Ingredients
- 12 oz uncooked penne pasta
- 8 oz, sliced button mushrooms
- 5 oz (about 5 cups) fresh baby spinach
- 3, minced garlic cloves
- 2 tbsp olive oil
- 4 cups vegetable broth
- 1 cup half-and-half
- 3/4 cup grated Parmesan cheese
- 1 tsp, divided salt
- 1/2 tsp, divided black pepper
- 1/4 tsp, optional red pepper flakes
- 2 tbsp chopped, for garnish fresh parsley
Instructions
- Step 1: In a large deep skillet or Dutch oven, heat 2 tbsp olive oil over medium-high heat. Add 8 oz sliced button mushrooms and sauté for 5-6 minutes until browned and their moisture evaporates.
- Step 2: Add 3 minced garlic cloves and sauté for 30 seconds until fragrant. Pour in 4 cups vegetable broth and 12 oz uncooked penne pasta. Stir and bring to a boil.
- Step 3: Reduce heat to medium-low and simmer uncovered for 12-14 minutes, stirring occasionally, until the pasta is tender and most of the broth is absorbed.
- Step 4: Stir in 1 cup half-and-half, 5 oz fresh baby spinach, 3/4 cup grated Parmesan cheese, 1/2 tsp salt, 1/4 tsp black pepper, and 1/4 tsp red pepper flakes if using. Cook for 2-3 minutes until spinach wilts and sauce thickens slightly.
- Step 5: Taste and adjust seasoning with remaining 1/2 tsp salt and 1/4 tsp black pepper. Garnish with 2 tbsp chopped fresh parsley and serve hot.
