Step-by-Step Instructions

Step 1: Gather and Prepare Your Ingredients

Before you even turn on the stove, take a moment to organize everything you’ll need. This includes chopping, measuring, and setting aside your ingredients—commonly referred to as “mise en place” in professional kitchens. Doing this ensures a smooth cooking process and prevents missed steps later on.

You’ll need the following main ingredients:

• 1 tablespoon olive oil

• 1 pound smoked sausage (Andouille or Kielbasa), sliced into ¼-inch rounds

• 1 medium yellow onion, finely chopped

• 1 red bell pepper, thinly sliced

• 1 green bell pepper, thinly sliced

• 4 cloves garlic, minced

• 2 teaspoons Cajun seasoning (store-bought or homemade)

• ½ teaspoon smoked paprika (optional, for depth)

• ½ teaspoon salt (adjust to taste)

• ¼ teaspoon black pepper

• 2 cups chicken broth (preferably low-sodium)

• 1 cup heavy cream

• 8 ounces uncooked pasta (penne, rotini, or rigatoni work well)

• 1 cup grated Parmesan cheese

• Fresh parsley or green onions for garnish (optional)

Preparation Tips:

• Sausage: Smoked sausage is already cooked, so it mainly needs browning to bring out flavor. Slicing it evenly helps with uniform cooking.

• Vegetables: Keep vegetables similar in size to ensure even sautéing.

• Cajun seasoning: If using store-bought blends, check the salt level to avoid over-seasoning. Homemade blends are easy and customizable.

Step 2: Brown the Sausage for Maximum Flavor

Place a large, deep skillet or Dutch oven over medium-high heat. Add 1 tablespoon of olive oil and allow it to heat until shimmering.

Add the sliced sausage to the hot pan in a single layer. Let it sear for 2–3 minutes without stirring. This allows the sausage to brown and caramelize—a crucial step for developing rich flavor. Stir and continue cooking for another 2–3 minutes until the slices are evenly browned.

Why This Matters:
Browning creates the Maillard reaction—a chemical process that adds deep, umami-rich flavor to the sausage and lays the foundation for the rest of the dish. Don’t rush this step.

Once browned, use a slotted spoon to remove the sausage from the pan and set aside on a plate. Leave behind the flavorful drippings.

Step 3: Sauté the Aromatics

To the same pan with the sausage drippings, add the chopped onions and bell peppers. Cook over medium heat for about 4–5 minutes, stirring occasionally, until the vegetables begin to soften and take on a bit of color.

Add the minced garlic and cook for 30–60 seconds, just until fragrant. Stir frequently to avoid burning.

Flavor Layering Tip:
At this point, scrape the bottom of the pan with your spoon or spatula to release the fond (the browned bits stuck to the pan from the sausage). This fond holds concentrated flavor and will melt into the sauce later.

Step 4: Season and Deglaze

Once the vegetables are tender and the garlic is aromatic, sprinkle in your Cajun seasoning, smoked paprika, salt, and pepper. Stir well to coat the vegetables evenly in the spices.

Let the spices bloom in the hot oil for about 30 seconds. This quick toasting enhances the flavor intensity.

Next, pour in the chicken broth to deglaze the pan. Stir thoroughly, scraping up any remaining fond from the bottom. Let the mixture simmer for 1–2 minutes to meld the flavors.

Step 5: Add the Pasta and Cream

Add the uncooked pasta directly to the pot, followed by the heavy cream. Stir to combine everything evenly. Bring the mixture to a gentle boil over medium-high heat.

Once boiling, reduce the heat to low or medium-low to maintain a steady simmer. Cover the pot with a lid (leaving a slight crack for steam to escape) and let the pasta cook for about 12–15 minutes, stirring occasionally to prevent sticking.

Important Notes:

• Stir gently and regularly, especially near the bottom of the pot. One-pot pastas can easily burn if left untouched.

• Cooking time can vary slightly depending on the shape and brand of pasta. Test for doneness around the 12-minute mark.

Step 6: Reintroduce the Sausage and Finish the Sauce

Once the pasta is nearly tender and most of the liquid has been absorbed or thickened, return the cooked sausage to the pot. Stir well to distribute it evenly.

Sprinkle in the Parmesan cheese and stir until fully melted and the sauce becomes creamy and smooth. If the sauce is too thick, you can loosen it with a splash of warm broth or cream. If it’s too thin, simmer uncovered for an additional 1–2 minutes.

Taste and adjust seasoning with salt, pepper, or extra Cajun spice as needed.

Step 7: Rest and Garnish

Remove the pot from heat and let it rest for 2–3 minutes before serving. This allows the sauce to set slightly and cling better to the pasta.

Top with chopped fresh parsley or green onions for a burst of freshness and color, if desired. A little extra Parmesan on top never hurts.

Step 8: Serve and Enjoy

Spoon generous portions into shallow bowls. This dish is rich, creamy, and satisfying all on its own, but it pairs wonderfully with:

• A simple side salad with vinaigrette

• Buttery garlic bread or a baguette

• Roasted or steamed vegetables like broccoli or asparagus

Serve hot, and enjoy the perfect harmony of smoky, spicy, and creamy flavors.
