Creating Creamy Chicken Pesto Pasta with Spinach is simple and enjoyable. Follow these steps for a successful dish:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.
2. Prepare the Chicken: While the pasta cooks, season the chicken breasts with salt and pepper. Heat olive oil in a large skillet over medium heat.
3. Cook the Chicken: Add the chicken to the skillet and cook for about 5-7 minutes on each side until golden brown and cooked through. Remove from the skillet and let it rest for a few minutes before slicing it into strips.
4. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 30 seconds until fragrant.
5. Make the Sauce: Pour in the heavy cream and stir in the basil pesto. Allow it to simmer for about 2-3 minutes, stirring occasionally.
6. Add Spinach: Add the fresh spinach to the sauce and cook until wilted, about 2 minutes.
7. Combine: Add the cooked pasta to the sauce and toss to coat evenly. Add the sliced chicken on top and mix gently.
8. Serve: Remove from heat and serve immediately. Top with grated Parmesan cheese and fresh basil if desired.

By following these straightforward steps, you will create a Creamy Chicken Pesto Pasta with Spinach that is both delicious and satisfying.
