What You’ll Need

3–4 boneless, skinless chicken breasts
2 large yellow onions, thinly sliced
2 tablespoons butter
1 teaspoon sugar
1/2 teaspoon garlic powder
1/2 teaspoon thyme
1/2 cup beef broth (low sodium preferred)
1 tablespoon balsamic vinegar (optional for depth)
1 1/2 cups shredded mozzarella or provolone cheese
Salt and pepper to taste
Fresh parsley for garnish

How to Make It

Preheat your oven to 375°F (190°C).
In a large skillet, melt butter over medium heat. Add sliced onions and sugar. Cook low and slow for about 20–25 minutes, stirring occasionally, until onions are soft, golden, and caramelized.
Add garlic powder, thyme, beef broth, and balsamic vinegar to the onions. Simmer for 3–4 minutes until slightly reduced.
Season the chicken breasts with salt and pepper, then place them in a baking dish.
Pour the onion mixture over the chicken, spreading evenly.
Top with shredded cheese and bake uncovered for 25–30 minutes, or until the chicken is cooked through (internal temp should be 165°F).
Broil for an additional 2–3 minutes if you want a golden cheesy top.
Garnish with chopped parsley and serve hot.
