Before you start

Before starting, ensure all ingredients are measured and ready. The slow cooker should be set up on a heat-resistant, level surface away from the edge of the counter. Prepare the green onions by washing them thoroughly, trimming the root ends, and slicing them thinly. Have your Japanese barbecue sauce and sesame seeds at hand.

If the chicken thighs are particularly large, you may trim off any excess visible fat, though leaving a little adds moisture during the long, slow cooking process. Ensure your meat thermometer is clean and calibrated to provide an accurate reading when the cooking time is nearing its end.

Ingredients at a glance (4)
  • 2 lb boneless skinless chicken thighs
  • 1/4 cup sliced green onions
  • 1 tbsp sesame seeds
  • 1 cup Japanese barbecue sauce

Instructions

Layering the chicken

  1. Prepare the slow cooker
    Place the boneless skinless chicken thighs into the basin of the slow cooker, ensuring they are arranged in an even layer to promote uniform cooking throughout the process.
    Look for The chicken should be flat at the bottom of the cooker.
    Tip Avoid overcrowding the cooker to ensure even heat distribution.

At this stage, the chicken thighs should be arranged neatly in the bottom of the slow cooker. The environment should be clean and ready for the addition of the remaining ingredients. Ensure that the chicken is not bunched up or overlapping significantly, as this allows for the most even heat distribution during the cooking cycle. Check that the slow cooker is plugged in and ready to be set to the low heat setting once the lid is secured in place.

Adding flavor components

  1. Add aromatics and sauce
    Scatter the sliced green onions and sesame seeds over the chicken. Pour the Japanese barbecue sauce over the top, coating each piece of chicken evenly with the sauce.
    Look for The sauce should settle around the chicken pieces.
    Tip Ensure the sauce covers the chicken well for maximum flavor infusion.

The chicken should now be topped with the sliced green onions and sesame seeds, with the Japanese barbecue sauce poured evenly over the top. The aromatics should be distributed across the surface to ensure their flavors permeate the sauce. Visually check that the sauce has coated the chicken pieces reasonably well. The slow cooker is now prepared for the long, slow braising process that will transform these simple components into a cohesive, flavorful finished dish.

Slow braising

  1. Cook and serve
    Cover and cook on low for 4 hours until the chicken reaches an internal temperature of 165°F (74°C). Allow the chicken to rest for 5 minutes before serving to ensure tenderness.
    Look for The chicken is tender and fully coated in a thick, glossy sauce.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Check the temperature with a meat thermometer at the thickest part.

After the cooking time has elapsed, the chicken should be thoroughly cooked and very tender. The sauce will have reduced slightly, becoming thicker and more flavorful. The aroma in the kitchen should be savory and inviting.

Before serving, use a meat thermometer to confirm the chicken has reached an internal temperature of 165°F (74°C). The meat should look moist and be easily pierced with a fork, indicating that the collagen has broken down effectively during the low-heat cooking cycle.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the chicken from cooking evenly and may result in excess liquid that dilutes the flavor of the sauce. Always aim for a single, even layer of chicken.

Another potential issue is lifting the lid too frequently during the cooking process; every time the lid is removed, heat escapes and the cooking time is extended, which can lead to unpredictable results. Avoid using high heat settings, as this can cause the sauce to scorch or the meat to become tough rather than tender. Finally, remember to always check the internal temperature.

How to tell it’s done

The chicken is done when it is fork-tender and pulls apart easily with the gentle pressure of a utensil. Most importantly, the internal temperature must reach at least 165°F (74°C) when measured at the thickest part of the meat using a digital meat thermometer.

The sauce will have thickened slightly and will appear glossy and dark, clinging to the chicken. If the chicken resists when pierced with a fork, continue cooking for an additional 20 minutes before checking the temperature again. Allowing the meat to rest for 5 minutes after cooking is essential for retaining its juices.

  • Poultry: 165°F (74°C) in the thickest part
