Quick and Easy for Busy Weeknights

With its simple preparation and cooking process, Cajun Shrimp Pasta is an ideal choice for easy weeknight meals. In just a few steps, you can have a satisfying dinner ready on the table in no time.

Since there is little measuring and no chopping, the entire recipe can pretty much be cooked in the amount of time it takes to cook the pasta. That means that in 10-15 minutes, you can have a complete dinner.

By following the package instructions for cooking the pasta and sautéing the shrimp in a large skillet over medium-high heat, you’ll have a hearty and delicious meal without the fuss.

The Perfect Combination of Spices

Cajun Shrimp Pasta owes its distinct flavor to the harmonious blend of spices used in the dish. 

The homemade Cajun seasoning, featuring spices like smoked paprika, cayenne pepper, garlic powder, onion salt, herbs, and black pepper, imparts just the right amount of kick without overpowering the other flavors. 

This heat level can be adjusted to suit your preference, making it versatile for those who enjoy both mild and spicy food.

A Creamy Sauce That Makes a Difference

The spicy alfredo sauce is the heart and soul of this pasta dish. With ingredients like heavy cream, Parmesan cheese, and butter, the sauce becomes velvety and indulgent, enveloping the penne pasta and shrimp in a luscious coating. 

It adds depth and richness to the overall flavor profile, ensuring each bite is a delight for the senses.

Tender Shrimp

One of the highlights of this recipe is undoubtedly the succulent shrimp. The Cajun spice brings out the best in the shrimp, enhancing its natural sweetness while adding a touch of heat.

Versatility in Ingredients

Cajun Shrimp Pasta is highly adaptable to personal preferences and dietary needs. You can experiment with different types of pasta, such as whole wheat or gluten-free options, to make it even healthier. Additionally, you can incorporate colorful veggies like green and red bell peppers, diced tomatoes, or even andouille sausage to further enhance the dish’s depth of flavor.

Recipe Tip

For best results, use a Microplane cheese grater to grate the parmesan. The super fine shreds will instantly melt in the hot cream sauce.

How to Make It

  1. This recipe starts by boiling the pasta in salted water. It’s important to use a full tablespoon of salt in your pasta water because the salt will flavor the pasta. Before you drain the pasta, be sure to reserve some of the pasta water to thin out the sauce later, if needed.
  2. While the pasta is cooking, saute the shrimp. They will cook quickly over relatively high heat. You’ll remove the shrimp from the pan and set them aside and then use that same pan to make the sauce. 
  3. The cajun cream sauce is simply a mixture of heavy cream that you bring to a boil and parmesan cheese that melts in creamy smooth. There’s enough cajun seasoning ont he shrimp and in the pan to give the sauce plenty of flavor. The sauce thickens within minutes and then you simply toss everything together to serve.

Can I use a different type of pasta for Cajun Shrimp Pasta?

Yes, you can use any type of pasta you prefer, but penne pasta works well as it holds the sauce and seasonings effectively.

How spicy is Cajun Shrimp Pasta?

The spiciness can be adjusted to your taste by controlling the amount of Cajun seasoning used. It offers a flavorful kick without being overwhelmingly hot.

Can I substitute the shrimp with another protein?

Absolutely! While shrimp adds a delightful seafood element, you can substitute it with chicken, sausage, or even vegetables to suit your preferences or dietary restrictions.

Can I make Cajun Shrimp Pasta ahead of time?

It’s best to enjoy Cajun Shrimp Pasta immediately after cooking, as the creamy sauce may thicken upon refrigeration. However, you can store leftovers in an airtight container and reheat them the next day for a tasty meal.

Can I make my own Cajun seasoning?

Definitely! In fact, with this recipe, it is recommended so that you can control the amount of salt. Making your own Cajun seasoning allows you to adjust the flavors according to your preference. 

Can I make Cajun Shrimp Pasta dairy-free?

Yes, you can substitute the heavy cream and butter with dairy-free alternatives like coconut milk or cashew cream. Vegan parmesan cheese can also be used to achieve a similar flavor.

Can I add extra vegetables to Cajun Shrimp Pasta?

Yes! Feel free to add colorful vegetables such as bell peppers, diced tomatoes, or even spinach to incorporate more nutrients and textures into the dish.

Can I freeze Cajun Shrimp Pasta?

It is not recommended to freeze the dish, as the creamy sauce may separate upon thawing. It is best enjoyed fresh for the optimal taste and texture.

How can I make Cajun Shrimp Pasta less spicy?

If you prefer a milder flavor, reduce the amount of cayenne pepper or omit it entirely from the Cajun seasoning. Adjust the heat level to suit your taste preferences.

What can I serve with Cajun Shrimp Pasta?

Cajun Shrimp Pasta pairs well with a healthy green salad, steamed broccoli, or a side of crusty bread to soak up the creamy sauce. It’s a versatile dish that allows for a range of complementary sides.

