This recipe is from our cookbook, Lunch Box.
Refreshing and tasty Vietnamese banh mi rolls are a perfect workday lunch. We used beef but it also works a treat with chicken breast fillets.


  • 1/4 cup (75g) whole-egg mayonnaise
  • 3 tsp sriracha or other chilli sauce (optional)
  • 2 short baguettes, ends trimmed, halved crossways
  • 2 baby cucumbers (qukes), cut into batons
  • 1 carrot, julienned
  • 1 green onion, cut into 5cm lengths
  • 8 large fresh coriander sprigs
Lemongrass beef
  • 300 grams beef porterhouse or rump steak, fat trimmed, sliced thinly on the diagonal
  • 1 tablespoon fish sauce
  • 1 stalk fresh lemongrass, white part only, chopped finely
  • 1 clove garlic, crushed
  • 1 tablespoon vegetable oil
  • 1 red shallot, halved, sliced thinly
  • 2 teaspoons white sugar


  • 1
    Place beef, fish sauce, half the lemon grass and half the garlic in a bowl; stir to mix well. Refrigerate, covered, for at least 30 minutes for flavours to develop.
  • 2
    Heat a wok or large heavy-based frying pan over high heat. Add half the oil; stir-fry beef for 4 minutes or until browned. Transfer to a plate. Heat remaining oil in wok; stir-fry shallot, remaining lemon grass and garlic for 2 minutes or until fragrant. Return beef to wok, then add sugar; stir-fry to combine for 30 seconds. Season to taste with pepper.
  • 3
    Combine mayonnaise and chilli sauce in a small bowl.
  • 4
    Split baguette pieces lengthways from the top, without cutting all the way through. Spread sides with mayonnaise mixture; fill baguettes evenly with lemon grass beef, cucumber, carrot, green onion and coriander. Drizzle with extra mayonnaise mixture.


  • Use one long baguette cut into quarters instead of half baguettes, if preferred.
  • The lemongrass beef can be made up to 2 days in advance and refrigerated in an airtight container.
  • Make banh mi the night before or in the morning. Wrap banh mi in baking paper or pack in airtight containers. Transport in cooler bags. Refrigerate until ready to serve.
