Crispy Seed Crackers Recipe

Light and crispy, this seed crackers recipe is healthy and delicious. It’s naturally gluten-free and nut-free. The flavors can be added and changed to suit your tastes.

This seed crackers recipe uses only seeds as the base, with no added flour. The addition of chia seeds and flax seeds works as a binder when combined with water. Sesame seeds, pumpkin seeds, and sunflower seeds bring texture and taste.

A little garlic powder and sea salt are added too and that’s it! Such an easy homemade crackers recipe. Perfect for the lunchbox or to serve with a cheese board.

The seeds

Some of the seeds in these crispy crackers can be changed to suit your tastes, but chia seeds and flax seeds are important because they act as the gelling agent in the mixture.

This healthy recipe uses lots of seeds that all come with their own health benefits.

  • Chia seeds – They are a great source of fiber and powerful antioxidants such as quercetin. Chia seeds when mixed with water, swell up and create a jelly-like texture (like in this low-sugar blackberry jam!) This thickens the cracker batter and helps spread it into the tray.
  • Ground flaxseed – Like chia seeds, flaxseed swells and gels up to thicken the mixture. Ground flaxseed meal is easier to digest than whole flax seeds. Flaxseeds are high in omega 3 and other nutrients.
  • Pumpkin seeds – Also known as pepitas. These add pretty green pops of color to the crackers and bring healthy fats and lots of vitamins and minerals such as iron, zinc, manganese, phosphorous, and magnesium.
  • Sunflower seeds – These help to bring texture and more vitamins and minerals.
  • Sesame seeds – A combination of white sesame seeds and black sesame seeds adds great color contrast, but also different flavors and vitamins.

Method

In a large bowl, combine all the seeds, garlic powder, and salt and stir. Pour over warm water and stir it until all the seeds are wet through.

Leave this mixture to stand for 15 minutes while the seeds soak up the water. After this time period, the mixture will have thickened into a thick and jelly-like mixture.

Line a baking sheet with a sheet of parchment paper. Scoop the seed mixture on the parchment paper and use an offset or rubber spatula to smooth it out into a thin rectangle measuring around 10×12 inches (25x30cm.) You want the mixture to be spread thin, but not too thin or the crackers will be too brittle.

Bake the crackers at 175°C/350°F for around 25 minutes until the tops of the crackers have dried out. Remove the baking tray from the oven and use a sharp knife, pizza cutter, or bench scraper to cut the crackers into squares. Don’t worry too much about straight lines, these crackers suit a rustic look.

Place the tray back in the oven and bake for a further 20-25 minutes until the crackers are completely dry. Ensure the crackers don’t become too brown or burn or else they will be bitter.

Check them regularly, the outer crackers will be baked much sooner and can be removed first. The middle crackers will take the longest to cook. You can flip the middle crackers upside down if you like so the bottoms have a chance to dry out too. The baking time will change depending on your own and the thickness of the crackers.

Ensure the crackers are completely dried out, then let the cool on a wire rack. They will become more crispy as they cool.

Serving and storing

Serve these multi-seed crackers with your favorite dip or cheese, or quince jelly or paste.

The baked crackers can be stored in an airtight container once they have cooled to room temperature. Ensure each cracker is completely dry and crisp before storing, or else all the crackers in the container will soften.

Additions and substitutions

You can swap out or add to some of the seeds if you want. Next time try adding

  • Poppy seeds
  • Hemp seeds
  • Fennel, caraway, or cumin seeds (only a small bit will be needed, these will bring a lot of flavors.)
  • Add a little onion powder for extra flavor, or bagel seasoning
  • Dried herbs can add flavor too. Add them sparingly

  1. I’d love to try making these in my new dehydrator. Any idea on what time/temp might work for a longer, slower cook? Thanks!
