Preparing Creamy Lemon Chicken Pasta is straightforward when you follow these simple steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.

2. Prepare the Chicken: While the pasta is cooking, season the chicken breasts with salt and pepper.

3. Cook the Chicken: In a large skillet, heat olive oil over medium heat. Add the seasoned chicken and cook for about 5-7 minutes per side, or until the chicken is golden brown and cooked through. Remove the chicken from the skillet and let it rest for a few minutes before slicing.

4. Sauté Garlic: Using the same skillet, add minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.

5. Add Cream and Lemon: Pour in the heavy cream, lemon zest, and lemon juice into the skillet. Stir well and let it simmer for about 2-3 minutes.

6. Incorporate Cheese: Gradually stir in the grated Parmesan cheese until melted and smooth, creating a creamy sauce. If the sauce is too thick, add a splash of the reserved pasta water to thin it out.

7. Combine Chicken and Pasta: Add the cooked pasta and sliced chicken into the skillet, tossing to coat in the creamy lemon sauce. If using spinach, add it now, and stir until wilted.

8. Season to Taste: Adjust seasoning with salt and pepper as needed.

9. Serve Hot: Plate the pasta, ensuring an even distribution of chicken and sauce, and garnish with fresh parsley.
