Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium heat. Season 2 chicken breasts with 1 tsp salt and 1/2 tsp black pepper, then add them to the skillet. Sear for 5-6 minutes per side until golden brown and cooked through, then remove from pan and keep warm.
  2. Step 2: In the same skillet, add 1 large thinly sliced yellow onion and 3 minced garlic cloves. Sauté over medium-low heat for 15 minutes, stirring occasionally, until onions are deeply caramelized and fragrant.
  3. Step 3: Stir in 1/4 cup balsamic vinegar and 1 tbsp brown sugar, cooking for 3-4 minutes until the sauce thickens and coats the onions. Add 1 tsp chopped fresh thyme and return the chicken breasts to the pan, spooning the glaze over them for 2 minutes before serving.
