Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large deep skillet over medium heat. Add 4 minced garlic cloves and sauté for 1 minute until fragrant, then add 8 oz sliced white mushrooms and cook for 5 minutes until tender and golden.
  2. Step 2: Pour in 4 cups vegetable broth and bring to a boil. Add 12 oz penne pasta, stir, and reduce heat to a simmer. Cook uncovered for 12-14 minutes, stirring occasionally, until pasta is al dente and most liquid is absorbed.
  3. Step 3: Stir in 4 cups baby spinach, 1 cup grated Parmesan cheese, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes if using. Cook for 2 more minutes until spinach wilts and cheese melts, creating a creamy sauce that coats the pasta.
  4. Step 4: Remove from heat and let rest for 2 minutes before serving.
