Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a small bowl, combine zest and juice of 1 lemon, 2 tbsp chopped tarragon, 4 minced garlic cloves, 2 tbsp olive oil, 1 tsp sea salt, and 1/2 tsp black pepper to create a marinade.
  2. Step 2: Pat dry 6 bone-in, skin-on chicken thighs and rub the marinade all over each piece, ensuring even coverage. Let marinate at room temperature for 15 minutes.
  3. Step 3: While chicken marinates, toss 1 large sliced fennel bulb with 1 tbsp olive oil, 1/2 tsp salt, and 1/2 tsp black pepper. Spread fennel evenly on a large rimmed baking sheet.
  4. Step 4: Arrange chicken thighs skin-side up on top of the fennel wedges. Pour 1/4 cup water around the chicken to keep the fennel moist.
  5. Step 5: Roast in the preheated oven for 35-40 minutes until chicken skin is golden and crispy and internal temperature reaches 165°F, stirring fennel halfway through roasting to caramelize evenly.
  6. Step 6: Remove from oven and let rest 5 minutes before serving, spooning roasted fennel and pan juices over chicken.
