01 - Preheat oven to 425°F and line a baking sheet with parchment paper.
02 - Wrap tofu in a clean kitchen towel and place a heavy object on top. Drain for 10–15 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 coated tofu cubes in a single layer on the prepared baking sheet. Bake for 25–30 minutes, flipping halfway, until golden and crisp.
06 - Whisk together peanut butter, soy sauce or tamari, toasted sesame oil, rice vinegar, maple syrup or honey, sriracha if using, and warm water until smooth. Adjust water for desired consistency.
07 - Transfer crispy tofu to a large bowl and pour over the sesame peanut sauce. Gently toss to coat evenly.
08 - Serve immediately, garnished with toasted sesame seeds, sliced green onions, and red chili if desired. Accompany with steamed rice, noodles, or vegetables.
