Instructions

  1. Step 1: Pat dry 2 skinless chicken breasts (about 6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering, then add chicken breasts and cook for 6 minutes without moving until golden brown on one side.
  3. Step 3: Flip the chicken breasts and cook for another 5 minutes until cooked through and juices run clear; transfer chicken to a plate and cover loosely with foil.
  4. Step 4: Reduce heat to medium, add 1 thinly sliced medium yellow onion to the same skillet and cook, stirring occasionally, for 8 minutes until soft and caramelized.
  5. Step 5: Add 3 tbsp unsalted butter, 3 minced garlic cloves, and 1 tsp fresh thyme leaves to the onions; sauté for 2 minutes until fragrant and butter melts into a silky sauce.
  6. Step 6: Return the chicken breasts to the skillet, spoon the onion and garlic herb butter over them, and cook for 1 more minute to rewarm and meld flavors before serving.
