Ingredients

• 4 boneless, skinless chicken breasts

• 2 tablespoons butter
• 2 cloves garlic, minced
• 1 teaspoon fresh thyme (or 1/2 teaspoon dried)

How to make French Onion Chicken

1. In a large skillet, melt butter over medium heat. Add onions and cook slowly for 15–20 minutes until golden brown, stirring often. Add garlic and thyme; cook 1 more minute. Deglaze with beef broth and balsamic vinegar, scraping up browned bits. Simmer for 2 minutes.
2. Season chicken with salt and pepper. In another skillet (or the same if large enough), heat olive oil over medium-high heat. Sear chicken 3–4 minutes per side until golden.
3. Transfer chicken to a baking dish. Spoon caramelized onions and broth mixture over the chicken. Sprinkle with shredded cheese.
4. Bake at 375°F (190°C) for 15 minutes, or until chicken is cooked through (165°F internal temp) and cheese is bubbly.
5. Serve warm with mashed potatoes, rice, or bread to soak up all that savory onion sauce.
