Ingredients

- 8 oz penne pasta
- 1 lb large shrimp, peeled and deveined
- 1 tbsp olive oil
- 2 tbsp Cajun seasoning, divided
- 2 tbsp unsalted butter
- 2 garlic cloves, minced
- 1/2 cup diced tomatoes
- 1 1/2 cups heavy whipping cream
- 1/2 cup grated parmesan cheese, plus more for serving
- 2 tbsp parsley, chopped, for garnish optional
- Salted water for boiling pasta
Instructions
- Bring a pot of salted water to a boil and cook the penne pasta until al dente according to package directions. Reserve a little pasta water, then drain the pasta and keep it warm.
- Season the shrimp with 1 tablespoon of Cajun seasoning.
- Heat the olive oil in a deep skillet over medium heat. Add the shrimp in a single layer and cook for 1 to 2 minutes per side, until no longer translucent. Remove from the skillet and keep warm.

- Pour in the heavy cream, then stir in the remaining Cajun seasoning and grated parmesan cheese.
- Bring the sauce to a gentle simmer, then reduce the heat to medium-low. Cook for 2 to 3 minutes, or until the sauce thickens slightly.
- Return the shrimp and pasta to the skillet. Toss everything together until well coated and heated through. Add a splash of reserved pasta water if needed to loosen the sauce.
- Serve the Creamy Cajun Shrimp Pasta with extra parmesan and chopped parsley if desired.

Tips & Tricks
Use large shrimp for the best texture and presentation. Avoid overcooking the shrimp, since they can turn rubbery very quickly. If your Cajun seasoning is salty or extra spicy, start with less and add more to taste. For a smoother sauce, grate your parmesan finely so it melts evenly. You can also swap penne for fettuccine, rotini, or linguine if that is what you have on hand.

FAQ
Can I use frozen shrimp?
Yes, just thaw them fully and pat them dry before seasoning and cooking.
Is Creamy Cajun Shrimp Pasta very spicy?
It depends on the Cajun seasoning you use. Some blends are mild, while others are much hotter.
Can I make this recipe ahead of time?
It is best served fresh, but you can make it ahead and reheat gently with a splash of cream or milk.
What pasta works best for this recipe?
Penne is great because it holds the creamy sauce well, but other short or long pasta shapes also work.
Can I add vegetables?
Yes, spinach, bell peppers, onions, or mushrooms all pair well with the Cajun cream sauce.
How do I keep the sauce from getting too thick?
Add a little reserved pasta water until the sauce reaches your preferred consistency.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. For freezing, place cooled pasta in a freezer-safe container for up to 1 month, though the cream sauce may separate slightly after thawing. Reheat gently on the stovetop or in the microwave with a splash of cream, milk, or water to loosen the sauce.
