Offset smokers are a beloved choice for barbecue enthusiasts who crave authentic, slow-smoked meats with deep, smoky flavour and a perfectly charred bark. This traditional design requires some practice to master, but the results are well worth the effort.
Below we've outlined simple, easy-to-follow steps to start your offset smoking journey. And if you’re operating offset smokers in the UK, we’ve also added some useful tips for maintenance and weather protection to help you get the most out of your pit for years to come.
How Do Offset Smokers Work?
Unlike direct grilling, offset smokers cook food indirectly by placing it in a main cooking chamber, while the fire burns separately in a connected firebox off to the side.
This setup relies on convective heat - heat and smoke flow from the firebox, through the cooking chamber, and out the chimney, gently cooking the meat with steady, consistent heat and rich smoke infusion. The offset design allows for excellent capacity, great temperature control, and versatility, making it ideal for everything from ribs and brisket to whole poultry.
- Firebox: Burn seasoned hardwood in a dedicated firebox.
- Main Chamber: Food rests on grates away from direct heat.
- Airflow Control: Adjust the firebox vents and chimney damper to regulate temperature and smoke intensity.
- Smoke Flow: Smoke travels horizontally from firebox through cooking chamber to chimney, imparting flavour.
Choosing the Right Wood for Smoking
The choice of wood is critical to the flavour profile of your smoked food. We recommend experimenting with different types of wood and split sizes for different cooks. This will help determine how much wood you need to add to the fire in order to reach a certain cooking temperature.
Top tips on what type of wood is best for smoking:
- Hardwoods Only: Use seasoned hardwood like oak, hickory, maple, apple, or cherry.
- Wood Type & Meat Pairing:
- Oak and hickory: Best for beef and game, strong smoky flavor.
- Fruitwoods (apple, cherry): Milder, sweeter smoke suited for poultry and pork.
- Avoid Softwoods: Pines and firs contain resins that produce harsh, unpleasant smoke and toxins.
- Seasoning and Moisture Content: Aim for wood dried for at least 12 months or kiln-dried with less than 20% moisture content. Too wet, and the wood smoulders, causing bitter flavours and unstable pit temperatures.
Using a moisture meter can help determine if your wood is ready to burn, or if needs time to season and dry out further.
Starting Your Fire
To ensure your fire burns continuously and any new wood splits catch alight easily, you need to maintain a good bed of hot coals. This can happen automatically as the wood burns down, but it’s generally easier to build the initial fire with a bed of lump charcoal underneath the splits of wood.
We recommend starting your fire with a high-powered propane blowtorch to get the pit up to temperature quickly. You can of course use natural fire lighters, but the downside of waiting up to an hour for the pit to reach appropriate cooking temperatures.
Temperature Control in an Offset Smoker
Maintaining consistent temperature is key to successful smoking and perfectly cooked food.
Fuel & Fire Management:
- Larger splits burn slower; smaller splits ignite easier.
- Build a hot coal bed beneath wood for stable heat.
- Adding wood every 45-90 minutes helps keep temperature steady.
- If temperatures start to drop, top the fire up with new splits of wood
- Starting with lump charcoal underneath the wood speeds fire start up.
Airflow Controls:
- Open firebox vents for more oxygen → hotter fire.
- Close vents partially to reduce oxygen → lower temp.
- Adjust chimney damper to fine-tune airflow and draft.
Temperature Variations Inside Chamber:
- Food nearer firebox runs hotter.
- Upper grates are usually 15-30°C (30-50°F) warmer than lower grates.
- Position food thoughtfully to manage cooking times and bark formation.
In addition to the temperature dial on the pit itself, always use a temperature probe or instant-read thermometer to check the internal temperature of the food.
Note: Opening the cooking chamber door causes temperature dips; don’t overcompensate by changing vents - temperatures will recover.
Firebox Grilling: A Versatile Bonus
Some offset smokers come with firebox grills or plancha inserts, letting you sear or grill directly over the firebox fire after slow smoking. This is ideal for finishing or adding grilled textures without needing a separate grill.
Routine Maintenance for Longevity
Proper care extends the life of your smoker, ensuring you get years of cooking enjoyment and mouth-watering feasts. It also keeps the pit looking good and prevents damage that can cause rust or corrosion issues over time.
Rust Prevention:
- Many premium smoker pits are treated with linseed oil, which forms a durable, heat-resistant coating. This is used instead of paint which creates a sealed protective barrier.
- Regular paint can flake under heat. As it peels and flakes, it exposures the raw metal underneath. Painted pits need to be kept under a durable, fully waterproof cover in order to protect them from UK weather.
- Reapply linseed oil to scratched areas; accelerate curing with heat from a propane torch or regular use at >230°C (450°F). It’s recommended to reapply linseed oil to the external areas of the pit at least once a year to keep it in tip top condition.
Interior Care:
- Do not apply linseed oil inside. Instead, lightly coat internal surfaces with vegetable oil or tallow and “season” by running the pit hot (450-500°F) for a couple of hours.
Cleaning:
- Remove ash regularly to prevent moisture build-up and corrosion.
- Drain grease via any provided valves after each cook to reduce grease fire risk.
Safety:
- Linseed oil-soaked rags can spontaneously combust. Always soak them in water and store in metal containers before disposal.
