This beer can brined roast chicken comes out incredibly juicy inside with crisp, deeply seasoned skin. An overnight brine and a simple sweet-spicy rub give the bird plenty of flavor, making it a great centerpiece for a weekend dinner or casual gathering.
Make the brine: combine 3.5 liters water, salt, caster sugar, bay leaves, mustard seeds, and black peppercorns in a large saucepan. Bring to a boil, stirring until the salt and sugar dissolve. Transfer to a large bowl or food-safe container, add the sliced lemons, and let the brine cool completely. Cover and chill for at least 2 to 3 hours.
Submerge the chicken in the cold brine, making sure it is fully covered. Cover and refrigerate for 8 to 12 hours. Do not leave it longer than 12 hours or the chicken may become overly salty.
Remove the chicken from the brine and pat it very dry with paper towels. Set it on a rack over a roasting tin and refrigerate uncovered for 6 to 8 hours to help dry the skin for better browning. Take the chicken out of the refrigerator 30 minutes before roasting.
Heat the oven to 200C/180C fan/gas 6. In a small bowl, mix the olive oil, maple syrup, cayenne pepper, ground cumin, and black pepper. Pour out about half of the beer and place the half-full can in the center of a deep baking tray. Rub the seasoning mixture all over the chicken, then carefully sit the chicken upright over the can so the can fits securely inside the cavity.
Roast for 1 hour to 1 hour 20 minutes, checking every 15 minutes to make sure the chicken remains stable. The chicken is done when a thermometer inserted into the thickest part of the thigh, away from the bone, reads 70C. Carefully lift the chicken off the can, loosely tent with foil, and rest for 10 minutes before carving and serving.
For the best texture, do not skip the uncovered chilling step; it helps the skin crisp in the oven. If you prefer a milder finish, reduce the cayenne to 1 tsp. Leftover chicken keeps well in an airtight container in the refrigerator for up to 3 days.
