Ingredients
Scale
- 4 boneless, skinless chicken breasts (about 1½ pounds or 680g)
- 3 large yellow onions (about 2 pounds or 900g), thinly sliced
- 2 tablespoons (30g) unsalted butter
- 1 tablespoon (15ml) olive oil
- 2 cloves garlic, minced
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried)
- 1 cup (240ml) beef broth (low-sodium preferred)
- ½ cup (120ml) dry white wine (can substitute additional broth)
- 1 tablespoon (15ml) Worcestershire sauce
- 1½ cups (170g) Gruyère cheese, shredded (Swiss cheese works as a substitute)
- Salt and freshly ground black pepper, to taste
- 1 tablespoon all-purpose flour
- Fresh parsley, chopped (for garnish)
Instructions
- Pat chicken breasts dry and season with salt and pepper on both sides. Slice onions thinly.
- Heat butter and olive oil in a large oven-safe skillet over medium heat. Add onions and a pinch of salt, reduce heat to medium-low. Cook for 25-30 minutes, stirring occasionally, until deeply caramelized. Add garlic and thyme during the last 2 minutes.
- Transfer caramelized onions to a plate, leaving the oil in the pan.
- Increase heat to medium-high and add chicken breasts to the skillet. Sear until golden brown, about 4-5 minutes per side. Transfer chicken to a plate.
- Reduce heat to medium, add white wine to the pan and scrape up browned bits. Let reduce by half, about 2-3 minutes. Sprinkle in flour and whisk for 30 seconds. Add beef broth and Worcestershire sauce, whisking until smooth. Simmer 2-3 minutes until slightly thickened.
- Return caramelized onions to the pan and stir to combine with sauce. Nestle chicken breasts into the onion mixture.
- Preheat broiler. Top each chicken breast with Gruyère cheese. Broil for 2-3 minutes until cheese is melted and lightly browned.
- Let rest 5 minutes, garnish with parsley, and serve with plenty of onion sauce spooned over each portion.
