Why you’ll love these 5 seed crackers

  • Gluten-free and nut-free snack option.
  • Vegan and keto-friendly recipe.
  • The crackers store well.


  • Chia seeds – You can use white, black, or a mix of white and black chia seeds for this recipe. As the water is added to the dry ingredients, the chia seeds will gel up quickly within minutes, creating a uniform mixture. Don’t let the seeds soak for too long or the mixture will be too wet and soggy.
  • Sunflower & pumpkin seeds – Use natural, unroasted seeds.
  • Sesame seeds – I recommend using white sesame seeds for extra color in the crackers but you can use black sesame as well.
  • Flax seeds / linseeds – Use whole flax / linseeds for this recipe, not ground ones.
  • Herbs & spices – I love adding dried thyme and salt to my crispy chia seed crackers but you can certainly use whatever spices and flavors you like. Oregano, basil, rosemary, cumin, black pepper, or chili flakes are all great options.

Tips on how to make five seed crackers

  • You can substitute the seeds with other seeds as long as the overall seed-to-water ratio remains the same. Do not reduce the amount of chia seeds in the recipe as they are required to hold the seeds together.
  • Make sure you spread the mixture thinly onto the baking tray – about 5 mm – for the flax and chia seed crackers to turn out nice and crispy. Otherwise, they can get chewy and soggy.
  • If your oven has hotspots, turn the baking tray half-way through baking or cover it with another layer of baking paper if necessary.
  • Let the keto seed crackers fully cool before storing them in an airtight container. Any moisture will make them soggy and will impact the shelf-life.


These crispy seed crackers are delicious on their own but are an excellent companion for your favorite dip such as this smoked tuna dip, cheese, or pâté. Add them to an antipasto or cheese platter for extra flavor and crunch. Being nut-free, they’re also an excellent addition to kids’ lunchboxes.


How long do seed crackers stay fresh?

Once fully cooled, store the seed crackers in an airtight container in a cool and dark place to preserve their crunch. They will stay fresh for about 4 weeks.

Is it cheaper to make your own seed crackers?

It depends on the type of ingredients and crackers you buy but generally, it is significantly cheaper to make seed crackers yourself.
