Tips For Success
Cut beef opposite the grain for softness. Got thick sauce? Thin it with water drops. Want some kick? Throw in red pepper flakes. The rice really soaks up that yummy sauce.

Ways To Serve
We usually go for jasmine rice but noodles work too. Cutting down on carbs? Try cauliflower rice instead. Some cooked bok choy makes a nice veggie side.
Storage Tips
You can keep extras in your fridge for up to three days. Heat it back up in a skillet with a tiny bit of water. Don't try freezing it though – the sauce gets funky after thawing.
Mix It Around
I often throw in some mushrooms or bell peppers. It's just as good with shrimp or chicken too. If you want it hot, mix in some chili sauce while you're cooking.
Common Questions
Can't get flank steak? Sirloin cuts work just fine. No Shaoxing around? Just use rice vinegar. Going gluten-free? Swap for tamari instead. Don't worry if you don't have a wok – a normal frying pan works great.
Total Comfort Food
This stir fry always gets happy faces at our table. It's fast enough for crazy weeknights but fancy enough for guests. Make it once and you'll see why I always count on it.
