Season the chicken breasts with salt and black pepper on both sides.
In a large skillet, heat the olive oil over medium-high heat. Add the chicken breasts and cook for about 5-7 minutes on each side, or until cooked through and golden brown. Remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic, thyme, oregano, and red pepper flakes (if using). Sauté for about 1 minute until fragrant.
Pour in the chicken broth and heavy cream, stirring to combine. Bring the mixture to a simmer.
Add the ramen noodles to the skillet and cook according to package instructions, usually about 3-4 minutes, until tender.
Stir in the cherry tomatoes and baby spinach, cooking until the spinach wilts, about 2 minutes.
Slice the cooked chicken and return it to the skillet, mixing everything together. Sprinkle with grated Parmesan cheese before serving.
Garnish with fresh basil leaves and serve immediately.
