Bistro French Onion Chicken Recipe

In a large nonstick skillet, cook and stir onion in 1 teaspoon oil over medium-low heat for 10 minutes. Stir in brown sugar and vinegar; cook 5-10 minutes longer or until tender and golden brown. Remove and keep warm. In the same skillet, brown chicken in remaining oil on both sides. Add broth, stirring to loosen browned bits from pan.

Cover and bake at 350° for 15 minutes. Uncover, bake 3-5 minutes longer or until a meat thermometer reads 170°. Yield: 4 servings.
