There aren’t a lot of easy-to-make snacks that pack as much of a nutritional punch as kale chips. Unlike some trendy foods, kale truly deserves its healthy halo.

Why does kale get so much credit? Kale is packed with anti-inflammatory and anti-oxidant properties. It's remarkably high in fibre and iron; it's also high in vitamins K and D, and a great source of calcium. To add to this already impressive list, it’s also high in omega-3 and 6, folic acid and Vitamin B6.

Nutritional benefits aside, crispy kale chips are one of my favourite things to make with kale. And — after years of practice — I think I've discovered the perfect way to make them.

The key to perfect kale chips? A slow and low bake. Most kale chip recipes call for a temperature between 350F and 425F. This seems logical, as we normally use a high heat when we want something crispy. However what tends to happen at this temperature is that the thinner parts of the kale become brittle, brown and bitter while the thicker parts are either undercooked or chewy. To get perfectly uniform, crispy kale chips, the key is to bake them for longer, at a lower temperature. Baking kale chips at 300F for 20 to 25 minutes allows the vegetable to slightly dehydrate while it cooks, resulting in a perfectly crispy chip.

The other trick to awesome kale chips is to flavour them up. Once the chips have been rubbed with oil, sprinkle them with anything you like. I like using quinoa flakes, lemon rind, curry powder, paprika, finely grated cheddar or parmesan, pepper or even brown sugar before you bake them. Give them a try:
