In a bowl, combine the chicken with soy sauce, ginger, garlic, salt, pepper, and cornstarch. Let it marinate for at least 30 minutes.
Soy sauce, Cornstarch
Heat oil in a pan and fry the marinated chicken until it turns golden and crispy. Remove and set aside.
Boneless chicken breasts or thighs
In the same pan, sauté garlic and ginger. Add onions, bell peppers, and sauces (ketchup, soy sauce, chili sauce). Simmer for a few minutes.
Ginger and garlic, Various sauces
Mix cornstarch with water and add it to the pan. Cook until the sauce thickens.
Add the fried chicken to the pan and toss it well in the sauce until fully coated.
Garnish with spring onions and coriander leaves. Serve the Chicken Manchurian as an appetizer or with rice or noodles.
