For the Brisket
2 tablespoons vegetable oil
1 (3-pound) brisket, patted dry
1 teaspoon kosher salt
½ teaspoon freshly ground black pepper
2 large onions, thinly sliced
¼ teaspoon Thai chili flakes
1 cup Dill Pickle BBQ Sauce
¼ cup water
Dill Pickle BBQ Sauce
½ cup ketchup
¼ cup dill pickle liquid
¼ brown sugar
2 tablespoon soy sauce
1 teaspoon yellow mustard
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon cumin
1 teaspoon smoked paprika
For the Pickle Rice
2 tablespoons olive oil
1½ tablespoons unsalted butter
2 tablespoons minced garlic
4 scallions, thinly sliced (greens and whites separated)
1 tablespoon finely minced jalapeño
4 cups cooked rice
2½ teaspoons fish sauce
¼ cup finely chopped cornichons or dill pickles
⅓ cup chopped cilantro
For the Brisket
Preheat the oven to 325°F. Heat the vegetable oil over medium-high heat in a 5-quart lidded braiser or Dutch oven. Season the brisket evenly with the salt and pepper. Sear until deeply browned, 4–5 minutes per side. Transfer to a plate and cover loosely to keep warm.
Cook the Onions
Reduce the heat to medium-low. Add the onions and Thai chili flakes to the pot and cook, stirring, until softened and translucent, 9–10 minutes, scraping up any browned bits from the bottom.
Build the Braising Liquid
Stir in the BBQ sauce and water until combined. Nestle the brisket into the sauce and spoon some of the onions and sauce over the top.
Braise the Brisket
Cover the pot with a piece of parchment paper, then a layer of heavy-duty foil, and secure with the lid. Transfer to the oven and braise until the brisket is fork-tender, about 3½ hours.
Rest and Slice
Remove from the oven, uncover, flip the brisket, and let cool in the sauce for at least 30 minutes. Skim off and discard excess fat. Remove the brisket, slice against the grain, then return it to the sauce. Warm gently over low heat if needed.
For the Pickle Rice
Heat the olive oil and butter in a large skillet over medium heat. Add the garlic, scallion whites, and jalapeño and cook, stirring, until golden and fragrant, about 3 minutes.
Warm the Rice
Add the rice and fish sauce and cook, stirring, until warmed through, about 2 minutes.
Finish the Rice
Stir in the scallion greens, chopped pickles, and cilantro until evenly combined.
Serve
Spoon the pickle rice onto plates and top with sliced brisket and plenty of sauce. Serve warm.
