Ingredients

Instructions

  1. Step 1: Preheat your oven to 425°F. In a large mixing bowl, combine 3 tbsp olive oil, 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 1/2 tsp sea salt, 1 tsp black pepper, and 1 tbsp fresh lemon juice, stirring to create a marinade.
  2. Step 2: Add 6 bone-in, skin-on chicken thighs to the bowl and toss well to evenly coat each piece with the garlic-rosemary marinade.
  3. Step 3: In a large sheet pan, spread out 3 peeled and chunked carrots, 2 peeled and chunked parsnips, and 1 large red onion cut into wedges. Drizzle with a little olive oil and season with a pinch of salt and pepper, tossing to coat.
  4. Step 4: Nestle the marinated chicken thighs skin-side up among the vegetables on the sheet pan, ensuring pieces don’t overlap for even roasting.
  5. Step 5: Roast in the preheated oven for 35-40 minutes, until the chicken skin is golden and crispy and an instant-read thermometer inserted into the thickest part reads 165°F, and the vegetables are tender and caramelized.
  6. Step 6: Let rest 5 minutes before serving to allow juices to redistribute.
