This burger mixes ground beef with bulgogi sauce right into the patty, then glazes it again on the grill — so the Korean BBQ flavor goes all the way through, not just on top. The toppings are kimchi, cucumber, and red onion on a sesame-oiled brioche bun. It comes together in 45 minutes and uses one bowl and one pan or grill.
Before you start
The two things that actually affect the outcome here are how you mix the meat and how you manage the glaze. Mix the beef and bulgogi sauce just until combined — overworking ground beef tightens the proteins and gives you a dense, rubbery patty instead of a juicy one. For the glaze, wait until the patty has been on the heat for a couple of minutes before brushing; if you apply bulgogi sauce to cold meat on a hot surface too early, the sugars in the sauce scorch before the beef has a chance to cook through. Brush it on in the last 2 minutes of each side so it caramelizes without burning. Pull the patties at an internal temperature of 160°F (71°C) — that’s the safe target for ground beef, and a quick-read thermometer is the only reliable way to hit it.
Common problems and fixes
- Patties puff up in the middle: Press a shallow thumbprint into the center of each raw patty before it hits the heat. Ground beef contracts as it cooks and the center rises; the indent compensates so you get a flat patty that sits properly on the bun.
- Sauce burns before the beef is done: Lower the heat slightly and move the patty to a cooler part of the grill or pan. Bulgogi sauce has enough sugar to blacken fast — medium-high is a ceiling, not a floor.
- Kimchi makes the bun soggy: Drain the kimchi briefly on a paper towel before assembling. It only takes 30 seconds and keeps the bun from going soft by the time you take a second bite.
- Patties fall apart on the grill: Make sure the grill grates or pan are fully preheated and lightly oiled before the patties go on. Cold or dry surfaces cause sticking, and sticking causes crumbling when you try to flip.
- Bun tastes greasy from the sesame oil: Use a very light brush — just enough to coat the surface. Skip the egg in the mix — it makes the patty mushy — and keep the sesame oil to a thin, even layer on the bun or it overwhelms everything else.
Make-ahead notes
You can shape the raw patties up to 24 hours ahead — stack them with a small square of parchment between each one, cover tightly, and refrigerate. They actually hold together better when cold. Cooked patties keep in an airtight container in the fridge for up to 3 days; reheat them in a covered skillet over medium-low with a splash of water to prevent drying out, about 3–4 minutes per side, and verify they hit 160°F (71°C) again before serving. For freezing, freeze raw shaped patties on a baking sheet first, then transfer to a zip bag — they’ll keep for up to 2 months. Thaw overnight in the fridge before cooking. Kimchi and sliced cucumber are best prepped fresh the day you’re eating; both go limp and watery if cut and stored.
Korean BBQ Beef Burger
Ingredients
Burger Ingredients
- 500 grams ground beef preferably 80% lean for juiciness
- 4 tablespoons bulgogi sauce store-bought or homemade
- 4 medium brioche buns lightly toasted
- 1 medium cucumber sliced thinly
- 1 cup kimchi chopped
- 2 teaspoons toasted sesame seeds for garnish
- 1 tablespoon sesame oil for brushing the buns
- 1 medium red onion sliced into rings
- 1 cup lettuce any crisp variety, leaves separated
Instructions
- In a mixing bowl, combine the ground beef and 2 tablespoons of bulgogi sauce. Mix gently to avoid overworking the meat. Shape into four equal patties.
- Preheat a grill or skillet over medium-high heat. Grill the patties for approximately 4 – 5 minutes on each side, basting with the remaining bulgogi sauce, until they are cooked to your desired doneness.
- Whilst the patties are cooking, lightly brush the inside of the brioche buns with sesame oil and toast them until golden brown.
- Assemble the burgers by placing a lettuce leaf on the base of each bun. Follow with the beef patty, then top with sliced cucumber, kimchi, red onion rings, and a sprinkle of toasted sesame seeds.
- Cap with the top bun and serve immediately for the best flavor and texture.

FAQ
Can I use store-bought bulgogi sauce or do I need to make it from scratch?
Store-bought works fine here. The recipe calls for only 4 tablespoons total, so a quality bottled sauce — look for one with soy sauce, pear or apple, and sesame listed near the top of the ingredients — does the job without any extra prep or dishes.
What if I don’t have a grill — can I cook these in a skillet?
Yes, a cast-iron or heavy stainless skillet over medium-high heat works just as well. You won’t get grill marks, but the caramelization from the bulgogi glaze in a hot pan is actually very good — possibly better than a gas grill for getting a proper sear.
My family doesn’t like spicy food — is the kimchi going to be a problem?
It depends on the kimchi. Most store-bought kimchi has moderate heat, but you can rinse it briefly under cold water to tone it down without losing the tangy fermented flavor. Alternatively, swap it for quick-pickled cabbage if you want zero heat.
Can I use leaner ground beef, like 90/10, to make this lighter?
You can, but the patties will be noticeably drier since the bulgogi sauce alone doesn’t add enough fat to compensate. If you go leaner, pull the patties right at 160°F and don’t let them sit — every extra minute on heat makes the difference between juicy and dry with lean beef.
