Ingredients
- 12 ounces, penne pasta
- 8 ounces, sliced mushrooms
- 1 medium, finely chopped onion
- 3 cloves, minced garlic
- 1/2 cup heavy cream
- 3 cups fresh spinach
- 1/2 cup, grated Parmesan cheese
- 2 tablespoons olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Instructions
- Step 1: Bring a large pot of salted water to a rolling boil. Add 12 ounces penne and cook for 8-10 minutes until al dente, reserving 1/2 cup pasta water before draining.
- Step 2: While pasta cooks, heat 2 tablespoons olive oil in a large skillet over medium heat. Add 8 ounces sliced mushrooms and 1 medium chopped onion; cook for 5 minutes until mushrooms release liquid and onions soften.
- Step 3: Stir in 3 minced garlic cloves and cook for 1 minute until fragrant, then add drained pasta, 1/2 cup heavy cream, 3 cups fresh spinach, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
