Ingredients

Scale

For the Chicken

4 boneless, skinless chicken breasts (pounded to even thickness)
Salt & pepper, to taste
2 tbsp olive oil

For the Onion Gravy

2 large yellow onions, thinly sliced
1 tsp sugar
2 cloves garlic, minced
1 tsp thyme (fresh or dried)
1 tbsp Worcestershire sauce
½ cup beef or chicken broth

For Topping

4 slices Swiss cheese
4 slices provolone cheese
Optional: chopped parsley

Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a 9×13 baking dish.

2. Caramelize the Onions

Heat the olive oil in a large skillet over medium heat.
Add sliced onions and sprinkle with the sugar.
Cook for 15–20 minutes, stirring often, until the onions turn soft, golden, and caramelized.
- Tip: If they start sticking, add a tablespoon of water or broth.

3. Build the Gravy

Add garlic and thyme; cook for 1 minute.
Stir in Worcestershire sauce and broth.
Simmer for 2–3 minutes until slightly thickened.
Season with salt and pepper.

4. Assemble

Place the chicken breasts in your baking dish.
Pour the onion gravy evenly over them.

5. Add the Cheese

Place one slice of Swiss and one slice of provolone on each chicken breast.

6. Bake

Bake uncovered for 25–30 minutes, until the chicken reaches 165°F (74°C) and the cheese is melted and bubbly.

Optional: Broil for 1–2 minutes for a golden top — just watch it closely!

7. Rest and Serve

Let the dish rest for 5 minutes before serving. Garnish with parsley if you like.

Notes

Don’t rush the onions! Slow caramelizing gives the best flavor.
Even chicken thickness ensures juicy, perfectly cooked pieces.
Cheese swap: Gruyère makes it extra fancy and delicious.
Make ahead: Assemble up to 24 hours in advance and bake when ready.
