Keto Granola — Crunchy, Grain-Free & Just 3g Net Carbs
If there’s one thing I really missed when I first moved over to a low carb diet, it was a proper bowl of cereal in the morning. That satisfying crunch, the cheeky handful straight from the jar… shop-bought granola is basically a sugar bomb, though, so it had to go.

This keto granola is my answer to that: a genuinely crunchy, grain free, gluten free breakfast loaded with toasted nuts and seeds and sweetened the keto friendly way.
At around 3g net carbs a serving, it gives me everything I wanted from a bowl of cereal without nudging me out of ketosis.
I make a big batch most weeks and keep a jar on the worktop — it never seems to last long in our house.
Why you’ll love this keto granola
It’s properly crunchy. Not soft, not chewy — proper jaw-cracking crunch that holds up even after a few minutes in cold almond milk. Grain free and gluten free. No oats, no wheat, nothing that doesn’t belong on a ketogenic diet. Just 3g net carbs per serving, so it slots neatly into your daily macros.
One batch lasts the week (and freezes beautifully), which makes it a brilliant low carb meal-prep job. Genuinely filling. The nuts, seeds and fibre keep me going right through to lunch.
Endlessly adaptable. Once you’ve got the method down, you can swap the nuts and spices to suit your taste.
What makes it keto (the quick version)
Traditional granola is built on oats and honey, which is exactly why it’s off the menu on a keto diet. This version throws all of that out and leans on nuts and seeds instead — almonds, pecans, sunflower seeds, pumpkin seeds, chia and flax. They’re naturally low carb, high in healthy fats and fibre, and they crisp up a treat. The clever bit is the coating: toasted sesame seeds blitzed with a golden keto sweetener, which caramelises around everything as it bakes and brings that toasty, almost-toffee depth you’d normally get from brown sugar. A whisked egg white binds it all into the big clusters everyone fights over. No grains, no sugar, no compromise — just one of those low carb recipes that genuinely earns its place in the cupboard.
A quick word on the nuts and seeds
Every one of these is pulling its weight. Almonds bring healthy fats, fibre, vitamin E and magnesium. Pecans are rich in monounsaturated fats and antioxidants. Sunflower and pumpkin seeds are little mineral powerhouses — think magnesium, zinc and selenium. And chia and flax are where a lot of the fibre and omega-3s come from, which is handy on keto where fibre can sometimes be in short supply. So it tastes like a treat, but it’s quietly doing you a world of good.
How to make keto granola
Don’t be put off by the number of steps — it’s mostly hands-off oven time. Here’s how it goes:
- Toast first. Give the nuts and seeds a light toast in a dry pan (or 10 minutes in the oven). It only takes a few minutes and it makes a real difference to the flavour, so don’t skip it.
- Make the sesame coating. Toast the sesame seeds until just golden, then blitz them with the golden sweetener and cinnamon until you’ve got a fragrant, sandy powder.
- Coat the mix. Tip the powdered coating over the nuts and seeds and toss until everything’s evenly covered.
- Bind it. Whisk the egg whites to soft peaks and fold them through gently — this is what gives you clusters rather than loose bits.
- Bake low and slow. Spread it over a lined tray, scatter on a little pink salt, and bake at a low temperature until set and golden, checking now and then.
- Cool completely. This part is non-negotiable — granola crisps up as it cools, so it’ll feel soft straight from the oven and turn shatteringly crunchy once it’s cold.
- My tips for the crunchiest keto granola
- Keep the oven low. A gentle heat is what stops the nuts catching while the coating sets. Resist the urge to crank it up.
- Don’t stir too much while it bakes. A quick check is fine, but leaving it mostly alone is how you get those big clusters.
- Let it cool fully on the tray. I know it’s tempting, but it won’t reach full crunch until it’s completely cold — and depending on your sweetener, sometimes not until the next morning.
- Press it down before baking if you love clusters. A light press helps everything bake together into bigger chunks.
- Store it properly. An airtight jar keeps it crisp on the counter for about a week, and longer in the fridge or freezer.
Substitutions and swaps
Nuts: not a pecan fan? Walnuts, hazelnuts, macadamias or flaked almonds all work. Just keep the overall weight roughly the same so the coating still covers everything.
Sweetener: I use a golden erythritol and monk fruit blend because it mimics brown sugar and crisps up well. A plain granulated keto sweetener is fine too — just expect a slightly lighter flavour. For anything sticky or fridge-bound I’d reach for allulose, but for crunch this blend is spot on.
No food processor? Use milled flax (known as Linseed in some countries like The UK) and a fine sweetener, and simply stir the toasted sesame seeds through whole. You’ll lose a touch of the caramel coating but it’s still lovely.
Coconut: a handful of unsweetened flaked or desiccated coconut is a gorgeous low carb friendly addition — stir it in with the nuts.
Egg free: a couple of tablespoons of aquafaba whisked to peaks can stand in for the egg whites if you need it.
A note on molasses: you’ll see a lot of granola recipes add a spoon of blackstrap molasses for a brown-sugar kick. I leave it out — molasses is essentially sugar and it knocks the recipe out of keto, so I get my depth from a golden sweetener and a good toasting instead. That keeps this a truly sugar free granola.
How to serve
My go-to is a bowl with ice-cold almond milk and a spoonful of full-fat Greek yoghurt. A few fresh raspberries or blackberries scattered over the top are lovely too — they’re the most keto friendly fruits going, so a small handful won’t tip your carbs. It’s also brilliant eaten dry by the handful as a low carb snack, or sprinkled over yoghurt for a quick keto breakfast.
Keto Granola
Ingredients
For the granola
- 110 g almonds lightly toasted
- 90 g pecans lightly toasted
- 70 g sunflower seeds lightly toasted
- 65 g pumpkin seeds lightly toasted
- 100 g chia seeds
- 60 g flax seeds
- 55 g sesame seeds lightly toasted
- 7 –8 tablespoons golden erythritol and monk fruit blend
- ¾ teaspoon ground cinnamon
- 2 large egg whites
- Pink Himalayan salt to taste
To serve (optional)
- Ice-cold almond milk
- Full-fat Greek yoghurt
- Fresh raspberries or blackberries
Instructions
- Preheat the oven to 120°C (fan 100°C / 250°F) and line a large rimmed baking tray with baking paper or a silicone mat.
- Lightly toast the almonds, pecans, sunflower seeds and pumpkin seeds in a dry pan over a medium-low heat for a few minutes, until golden and fragrant, then tip into a large bowl with the chia and flax seeds.
- Toast the sesame seeds in the same pan over a medium-low heat for 4–6 minutes, until just golden — watch them closely so they don’t catch and turn bitter.
- Add the toasted sesame seeds, sweetener and cinnamon to a food processor and pulse until you have a fine, fragrant powder.
- Tip the sesame mixture over the nuts and seeds and stir until everything is evenly coated.
- Whisk the egg whites to soft peaks, then fold them gently through the mixture until fully combined.
- Spread the granola over the prepared tray in an even layer, pressing down lightly if you like bigger clusters, and scatter over a little pink Himalayan salt.
- Bake for 45–50 minutes, checking every 15 minutes, until set and golden.
- Leave to cool completely on the tray — it will keep crisping up as it cools (some sweeteners need an overnight rest to reach full crunch).
- Break into chunks and store in an airtight container for up to a week, in the fridge for up to 2 weeks, or in the freezer for up to 2 months.
