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. 

Each bite offers a burst of flavor, perfectly complementing the creamy sauce and al dente pasta.

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.

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!



  • 1 tablespoon kosher salt
  • 8 ounces penne pasta
  • 1 pound raw shrimp deveined, cleaned, tail removed
  • 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


  • Add salt to pot of water and bring to a boil. Cook pasta to al dente doneness. Before draining, scoop out at least 1/2 cup of the cooking water. Drain pasta and set aside.
  • While the pasta is cooking, cook the shrimp and sauce. Combine shrimp with cajun seasoning and olive oil in bowl. Toss to combine.
  • Heat large skillet over medium high heat. Add butter and melt. Add 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 done cooking, transfer cooked shrimp to a clean plate and reduce heat to medium low.
  • Add heavy cream to pan and scrape bottoms to release any food that is stuck to the bottom. Allow cream to bubble. Reduce heat to low and stir in parmesan cheese to melt. Add cooked pasta and shrimp and stir to coat. If sauce needs to be thinned, add pasta water, one tablespoon at a time, until desired consistency is achieved.

I’ve had a few viewers comment that this recipe turned out too salty. If you use my homemade cajun seasoning (link below), then it will turn out perfectly delicious. 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.

    Made this using your homemade Cajun seasoning. Absolutely amazing. Wife loved it, took some to the in-laws and they loved it. Only downside is I should have made more

  2. 5 stars
    Made it almost exactly as written including the Cajun season.. I added an extra tablespoon of butter at the end in addition to the some saved pasta water to thin. Very easy meal to make and the spiciness was perfect! This is a keeper!

  3. Absolutely love it! Being from Maryland however, I made it with Old Bay. To reduce the sodium I used 1 Tbsp regular Old Bay and 1 Tbsp reduced sodium Old Bay. I have googled this recipe whenever I want to make it but yours is the quickest and easiest. I have now bookmarked it. I also make it with chicken.

  4. 4 stars
    My wife made this recipe following the recipe to the letter, and it was just a little too salty. I made it using chicken tenders instead of shrimp and used onion powder with kosher salt, and it was perfect. There’s probably a big difference of “saltiness” between brands of onion salt

  5. This recipe was so good! I appreciated the simplicity and my hubby (who is very hard to please) loved it!

    1. Yes I made this recipe and I added more Cajun seasoning than you had on there and two tablespoons more butter and about a cup and a half of the pasta liquid to the sauce and it’s perfect I don’t know why people complain about salt because it’s not salty enough for me it’s just perfect

      1. Same for me. I think anyone who complains about the salt maybe didn’t make the homemade Cajun seasoning.

  6. 5 stars
    Amazing recipe. I make the Cajun season and i put it on everything. Not just with the recipe. It perfect and has the right amount of spice.

  7. 5 stars
    This is a quick and easy recipe. I recommend using the cajun seasoning recipe embedded within this recipe. A perfect combination!
