Follow the steps in order for the best result.
Begin by heating a large skillet over medium-high heat. Add the oil and let it shimmer.
Add the minced garlic to the hot oil, cooking until fragrant, being careful not to burn it.
Introduce the thinly sliced chicken to the skillet, followed by the fish sauce, oyster sauce, sugar, and white pepper. Ensure the chicken is evenly coated with the sauce.
Increase the heat to high, allowing the sauce to reduce and thicken into a luscious glaze. This process should take a few minutes, stirring frequently.
If the sauce remains too thin, gradually add the cornstarch mixture while stirring continuously until the desired consistency is achieved.
Incorporate the roasted cashews into the skillet, ensuring they are well-mixed with the chicken and sauce.
Transfer the cashew chicken mixture to a serving dish.
Garnish generously with chopped green onion and sliced red bell pepper for a vibrant presentation and added flavor.
Serve immediately with fluffy jasmine rice for a complete and satisfying meal.
