Stir-Fried Pak Choi with Garlic Beef and Oyster Sauce

A proper, high-heat wok stir-fry where pak choi and thinly sliced beef sirloin cook together in minutes, coated in a glossy, savoury oyster sauce with plenty of garlic. The pak choi gives sweetness and texture against the umami-rich beef — both are essential, neither is an afterthought. This is exactly the kind of weeknight dinner that proves fast cooking and great flavour are not mutually exclusive.

Ingredients

  • 700 g Pak Choi, quartered lengthways if small, cut into 6 if large
  • 400 g beef sirloin or rump steak, sliced 5mm thick across the grainor use pork tenderloin, sliced the same way
  • 3 tbsp oyster sauce
  • 2 tbsp light soy sauce
  • 2 tbsp Shaoxing rice wineor use dry sherry
  • 1 tsp cornflour
  • 4 cloves garlic, finely sliced
  • 2 cm fresh ginger, peeled and cut into fine matchsticks
  • 1 tsp toasted sesame oil
  • 3 tbsp neutral oil
  • 1 tsp caster sugar

Contains: cereals gluten, molluscs, sesame, soya, sulphites.

Method

  1. In a bowl, mix the beef slices with 1 tablespoon of the soy sauce, the Shaoxing rice wine and the cornflour. Set aside to marinate while you prepare everything else — at least 10 minutes.About 10 min
  2. Mix the oyster sauce, remaining tablespoon of soy sauce, caster sugar and 2 tablespoons of water in a small bowl to make the stir-fry sauce. Set this next to the hob along with all other prepared ingredients — once cooking starts, things move fast.
  3. Heat a wok over the highest flame you have until it is visibly smoking. Add 2 tablespoons of the neutral oil and swirl to coat. Add the beef in a single layer and leave completely untouched for 60 seconds to get a sear, then stir-fry vigorously for another 60 seconds until just cooked through. Remove the beef to a plate with any juices.About 3 min
  4. Add the remaining tablespoon of oil to the wok. Add the garlic and ginger and stir-fry for 30 seconds until golden and fragrant.About 1 min
  5. Add the pak choi to the wok and stir-fry for 2–3 minutes, tossing constantly, until the leaves are wilted and the stems are tender but still have a slight crunch.About 3 min
  6. Return the beef and any resting juices to the wok. Pour over the sauce and toss everything together over the high heat for 30–60 seconds until the sauce coats everything and becomes glossy. Remove from the heat, drizzle with sesame oil, and serve immediately with steamed rice.About 1 min

Tips

  • The single most important thing in a stir-fry is heat. A domestic hob will not match a restaurant wok burner, so cook in two batches if needed rather than crowding the pan and losing temperature.
  • Slice the beef across the grain — this shortens the muscle fibres and keeps every slice tender rather than chewy.
  • Have every ingredient prepped and next to the hob before you turn it on. The whole cooking process takes 8 minutes and there is no time to chop anything once you start.

Ring the changes

  • Make it vegetarian by replacing the beef with 300g of firm tofu, cut into cubes and pressed dry, and swapping the oyster sauce for a vegetarian oyster-style sauce made from mushrooms — it is widely available.
  • Add 100g of sliced shiitake mushrooms at the same time as the pak choi for extra earthiness.

Keeping it

Best eaten straight from the wok. Leftovers keep in the fridge for 1 day and reheat well in a hot pan with a splash of water. The pak choi will soften further on reheating.

Char-Grilled Pak Choi with Sesame Miso Dressing

Halved pak choi heads go straight onto a screaming-hot griddle until the cut faces blister and the outer leaves char at the edges — that caramelisation is everything here. A nutty white miso and sesame dressing brings deep savoury warmth, and a scatter of toasted sesame seeds finishes the job. This is the side dish that makes people forget there is anything else on the table.

Pak Choi and Coconut Dal with Crispy Shallots

A creamy, gently spiced red lentil dal enriched with coconut milk and loaded with wilted pak choi stirred through right at the end so it stays bright and a little bit toothsome. The crispy fried shallots on top are not optional — they give the whole thing crunch and a savoury depth that makes this feel like far more than a midweek supper. One pot, ready in under 30 minutes, and completely vegan.

Roasted Salmon with Pak Choi, Lime and Chilli

Salmon fillets and halved pak choi heads roast together on one tray in a zingy lime, fish sauce and chilli dressing that does double duty as a marinade and a dressing for serving. The pak choi softens at the base while the leaf tips catch and crisp slightly at the edges, and the whole tray smells extraordinary. One pan, barely any washing up, and ready in well under forty minutes.
