Instructions

  1. 1

    1. Preheat the oven to 220 °C / 425 °F. Pat the chicken thighs dry with paper towels and season both sides with 5 g salt, black pepper, and smoked paprika.

  2. 2

    2. Heat 1 tablespoon olive oil in a large skillet over medium heat. Place the chicken skin-side down and sear for 4 to 5 minutes until the skin is deeply golden. Turn and cook 2 minutes more. Transfer the chicken to a plate.

  3. 3

    3. In the same skillet, add the remaining tablespoon of olive oil and the onion. Cook over medium heat for 8 to 10 minutes, stirring, until very soft and golden. Add the garlic and cook for 30 seconds.

  4. 4

    4. Add the balsamic vinegar, honey, unsweetened cocoa powder, and chicken stock. Add the remaining salt and cook for 2 to 3 minutes, stirring, until the sauce is glossy and slightly thickened.

  5. 5

    5. Transfer the chicken to a baking dish or oven-safe skillet, skin-side up. Spoon the onion-balsamic glaze over and around it. Bake for 22 to 25 minutes at 220 °C / 425 °F, or until the chicken is fully cooked.

  6. 6

    6. While the chicken bakes, place the sweet potatoes in a pot with cold water and bring to a boil. Cook for 15 to 18 minutes until very tender. Drain well.

  7. 7

    7. Mash the sweet potatoes with the butter, warm milk, apple cider vinegar, and half of the chives until rustic but creamy. Adjust salt if needed.

  8. 8

    8. Let the chicken rest for 5 minutes after baking. Serve a bed of sweet potato mash, top with the chicken, and finish with the onion sauce from the pan and the remaining chives.

Chef tips

For a deeper glaze, reduce the sauce 1 extra minute before baking. Do not scorch the cocoa: it should dissolve into the sauce rather than toast on its own. If using boneless thighs, start checking for doneness a few minutes earlier.

Substitutions

You can use skinless chicken thighs for a lighter version. Sweet potatoes can be replaced with pumpkin or starchy potatoes. Honey can be swapped for maple syrup, and chives for fresh parsley.
