Ingredients You Need

Pasta

12 ounces short pasta
- Penne, rigatoni, rotini, or shells hold the sauce well.
- Use whole wheat or chickpea pasta if you want extra fiber or protein.

Sausage and aromatics

12 to 14 ounces smoked sausage or andouille, sliced into coins
- Andouille gives stronger spice and smoke.
- Use turkey sausage for a lighter option.
1 tablespoon olive oil
1 small yellow onion, finely diced
3 to 4 garlic cloves, minced
1 small red bell pepper, diced
1 small green bell pepper, diced
- Frozen pepper strips work in a pinch and save chopping time.

Cajun cream sauce

2 to 3 tablespoons Cajun seasoning
- Use a low sodium blend if you watch salt.
- Popular store brands work well, or use homemade if you keep it on hand.
1 teaspoon smoked paprika
1 teaspoon dried oregano
1 teaspoon dried thyme
1 teaspoon sugar
- This balances acidity and heat without making the sauce sweet.
1 cup low sodium chicken broth
1 cup heavy cream
- Use half and half for a lighter sauce, but the texture turns slightly thinner.
1 can (14.5 ounces) fire roasted diced tomatoes, undrained
- Regular diced tomatoes also work, but fire roasted add nice depth.
1 teaspoon hot sauce, optional
Salt and black pepper to taste

Cheese and finishers

1 cup freshly grated Parmesan cheese
- Freshly grated melts smoother than pre shredded.
2 tablespoons cream cheese, room temperature, optional
- This adds extra creaminess and helps the sauce cling to the pasta.
2 tablespoons chopped fresh parsley or green onions
Lemon wedges for serving, optional

Equipment

Large pot for boiling pasta
Large deep skillet or sauté pan
Colander
Wooden spoon or spatula
Chef’s knife and cutting board
Measuring cups and spoons

Quick Tips & substitutions

Salt the pasta water generously so the noodles carry flavor before they hit the sauce.

Stir in a handful of spinach or kale at the end for extra veggies.

Keep a little pasta water on the side to thin the sauce if it thickens too much.

How to Make Creamy Cajun Sausage Pasta Recipe

Step 1: Boil the pasta

Bring a large pot of salted water to a strong boil. Add the pasta and cook until al dente, usually 1 to 2 minutes less than the package suggests. Reserve about 1 cup of pasta water, then drain the pasta and set it aside.

Step 2: Brown the sausage

Heat the olive oil in a large deep skillet over medium high heat. Add the sliced sausage in a single layer and cook until browned on one side, about 3 to 4 minutes. Flip the slices and cook another 2 to 3 minutes, then transfer the sausage to a plate and keep it nearby.

Step 3: Sauté the veggies

In the same skillet, keep the sausage drippings and adjust the heat to medium. Add the onion and bell peppers and cook until they soften and turn slightly golden, about 5 to 7 minutes. Stir in the garlic and cook about 30 seconds, just until it smells fragrant.

Step 4: Build the Cajun sauce base

Sprinkle the Cajun seasoning, smoked paprika, oregano, thyme, and sugar over the veggies. Stir well so the spices coat everything and toast for about 30 seconds. Pour in the chicken broth and scrape the bottom of the pan to lift any browned bits.

Step 5: Add tomatoes and cream

Pour in the diced tomatoes with their juices and stir to combine. Add the heavy cream and hot sauce if you use it, then stir again. Bring the mixture to a gentle simmer and let it bubble for 4 to 5 minutes so it thickens slightly.

Step 6: Melt in the cheese

Lower the heat to medium low. Stir in the Parmesan and cream cheese until they melt and the sauce turns smooth and glossy. Taste and adjust with salt and black pepper as needed.

Step 7: Combine pasta and sausage

Return the browned sausage and any juices from the plate to the skillet. Add the cooked pasta and toss everything together so the sauce coats every piece. If the sauce looks too thick, splash in a little reserved pasta water until it reaches your ideal consistency.

Step 8: Finish and serve

Turn off the heat and stir in the chopped parsley or green onions. Squeeze a little lemon over the top if you like a bright finish. Serve the Creamy Cajun Sausage Pasta Recipe hot, with extra Parmesan on the side.
