This is a versatile Thai recipe that easily be made vegetarian and either hot or mild, depending on your taste. But what isn’t easily interchangeable is the Thai basil. The unique flavor gives this dish a fresh and distinctly Thai flavor that you won’t be able to replicate by using another form of basil. Luckily, Thai basil is available in many supermarkets. Your search for this special ingredient will be well rewarded. You can substitute the chicken with other proteins like pork, beef, seafood or firm tofu. And for an extra treat, serve chicken basil dish “Thai style” with the addition of a crispy fried egg covering the steamed rice on the side. If you prefer a vegetarian dish you can use more mushroom and vegetables and substitute mushroom sauce for the oyster sauce.
