1/2 bottle of root beer (about 1 cup)- I used Barq's
1/2 c dark brown sugar,packed
1/2 c of ketchup
1 tbsp BBQ sauce
2 tbsp pepper jelly or other jam/jelly
1 tsp spicy mustard (I used Dijon)
4 boneless chicken breasts, cut into halves
Combine all ingredients in a sauce pan and bring to a boil. Reduce heat and simmer until reduced and thickened. Hold over a very low heat until needed. Separate the sauce into two bowls (one for brushing on raw chicken and one for serving with your chicken on the side)
Preheat oven to 350º and line cookie sheet with foil or spray with non-stick spray.
Season your chicken with salt, pepper, garlic and onion powder on both sides. Place on baking sheet and brush them with the root beer sauce. Bake about 10 minutes then turn over and brush with more root beer sauce and continue baking in oven until they are done how you like them and thoroughly cooked through - about 15 minutes more. You can take the heat outside and grill it too.
