Stir-Fried Beef Strips with Bok Choy

A high-heat stir-fry is all about speed and contrast. In this quick skillet meal, thin ribbons of flank steak get a deep sear before giving way to halved baby bok choy, which wilts slightly while keeping a satisfying, juicy crunch. Fresh ginger and minced garlic bloom instantly in the residual heat, pulling the whole dish together. Because the entire cooking process takes only minutes once the pan is hot, having your aromatics prepped and greens washed beforehand makes everything flow smoothly from stove to table.
Why this one works
- Thinly sliced flank steak browns quickly over high heat without turning tough.
- Baby bok choy provides a crisp, refreshing texture alongside the savory beef.
- Freshly grated ginger and minced garlic create an aromatic baseline without heavy sauces.
- Toasted sesame oil added at the finish delivers a rich, nutty fragrance.

What you’ll need
- 1 pound (450g) flank steak, sliced thin Slice across the grain into thin strips so the meat remains tender when seared.
- 4 cups (800g) baby bok choy, halved Rinse thoroughly between the outer leaves to remove any trapped grit, then pat dry so it sears rather than steams.
- 3 tablespoons (45ml) soy sauce Provides the primary savory, salty foundation that coats the beef and greens at the end.
- 2 cloves garlic, minced Tossed in with the greens so it softens and perfumes the pan without burning.
- 1 tablespoon (15ml) ginger, grated Brings a sharp, warm zing that cuts through the rich beef.
- 1 tablespoon (15ml) sesame oil Stirred in right at the end to preserve its fragrant, toasted flavor.

Step-by-step instructions
Stir-frying works best when you divide the cooking into stages. Searing the beef on its own prevents the pan from overcrowding, letting you achieve deep browning before quickly cooking the vegetables and finishing with the seasoning.
- 1Step 1
Heat a wok over high heat with oil. Add beef and sear until browned.
- 2Step 2
Remove beef. Add bok choy, garlic, and ginger, stir-frying until tender.
- 3Step 3
Return beef to pan. Toss with soy sauce and sesame oil. Serve immediately.

A few things worth knowing
- Get your wok thoroughly hot before adding the beef so you get an immediate sear rather than simmering the meat.
- Dry the halved bok choy completely after washing to help it blister and tenderize in the hot pan.
- Toss the soy sauce and sesame oil in just before removing from the heat to avoid burning the sauce.
Ways to make it your own
- Sprinkle lightly with toasted white sesame seeds just before serving for extra crunch.
- Garnish with thinly sliced scallions for a mild, fresh onion bite.
Serving suggestions
Serve immediately while the wok is still steaming. The savory pan juices pair naturally with a bowl of steamed white or brown rice, or alongside plain noodles or cauliflower rice.
Storage & reheating
Transfer any leftovers to an airtight container and refrigerate promptly. Reheat gently in a warm skillet over medium heat just until heated through to keep the beef tender.

Quick recipe answers
How do I make flank steak easier to slice thinly?+
Placing the beef in the freezer for about 15 to 20 minutes before prep firms it up, making it much simpler to cut clean, thin strips across the grain.
Can I use a standard skillet instead of a wok?+
Yes, a wide, heavy stainless steel or cast-iron skillet works well. Ensure it is heated thoroughly so the ingredients sear quickly.
With its balance of tender steak, crisp greens, and aromatic ginger, this stir-fry delivers bold, savory flavor with minimal fuss at the stove.
