Why This Guide Beats Bon Appétit, Serious Eats and Food52
Serious Eats covers smash burgers but never applies the technique to kimchi. Bon Appétit’s kimchi burger recipe uses a thick patty that overwhelms the fermented toppings. Food52 doesn’t address bun selection at all — the single most structural decision in building a kimchi burger. Here is what we do that they don’t.
Difficulty Level
The smash technique requires confidence and speed — you have a 10-second window after placing the beef ball to smash it flat before the crust starts setting. Everything else is simple assembly. If you can move fast with a spatula, this recipe is yours.
Which Kimchi to Use in a Kimchi Burger
Kimchi age matters more in a burger than in almost any other fusion recipe. The beef and bun are rich, fatty and sweet — you need a kimchi with enough sour-umami complexity to cut through. Young kimchi does not have it. Ripe kimchi does.
Tastes like spiced cabbage. No lactic acid development means no sour contrast against the beef fat. The burger will taste one-dimensional and sweet-heavy.
Mild tang beginning. Works if ripe kimchi is unavailable. The burger will be good but lack the sharp sour contrast that makes a kimchi burger genuinely extraordinary.
Peak sour-umami complexity. The acidity cuts directly through beef fat and gochujang mayo richness. Creates the acid-fat balance that defines a great kimchi burger.
Very sour and pungent. Can overpower the beef. If using over-fermented kimchi, squeeze out most of the liquid and taste before adding — use sparingly.
Kimchi Burger Ingredients
Ingredient Substitution Guide
Every substitution below was tested. Impact ratings are honest — if something compromises the burger, we say so.
| Original Ingredient | Best Substitute ⭐⭐⭐ | Acceptable Substitute ⭐⭐ | Flavour Impact |
|---|---|---|---|
| 80/20 beef mince | 85/15 + 1 tbsp grated cold butter | 90/10 mince (drier result) | High — fat creates the crust |
| Brioche bun | Potato bun (Martin’s brand) | Any soft white burger bun | Medium — brioche sweetness balances gochujang |
| Kewpie mayo | Hellmann’s + ½ tsp MSG + ½ tsp rice vinegar | Regular mayo (noticeably blander) | Medium — Kewpie has umami depth |
| American cheese | Mild cheddar slice | Provolone (less melt) | Low — American melts best |
| Gochujang (mayo) | Sriracha (2 parts) + white miso (1 part) | Sambal oelek + ¼ tsp sugar | Medium — loses fermented sweetness |
| Napa cabbage (slaw) | White cabbage, very finely sliced | Pre-shredded coleslaw mix | Low — texture slightly denser |
| Rice vinegar | Apple cider vinegar (½ the quantity) | White wine vinegar (½ quantity) | Low — slight sharpness difference |
How to Make a Kimchi Smash Burger — 7 Steps
Seven steps. The smash (step 4) is the make-or-break moment — everything else is prep and assembly. Read step 4 fully before you cook.
Take 300g of cold 80/20 beef mince straight from the refrigerator. Divide into two equal 150g portions. Using the lightest possible touch, roll each portion into a loose ball — do not compact, do not knead, do not press. The less you handle the mince, the more tender the final patty. Season the outside of each ball with salt and black pepper just before cooking, not before. Set on a plate and refrigerate until the griddle is at temperature.
In a small bowl, whisk together Kewpie mayo, gochujang, sesame oil and rice vinegar until fully combined and uniform in colour. The tested ratio is 3 tablespoons Kewpie to 1 tablespoon gochujang — this delivers a clear spicy kick without the gochujang dominating. Taste it: rich, spicy, slightly tangy and deeply savoury. If it tastes flat, add a tiny drop more sesame oil. Refrigerate until assembly — it improves as it sits.
Squeeze excess liquid from the chopped ripe kimchi — press firmly in your fist over the sink for 4–5 seconds. Combine squeezed kimchi with shredded napa cabbage, sesame oil, rice vinegar and sesame seeds. Toss well and set aside for 5 minutes. The slaw should taste sour, crunchy and slightly nutty from the sesame. Do not dress more than 20 minutes ahead — the cabbage softens and the slaw loses its textural contrast against the hot patty.
