In a small bowl, whisk together the chicken broth, oyster sauce, light soy sauce, dark soy sauce, fish sauce, and sugar. Set aside.
Heat up a large frying pan or wok and add in 2 tablespoon oil.
Add in the shallots, garlic, Thai chilies and quickly stir fry until fragrant, about 1 minute.
Next, add in the ground chicken and break it up with a wooden spoon. Cook until no longer pink, about 2-3 minutes.
Pour in the chicken broth mixture and stir to coat the chicken. Be sure to scrape off any brown bits on the bottom of the pan. Continue to cook.
When most of the chicken broth has evaporated, turn off the heat and add in a large handful of Thai basil.
Stir to incorporate the basil into the chicken as the residual heat will continue to wilt the basil. Remove from heat.
Serve the Thai Basil Chicken with fresh hot steamed rice and a fried egg. Garnish with additional basil leaves. Best served hot.
