completely melted and the sauce is smooth and creamy. Taste and adjust salt and pepper if needed.
• Return the cooked shrimp to the skillet. Add the drained pasta and toss everything together to coat the pasta evenly with the sauce. If the sauce seems too thick, add a splash of the reserved pasta water to reach your desired consistency.
• Serve immediately, garnished with fresh parsley, sliced green onions, and extra Parmesan cheese.

Notes

Spice Level: For a milder dish, reduce the cayenne pepper to 1/4 tsp. For extra heat, increase it or add a pinch of red pepper flakes with the garlic.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of milk or broth to loosen the sauce as needed.
Shrimp Tip: Be careful not to overcook the shrimp in the initial step, as they will cook a little more when returned to the hot sauce.

Pro Tips for Making This Cajun Shrimp Pasta

Over the years, I’ve learned a few things that take this dish from good to great. Here are some of my favorite tips to help you get the most flavorful results.

• Don’t Overcook the Shrimp: Shrimp cook in just a few minutes! Cook them until they are just pink and opaque. They’ll finish cooking in the warm sauce, which keeps them tender and juicy.
• Save Your Pasta Water: Before you drain your fettuccine, scoop out about a cup of the starchy water. This liquid gold is perfect for thinning the sauce if it gets too thick, and the starch helps the sauce cling beautifully to the pasta.
• Use Freshly Grated Parmesan: It makes all the difference! Pre-shredded cheese often has anti-caking agents that can make your sauce grainy. Freshly grated Parmesan will melt into a silky-smooth sauce for your Cajun Shrimp Pasta.
• My Secret Trick: I always bloom the Cajun spices in the butter and oil for about 30 seconds before adding the other ingredients. This little step toasts the spices, deepening their flavor and unlocking their incredible aroma. It’s a small detail that adds so much depth!

Fun Variations for Cajun Shrimp Pasta

One of the things I love most about cooking is making a recipe my own. Here are a few fun ways to put your own spin on this Cajun Shrimp Pasta.

• Add Smoked Sausage: For an extra layer of smoky flavor, add sliced andouille or smoked sausage. Sauté it before you cook the shrimp and add it back into the sauce at the end.
• Stir in Some Greens: To add a touch of freshness and color, stir in a few handfuls of fresh spinach at the end of cooking. Let it wilt into the sauce for just a minute or two.
• Change Up the Pasta: While I love fettuccine, this sauce is amazing with other pasta shapes too! Try penne, linguine, or even some cheese-filled Stuffed Shells.
• Make it Extra Cheesy: If your family loves cheese as much as mine does, feel free to stir in a little cream cheese with the heavy cream for an even richer, tangier sauce.

What to Serve With Cajun Shrimp Pasta

This Cajun Shrimp Pasta is a fantastic all-in-one meal, but a simple side can round it out beautifully. A crisp green salad with a light vinaigrette is perfect for cutting through the richness of the cream sauce. My family also loves a side of warm, crusty garlic bread for sopping up every last bit of that delicious sauce. For a green vegetable, simple roasted asparagus or steamed broccoli works wonderfully.

How to Store Cajun Shrimp Pasta

Leftovers are one of my favorite parts of cooking a big, comforting meal! To store your Cajun Shrimp Pasta, let it cool completely and then place it in an airtight container in the refrigerator for up to 3 days.

When you’re ready to reheat, I recommend doing it gently on the stovetop over low heat. Add a splash of chicken broth or milk to help loosen the sauce and bring back its creamy consistency. This helps the pasta taste almost as good as it did on day one!

Nutritional Benefits

This dish is a wonderful source of protein from the shrimp, making this Cajun Shrimp Pasta a satisfying and hearty meal for the whole family. It’s the kind of comforting dinner that fills you up and leaves everyone happy at the table.

FAQs

Can I make this dish less spicy?

Absolutely! The heat comes from the cayenne pepper in the Cajun seasoning. Simply reduce the amount or omit it entirely for a milder, but still incredibly flavorful, Cajun Shrimp Pasta.

What kind of shrimp should I use?

I recommend using large or jumbo shrimp that have been peeled and deveined. This saves you prep time and ensures you get a nice, meaty bite of shrimp with your pasta.

Can I use a different type of pasta?

Of course! While fettuccine is classic, this creamy sauce pairs beautifully with almost any pasta. Penne, linguine, or even bow ties would be delicious alternatives for this Cajun Shrimp Pasta.

Can I use milk instead of heavy cream?

You can, but the sauce won’t be as rich or thick. If using milk, I suggest creating a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) and adding it to the sauce to help it thicken.

Conclusion

There’s nothing quite like gathering the family around the table for a warm, comforting meal, and this Cajun Shrimp Pasta is one of those recipes that always feels special. It’s proof that you don’t need a lot of time or stress to create a dish that’s bursting with flavor. If you’re looking for other cozy pasta dishes, you might also love my Parmesan Chicken Pasta.
