How to Make One-Pot Sausage Pasta Recipe
Step 1: Brown the Sausage and Sauté the Aromatics
Start by warming the olive oil in a large nonstick pot over medium-high heat until it shimmers. Add your Italian sausage and diced sweet onion, breaking the sausage apart with a wooden spoon as it cooks. In about five minutes, the sausage will be beautifully browned and cooked through while the onions soften to sweet tenderness. Stir in minced garlic and let it cook for just 20 seconds until fragrant, then sprinkle in the dried Italian seasoning, salt, pepper, and optional red pepper flakes. At this stage, drain any excess grease for a lighter sauce without losing flavor.
Step 2: Build the Sauce Base
Next, stir in the tomato paste to the sausage mixture until every crumb is coated and the deep red color intensifies. This concentrated tomato goodness is the heart of the sauce, creating depth and a rich umami backbone that complements the sausage perfectly.
Step 3: Add Broth, Marinara, and Pasta
Pour in the chicken broth followed by the marinara sauce, then add the uncooked rigatoni right into the pot. Give everything a good stir so the pasta is fully submerged and evenly distributed. Increase the heat to bring this liquid to a lively boil. Once boiling, stir once more, cover with a lid, and reduce the heat to a gentle simmer. Let it cook undisturbed for 14 minutes, stirring a few times near the end to keep the pasta from sticking to the bottom. This step ensures the pasta absorbs those incredible flavors as it cooks to perfectly al dente texture.
Step 4: Finish with Cream and Cheese
When your pasta is tender and most of the liquid is absorbed, pour in the heavy cream and stir gently to blend it into a silky sauce. Warm through for one to two minutes, then add the freshly grated Parmesan and sliced basil leaves. Stir everything together until the cheese melts and the basil infuses its aromatic notes beautifully throughout the dish.
Step 5: Serve and Enjoy
Remove the pot from heat and dish out generous helpings into bowls. Pass around some extra freshly grated Parmesan at the table for anyone craving a cheesier finish. This One-Pot Sausage Pasta Recipe promises warm smiles and satisfied appetites all around.
How to Serve One-Pot Sausage Pasta Recipe

Garnishes
Fresh basil leaves and a sprinkle of Parmesan are classic garnishes that add visual appeal and a pop of bright flavor. For an extra touch, a drizzle of good quality olive oil or a pinch of red pepper flakes can bring complexity and depth to each bite.
Side Dishes
This hearty pasta pairs wonderfully with a crisp green salad or a simple garlic bread to sop up any lingering sauce. Roasted vegetables or steamed broccoli can provide a fresh contrast and balance the meal nicely.
Creative Ways to Present
Try serving the pasta in individual ramekins sprinkled with toasted breadcrumbs and broiled just until golden for a delightful crunch. Alternatively, plate it alongside grilled polenta slices or stuffed bell peppers for a colorful, impressive dinner spread.
Make Ahead and Storage
Storing Leftovers
Leftovers can be kept in an airtight container in the refrigerator for up to 3 days. The flavors develop even more, making for a tasty second-day meal. Keep in mind the pasta may soak up the sauce a little, so a splash of broth or cream before reheating can refresh its texture.
Freezing
This One-Pot Sausage Pasta Recipe freezes well. Cool the pasta completely before transferring it to freezer-safe containers. It can be frozen for up to 2 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
Reheat leftovers gently on the stovetop over low heat or in the microwave. Adding a splash of chicken broth or cream will revive the sauce’s creaminess and help prevent the pasta from drying out. Stir occasionally to ensure even warming.
FAQs
Can I use a different type of pasta for this One-Pot Sausage Pasta Recipe?
Absolutely! While rigatoni is recommended for its sturdy texture, other pasta shapes like penne, ziti, or farfalle will work nicely as well. Just watch the cooking time as it may vary slightly.
Is it okay to substitute the heavy cream?
You can substitute heavy cream with half-and-half or whole milk for a lighter version, but expect a less rich, slightly thinner sauce. For a dairy-free option, coconut cream is a possible alternative that adds a unique flavor twist.
What can I use if I don’t have Italian sausage?
If you don’t have Italian sausage, ground pork, turkey, or chicken seasoned with Italian herbs and spices can be a good substitute. Just adjust seasoning to taste to keep that signature flavor.
Can I make this recipe vegetarian?
Yes! Replace the sausage with plant-based sausage or hearty vegetables like mushrooms and zucchini for a delicious vegetarian version. Use vegetable broth instead of chicken broth for full compatibility.
How spicy is this recipe?
The spice level is mild by default, but the optional crushed red pepper flakes allow you to add a gentle kick. Feel free to increase or reduce the red pepper according to your preferred heat level.

- ¼ teaspoon dried Italian seasoning
- ⅛ to ¼ teaspoon coarse salt

- 1 cup marinara sauce
- 12 ounces uncooked rigatoni pasta (about ¾ of a box)
- ½ cup heavy cream
- ½ cup freshly grated Parmesan cheese
- 6 basil leaves, sliced
Instructions
- Cook Sausage and Onion: Warm the olive oil in a large nonstick pot over medium-high heat. Add the Italian sausage and diced onion, breaking up the sausage into small crumbles using a wooden spoon. Cook for about 5 minutes until the sausage is fully cooked and the onion becomes tender. Stir in the minced garlic and cook for about 20 seconds until fragrant. Add the Italian seasoning, salt, black pepper, and crushed red pepper flakes. Stir well to combine. Drain off any excess grease from the pot.
- Add Tomato Paste: Stir in the tomato paste thoroughly to coat the sausage and onion, infusing the mixture with rich tomato flavor.
- Simmer Pasta: Pour in the low-sodium chicken broth, marinara sauce, and uncooked rigatoni pasta. Mix everything together and bring the liquid to a boil over medium-high heat. Once boiling, stir the mixture, cover the pot with a lid, and reduce the heat to a gentle simmer. Let it cook for about 14 minutes, stirring occasionally towards the end to prevent the pasta from sticking. The pasta should absorb most of the liquid and be cooked al dente.
- Add Cream and Cheese: Pour in the heavy cream and warm the mixture through for 1 to 2 minutes. Then, stir in the freshly grated Parmesan cheese and sliced basil leaves until fully combined, creating a creamy, flavorful sauce.
- Serve: Remove the pot from heat. Serve the pasta in bowls and offer additional grated Parmesan cheese at the table for extra flavor.
Notes
- Remove excess grease from the sausage after cooking to avoid a greasy pasta sauce.
- Stir the pasta occasionally during simmering to prevent it from sticking to the pot.
- For a spicier dish, increase the amount of crushed red pepper flakes.
- Use low-sodium chicken broth to control salt levels in the dish.
- Freshly grated Parmesan cheese melts better than pre-grated varieties, enhancing the texture and flavor.
