This burger stacks sliced smoked brisket on a toasted brioche bun with melted cheddar, barbecue sauce, and quick-pickled red onions. The pickled onions take about 20 minutes of hands-off time, and if you buy pre-smoked brisket from a grocery store or barbecue joint, the whole thing comes together fast. It is a genuinely satisfying weeknight burger that does not require a smoker or a free Saturday.
Shopping notes
- Pre-smoked brisket: Many grocery stores with a deli counter or in-store BBQ program sell sliced smoked brisket by the pound. Call ahead — it sells out. Leftover brisket from a restaurant order works just as well.
- Brioche or potato buns: Either works. Look for buns that feel slightly dense rather than airy; they hold up under the sauce without turning to mush.
- Red wine vs. apple cider vinegar: Both work for the quick pickle. Apple cider vinegar gives a slightly milder tang; red wine vinegar gives a sharper bite and keeps the onions a brighter pink.
- Barbecue sauce: Use whatever you already have open. A smoky, less-sweet sauce (think Texas or Carolina style) keeps the brisket flavor in front rather than burying it under sugar.
The technique that matters
The quick pickle is the one step worth doing right. Slice the red onions as thin as you can — a mandoline is ideal, but a sharp knife and patience work fine. Thicker slices stay harsh and crunchy in the center even after 20 minutes in the brine; thin slices soften and absorb the vinegar all the way through. Skip reusing the brine for a second batch of onions — it dilutes too much and the second batch comes out flat. Make a fresh brine if you need more. Toasting the buns is the other non-negotiable: a dry skillet over medium heat for about 90 seconds per bun creates a barrier that keeps the barbecue sauce from soaking straight through to your hands.
Troubleshooting
- Brisket turns out dry when reheated: Do not microwave sliced brisket uncovered. Add a tablespoon of beef broth or water to the container, cover it, and microwave in 30-second bursts, or warm the slices in a covered skillet over low heat.
- Pickled onions taste too sharp: Add a pinch more sugar to the brine and let them sit another 10 minutes. A small amount of sugar rounds out the vinegar without making the onions sweet.
- Cheese will not melt onto cold brisket slices: Lay the cheese directly on the brisket while it is still warm from reheating, then tent a piece of foil over the plate for 60 seconds. The trapped steam does the job.
- Bun gets soggy before you finish building: Spread barbecue sauce on the bun last, right before you stack the brisket, not while the bun is still hot from toasting.
- Onions slide out of the burger: Place the pickled onions under the brisket rather than on top. The weight of the meat holds them in place.
Leftovers and meal prep
Sliced smoked brisket keeps in an airtight container in the fridge for up to 4 days. The pickled onions actually improve after 24 hours and stay good for up to 2 weeks refrigerated in their brine — making a full jar ahead of time is worth it. Assembled burgers do not store well, so keep the components separate. For freezing, wrap brisket slices tightly in plastic wrap and then foil; they hold for up to 3 months and reheat well using the covered skillet method above. Frozen brisket is best thawed overnight in the fridge rather than defrosted in the microwave, which tends to dry out the edges.
Smoked Brisket and Pickled Red Onion Burger
Ingredients
For the Brisket
- 1.5 kg beef brisket Ideally a well-marbled cut
- 16 g barbecue rub Your favorite store-bought or homemade rub
For the Pickled Red Onions
- 1 large red onion Thinly sliced
- 120 ml white vinegar Or apple cider vinegar
- 120 ml water
- 12.5 g granulated sugar Adjust sweetness to taste
- 5 g salt
For the Burger Assembly
- 4 pieces burger buns Preferably brioche or potato buns
- 60 ml barbecue sauce Use a high-quality brand for best flavor
- 4 slices cheddar cheese Or your preferred melting cheese
- 30 g fresh lettuce leaves Optional, for freshness and crunch
Instructions
- Smoke the Brisket: Rub the brisket thoroughly with your barbecue rub. Preheat your smoker to 107°C (225°F). Place the brisket in the smoker, fat cap up, and smoke for about 8 hours or until it reaches an internal temperature of 93°C (200°F). The brisket should be tender and juicy. Let it rest for 30 minutes before slicing.
- Prepare the Quick-Pickled Red Onions: In a small saucepan, bring the vinegar, water, sugar, and salt to a gentle simmer. Stir until the sugar and salt dissolve. Remove from heat and pour the mixture over the thinly sliced red onions in a heatproof bowl. Let them sit for at least 20 minutes, or until they turn a vibrant pink hue and soften slightly.
- Slice the Brisket: Once rested, slice the brisket against the grain into thin slices. Keep warm on a low heat or in a warming drawer if possible.
- Toast the Buns: Lightly toast the burger buns on a hot grill or skillet. This helps prevent them from getting soggy once sauced and layered with toppings.
- Assemble the Burgers: Spoon a little barbecue sauce onto the bottom half of each bun. Layer with a few warm brisket slices. Top with a slice of cheese (allowing it to melt slightly), a generous heap of pickled red onions, and lettuce leaves if desired. Spread extra barbecue sauce on the top bun before placing it over the filling.
- Serve and Enjoy: Serve the burgers hot off the grill or pan, with any remaining brisket slices on the side for an extra treat.
Notes
- If you don’t have a smoker, you can use pre-smoked brisket from a trusted barbecue restaurant or grocery store.
- For a quicker cook, use a smaller piece of brisket, though smoking time is crucial to achieving tender meat.
- Add sliced pickled jalapeños or spicy aioli for a hot kick.
- Present each burger on a wooden board or large platter to showcase the layers of smoked brisket and pickled onions. Pair with crispy fries, sweet potato wedges, or a fresh coleslaw.
- A cold, crisp lager or a tangy lemonade balances the richness of the brisket.
- Smoked brisket is iconic in American barbecue culture, particularly in the Southern states. The addition of quick-pickled onions adds brightness and modern flair while paying homage to the tangy accompaniments often found in barbecue feasts.
- You can prepare the pickled onions a day in advance for deeper flavor.
- If you have leftover brisket, reheat it gently to avoid drying it out. Try sous-vide reheating or low-temperature oven warming for best results.

Your questions, answered
Can I use ground brisket instead of sliced smoked brisket?
Yes, but the burger becomes a different recipe — a ground beef patty rather than a smoked meat sandwich. If you go that route, grind the brisket yourself or ask a butcher, and cook the patty to an internal temperature of 160°F (71°C) since it is ground beef.
How long do the pickled onions need to sit before they are ready?
Twenty minutes in the hot brine gives you onions that are tangy and slightly softened — good enough to use right away. Overnight in the fridge makes them noticeably better, so if you have time to make them the night before, do it.
What if I can’t find pre-smoked brisket near me?
Check barbecue restaurants that sell meat by the pound to go — most will slice it fresh for you. As a backup, a good smoked pulled pork or smoked beef chuck from a deli counter gives you a similar flavor profile and works with all the same toppings.
