01 - Set the oven to 400°F and line a baking sheet with parchment paper.
02 - Combine white miso paste, tamari, grated ginger, maple syrup, olive oil, rice vinegar, minced garlic, thyme leaves, and black pepper in a large bowl; whisk until smooth.
03 - Add the pressed, cubed tofu to the marinade and toss gently to coat evenly. Let sit for at least 10 minutes, up to 30 minutes for enhanced flavor.
04 - Distribute the marinated tofu, sliced red onion, and cranberries in a single layer on the prepared baking sheet.
05 - Bake for 30 to 35 minutes, flipping midway through, until tofu is golden and crisp and cranberries have burst.
06 - Transfer to a serving plate, garnish with additional thyme sprigs and toasted sesame seeds if desired, and serve warm.
