Rump is perfect for a fast, saucy stir-fry. Here’s a recipe for a tender, glossy version with crisp veg and proper wok flavour. It uses easy pantry ingredients and a quick velveting step so the beef stays juicy.
Rump Stir-Fry (serves 3–4)
Beef & velvet
500–600 g rump steak, trimmed, sliced thinly against the grain
½ tsp bicarbonate of soda (baking soda) (for tenderness)
1 Tbsp soy sauce
1 Tbsp oyster sauce
1 Tbsp cornflour (cornstarch)
1 tsp oil
Sauce (mix in a jug)
3 Tbsp soy sauce
2 Tbsp oyster sauce
2 Tbsp rice vinegar (or 1½ Tbsp apple cider vinegar + ½ Tbsp water)
1 Tbsp brown sugar (or honey)
½ cup (120 ml) beef or chicken stock
1 tsp cornflour
Veg & aromatics
1 small onion, sliced
2 bell peppers, sliced (any colours)
1 cup tenderstem broccoli or green beans, bite-size
1 cup snap peas or carrots, sliced
3 garlic cloves, finely chopped
1 Tbsp grated fresh ginger
Optional: 1 fresh chilli, sliced (or ½–1 tsp chilli flakes)
2–3 Tbsp neutral oil
1 tsp toasted sesame oil (to finish)
To serve: steamed rice or noodles, lime wedges, spring onion, toasted sesame seeds/peanuts.
Velvet the beef (15 min): Toss sliced rump with the bicarb. Rest 15 minutes, then rinse well and pat very dry.
Marinate: Mix beef with 1 Tbsp soy + 1 Tbsp oyster + 1 Tbsp cornflour + 1 tsp oil. Rest while you prep veg and sauce.
Preheat hard: Get a wok or big heavy pan ripping hot. Add 1 Tbsp oil.
Sear beef in batches: Stir-fry beef in 2–3 quick batches, ~60–90 seconds each, just until browned. Tip out to a bowl. (Don’t crowd or it steams.)
Stir-fry veg: Add another Tbsp oil. Fry onion 30 sec, then peppers, broccoli/beans, and snap peas/carrots 2–3 min until bright-crisp. Add garlic, ginger, chilli; toss 30 sec until fragrant.
Combine: Return beef (and any juices). Stir sauce (cornflour settles), pour in. Toss 30–60 sec until glossy and just thickened.
Finish: Off the heat, drizzle sesame oil. Taste—add a splash of soy for salt, vinegar for brightness, or a pinch of sugar if you like it rounder.
Serve: Over rice or noodles. Top with spring onion, sesame seeds/peanuts, squeeze of lime.
Saucy noodles: Add 100–150 ml extra stock for more sauce; toss through cooked noodles at step 6.
Local wink: Stir in 1 tsp Mrs Ball’s at the end for a sweet-tangy glaze.
Gluten-free: Use tamari and GF oyster sauce.
No bicarb? Skip step 1 and add 1 egg white to the marinade; still tender.
Wok heat hack: If your stove runs mild, heat the empty pan 2–3 min, then cook smaller batches.
