Stir-Fried Pork with Long Beans

This aromatic stir-fried pork with long beans is a vibrant example of Thai-inspired home cooking, bringing together a perfect balance of salty, sweet, and spicy flavours. The heart of the dish lies in a handcrafted spice paste, where fresh lemongrass, galangal, and kaffir lime zest are pounded together to create a deeply fragrant base. By using a stone mortar and pestle, you release the essential oils from the aromatics, resulting in a far superior depth of flavour compared to shop-bought alternatives.

As a high-protein main course, this dish is both satisfying and nutritious. The tender pork shoulder pairs beautifully with the crunch of the long beans, while the final addition of minced lime leaves provides a bright, citrusy finish. It is an ideal choice for a midweek dinner that feels truly special. For a complete and authentic meal, serve it alongside a generous portion of fluffy steamed jasmine rice to soak up the savoury juices.

How to make Stir-Fried Pork with Long Beans

Mince 1 tablespoon lemongrass from root end. Put minced lemongrass and remaining paste ingredients in mortar and vigorously pound to a smooth paste using pestle (most chilli seeds should be crushed), 6 to 8 minutes.

Cook beans in a medium saucepan of boiling salted water (1 teaspoon salt for 1.9L water), uncovered, until crisp-tender, about 3 minutes. Drain and transfer to a bowl of cold water to stop cooking. Drain again.

Pat pork dry, then cut across the grain into ÿ-inch-thick slices (about 2 by 1 inch).

Heat oil in a 12-inch skillet over high heat until it shimmers, then cook seasoning paste, stirring constantly, until fragrant, about 1 minute. Add pork, tossing to coat, then spread out in skillet and brown, turning occasionally (to keep paste from burning), about 2 minutes. Add fish sauce, palm sugar, and beans and cook, tossing, until pork is just cooked through and beans are hot, about 1 minute. Remove from heat and toss with lime leaves.
