Dice 1 cup of red onion and thinly slice the remaining 1/4 red onion into half-moons. Place the sliced onions in a small bowl and pour the boiling water over them, then add the seasoned rice vinegar. Set aside to pickle while you prepare the remaining ingredients—this develops flavor while you work. Mince the garlic, finely mince the lemongrass, and finely dice the Thai bird's eye chilies. Slice the cucumber (removing seeds first to prevent excess moisture), thinly slice the radishes, chop the scallions, and roughly chop the cilantro, mint, and Thai basil. This prep work ensures everything cooks smoothly without interruption.

Heat the olive oil in a large pan over medium-high heat. Add the diced red onion and sauté for 3-4 minutes until softened and slightly translucent. Add the minced garlic, lemongrass, and chili flakes, stirring constantly for 2-3 minutes until fragrant—this technique, called blooming aromatics, releases their essential oils and deepens their flavor. I find that cooking these together creates a more cohesive, complex base than adding them separately.

Add the ground chicken to the aromatic base along with the sea salt and cracked black pepper. Break up the meat with a wooden spoon as it cooks, stirring frequently for about 10 minutes until the chicken is completely cooked through and the mixture becomes dry and crumbly (excess moisture should evaporate). This drying is key to larb—it allows the meat to absorb the dressing better and creates the signature texture. I like to keep stirring constantly near the end to ensure even cooking and to help release any remaining moisture.

Remove the pan from heat and immediately stir in the 1 tbsp of toasted rice powder, mixing thoroughly until the powder is fully incorporated throughout the meat. The rice powder adds a subtle nutty flavor and helps absorb any remaining moisture. Let the mixture cool for a minute or two before moving to the next step.

Drain the pickled onions from their liquid and add them to a large mixing bowl along with the cooled larb mixture from Step 4. Add the cucumber, radishes, scallions, cilantro, mint, Thai basil, and fresh diced chilies. In a small bowl, whisk together the fish sauce, fresh lime juice, and brown sugar until the sugar dissolves. Pour this dressing over the salad and toss gently but thoroughly until everything is evenly coated. Taste and adjust seasonings as needed—the balance of salty (fish sauce), sour (lime), and sweet (sugar) is crucial to authentic larb.

Arrange butter lettuce or red leaf lettuce leaves on a serving platter or individual plates as a base. Spoon the larb salad mixture onto the lettuce leaves, then sprinkle the 2 tbsp of toasted rice powder evenly over the top for garnish and added texture. Serve immediately while the larb is still warm and the salad greens are fresh and crisp. You can also serve with the cooked jasmine rice on the side for those who prefer it, or simply enjoy the larb on its own as a lighter option.
