Sour Cream Onion Chicken (Printable)

Juicy chicken breasts baked in a creamy sour cream and onion sauce for a flavorful dinner.

# What You’ll Need:

→ Chicken

01 - 4 boneless, skinless chicken breasts (about 6 oz each)
02 - 1 teaspoon kosher salt
03 - ½ teaspoon freshly ground black pepper

→ Sour Cream & Onion Sauce

04 - 1 cup sour cream
05 - ½ cup mayonnaise
06 - ½ cup finely chopped green onions (plus extra for garnish)
07 - 1 packet (1 oz) dry onion soup mix
08 - 2 teaspoons garlic powder
09 - 1 teaspoon onion powder
10 - 2 tablespoons milk

→ Topping

11 - ½ cup shredded cheddar cheese
12 - ½ cup crushed gluten-free crackers or potato chips (optional, for crunch)

# How to Prepare:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or a small amount of oil.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with kosher salt and freshly ground black pepper. Arrange seasoned chicken in the prepared baking dish in a single layer.
03 - In a medium bowl, combine sour cream, mayonnaise, chopped green onions, dry onion soup mix, garlic powder, onion powder, and milk. Whisk until completely smooth and well incorporated.
04 - Spread the sour cream and onion mixture evenly over each chicken breast, ensuring complete coverage.
05 - Sprinkle shredded cheddar cheese evenly over the sauced chicken. If desired, add crushed gluten-free crackers or potato chips for extra texture.
06 - Bake uncovered for 25 to 30 minutes, or until chicken reaches an internal temperature of 165°F and the sauce is bubbly around the edges.
07 - Remove from oven and let rest for 5 minutes to allow juices to redistribute. Garnish with additional chopped green onions before serving.

# Expert Advice:

01 -
  • The sauce keeps the chicken remarkably juicy even if you accidentally overcook it slightly
  • Everything comes together in one bowl with ingredients you probably already have
  • My picky eater who claims to hate onions asked for seconds
02 -
  • Thinner chicken breasts will cook faster so check them at 20 minutes to avoid drying out
  • The sauce will look thin going into the oven but thickens beautifully as it bakes
03 -
  • Let the chicken come to room temperature for 20 minutes before cooking for even results
  • Extra green onions sprinkled on top right before serving add a fresh pop
