Creamy Cajun Shrimp Pasta Recipe
We're making Cajun Shrimp Pasta in the Chili Pepper Madness kitchen, my friends! Are you up for a nice, spicy pasta? I know I am! If you love Cajun Chicken Pasta, you'll love this version.
I think of all the seasoning blends in the world, a good Cajun blend is one of my very favorites. I use my own Homemade Cajun Seasoning blend, but there are some very good ones on the market today. Just search your local grocer.
Cajun seasonings can vary, but most contain the perfect blend of hot, spicy, and flavorful elements.
This is such a quick and easy pasta dish to make, done in 30 minutes or less. Pasta for dinner just got better.
Let's talk about how to make Cajun shrimp pasta, shall we?
Cajun Shrimp Pasta Ingredients
- Vegetable Oil. For cooking.
- Vegetables. Onion, jalapeno peppers, garlic. Use bell pepper for a milder dish.
- Cajun Pasta Sauce. Fire roasted tomatoes, tomato sauce, Cajun seasonings. For a spicier sauce, add in a bit of cayenne pepper to the sauce.
- Pasta Noodles. I'm using penne noodles, but you can use your favorites.
- Creamy Cajun Shrimp Pasta. Heavy cream, or use sour cream or crema for a lighter version.
- Parmesan Cheese.
- Shrimp. Peeled and deveined.
- For Garnish. Fresh chopped parsley, red pepper flakes
How to Make Cajun Shrimp Pasta - the Recipe Method
Cook down the onion, peppers, and garlic in a large pan or Dutch oven with a bit of olive oil or vegetable oil to soften, then stir in the fire roasted tomatoes, tomato sauce, and Cajun spices.
Simmer the sauce for at least 10 minutes, though you can simmer longer if you'd like to develop more flavor.
While simmering, cook the pasta noodles al dente, or to your preference. It's best to follow package instructions for the brand you are using.
While the sauce is simmering and the pasta is boiling, season and add the shrimp to a hot pan, then sear each piece a couple minutes per side.

Stir the heavy cream and parmesan cheese into the simmering sauce until nice and creamy, then toss it all together.
Boom! Done! Your Cajun shrimp pasta is ready to serve! I am so ready to dig into this, my friends! Can't wait for this spicy cream sauce.

Recipe Tips & Notes
- If you'd like to use cooked frozen shrimp instead of raw fresh shrimp, be sure to thaw them out first, then tuck them into the simmering sauce a few minutes to warm them before serving.
- Add good Cajun sausage would be a nice addition to this recipe. Consider smoked andouille sausage, or boudin for delicious Creamy Cajun Shrimp and Sausage Pasta. It's also delicious with chicken. Feel free to customize your proteins.
- Creamy = Optional. You can easily skip the heavy cream addition for a tomato-forward Cajun sauce, much like my Creole Sauce recipe.
Storage & Leftovers
Store leftover Cajun Shrimp Pasta in an airtight container in the fridge for up to 3-4 days. You can easily reheat it in gently in the microwave, or in a pot on the stove top.
I do not recommend freezing it.
That's it, my friends. I hope you enjoy my spicy Cajun shrimp pasta recipe. Let me know if you make it. I'd love to hear how it turned out for you.

Great recipe, Mike. I used jalapenos, crushed red pepper and cayenne. The kicker for me was the sour cream. Just a dollop made it nice and creamy. Who knew? With the heat from the spices and the creamy tomato sauce, my mouth was a happy camper!
This one goes into the rotation for sure. Thanx!
