Black-Bean Prawns with Chinese Broccoli

This vibrant black bean prawns with Chinese broccoli is a nutritious, diabetes-friendly dish that captures the authentic essence of Cantonese home cooking. The combination of succulent prawns and the slight bitterness of gai lan provides a wonderful contrast in textures, all tied together by a savoury, aromatic sauce. Using fermented black beans and fresh ginger creates a deep, umami-rich base that feels indulgent while remaining light and heart-healthy.

Perfect for a quick midweek meal, this high-protein stir-fry is both satisfying and balanced.

  • 675g gai lan (Chinese broccoli)

  • 675g large prawns in shell (21 to 25 per lb), peeled and deveined

  • 1 tablespoon peanut or vegetable oil

  • 1 (1-inch) piece fresh ginger, peeled and cut into very thin matchsticks

  • 2 tablespoons fermented black beans, rinsed and chopped

  • 2 garlic cloves, minced

  • 1/2 fresh jalapeño chilli (including seeds), or to taste, cut crosswise into 1/8-inch-thick slices

  • 1 teaspoon Asian sesame oil

How to make Black-Bean Prawns with Chinese Broccoli

Stir together broth, rice wine, soy sauce, cornflour, sugar, and salt in a small bowl until cornflour is dissolved.

Remove any bruised or withered outer leaves from gai lan, then trim and peel stalks, halving thick ones lengthwise. Cut crosswise into 2 1/2-inch pieces, separating leafy parts from thick stems.

Cook stems in a 6- to 8-quart pot of boiling salted water, uncovered, until crisp-tender, about 3 minutes. Add leafy parts and cook until all of gai lan is just tender, 3 to 5 minutes. Drain well, then transfer to a clean kitchen towel and pat dry. Transfer to a large dish and keep warm, loosely covered with foil.

Pat prawns dry. Heat wok over high heat until a drop of water vaporizes instantly. Pour peanut oil around side of wok, then tilt wok to swirl oil, coating side. When oil just begins to smoke, add ginger and stir-fry 5 seconds. Add black beans, garlic, and jalapeño and stir-fry 1 minute. Working quickly, add prawns, spreading in 1 layer on bottom and side of wok. Cook, undisturbed, 3 minutes, then stir-fry until prawns are just pink on both sides, about 1 minute more. Stir broth mixture, then add to prawns and bring to a boil. Boil, stirring, 2 minutes. Remove from heat and drizzle with sesame oil, then stir to combine.

Pour prawns and sauce over gai lan.
