Thinly slice 1 block extra firm tofu (about ⅛ to ¼ inch thickness).
Add ⅓ cup beet juice and 3 tablespoons soy sauce to an airtight container.
Break 2 bay leaves into pieces, then add them to the container.
Add ½ teaspoon ground mustard, ½ teaspoon ground coriander, ¼ teaspoon ground allspice, ¼ teaspoon ground cloves, and ¼ teaspoon black pepper to the container, then mix well.
Add the thinly sliced tofu to the container.
Close the lid of the container tightly, then gently turn it upside down a few times to distribute the marinade.
Place the container in the freezer for at least 8 hours or until frozen.
Transfer the container to the fridge for 24 hours or until fully thawed.
Preheat the oven to 350 degrees Fahrenheit.
Place the marinated tofu slices in an even layer on a sheet pan lined with parchment paper.
Bake for 20 minutes.
