Preheat the Oven – Set your oven to 400°F (200°C) and grease a baking sheet.
Prepare the Chicken – Pound the chicken breasts to an even thickness for uniform cooking. Season with salt and pepper.
Make the Ranch Mixture – In a bowl, mix sour cream and ranch seasoning until well combined.
Marinate – Coat each chicken breast in the sour cream mixture. Cover and marinate for at least 30 minutes (optional but enhances flavor).
Prepare the Breading – In a separate bowl, mix panko breadcrumbs, cheddar cheese, Parmesan cheese, garlic powder, and paprika.
Coat the Chicken – Dredge each marinated chicken breast in the breadcrumb mixture, pressing down to ensure an even coating.
Bake – Place the coated chicken on the greased baking sheet and bake for 25-30 minutes, or until the internal temperature reaches 165°F (75°C).
Rest & Serve – Let the chicken rest for 5 minutes before serving. Garnish with fresh parsley and enjoy!
