Making Garlic Parmesan Kale Pasta is easy and straightforward with these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain and reserve about ½ cup of the pasta water.
2. Sauté the Garlic: In a large skillet, heat the olive oil over medium heat. Add the minced garlic and red pepper flakes if using. Sauté for about 1-2 minutes until fragrant, being careful not to burn the garlic.
3. Add Kale: Toss in the chopped kale into the skillet. Cook for about 4-5 minutes until the kale is wilted and tender, stirring occasionally.
4. Combine with Pasta: Add the drained pasta to the skillet with the kale. Pour in the reserved pasta water, a little at a time, until you reach your desired sauce consistency.
5. Season and Add Cheese: Stir in the grated Parmesan cheese, lemon juice, salt, and pepper. Mix until the pasta is well coated and all ingredients are combined.
6. Garnish: Remove from heat, garnish with chopped parsley, and serve hot.
