My neighbour at the Saturday markets on Eveleigh Street in Redfern sells three bunches of Tuscan kale for five dollars right now, and I have been quietly buying two of those bunches each week just to make this. Not to be virtuous about it. Honestly, just because they come out of the oven smelling extraordinary and I can’t stop eating them standing at the bench.
Why kale chips with sea salt are worth the effort
I’ll be upfront: kale chips are not a dump-and-forget recipe. The margin between perfectly crisp and quietly bitter is narrower than most food writers admit, and I’ve produced more than a few trays of sad, leathery leaves in my time. But once you understand what’s actually happening in the oven, the results are consistent and genuinely satisfying.
The principle is simple: you’re driving moisture out of the leaf at a low enough temperature that the thin edges dehydrate and crisp before the thicker centre burns. Curly kale works, but Tuscan kale (also called cavolo nero or lacinato kale) gives you a flatter leaf that dries more evenly. What I love about this recipe is how little oil you actually need — a light coat, barely glistening, is exactly right. More oil and you steam rather than crisp.
From a nutrition standpoint, kale holds up reasonably well to low-heat roasting. The Australian Dietary Guidelines put dark leafy greens in the same category as other non-starchy vegetables and encourage eating more of them across the day — which is one genuine reason to have a snack like this in your lunchbox rotation rather than something processed.
Ingredients
- 1 large bunch Tuscan (cavolo nero) kale, approximately 300 g
- 1 tablespoon extra-virgin olive oil
- ¼ teaspoon fine sea salt, plus extra flaked sea salt to finish
- ¼ teaspoon garlic powder (optional)
Serves 2 as a snack, or makes one generous lunchbox portion. Recipe scales easily — just don’t crowd the trays.
Method
- Preheat your oven to 150°C fan-forced (or 170°C conventional). Line two large baking trays with baking paper.
- Wash the kale well and dry it thoroughly. This is the step people rush and then regret. Any surface moisture will steam the leaves instead of crisping them. I spread mine out on a clean tea towel and pat firmly, then let it air for ten minutes while the oven heats.
- Strip the leaves from the central stems by holding the stem at the base and pulling upward in one firm motion. Discard the stems or save them for a broth. Tear the leaves into pieces roughly 6–8 cm — they shrink by about a third, so bigger than you think is right.
- Place the leaves in a large bowl. Drizzle over the olive oil and the fine sea salt. Now massage gently with your hands for about a minute, working the oil into every surface. The leaves should glisten but not feel slick. If you can see pooled oil at the bottom of the bowl, you’ve added too much.
- Spread the leaves in a single layer across both trays. They should not overlap. This is non-negotiable — overlapping leaves trap steam and you get rubbery patches.
- Bake for 12 minutes, then rotate the trays and check. You’re looking for edges that are crisp and just starting to turn a deeper, slightly translucent green-brown. The centre of each piece should feel dry to a gentle touch. If they need more time, return for 3–5 minutes and check again. Total time is usually 15–18 minutes.
- Remove from the oven and scatter immediately with flaked sea salt. Leave on the tray to cool for five minutes — they firm up further as they cool.
The smell when it hits the temperature
Around the twelve-minute mark, the oven starts doing something that smells a bit like toasted nori and a bit like roasted nuts. That’s the Maillard reaction working on the leaf proteins at low heat, and it’s your signal that you’re close. If it tips toward anything acrid or sulphurous, pull the tray immediately — the outer leaves are telling you they’ve gone a minute too far.
I grow a few pots of chilli on my Sydney balcony (currently a small Thai variety that is frankly out of control), and a pinch of dried chilli flakes added with the sea salt at the end is the version I make most often for myself. The heat is entirely optional but the combination with the salt and the slight bitterness of the kale is very good.
A note on storage — and an honest admission
Kale chips are genuinely best eaten within two hours of coming out of the oven. I know recipe writers often say this as a formality, but here I mean it. By the next day, even in an airtight container, they’ve absorbed enough ambient humidity to go soft at the edges. Not inedible, but no longer that pure crisp snap that makes them worth making. If you’re packing them for a lunchbox, do it the morning of, not the night before, and use a container that isn’t airtight so air can circulate slightly.
The Better Health Channel recommends aiming for five serves of vegetables daily, and whilst a snack-sized portion of kale chips won’t carry the full load of a serve, it’s a genuinely useful top-up and a real alternative to crackers or chips from a packet.
If you’re building out a lunchbox alongside these, my Raw Chia Energy Bars hold up far better overnight and travel well — good for kids’ boxes where you need something that can be made the evening before without compromise.
Variations I’d actually recommend
A light dusting of nutritional yeast before baking gives you a savoury, slightly cheesy quality that works well for people who find plain kale chips a bit austere. Use about one teaspoon for a full batch and massage it in with the oil. It catches more quickly than the plain version, so start checking at ten minutes.
Smoked paprika is another one that earns its place — half a teaspoon with the garlic powder gives a warmth that reads as almost smoky and meaty. I made these for a small gathering at a friend’s place near Glebe recently and they went faster than anything else on the table. People who said they didn’t eat kale ate them.
What I would not bother with: any liquid additions (tamari, lemon juice, soy sauce) before baking. I’ve seen this suggested in various places and have tried it enough times to be confident the moisture content makes crisping reliably very difficult unless you have a dehydrator rather than a domestic oven. Save any liquid seasoning for a drizzle over something like the shaved fennel and orange salad instead, where the texture isn’t at stake.
Where kale chips fit in a snack rotation
I think of these alongside the Golden Door Breakfast Balls as the kind of snack that takes a little bit of intent but earns it. Not a weeknight-after-work situation when you want something immediately, but a Sunday-afternoon batch that sets you up for the week’s lunchboxes and afternoon moments.
For anyone leaning on snacks to keep energy steady across the day rather than relying on something sugary, these fit well. The fibre in kale contributes to that slower, more even effect — and if you want to understand more about why that matters physiologically, the piece on why fibre matters more than most of us think covers the mechanism clearly.
That’s the whole recipe. Make it on a quiet morning when you’re not watching the clock, dry the leaves properly, and don’t crowd the trays. Everything else is forgiving.
