Spinach Lemon Pasta Recipe
Introduction
This Spinach Lemon Pasta is a bright and refreshing dish that comes together quickly for a perfect weeknight dinner. The zing of fresh lemon combined with tender spinach and creamy parmesan makes it both simple and flavorful.

Ingredients
- 8 ounces spaghetti
- 3 tablespoons unsalted butter
- 3 cloves garlic – grated or finely minced
- ¼ teaspoon red pepper flakes
- 1 lemon – zested and then juiced
- 2 cups baby spinach
- ½ cup parmesan cheese – freshly grated
- ½ teaspoon salt – plus more for salting pasta water
- ¼ teaspoon black pepper
Instructions
- Step 1: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions, typically 9 to 10 minutes. Before draining, reserve 1 cup of the pasta water. Do not rinse the pasta.
