Nam Tok Neua is a Thai grilled beef salad from the Isan region, dressed with fish sauce, lime, palm sugar, and birdโs eye chilies, then finished with roasted rice powder for a nutty crunch. It comes together in 30 minutes and costs far less than ordering it out. The dressing does most of the heavy lifting, so even a modest cut of beef tastes sharp and satisfying.
Before you start
Two things determine whether this salad works. First, get the steak to room temperature before it hits the pan โ a cold center means youโll overcook the outside trying to hit medium-rare. Second, slice strictly against the grain and keep the slices thin, around โ inch. Sirloin has long muscle fibers; cut with the grain and even a perfectly cooked steak will be chewy. Both steps take almost no extra time and make a real difference in the final texture.
Troubleshooting
- Dressing tastes flat or one-dimensional: Fish sauce and lime juice vary a lot by brand and fruit. Taste the dressing before it goes on the salad and adjust โ a little more lime if itโs too salty, a pinch more sugar if itโs too sharp.
- Roasted rice powder clumping or turning gummy: This happens if the salad has been sitting. Add the powder at the very last moment, right before it goes to the table, not during assembly.
- Beef releasing too much liquid into the salad: The steak needs the full 5-minute rest. Slice it too soon and the juices pool in the bowl, diluting the dressing and making everything wet.
- Chilies too hot to eat: Birdโs eye chilies are genuinely fierce. If youโre heat-sensitive, use one instead of three, or substitute a small amount of red chili flakes where you can control the quantity more precisely.
- Shallots taste harsh or sharp: Soak sliced shallots in cold water for 10 minutes, then pat dry. This takes the raw edge off without losing the crunch.
Shopping notes
- Roasted rice powder (khao khua): Sold in Asian grocery stores, but easy to make at home โ toast raw sticky rice (glutinous rice) in a dry skillet over medium heat, stirring constantly, until golden and nutty-smelling, about 8โ10 minutes, then grind in a spice grinder or with a mortar and pestle. Regular long-grain rice works if sticky rice isnโt available; the flavor is slightly less nutty but still good.
- Palm sugar: Found in most Asian grocery stores, usually in disks or tubs. Brown sugar is a solid substitute โ same quantity, slightly more molasses flavor, which works fine here.
- Fish sauce: Tiparos, Megachef, or Tra Chang are reliable Thai brands. Avoid generic supermarket versions if you can; the flavor difference is noticeable in a dressing this simple.
- Sirloin: Ribeye works well and is more forgiving if you slightly overshoot the cook time, since the fat keeps it moist. Flank steak is a leaner, cheaper option โ slice it especially thin.
Keeping leftovers crisp
Dress it at the table โ a pre-dressed salad goes limp fast. If youโre making this ahead, keep the sliced beef, vegetables, and dressing in separate containers in the fridge. The beef holds well for up to 2 days; the sliced cucumber and herbs are best used within 24 hours before they soften. When youโre ready to serve, bring the beef to room temperature for about 10 minutes, then toss everything together and add the roasted rice powder last. Once dressed, the salad should be eaten within an hour.

Ingredients
Salad Ingredients
- 1 pound sirloin steak preferably grass-fed for optimal flavor
- ยผ cup roasted rice powder for fragrant texture
- 2 small shallots thinly sliced
- ยผ cup mint leaves fresh and fragrant
- ยผ cup cilantro leaves chopped
- 1 medium cucumber sliced thinly
- 3 stalks spring onions sliced diagonally
Dressing Ingredients
- 3 tablespoons fish sauce quality Thai brand preferred
- 2 tablespoons lime juice freshly squeezed
- 1 tablespoon palm sugar can substitute with brown sugar
- 3 small bird's eye chilies finely chopped
Instructions
- Preparing the Steak - Season the sirloin steak with salt and allow it to reach room temperature. Heat a grill or pan over high heat and sear the steak for about 3-4 minutes on each side or until a desirable medium-rare, registering 54ยฐC (129ยฐF) on a meat thermometer.
- Resting the Steak - Let the steak rest covered loosely with foil for 5 minutes, allowing juices to reabsorb.
- Making the Dressing - In a bowl, combine fish sauce, lime juice, palm sugar, and chopped chilies. Stir until the sugar has dissolved.
- Assembling the Salad - Thinly slice the rested steak against the grain. In a large bowl, toss together the steak slices, shallots, mint, cilantro, cucumber, and spring onions. Pour the dressing over and toss to combine.
- Adding Roasted Rice Powder - Just before serving, sprinkle the roasted rice powder over the salad for a dry, aromatic crunch.

FAQ
Can I use a different cut of beef if sirloin isnโt available?
Yes โ flank steak or skirt steak both work well and are often cheaper. Slice them especially thin against the grain, since these cuts have more pronounced muscle fibers than sirloin.
I donโt have sticky rice for the roasted rice powder. Can I skip it or use something else?
Regular long-grain white rice toasted in a dry pan and ground coarsely is a workable substitute. The texture and nutty aroma are slightly less pronounced, but it still adds crunch and body to the salad โ donโt skip it entirely.
What can I use instead of palm sugar if I canโt find it?
Brown sugar is the most practical swap, used in the same quantity. Light brown sugar is closer in flavor; dark brown sugar adds a stronger molasses note but still balances the dressing.
Is there a substitute for fish sauce?
For a non-fish option, use soy sauce or tamari in the same amount โ the recipe card already notes this for the vegetarian version. The umami depth is similar, though the flavor profile shifts slightly.
How do I know when the steak is at medium-rare without a thermometer?
Aim for an internal temperature of 129ยฐF (54ยฐC), but if you donโt have a thermometer, press the center of the steak โ it should feel like the fleshy base of your thumb when your hand is relaxed, with a little give but not soft. A 3โ4 minute sear per side on a properly preheated high-heat pan gets most ยพ-inch sirloin steaks there.
Can I make the dressing in advance?
Yes, the dressing keeps in a sealed jar in the fridge for up to 5 days. Give it a stir before using, since the sugar can settle, and taste it again โ lime juice mellows slightly over time and may need a small squeeze more.