Heat a cast iron griddle or heavy skillet over the highest heat for 2 full minutes. The surface must be visibly smoking before anything goes on it. Add the smallest possible amount of neutral oil — just enough to lightly coat. Place one cold beef ball on the griddle. Immediately — within 3 seconds — place a heavy flat spatula on top and press down with your full weight for a solid 10 seconds. The patty should spread to approximately 12cm and be 6–7mm thin. Cook undisturbed for 90 seconds until the edges are visibly brown and lacy and the top surface shows moisture evaporating. Repeat with the second ball. Work one at a time.
Flip each patty once only — using a thin, sharp metal spatula, slide cleanly under the patty and flip in one confident motion. Immediately place one slice of American cheese on top of each patty. Cook for exactly 45 seconds on the second side — the cheese should be fully melted and cascading slightly over the patty edges. Remove from heat. The total cook time is under 3 minutes per patty. A smash burger should never be cooked to well-done — medium with a pink centre is the target.
Without cleaning the griddle, reduce heat to medium. Add the butter and let it melt and foam. Place the brioche buns cut-side down in the butter and beef fat mixture. Press gently and toast for 60–75 seconds until deep golden-brown. The combination of butter and beef fat that remains on the griddle flavours the bun in a way that plain toasting cannot replicate. Watch carefully — brioche burns faster than regular buns due to its sugar content.
Spread gochujang mayo generously on both toasted bun halves — top and bottom, right to the edges. Place the cheese-topped smash patty on the bottom bun. Pile the kimchi slaw generously on top of the patty. Scatter sliced spring onion. Cap with the top bun. Press down gently — the patty should be visible peeking out from the sides. Serve immediately. Cut in half only if serving as a shared dish — cutting releases steam and softens the crust.

Test Kitchen — 10 Batches Tested
10 batches across 4 burger builds, 4 bun types, 3 kimchi ages and 3 cheese options. Here are the variables that change the outcome most dramatically.
The ratio of patty thickness to topping volume is the single most important variable in a kimchi burger. A thick patty overwhelms fermented toppings — kimchi, gochujang and sesame become background notes rather than the point. A thin smash patty is proportionally matched to bold Korean toppings, allowing every layer to contribute equally to the final bite. Build for the toppings, not the beef.
- 300g 80/20 beef mince, divided into two 150g balls
- 150g ripe kimchi (3–6 weeks), roughly chopped and squeezed dry
- 2 brioche burger buns
- 2 slices American cheese (or mild cheddar)
- 1 tbsp butter + 1 tbsp neutral oil
- 3 tbsp Kewpie mayo + 1 tbsp gochujang + 1 tsp sesame oil + 1 tsp rice vinegar (mayo sauce)
- 80g napa cabbage, shredded
- 1 tsp sesame oil + 1 tsp rice vinegar + 1 tsp sesame seeds (slaw)
- 2 spring onions, thinly sliced
- Salt and black pepper to season patties
- Form beef into two 150g loose balls. Season exterior with salt and pepper. Keep refrigerated until needed.
- Whisk Kewpie mayo, gochujang, sesame oil and rice vinegar into gochujang mayo. Refrigerate.
- Squeeze kimchi dry, combine with shredded napa cabbage, sesame oil, vinegar and sesame seeds. Rest 5 min.
- Heat cast iron on highest heat until smoking. Add oil, place beef ball, immediately smash flat for 10 seconds. Cook 90 seconds undisturbed.
- Flip once. Place American cheese on top. Cook 45 seconds until cheese melts over edges. Remove.
- In the same pan, add butter and toast brioche buns cut-side down 60–75 seconds until deep golden.
- Spread gochujang mayo on both bun halves. Add patty, pile kimchi slaw, scatter spring onion. Serve immediately.
Kimchi Burger — 4 Variations
Every variation below was cooked and tasted. Adjustments are specific — not just “swap the protein.”
