How Recipesdarleen publishes recipes

Twelve ingredients and thirty-five minutes, and most of the thirty-five is knife work rather than cooking.

Everything hinges on heat. The wok goes very hot, the beef goes in batches, and the broccoli comes out while it is still bright and firm.

Why This Recipe Works

  • Slicing very thin across the grain shortens the muscle fibres so wide slices stay tender.
  • Searing in batches keeps the pan hot enough to brown rather than steam.
  • Two tablespoons of water steam the broccoli just enough without dulling its colour.
  • Sliced garlic added late stays visible and sweet instead of burning.
  • A cornstarch slurry at the end is what takes the sauce glossy rather than watery.

Ingredient Notes

Flank steak
A pound and a quarter, sliced very thin across the grain. Across the grain is what makes wide slices tender rather than chewy.
Sliced garlic
Four cloves, sliced rather than minced. Slices are visible in the finished bowl and take thirty seconds of heat, no more.
Red pepper flakes
A quarter teaspoon. Not named in the recipe title and clearly there in the sauce.
Cornstarch slurry
Two teaspoons in a tablespoon of water, stirred in at the very end. It is what makes the sauce glossy and cling.

How to Make It

  1. Whisk the sauce before the heat goes on

    Whisk soy sauce, broth, oyster sauce, vinegar, brown sugar, and sesame oil.

  2. Very hot wok, beef in batches

    Heat a wok until very hot. Sear beef in batches so the wide slices brown quickly; transfer out.

  3. Broccoli bright and crisp-tender, then the aromatics

    Stir-fry broccoli with 2 tablespoons water until bright green and crisp-tender. Add sliced garlic and red pepper flakes for 30 seconds.

  4. Beef back in, sauce boiled, slurry to gloss

    Return beef, add sauce, and bring to a boil. Stir in cornstarch slurry and toss until glossy.

  5. Into the bowl, no rice and no noodles

    Serve without rice or noodles.

Everything Here Is About Keeping the Wok Hot

This beef and broccoli is cooked fast, and the reason is what you are after: BROWNED beef slices and BRIGHT FIRM broccoli are things only fast, high heat produces. Each rung below protects that heat.

  1. Mix the sauce firstBefore any heat

    1/3 cup low-sodium soy sauce, 1/2 cup low-sodium beef broth, 1 tbsp oyster sauce, 1 tbsp rice vinegar, 2 tsp brown sugar and 1 tsp toasted sesame oil, whisked together BEFORE the wok is lit. Six ingredients is too many to measure while a very hot pan waits - and every second the wok idles is heat lost.

  2. Slice very thin, ACROSS the grainWide slices, not cubes or strips

    1 1/4 lb of FLANK STEAK. Flank is a lean, strongly grained cut, which makes the direction of the knife decisive: across the grain shortens the fibres so WIDE SLICES stay tender. Thin also means the slices cook through in the seconds a sear allows.

  3. Sear IN BATCHES, then take it outAt least 145F for the beef; do not undercook

    The wok heated UNTIL VERY HOT, then the beef in batches. This is the rung the whole dish rests on: a wok loaded all at once drops below searing temperature, the beef releases its juices, and it stews grey instead of browning. Out of the pan after searing, so it is not overcooking while the broccoli goes.

  4. Broccoli with 2 tbsp water, and 30 seconds of garlic30 seconds for the aromatics

    3 cups of florets with just 2 TABLESPOONS of water, stir-fried until BRIGHT GREEN AND CRISP-TENDER. A splash rather than a pour: enough steam to cook the stems, not enough to flood the pan or to dull the colour. Then 4 cloves of SLICED garlic and 1/4 tsp of red pepper flakes for THIRTY SECONDS - both visible components the title never names, and thirty seconds is the window where sliced garlic sweetens without catching.

  5. Reunited, boiled, then glossedUntil glossy

    The beef returned, the sauce added, brought to a BOIL, then 2 tsp of cornstarch slaked in 1 tbsp of water stirred in and tossed until GLOSSY. The boil is what activates the starch; the slurry is what turns a thin brown liquid into a clinging coat. Then straight into bowls - with NO RICE AND NO NOODLES.

Success Tips

  • Slice the beef as thin as your knife allows, and always across the grain.
  • Wait for the wok to be genuinely hot before the first batch of beef.
  • Pull the broccoli while it still has bite; it keeps cooking in the sauce.

Serving Ideas

Four servings in pale bowls, the thin wide slices of browned beef and bright green florets in a glossy dark brown sauce with sliced garlic and red chilli flakes. No rice and no noodles.

Frequently Asked Questions

Why sear the beef in batches?

A crowded wok drops in temperature and the beef releases its juices and steams. In batches, each slice meets hot metal and browns.

Does slicing across the grain matter?

With flank steak, very much. Across the grain shortens the fibres, which is what lets wide slices stay tender in a fast sear.

Is it served with rice?

No — the bowl is served on its own, without rice or noodles.
