Ingredients

Instructions

  1. Step 1: In a large bowl, whisk together 1/2 cup lemon juice, 3 tbsp Dijon mustard, 4 minced garlic cloves, 1/4 cup vegetable oil, 2 tsp salt, 1 tsp black pepper, and 2 tbsp white vinegar to create the marinade. Add 6 chicken thighs and toss to coat. Cover and refrigerate for at least 3 hours or overnight to tenderize and infuse flavor.
  2. Step 2: Heat a large skillet over medium heat and add 1 tbsp vegetable oil. Add 3 medium thinly sliced yellow onions with 2 bay leaves and 1/4 cup water. Cook slowly, stirring occasionally, for 20-25 minutes until onions are deeply caramelized and soft, adding a splash of water if they start to stick.
  3. Step 3: Preheat grill or grill pan to medium-high heat (about 400°F). Remove chicken from marinade and grill the 6 chicken thighs for about 6-7 minutes per side, until skin is crisp and internal temperature reaches 165°F.
  4. Step 4: Transfer grilled chicken to a serving platter and spoon the caramelized onions over the top, letting the tangy sauce from the marinade and onions mingle. Serve hot with steamed rice or couscous.
