🧅 Ingredients You’ll Need
For the Chicken:
- 3–4 boneless, skinless chicken breasts
- Salt and black pepper, to taste
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme (or Italian seasoning)
- 1 tablespoon olive oil
For the French Onion Mixture:
- 3 large yellow onions, thinly sliced
- 3 tablespoons butter
- 1 teaspoon sugar (helps with caramelizing)
- 2 cloves garlic, minced
- 1 cup beef broth (or chicken broth)
- 1 tablespoon flour (optional, for thickening)

For the Topping:

🍽️ Step-by-Step Method
Step 1 — Prepare the Chicken
- Pat the chicken breasts dry with paper towels.
- Season both sides with salt, pepper, garlic powder, and dried thyme.
- Heat 1 tablespoon of olive oil in a skillet over medium-high heat.
- Sear the chicken for 2–3 minutes per side — just enough to give it some color.
- Remove the chicken and set aside.
Tip: Searing locks in flavor but doesn’t cook the chicken fully yet.
Step 2 — Caramelize the Onions
This is the heart of the dish.
- In the same skillet, melt the butter.
- Add the sliced onions and sprinkle with sugar.
- Cook on medium heat for 20–25 minutes, stirring occasionally, until the onions turn deep golden brown.
- Add the minced garlic and cook for 1 more minute.
- Sprinkle the flour and stir — this will help slightly thicken the mixture (optional).
- Pour in the beef broth and Worcestershire sauce.
- Let it simmer for 3–5 minutes until the mixture reduces slightly and becomes rich and glossy.
Step 3 — Assemble the Bake
- Preheat the oven to 400°F (200°C).
- Spread half of the caramelized onion mixture into the bottom of a baking dish.
- Place the seared chicken breasts on top.
- Spoon the remaining onions over the chicken.
- Pour any leftover broth mixture around the edges of the dish.
