How to Reheat BBQ Brisket?

Unfinished and left-over brisket on the table.

A close friend called me last Sunday asking me about what to do with his brisket BBQ leftovers from last night. Well, I told him he might as well reheat them. I also reminded him that he must reheat the brisket leftovers in the same way he had cooked them. Of course, he can’t just stuff his leftover brisket back onto his oven without prepping it. He needs to moisten the meat with reserved cooking juices and wrap it using double foil layers.

But brisket is such a deliciously flavorful piece of meat when cooked longer using low heat.

Just like my friend, you might as well reheat those leftovers, and you can read on through this post to learn the best way to reheat brisket BBQ.
