Cajun Shrimp Pasta is fettuccini noodles cooked al dente and tossed with Cajun-seasoned shrimp and a creamy, Cajun-seasoned sauce. If this sounds good to you, be sure to also try my Cajun Shrimp and Sausage Pasta and Cajun Jambalaya Pasta.

Cajun Shrimp Pasta

It’s all about the shrimp and creamy sauce with a kick in this recipe. Both are seasoned with Cajun seasoning for just the right amount of spice in each bite. The first time I tested the recipe, the sauce wasn’t quite creamy enough for my liking. So, after testing it a couple more times, we have a solid Cajun Shrimp Pasta recipe.

Pasta Ingredients

Pasta: Fettuccini pasta seemed to complement this dish the best. We tried some other varieties, but the size of the fettuccini worked because the noodles can handle a creamy, heavy sauce. If you are feeling motivated, make your own homemade pasta to use! Be sure to reserve about a cup of pasta water before you drain the noodles. I will explain more about that below.

Shrimp: For this recipe, I used large uncooked shrimp that was peeled, deveined, and had the tail removed. If you are buying fresh shrimp, it is up to you if you decide to devein the shrimp.

Cajun Seasoning: I added Cajun seasoning to both the shrimp and the sauce. If you don’t have any on hand, make your own Cajun seasoning. Then, you will have plenty to use for this recipe and my other Cajun recipes like Cajun Shrimp Sausage Kebabs, Cajun Chicken Macaroni and Cheese, and Cajun Chicken with Roasted Garlic Alfredo.

Heavy Cream: Heavy cream adds creaminess to the sauce. We tried substituting whole milk and were not happy with the results. However, if you don’t want the sauce quite as thick and rich, you could use a little less cream.

Steps for Making Shrimp, Onions, and then Noodles in the Sauce for Cajun Shrimp Pasta Recipe

Boiling the Noodles

The first thing to do in this recipe is to cook the noodles al dente. (Check the package instructions for the cooking time.) Once the salted water has come to a boil, cook the noodles. After they are cooked, but before draining the noodles, reserve a cup of pasta water and set it aside. Drain the rest of the water, coat them in olive oil, and set them aside.

How to Cook Shrimp

The next step in the recipe is to cook the shrimp. First, season each shrimp with Cajun seasoning, salt, and pepper. Heat up oil in a large skillet and when hot, add the seasoned shrimp. Cook the shrimp for 1-2 minutes per side. Shrimp is cooked when it is no longer gray and is firm, with a hint of pink color. Remove the cooked shrimp from the skillet and tent them to keep warm.

Why Reserve Pasta Water?

There are a few pasta recipes I have that recommend reserving pasta water for the sauce (Vodka Sauce and Spicy Gnocchi Bread Bowl). But, is it important? Yes! The pasta water is added to the sauce and cooked noodles. The starch from the pasta water also helps bind the sauce and pasta together rather than simply coating the noodles. This gives you a full-flavored taste in every bite!

Can I Use Frozen Cooked Shrimp?

Yes, you could use frozen cooked shrimp. If you do, let the shrimp thaw; then, toss them in Cajun seasoning, salt, and pepper. (You would not need the oil, since you won’t be cooking them.) Once tossed in the seasonings, add the shrimp to the sauce when you add the noodles.

How to Store Cajun Shrimp Pasta

I recommend storing it in an airtight container in the refrigerator for a few days. To reheat the dish, I highly recommend warming in a skillet on the stovetop.

    This recipe is unbelievably sooo good and easy. Would love to make this for family vacation … could I make and freeze, any suggestions

    1. I’m not sure the shrimp will hold up after freezing… but you would always add the shrimp later. 🙂
