Ingredients for Cajun Shrimp Pasta

For the Homemade Cajun Seasoning (Makes Approximately 4 tbsp)

• 3 teaspoons paprika
• 1 teaspoon salt
• 2 teaspoons garlic powder
• 1 teaspoon black pepper
• 1 teaspoon onion powder
• 1 teaspoon dried oregano
• 1 teaspoon cayenne pepper (adjust to your spice preference)
• 1 teaspoon dried thyme

You can use store-bought Cajun seasoning, but I find making my own allows me to control the heat level, which is great when cooking for my kids.

Plus, these are all spices you probably already have in your pantry!

For the Pasta

• 1 lb penne pasta (or pasta of choice)
• 1 lb shrimp (fresh or frozen, peeled and deveined)
• 1 tablespoon olive oil
• 2 tablespoons Cajun seasoning (divided)
• 3 tablespoons unsalted butter
• 3 cloves garlic (minced)
• 14 ounce can diced tomatoes
• 1½ cups heavy whipping cream
• ½ cup parmesan cheese (grated)

For Garnish

• Extra parmesan cheese (grated)
• 2 tablespoons fresh parsley (chopped)

How to Make Cajun Shrimp Pasta

Prepare the Shrimp and Pasta

1. If using frozen shrimp, thaw them first by running cold water over them, or let them thaw in the fridge.
2. While preparing the shrimp and sauce, cook the pasta according to package instructions until al dente. Be sure to salt your pasta water – it should taste like the sea! Drain when finished but reserve 1 cup of pasta water in case you need to adjust the sauce thickness later.
3. Toss the shrimp with half of the Cajun seasoning (1 tablespoon). In a deep skillet or pan, heat the olive oil over medium heat. Add the seasoned shrimp in a single layer and cook for about 1-2 minutes per side. You’ll know they’re done when they turn pink and are no longer translucent. Remove the shrimp from the pan and cover to keep warm.

Make the Creamy Cajun Sauce

4. Using the same pan (don’t wipe it clean – those flavors are gold!), add the butter, minced garlic, and remaining Cajun seasoning. Cook for about 1 minute until the butter is completely melted and the garlic becomes fragrant.
5. Add the diced tomatoes and sauté for 1-2 minutes, allowing them to mingle with the spices.
6. Reduce heat to low. Slowly pour in the heavy cream while stirring continuously to create a smooth sauce. This gradual approach prevents the cream from separating.
7. Add the parmesan cheese and let the sauce simmer gently until it thickens slightly. If it gets too thick, you can add a splash of the reserved pasta water to reach your desired consistency.

Combine and Serve

8. Return the cooked shrimp to the pan and add the drained pasta. Gently toss until all the pasta is evenly coated with the creamy sauce.
9. Garnish with additional grated parmesan cheese and freshly chopped parsley. The bright green parsley not only adds a pop of color but also a fresh flavor that balances the rich, spicy sauce.
10. Serve immediately for the best flavor and texture!

Tips for Perfect Cajun Shrimp Pasta

Don’t overcook the shrimp – Shrimp cook very quickly and can become rubbery if left too long. Once they turn pink and curl slightly, they’re done.

Adjust the spice level – The beauty of making your own Cajun seasoning is controlling the heat. For milder flavor, reduce the cayenne pepper. For extra kick, add a bit more!

Room temperature cream – If possible, let your heavy cream come to room temperature before adding it to the hot pan. This reduces the chance of it curdling when it hits the hot mixture.

Save some pasta water – The starchy pasta water is perfect for adjusting the consistency of your sauce. Too thick? Add a splash. Too thin? Let it simmer a little longer.

Variations for This Spicy Shrimp Pasta

Add vegetables – Bell peppers, onions, and celery (the “holy trinity” of Cajun cooking) make excellent additions. Slice them thin and sauté them just after cooking the shrimp.

Try different proteins – This sauce works beautifully with chicken, andouille sausage, or even a combination for a hearty jambalaya-inspired pasta.

Make it lighter – For a less rich version, substitute half-and-half for some or all of the heavy cream. The sauce won’t be quite as thick but will still be delicious.

Gluten-free option – Simply swap in your favorite gluten-free pasta to make this dish accessible for everyone at your table.

What to Serve with Cajun Shrimp Pasta

This dish shines as a complete meal on its own, but if you’re looking to round out your dinner, here are some perfect companions:

• Garlic Butter Chicken Bites – For those who might prefer chicken over shrimp
• A simple green salad with a light vinaigrette to balance the richness
• Crusty garlic bread for sopping up every last drop of that amazing sauce
• Air Fryer Shrimp – For extra shrimp lovers!

Storing and Reheating Your Cajun Pasta

If you happen to have leftovers (we rarely do at our house!), store them in an airtight container in the refrigerator for up to 2 days.

To reheat, add a splash of cream or milk to a pan, then gently warm the pasta over medium-low heat, stirring occasionally.

Microwaving works in a pinch, but the stovetop method helps maintain the sauce’s creamy texture better.

I don’t recommend freezing this dish as the cream sauce can separate and the pasta texture suffers when thawed.
