Chop the Vegetables: Chop 2 pounds mushrooms in batches with a knife or food processor and set aside. Chop 1 large onion, 2 medium carrots, 1 rib celery, and 3 cloves garlic the same way.
Start the Sauce: Heat 2 tablespoons extra virgin olive oil in a large pan. Add chopped onion, carrot, celery, garlic, 1 teaspoon dried oregano, and ½ cup tomato paste. Cook for 5 minutes, stirring until soft and fragrant. Add a splash of water if it sticks.
Cook the Mushrooms: Add chopped mushrooms, ¾ teaspoons salt, and pepper. Cook on medium-high for about 20 minutes, stirring sometimes, until all liquid is gone. Stir in 1 tablespoon balsamic vinegar, taste, and adjust.
Boil the Pasta: Cook 12 ounces fettuccine in salted boiling water until al dente. Save 1 cup of the cooking water, then drain.
Mix and Serve: Add pasta to the mushroom sauce with a splash of cooking water. Toss well, then top with 10 leaves fresh basil, a drizzle of olive oil, and parmesan.

Tips
Make it ahead: The ragu thickens and tastes even better the next day—perfect for meal prep.
Use a food processor: Chop veggies and mushrooms in batches to save time. Pulse gently to keep texture.
Use a wide skillet: More surface area means mushrooms release water faster, giving you a rich sauce instead of steaming.
Don’t rush the soffritto: Slowly soften onion, carrot, and celery.
Boost umami: A splash of balsamic adds balance. Soy sauce works too, just go lighter since it’s saltier.
Loosen with broth if needed: If the ragu feels too thick, stir in a little vegetable broth or water.
Reserve pasta water: The starchy water helps the sauce cling to pasta for that silky restaurant finish.
Garnish generously: Basil, parmesan, or nutritional yeast add freshness and a burst of flavor.
StorageStore leftovers in an airtight container in the fridge for up to 3 days, or freeze the mushroom ragu for up to 3 months.
