The brisket is coated in a rub and completely wrapped in bacon – 1 full pound of bacon- and slow-cooked in the oven. The smokey flavor of the bacon really penetrates into the meat and all that pork fat coating the beef brisket really adds to its flavor.
A super flavorful sauce that is both sweet and spicy is made from the bacon, which is finely chopped, cider vinegar, dark brown sugar, chicken broth, ketchup, and chipotle peppers. Once cooked, you can strain the sauce and discard the bacon, or I like to strain half of the sauce and then add it back to the saucepan. This way, there’s still some bacon, but it’s not an overwhelming amount.
Leftovers heat up well and this would be a good thing to cook in advance if you are having dinner guests. If you are just feeding your family, you can get multiple meals from this Oven-Barbecued Brisket. No kidding, I usually manage to get 3 meals out of it. Leftovers can be made into Brisket Grilled Cheese Sandwiches or Brisket Nachos.
Place oven rack in upper-middle position and heat oven to 275 degrees. Rub dry rub all over brisket and poke holes all over with a fork. Place half of bacon going crosswise in a broiler safe 9 by 13-inch pan (it’s best not to use glass). Put brisket fat side down on top of bacon. Lay the rest of the bacon crosswise on top of brisket, wrapping it down around the sides, and tucking any excess under. Cover pan with foil and place in oven for 4 hours.
Pour accumulated juices from brisket into large measuring cup or a bowl. Remove bacon from brisket and chop into pieces. Cook bacon in medium saucepan over medium heat for about 5 minutes, until fat has rendered. Add onion and cook until softened, 4-5 minutes. Take off heat and add vinegar and dark brown sugar. Return to heat and simmer until reduced to a syrupy consistency, about 5 minutes.
Skim fat from accumulated juices and add chicken broth to make a total of 3 cups. Add to mixture in saucepan and reduce until about 3 cups in volume, 8-10 minutes. Take off heat and add ketchup. Mix well and strain if desired. (I like to strain about half the solid pieces out and leave the rest). After straining, add chipotle peppers.
