French Onion Chicken

French Onion Chicken

Ingredients:
1 large yellow onion, thinly sliced in half or quarter moons
1 tablespoon butter
salt
pepper
1/4 cup chicken broth or stock (I make my own crock-pot stock)
1 chicken breast, cooked and roughly chopped
1/4 cup Gruyere cheese, shredded

Directions:
Preheat oven to 350F

Heat butter over medium heat in cast iron skillet. Add onion, salt and pepper. Stir to combine. Cook over medium heat for 10 minutes, stirring occasionally. Decrease heat to medium-low and cook for another 20 minutes, stirring occasionally. Decrease heat once more, this time to low, and cook an additional 10 minutes. Add 1/4 cup chicken broth, being sure to scrape up any tasty bits the onions stuck to the pan. Add chicken and stir to combine. Top with Gruyere cheese and bake for 5 - 10 minutes or until cheese is melted and chicken is warmed through.
