Divide kale between 2 large baking sheets (or more if increasing batch size) and spread into an even layer, making sure the pieces aren't overlapping to ensure crispiness. You may need to bake them in two batches depending on size of baking sheets.
Sprinkle the kale with remaining 1-2 Tbsp (3-6 g // amount as original recipe is written // adjust if altering batch size) nutritional yeast for extra flavor and bake for 15 minutes. Then remove from oven and toss/flip kale to ensure even baking.
