Instructions

  1. Step 1: Pat 6 bone-in chicken thighs dry and season evenly with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 3 tbsp olive oil in a large heavy-bottomed skillet over medium heat. Add the chicken thighs skin-side down and sear for 5 minutes until skin is golden brown, then flip and cook 3 minutes more. Remove chicken and set aside.
  3. Step 3: Lower heat to low and add 2 large thinly sliced yellow onions to the skillet. Stir in 2 tbsp butter and cook onions slowly for 15 minutes, stirring occasionally, until deeply caramelized and fragrant.
  4. Step 4: Add 3 minced garlic cloves and 4 sprigs of fresh thyme to the onions, cooking for 1 minute until aromatic.
  5. Step 5: Return the chicken thighs to the skillet and pour in 1 1/2 cups chicken broth. Cover and simmer gently over low heat for 35-40 minutes until chicken is tender and cooked through.
  6. Step 6: Remove thyme sprigs and adjust seasoning with salt and pepper to taste before serving.
