Beef Lo Mein

This classic beef lo mein is a vibrant, high-protein stir-fry that brings the bold flavours of a takeaway into your own kitchen. Succulent strips of flank steak are seared alongside crisp mangetout and sweet red peppers, then tossed with tender noodles in a rich, savoury glaze. Using honey and rice wine vinegar provides a perfect balance of sweetness and acidity, ensuring every strand of noodle is coated in a glossy, umami-rich sauce.

Ideal for a nutritious midweek dinner, this dish is both satisfying and incredibly quick to prepare. By slicing the beef thinly and cooking it over a high heat, you achieve a tender texture that pairs beautifully with the fresh, crunchy vegetables. Serve it straight from the wok for a wholesome, homemade meal that is far superior to any shop-bought alternative.

Cook noodles in a medium pot of boiling salted water according to package directions. Drain and rinse with cool water; set aside.

Meanwhile, whisk oyster sauce, soy sauce, vinegar, and honey together in a medium bowl.

Slice beef against the grain as thinly as possible. Transfer to a medium bowl and toss with 1/2 teaspoons salt and 1/2 teaspoons pepper.

Heat 2 tablespoons oil in a large wok or skillet over high. Add beef and cook, tossing often, until medium-rare, about 3 minutes. Transfer to a plate.

Heat remaining 1 teaspoon oil in same skillet over high. Cook garlic, ginger, and half of the spring onions, stirring, for 30 seconds. Add peas and pepper and cook until vegetables are softened, about 1 minute. Add oyster sauce mixture and reserved noodles and cook, tossing with tongs, until everything is coated and sauce thickens slightly, 1–2 minutes more. Add beef and stir to combine.

Divide among plates and top with remaining spring onions.
