I know. Crackers are not sexy. But they are a brilliant snack to have around the house. They can stop you reaching for chocolate or sweets when you're feeling peckish. They are filling, great with butter, cheese, cold cuts and dips (think guacamole, cauliflower hummus or tzatziki) and really easy to make!
With grains out of the equation on a low carb diet, Ryvita and Co are not an option. And while store bought keto crackers do exist, they are pricey. That's why I prefer to make my own.
I have a few cracker recipes on the blog already. There's these Low Carb Crackers, which are made with almond flour, and Cheese Thyme Keto Crackers with coconut flour. I even have a cracker recipe made with a mix of sesame flour and flaxseed - my Easy Sesame Flaxseed Crackers.
These flax seed crackers are super simple and fuss free. They stay crispy and and even better, they are super healthy!
Health benefits of flaxseed
Flax is loaded with nutrients. It's high in fibre, protein and omega-3 fatty acids. On top of that, it's a rich source of vitamins and minerals. Read more about the benefits of flaxseed here.
Ingredients for flax crackers
Milled Flaxseed - Make sure you use milled or ground flaxseed, not whole. You can use both brown or golden flaxseed. I think golden tastes and looks the nicest - it tastes milder than the brown flax.
I like to buy whole flax and grind the seeds myself for the best freshness. If you buy ready milled flax, be sure to store open packs in the freezer because milled flax oxidises.
Water - â…“ cup or 80 ml. I made the first version with 120 ml, but found that the crackers were not as crispy as I wanted.
Olive oil - Not 100% essential for the recipe, but adds lovely flavour. I used a light, mild olive oil.
Salt & pepper - Because everything tastes better with salt and pepper!
How to make flaxseed crackers
Mix all the ingredients together in a bowl with a spoon. Allow to stand for a couple of minutes so the flax can absorb the liquid. Roll into a ball. If the dough feels a touch sticky, dust in a little more flax and on your hands and knead.
Roll the dough between 2 sheets of parchment paper to approximately 3mm thickness. Remove the top sheet and fold over edges for form a rectangle. Place the top sheet back on top and re-roll. I did this twice to get a good rectangle shape.
Cut into squares, about 4-5cm, using a pizza cutter. Re-roll the offcuts, if you have any.
Bake on the bottom parchment paper for 22 - 25 minutes or until golden. Allow to cool and cut fully.
Oven timings for keto crackers
The baking time of your flaxseed crackers will depend on how thick or thin you have rolled them out. Thicker crackers will need longer than thin ones.
Also, the crackers on the outside edges of the baking sheet will brown quicker than the ones in the centre and crackers at the back of the oven may turn golden sooner than the ones at the front.
You can rotate the baking sheet during baking to even out the browning. Also, if. some of the crackers are browned completely but others aren't, simply remove the ones that are done and give the rest a little more oven time.
Recipe Variations
I've given you the base recipe for flax crackers. If you want to change things up, here are some optional flavourings you can try:
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 2 teaspoon dried herbs like rosemary, oregano or thyme
- â…“ cup grated parmesan
- 1 teaspoon cumin
- 1 teaspoon za'atar - a fragrant Middle Eastern spice mix
- ¼ teaspoon cayenne - for a spicy kick
- poppy seeds or sesame seeds
- chopped olives or sun-dried tomatoes (chop very small and use sparingly)
How to store flaxseed crackers
I keep my crackers in an airtight tin on the counter. This way, they stay crispy. Mine have never lasted longer than one week, but these should be good for two weeks or longer.

I put bagel seasoning in the mix but these didnt stay crispy the next day.
Katrin Nürnberger
There are a few reasons why crackers go soft. First, they were not crispy from the start. This happens when you roll them out too thick and / or did not bake them long enough for all liquid to evaporate. Second, they were stored in a place where they attracted moisture. You need to store crackers in an airtight container without anything else inside that is moist (such as bread). If you do this, crackers actually stay crispy for many weeks. Hope this helps!
Kathryn Peavy
Can’t wait to bake the bread
Gina Cooper
What is the shelf life, and time frame for storing and eating these crackers? Ty.
Katrin Nürnberger
From my personal experience, they last a long time. At least 2 weeks and probably more, if you keep them in an airtight container.
Joey gill
How many grams of sesame seeds would you recommend putting into the recipe?
Katrin Nürnberger
I would use 2-4 tablespoons.
Michele
I added cumin and nutritional yeast
Yummmm
And Doubling the recipe is essential!! They are amazing and never last more than two days
Perfect to take on trips
The outer edges baked quicker so I took those out first and let the middle continue baking
Thank you for making my new healthy menus so delicious

Can I add some whole flax - I bought a commercial flaxseed keto cracker on holiday and it has quite a few whole flaxseeds in it but must be held together with some ground flax. They also have apple cider viegar in them - any idea what this is for?
Katrin Nürnberger
Hi Carolyn, you can definitely add whole flax. Apple cider vinegar can be used as a raising agent, so maybe that's the reason it's in there. It also has health properties and actually tastes good!
Freda da costa
Hi my name is Freda! I also made these crackers today. I am pleased to say I think they came out fine! My daughter said they were a bit bland so I see there are a lot more spices I can add will try to make them again tomorrow. I am going to make the egg free bread so looking forward to that.
Katrin Nürnberger
Glad you like the recipe!
Elizabeth Vaughan
I added a teaspoon of poppy seeds they turned out absolutely lovely (I tested one when no one was looking as you do) lovely for supper tonight with cheese. Thank you Katrin
Katrin Nürnberger
Testing is half the fun of cooking! Glad you like the crackers.
Heidi
Excellent recipe. So simple and deliciously crispy.
Katrin Nürnberger
Glad you liked the crackers!
jo
My fav crackers ever! Go with everything.
Jean Finch
Can I add 1/2 cup hemp seeds instead of 1/2 of the flax?
Katrin Nürnberger
Yes, as long as you still use flax it should work.
