Instructions
Start by bringing a large pot of salted water to a vigorous boil. Add the fettuccine or spaghetti and cook according to the package instructions until al dente. Once cooked, reserve about 1/2 cup of the pasta water, then drain the pasta in a colander and set it aside.
In a large skillet over medium heat, melt 2 tablespoons of the unsalted butter. Once the butter is sizzling, add the diced chicken breast. Season generously with salt and pepper and cook, stirring occasionally, until the chicken is golden brown and fully cooked through, approximately 6 to 8 minutes. When done, transfer the chicken to a plate and set aside.
In the same skillet, add the remaining 2 tablespoons of butter. Allow it to melt and become bubbly. Then, add the minced garlic and sauté for about 1 minute, stirring constantly, until fragrant and just starting to turn golden.
Next, add the halved cherry tomatoes to the skillet. Sauté for another 2 to 3 minutes until the tomatoes begin to burst and soften, releasing their juices.
Incorporate the spinach leaves along with the optional red pepper flakes, sautéing until the spinach is wilted and well mixed.
Return the cooked chicken to the skillet, then gently combine all the ingredients. Add the drained pasta along with a splash of the reserved pasta water to help marry the flavors together. Use tongs to toss the mixture carefully, ensuring the pasta gets well coated.
Stir in the grated Parmesan cheese, mixing until fully melted and combined. Taste and season with additional salt and freshly ground black pepper as needed. If you find the pasta mixture appears dry, gradually add more of the reserved pasta water until you achieve a creamy consistency.
Serve immediately, plated in warm bowls and garnished with fresh basil leaves. If desired, sprinkle additional grated Parmesan cheese on top for an extra layer of flavor.
