Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1 lb Brussels sprouts and 6 smashed garlic cloves with 2 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper until evenly coated.
  2. Step 2: Pat dry 6 bone-in, skin-on chicken thighs with paper towels, then rub with 1 tbsp olive oil, 1 tsp smoked paprika, 1/2 tsp sea salt, and 1/4 tsp black pepper.
  3. Step 3: Arrange the chicken thighs skin-side up on a large rimmed baking sheet, spacing apart. Scatter the Brussels sprouts and garlic around the chicken.
  4. Step 4: Roast in the preheated oven for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F and the Brussels sprouts are tender and caramelized, turning the sprouts halfway through.
  5. Step 5: Remove from oven and sprinkle 1 tbsp chopped fresh thyme over the dish before serving.
