Ingredients
- 12-16 ounces short cut pasta such as penne (use gluten-free if needed)
- 2 Tablespoons olive oil
- 1 Tablespoon Cajun seasoning (divided)
- 12 ounces smoked andouille sausage (sliced on the bias)
- 1 medium yellow onion (diced)
- 2 bell peppers of any color (diced)
- 1 pinch red pepper flakes (to taste)
- 2 cloves garlic (minced)
- 1 1/4 cups chicken broth
- 1/2 cup heavy cream or full-fat coconut milk
- 2 Tablespoons tomato paste
- 1/2 cup grated parmesan cheese (plus more for serving)
- Fresh parsley (chopped for garnish)
Step-by-Step Instructions
- Prepare the Pasta: Bring a large pot of salted water to a boil. Cook the pasta to al dente according to the package directions. Before draining, reserve 1 cup of the pasta cooking water. Drain the pasta but do not rinse it.
- Sear the Sausage: While the pasta cooks, heat the olive oil in a large skillet (a 10-inch cast iron works best) over medium-high heat. Add the sliced sausage and 2 teaspoons of the Cajun seasoning. Cook until the sausage is crisp on both sides, which takes about 5 minutes, then transfer it to a clean plate.
- Sauté the Vegetables: Lower the heat to medium. In the same skillet, add the diced onion, bell peppers, the remaining teaspoon of Cajun seasoning, and red pepper flakes. Sauté for about 3 minutes until softened. Add the minced garlic and cook for 1 additional minute until fragrant.
- Simmer the Sauce: Whisk in the chicken broth, heavy cream, and tomato paste until the mixture is smooth. Bring it to a gentle boil, then reduce the heat to medium-low. Simmer for 5 to 7 minutes to allow the sauce to thicken slightly.
- Combine and Serve: Stir the parmesan cheese into the sauce. Add the cooked pasta and the crispy sausage back into the skillet. Toss everything together to coat. If the sauce is too thick, add the reserved pasta water a little at a time until you reach your desired consistency. Garnish with fresh parsley and extra parmesan.
Expert Tips for the Best Pasta
To achieve the best results with your Cajun Sausage Pasta, always reserve your pasta water. The starchy water is the secret to creating a silky sauce that binds perfectly to the noodles. Using a cast iron skillet is also recommended, as it provides a superior sear on the andouille sausage, adding extra smoky depth to the dish. Finally, be sure not to overcook the pasta in the boiling water; since it will simmer briefly in the sauce at the end, cooking it to al dente ensures it maintains a pleasant bite.
Variations and Substitutions
If you prefer a milder dish, you can easily tone down the spice by using a regular smoked sausage or kielbasa instead of andouille. You can also reduce the amount of Cajun seasoning or omit the red pepper flakes entirely. For those looking to add more nutrition, try tossing in a handful of fresh spinach or sliced mushrooms during the vegetable sauté step. This recipe also works well with various pasta shapes like bow tie, gemelli, or even fettuccine if you prefer a longer noodle.
Serving Suggestions
This creamy pasta pair beautifully with a crisp green salad tossed in a light vinaigrette to balance the richness of the cream sauce. A side of toasted garlic bread or crusty French bread is also perfect for soaking up any extra Cajun sauce left on the plate. For a complete Southern-inspired feast, consider serving it alongside roasted corn on the cob or steamed green beans.
Storage, Freezing, and Reheating
Allow the Cajun Sausage Pasta to reach room temperature before transferring it to an airtight container. It can be stored in the refrigerator for up to 4 days. To reheat, use the microwave or place it in a skillet over low heat on the stovetop. If the sauce has thickened too much in the fridge, add a splash of chicken broth or water while reheating to loosen it back up. Freezing is not recommended for this specific recipe, as the cream-based sauce may separate or change texture upon thawing.

Frequently Asked Questions
Can I make this recipe dairy-free?
Yes, you can substitute the heavy cream with full-fat canned coconut milk and use a dairy-free parmesan alternative or nutritional yeast to achieve a similar creamy texture.
What if I don’t have store-bought Cajun seasoning?
You can make a quick DIY blend by mixing smoked paprika, garlic powder, onion powder, dried oregano, thyme, chili powder, cayenne pepper, salt, and black pepper.
Is andouille sausage very spicy?
Andouille is a smoked sausage that typically has a moderate kick. If you are very sensitive to heat, substituting it with kielbasa or a mild chicken sausage is a great way to enjoy the flavors without the burn.
Can I use a different protein?
Absolutely. While sausage is traditional, this creamy Cajun sauce also pairs wonderfully with sautéed shrimp or blackened chicken breast.
