    Brisket Flat On The Bronco - Documenting The Cook

    There was recently a few questions concerning the cook time of a brisket flat, along with some questions about lighting the coals on a Bronco and vent settings. There’s been several people recently buying a Bronco and I thought I’d share a few tips and things that have worked for me. After learning so much from everyone here the last few years, I thought I might return the favor for some of the newbies….or just someone new to cooking a brisket.

    I put the brisket flat on at 9 am, planning on a roughly 6-8 hour cook at 250* - 275*, followed by a minimum 2 hour rest in the cooler…..that’s my plan anyway, we’ll see. I’ll begin with everything I’ve done, starting with the prep and continuing with hourly updates until dinner time.

    PREPPING THE BRISKET:
    Yesterday I trimmed the brisket flat, which weighed a little over 4 lbs afterwards, 4.3 lbs to be exact. It was a little less than 2” thick on the big end and about 1” thick on the other. I then dry brined both sides with coarse sea salt and placed it on a rack in my garage fridge. Total time dry brining was 16 hours. Before placing it on the smoker I sprinkled both sides with coarse pepper and granulated garlic powder.

    Trimmed and ready for the dry brine……

    ​​​​Lighting the Bronco
    As with a lot of folks here, my favorite briquettes for low and slow is B & B. After filling the charcoal basket with briquettes, I placed a tumbleweed on one side, underneath a few coals. I placed 3 hickory chunks in the coals. I always start my coals 1 hour before I want to place the meat on…..allowing time for 3 or 4 coals to light and for the Bronco to come up to temp, which today was 250*. It took exactly that much time today, I started the coals at 8 am and put the brisket on at 9 am.

    IT of the brisket was 29.5 in the thickest part. Placed the brisket on when ambient temp reached 250*

    After 1 hour in the smoker, [10 am] IT of the brisket went to 99*. After a few minor vent adjustments the Bronco remained stable at around 245* to 252*

    I’ll be back each hour and report on the temps with pics of the brisket as it cooks.

    FORGOT TO MENTION THIS BUT……when first lighting your coals, leave the vents and lid open. Once you’ve got 3 or 4 coals burning good, close the lid, both vents still open, and leave it like this, until you reach your target temp and place the meat on. Then partially close the vents as needed.

    During my low and slow cooks on the Bronco, using B & B charcoal, this is approximately where my vent settings remain for the duration of the cook…..your mileage may vary. This keeps me around 240* - 255*.

      One problem I see, your first beer pic is a little late😃. Kidding of course. I had to pick on something. I'm just jealous you have a brisket today I don't.

    3 hours into the cook, brisket IT has reached 159*. Bark is just beginning to form.

      Maybe hourly updates are just too much excitement for everyone. 🙄 I don’t want anyone hyperventilating over this, maybe just every few hours or so from here on….

    Henrik bought some kettles and and started holding classes a few years ago. Have you thought about opening up the Panhead John school of Oklahoma Joe Bronco BBQ?

      As my wife says "it's always better when you don't drink while your cooking". Long weekend cooks are the bane of my existence.

        I forgot to mention this but, this is the 2nd half of the brisket ecowper gave me last December for our Secret Santa. It’s a Snake River Farms Prime brisket! thanks again Eric!

      5 1/2 hours in…..[it’s 2:30] It’s been in a stall at 175* IT for a couple of hours. It’s looking and smelling good though! I decide to foil boat it and bumped up the cooker temps to 275*. Hoping it’ll be done at 5:00 for a 2 hour hold before dinner.

        Bumping up the temps [from 250* to 275*] and the foil boat have definitely helped to get it out of the stall. The IT has gone up 11* in 45 minutes. It’s now at 186*.

        I take it you mean stalling at IT 175, not 275... Looks really good! I can see the juices pooling on the surface, that's Stallsville for sure. Good time to boat that puppy!

        I’ve got the diffuser plate over the coals, I’d have to remove it and the brisket to see the coals. It’ll be time to remove the brisket for the hold in the next 30-45 minutes. I’ll take a pic and let you know how it looks though, not a problem. IT is at 198* right now.

        Panhead John might want to probe that puppy right now. 198F IT might be done on an SRF Prime.

      Holy moly! I just took the brisket off the smoker. Tender as hell, and when I picked it up it was all jiggly and stuff! Looked kinda like this…

        That's it. Don't need to go to the end of the post (but I will). Jiggly is key word. I know exactly what you mean. The brisket is done. Good job man!! I have only had a couple of jiggly briskets and that's why I don't smoke briskets often. Kudos!

      As fate would have it, I ordered a USDA Prime whole brisket just this morning as part of my Wild Fork order - starting to restock the chestie now that the weather has moved into autumn. Hadn't seen this yet though...

        bmillin This is why I like B & B charcoal so much. These pics were after I took the brisket off after smoking for 7 1/2 hours. This is what was left after 8 hours of burning. The coals that are ashed over are still solid looking. I could have probably gotten another 4-5 hours cooking out of em…..easily.

          Great write up on your Bronco brisket flat cook. B&B and the Bronco are great combo for low and slow.

            Ok folks the results are in!

            I took the brisket off the smoker after IT reached 200*. Cook time was 7 1/2 hours. 9am to 4:30pm. Then it was wrapped and into a cooler for a 2 hour rest. Here’s the brisket after the hold. A little trick I learned from fzxdoc was to place a few toothpicks in the brisket ahead of time, and have them run parallel to where you want to slice, after the cook. It’s difficult to see which direction the grain runs after the cook. I pulled them out of the meat a little so you could see them. They were inserted mostly all the way in.

            Overall I give this brisket cook a solid A minus. As with most flats, it was just a tad dry and not quite as tender as I wanted. I think next time I won’t trim a flat quite as much as I did this one. But, I’m honestly nit picking here. The flavor was excellent with a great smoke flavor and a peppery bark. Definitely one of the best briskets I’ve cooked!

              TripleB I did wrap and hold the brisket in a cooler for 2 hours, from 5pm to 7. I made the cuts after the hold. I just noticed I didn’t mention anything about the cook time and the hold above. Fixed it, thanks!

              Panhead John - That's what I figured. My tip - when it was jiggly, the brisket was ready to serve. No need to hold for 2 hours. The hold is to help it get to that jiggly state. Briskets (and chicken thighs) are hard to smoke.....IMHO.

              TripleB Just between me and you, the brisket wasn’t actually all that jiggly. I just said that as an excuse to insert the Pam Anderson video…..😂
