Ingredients

For the chicken
  • 1 piece chicken pieces (cut) (brined in 10% saltwater for 20 min, dried)
For the marinade
  • 0.5 cup orange juice (sour orange) (freshly squeezed)
  • 2 tbsp lager beer
  • 2 tbsp red wine
  • 1 tbsp pisco
  • 6 clove garlic
  • 1 tsp ground cumin (toasted) (toasted and ground)
  • 1 tsp paprika
  • 0.5 tsp black pepper (toasted and ground) (toasted and ground)
  • 1 tbsp yellow mustard
  • 1 tbsp ají panca paste
For the mashed potatoes
  • 4 piece potatoes (peeled, boiled)
  • 2 tbsp butter
  • 0.5 cup milk (warm)

Steps

  1. 1
    Brine the chicken pieces in a 10% salt solution for 20 minutes. Remove, do NOT rinse, and pat dry thoroughly.
    Tip: The brine seasons the chicken through and ensures juiciness. No additional salt is needed in the marinade because of this.
    ~20 min
  2. 2
    Make the marinade: blend together orange juice, beer, red wine, pisco, garlic, toasted cumin, paprika, toasted black pepper, yellow mustard, and ají panca paste using an immersion blender until smooth.
    Tip: This marinade keeps for a week refrigerated or 6-7 months frozen. Make extra and use it for rabbit, turkey, or grilled seafood.
    ~5 min
  3. 3
    Coat the brined and dried chicken pieces generously with the marinade. Let marinate for at least 30 minutes (overnight is better).
    Tip: Use a clean spoon to apply the marinade — never contaminate the batch with raw chicken.
    ~30 min
  4. 4
    Preheat oven to 200°C (400°F). Place chicken pieces on a baking tray and roast until golden brown and caramelized, about 35-45 minutes depending on piece size.
    Tip: The fructose in the orange juice helps achieve beautiful caramelization, but watch closely — it can burn if uncontrolled.
    ~40 min
  5. 5
    For the mashed potatoes: boil peeled potatoes until tender, drain, then mash with warm milk and butter until smooth and creamy. Season to taste.
    ~20 min
  6. 6
    Serve the roasted chicken pieces over or alongside the mashed potatoes. Spoon any pan juices over the chicken.

Cultural Context
This recipe reflects the heart of Peruvian home cooking — pollo al horno is a beloved everyday dish that every family has their own version of. Giacomo Bocchio, a renowned Peruvian chef and MasterChef judge, elevates the humble roast chicken with professional techniques: a 10% brine for moisture retention, a complex marinade using pisco (Peru's national spirit), ají panca (a dried Peruvian pepper), and orange juice for fructose-driven caramelization. He honors his grandfather Widow Bocchio's philosophy that '80% of a dish is the product, 20% is what the cook can do.'
