Creating Creamy Tuscan Chicken Pasta is straightforward if you follow these simple steps:

1. Cook Pasta: Boil salted water in a large pot and add the fettuccine. Cook according to package instructions until al dente. Drain and set aside.
2. Prepare Chicken: While pasta cooks, season the chicken breasts with salt, pepper, and Italian seasoning.
3. Sauté Chicken: In a large skillet, heat olive oil over medium heat. Add the chicken and cook for 6-7 minutes on each side or until fully cooked and golden brown. Remove from the skillet and set aside.
4. Sauté Garlic: In the same skillet, add minced garlic and sauté for about a minute until fragrant.
5. Add Vegetables: Add chopped sun-dried tomatoes and spinach. Cook until the spinach wilts down, about 2-3 minutes.
6. Make the Sauce: Lower the heat and pour in the heavy cream. Stir well to combine. Let it simmer for 2-3 minutes.
7. Add Cheese: Incorporate grated Parmesan cheese and stir until melted and smooth. Add red pepper flakes if using.
8. Combine: Slice the cooked chicken and add it back to the skillet, along with the drained pasta. Toss everything together until the pasta is well coated in sauce.
9. Adjust Seasoning: Taste and season with salt and pepper as needed.
10. Serve: Garnish with fresh basil before serving.
