Step 1

Wrap the tofu in a clean dish towel and place on top of a wire rack set inside a rimmed baking sheet. Place a heavy pan on top of the tofu and let it sit for 5 minutes to release as much moisture as possible. Unwrap the tofu and slice lengthwise into 1/2-inch-thick by 1 1/2-inch-wide planks.

Step 2

Whisk the soy sauce, lime juice, agave syrup, scallion whites and sriracha together in a small bowl and set aside. Mix the panko, sesame seeds, cornstarch, garlic salt, onion powder, 1/2 teaspoon kosher salt and a few grinds of pepper in a pie dish or shallow bowl. Press the tofu planks into the panko mixture to coat on all sides.

Step 3

Heat the olive oil in a large skillet over medium-high heat. Add the tofu and cook, undisturbed, until deep golden brown, 4 to 5 minutes. Flip the tofu with a metal spatula and continue cooking undisturbed until a deep golden brown, 4 to 5 minutes more. Transfer to a platter.

Step 4

Reduce the heat to low and add the soy-sauce mixture to the pan. Cook until bubbling and slightly thicker, 1 to 2 minutes. Pour the sauce over the tofu planks and sprinkle with the scallion greens.
