It’s not just what you cook in your smoker that matters. It’s also how you cook it.

Here are the basics of an offset smoker for anyone who isn’t very familiar with them.

Offset smokers are a type of smoker that have the cooking chamber separated from the firebox.

The heat from the fire is drawn by convection into the cooking chamber, generating smoke and cooking food.

This design gives these smokers their distinctive look, so they are one of the most recognizable styles of smokers on the market today.

The benefit to having a separate firebox is that it helps regulate temperature more easily.

so if you need to change it up you don’t have to start over by opening up the smoker and adding more fuel to get it going again.

How Do Offset Smokers Work?

The way an offset smoker works is that the heat and smoke go into the cooking chamber, and then out of the vents in the side or top.

The food is placed inside the cooking chamber which is then cooked gradually by smoke.

The smoke then travels down a pipe to another pan, called a smoke stack. The smoke stack is usually made of steel or aluminum, but can also be ceramic or clay.

That pan is where you put your fuel. It holds the fuel (usually charcoal) and creates more heat that goes back into the smoker to keep it going.

Design of an offset smoker

Usually the design of an offset smoker includes following parts.

A steel bowl

Offsets are usually made with a steel bowl (also called a firepot) that is surrounded by a water pan.

The firebox is designed to hold the fuel, which is usually charcoal, but can also be wood chunks or wood pellets.

The fuel heats up and creates smoke that travels through the water pan and into the cooking chamber.

Cooking chamber

The cooking chamber is where your food cooks. It’s made of steel and has a grate over the top, which holds your food while it cooks.

There are vents on the side or top of the chamber that allow you to regulate how much heat gets into your food, so you can control how fast it cooks and how well done it gets without burning it.

The firebox

The firebox is designed to hold the fuel for your smoker and it’s usually where you put lighter fluid or other accelerants to help get things going quickly and easily.

The firebox can vary in size depending on the amount of charcoal needed to complete the smoking process .

The firebox door is the  that allows you to add fuel to the firebox of your smoker. Some smokers have a lever or latch that opens it, and some have a hinge that you pull up to open it.

Water pan

A water pan is used in almost all smokers because it helps regulate temperature by absorbing some of the heat from your  fire.

the water pan is usually required when smoking, but when you are using your smoker for grilling then you can avoid using them in smoker.

A water pan also helps to keep the meat moist by catching drippings and adding moisture back into the air.

Drip pan

A drip pan is a small pan that you place directly under your food in the smoker. It catches any drippings that fall off of it, so they don’t burn up and smoke your meat. This makes clean-up easier!

Temperature gauge

A temperature gauge is a device that measures how hot your smoker is, so you can regulate how much heat gets into your food and how fast it cooks.

Air vents

The vents on either side of an offset smoker allow you to control how much heat gets into the cooking chamber, which regulates the temperature inside of it.

The vents on top usually have some kind of tool to adjust them for  you.

Smoker cover

There’s usually a cover on top of the cooking chamber of an offset smoker, so you can place food in there without having to worry about rain or other things getting into your smoker.

smoke stack

A smoke stack is what allows smoke to get out of your smoker and into the air around it. It’s usually connected directly to your firebox and often has holes in it for extra airflow.

even you can build your own offset smoker with custom features if you like to. but it will require a bit effort before working in a single piece.

Step by step guide to using an offset smoker

When you think of BBQ, you usually think of a smoker. Smoking meat is a timeless tradition that has been around since the days of our ancestors.

Using today’s modern technologies, we can create delicious BBQ without all the hassle and wasted time.

One such example is an offset smoker. An offset smoker balances heat and smoke in a way that creates a perfect environment for smoking any type of meat.

This guide will teach you how to use an offset smoker in step by step instructions so you can become a BBQ master!

Step 1

The first step is to purchase an offset smoker. The price will vary depending on the brand and quality of the product, but a good quality offset smoker should cost you around $200-$400.

Step 2

Now that you have your offset smoker, it is time to assemble it. This might seem like a daunting task, but it really isn’t too hard to do.

Most smokers come with easy to read instructions that will guide you through the process of assembling your smoker.

If you are having trouble assembling your smoker, or if you are unsure if it is assembled properly, contact customer service for help.

Step 3

The next step in using an offset smoker is to prepare your meat for smoking. You should choose meat that has been previously frozen so there is no bacteria present when you smoke the meat.

Also, make sure that there are no bones in the meat as this can cause clogging and make for an unpleasant smoking experience; bones are best used for soups or stews.

Step 4

Season your meat with a dry rub. You can make your own rub, or you can buy one at the store.

The choice is up to you, but make sure that you season the meat thoroughly so that it has a nice flavor throughout when it is finished smoking.

Step 5

Before you start smoking your meat, fill your smoker box with charcoal briquettes and light them on fire.

Let the coals burn for about 20 minutes to get them hot enough to smoke the meat; this will also allow any chemicals from the charcoal to burn off so they do not affect the taste of your meat.

Step 6

Place your seasoned meat onto a cooking rack and place it into the smoker box on top of the lit coals.

Close up the smoker and let it smoke for about 3-4 hours per pound of meat (about 1 hour per pound if using brisket).

Make sure that you keep an eye on your smoker so that you do not let the temperature get too high or too low.

This can ruin your meat, so keep an eye on it to make sure it does not go over 250 degrees Fahrenheit and does not go below 200 degrees Fahrenheit.

