01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Wrap tofu in a clean kitchen towel and place a heavy object on top. Let drain for 10 to 15 minutes to remove excess moisture.
03 - Cut pressed tofu into 3/4-inch cubes.
04 - In a large bowl, gently toss tofu cubes with cornstarch, neutral oil, sea salt, and black pepper until evenly coated.
05 - Arrange tofu cubes in a single layer on the prepared baking sheet. Bake for 25 to 30 minutes, flipping halfway through, until golden and crispy.
06 - Whisk together peanut butter, soy sauce, toasted sesame oil, rice vinegar, maple syrup, sriracha (if using), and warm water until smooth. Adjust water to desired consistency.
07 - Transfer crispy tofu to a large bowl. Pour the sesame peanut sauce over and gently toss to coat thoroughly.
08 - Serve immediately, garnished with toasted sesame seeds, sliced green onions, and red chili if desired. Pair with steamed rice, noodles, or stir-fried vegetables.
