Prepare the Chicken: Season the chicken breasts with garlic powder, onion powder, salt, and pepper.
Cook the Chicken: Heat olive oil in a large skillet over medium-high heat. Cook the chicken breasts for 5–7 minutes per side, until golden brown and cooked through, with an internal temperature of 165°F (74°C). Remove the chicken from the skillet and set aside.
Make the Creamy Sauce: In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1–2 minutes until fragrant.
Add Cream and Broth: Pour in the heavy cream and chicken broth. Stir to combine, scraping up any browned bits from the bottom of the pan. Let the sauce simmer for 4–5 minutes, until it thickens slightly.
Finish the Sauce: Stir in the Parmesan cheese and let it melt into the sauce. Adjust the seasoning with salt and pepper if needed.
Combine Chicken and Sauce: Return the cooked chicken to the skillet, spoon the sauce over the chicken, and simmer for another 2–3 minutes, allowing the chicken to soak up the flavors.
Serve: Garnish with fresh parsley and serve immediately over rice, pasta, or vegetables of your choice.
