Why you’ll love this recipe
- Restaurant quality but dare I say better ..
- Ready in under 30 minutes.
- Succulent shrimp and savory sausage tossed in creamy cajun sauce.
Shrimp: fresh or frozen?
While fresh is always the best option, I like using large, deveined, peeled frozen shrimp to save on time and did you know that the majority of the time the shrimp you get behind the counter at the grocery store was previously frozen as well?
Alternatively, you can use pre-cooked shrimp. Coat it in the Cajun seasoning and use the pan to heat it without overcooking and set aside until the end when you combine the creamy Cajun pasta dish.
Shrimp is a delicious, easy and a low-fat way to add tons of protein to any dish. I love it in creamy coconut shrimp curry and arir fryer shrimp tacos for quick and easy weeknight meals.
Ingredients and Substitutions:
These are the main ingredients for this cajun shrimp pasta. See the recipe card below for the full ingredients list and instructions.
- Sausage: this recipe calls for Roasted Red Bell Pepper and Garlic Chicken Sausage. Switch out for any flavor sausage, smoked sausage or andouille sausage are my favorite options!
- Shrimp: fresh shrimp or frozen work fine. Opt for large shrimp.
- Bowtie Pasta: any preferred noodle works as well as gluten-free.
- Cajun Seasoning: you can use your favorite creole seasoning or make this homemade Cajun seasoning which is sugar-free and delicious. If using store-bought you may need to use less seasoning as they tend to be extra salty.
- Half and Half: can be substituted for whole milk or heavy cream to keep the sauce nice and thick.
- Noodles: you can use any shape, size, and type of pasta you want. Use linguine of fettuccini for an alfredo pasta feel or penne pasta which fills with the sauce.
Variations
- Add any vegetables your heart desires to this pasta!
- Choose different sausage flavors to change it up.
Dietary Modifications
- To make this gluten-free use gluten-free noodles like Banza.
- This is a pretty dairy-heavy recipe and swaps will result in a different taste and texture.
How to make this Cajun Shrimp Pasta with Sausage (a visual step-by-step guide):
Step 1: Prep your shrimp and Cajun seasoning
Prep your frozen shrimp by placing it in a bowl of lukewarm water to defrost. In a small bowl mix together all Cajun seasonings and set aside.
Step 2: Boil off the pasta
Boil a large pot of water and cook your bowtie pasta according to the package instructions. When draining the pasta I like to leave a little pasta water in as I add it to the pasta sauce to keep the sauce creamy.
Step 3: Sauté the shrimp
While the pasta boils add 1 Tbsp. of oil to a large skillet over medium-high heat. Add 1 Tbsp. Sugar-free Cajun seasoning to the bowl of raw shrimp and mix together well. Chop your sausage into bite-size pieces.
Add the shrimp to the hot pan and sear on one side for a few minutes (image 1).
Flip and add the sausage. Cook until the shrimp is no longer translucent and fully cooked (image 2). Remove the shrimp and sausage from the pan and set aside.
Step 4: Make the spicy alfredo sauce
In the same pan you cooked the shrimp and sausage add in 2 Tbsp. of butter. Once the butter has melted add garlic and simmer until you begin to smell the garlic (image 3).
Add 2 Tbsp. flour and stir until you have a thick paste or roux scraping up all the browned bits from the bottom of the pan (image 4).
Slowly add the half and half a little as a time to the roux and whisk until the flour is no longer chunky and the sauce begins to thicken. This takes approximately 5 minutes (image 5). Remove from the heat.
Add 1 Tbsp. Cajun seasoning to the sauce and stir together well. Sprinkle 1/4 cup of cheese in the sauce and mix together well (image 6).
Step 5: Mix together to combine
Add the cooked and drained noodles to the sauce and mix together to evenly coat (image 7). I like to keep a small amount of water in the pasta so that it keeps the sauce creamy.
Add the shrimp and sausage directly to the pasta and mix together well to coat (image 8).
Step 6: Serve and enjoy!
Serve topped with chopped parsley, freshly grated parmesan cheese or red pepper flakes for an extra little kick. Add a side salad or Broccoli Crunch Salad for some greens.
Expert Tip!
Make a double batch of cajun seasoning for all our other Cajun favorites, like Cajun Chicken and Broccoli Alfredo, Cajun Steak Bites and Cajun Salmon Pasta.
