Ingredients

  • Fettuccine pasta – this thick-cut pasta is perfect for tossing with the creamy sauce. You can also use linguine, pappardelle or penne pasta, if you prefer.
  • Olive oil – or another neutral-flavored vegetable oil.
  • Cajun seasoning – I love using my homemade Cajun seasoning blend because it has the perfect balance of Cajun spice and flavor! It’s made with a combination of 9 herbs and spices including paprika, garlic powder, cayenne pepper and oregano. You can click the link to make my recipe in just 5 minutes, or purchase pre-made seasoning on the spice aisle at the grocery store.
  • Shrimp – for this recipe, I recommend a medium to large size shrimp. Any size will work, you will just have to adjust the cooking time slightly if you use small or jumbo shrimp. You will want to peel and devein the shrimp, and remove the tails, before using it in this recipe.
  • Andouille sausage – this Cajun-style sausage is spicy, flavorful and perfect in this pasta recipe! Hot smoked link sausage can also be used if you can’t find andouille sausage at your local grocery store.
  • Unsalted butter – I like to cook with unsalted butter, so that I can salt the dish to taste at the end.
  • Onion – I recommend a yellow or red onion for this recipe.
  • Bell pepper – feel free to use red or green bell peppers, or a mix of both.
  • Garlic – fresh minced garlic cloves are always recommended for the best flavor.
  • Heavy cream – this is what’s used to make the delicious, creamy sauce. I do not recommend substituting it with milk or half and half, as the sauce will be too runny.
  • Fire-roasted diced tomatoes – these tomatoes add a nice, smoky flavor to the dish. Regular diced tomatoes can be used instead, if you prefer the flavor or can’t find fire-roasted tomatoes at your local grocery store.
  • Parmesan cheese – fresh grated cheese will melt nicely into the sauce, but you can also use pre-grated cheese.
  • Fresh flat-leaf parsley – this is an optional ingredient, used to garnish the dish at the end.

Instructions

I’ve included step by step photos below to make this recipe super easy to follow at home. For the full detailed recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.

Start this recipe by cooking the pasta of your choice, according to the package instructions, until al dente. Drain the pasta and set it aside while you prepare the Cajun sauce with the shrimp and sausage.

Step 1: toss shrimp with olive oil and Cajun seasoning. Heat a large skillet, or dutch oven, on the stove over medium high heat. Add the shrimp and cook for 1-2 minutes per side. Remove the shrimp from the skillet and set them aside.

Additions and substitutions

  • Omit the sausage – if you prefer just shrimp in the pasta dish, use 1 pound shrimp and omit the andouille sausage.
  • Omit the shrimp – if you prefer just sausage and no shrimp, use 1 pound sausage and omit the shrimp.
  • Use chicken instead – not a fan of shrimp or sausage? Pound 1 pound of chicken breasts until they are 1 inch thick. Coat with 2 tablespoons Cajun seasoning. Cook the chicken in the skillet first for 4-5 minutes per side. Remove it from the pan and set aside while you prepare the rest of the recipe as instructed. Slice the chicken and add it back to the pan with the pasta at the end.
  • Add more veggies – feel free to throw sliced zucchini or fresh spinach leaves in with the bell peppers and onions.
  • Add more heat – to make it even spicier, add a sliced jalapeno in with the bell peppers, or add 1/2 teaspoon cayenne pepper to the sauce with the Cajun seasoning.

Pro tips

  • If using frozen shrimp, be sure to thaw the shrimp before using it in this recipe. Thaw the shrimp overnight in the refrigerator. Or for a quick thaw, place the shrimp in a colander in the sink and run under cold water for 2-3 minutes, or until thawed.
  • Store leftovers of the cajun shrimp pasta in the refrigerator, sealed in an airtight container for up to 3 days. Reheat in a skillet on the stove over medium heat for 8-10 minutes, or until heated through.
  • If using store-bought Cajun seasoning, I recommend tasting the sauce first before adding any cayenne pepper or additional salt to the recipe. Some seasoning mixes contain more salt than others, so I always recommend tasting, then salting to your taste preference. The same goes for spice. Each seasoning mix will have a different spice level, so try the sauce first and then decide if you want to add some more spice.

Diet variations

  • To make this recipe gluten free, use a gluten-free fettuccine pasta. Always make sure the Cajun seasoning and Andouille sausage used in the recipe are also gluten free.
  • To make the recipe vegetarian, omit the sausage and shrimp. Instead add an additional pound of veggies and cook them with the bell peppers and onions. These veggies could be broccoli or cauliflower florets, sliced mushrooms or zucchinis, spinach leaves, or more sliced bell peppers.

What to serve with it

Serve this creamy Cajun shrimp pasta recipe with a baguette or bread on the side for dipping up any extra creamy Cajun sauce! It’s also great paired with a side salad. Try it with any of these bread or salad recipes.
