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 browning too quickly.
3. Make the French Onion Sauce
Add thyme; cook 1-2 minutes until fragrant. Pour in wine (or broth), scraping browned bits from the bottom. Simmer 2-3 minutes until wine reduces. 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 gooey and bubbly. 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.

Variations
