Before you start

Before you begin, ensure you have all your ingredients measured and prepped. Slice the chicken breast into uniform strips and clean the shiitake mushrooms thoroughly to remove any grit. Have your slow cooker clean and positioned on a stable, heat-resistant surface.

If you are serving this with rice, start your rice cooker or stovetop pot now, as the rice will need to be ready precisely when the chicken finishes its slow-cooking cycle to ensure a hot, cohesive meal.

Ingredients at a glance (10)
  • 2 lb chicken breast, sliced into strips
  • 8 oz shiitake mushrooms, sliced
  • 1 can baby corn
  • 1 can water chestnuts
  • 1/3 cup oyster sauce
  • 1/4 cup soy sauce
  • 1 tbsp toasted sesame oil
  • 1 cup chicken broth
  • 2 cups roasted whole cashews
  • 2 stalks green onion tops, thinly sliced

Instructions

Preparation and Layering

  1. Combine Ingredients
    Place the sliced chicken breast, shiitake mushrooms, baby corn, and water chestnuts into the slow cooker ceramic insert. Pour the oyster sauce, soy sauce, toasted sesame oil, and chicken broth over the top of the mixture.
    Look for Ensure all ingredients are evenly distributed and the liquid coats the chicken and vegetables well.
    Tip Layer the tougher vegetables at the bottom for more even cooking.

At this phase, your slow cooker should be filled with the chicken, mushrooms, and vegetables. The sauce ingredients should be poured over the top, creating a rich, dark base. Ensure that the chicken is not clumped together so that the heat can circulate effectively through all the meat strips during the initial phase of the slow-cooking process.

Simmering Transformation

  1. Slow Cook
    Cover the slow cooker with its lid and set to cook on LOW for three hours. This slow process allows the chicken to become tender while absorbing the savory garlic and oyster sauce flavors, reaching a safe internal temperature of 165°F (74°C).
    Look for The chicken should be fully cooked, tender, and opaque throughout.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Avoid lifting the lid during the first two hours to maintain consistent heat.

After three hours of cooking, the kitchen should be filled with a savory, garlicky aroma. The chicken will be fully cooked and tender, and the mushrooms will have softened significantly. Check that the liquid has reduced slightly and formed a cohesive, glossy sauce that coats the back of a spoon, indicating it is ready for the final step.

Final Garnish and Serving

  1. Finish and Serve
    Once the cooking time is complete, remove the lid and stir in the roasted whole cashews to maintain their crunch. Ladle the cashew chicken over steamed brown rice and garnish with thinly sliced green onion tops before serving immediately.
    Look for The sauce should be glossy and the cashews should be well incorporated.
    Tip Add the cashews at the very end so they stay crunchy rather than becoming soft in the sauce.

The final phase involves folding in the crunchy cashews and adding the fresh green onions. The dish should look vibrant, with the deep brown sauce contrasting against the light-colored baby corn and the bright green onion tops.

Ensure the cashews are evenly distributed throughout the mixture before spooning the finished dish over a generous serving of steamed brown rice.

Common mistakes

A common mistake is adding the cashews too early; if they sit in the hot sauce for the entire three-hour cooking duration, they will lose their signature snap and become unpleasantly soft. Another error is overcrowding the slow cooker with too many vegetables, which can release excessive liquid and dilute the flavor of the oyster-garlic sauce.

Finally, ensure the lid remains closed during the cooking cycle, as lifting it releases heat and steam, which significantly increases the total cooking time required for the chicken to become tender.

How to tell it’s done

The chicken is done when it is opaque, tender, and reaches an internal temperature of 165°F (74°C). The sauce should be slightly thickened and glossy. Because this is a slow-cooker recipe, the chicken should pull apart easily with a fork while retaining its shape.

Ensure the internal temperature is verified with a digital meat thermometer inserted into the thickest piece of chicken to guarantee food safety before serving the meal to your guests or family.
