Step 1

In a large pot, bring 4 quarts water to a boil. Add the pasta and 1 tablespoon salt, then cook, stirring occasionally, until al dente. Reserve 1 cup of the cooking water, then drain and return the pasta to the pot.

Step 2

Meanwhile, in a 12-inch skillet, combine the oil, pancetta, onion and garlic. Cook over medium, stirring occasionally, until the pancetta is lightly browned and the onion is translucent, 8 to 10 minutes. Add the wine and cook, stirring, until almost evaporated, 1 to 2 minutes. Add the mushrooms and cook over medium-high, stirring occasionally, until the moisture they release evaporates, 4 to 5 minutes. Stir in the tomato puree and ½ teaspoon each salt and pepper. Bring to a simmer, then reduce to medium-low and cook, stirring occasionally, until lightly thickened, 3 to 4 minutes.

Step 3

Add the mushroom mixture to the pasta in the pot, along with the cream, ½ cup of the reserved pasta water and the cheese. Cook over medium, stirring, until the sauce clings to the pasta, 3 to 4 minutes; add more pasta water as needed so the sauce lightly coats the noodles. Taste and season with salt and pepper. Serve sprinkled with additional cheese.
