This is a ground chicken burger seasoned with lemongrass, garlic, fish sauce, and hoisin, topped with quick-pickled carrot and daikon. The honest reason to make it: the pickles take 30 minutes of passive time and the patties cook in under 20 minutes, so the whole thing comes together faster than it looks. It’s lighter than a beef burger and noticeably more interesting than a plain grilled chicken patty.
Before you start
The two things that actually matter here are the lemongrass prep and keeping the patties cold before they hit the pan. Lemongrass has a tough outer layer that stays fibrous no matter how long you cook it — peel down to the pale, tender inner core and mince it as fine as you can, otherwise you’ll get woody bits in every bite. As for the patties: ground chicken is soft and sticky, and a 10-minute rest in the fridge after shaping firms them up enough to hold together when they hit a hot surface. Skip that rest and they’ll spread and stick. One more thing worth knowing — skip the temptation to press the patties down while they cook; ground chicken is already lean and pressing squeezes out the moisture you need to keep them from drying out.
Troubleshooting
- Patties fall apart in the pan: Ground chicken has less fat than beef and doesn’t bind as easily. If yours are crumbling, your mixture is probably too warm. Put the bowl in the fridge for 10 minutes before forming, and handle the mix as little as possible.
- Pickles taste flat after 30 minutes: The brine needs the sugar and salt fully dissolved before the vegetables go in — if you added them while the liquid was still grainy, pull the veg out, re-stir the brine until clear, and return them. Another 10 minutes usually fixes it.
- Patties are cooked through but dry: Medium-high heat is right for color, but ground chicken goes from done to dry fast. Use a thermometer and pull at exactly 165°F (74°C) — don’t cook to a visual cue alone. Resting the patty on the bun for 90 seconds while you assemble helps retain juice.
- Chili mayo is too thin and slides off: Standard mayo straight from the fridge is thick enough, but if yours has been sitting out or is a low-fat version it can get runny. Spread it on the cut face of the toasted bun and let the bun soak it in slightly before stacking — it won’t pool at the bottom.
- Lemongrass flavor is barely noticeable: Three stalks sounds like a lot, but lemongrass loses punch when mixed into a protein. If yours tastes mild, the inner core wasn’t minced finely enough. A microplane or the fine side of a box grater works better than a knife for getting maximum flavor out of it.
Leftovers and meal prep
Cooked chicken patties keep in an airtight container in the fridge for up to 3 days. Reheat them in a dry skillet over medium heat for about 3 minutes per side — the microwave works but makes them rubbery. The pickled vegetables actually improve after 24 hours in the fridge and will keep for up to a week in their brine, so making a double batch of those ahead is worth it. Raw formed patties can be frozen between sheets of parchment for up to 2 months; thaw overnight in the fridge before cooking, not on the counter. The chili mayo can be mixed and refrigerated up to 5 days in advance. If you’re prepping for the week, the brine and the mayo are the two things to make first — both hands-off, both done in one bowl each.
Vietnamese Lemongrass Chicken Burger
Ingredients
Burger Patties
- 500 grams ground chicken preferably free-range
- 3 stalks lemongrass finely minced, use the tender inner core
- 2 cloves garlic minced
- 1 tablespoon fish sauce
- 1 tablespoon hoisin sauce
- 1 teaspoon sugar
Pickled Vegetables
- 1 cup carrot julienned
- 1 cup daikon radish julienned
- ½ cup rice vinegar
- ½ cup water
- 2 tablespoons sugar
- 1 teaspoon salt
To Assemble
- 4 medium burger buns preferably brioche
- 1 cup fresh cilantro roughly chopped
- 1 small cucumber sliced into ribbons
- ½ cup mayonnaise mixed with a pinch of chili powder
Instructions
Prepare the Pickled Vegetables:
- Combine rice vinegar, water, sugar, and salt in a bowl. Stir until sugar and salt are fully dissolved.
- Add julienned carrot and daikon radish to the mixture. Let them pickle for at least 30 minutes.
Make the Chicken Patty:
- In a large mixing bowl, combine ground chicken, minced lemongrass, garlic, fish sauce, hoisin sauce, and sugar.
- Mix gently until the ingredients are just combined. Overmixing can make the patties tough.
- Form into four equal patties and refrigerate for about 10 minutes to firm them up.
Cooking the Patties:
- Heat a grill or frying pan over medium-high heat, about 190°C / 375°F.
- Cook patties for 6-8 minutes on each side or until the internal temperature reaches 75°C / 165°F, ensuring a light char and golden-brown exterior.
Assemble the Burgers:
- Toast the brioche buns lightly for a crisp texture.
- Spread the spiced mayonnaise on both halves of each bun.
- Place a chicken patty on the bottom half, followed by pickled vegetables, cucumber ribbons, and fresh cilantro. Top with the other half of the bun.

Your questions, answered
Can I use lemongrass paste from a tube instead of fresh stalks?
Yes, but use about 1.5 teaspoons per stalk as a starting point and taste the raw mix before forming patties, since tube paste varies a lot in concentration. Fresh gives a brighter, cleaner flavor, but the paste is a reasonable substitute when fresh lemongrass isn’t available.
Do I have to use daikon, or can I substitute something else?
Thinly sliced radishes or even shredded green cabbage work fine in the brine. Daikon is milder and holds its crunch well, but the substitution won’t break the burger — you’re mainly after the pickled tang and texture contrast.
Can I grill these patties on an outdoor grill instead of a pan?
You can, but ground chicken patties are stickier than beef and more likely to tear on grill grates. Oil the grates well and don’t try to flip until the patty releases cleanly on its own — usually after 6 minutes. A grill basket is the easier option if you have one.
Is there a substitute for fish sauce if I don’t have it or want to avoid it?
Soy sauce works as a 1:1 swap and keeps the salt and umami without the fish flavor. The patty will taste slightly different but still good — just don’t skip the liquid entirely, since it helps season the meat evenly.
How do I know the patties are fully cooked without a thermometer?
Get a thermometer — ground poultry needs to hit 165°F (74°C) and there’s no reliable visual shortcut. A basic instant-read probe costs under $15 and is the only way to be sure without cutting the patty open and losing juice.
Can I make the patties ahead of time and cook them the next day?
Yes, formed raw patties keep in the fridge for up to 24 hours, covered tightly. Beyond that the fish sauce starts to break down the texture of the meat, so freeze them if you need more lead time.
