Turkey-and-Mushroom Bolognese

Heat 3 tablespoons oil in a pot over medium-high. When it shimmers, add onion, carrots, and mushrooms; season with salt. Cook, stirring occasionally, until vegetables are tender and golden in places, 8 to 10 minutes (if bottom of pot browns too quickly, reduce heat to medium).

Add remaining 1 tablespoon oil, turkey, and pancetta; season with salt and pepper. Cook, breaking turkey into bite-size pieces, until browned in places, about 5 minutes. Stir in garlic and tomato paste; cook until fragrant, about 1 minute more. Add wine and boil, scraping up any browned bits, until mostly evaporated. Add broth and tomato sauce; bring to a boil, then reduce heat to low and simmer, stirring a few times, until thickened and reduced slightly, about 30 minutes.

Stir in milk and continue simmering until again thickened and reduced slightly, 12 to 15 minutes more. Remove from heat. Meanwhile, cook pasta in a large pot of generously salted boiling water according to package instructions.

Drain, reserving 1 cup pasta water. Toss pasta with a few spoonfuls of Bolognese and enough pasta water for sauce to evenly coat pasta. Serve pasta with more Bolognese, topped with cheese, parsley, and a drizzle of oil.
