Ingredients

Instructions

  1. Step 1: Pat 2 boneless skinless chicken breasts dry and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 5-6 minutes per side until golden and cooked through (internal temperature 165°F), then remove and set aside.
  2. Step 2: Lower heat to medium and add 1 medium thinly sliced yellow onion to the skillet. Cook, stirring occasionally, for 10-12 minutes until deeply golden and caramelized.
  3. Step 3: Add 3 tbsp unsalted butter, 1 tbsp fresh thyme leaves, and 1 minced garlic clove to the onions, stirring for 1 minute until fragrant and butter melts.
  4. Step 4: Pour in 1/4 cup chicken broth, scraping the pan with a wooden spoon to release browned bits, and simmer for 3 minutes until the sauce slightly thickens.
  5. Step 5: Return chicken breasts to the skillet, spoon the onion-thyme butter sauce over them, and cook for 1-2 minutes to rewarm and coat the chicken before serving.
