  • 4 skinless boneless chicken breasts
  • 2 large sweet onions cut in 1/8's
  • 1 pound white button mushrooms stemmed and halved
  • 1/2 pound baby red new potatoes halved
  • 1/2 tablespoon minced dried onion
  • 1/2 tablespoon granulated garlic
  • 1/2 tablespoon dried rosemary
  • 1 bottle 18 ounces barbecue sauce - your favorite
  • Kosher salt and ground black pepper


  1. Preheat the oven to 350F.
  2. Lightly oil or spray a 9 x 13 baking dish. Lay the chicken in a single layer, then put in the onion chunks and the mushrooms. Make room for the red potatoes. Try to keep everything in a single layer - you may need to squish the chicken pieces and rearrange some of the vegetables.
  3. Season the chicken and vegetables with the kosher salt and black pepper.
  4. Combine the dried onion, garlic and rosemary, then sprinkle the mixture over the chicken and vegetables.
  5. Pour the barbecue sauce evenly over the chicken and vegetables. Cover the baking dish with aluminum foil and bake for 1 hour.
  6. The chicken should be cooked through and register 180F and the vegetables should be tender and cooked through.
