Get Started


[MUSIC PLAYING] - Over the years, cooking barbecue really has only meant cooking over live fire. It could be a pit in the ground. It could be in a green egg. It could be on a grill. But for me, I really like offsets. I think most people feel comfortable cooking on whatever they learned on. And for me, it was an offset cooker. It was a cheapo $99 offset cooker that I got at the sporting goods store. It wasn't very good. In fact, it was kind of terrible. It was really thin, but somehow I managed to make at least two good briskets on that thing. And it also helped me figure out what I wanted to change on that to build my own cooker that was a lot better-- more the way that I wanted it to. And that is how we ended up with these. [MUSIC PLAYING] And this is just a classic offset cooker, much like I started on, but it's a pretty souped up version of the first cheapie. Really, back in the day, I ended up building cookers because I just wasn't happy with anything that was on the market. You go to the store, you look to buy something, and maybe the fire box is really, really short, which I don't like. I'd like to be able to build the fire further back and then adjust where that fire goes. You know, maybe they have multiple shelves. Well, I don't really want that, because I don't want the piece of meat on top, dripping on the one that's below. So that doesn't work for me. And then if you go to buy one, and it's got a thermometer on the lid, well, I don't want it there. Because of all the heat's going to go right there, and it's going to read really, really hot. And it doesn't make any sense if the meat's down here. If the thermometer is on the door, every time you slam the door it's going to mess with the thermometer. Also with the smokestack, I don't want one that comes out here. I don't want one that comes out here. I want it to pull the heat across the grates a little bit. So I'd say between those four things-- fire box, single grate, thermometer placement, and make sure the smoke stack's coming up in the right place. It should be kind of in the range. I also think the thickness of the metal has a lot to do with it. You go to the store, and you buy just a cheapie kind of thing. It's usually made out of real thin metal. So if it rains or it's cold outside, you're building this huge fire. And by the time it gets down here, like, the end of the cooker is just ice cold. So it's nice-- like, this is quarter inch thick. This is quarter inch thick. It's not going to rest out too quickly. It's going to last a long time. If you take care of it, it's going to last forever, really. Then the fire box, likely, once you get a coal bed and you start to build it up, you kind of have enough heat retention in there to keep it warm so you're not always just, like, every three minutes throwing a piece of wood in there. You don't really have to struggle quite so hard. I think it's safe to say that the cheaper the cooker gets with thin metal, ...

Students give MasterClass an average rating of 4.7 out of 5 stars.

Great class. Very interesting and fun to watch. The instructor full of experience.

I enjoyed the class. I think I would have enjoyed a sausage making and smoking added, as I know that it is also a very big part of Central Texas Barbecue.

I always love Aaron's video's.Purchased because I've watched the PBS video's many times. He is one of the most influential guys to me in my venture

Very detailed class. I have been cooking and smoking BBQ most of my life and the bottom line is that I was doing it all wrong.

It'd be interesting to see how he maintains his smokers - preventing/cleaning rust etc. Enjoyed the classes !


When making an offset smoker using old tanks is there a ratio that needs to be followed for length vs diameter for it to function correctly?


What is the best advice for what to use in order to clean your offset smoker and grates?

This was really helpful. I would like to know more about that apparatus inside the cook chamber that is against the right wall (as you open the cook chamber door) that he sits the water container on. He eluded to it directing the heat and airflow from the fire box down, but is unclear how it is situated. Would love to see a cross section.

I’m building my own smoker. From the class Aaron only mention about controlling temperature from the firebox door. But I have seen many offset smoker with the chimney adjustment. Is the adjustment used to control the temperature or just the cover from rain?

Hello guys. So I am trying to build my own offset smoker, I live in south America so buying one is actually impossible here, and i have a question, would it make a big difference if the cooker is octagonal and not circular? I do not know if the geometrical shape could mess up the wind circulation.

Hi There, I enjoyed the course! However I think it misses a part where Aaron is talking about mulitple cooks in one smoker. When you see the footage of his store, you see those huge smokers that have 24 briskets on it, but how does a smaler cooker handle mulitple briskets? Do you rotate them to equalize the head spread or do you work with different temperatures? Advice on this would be great, since I think about building my own smoker with a capacity of 3-5 briskets? Any hint on where to go for directions? Thanks in advance, Robert


I have a Oklahoma Joe's longhorn offset smoker. Its built pretty well, i did a few modifications to it but the one i cant figure out is like in the video the metal box in the cook chamber that the water is sitting on top of. Can anyone help?

I use a pellet smoker which works pretty well for me but after watching all of Aaron's videos that I can find I want to start using an offset smoker. I can buy one from the store but I really want to get a decent one that I can use for a long time. Any recommendations? I really like what I see with Aaron's but not sure of the cost, I was also looking at Oklahoma Joes but it seems a little less quality than what I would like.

I got tired of waiting for Aaron to start selling his signature smokers (and the ones being built by his business partners are crazy expensive). I found a local pit builder and he's building one for me that's pretty close to what Aaron is cooking on in the videos. The only thing I can't figure out is what the piece of metal is that's inside the cook chamber, right next to the firebox (the container of water is sitting on it). Can anyone help me out? Thanks.
