This dish comes together smoothly once ingredients are prepped. The key is building flavor step by step so every layer tastes rich and balanced. Take your time browning and simmering for best results.
Heat olive oil in a large sauté pan over medium-high heat. Add sausage and break it into small pieces as it cooks. Let it brown well, creating flavorful bits that deepen the sauce.
Reduce heat and add butter, onions, and fennel to the pan. Cook until soft and lightly caramelized, about 6–8 minutes. This softens the fennel and blends sweetness with savory sausage.
Stir in garlic, tomato paste, and Calabrian chili peppers until fragrant. Add wine and let it reduce slightly, then stir in tomato purée, cream, oregano, and sausage. Simmer gently until smooth and cohesive.
Boil pappardelle in salted water until al dente. Reserve some pasta water, drain, and toss pasta directly into the sauce. Add parmesan and splash of pasta water to coat noodles perfectly.
