Vietnamese Rice Noodle Salad (Bún Chay) with Lemongrass Tofu
Michelle Davis
Bún Chay is a Vietnamese rice vermicelli salad built on cool noodles, crisp vegetables, and fresh herbs, all dressed with a bright, tangy vegan nước chấm. Lemongrass-marinated tofu is pan-seared until caramelized and layered on top for savory, citrusy depth. The whole bowl comes together in about 40 minutes and balances sweet, sour, salty, and heat in every forkful.

Instructions
Quick-pickle the carrot and daikon (10 minutes rest). Whisk together 1/2 cup warm water, 1/2 cup rice vinegar, 2 tbsp sugar, and 1 tsp kosher salt until dissolved. Add the julienned carrot and daikon, press to submerge, and let sit for 10 minutes. The brine should taste bright-sour with gentle sweetness; veggies will stay crisp.
Press and marinate the tofu (8 minutes press + 7 minutes marinate). Wrap the 14 oz tofu in a clean towel and place a light weight on top for 8 minutes to quickly expel surface moisture. Meanwhile, mix 2 tbsp minced lemongrass, 2 tsp garlic, 2 tbsp shallot, 2 tbsp soy sauce or tamari, 1 tbsp maple syrup, 1 tsp lime zest (optional), and 1 tbsp neutral oil. Pat tofu dry, cut into 1/2-inch slabs or cubes, and toss gently in the marinade. Rest for 7 minutes; the tofu should smell citrusy and aromatic.
Make the vegan nước chấm (5 minutes). In a small bowl, whisk 1/4 cup lime juice, 3 tbsp soy sauce or tamari, 2 tbsp rice vinegar, 3 tbsp warm water, 1 1/2 tbsp maple syrup, 1 tsp chili-garlic sauce (or sliced chili), and 1 tsp grated garlic until translucent and glossy. Taste for a balanced sweet-sour-salty-heat profile and adjust as desired.
Cook and chill the rice vermicelli (about 4 minutes). Bring a pot of water to a rolling boil (212°F / 100°C). Add 8 oz rice vermicelli and cook per package, usually 3–4 minutes, until just tender and bouncy. Drain immediately and rinse under very cold water until cool; shake off excess water. Toss with a few drops of neutral oil to prevent sticking and set aside.
Sear the lemongrass tofu (about 11 minutes). Heat 2 tbsp neutral oil in a nonstick skillet or wok over medium-high heat until the oil shimmers (pan surface will be very hot; if oven-baking, preheat to 425°F / 220°C). Lay tofu in a single layer and cook 3–4 minutes per side until deep golden and lightly crisp. Alternative: Deep-fry at 350°F / 175°C for 3–4 minutes, or oven-bake for 18–20 minutes, flipping halfway.
Assemble and plate (about 5 minutes). In wide bowls, create a bed with 4 cups shredded lettuce. Add a nest of chilled noodles, then arrange cucumber, bean sprouts, and a generous handful of mixed herbs (mint, Thai basil, cilantro). Spoon over the vegan nước chấm to lightly gloss the noodles. Top with hot lemongrass tofu, a tangle of pickled carrot and daikon (drained), crushed peanuts, fried shallots, and lime wedges. Look for a mosaic of greens, ivory noodles, golden tofu, and ruby chili—this color story signals perfect balance.
Notes
Michelle’s Tips
Maximize herb fragrance: Tear herbs by hand just before serving to release essential oils without bruising.
Quick-press tofu hack: Microwave tofu for 30 seconds, then press for faster water release without crumbling.
Sharper lemongrass: Bruise minced lemongrass with the side of your knife or a mortar to unlock citrusy oils. If you don't have a mortar and pestle, pulse aromatics briefly in a food processor; texture will be slightly finer.
Gluten-free: Use tamari and ensure fried shallots/peanuts are GF-certified.
Mild heat: Remove chili seeds and ribs, or replace with a few drops of chili oil at the table.
Crunch insurance: Rinse noodles very well in cold water; this halts cooking and preserves their bounce.
Alternative tofu methods: Air-fry at 400°F / 205°C for 12–14 minutes, shaking once, for extra-crisp edges.
Serving Suggestions
Plating: Use wide, shallow bowls. Twirl noodles into a compact nest with chopsticks, then tuck vegetables and herbs around for contrast. Lay tofu at 10 and 2 o'clock so it crowns the bowl.
Garnish: A final squeeze of lime, a sprinkle of crushed peanuts, and a few mint tips add sparkle. For aroma, finish with a whisper of freshly cracked black pepper.
Pairings: Serve with iced jasmine tea, a crisp pilsner, or a lime soda. A side of torn lettuce for wrapping bites is wonderfully interactive.
Culinary Context
Bún Chay is a beloved Vietnamese staple, especially in the South, where herbs are plentiful and salads are meals unto themselves. Traditionally assembled to order, each bowl balances the elemental Vietnamese flavor compass—sour (lime, vinegar), salty (soy/tamari), sweet (maple), spicy (chili), and bitter (herbs). I fell in love with its market-stall energy—the way a vendor's practiced hands build layers of texture and brightness in seconds.
Optional Advanced Instructions
Make-ahead: Quick pickles keep 1 week in the fridge; dressing keeps 5 days. Press and marinate tofu up to 24 hours ahead for deeper flavor.
Parallel cooking: While tofu marinates, boil water and prep herbs. Chill noodles while you sear tofu to serve hot-on-cold for a dynamic contrast.
Beginner alternative: If searing feels tricky, oven-bake the tofu at 425°F / 220°C for 18–20 minutes; it's forgiving and evenly browns.
