How to Make One Pot Spicy Italian Sausage Rigatoni Recipe
Step 1: Cook the Rigatoni Pasta
Start by bringing a large pot of salted water to a boil. Adding a generous dash of salt is key—it seasons the pasta from within. Cook the rigatoni until al dente following the package instructions. Once ready, drain the pasta and set it aside. This step ensures your pasta has the perfect bite and is ready to soak up all that spicy goodness later on.
Step 2: Sauté Onions to Sweet Perfection
In that same pot, heat the olive oil over medium heat. Toss in your finely chopped onions and cook until they become tender and translucent, roughly 3-4 minutes. This step builds the savory foundation for your sauce, with the onions melting into the oil and releasing their natural sweetness.
Step 3: Add Garlic for Aromatic Depth
Next, add the minced garlic, sautéing just until fragrant—about 30 seconds. Garlic cooks quickly and infuses the entire dish with a warm, inviting aroma that is simply irresistible.
Step 4: Brown the Spicy Italian Sausage
Time to add the star protein! Toss in the spicy Italian sausage, removing the casings beforehand so it breaks apart easily. Use a wooden spoon to crumble the meat as it cooks, letting it brown evenly for about 5-7 minutes. This caramelization step adds incredible depth and fiery flavor to the dish.
Step 5: Toast the Red Pepper Flakes
Sprinkle in the red pepper flakes to the sausage mixture, toasting them for a full minute. This helps release their spicy oils and intensifies the heat without overpowering the other flavors. You can always adjust the amount to suit your taste buds.
Step 6: Add Tomatoes and Broth, Then Simmer
Pour in the crushed tomatoes and chicken broth, stirring to combine everything thoroughly. Bring the pot to a gentle simmer, letting the flavors meld and the sauce begin to thicken. This creates a deliciously tangy and savory base for your creamy pasta.
Step 7: Stir in Heavy Cream and Season
Reduce the heat to low and stir in the heavy cream, which brings a velvety richness to the sauce. Season with salt and pepper to your liking, enhancing all the layers of flavor. The cream softens the tomato’s acidity and tempers the sausage’s spice wonderfully.
Step 8: Combine Pasta with Sauce
Return the cooked rigatoni to the pot, tossing gently to ensure every piece is coated in that luscious, spicy sauce. This step makes it a true one pot meal — everything coming together harmoniously with minimal fuss.
Step 9: Fold in Parmesan Cheese
Sprinkle in the grated Parmesan and stir until fully melted and incorporated. The cheese thickens the sauce and adds a salty, nutty finish that keeps you coming back for more.
Step 10: Serve and Enjoy!
Ladle the spicy rigatoni into bowls, garnish with fresh basil leaves, and savor the comforting warmth of this incredible meal you’ve whipped up without breaking a sweat.

Garnishes
Fresh basil leaves are the classic choice, adding a burst of freshness and color that beautifully contrasts the rich sauce. For an extra touch, a sprinkle of additional grated Parmesan or a drizzle of good-quality olive oil brings the dish to life.
Side Dishes
This hearty meal pairs wonderfully with something crisp and simple. Consider a bright green salad with a tangy vinaigrette or garlic bread to soak up the extra sauce. Roasted vegetables like asparagus or broccoli make fresh, healthy companions that balance the richness perfectly.
Creative Ways to Present
For a fun twist, try serving this One Pot Spicy Italian Sausage Rigatoni Recipe in mini cast iron skillets or individual ramekins—perfect for dinner parties or family-style meals.

Make Ahead and Storage
Storing Leftovers
This dish stores beautifully in an airtight container in the refrigerator for up to 3 days. Make sure to cool it completely before sealing to maintain freshness and avoid sogginess.
Freezing
You can freeze leftovers in portion-sized freezer-safe containers for up to 2 months. Keep in mind the texture of pasta can change slightly after thawing, but the sauce will stay rich and flavorful.
Reheating
Reheat gently on the stovetop over low heat, stirring often and adding a splash of water or broth if the sauce has thickened too much. Alternatively, use the microwave in short bursts, stirring between intervals to heat evenly without drying out the pasta.
FAQs
Can I use mild sausage instead of spicy Italian sausage?
Absolutely! Using mild sausage will reduce the heat but still provide wonderful flavor. If you want to keep some spice, just increase the red pepper flakes slightly or add a pinch of cayenne pepper.
Is it necessary to cook the pasta separately?
For this recipe, yes—to achieve perfectly al dente rigatoni, cooking it separately and then combining with the sauce ensures the best texture and timing with the sausage and sauce.
Can I make this recipe vegetarian?
Yes! Replace the sausage with hearty plant-based sausage or sautéed mushrooms and add extra seasoning to mimic the smoky spice. The creamy tomato sauce remains just as delicious.
What type of Parmesan cheese is best?
Freshly grated Parmesan from a block is ideal for melting smoothly into the sauce. Pre-grated versions work too, but the flavor and texture won’t be quite as rich.
Can I prepare this recipe ahead and reheat for guests?
Definitely. This One Pot Spicy Italian Sausage Rigatoni Recipe holds up well when reheated, making it a great make-ahead option for busy weeknights or casual entertaining.
