04 - 1 cup sour cream

→ Topping

11 - ½ cup shredded cheddar cheese

02 - Pat chicken breasts dry and season both sides with salt and pepper. Arrange in the prepared baking dish.
03 - In a medium bowl, combine sour cream, mayonnaise, green onions, onion soup mix, garlic powder, onion powder, and milk. Mix until smooth.
04 - Spread the sour cream and onion mixture evenly over the chicken breasts.
05 - Sprinkle cheddar cheese and, if using, crushed crackers or chips on top.

07 - Let rest for 5 minutes. Garnish with extra green onions before serving.

# Expert Advice:

01 -
  • The sauce creates its own rich gravy perfect for spooning over everything on your plate
  • Minimal prep work means you can get this in the oven in under ten minutes
  • The topping gets golden and slightly crunchy while the chicken stays incredibly moist
02 -
  • Using chicken at room temperature helps it cook more evenly, so take it out of the fridge about 20 minutes before starting
  • The sauce will look thin going into the oven but thickens beautifully as it bakes
  • Overbaking causes the sauce to separate, so check for doneness at the 25 minute mark
03 -
  • Pound the chicken breasts to an even thickness so they all finish cooking at the same time
  • For extra flavor, add a pinch of smoked paprika to the sauce mixture
  • Use freshly grated cheese instead of pre-shredded for the smoothest melting texture
