Full Recipe:

Ingredients

• 2 boneless, skinless chicken breasts (about 1¾ lb / 790 g)

• ½ teaspoon salt, plus more to taste

• ½ teaspoon ground black pepper

• ½ cup (60 g) all‑purpose flour

• 2 tablespoons olive oil (plus more if needed)

• 1 tablespoon salted butter

• 2 large yellow onions (about 700 g), thinly sliced

• 2 cloves garlic, minced 

• 1½ cups (360 mL) beef broth

• 2 teaspoons Worcestershire sauce

• 1 teaspoon fresh thyme leaves (or ½ tsp dried)

• 4 oz (approx. 113 g) grated Gruyère or Swiss cheese 

Directions

1. Prep & dredge: Slice chicken breasts lengthwise into 4 cutlets, pound to about ¾‑inch thickness. Season with salt and pepper on both sides. Dredge in flour, shaking off excess. 

2. Sear chicken: Heat olive oil in a large (12") oven‑safe skillet over medium‑high. Sear chicken 3 minutes per side until golden, then transfer to a plate. 

3. Caramelize onions: In same skillet, add butter and remaining oil. Add onions and remaining salt. Cook ~10 minutes over medium-high until softened, then reduce heat and stir frequently ~10 more minutes until deeply golden. Add garlic in final minute.

4. Make sauce: Sprinkle remaining flour over onions; stir 1 minute. Gradually whisk in beef broth and Worcestershire sauce until smooth. Stir in thyme and remaining salt & pepper. Simmer until slightly thickened. 

5. Finish chicken: Return chicken to skillet, submerging slightly in sauce. Simmer until chicken reaches 165°F (~2 minutes). Remove from heat. 

6. Broil cheese: Preheat broiler. Sprinkle cheese evenly over chicken and onions. Broil 3–5 minutes until cheese melts and bubbles. Garnish with extra thyme and serve.