Cajun Shrimp Pasta with a spicy and rich cream sauce is a quick and easy dinner recipe with just the right amount of kick!



To cook pasta:

To cook shrimp and sauce:

  • 1 pound raw shrimp deveined, cleaned, tail removed (best results if patted dry with paper towels)
  • 2 tablespoons cajun seasoning *see note below, use this quantity if making my homemade seasoning blend; may turn out too salty if using store bought
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 cup heavy cream
  • 1/2 cup parmesan cheese finely grated from a block (a microplane works best); pre-grated or not real authentic parmesan won't melt as nicely

Prior to cooking, prep all of your ingredients. You will want to add the pasta to the water around the same time you start cooking the shrimp.

  • Combine the shrimp with the Cajun seasoning and the olive oil in bowl. Toss to combine.
  • Add salt to pot of water and bring to a boil. At the same time, heat a large skillet over medium high heat.
  • Add the pasta to the salted boiling water and cook to al dente doneness. Before draining, scoop out at least 1/2 cup of the cooking water. This will be reserved to thin the sauce, if needed. Drain pasta and set aside.
  • As soon as you add the pasta to the water, add the butter to the skillet and melt. Add the seasoned shrimp in a single layer and cook until golden brown on each side, turning only once. You may have to cook shrimp in two batches to allow enough room. Once they are done cooking, transfer the cooked shrimp to a clean plate and reduce the heat to medium.
  • Add the heavy cream to the pan and scrape the bottom with a flat shaped wooden spoon to release any seasoning that stuck to the skillet. Allow the cream to bubble around the edges. Reduce the heat to low and stir in the parmesan cheese to melt.
  • Add the cooked pasta and shrimp and stir to coat. If the sauce needs to be thinned, add the reserved pasta water, one tablespoon at a time, until the desired consistency is achieved. Taste and add additional salt, if desired depending on your tastes.


  • Salt level: I highly recommend making my homemade Cajun Seasoning Mix. If you use a store bought Cajun seasoning blend, which most likely contains much more salt than I use in my blend, you should start with a small amount, taste, and continue to add to your liking. Note: because my seasoning blend is purposely less-salty, you may need to add additional salt to your serving depending on your tastes.
  • Cajun Seasoning: You can decrease the amount of spice by lowering the amount of Cayenne Pepper and/or red pepper flakes.
  • Protein variations: I often like to make this exact same recipe but with a flattened tenderized chicken breast or wild caught scallops. Both are delicious.
  • Parmesan cheese: It is highly recommended that you grate the cheese from a block using a microplane. It will melt instantly in the cream. If you have pre-grated, I recommend mincing it as fine as you can.
  • Double the recipe! You can click the 2x button and it will scale the ingredients to double the recipe. I always double it to feed my hungry family of four with leftovers to spare. My homemade Cajun mix will make 4 Tablespoons of seasoning which is the exact amount needed if you choose to double this Cajun Shrimp Pasta Recipe.

  1. Turned out way too salty and cheesy.. might have to toss out the batch or find a way to save it somehow. Also wouldn’t hurt to add some sort of veggies for a more balanced/healthy meal since it truly is just pasta + shrimp + Cajun seasoning.

    1. Did you use a store bought Cajun seasoning blend or my recipe? If you used my recipe, I’m shocked if you thought it was too salty.

  2. 5 stars
    So good! I added chopped sweet peppers, onions and sun dried tomatoes. Will definitely be making this again.

  3. 5 stars
    Love this recipe. Truly amazing. Would anyone know how much is it per serving? Like in grams or ounces, i know it can be percise.

    1. If I were to guess, each serving is probably about 12 ounces? I always double the recipe for my very hungry family of four, and that usually leaves us with a bit of leftovers.

  4. 5 stars
    Can’t rate this high enough! Found this recipe a few months ago and have made it routinely since and it’s an impressive dish to make for company. Love it.

  5. 5 stars
    Absolutely in love with this recipe! The homemade Cajun seasoning is the perfect amount of spicy. Although, there was one time when I made the mistake of putting all of the seasoning instead of the 2 Tbsp 😅, that was a fun night haha. Anyways, excellent recipe, I make it often. Thank you.

    1. Funny you say that. I always double this recipe when I make it because my family loves it so much, so the Cajun seasoning recipe is the perfect amount. I’m thinking of changing the recipe to make that more clear.

  6. 5 stars
    I used Tony Chachere’s No Salt seasoning blend. Added salt to taste. My son who loves spicy remarked he’s obsessed with the pasta! Will definitely make again. I always add a bit of lemon juice to give it a fresh taste.

  7. 5 stars
    Delicious recipe!! I made the homemade Cajun seasoning which was the perfect blend of spice for our taste and I’m so happy I made extra because we’ll be making this again soon!
