Step 1: Prepare Your Ingredients
Start by doing all your prep work—this is called “mise en place” in cooking, and it makes everything so much smoother! Dice your onion and water chestnuts, mince your garlic and ginger, slice your green onions (keeping white and green parts separate), and mix together all your sauce ingredients in a small bowl. Carefully separate your lettuce leaves, wash them gently, and pat dry. Set aside on a serving platter.

Step 2: Cook the Aromatics
Heat a large skillet or wok over medium-high heat. Add the vegetable oil and sesame oil. Once shimmering (but not smoking), add the diced white onion and the white parts of the green onions. Sauté for 2-3 minutes until the onion becomes translucent and fragrant. Add the minced garlic and ginger, stirring constantly for about 30 seconds until wonderfully aromatic. Be careful not to let the garlic burn—if your pan is too hot, reduce the heat slightly.

Step 3: Brown the Chicken
Push the aromatics to the side of the pan and add the ground chicken to the center. Let it sit undisturbed for about 2 minutes to develop a nice brown crust, then break it up with your wooden spoon or spatula. Continue cooking for 5-7 minutes, breaking the meat into small crumbles as it cooks, until the chicken is completely cooked through with no pink remaining. The chicken should be nicely browned with some crispy bits—this adds tons of flavor!

Step 4: Add Water Chestnuts and Sauce
Stir in the diced water chestnuts and cook for 1 minute to warm them through. Give your prepared sauce a quick stir (ingredients may have settled), then pour it over the chicken mixture. Stir everything together until the sauce coats the chicken evenly. Let it simmer for 2-3 minutes, stirring occasionally, until the sauce thickens slightly and reduces. The mixture should be glossy and fragrant. Taste and adjust seasoning—add more soy sauce for saltiness, more hoisin for sweetness, or more sriracha for heat.

Step 5: Finish and Serve
Remove from heat and stir in the green parts of the sliced green onions (save a few for garnish). Transfer the warm chicken mixture to a serving bowl. Arrange your prepared lettuce cups on a platter. Let everyone build their own wraps by spooning the chicken mixture into lettuce leaves, then garnishing with additional green onions, sesame seeds, and extra sriracha if desired. Serve immediately while the chicken is warm and the lettuce is crisp!
