Description

French Onion Chicken Bake

A comforting, flavor-packed dinner that’s elegant enough for guests but simple enough for a weeknight.


Ingredients

Scale
  • 4 boneless, skinless chicken breasts

  • 2 tbsp olive oil

  • 2 large yellow onions, thinly sliced

  • 1 tbsp balsamic vinegar or dry white wine (optional)

  • 1 cup beef or chicken broth

  • 1 tsp garlic, minced

  • 1 tsp fresh thyme or ½ tsp dried

  • 1½ cups shredded mozzarella or Swiss cheese (or a blend)

  • Salt & pepper, to taste

  • Fresh parsley, chopped (optional, for garnish)


Instructions

  1. Preheat & Prep:

    • Oven: 375°F (190°C).

    • Lightly grease a 9×13-inch baking dish.

    • Pat chicken dry, season both sides with salt and pepper.

  2. Caramelize the Onions:

    • Heat olive oil in a large skillet over medium heat.

    • Add sliced onions, stir occasionally for 15–20 minutes until soft and golden.

  3. Deglaze & Make the Sauce:

    • Stir in minced garlic for 60 seconds.

    • Add balsamic vinegar or wine to deglaze the pan, scraping up browned bits.

    • Pour in broth and sprinkle in thyme. Simmer 2–3 minutes to thicken slightly. Taste and season with salt as needed.

  4. Assemble the Bake:

    • Place chicken breasts in prepared dish.

    • Pour onion and broth mixture evenly over the chicken.

    • Sprinkle shredded cheese over the top.

  5. Bake:

    • Bake 25–30 minutes until chicken reaches 165°F internally and cheese is melted and golden.

  6. Garnish & Serve:

    • Let rest 5 minutes.

    • Scatter chopped parsley over the top.

Notes

  • Over garlic mashed potatoes to soak up the oniony sauce.

  • With a fresh green salad to balance richness.

  • Accompanied by crusty bread or toasted sourdough.

  • Low-carb option: serve over cauliflower mash or roasted veggies.
