Cook the Chicken: Heat a large skillet over medium heat. Add a drizzle of oil and sauté the chicken pieces for 4-5 minutes until golden and cooked through. Remove and set aside.
Prepare the Sauce: In the same skillet, melt the butter. Add the minced garlic and sauté for 30 seconds until fragrant. Stir in the heavy cream, Parmesan cheese, soy sauce, sesame oil, and chicken broth. Simmer for 2-3 minutes until slightly thickened.
Cook the Noodles: While the sauce simmers, cook the ramen noodles according to the package instructions. Drain and set aside.
Combine and Serve: Add the cooked chicken and noodles to the skillet with the creamy sauce. Toss everything together until well-coated. Garnish with green onions, parsley, and chili flakes (if using). Serve immediately.
