Season the chicken breast with garlic powder, onion powder, salt, and pepper.
Heat the olive oil in a skillet over medium heat and cook the chicken 5-6 minutes per side until fully cooked. Remove and set aside.
In the same pan, reduce the heat to medium-low. Add butter and garlic, cooking for about 30 seconds until fragrant.
Pour in chicken broth and add spinach. Cook until spinach wilts (2–3 minutes).
Stir in parmesan cheese, then return chicken to the pan. Spoon sauce over the top and simmer 2–3 minutes.
