Instructions

  1. Step 1: Heat 2 tablespoons vegetable oil in a large skillet over medium-high heat. Add 14 ounces cubed firm tofu and cook, turning occasionally, for 6-8 minutes until all sides are golden brown and crispy. Remove tofu and set aside.
  2. Step 2: In the same skillet, add 1 tablespoon vegetable oil, 1 finely minced lemongrass stalk, and 2 minced garlic cloves. Sauté for 1-2 minutes until fragrant.
  3. Step 3: Add 1 medium sliced red bell pepper and 1 medium sliced yellow bell pepper to the skillet. Stir-fry for 3-4 minutes until vegetables are tender-crisp.
  4. Step 4: Return tofu to the skillet and add 2 tablespoons soy sauce, 1 teaspoon brown sugar, and 1 tablespoon lime juice. Toss to coat everything evenly and cook for 1 more minute until sauce thickens slightly.
  5. Step 5: Remove from heat and garnish with 2 chopped scallions and 1/4 cup chopped fresh cilantro before serving.

How do I scale Stir-Fried Lemongrass Tofu with Bell Peppers for a different number of people?

The recipe is written for 3 servings. Multiply each ingredient by (your serving target / 3). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
