Sour Cream Onion Chicken (Printable)

Juicy chicken baked in a creamy sour cream and onion sauce with cheddar topping.

# What You 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)

# How to Make It:

01 - Preheat oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or butter.
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 smooth and fully incorporated.
04 - Spread the sour cream and onion mixture evenly over each chicken breast, covering completely.
05 - Sprinkle shredded cheddar cheese evenly over the sauced chicken. If desired, add crushed crackers or potato chips for extra crunch.
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 chicken rest for 5 minutes before serving. Garnish with additional chopped green onions.

# Expert Tips:

01 -
  • The creamy sauce keeps the chicken incredibly moist even after baking
  • It takes practically zero effort but tastes like you spent hours on it
  • Leftovers reheat beautifully for lunch the next day
02 -
  • Dry onion soup mix brands vary wildly in saltiness, so taste your sauce before adding extra salt
  • Overbaking will dry out the chicken, so check the temperature early and often
03 -
  • Crush your crackers or chips right in the bag to save on dishes
  • If the sauce seems too thick, add another tablespoon of milk to loosen it up
