Toss together the paprika, brown sugar, chili powder, garlic and onion powders, chipotle, pepper, salt, thyme, and cayenne. Spoon out one tablespoon for the sauce later.

Fire up the broiler. Place brisket on a foil-lined pan, brush on lots of barbecue sauce. Broil for 5-10 minutes so it gets a dark, sticky crust.

Warm up the leftover barbecue sauce either on the stove or in the microwave.

If you're planning ahead, let brisket cool in its juices in the cooker insert. Stick it in the fridge, skim off the fat, and then reheat on low for 1-2 hours. Finish with broiling and slice to serve.
