Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Pat 1.5 lbs chicken thighs dry with paper towels, then rub with 3 tbsp harissa paste, 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper.
  2. Step 2: Heat a large oven-safe skillet over medium-high heat. Add 2 tbsp olive oil, then cook 2 thinly sliced yellow onions for 8-10 minutes until golden and deeply caramelized, stirring occasionally.
  3. Step 3: Push onions to the edges of the skillet, add chicken thighs skin-side down, and cook for 5 minutes until golden brown. Sprinkle 3 minced garlic cloves and 1 tsp smoked paprika over onions.
  4. Step 4: Transfer skillet to oven and roast for 25 minutes, or until chicken reaches 165°F (74°C) internally and skin is crisp.
  5. Step 5: Let rest for 5 minutes before serving, spooning caramelized onions and pan juices over the chicken.
