This is a wagyu beef burger glazed with homemade teriyaki sauce, topped with shredded napa cabbage, pickled red onions, and Japanese mayo on a milk bun. Wagyu’s high fat content means the patty stays juicy even if you pull it a few seconds late, which makes it genuinely forgiving for a home cook. If you want a burger that feels special without a complicated technique list, this is a good one to have in your rotation.
Smart swaps
- Ground wagyu: If your butcher doesn’t carry it, ask for an 80/20 ground beef blend — the fat ratio is what matters most here. True wagyu is worth it if you can find it, but a good 80/20 Angus will still work well with this glaze.
- Mirin: If you can’t find mirin, use 1 tablespoon dry sherry plus half a teaspoon of sugar per tablespoon of mirin called for. Rice wine vinegar is not a substitute — it’s sour, not sweet.
- Japanese mayo (Kewpie): Most large grocery stores carry it now, but in a pinch whisk together regular mayo with a small splash of rice vinegar and a drop of sesame oil. It won’t be identical, but it’s close enough.
- Milk buns: A brioche bun is the most practical swap. Avoid standard sesame-seed burger buns — they’re too dry and fall apart under the glaze.
- Napa cabbage: Green cabbage works fine and holds its crunch a little longer, which is useful if you’re assembling burgers ahead of time.
Before you start
The one technique that actually matters here is controlling the teriyaki glaze during the final cook. The glaze has a lot of sugar, and sugar burns fast over high heat. Brush it on only in the last 60 to 90 seconds of cooking — not before — and keep the heat at medium-high rather than screaming hot. If you apply it too early, you get a bitter, blackened crust instead of a sticky, caramelized one. The second thing worth knowing: handle the wagyu patties as little as possible when forming them. The fat starts to melt from the warmth of your hands, and overworked patties tighten up and lose that loose, tender texture that makes wagyu worth the price.
Common problems and fixes
- Patty shrinks into a thick puck: This usually means the patties were packed too tightly. Form them loosely and press a shallow dimple in the center before cooking — this helps them stay flat as they cook.
- Glaze runs off the patty instead of sticking: The patty surface is probably too wet. Pat the patties dry with a paper towel before they go on the heat, and make sure the pan or grill is properly preheated before you add the meat.
- Pickled onions are too sharp: Let them sit in the brine for at least 30 minutes, but if they still taste harsh after that, add a pinch more sugar to the brine. Quick-pickled onions mellow significantly between the 30-minute and 2-hour marks.
- Milk bun gets soggy fast: Toast the cut sides in a dry pan until they’re golden — not just warm. A properly toasted bun creates a barrier that holds up against the glaze and mayo for much longer.
- Burger tastes flat despite the glaze: Season the patties with salt on both sides right before they hit the pan, not in advance. Salting too early draws out moisture and can make the surface steam rather than sear.
Make-ahead notes
The teriyaki glaze keeps in a sealed jar in the fridge for up to two weeks — make a double batch and you’re set for several meals. Formed raw patties can be stacked with parchment between them and refrigerated for up to two days, or frozen for up to three months; thaw overnight in the fridge before cooking. Pickled red onions are actually better after 24 hours and will keep refrigerated for up to a week, so make them the night before. Cooked patties reheat well in a covered skillet over low heat with a splash of water — about three to four minutes — which keeps them from drying out. Skip the microwave if you can; it toughens the meat. Assemble toppings fresh each time since the napa cabbage wilts quickly once it hits a warm patty.
Japanese Teriyaki Wagyu Burger
Ingredients
For the Wagyu Burger Patties:
- 1.5 pounds Wagyu ground beef preferably 80/20 fat ratio for maximum juiciness
- 1 teaspoon kosher salt
- 0.5 teaspoon freshly ground black pepper
For the Teriyaki Glaze:
- 0.5 cup low sodium soy sauce
- 0.25 cup mirin
- 0.25 cup brown sugar light or dark, packed
- 1 tablespoon grated fresh ginger
- 1 tablespoon minced garlic
- 1 tablespoon cornstarch mixed with 2 tablespoons water for thickening
For the Burger Assembly:
- 4 pieces Japanese milk buns or brioche buns
- 1 cup shredded napa cabbage freshly shredded
- 0.5 cup Japanese mayo (e.g., Kewpie)
- 0.25 cup pickled red onions optional, for brightness
- 2 teaspoons toasted sesame seeds for garnish
Instructions
- Prepare the Teriyaki Glaze: In a small saucepan over medium heat, combine soy sauce, mirin, brown sugar, ginger, and garlic. Bring to a gentle simmer. Stir in the cornstarch and water slurry, continuing to whisk until the sauce thickens into a glossy glaze, about 5–7 minutes. Set aside to cool slightly.
- Make the Wagyu Burgers: In a mixing bowl, gently combine the wagyu ground beef with salt and pepper. Do not overmix. Form four uniform patties, slightly wider than your buns to allow for shrinkage.
- Grill or Pan-Sear the Patties: Heat a cast iron skillet or grill over medium-high heat (about 375°F/190°C). Sear each patty for 3-4 minutes per side depending on thickness and desired doneness. During the final minute, brush the tops generously with the teriyaki glaze and allow it to caramelize slightly.
- Toast the Buns: Lightly butter the inside of each milk bun and toast them on a skillet or grill until golden brown and crisp, about 1 minute.
- Assemble the Burgers: On each toasted bun base, spread Japanese mayo, then layer shredded cabbage, the hot teriyaki-glazed burger patty, a spoonful of pickled onion, a sprinkle of sesame seeds, and finish with the top bun.
Notes
- For a spicy kick, add a drizzle of sriracha mayo or a slice of shiso leaf for herbal brightness.
- If you don’t have wagyu, use high-quality ground beef with at least 20% fat content.
- Make your teriyaki sauce up to 3 days in advance and refrigerate for faster assembly.

Frequently asked questions
What internal temperature should I cook the wagyu patty to?
Ground wagyu should reach 160°F (71°C) internal temperature, the same as any ground beef. Ground beef — including wagyu — is not safe to serve rare or medium-rare because the grinding process can distribute surface bacteria throughout the patty; whole-muscle wagyu steaks are a different matter, but not ground.
Can I use store-bought teriyaki sauce instead of making the glaze from scratch?
Yes, store-bought works, but choose a thicker, glaze-style teriyaki rather than a thin marinade — the thin ones don’t caramelize well and tend to make the patty surface wet. If your store-bought sauce is runny, simmer it in a small pan for a few minutes to reduce it before using.
Can I cook these on a stovetop instead of a grill?
A cast-iron skillet works great and actually gives you more control over the glaze at the end. Get the pan hot before adding the patties, and use the same timing as you would on a grill — the glaze goes on only in the final 60 to 90 seconds.
Where do I find ground wagyu beef?
Specialty butcher shops and some warehouse stores like Costco carry ground wagyu fairly regularly. It’s also widely available online from several beef suppliers who ship frozen — ordering in bulk and freezing individual patties is a cost-effective approach.
Can I freeze the cooked patties with the glaze already on them?
Yes — glazed cooked patties freeze well for up to two months wrapped tightly in plastic wrap and then foil. Reheat them covered in a skillet over low heat; the glaze will re-caramelize slightly as they warm up, which actually improves the texture compared to reheating plain cooked patties.
