Low & slow on a kamado — the practical session guide
A kamado promises everything a low & slow cook could want, and it punishes beginners harder than any other cooker. The ceramic walls are the superpower and the trap in one: they hold heat so well that steering is slow and an overshoot is hard to undo. This guide skips the basics on purpose — what a kamado is and which rubs suit it is covered elsewhere. This is the practical session guide: how to set up a kamado for low & slow, how to prevent overshoot, how to manage a long session, and how to come out the other side with the best bark you have ever pulled off a grill.
First read Kamado BBQ tips — everything you need to know for the general setup and temperature chart. This guide is specifically about low & slow sessions of 4 hours and longer.
The deflector plate: how and where to place it
The deflector plate — heat deflector or plate setter in some manuals — is the piece that turns your kamado from a direct grill into an indirect oven. Without it, radiant heat from the coals hits the meat from below, and that is searing weather, not low & slow. With it, hot air circulates gently around the meat without direct radiation.
The plate goes under the grill grate, resting on the firebox rim or on its dedicated holders, depending on the brand. The legs point upwards on a Big Green Egg and downwards on some other brands; check your kamado's manual. The grate then sits on the plate, and the meat on the grate.
Most kamados ship with a ceramic plate. Cast-iron plates exist and hold even more heat, which helps on long sessions but makes overshoot more likely during setup. For low & slow, ceramic is the safe choice.
Over a long session, fat drips onto the plate and burns slowly; if the plate runs too hot, that can turn into bitter smoke. Lay a loose sheet of aluminium foil over the plate or set a drip pan on it to catch the fat, without blocking the airflow around the plate.
Heat soak: the step most beginners skip
Heat soak means letting the whole kamado stabilise at the target temperature — ceramic walls, deflector plate and grill grate included — before the meat goes in. It is the most skipped step in the book, and the one that changes the most.
Why it matters: drop meat into a kamado that has just reached temperature and the still-cold ceramics pull heat out of the air. The temperature sags, sometimes by 10–20°C, you open the vents to chase it, and before you know it you are in overshoot territory. Almost every troubled session starts with an impatient heat soak.
Once you hit the target — say 120°C for pulled pork — hold that temperature for at least 15–20 minutes before the meat goes in. On a large (XL) kamado or in cold weather, give it 25–30 minutes. You want the temperature steady, not climbing or falling. Only then does the meat go in.
Preventing and correcting overshoot
Overshoot — the kamado running hot while you try to coax it back down — is the great frustration of low & slow on a kamado. The ceramic walls hold heat so well that a kamado sitting 30°C above target can take an hour to come back down.
Set the vents conservatively and always climb to the target temperature, never descend to it. Start with both vents nearly closed and open them step by step. A kamado that creeps up to 120°C is easy to stabilise; one you have to drag back from 160°C is not.
Too hot? Close the bottom vent almost fully, leaving only a sliver of air. Set the top vent to a quarter open. Wait 10–15 minutes before judging whether more adjustment is needed. Never close both vents completely: you will smother the fire and trade clean smoke for bitter smoke.
Warming a kamado is easy. Cooling one takes time. Always work from low to high, never the reverse — and in low & slow more than anywhere, because the gap between "good" and "too hot" is small.
Managing long sessions: refueling and fuel
A kamado sips fuel compared with a kettle, but for sessions of 10–14 hours (brisket, pulled pork) refueling is still part of the plan, and the ceramic walls change how you do it.
Fill the firebox completely for sessions of 8+ hours with Kokoko Eggs or Quebracho briquettes. A full firebox of Kokoko Eggs on a standard Large kamado holds 8–10 hours at 110–120°C. Lump charcoal burns faster and gives 5–6 hours. For a brisket of 12+ hours: use briquettes and plan one refuel.
Unlike a kettle, you can add cold fuel to a kamado without a major temperature crash — the ceramic walls hold so much heat that the temperature dips only 5–10°C and recovers within 5–10 minutes. Slide the new fuel in along the edge of the glowing coals rather than on top, open the vents a little wider briefly, and set them back once the temperature steadies.

The stall on a kamado: different from a kettle
The stall — the stretch where the core temperature flatlines because of evaporative cooling — happens on a kamado too, but two things differ from a kettle or an offset smoker.
The stall lasts longer on a kamado. The closed, humid chamber slows evaporation from the meat's surface; humidity inside a kamado runs higher than in an open offset smoker. That means a longer stall, but also less moisture loss. Budget 3–5 hours of stall for a large brisket on a kamado.
Wrapping works differently too. Most pitmasters reach for butcher paper rather than foil on a kamado: foil in the already-humid chamber steams the bark into mush. Butcher paper breathes and compensates better. For pulled pork, foil is perfectly fine.

Bark on a kamado: how to maximize it?
A kamado naturally builds a thicker, deeper bark than a kettle, thanks to stable temperatures, low airflow and the closed chamber. A few deliberate choices push it further.
Apply the rub at least 4 hours ahead, or the evening before the session. The closed, humid environment draws the spices deeper into the meat, and the pellicle — the slightly tacky surface that forms after a longer rub rest — gives the smoke flavour and rub a better grip.
A kamado holds smoke longer than an open grill. Two wood chunks are enough for most full low & slow sessions; more quickly turns bitter, because the smoke has no direct escape and lingers around the meat. Less is more.
Every peek costs heat, and the built-up smoke environment with it. The bark of the first 3–4 hours forms in that stable, smoky chamber, so open the lid only when you truly must: to wrap at the stall and for the doneness test at the end.
