Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 12 oz tagliatelle pasta and cook for 7-8 minutes until al dente, then drain and reserve 1/2 cup pasta water.
  2. Step 2: While pasta cooks, heat 3 tbsp extra virgin olive oil in a large skillet over medium heat. Add 1 medium finely chopped yellow onion and sauté for 4 minutes until translucent.
  3. Step 3: Add 4 minced garlic cloves and 10 oz sliced cremini mushrooms to the skillet. Cook for 6-7 minutes until mushrooms release moisture and begin to brown.
  4. Step 4: Stir in 1 tsp dried thyme and 2 tbsp tomato paste, cooking 1 minute until fragrant. Pour in 1/2 cup vegetable broth, 1 tsp salt, and 1/2 tsp freshly ground black pepper. Simmer for 5 minutes until sauce thickens.
  5. Step 5: Add the drained pasta to the skillet along with 1/2 cup reserved pasta water. Toss gently to coat the noodles with the ragu.
  6. Step 6: Remove from heat and stir in 1/2 cup grated Parmesan cheese and 2 tbsp torn fresh basil leaves. Serve immediately.
