1-Step 1: Prepare and Marinate the Chicken Start by cutting your boneless chicken into uniform 3/4-inch cubes. Uniform pieces ensure even cooking throughout the sous vide process. In a medium bowl, combine the chicken cubes with the soy sauce, dark soy sauce (if using), brown sugar, rice vinegar, oil, minced garlic, and minced ginger. Use your hands to gently massage the marinade into the chicken for about 30 seconds. This brief massage helps the flavors begin to penetrate the meat. Do not skip this step. Even a quick massage distributes the marinade more evenly than simply stirring.

2-Step 2: Vacuum Seal and Refrigerate Transfer the chicken and all the marinade into a sous vide bag or a resealable freezer bag. Arrange the chicken in a single, flat layer within the bag. This ensures even heat circulation during cooking. Remove as much air as possible before sealing. Place the sealed bag in the refrigerator and let it marinate for at least 40 minutes. You can extend this up to 4 hours for deeper flavor, but avoid going beyond 4 hours. The salt in the soy sauce can make the chicken overly salty or affect the texture if left too long.

3-Step 3: Cook in the Sous Vide Water Bath Preheat your sous vide water bath to 150°F. This temperature is the sweet spot for chicken. It cooks the meat to a safe temperature while maintaining incredible juiciness and a texture that mimics traditional cooking methods without any raw or mushy consistency. Once the water bath reaches temperature, submerge the sealed bag completely. Cook the chicken for 1 to 4 hours. For optimal results, I recommend cooking for at least 3 hours. This longer cook time allows fat to render and connective tissue to break down, resulting in exceptionally tender meat, especially when using chicken thighs. According to cooking experts at Serious Eats, sous vide cooking transforms simple ingredients into something extraordinary with precise temperature control. Even if you are short on time, the 1-hour minimum still produces juicy chicken. The beauty of sous vide is its flexibility. You cannot overcook the chicken as long as you stay within the recommended time range.

4-Step 4: Create the Sauce When the cooking time is complete, remove the bag from the water bath. Carefully cut a small slit in one corner of the bag and drain all the cooking liquid into a large nonstick pan. Do not discard this liquid. It contains concentrated chicken flavor and all the marinade ingredients. In a small bowl, whisk together the 2 teaspoons of cornstarch and 1 tablespoon of water to create a slurry. This prevents lumps when thickening the sauce. Pour the slurry into the pan with the cooking liquid and stir to combine. Turn the heat to medium-high and bring the mixture to a gentle simmer. Stir constantly for 2 to 3 minutes until the sauce thickens to a glossy consistency that coats the back of a spoon. The sauce should cling to the chicken rather than run off.

5-Step 5: Add the Chicken and Finish Now add the cooked chicken pieces from the bag directly into the pan with your thickened sauce. Use tongs or a spoon to toss and coat each piece evenly. The chicken is already fully cooked, so this step is about glazing rather than additional cooking. Cook for just 1 to 2 minutes, tossing frequently, until the sauce caramelizes slightly and coats the chicken in a sticky, savory glaze. Remove from heat immediately. Sprinkle generously with sesame seeds for garnish. Serve your sous vide sesame chicken hot over steamed rice, cauliflower rice, or your favorite grain. For a complete meal, pair it with a simple vegetable side or a fresh salad. If you have a sweet tooth, consider serving this alongside a slice of peach cobbler for dessert. This dish also makes an excellent filling for rice bowls, lettuce wraps, or Asian-inspired tacos. The possibilities are endless with this versatile recipe.
