How long to smoke brisket at 250
If you’re wondering how long you should be smoking a brisket at 250°F in ambient temperature, you have certainly come to the right place.
Smoking at 250°F is right in the middle between low and slow and hot and fast.
It could be a great compromise between the two, while also administering plenty of smoke to your brisket.
Not only that, but it can also be a great way to expedite your current cook as you smoke a brisket.

On average, you can expect about 1 1/2 pounds per hour of cook time assuming you are cooking a brisket consistently at 250°F.
Make sure to try and keep this temperature range consistent, and that way you can always have a good estimation in terms of how long it should take going forward.
Once the brisket is done, just pull it off once the internal temperature is at 200°F, and once it probes tender of course.
Final thoughts
If you’re smoking your brisket at about 250°F, then you should know that it takes roughly 1 1/2 pounds per hour to fully cook through.
