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 onion, finely diced, and cook for 5 minutes until softened and translucent.
  3. Step 3: Add 3 garlic cloves, minced, and 8 oz cremini mushrooms, sliced, to the skillet. Cook for 7 minutes until mushrooms release moisture and turn golden brown, stirring occasionally.
  4. Step 4: Pour in 1 cup vegetable broth and 1/2 cup heavy cream, stirring to combine. Bring to a gentle simmer and cook for 3 minutes until slightly thickened.
  5. Step 5: Add the drained spaghetti to the skillet along with 2 cups fresh spinach and 1/4 tsp red pepper flakes. Toss until spinach wilts completely, about 2 minutes.
  6. Step 6: Stir in 1/4 cup grated Parmesan cheese and 1/2 cup reserved pasta water. Cook for 1 minute, stirring until sauce coats the pasta evenly.
  7. Step 7: Season with salt and black pepper to taste and serve immediately.
