Instructions 

  • In a bowl, combine the cubed chicken thighs with Shaoxing wine, salt, and cornstarch. Mix thoroughly and marinate for 15 minutes.

Why I Love This Chicken Onion Stir Fry

For me, this Chicken Onion Stir Fry checks all the boxes of a great meal. It’s quick, tasty, and also relatively healthy. The chicken is juicy from the velveting process, and the onions are soft, but still have that signature bite that is so delicious. Additionally, the sauce thickens into almost like a glaze and coats every piece of chicken and onion. Especially when you serve it over rice, the grains soak up the sauce too, making every bite heaven, even the rice!

What Makes This Chicken Onion Stir Fry So Good

In my opinion, marinating the chicken is a non-negotiable in this recipe. Not only does the shaoxing wine and cornstarch make the chicken more tender, but it also helps it get that amazing sear that you can’t usually get without marinating it. The onions also aren’t just a filler to give the stir fry extra volume, but they also add their own layer of flavors to the dish as well. When cooked in the pan, they soften and release their natural sweetness, which plays with the natural umami and savory flavors of the sauce. It’s that balanced flavor profile of the sauce and all the ingredients that makes this dish so good.

Tips and Variations

If it’s difficult to get a good sear on your chicken, cook the chicken in batches so the pan stays hot and the pieces brown instead of steam.


If you’re an onion lover like me, slice the wedges even larger so they hold their shape and texture while cooking.

For an even darker and more umami flavor, add even more dark soy sauce.


Frequently Asked Questions

Can I use chicken breast instead of thighs?

Yes, but chicken breast cooks faster and can dry out more easily, so if you use it, reduce the cooking time slightly.

Why is cornstarch added to the chicken?

Cornstarch forms a light coating that helps the chicken brown and also keeps the chicken tender.

Can I make this ahead of time?

This dish is perfect for meal prepping! Once cooked and cooled, place your Chicken Onion Stir Fry in an airtight container  and store in the fridge for up to 4 days.
