How to Make Cajun Sausage Spaghetti

Cook pasta al dente in a large pot according to package directions, drain, and set aside.

Melt 1 tablespoon of butter in a large skillet on medium-high heat. Once melted, add sliced Sausage and saute for approximately 3 minutes or until sausage starts to brown on both sides. Remove sausage from pan and set aside. I like to put a paper towel on a plate and put the sausage on the paper towel to soak up some of the butter.

Add the remaining tablespoon of butter to the bottom of the pan and melt. Add the diced bell peppers, shallot, and creole seasoning. Sautee until vegetables are just barely tender. Add minced garlic, and saute for 1 minute until fragrant.

Sprinkle flour over vegetables, and stir in flour to coat. While whisking continuously, gradually add chicken broth. Add in heavy cream and stir until combined.

Bring to a boil, whisking continuously to prevent burning. Then, turn down to medium heat and let simmer for about 5 minutes or until sauce starts to thicken.

Stir in shredded parmesan cheese until melted and fully incorporated.

Cream sauce and adding shredded parmesan to the sauce.

Stir in the cooked sausage. Add cooked pasta to the sauce and mix until it’s evenly coated and well incorporated with the sausage and vegetables.

Serve topped with additional grated parmesan and fresh parsley if desired.

FAQs

How do I store Cajun Sausage Spaghetti?

Cajun Spaghetti can be stored in an airtight container for up to 3 days. It can be reheated in the microwave until heated through. Just a heads up, creamy pasta dishes are best eaten fresh and may not reheat with the same consistency but will still taste delish!

What is Andouille sausage?

Andouille sausage is a smoky, spicy sausage that’s super popular in Cajun and Creole cooking. It’s made from pork, seasoned with garlic, pepper, and other spices, and then smoked to pack in all that bold flavor. You’ll often find it in dishes like gumbo, jambalaya, or even grilled on its own. It’s like the life of the party when it comes to sausage! 😉

Is there an Andouille sausage substitute?

If you can’t get your hands on andouille sausage or are simply not a fan of it…no worries! There are plenty of substitutes. Smoked kielbasa works excellent since it has a similar smoky vibe, or even a simple beef smoked sausage or spicy Italian sausage.. Chicken, turkey sausage, or shrimp can do the trick for a lighter option.

Other optional add-ins or variations:

Add in some mushrooms for extra flavor or swap out the spaghetti pasta for whatever you have on hand—rotini, penne, bowtie pasta, you name it. Don’t be afraid to get creative with the ingredients you love. Depending on your spice level preference, you can add less creole for a less spicy option. If you like things a little spicier, add a pinch of red pepper flakes in with your veggies when you’re sauteeing them.

This spicy Cajun pasta is the perfect 30-minute meal. It is seriously such a yummy and easy weeknight dinner. If you need another quick and easy meal, try this Easy Teriyaki Chicken Bowl.
