Ingredients
  

Chicken
  • 4 boneless skinless chicken breasts Use same thickness for even baking.
  • salt
  • pepper
  • garlic powder To taste for seasoning and sauce.
  • smoked paprika To taste for seasoning.
Sour cream topping
  • 1 cup sour cream
  • 0.5 cup mayonnaise
  • 1 packet (1 oz) ranch seasoning mix
  • 1 tsp garlic powder For the sauce.
Cheese and bacon
  • 1.5 cup shredded cheddar cheese Divide for topping.
  • 0.5 cup Parmesan cheese, grated
  • 6 bacon Cook crispy and crumble.
  • fresh chives For garnish.

Equipment

  • 1 sheet pan

Method
 

Prep and preheat
  1. Preheat oven to 375°F and grease a 9x13 baking dish. Make sure the dish is evenly coated so the topping releases cleanly.
  2. Season the chicken breasts with salt, pepper, garlic powder, and smoked paprika to taste, then place them in the prepared dish. Arrange them in a single layer so the topping bakes evenly across the surface.
Make the sour cream mixture
  1. Whisk together sour cream, mayonnaise, ranch seasoning mix, and 1 teaspoon garlic powder until smooth. The mixture should look glossy and fully combined.
  2. Spread the sour cream mixture generously over each chicken breast. Cover to the edges so the top turns golden-bubbly during baking.
Cheese, bacon, and bake
  1. Top with shredded cheddar cheese and grated Parmesan, then scatter crumbled bacon over the surface. Press the cheese lightly so it stays put as the sauce simmers in the oven.
  2. Bake at 375°F for 28-32 minutes, until the topping is golden and bubbly and the internal temperature reaches 165°F. Look for caramelized browned spots across the top while the chicken edges stay juicy.
  3. Garnish with fresh chives immediately after baking. The green garnish adds color right before serving.

Notes

For cleaner slicing, rest the baked chicken for 5 minutes before serving so the cheesy topping thickens. Store leftovers in the refrigerator up to 3-4 days in an airtight container. Freezing isn’t recommended because the sour cream-cheese topping can separate after thawing. Dietary swap: use light sour cream or reduced-fat cheddar to cut calories while keeping the tangy baked topping.
