Preheat oven to 400℉ and position a rack in the center of the oven. Spray a large baking dish with non-stick cooking spray.
Trim the chicken of any excess fat, season with salt and pepper, place in baking dish.
Whisk together apricot preserves, Russian dressing, Dijon mustard, soy sauce, onion, garlic, and red pepper flakes. Pour enough over the chicken to almost completely cover it.
Bake chicken for 20-25 minutes, or until internal temperature reaches 165℉ when an instant read thermometer is inserted into the thickest part of the chicken breast. Taste sauce and adjust seasoning. Serve immediately over rice, garnished with sliced green onion.
Notes
French or Catalina dressing can be used in place of the Russian Dressing.The chicken will cook faster in a 9x13” dish than it will in a 2qt baking dish due to the larger surface area.Store leftover chicken in the fridge for up to 3-4 days or freeze in a plastic freezer bag for up to 1 month.Make Ahead: Prep the chicken and sauce in the morning for dinner that night. Cover tightly and refrigerate up to 8 hours. Bake as directed, adding 5-10 minutes to the baking time.Make Ahead and Freeze: Add the chicken breasts to a freezer bag with the apricot sauce and press the air out so the bag is flat. Freeze for up to 3 months and thaw the bag in the fridge for 24 hours before baking.
