Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large deep skillet over medium heat. Add 3 cloves minced garlic and sauté for 1 minute until fragrant but not browned.
  2. Step 2: Add 12 oz penne pasta to the skillet along with 4 cups vegetable broth, 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes. Stir well and bring to a boil over high heat.
  3. Step 3: Reduce heat to medium-low and simmer uncovered for 10 minutes, stirring occasionally to prevent sticking.
  4. Step 4: After 10 minutes, stir in 4 cups fresh spinach and 1 cup frozen peas. Continue cooking for 3-4 minutes until spinach is wilted and peas are tender.
  5. Step 5: Stir in 3/4 cup grated Parmesan cheese and 1/4 cup heavy cream, cooking for another 2 minutes until the cheese melts and the sauce thickens slightly, coating the pasta evenly.
