In a large pot, heat some oil over medium heat. Add the chicken and cook until browned on all sides.
Add the onion, garlic, and ginger. Cook until fragrant.
Stir in the chopped kimchi, chicken broth, gochujang, soy sauce, and sesame oil. Bring to a simmer.
Add the tofu cubes and simmer for about 15-20 minutes, until the chicken is cooked through and the flavors have melded together.
Taste and adjust seasoning if needed.
Serve the Chicken Kimchi Stew hot over cooked rice, garnished with chopped green onions.
Enjoy!
