3 T. butter
2 lb. onions, sliced
2-3 cloves garlic, chopped
1 t. thyme, chopped
2 T. flour
2 c. beef or chicken stock/broth
1 T. olive oil
1 lb. boneless, skinless chicken breasts or thighs
salt and pepper, to taste
1 T. balsamic vinegar
2 T. Dijon mustard
1 c. gruyere cheese, grated
1. Melt butter in a pan over medium heat; add onions; cook until a deep golden brown, about 1 hour, stirring occasionally. Add a bit of water or stock/broth to deglaze the pan, as needed.
2. Add garlic, thyme and flour; cook for 1 minute while stirring. Add half of the stock/broth, deglaze the pan; bring to a boil; reduce heat; simmer for 5 minutes.
3. Meanwhile, heat oil in a skillet over medium-high heat; season chicken with salt and pepper; add chicken; brown on both sides, about 2-4 minutes per side; set aside.
4. Preheat oven to 350 degrees.
5. Add remaining cup of stock/broth to the skillet to deglaze it; stir in balsamic vinegar and mustard; bring to a boil; reduce heat; simmer to reduce by half, about 5 minutes.
6. Place onions in an oven safe pan; top with the chicken and stock/broth from the chicken; cover with a lid or foil; bake for 20 minutes. Sprinkle on the gruyere cheese; broil until cheese has melted, about 2-4 minutes.**
