How To Make Multiseed Low-Carb Crackers

Preheat the Oven. Set your oven to 180°C/ 355°F for a fan-assisted oven, or 200°C/ 400°F for a conventional oven.

Mix the Seeds and Seasoning. In a large mixing bowl, combine sunflower seeds, sesame seeds, flaxseeds, chia seeds, pumpkin seeds, and poppy seeds. Add Seasoning. Add in onion or garlic powder, black pepper, and salt. Optionally, include any additional spices like cumin or smoked paprika.

Partially Grind Seeds. Take about half of the seed mixture and place it in a food processor. Process until finely ground. Return the ground seeds to the bowl with the rest of the ingredients and mix well.

Add Water. Pour in 1 cup of water, stir, and let the mixture sit for 5-10 minutes.

Shape the Dough. Prepare Baking Sheet. Line a 10 x 14-inch baking sheet with a silicone mat or heavy-duty parchment paper. Use a rubber spatula to spread the dough evenly on the prepared sheet, aiming for a thickness of about 1/8 inch.

Pre-Cut the Crackers. Using a pizza cutter, slice the dough into 24 pieces, forming 6 rows and 4 columns.

Bake the Crackers. Place in the preheated oven and bake for about 40 minutes. Rotate the tray halfway through.

Final Cuts and Cooling. After baking, go over the pre-cut lines to separate the crackers. Allow them to cool and crisp up for 20-30 minutes.

Tips for the Best Low-Carb Crackers

  • Freshness Counts: Use fresh seeds or seeds stored properly in the fridge or freezer to prevent rancidity. Seeds contain oils that can spoil, affecting both the health benefits and taste. Fresh seeds ensure your crackers will have the best flavor and nutritional value. Rancid seeds can have an unpleasant fishy or plastic-like smell, so always do a smell and taste test before using.
  • Balanced Moisture: Ensure your seed mixture has just enough water to bind together without being soggy. The dough should be sticky but not wet, which will help achieve a crisp texture once baked.
  • Even Thickness: When spreading the cracker dough, aim for a consistent thickness to ensure even baking. Uneven thickness can lead to some crackers burning while others are not yet crisp.
  • Slow and Low Baking: Bake your crackers at a low temperature to dehydrate them slowly, which helps achieve a perfect crunch without burning.
  • Seed Variety: Use a mix of seeds for a complex flavor and texture. Each type of seed brings a different nutrient profile and a variety of crunch.
  • Proper Storage: Store your cooled crackers in an airtight container to keep them crisp. If they soften, you can re-crisp them in the oven for a few minutes before serving.

Storage Instructions

How long will these crackers last?

Keep any remaining low-carb crackers in an airtight container at room temperature for up to two weeks.

Can I freeze keto crackers?

Yes, you can store them in the freezer for up to 6 months. Use a container rather than bag to avoid breaking them.

How To Serve These Keto Crackers

These crackers are delicious on their own or with any dips. Guacamole, hummus, or tzatziki are excellent choices!
