Homemade Stir-Fry Beef That Beats Takeout
I grabbed this beef and pepper technique from my go-to Chinese spot but tweaked it to taste even better in my kitchen. What makes it work? Soaking juicy flank steak in a mix of oyster sauce, soy sauce, cornstarch and brown sugar before cooking it up. The flavor explosion happens when your marinated meat hits those bright, colorful peppers and mixes with that deep, rich sauce. Put it on top of some hot rice and you'll wonder why you ever bothered with delivery.
Fast But Fancy
This meal nails everything you want - soft beef, crunchy peppers and a sauce that wraps it all together beautifully. There's just enough sweetness from the brown sugar to work against the umami punch of the soy and oyster sauce. What I really dig is how it doesn't take forever but tastes like it should've.
