Ingredients

  • 1 pack tofu (10–12 oz / 300–350 g, see Note 1)
  • 2 stalks lemongrass, finely minced (or 3–4 tbsp frozen minced lemongrass, see Note 2)
  • 1 Thai chili peppers, deseeded and minced (optional, for heat)
  • ½ tsp salt
  • ½ tbsp vegetable bouillon powder
  • tbsp light soy sauce
  • 1 tbsp sugar
  • Cooking oil (enough to pan-fry the tofu)
  • 1 tsp Vietnamese lemongrass chili oil (sa tế) (optional)

Instructions

Prepare the tofu

  • Cut the tofu into bite-sized pieces about 0.6 inch (1.5 cm) thick.
  • On the larger flat surface of each piece, make light criss-cross cuts so the marinade can absorb better.
  • Pat the tofu dry with kitchen paper.

Marinate

  • Mix the salt and vegetable bouillon powder.
  • Gently massage this mixture onto all sides of the tofu.

Prep the aromatics & sauce

  • Trim off the tough parts of the lemongrass and finely mince the rest. If you're using frozen minced lemongrass, you can skip this step. Mince Thai chili peppers as well.
  • Stir together the light soy sauce and sugar until dissolved.

Fry the tofu

  • Heat a skillet over medium-high heat and add the oil.
  • When the oil is hot (bubbles form around chopsticks), fry the tofu until golden and crispy on all sides. Transfer to a plate and set aside.

Combine & Serve

  • Pour out excess oil, leaving about 1 tbsp in the pan.
  • Add minced lemongrass and chili. Stir-fry until fragrant and lightly golden. Add sa tế if using.
  • Lower the heat and pour in the soy-sugar sauce.
  • Once the sauce bubbles, add the fried tofu back in and toss quickly so each piece is coated evenly.
  • Enjoy hot with steamed jasmine rice or rice noodles.

Notes

Note 1 (Tofu): Fresh tofu is best. If using packaged tofu, choose soft → medium-firm → firm. Avoid silken tofu.
Note 2 (Lemongrass): A food processor works best for mincing lemongrass to keep it from being gritty.
