Notes
Tips and Tricks
Cut the chicken into equal-sized pieces. This will help ensure they all cook evenly.
Do not skip battering and frying the chicken. This gives this sweet and sour chicken that traditional Chinese takeout flavor and texture.
Let the sauce thicken before adding the chicken.
Prep the gluten-free chicken batter ahead of time. - You can prep the batter a day ahead and keep it in a sealed container in the fridge.Make the sauce ahead of time. - I find it easiest to mix the sauce without the vegetables and let it simmer on the stove just until it starts to thicken. Then, when I am cooking dinner, it takes less time to finish once the sauce is added to the vegetables.Make it all ahead of time and reheat. - This isn't my favorite option, but it does work. You can thoroughly batter and fry the chicken and make the sauce beforehand.
I recommend storing the battered chicken and the sauce separately if you do this.
The gluten-free battered chicken gets crispier if it's reheated in the oven or air fryer without the sauce.
When making the sauce ahead of time, warm it up and then combine it with the chicken for the best results.
