Quick Beef Stir Fry in 25 Minutes

A fast, weeknight-friendly beef stir fry with tender strips of steak, crunchy peppers and a savoury soy-based sauce. Everything cooks in one hot pan in minutes, so slicing and prep is the only real work. Serve over rice or noodles for a proper takeaway-beating dinner.

The secret to a great beef stir fry is speed and heat: get everything sliced before the pan even sees a flame, then cook fast and hard so the beef stays tender and the veg keeps its bite. This version leans on storecupboard soy, garlic and ginger for a glossy sauce that clings to every strip. Rice or noodles, and dinner is sorted.

Ingredients

• 500 g beef rump or sirloin steak — thinly sliced against the grain
• 2 tbsp vegetable or groundnut oil
• 1 red pepper — deseeded and sliced
• 1 green pepper — deseeded and sliced
• 200 g tenderstem broccoli or mangetout
• 3 garlic cloves — finely chopped
• 20 g fresh ginger — peeled and grated
• 4 spring onions — sliced, green and white kept separate
• 3 tbsp light soy sauce
• 1 tbsp dark soy sauce
• 1 tbsp oyster sauce
• 1 tsp caster sugar
• 1 tbsp cornflour — mixed with 3 tbsp cold water
• 1 tsp toasted sesame oil

Method

1. Slice the beef as thinly as you can against the grain, then pat dry with kitchen paper. In a small bowl, whisk together the light and dark soy, oyster sauce, sugar and cornflour slurry, and set aside.
2. Get all your veg, garlic, ginger and spring onions prepped and within arm's reach, as the cooking goes quickly. Have a serving plate ready.
3. Heat a wok or large frying pan over the highest heat until smoking. Add 1 tbsp of the oil, then the beef in a single layer. Leave it undisturbed for 30 seconds to sear, then stir-fry for 1 to 2 minutes until browned and just cooked through with no pink remaining. Tip onto a plate.
4. Add the remaining oil to the pan, then the peppers and broccoli. Stir-fry over high heat for 2 to 3 minutes until glossy and just tender but still crisp.
5. Add the garlic, ginger and the white parts of the spring onions. Stir-fry for 30 seconds until fragrant, taking care not to let the garlic catch and burn.
6. Return the beef and any resting juices to the pan. Give the sauce a quick stir and pour it in. Toss everything together for 1 to 2 minutes until the sauce thickens to a glossy coat and the beef is piping hot throughout.
7. Take off the heat, drizzle over the sesame oil and scatter with the green spring onion tops. Serve straight away over rice or noodles.

Serve it with

• Steamed jasmine or basmati rice
• Egg noodles tossed with a little sesame oil
• Egg-fried rice
• A simple cucumber and sesame salad
• Prawn crackers on the side

Why this works

Slicing against the grain and searing over fierce heat keeps the beef tender rather than tough, while the cornflour slurry turns the soy and oyster sauce into a glossy coating that clings to every piece.

Common swaps

• Swap the steak for beef stir-fry strips to save on slicing.
• Use tenderstem, mangetout, baby corn or sliced carrots depending on what's in the fridge.
• No oyster sauce? Use an extra tablespoon of soy plus a splash of hoisin.
• Add a chopped red chilli or a spoon of chilli bean paste for heat.
• Make it gluten-free with tamari in place of the soy sauces.

Common mistakes to avoid

• Overcrowding the pan, which steams the beef instead of searing it. Cook in two batches if your pan is small.
• Cooking over medium heat. Stir-frying needs the pan properly hot for that quick sear and bite.
• Slicing the beef with the grain, which leaves it chewy. Always cut across the grain.
• Overcooking the veg until soft. It should stay crisp and vibrant.

Storage, freezing & reheating

Storage: Cool leftovers quickly and keep in an airtight container in the fridge for up to 2 days.

Reheating: Reheat in a hot pan or wok for 2 to 3 minutes, stirring, until piping hot throughout. Add a splash of water if the sauce has thickened too much.
