A quintessential Vietnamese delicacy, this stir-fry marries tender ribbons of beef with the delicate, nutty sweetness of Tonkin jasmine flowers (Hoa Thiên Lý).

This dish isn't just a meal; it's a sensory experience that captures the essence of a Vietnamese summer garden.

🥗 Ingredients

The Beef & Marinade

  • 300 grams Beef Flank or Sirloin (sliced thinly against the grain)
  • 1 tablespoon Oyster Sauce (use a high-quality brand)
  • 1 teaspoon Soy Sauce
  • 1 tablespoon Garlic (minced)
  • 1/2 teaspoon Black Pepper (freshly cracked)
  • 1 teaspoon Cornstarch (helps tenderize the meat)
  • 1 teaspoon Vegetable Oil (to coat the beef while marinating)

The Flowers & Aromatics

  • 300 grams Tonkin Jasmine Flowers (Hoa Thiên Lý) (stems trimmed, washed and drained)
  • 3 cloves Garlic (smashed and roughly chopped)
  • 1 large Shallot (thinly sliced)
  • 2 tablespoons Cooking Oil (neutral oil like canola or peanut)
  • 1 teaspoon Fish Sauce (for a final touch of umami)
  • 1/2 teaspoon Sugar (to balance the saltiness)

For Garnish

  • 2 sprigs Cilantro (for brightness)
  • 1 piece Bird's Eye Chili (sliced, optional for heat)

👨‍🍳 Instructions

  1. 1

    Place your beef in the freezer for 15 minutes before slicing; this makes it much easier to achieve paper-thin slices. Slice the beef against the grain into bite-sized pieces.

  2. 2

    In a medium bowl, combine the beef with 1 tablespoon minced garlic, oyster sauce, soy sauce, black pepper, cornstarch, and 1 teaspoon of oil. Mix well and let it marinate for at least 15-20 minutes.

  3. 3

    Prepare the Tonkin jasmine flowers by removing any tough stems or yellowing buds. Rinse them gently in a bowl of cold water and spin or pat dry thoroughly. Excess water will steam rather than stir-fry the flowers.

  4. 4

    Heat a wok or large heavy-bottomed skillet over high heat until it begins to smoke slightly.

  5. 5

    Add 1 tablespoon of oil and swirl to coat the pan. Add half of the chopped garlic and shallots, tossing for 10 seconds until fragrant.

  6. 6

    Add the marinated beef to the wok. Spread it out in a single layer and let it sear for 30 seconds without moving it to get a nice browning.

  7. 7

    Stir-fry the beef rapidly for another 1-2 minutes until it is about 80% cooked (still slightly pink in the center). Remove the beef and any juices from the wok and set aside on a plate.

  8. 8

    Wipe the wok clean if necessary and add the remaining 1 tablespoon of oil over high heat.

  9. 9

    Add the remaining garlic and shallots. Once they sizzle, toss in the Tonkin jasmine flowers.

  10. 10

    Stir-fry the flowers quickly for about 1-2 minutes. They should turn a vibrant, bright green and soften slightly but still retain a crisp 'snap'.

  11. 11

    Return the beef and its accumulated juices back into the wok with the flowers.

  12. 12

    Season with the fish sauce and sugar. Toss everything together for 30-45 seconds to allow the flavors to meld and the beef to finish cooking.

  13. 13

    Immediately transfer the dish to a serving platter. Overcooking the flowers will cause them to turn yellow and lose their delicate aroma.

  14. 14

    Garnish with freshly cracked black pepper, cilantro, and sliced chilies if desired.

💡 Chef's Tips

Always slice beef against the grain to ensure every bite is tender rather than chewy. Do not overcrowd the pan; if your wok is small, stir-fry the beef in two batches to maintain high heat. Tonkin jasmine flowers cook very quickly; they only need a 'breath of the wok' to be ready. If you cannot find Tonkin jasmine, young zucchini blossoms or even garlic chives are acceptable substitutes, though the flavor profile will change. Adding a teaspoon of oil to the marinade prevents the beef slices from clumping together in the hot wok.

🍽️ Serving Suggestions

Serve immediately with a bowl of steaming jasmine rice to soak up the savory juices. Pair with a side of 'Nước Chấm' (Vietnamese dipping sauce) or a simple bowl of soy sauce with sliced chilies for extra seasoning. Accompany with a light Vietnamese clear soup (Canh) like melon or spinach soup for a complete family-style meal. A crisp, chilled lager or a refreshing iced jasmine tea complements the floral notes of the dish beautifully.
