Gather Ingredients: Before you start, make sure all your ingredients are prepped and ready to go. This ensures a smooth cooking process.

Mix the Sauce: In a bowl, whisk together chicken broth, oyster sauce, soy sauce, fish sauce, white sugar, and brown sugar until well blended.

Heat a large skillet over high heat. Drizzle in the vegetable oil and add the chopped chicken. Stir fry the chicken until it loses its raw color, about 2 to 3 minutes.

Incorporate the sliced shallots, minced garlic, and minced chilies into the skillet. Continue cooking on high heat, stirring frequently, until some of the juices start to caramelize at the bottom of the pan, about 2 to 3 minutes more.

Add about a tablespoon of the sauce mixture to the skillet. Cook and stir until the sauce begins to caramelize, approximately 1 minute.

Pour in the rest of the sauce and continue to cook, stirring often, until the sauce deglazes the bottom of the pan. Let the sauce glaze onto the chicken for 1 to 2 more minutes before removing from heat.

Stir in the fresh basil and cook until just wilted, around 20 seconds.

Serve your Spicy Thai Basil Chicken hot with a side of fluffy rice.
