🛒 Ingredients

8 servings

8
  • 1 kg (2.2 lbs) chicken thighs and drumsticks
  • 2 packets of dry onion soup mix
  • 300 g (1¼ cups) mayonnaise
  • A drizzle of olive oil
  • Freshly ground black pepper, to taste

Directions

  1. 1

    Preheat your oven to 180 °C (350 °F). Rinse the chicken pieces under cold water and pat them completely dry with paper towels.

  2. 2

    Pour the onion soup mix into a shallow dish. Coat each piece of chicken thoroughly in the mix, pressing gently so the seasoning sticks to every surface.

  3. 3

    Arrange the coated pieces snugly in a lightly oiled baking dish — keeping them close together helps retain moisture during the long roast.

  4. 4

    Spread a generous layer of mayonnaise over the top and sides of each piece using a spoon or spatula.

  5. 5

    Roast for approximately 2 hours until deep golden brown and the juices run clear. Cover loosely with foil halfway through if the top browns too quickly.

💡 Chef's Tip

For maximum flavor, let the chicken rest coated in the onion mix in the refrigerator for up to 1 hour before adding the mayonnaise. Pairs beautifully with mashed potatoes or roasted vegetables.
