Three generations of this recipe. You’re welcome. The Banh Mi Burger takes everything that makes Vietnamese banh mi one of the world’s great sandwiches — the pickled daikon and carrots, the liver pâté or mayo, the cilantro and jalapeño, the crunch of fresh cucumber — and puts it on top of a properly seasoned pork patty on a toasted bun. It sounds like a novelty. It eats like a revelation.
The key is understanding what makes banh mi great. It’s not just a Vietnamese sandwich. It’s a study in contrast: rich fatty meat against bright pickled vegetables, cool cucumber against hot grilled protein, creamy mayo against crisp bread. The burger format preserves all of those contrasts while giving the pork a char and crust that the original sliced pork doesn’t always have.
The pickled vegetables are essential and can be made in 10 minutes. The pork burger is seasoned with fish sauce and lemongrass to stay connected to its Southeast Asian roots. Everything else is the construction, and the construction is what makes this worth making on a weekend when you want to cook something with intention.
Why This Banh Mi Burger Works
- Fish sauce in the pork patty: Adds umami depth and connects the burger to its banh mi roots. One tablespoon transforms the flavor of the meat completely without tasting overtly fishy.
- Quick-pickled vegetables: 10 minutes in vinegar brine is all daikon and carrots need to become the tangy, crunchy counterpoint that defines the banh mi experience.
- Sriracha mayo instead of plain mayo: Classic banh mi uses a layer of butter plus mayo. The sriracha version gives the burger its heat component in one application, bridging the traditional banh mi DNA with American burger logic.
- Toasted brioche bun: Buttered, toasted brioche has the right richness and slight sweetness to complement both the savory pork patty and the tangy pickled toppings.
Ingredients
For the Pork Patties
- 1½ lbs ground pork
- 1 tbsp fish sauce
- 2 cloves garlic, minced
- 1 stalk lemongrass, white part only, very finely minced
- 1 tsp sugar
- 1 tsp black pepper
- ½ tsp salt
- 1 tsp sesame oil
For the Quick Pickled Vegetables
- 1 cup daikon radish, julienned
- 1 cup carrots, julienned
- ½ cup rice vinegar
- ½ cup warm water
- 1 tbsp sugar
- 1 tsp salt
For Assembly
- 4 brioche burger buns
- ¼ cup mayonnaise
- 2 tbsp sriracha
- 1 English cucumber, thinly sliced
- 1 jalapeño, thinly sliced
- Fresh cilantro (generous amount)
- Butter for toasting buns
Instructions
Step 1: Make the Quick Pickles
Julienne daikon and carrots into thin matchsticks — consistent thickness ensures even pickling. Combine rice vinegar, warm water, sugar, and salt in a bowl and stir until dissolved. Add vegetables and press down to submerge. Let sit at room temperature for at least 30 minutes. The vegetables will soften slightly and turn a lighter color. Refrigerate if not using immediately. These pickles improve with time and keep for up to a week.
Step 2: Mix and Form the Patties
Combine ground pork with fish sauce, garlic, lemongrass, sugar, black pepper, salt, and sesame oil. Mix until just combined — overmixing makes the patty tough. Form into 4 equal patties, about ¾-inch thick. Make a shallow dimple in the center of each patty with your thumb — this prevents the patty from doming up during cooking and ensures even thickness throughout.
Step 3: Cook the Patties
Heat a cast iron skillet or grill over high heat. Add a drizzle of neutral oil. Cook patties for 4–5 minutes per side without pressing or moving them. Pork burgers need to reach 160°F internal temperature — verify with an instant-read thermometer. The outside should be deeply browned and slightly charred at the edges. Rest on a wire rack for 3–4 minutes before assembling.
Step 4: Toast the Buns
Butter the cut sides of each brioche bun generously. Toast cut-side down in the same pan used for the burgers, 1–2 minutes until golden. The butter gives the bun a rich, slightly crispy interior that holds up to the juicy patty and wet toppings. Toasted buns are structural — they hold the burger together instead of disintegrating on the first bite.
Step 5: Assemble
Make sriracha mayo by combining mayonnaise and sriracha. Spread sriracha mayo on both cut sides of the bun. Place pork patty on bottom bun. Top with a generous handful of pickled daikon and carrots (drain well). Add cucumber slices, jalapeño, and an abundant amount of cilantro — don’t be shy with the cilantro, it’s a structural element, not a garnish. Close the bun and serve immediately.
Tips & Common Mistakes
- Make pickles ahead: Quick pickles improve dramatically after 2–3 hours in the brine versus the minimum 30 minutes. Making them the morning of, or the night before, produces a noticeably better burger.
- Don’t underseason the pork: Ground pork is milder than beef and needs intentional seasoning. The fish sauce, lemongrass, and garlic are doing real work here — don’t halve them.
- Cook pork to 160°F: Unlike beef, pork burgers must reach 160°F internal temperature. Use a thermometer. A slightly overdone pork burger is fine; an undercooked one is a food safety issue.
- Drain pickles before adding: Watery pickles make the bun soggy. Drain well in a strainer or pat with a paper towel before building the burger.
Variations
- Beef banh mi burger: Use ground beef with the same fish sauce and lemongrass seasoning. Less traditional but works well for those who prefer beef.
- Chicken banh mi burger: Ground chicken thigh mixed with the same seasonings, formed into patties. Leaner but still excellent with the pickled toppings doing the heavy lifting.
- Pâté version: Spread a thin layer of chicken liver pâté on the bottom bun before adding the patty — this is more traditionally banh mi and adds remarkable depth if you’re a pâté person.
- Lettuce wrap format: Skip the bun and wrap everything in butter lettuce. Low-carb without losing any of the flavors that make the dish work.
The banh mi burger lives in good company: kimchi fried rice burrito, Korean BBQ tacos, katsu sando, miso glazed salmon tacos, and butter chicken flatbread pizza. All built on real technique, all fusion that actually works.
Storage & Reheating
- Cooked patties: Store in an airtight container in the fridge for up to 3 days.
- Pickled vegetables: Keep refrigerated for up to 1 week. The flavor improves over time.
- Reheating: Reheat pork patties in a hot cast iron pan with a splash of water and a lid to steam and reheat simultaneously. Or in a 350°F oven for 8–10 minutes.
- Assembled burgers: Best eaten immediately. Once assembled, the bun absorbs moisture from the pickles and deteriorates quickly.
Frequently Asked Questions
Where do I find lemongrass?
Most large grocery stores carry fresh lemongrass in the produce section. Asian grocery stores always have it. If unavailable, substitute with 1 tsp lemon zest plus ¼ tsp grated fresh ginger — it’s not identical but provides similar brightness. Lemongrass paste in a tube is also a workable shortcut.
What is daikon?
Daikon is a large white Japanese radish with a mild, slightly sweet flavor. It’s the traditional pickling vegetable in banh mi. Find it at Asian grocery stores or well-stocked supermarkets in the produce section. If unavailable, substitute with additional carrots or with thinly sliced regular radishes.
Can I make this with store-bought brioche buns?
Yes — King’s Hawaiian or any store brioche buns work well. The key is toasting them in butter in a pan, not just in the toaster. Pan-toasting in butter gives a richer, more structured surface that holds up to juicy toppings.
Is cilantro essential?
In banh mi, yes. Cilantro is a structural flavor component, not just a garnish. If you’re in the cilantro-averse camp, use fresh mint instead — it provides a similar cooling herbal note. Don’t omit fresh herbs entirely or you lose the signature freshness contrast.
