Ingredients
- 12 oz uncooked fettuccine pasta
- 4 cups water
- 4 cloves garlic cloves, minced
- 2 tbsp olive oil
- 4 cups fresh baby spinach
- 1 cup grated Parmesan cheese
- 1/2 cup heavy cream
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 tsp red pepper flakes (optional)
Instructions
- Step 1: In a large deep skillet or pot, combine 12 oz uncooked fettuccine pasta, 4 cups water, 2 tbsp olive oil, 4 minced garlic cloves, and 1 tsp salt. Bring to a boil over medium-high heat and cook for 10 minutes, stirring occasionally to prevent sticking.
- Step 2: When the pasta is almost tender, stir in 4 cups fresh baby spinach and cook for 2 more minutes until the spinach wilts and the pasta is al dente.
- Step 3: Lower the heat to medium and add 1/2 cup heavy cream, 1 cup grated Parmesan cheese, 1/2 tsp black pepper, and 1/4 tsp red pepper flakes if using. Stir continuously for 2-3 minutes until the sauce thickens and coats the pasta evenly.
