Description
Savory, melty, and packed with deep caramelized flavor—this French onion twist on baked chicken is pure comfort. Swimming in golden oniony goodness and topped with bubbling Swiss or Gruyère, it’s made to be served over creamy mash or crusty bread to catch every drop of that rich, beefy sauce.
Ingredients
2–3 boneless, skinless chicken breasts
2 large yellow onions, thinly sliced
1 tbsp butter + 1 tbsp olive oil
1/2 cup beef broth
1 tsp balsamic vinegar (optional, for depth)
1 tsp thyme (fresh or dried)
1 cup shredded Swiss or Gruyère cheese
Salt & pepper to taste
To Serve
Mashed potatoes or toasted sourdough
Instructions
Preheat oven to 375°F (190°C).
In a skillet, melt butter and olive oil. Add onions, thyme, and a pinch of salt. Cook over medium-low, stirring often, until golden and caramelized (about 20–25 min).
Deglaze with beef broth and balsamic vinegar. Simmer 2–3 minutes.
Place chicken breasts in a baking dish. Season with salt and pepper. Pour onion mixture over top.
Cover with foil and bake for 25–30 minutes, until chicken is nearly done.
Uncover, sprinkle cheese on top, and broil for 3–5 minutes until bubbly and golden.
Serve hot over mashed potatoes or toasted sourdough.
