Wash the head of kale thoroughly.
Remove hard stems and lay out individual leaves on kitchen towel to dry.
Work in two batches.
Place half of the leaves in a large bowl and drizzle 1/2 tablespoon of olive oil (don’t use too much oil as this will make the chips greasy).
Sprinkle with sea salt and crushed red chilies. Repeat for second batch.
Spread kale leaves in a single layer on a parchment lined baking sheet.
Place in 350° pre-heated oven and bake for 10 minutes.
Watch them to ensure they don’t burn as they’re very thin and crisp up quickly.
Remove from sheet and serve.
Enjoy immediately (I love when they are warm actually) or store in air tight container/plastic bag.
