Instructions
1. Season and Cook the Chicken
Season chicken breasts with salt, pepper, garlic powder, and onion powder. Heat olive oil and butter in a large skillet over medium-high heat. Add chicken and cook for 5-6 minutes per side, until golden brown and cooked through (internal temperature 165°F). Remove and set aside.
2. Caramelize the Onions
Reduce heat to medium; add butter to the skillet. Add sliced onions, salt, pepper, and sugar (if using). Stir to coat. Cook for 20-25 minutes, stirring frequently, until soft, golden, and caramelized. Lower heat if needed to prevent burning.
3. Make the French Onion Sauce
Add thyme; cook 1-2 minutes. Pour in wine (or broth), scraping up browned bits. Simmer 2-3 minutes. Add beef broth and Worcestershire sauce; simmer 5 minutes until slightly thickened.
4. Combine Chicken and Sauce
Return chicken to the skillet, nestling it in the sauce. Spoon sauce over chicken. Sprinkle with cheese.
5. Melt the Cheese
Cover and reduce heat to low; melt cheese for 3-5 minutes, until bubbly and gooey. Alternatively, broil for 2-3 minutes (if skillet is oven-safe).
6. Garnish and Serve
Remove from heat. Garnish with parsley (optional). Serve warm with mashed potatoes, crusty bread, or pasta.
Cooking Notes
- Onion Caramelization: Slow caramelization (20-25 minutes) develops the best flavor. Stir often and use moderate heat.

- Broth Options: Beef broth is best, but chicken broth can be substituted.
Variations
- Mushroom French Onion Chicken: Add sliced mushrooms with the onions.
- Herb-Crusted French Onion Chicken: Add fresh rosemary or more thyme.
- Creamy French Onion Chicken: Stir in 1/4 cup heavy cream or sour cream before adding the chicken.
