Smoked Sausage Pasta For A Cozy One-Pot Dinner

This smoked sausage pasta cooks in a single deep skillet in about 35 minutes. The rotini simmers right in Cajun-spiced broth and diced tomatoes, so it soaks up flavor as it softens and releases starch that thickens the liquid. A splash of cream and a handful of Parmesan at the end turn it into a sauce that coats every spiral.

Most smoked sausage is sold fully cooked (check the package), so the work here is browning it for flavor and getting the pasta-to-liquid ratio right. The steps below give you the visual cues to watch for at each stage.

Ingredients

For the Pasta

• 1 tbsp olive oil, for cooking
• 12 oz smoked sausage, sliced into 1/4-inch rounds
• 1 small yellow onion, finely diced
• 1 medium red bell pepper, seeded and diced
• 3 cloves garlic, minced
• 2 tbsp tomato paste
• 1 tbsp Cajun seasoning
• 1/2 tsp kosher salt
• 1/4 tsp black pepper
• 2 1/2 cups chicken broth
• 1 14.5-ounce can diced tomatoes, with juices
• 12 oz uncooked rotini pasta

For Finishing

• 1/2 cup heavy cream
• 1/2 cup finely grated Parmesan cheese
• 2 tbsp chopped flat-leaf parsley, optional

Don’t drain the diced tomatoes. Their juice is part of the cooking liquid, and without it the rotini runs dry before it is tender. Use rotini or another short, sturdy shape; thin or quick-cooking pasta turns soft in the time the recipe allows.

How to Make Smoked Sausage Pasta in One Skillet

1. Heat the olive oil in a 12-inch deep skillet over medium-high heat. Add the sliced smoked sausage and cook for 4 minutes, stirring occasionally. The cut edges should be browned, and a thin layer of rendered fat should coat the skillet.

2. Reduce the heat to medium. Add the onion and bell pepper, then cook for 4 minutes, stirring often. The onion should look translucent, and the pepper should bend easily when stirred.

3. Add the garlic, tomato paste, Cajun seasoning, salt, and black pepper. Cook for 1 minute while stirring constantly. The tomato paste should turn a deeper red and smell toasted rather than raw.

4. Stir in the chicken broth and diced tomatoes. Add the rotini and press it beneath the liquid. Bring the mixture to a boil over medium-high heat, allowing about 3 minutes for the liquid to bubble steadily across the surface.

5. Reduce the heat to medium-low, cover the skillet, and simmer for 11 minutes. Stir every 3 minutes so the pasta does not stick and the pieces cook evenly. The rotini is ready when it is tender with a slight firm center and only a thin layer of liquid remains around it. If needed, cook uncovered for 1 to 2 minutes longer.

6. Stir in the heavy cream and Parmesan cheese. Cook uncovered over low heat for 2 minutes, stirring, then remove the skillet from the heat and fold in the parsley. The finished sauce should cling to the rotini instead of pooling in the bottom of the skillet.

Why the Sauce Thickens Without a Second Pot

Pasta boiled in a big pot of water sheds its starch down the drain. Here that starch stays in the skillet, and the 2 1/2 cups of broth plus the tomato juices are just enough for 12 ounces of rotini to absorb. That is why you shouldn’t add extra liquid at the start: the sauce would stay thin and the cream would have nothing to cling to.

Browning the sausage first also matters. The rendered fat carries the Cajun seasoning and toasted tomato paste through the whole dish, so the pasta tastes seasoned from the inside rather than just coated.

If the Pasta Is Still Firm or the Sauce Is Loose

Stovetops and skillets vary, so check the pan at the end of the covered simmer rather than trusting the timer alone.

• Pasta firm, skillet dry: add 1/4 cup broth, cover, and keep simmering until the rotini is tender. Next time, lower the heat slightly during the covered simmer.
• Pasta sticking to the bottom: the heat is too high or the pasta wasn’t pressed under the liquid. Scrape the bottom as you stir and turn the burner down.
• Sauce tight after resting: the rotini keeps absorbing liquid off the heat. Stir in a splash of broth or cream just before serving.

Swaps for the Sausage, Cream and Cheese

• Andouille instead of smoked sausage: use the same 12 ounces. Expect more heat and a coarser texture, so taste before adding all the Cajun seasoning.
• Vegetable broth instead of chicken broth: keep the same amount. The sauce will taste a little lighter and sweeter from the tomatoes.
• Half-and-half instead of heavy cream: expect a thinner sauce. Give it an extra minute uncovered on low heat after stirring it in.
• Pecorino Romano instead of Parmesan: expect a sharper, saltier finish, so hold back some of the kosher salt and adjust at the end.

If you like the Cajun-cream combination, the same flavors show up in this Cajun shrimp Alfredo pasta, which uses fettuccine and a richer Alfredo base.

Storing, Reheating and Prepping Ahead

Refrigerate leftovers in an airtight container within 2 hours of cooking and eat them within 3 to 4 days. The pasta absorbs most of the sauce overnight, so reheat it on the stovetop or in the microwave with a splash of broth or cream, stirring until it is steaming hot throughout (165°F).

To get ahead, slice the sausage and dice the onion and pepper up to 1 day in advance and refrigerate them in separate containers. Cook the pasta itself close to serving time for the best texture.

What to Serve with Smoked Sausage Pasta

This is a rich, creamy bowl, so pair it with something crisp or green: steamed broccoli, garlic bread, or a bright sweet vinaigrette salad to cut through the cream. For another one-pot pasta night built on tomatoes and meat, try American chop suey.
