Why You’ll Love This Lemongrass Tofu Recipe

Lemongrass tofu is a simple, crowd-pleasing dish that tastes way fancier than it is. This Vietnamese-inspired stir-fry uses basic, budget-friendly ingredients for a bold, vibrant, flavor-packed dish. It’s quick and simple enough for weeknights, but impressive enough for guests.

Even better, there’s no marinating. Just pan-fry the tofu until crispy and toss it in the aromatic glaze made with ingredients like lemongrass, garlic, onion, soy sauce, and brown sugar, for a perfectly balanced sweet, tangy, savory flavor in 30 minutes. Garnish with peanuts and fresh herbs like cilantro, Thai basil, or mint for extra flavor, and enjoy over rice, noodles, in spring rolls (like these fresh rainbow rolls), and more.

How to Make Lemongrass Tofu

Step 1: First, if you haven’t already, drain and press the tofu for 30 minutes, pat dry, and cut into ½-1-inch cubes. Also, mince the lemongrass, and thinly slice the onion and garlic. Then, in a small bowl, whisk the lemongrass, vinegar, soy sauce, brown sugar, water, and cornstarch. Set aside.

Step 2: Heat the oil in a large skillet over medium-high heat. Pan-fry the tofu in a single layer for 3-5 minutes per side until golden brown and crispy all over. Set on a paper towel-lined plate (to absorb excess oil).

To prepare lemongrass: Trim the wooden ends, remove tough outer layers, then tenderize the bulbous part with a rolling pin. Slice in half lengthwise, then once more, and finely chop.

Step 3: Sauté the onion and garlic for 3-4 minutes until tender and slightly charred. Add the pan-fried tofu and lemongrass sauce mixture and stir to coat the tofu.

Step 4: Once the sauce has thickened, turn off the heat, cover with a lid, and let it sit for 5 minutes for the flavors to absorb. Toss the lemongrass tofu stir-fry once more, optionally garnish with chopped peanuts and green onion (or cilantro). Enjoy!

FAQs

Can I use frozen lemongrass?

Absolutely! First thaw it first, then chop.

Could I bake or air-fry the tofu instead?

Bake tofu in a single layer on a tray, sprayed with oil, for about 30 minutes at 400°F/200 °C, flipping halfway, OR air fry for 12-15 minutes.

Pro Recipe Tips

  • Press the tofu: For the best texture and sauce absorption. Refer to this guide to pressing tofu.
  • For tender tofu: Freeze and thaw the tofu before using it. It becomes chewier and ‘meatier’.
  • Save lemongrass scraps: The woody, dry bits can be used for lemongrass tea, soups (removed before serving), etc.
  • For the crispiest tofu: Lightly dust it with cornstarch and don’t move it around while pan-frying – cook untouched until crispy on each side.
  • Taste and adjust: Tweak any sauce element – sweet, acid, salt, etc.

Serving Suggestions

Storage Instructions

Fridge: Store tofu with lemongrass sauce in an airtight container for 4 days.

Freezer: In a freezer-safe container for up to 3 months, then thaw in the refrigerator overnight. Just note that the texture becomes spongier/’meatier’. Don’t freeze it if you use frozen tofu.

Reheat: In a microwave or in a skillet over medium heat until heated through.
