Flax Seed Crackers

Raw and fermented flax seed crackers are probiotic, high in fiber and healthy fats

Flax seed crackers are gluten-free, paleo, keto raw, vegan… and incredibly delicious! They’re easy to make and will last for several months, making them a healthy go-to snack. See the sections above for 6 different flavour options and advice on making probiotic crackers.




  • 1 1/4 cup flax seeds
  • 2 tbsp chia seeds
  • 1/2 cup ground flax
  • 1/2 cup sunflower seeds
  • 2 cups of water

Remaining Ingredients

  • 1 tbsp soy sauce
  • 1 tsp salt
  • Other flavours (see above for six different options)


  1. Mix the seeds and water together, and allow to soak for at least 1 hour. The flax and chia will turn into a gooey mass that forms the base for the crackers.
  2. Stir in the remaining ingredients along with any additional flavours. See the section above for some popular flavour combinations.
  3. Line two cookie sheets with parchment paper (wax paper won’t work) or a silicon baking sheet (affiliate link). Spread the mass of seeds as thinly as possible across the two cookie sheets. See notes for more details about how to prevent sticking.
  4. Bake at 250 for around 1 hour. At this point, they should have set enough to be able to be removed from the baking sheet. Peel the crackers off the baking sheet and turn them over so the undersides can cook. If you want perfectly square crackers, cut them at this point before returning them to the baking sheet.
  5. Then turn off the oven and leave the crackers in the warmed oven to set until firm. If they aren’t fully dried out after 30 minutes, then you may need to continue baking for a bit longer. 
  6. Break the crackers up and store them in an air-tight container. They will last for several months in a dry cupboard.


  • To make raw crackers spread the seeds thinly across several parchment-lined dehydrator trays. Dehydrate at 46 C / 115F until fully dry. It may take 12-24 hours depending on your dehydrator.
  • You can also make probiotic crackers! See the section above for more details.
  • The crackers are very sticky and can seize to certain types of baking paper. I use parchment paper that is silicon coated. Alternatively, you could grease the baking paper with coconut oil prior to spreading out the seeds.
