Preheat the oven to 420 degrees F. Line a sheet pan with parchment paper (optional).
Prep the tofu: Drain off liquid from the tofu. Pat dry with a clean dishtowel or paper towel. Slice tofu into one-inch triangles or squares.
In a medium bowl, toss the tofu pieces with sambal oelek, soy sauce, and oil.
Spread out the pieces of tofu on a parchment paper-lined baking sheet, careful not to overlap any tofu pieces.
Bake at 420F for 15-20 minutes, until the tofu appears golden. It shouldn't be 100% done. Remove from the oven.
Transfer tofu back to the bowl. Toss with ⅓ cup BBQ sauce, adding more as needed to evenly coat each piece of tofu.
Transfer back to the baking sheet to bake for an additional 5-10 minutes. Bake for 5 minutes for golden, crisp tofu. Bake for 10 minutes for almost blackened tofu. Remove from the oven and enjoy!
