Season chicken breasts with garlic powder, onion powder, chili powder, paprika, salt, and pepper.
Melt butter in a large skillet over medium-high heat.
Add chicken breasts to the skillet and cook for 5-7 minutes per side, until golden brown and cooked through.
Remove chicken from skillet and set aside.
Pour in heavy cream and chicken broth, scraping up any browned bits from the bottom of the skillet.
Bring to a simmer and cook for 5 minutes, or until sauce has slightly thickened.
Stir in Parmesan cheese.
Return chicken to the skillet and coat with sauce. Garnish with fresh parsley and serve.
