Cajun Spaghetti Ingredients
- Sausage: You can swap the sausage for chicken, or shrimp, or leave it out altogether!
- Vegetables: You can add more veggies, such as wilted spinach or sauteed mushrooms, or whatever you like!
- Adjust the Spice: If you like extra spice, add some cayenne pepper or a few dashes of your favorite hot sauce. Or, if you like it more mild, swap the sausage out for smoked or Kielbasa sausage.
How to Make Cajun Spaghetti
I like making this pasta around Mardi Gras because it has that amazing Southern flavor! Not only is it delicious, but it’s so easy to put together, and the ingredients are pretty basic.
- Cook Pasta: Bring a large pot of water to a rolling boil. Then cook the spaghetti noodles as directed on the package. Drain and set aside. (Save some pasta water to thin the sauce later if needed.)
- Brown Sausage: Add sausage to a large skillet over medium high heat and cook for 3-4 minutes. Flip halfway through until browned on both sides. Remove from the pan and reserve.
- Cook Veggies: In the same skillet, heat olive oil over medium heat for 30 seconds. Then add diced red bell peppers and diced shallot. Cook for 2-3 minutes, until softened, then add minced garlic and cook for an additional 30 seconds.
- Combine: Stir in the tomato paste, Cajun seasoning, and flour, then slowly whisk in chicken broth.
- Whisk: Whisk in the heavy cream. Bring to a simmer and cook until it begins to thicken, about 5 minutes.
- Add: Whisk in Parmesan cheese until fully melted. Add the cooked spaghetti and browned sausage to the skillet, then toss to coat. Taste and season with salt and ground black pepper before serving your Cajun Spaghetti.
Alyssa’s Pro Tip
Sauce not thick enough? It likely needs to simmer a little longer. But remember, once you turn off the heat, it will continue to thicken.
