Ingredients

Instructions

  1. Step 1: In a large bowl, combine 3 large thinly sliced yellow onions, 1/3 cup fresh lemon juice, 4 minced garlic cloves, 2 tbsp Dijon mustard, 1 1/2 tsp salt, and 1 tsp black pepper. Add 2 lbs bone-in, skin-on chicken thighs and mix well to coat. Cover and marinate in the refrigerator for at least 2 hours or overnight for best flavor.
  2. Step 2: Heat 3 tbsp vegetable oil in a large heavy-bottomed skillet over medium-high heat. Remove chicken from marinade (reserve marinade with onions) and sear the chicken thighs skin-side down for 6-7 minutes until golden brown and crispy, then flip and cook for another 5 minutes. Remove chicken and set aside.
  3. Step 3: Reduce heat to medium and add the reserved onion marinade with 1 cup chicken broth, 2 bay leaves, and 1 whole scotch bonnet pepper if using. Stir and cook for 10 minutes until the onions are soft and the sauce slightly thickens.
  4. Step 4: Return the chicken thighs to the skillet, nestling them into the onion mixture. Cover and simmer on low heat for 30-35 minutes until chicken is tender and cooked through, stirring occasionally to coat the chicken with sauce.
  5. Step 5: Remove bay leaves and scotch bonnet pepper before serving. Serve hot over steamed white rice or couscous.
