Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 large thinly sliced yellow onion and cook, stirring occasionally, for 12 minutes until golden brown and caramelized.
  2. Step 2: Season 2 chicken breasts (6 oz each) with 1 tsp salt and 1/2 tsp black pepper. Push onions to the side and add chicken breasts to the skillet. Sear for 5 minutes on each side until golden and cooked through.
