Ingredients Overview

Every ingredient in this one-pot Cajun pasta has a specific role in creating bold flavor and rich, creamy texture.

Smoked sausage (andouille or kielbasa)
Pre-cooked sausage adds deep, smoky flavor. Slice into rounds or half-moons for quicker browning. Andouille brings more heat, while kielbasa is milder.

Pasta (penne, rotini, or rigatoni)
Short-cut pasta works best to hold the sauce. Choose whole wheat or gluten-free if preferred.

Heavy cream
The base of the sauce. It balances the Cajun heat and adds luxurious texture.

Chicken broth
Used to cook the pasta and thin out the cream. It also adds savory depth.

Garlic and onion
Sautéed to build flavor before adding sausage and liquid.

Cajun seasoning
The heart of the recipe. Use a store-bought blend or make your own with paprika, cayenne, garlic powder, onion powder, oregano, and thyme.

Olive oil or butter
Used for sautéing and flavoring the base.

Parmesan cheese
Stirred in at the end for extra richness and umami.

Optional add-ins: bell peppers, spinach, or mushrooms for added vegetables and color.

Step-by-Step Instructions

1. Sauté the sausage (5–6 minutes)
In a large deep skillet or Dutch oven, heat 1 tbsp olive oil over medium-high heat. Add 12 oz sliced smoked sausage and cook until browned on both sides. Remove and set aside.

2. Sauté aromatics (2–3 minutes)
In the same pot, reduce heat to medium. Add 1 diced onion and 2–3 minced garlic cloves. Cook until soft and fragrant, about 2–3 minutes. Add 1 tbsp Cajun seasoning and stir to coat.

3. Add liquids and pasta (1 minute)
Pour in:
– 2½ cups chicken broth
– 1 cup heavy cream
Bring to a low boil.

4. Add pasta and cook (10–12 minutes)
Stir in 8 oz dry pasta. Reduce heat to medium-low, cover, and simmer for 10–12 minutes, stirring occasionally to prevent sticking. Add a splash of broth or water if needed.

5. Finish the sauce (2–3 minutes)
Once the pasta is tender, stir in the browned sausage and ½ cup grated Parmesan cheese. Simmer for 2–3 minutes until creamy and well combined. Adjust seasoning with salt or extra Cajun spice if desired.

6. Serve hot
Garnish with chopped parsley or a pinch of red pepper flakes for heat.

Common mistakes to avoid:
– Don’t overcook the pasta—it continues softening in the hot sauce.
– Avoid too much Cajun seasoning at first—add gradually and taste.
– Use freshly grated Parmesan for the smoothest finish.
