Step 1

Preheat the oven to 275F.

Step 2

Remove the stems from the kale leaves using a knife or your hands. Tear each leaf into about 2 inch pieces. The pieces should be roughly the same size but don't need to be exact.

Step 3

Rinse kale leaves to remove any dirt or debris. Dry with a salad spinner or pat dry with clean towels.

Step 4

In a large bowl, toss together the kale pieces and olive oil so that each piece of kale is fully coated in oil.

Step 5

Place kale pieces on a large sheet pan. Sprinkle with nutritional yeast and salt.

Step 6

Spread the kale pieces out so that they aren't overlapping one another. You may need to cook the kale in batches.

Step 7

Cook the kale at 275F on the middle oven rack for 15-20 minutes. Start checking kale at 10 minutes to avoid burning it. The kale is ready when crisp and crackly but not browned. It will firm up a little as it cools.

Step 8

Season with additional nutritional yeast if desired. Kale chips are best enjoyed immediately after cooking them.
