Stephanie, the Crockpot Lady, keeps coming out with great recipes, even though her year of Crockpotting is officially over! Here is another one:
1 1/2 lbs boneless chicken, cut in 2-inch pieces
1/2 C gluten free flour
olive oil, for browning the chicken
1 T kosher salt
6 oz (1/2 can) frozen orange juice concentrate, thawed (little or no pulp is best)
3 T brown sugar
1 tsp balsamic vinegar
3 T ketchup
Stephanie says to use a 4 quart Crockpot for best results. Coat the chicken pieces with the flour, and shake off any excess. Heat olive oil in a large skillet and brown the chicken on all sides. Sear it just enough for the flour to stick.
Place the chicken pieces into the Crockpot. In a small mixing bowl, combine orange juice concentrate, brown sugar, balsamic vinegar, salt, and ketchup. Taste; add more sugar if you want it sweeter. Pour sauce mixture evenly over the chicken, and toss to coat.
Cover and cook on low for 6 hours, or on high for 3 to 4. Serve over white or brown rice.
