This recipe takes the classic Vietnamese lemongrass marinade — lemongrass, garlic, sugar, black pepper — and puts it on tofu instead of chicken. Pressing the tofu first gives it a firm, crispable exterior; searing it hot gives the sauce something to cling to; and a tangle of fresh herbs at the end keeps it bright.
Note that this version is genuinely meat-free: it uses soy sauce, not fish sauce, so the seasoning stays plant-based from start to finish.
Ingredients
Serves 4 over rice.
- 1 block (14 oz) extra-firm tofu
- 2 stalks fresh lemongrass, tough outer layers removed, finely minced (about 1/4 cup)
- 3 cloves garlic, minced
- 2 tbsp soy sauce (or tamari for gluten-free)
- 1 tbsp sugar
- 1 tbsp neutral oil, plus 2 tbsp more for searing
- 1/2 tsp freshly ground black pepper
- 1 Thai chile, sliced (optional)
- 1 cup mixed fresh herbs: Thai basil, cilantro, and mint — roughly equal parts
- 1 tbsp lime juice, plus lime wedges for serving
Method
- Drain the tofu. Press it for 30 minutes: wrap in clean towels or paper towels, set a plate on top, and weigh it down with a heavy pan or cans. Longer pressing gives firmer, crispier tofu.
- Cut the pressed tofu into 3/4-inch cubes or slabs. Pat each piece dry with fresh towels — surface moisture is what keeps tofu from browning.
- Toss the tofu with the minced lemongrass, garlic, soy sauce, sugar, 1 tbsp oil, pepper, and chile. Let it sit 15 minutes while you prep the herbs.
- Heat 2 tbsp oil in a large nonstick or well-seasoned skillet over medium-high heat. Sear the tofu in a single layer, undisturbed, about 3 minutes per side, until golden and crisp on at least two sides. Work in batches if the pan is crowded.
- Turn off the heat, squeeze over the lime juice, and toss with the fresh herbs just before serving — the residual heat wilts them slightly without killing them.
- Serve over rice with extra herbs and lime wedges.
Tips and ingredient notes
- Tofu firmness: extra-firm is the pick; firm works if pressed longer. Silken or soft tofu will fall apart — do not substitute.
- Moisture control: pressing is the single most important technique in this recipe. A second dry with paper towels right before the pan is worth it.
- Herbs: Thai basil is the most characteristic; cilantro and mint round it out, in roughly equal parts.
- Gluten-free: use tamari and check the label. Coconut aminos are sweeter and less salty — a possible substitution, not the default.
- Honest limit: this is a home adaptation of the Vietnamese flavor palette on tofu, not a traditional temple-vegetarian dish.
Storage and food safety
Allergen note: contains soy (soy sauce); check labels for wheat/gluten if that matters to you. Tofu is a perishable protein: keep it refrigerated until use, do not leave it at room temperature for more than 2 hours, and refrigerate leftovers promptly. Reheat leftovers until steaming hot.