Step 7

After smoking your meat, remove it from the smoker, wrap it in aluminum foil, and place it in a cooler to rest for about 2 hours.

This will allow the juices to redistribute throughout the meat, making for a more tender end product.

Tips For Cooking With an Offset Smoker

An offset smoker is a powerful tool in the kitchen. It can turn inexpensive cuts of meat into succulent delicacies with a depth of flavor unmatched by most modern cooking methods.

However, if you’ve never used an offset smoker before, this process can seem daunting and complicated.

  • The most important tip is to make sure your smoker is up to temperature before you put meat on the fire. If you put a green brisket on a cold smoker, there will be some unpleasant texture left from not cooking it long on low heat first. 
  • Add wood chunks when smoking food that takes longer than 4 hours. Do this once or twice over the course of those hours for added flavor to the meat. 
  • Find some good recipes for your specific offset smoker. If you’re buying an offset smoker, the best and easiest way to cook great meals is using recipes made specifically for it
  • filling it with hardwood chunks and adjusting the temperature as necessary based on how dense or fast-burning that kind of wood is. 
  • Avoid leaning thin food directly above intense flames at high temperatures and avoid slow smoked foods directly above high heat flames that might burn your food through excessive exposure to radiant heat (such as searing, grilling, etc.) 
  • Look into buying an electric thermometer if you don’t have a separate one. 
  • If your offset smoker is missing thermometers, throwing meat in the cold section to try to cook things to a certain temperature can be dangerous because you may not have control over the internal temperatures and the fire can burn and scar your food while it waits.
  • Even if you do have an additional thermometer it would be helpful to get one that is electric or has remote display so that you don’t have to stick your hand into a hot part of the meat during food preparation.

Offset Smoker Fuels

Offset smoker fuels are also called “firewood” or “charcoal.” They are often used as the primary fuel within a smoker.

Hardwoods such as oak and hickory provide a long-lasting, steady flame because of their density and high moisture content.

Softwoods such as pine and fir tend to produce more smoke than hardwoods due to their lower density and higher moisture content.

The type of wood you use will play a huge role in flavor and aroma that you get from your meat.

Hardwoods will typically cost around $8-$12 per bag, while softwoods may cost you anywhere from $5-$6 per bag.

It’s important to keep in mind that the type of wood you use will not only affect how your meats turn out, but it can also determine whether or not you need to add additional flavors like apple juice, molasses, or sugar.

How big should be Offset smoker firebox?

When it comes to smoking meat, there are many different variables that can affect how it turns out. One of these variables is the size of the firebox on the smoker.

This section will discuss what size your firebox should be based on the number of racks you have in your smoker.

  • If you have one rack, your firebox should be about five inches wide and at least six inches deep.
  •  If you have two racks, your firebox should be about six inches wide and ten inches deep. You want to leave enough room for the smoke to circulate around the meat without getting too close to it.
  • If you have three racks, your firebox should be about eight inches wide and ten inches deep. If you have four racks, your firebox should be about ten inches wide and twelve inches deep.
  • If you have five racks, your firebox should be about twelve inches wide and twelve inches deep.
  •  If you have six or more racks, your firebox should be at least 14 inches wide and 14 inches deep.

You can also add additional space to the sides of the firebox if need be. A good rule of thumb is to make sure that there is at least one inch between the edge of the rack and the side of the smoker.

This will help prevent flare ups which can ruin your meat by burning off all of its  fat and leaving a bitter taste.

If you have a large smoker, you may want to consider installing a fan to help circulate the smoke around your meat.

This can be done by drilling holes into the back of the firebox. If you have an electric smoker, you can use a vent fan, or even just turn it on its side and prop it up with something that will keep it running constantly.

You can also try installing a thermometer in your smoker so that you can monitor the temperature more easily.

You will want your firebox to be on one side of the smoker, and your meat racks on the other side of the smoker so that there is space for heat and smoke to circulate around smoker easily.

How to use an offset smoker with wood chips?

If you have a smoker that uses wood chips, you need to use a smoker box. There are actually two types of smoker boxes.

The wood chips can be placed directly on the coals, or they can be placed in a smoker box. If you’re using a smoker box, place it directly on the coals.

It’s a good idea to leave the cover open so that the smoke can flow freely from the box.

When you’re smoking fish, you’ll want to keep the temperature between 200 and 225 degrees. You’ll need to add more wood chips every 45 minutes or so.

If you’re using a smoker box, you should replace the wood chips every hour or so. The reason is that they will burn quickly, and the box will get too hot.

You can use any type of wood chips for smoking fish, but some of the best woods to use are hickory, oak, mesquite and apple.

Hickory is probably the most popular choice. If you can’t get any wood chips, use charcoal briquettes instead. They work pretty well for smoking fish too!


In this blog post, you have learned the basics of how an offset smoker works. As you can see, there is not a lot to it.

The smoke comes in through the firebox, and the meat sits on the grill. The smoke and heat cook the meat, and then you can eat it.

It’s pretty simple, but that doesn’t mean there aren’t a lot of other things you can learn about an offset smoker.

For example, you might want to learn about how to season your smoker for the first time, or how to take care of it after you buy it. Overall, we hope this post has been helpful, so use this information to make your smoking experience as enjoyable as possible!
