In Summary
• A 1.6 to 2 kg chicken takes around 1 to 1.5 hours on a charcoal rotisserie at 180 to 200°C, and it is ready when the thickest part of the thigh reaches 75°C.
• Dry-brine the chicken overnight and truss it tightly, then centre it on the spit so it turns evenly.
• Bank the coals to the sides with a drip tray underneath, and add a chunk of fruitwood if you want a gentle smoky flavour.
A whole chicken of 1.6 to 2 kg takes around 1 to 1.5 hours to cook on a charcoal rotisserie at 180 to 200°C, and it is ready when the thickest part of the thigh reaches 75°C. Cooked that way, with steady indirect heat and the spit turning the whole time, you get the crisp, golden skin and juicy meat that have made charcoal chicken a backyard favourite. This guide covers how to prep and truss the bird, set up your coals, add flavour and judge when it is done.
Why Charcoal Suits Rotisserie Chicken
Charcoal gives off a strong, dry radiant heat that renders the fat under the skin and crisps it as the bird turns. Meanwhile the rotation keeps the chicken basting in its own juices, so the meat stays moist while the outside browns evenly on every side. The coals also add a light smokiness that gas struggles to match, which goes a long way to explaining why charcoal chicken shops have become a fixture across Sydney’s suburbs.
Choosing and Prepping the Chicken
Look for a whole chicken of around 1.6 to 2 kg, usually sold as a size 16 to 20. Free-range birds tend to have a little more flavour, although any good-quality chicken will cook well. The night before, pat the chicken dry and season it all over with salt. Leave it uncovered overnight on a tray on the bottom shelf of the fridge. This dry brine seasons the meat right through and dries out the skin, which is the key to getting it crisp.
Before it goes on the spit, truss the chicken by tying the legs together with butcher’s twine and tucking the wing tips in tight against the body. A neatly trussed bird holds its shape as it turns, and the wings and drumsticks are less likely to flop about and burn.
Getting the Chicken on the Spit
Slide the spit rod through the cavity from the neck end to the tail, keeping it as close to the centre of the bird as you can. Push the forks in firmly at each end and tighten them down, then turn the spit by hand a few times to check the balance. If one side keeps dropping to the bottom, reposition the chicken until it turns smoothly, because an off-centre bird puts strain on the motor and cooks unevenly. Most spits hold two chickens comfortably, which is handy when you are feeding a crowd. Push the birds snugly together with a fork holding each end.
Setting Up Your Charcoal
Rotisserie chicken needs indirect heat. Bank the coals in two rows along either side of the chicken, or in a single row behind it on a kettle, and set a drip tray directly underneath to catch the fat. Around 2 to 3 kg of charcoal is plenty for one or two birds. Light it in a charcoal chimney and wait until the coals are covered in grey ash, which usually takes 15 to 20 minutes, then spread them into position. Aim for 180 to 200°C at the level of the chicken, measured with a thermometer near the spit.
For a gentle smoky flavour, add a chunk or two of fruitwood such as apple or cherry once the coals have settled. Many cooks also put a few halved potatoes in the drip tray so they roast in the chicken drippings, which gives you a side dish with no extra effort.
Flavour Ideas
Salt and a little olive oil are all a good chicken needs over charcoal, though there is plenty of room to experiment.
• Lebanese-style: garlic, lemon, paprika and a pinch of allspice, served with toum and pickles.
• Peri peri: a baste of chilli, garlic, lemon juice and paprika, brushed on during the last half hour.
• Herb butter: softened butter mixed with thyme and lemon zest, pushed under the skin before cooking.
• Sticky glaze: honey and soy with a little garlic, brushed on in the final 15 minutes.
Keep any sugary glazes and sauces for the last 15 to 20 minutes so they caramelise without burning.
Cooking Time and Temperature
At 180 to 200°C, a 1.6 to 2 kg chicken usually takes around 1 to 1.5 hours, with two birds on the spit taking a little longer. Wind and the size of the chicken can both shift the timing, so use a meat thermometer to decide when it is ready. Check the thickest part of the thigh without touching the bone, and take the chicken off once it reads 75°C, which is the safe cooking temperature for poultry recommended by healthdirect. The juices should run clear and the legs should move loosely in their joints. If the skin needs more colour near the end, add a few freshly lit coals to lift the heat for the final 15 minutes.
Resting and Carving
Let the chicken rest for 10 to 15 minutes before carving so the juices settle back into the meat. Slide it off the spit with tongs and a carving fork and cut away the twine. Carve the legs and thighs first, then the wings and breast. Serve it with the drip tray potatoes and a fresh salad, or pile the meat into warm flatbread with garlic sauce for charcoal chicken at its simplest.
Common Mistakes to Avoid
• Wet skin: skipping the dry brine or the pat-down leaves the skin soft and pale.
• Loose trussing: floppy wings and legs burn before the rest of the bird is cooked.
• Coals directly underneath: dripping fat causes flare-ups that scorch the skin.
• Guessing doneness: a thermometer takes the risk out of undercooked chicken.
• Carving straight away: a short rest keeps the meat juicy.
FAQs
How long does rotisserie chicken take over charcoal?
Around 1 to 1.5 hours for a 1.6 to 2 kg chicken at 180 to 200°C. Check that the thickest part of the thigh has reached 75°C before serving.
How much charcoal do I need?
About 2 to 3 kg covers one or two chickens. Keep a few extra coals on hand so you can lift the heat near the end for crisper skin.
Do I need to baste rotisserie chicken?
Basting is optional, since the turning spit keeps the chicken coated in its own juices. If you want extra flavour, brush on butter or a sauce in the last 20 minutes.
Can I cook two chickens at once?
Yes, most spits hold two birds comfortably as long as both are trussed tightly and pushed snugly together on the rod. Allow a little extra cooking time when the spit is fully loaded.
Why is my chicken skin not crispy?
The usual causes are skin that was too wet going on or heat that was too low. Dry-brining the chicken uncovered overnight makes a big difference, and a hotter fire for the final 15 minutes will finish the job.
A Last Word
Rotisserie chicken over charcoal is one of the easiest and most rewarding cooks you can do on a spit. Dry-brine the bird the night before and keep the coals to the sides, and once the thigh reaches 75°C you will have crisp skin and juicy meat ready to carve.

Glossary
• Dry brine: Salting meat ahead of cooking and leaving it uncovered in the fridge to season the meat and dry out the skin.
• Trussing: Tying a bird’s legs and wings close to its body with twine so it holds its shape and cooks evenly.
• Spit forks: The pronged clamps that hold the meat firmly in place on the spit rod.
• Indirect heat: Coals placed to the sides of or behind the food, leaving the area directly beneath it clear.
• Drip tray: A tray under the meat that catches fat and juices to help prevent flare-ups.
