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 temp 165°F). Remove and set aside.
2. Caramelize the Onions
Reduce heat to medium. Add butter to the skillet, then add sliced onions, salt, pepper, and sugar (if using). Cook, stirring frequently, for 20-25 minutes until soft, golden, and caramelized. Lower heat if needed to prevent burning.
3. Make the French Onion Sauce
Add thyme and cook for 1-2 minutes. Pour in wine (or broth), scraping up browned bits. Simmer for 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 gooey and bubbly. Alternatively, broil (if skillet is oven-safe) for 2-3 minutes for extra bubbly cheese.
6. Garnish and Serve
Remove from heat. Garnish with parsley (optional). Serve warm with mashed potatoes, crusty bread, or pasta.

- Onion Caramelization: Patience is key! It takes time for that deep flavor.

Variations
- Mushroom: Add sliced mushrooms with the onions.
- Herb-Crusted: Add fresh rosemary or more thyme.
- Creamy: Stir in 1/4 cup heavy cream or sour cream before adding the chicken.
