Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a rolling boil. Add 8 oz spaghetti and cook for 8-10 minutes until al dente, then drain and reserve 1/2 cup pasta water.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 medium finely chopped onion and 3 minced garlic cloves, sautéing for 3 minutes until softened and fragrant.
  3. Step 3: Add 8 oz sliced cremini mushrooms to the skillet and cook for 5 minutes until they release moisture and brown slightly.
  4. Step 4: Pour in 1/2 cup white wine and simmer for 2 minutes until reduced by half, then stir in 1 cup heavy cream and cook for 2 minutes until thickened.
  5. Step 5: Add the drained spaghetti to the skillet along with 1/2 cup reserved pasta water and 1/4 cup grated Parmesan cheese. Toss vigorously for 1 minute until the cheese melts and the sauce coats every strand.
