This Vietnamese chicken vermicelli salad is fresh, vibrant, and packed with texture from tender chicken, cool noodles, crisp vegetables, and fragrant herbs. A bright, tangy nuoc cham dressing ties everything together for a light but satisfying meal that works well for lunch or dinner.
In a medium bowl, combine the chicken thighs with the garlic, lime juice, fish sauce, soy sauce, and brown sugar. Toss well to coat, then let the chicken marinate at room temperature for 30 to 60 minutes while you prepare the remaining ingredients.
Make the nuoc cham by stirring together the vinegar, sugar, cold water, fish sauce, lime juice, and sliced red chili in a small bowl. Mix until the sugar fully dissolves, then taste and adjust with more lime juice, sugar, or fish sauce if needed.
Cook the rice vermicelli according to the package directions until just tender. Drain immediately, rinse under cold running water to stop the cooking, and let the noodles drain well.
Heat the vegetable oil in a skillet or grill pan over medium-high heat. Add the chicken and cook for about 4 minutes per side, or until nicely browned and cooked through. Transfer to a plate and let it rest for a few minutes, then slice thinly.
Divide the rice vermicelli among serving bowls or a large platter. Top with the bean sprouts, julienned carrot, cucumber, romaine lettuce, mint, cilantro, and sliced chicken. Spoon the nuoc cham over the salad just before serving, or serve it on the side.
Do not overcook the vermicelli or it can turn gummy; rinse it well and drain thoroughly before assembling. Chicken breast can be used instead of thighs, but cook it carefully so it stays juicy. The dressing can be made up to 2 days ahead and refrigerated, and leftovers are best stored with the dressing kept separate.