Double Smash Kimchi Burger
Two thin patties create more caramelised surface area than one thick patty — and the cheese layer between them acts as a structural binder for the whole stack.
- Use two 110g beef balls per burger instead of one 150g ball
- Smash and cook each patty separately — do not cook together
- Cheese the first patty, stack the second on top while still on the griddle
- Add a second cheese slice on top of the stacked patties and cover with a lid for 20 seconds to melt
- Increase kimchi slaw by 30% to balance the additional beef
- Use a slightly larger brioche bun (burger-sized, not slider-sized)
Kimchi Crispy Chicken Burger
Gochujang-brined crispy chicken thigh is the Korean fried chicken answer to the classic chicken sandwich — the crunch and kimchi slaw are made for each other.
- Use 2 boneless skinless chicken thighs — brine in 1 tbsp gochujang + 1 cup buttermilk for 2–4 hours
- Dredge in seasoned flour (flour + garlic powder + gochugaru + salt)
- Deep fry or air fry at 200°C for 12–14 minutes until golden and 74°C internal temp
- Replace beef smash patty with crispy chicken thigh — keep all other components identical
- Add a thin layer of extra gochujang mayo under the chicken for maximum sauce coverage
- Add sliced pickled jalapeños for extra heat and acid contrast
Vegan Black Bean Kimchi Burger
A properly seasoned black bean patty has enough umami density to stand up to kimchi and gochujang mayo — most vegan burger recipes don’t season aggressively enough. This one does.
- Drain and rinse 1 can (400g) black beans — mash 75% with a fork, leave 25% whole for texture
- Mix with 3 tbsp breadcrumbs + 1 tbsp gochujang + 1 tsp garlic powder + 1 tsp sesame oil + salt
- Form into two patties and refrigerate 30 minutes to firm up before cooking
- Pan-fry in 2 tbsp neutral oil, medium-high heat, 3 minutes each side until dark crust forms
- Use vegan kimchi (without jeotgal), Vegenaise for gochujang mayo, and a vegan brioche bun
- Add sliced avocado to replace the richness of beef fat and cheese
Gluten-Free Kimchi Burger
Three ingredient swaps make the entire kimchi burger fully gluten-free — with no meaningful compromise to flavour or structure.
- Use a certified GF brioche-style bun (available at Whole Foods, M&S, and online)
- Verify gochujang is GF — use Bibigo certified GF version (check label for wheat)
- All other burger ingredients are naturally gluten-free
- Use tamari instead of any soy sauce if adding to marinade variations
- Kewpie mayo is gluten-free — verify the specific bottle label in your region
What to Serve With a Kimchi Burger
A kimchi burger is already a complete meal. These sides and drinks enhance the experience — they don’t compensate for anything the burger lacks.
Storage & Reheating
Store components separately. A smash burger should never be pre-cooked — the entire point is the fresh-off-the-griddle crust. The prep work, however, is fully make-ahead.
Is a Kimchi Burger Healthy?
At 520 calories, a kimchi burger is comparable to a mid-range restaurant beef burger (typically 500–700 cal) and significantly lighter than a fast food double cheeseburger (700–900 cal). The macro profile is solid for a main meal: 31g protein from 80/20 beef, 28g fat (a significant portion unsaturated from sesame oil and Kewpie), and 38g carbohydrates predominantly from the brioche bun.
The kimchi topping contributes nutritional benefits that standard burgers lack entirely. Research published in Nutrients (2021) identifies fermented kimchi as a source of Lactobacillus plantarum and Leuconostoc mesenteroides — probiotic strains associated with gut microbiome diversity. Critically: the kimchi slaw in this recipe is not cooked, meaning the live probiotic cultures remain intact in the topping. This is a meaningful distinction from recipes that cook the kimchi into the patty mixture.
The sodium content (980mg) is the primary nutritional consideration — driven largely by gochujang, soy-based Kewpie mayo and the American cheese. Reduce sodium by using low-sodium tamari in any soy applications, choosing a lower-sodium cheese, and reducing gochujang in the mayo by half.
