One Pot Creamy Sausage Pasta transforms simple ingredients into a mouthwatering meal that comes together in a single skillet. This dish combines spicy Italian sausage with a velvety tomato cream sauce that clings perfectly to every bite of pasta. The magic happens as the pasta cooks directly in the sauce, absorbing all those incredible flavors while releasing its starches to create a naturally thick and silky texture that restaurant chefs strive to achieve.
I've made this pasta countless times for last-minute dinner guests, and the pot is always scraped clean. My daughter, who typically avoids anything with "visible ingredients," somehow manages to devour two servings every time I make it. There's something almost magical about how such simple ingredients create such a satisfying meal.
Ingredients
- Italian sausage: Provides rich flavor and satisfying protein; sweet or hot varieties both work beautifully depending on your spice preference
- Red bell peppers: Adds sweetness, color and vitamin C; look for firm peppers with bright, shiny skin
- Onions: Creates the aromatic foundation; yellow onions work best but red or white will do in a pinch
- Garlic: Fresh cloves provide unmistakable depth; mince them finely for the best flavor distribution
- Marinara sauce: Acts as the flavor base; choose a good quality jar or make your own with crushed tomatoes and herbs
- Short tube pasta: Shapes with ridges or hollows capture the sauce perfectly; penne, rigatoni or rotini are ideal choices
- Heavy cream: Creates that luxurious silky texture; the fat content ensures your sauce won't break or separate
- Fresh basil: Brightens the rich sauce with its aromatic qualities; add at the very end to preserve its flavor
- Parmesan cheese: Adds savory depth and helps thicken the sauce; always grate your own for the best melting properties

Detailed Cooking Instructions
- Step 1:
- Prepare the flavor base: Heat a large, deep skillet over medium heat until warm, then add a splash of olive oil. Add your diced onions with a pinch of salt and cook for 3-4 minutes until they begin to soften and become translucent. The salt helps draw out moisture and sweetness from the onions, building your flavor foundation.
- Step 2:
- Develop the aromatics: Add diced red bell peppers to the softened onions and continue cooking for another 3-4 minutes until the peppers begin to soften slightly. Their natural sweetness will start to develop as they cook down. Next, add the minced garlic and fennel seeds (if using) and cook for just 30-60 seconds until fragrant, being careful not to burn the garlic which would add bitterness.
- Step 3:
- Brown the sausage: Add the Italian sausage to the vegetable mixture, breaking it apart with a wooden spoon into small, bite-sized pieces. Cook until the sausage is no longer pink and has developed some caramelized brown bits on the bottom of the pan, about 5-7 minutes. These browned bits are flavor gold and will enrich your final sauce.
- Step 4:
- Create the sauce base: Pour in a splash of white wine (about 1/4 cup) and scrape up all those flavorful browned bits from the bottom of the pan. Let the wine reduce by half, which concentrates its flavor while cooking off the alcohol. Then add your marinara sauce and stir to combine everything thoroughly.
- Step 5:
- Cook the pasta in the sauce: Add the dry pasta directly to the sauce mixture, then pour in enough water to just cover the pasta (approximately 2-3 cups depending on your pan size). Stir gently to ensure nothing sticks to the bottom, then bring the mixture to a gentle boil. Reduce heat to maintain a steady simmer, stirring occasionally to prevent sticking.
- Step 6:
- Finish with creaminess: When the pasta is almost al dente (about 2 minutes less than package directions) and most of the liquid has been absorbed or reduced, reduce the heat to low. Stir in the heavy cream and grated Parmesan cheese, combining thoroughly until the sauce coats the back of a spoon. Allow everything to simmer gently for 1-2 minutes more until the pasta is perfectly tender.
- Step 7:
- Add final touches: Remove the skillet from heat and fold in torn fresh basil leaves, reserving some for garnish. Taste and adjust seasoning with salt, freshly ground black pepper, and red pepper flakes if desired. Let the pasta rest for 2-3 minutes before serving, which allows the sauce to thicken and cling better to the pasta.
I've discovered that using hot Italian sausage creates the perfect contrast against the creamy sauce. My husband claims he can tell when I've skipped the fennel seeds, which add that authentic Italian sausage flavor even when using a milder variety. When we have guests who can't handle spice, I use sweet Italian sausage and simply add red pepper flakes to my own portion.
The beauty of one-pot cooking lies in its beautiful simplicity. Every time I make this dish, I'm reminded of how cooking doesn't need to be complicated to be extraordinary. The way the pasta absorbs the flavors as it cooks creates an integration that's impossible to achieve when boiling pasta separately. It's a technique I've applied to countless other pasta dishes since discovering it.
This recipe has become my reliable solution for last-minute dinner guests. I can have it on the table in under 30 minutes, yet it tastes like something that simmered all afternoon. The looks of surprise and delight when people discover it's made in one pot makes the minimal effort even more satisfying.

The versatility of this dish has saved me countless times when facing a nearly-empty fridge. I've swapped chicken sausage for Italian, added leftover roasted vegetables, and even stirred in a few spoonfuls of pesto in place of the fresh basil. Each variation has been delicious in its own way, proving that a good technique can support endless creativity.
Watching the transformation from simple ingredients to a restaurant-worthy dish never ceases to amaze me. There's something deeply satisfying about the alchemy that happens in that single pot – how the starchy pasta water combines with the tomato sauce and cream to create something greater than the sum of its parts. It's cooking magic at its finest.
This One Pot Creamy Sausage Pasta has become my signature dish, the one friends text me for when they need comfort in food form. There's something almost magical about how humble ingredients transform into something so satisfying with minimal effort. In a world where we're constantly juggling responsibilities and time constraints, dishes like this remind us that nourishing ourselves and others doesn't have to be complicated or time-consuming. It just needs to be made with attention and care – and maybe a splash of cream for good measure.
