Buttermilk-Brined Roast Chicken
Overnight brining. Impossibly juicy. Golden skin that shatters. Worth every minute of patience.
The FODMAP swaps
Roast chicken is one of the most naturally FODMAP-friendly dishes. Two small swaps handle the buttermilk and the garlic.

Ingredients
- 1.5–2 kgWhole chicken
- 480mlLactose-free buttermilk (or lactose-free yoghurt thinned with water)
- 2 tspFine salt
- 1 tspBlack pepper, freshly ground
- 2 tbspGarlic-infused olive oilSafe swap for garlic ↗
- 1Lemon, halved
- Small bunchFresh thyme sprigs
Method
- 1Brine overnight
Combine lactose-free buttermilk, salt, and pepper in a large bowl or zip-lock bag. Add the chicken and ensure it is well submerged. Refrigerate for at least 8 hours, up to 24. The longer the better.
- 2Bring to room temperature
Remove chicken from the brine 1 hour before roasting. Pat thoroughly dry with kitchen paper — this is the key to crispy skin. Discard the brine.
Key tip: A dry surface is essential for browning. Don't skip the patting dry step. - 3Roast
Preheat oven to 220°C (200°C fan). Rub the chicken all over with garlic-infused oil and tuck thyme under the skin and in the cavity. Roast breast-side up for 60–75 minutes until the skin is deep golden and juices run clear.
- 4Rest, then serve
Rest uncovered for 10 minutes before carving. Squeeze lemon generously over the bird just before serving. Resting lets the juices redistribute — don't skip it.
