How to Make

  1. This recipe started with a thinly sliced flank steak which was marinated while I chopped the vegetables and prepped the sauce. I don’t own a wok so used my paella pan for this speedy entree.
  2. A large saute pan works well, too.
  3. The stir fry beef is quickly cooked, then removed from the pan so it doesn’t overcook and toughen.
  4. Next, the peppers and scallions are quickly sauteed before they are both doused in a flavorful sauce.
  5. Cook your rice concurrently so this healthy stir fry beef will be ready in less than a half-hour.

Expert Tips

My family adores beef. While I typically think of tenderloin fillets or rib eyes as “steak”, my children grew up with flank steak as another of their favorite steaks. And the price isn’t nearly as daunting as some of the finer cuts of beef. Typically, I’ll marinate our flank steaks overnight and toss them on the grill for one of our Sunday suppers.

Then I discovered flank steak is wonderful for stovetop meals as well.

  • Just be sure to watch your cooking times as this cut will be tender when cooked to a medium-rare.
  • Slicing against the grain is also the way to go. Just look for the lines or fibers running across the meat, and cut thin slices at a 45º angle to these fibers. The result will be tender slices.
  • Using a flavorful marinade or sauce really ups the wow factor of flank steak. So much better than just plain old salt and pepper.
