Homemade seed crackers piled up on a white plate.

Crackers are such a fun snack and are surprisingly easy to make. My recipe offers the perfect crunch with just the right touch of salt and other flavors.

This recipe is also very allergy-friendly considering it’s nut-free, grain-free, gluten-free, dairy-free, and vegan.

I’ve made these crunchy seed crackers countless times and my husband is always asking for a new batch. We love to eat these healthy crackers plain or serve them with cashew hummus, cucumber salsa, or oil-free chickpea hummus.

Recipe Substitutes

  • You can use whole or ground flaxseeds, but whole flax gives better crunch.
  • Do not remove chia seeds entirely, or the crackers may crumble.
  • If whole seeds are difficult to digest, lightly pulsing the mixture in a food processor can help while still keeping texture.

Tips to Make Seed Crackers Crispy (Not Soggy)

One of the most common issues with homemade seed crackers is ending up with crackers that are chewy or soft instead of crisp.

Here’s how to get perfectly crunchy crackers every time:

  • Spread the mixture evenly: Aim for about ¼-inch thickness. If the mixture is too thick, the crackers won’t dry out properly.
  • Let the mixture rest: After adding water, allow the chia seeds to gel fully before spreading. This helps the crackers bake evenly.
  • Bake low and slow: A lower temperature allows moisture to evaporate without burning the seeds.
  • Cool completely before breaking: The crackers continue to firm up as they cool. If they feel soft when hot, that’s normal.
  • If needed, re-bake: If the crackers aren’t fully crisp after cooling, return them to the oven for 10–15 minutes.

Humidity note:
If you live in a humid climate, crackers may need slightly longer baking time or a brief re-bake the next day to restore crispness.

Storage Tips

Store fully cooled crackers in an airtight container at room temperature for up to 7 days. If they lose crispness, place them back in the oven for a few minutes to refresh.

Recipe FAQs

Can I use different seeds to make homemade crackers?

Definitely use what you have to create the full amount needed in the recipe. You want to have a variety and you also want to make sure and still use at least 1/4 cup of chia seeds. These are your vegan “glue” that holds everything together, much like an egg would in other recipes.

Is this recipe allergen-friendly?

There is no dairy, gluten, or nuts in this recipe. The only thing to keep in mind is any cross-contamination issues in the seeds if you have a nut allergy and are very sensitive.

Can I make these seed crackers in an air fryer?

Yes, but results vary by model. Spread the mixture thinly on parchment, air fry at a low temperature, and check frequently to avoid burning.

Why did my seed crackers turn out soggy?

This usually means the crackers were too thick, underbaked, or not fully cooled. Let them cool completely, then re-bake if needed.

Can I freeze homemade seed crackers?

Yes. Once fully cooled, freeze them in an airtight container. Let them thaw at room temperature and re-crisp in the oven if needed.

Should I use raw or roasted seeds?

Raw seeds work best. They toast naturally during baking, which prevents bitterness and uneven browning.

Here is a homemade, flavorful recipe for Seed Crackers. This vegan and gluten-free recipe has no preservatives and is full of fiber and nutrition. Skip store-bought crackers and make your own!

  • Total Time: 120 minutes
  • Yield: 10 servings 1x

Ingredients

Units Scale
  • 1/2 cup raw hulled sunflower seeds
  • 1/4 cup raw hulled pumpkin seeds
  • 1/4 cup chia seeds
  • 1/4 cup flax seeds
  • 1/2 teaspoon sea salt
  • 1 teaspoon dried garlic
  • 3/4 cup water
  • Nonstick cooking spray

Instructions

  1. In a large mixing bowl, combine the sunflower seeds, pumpkin seeds, chia seeds, flax seeds, salt, garlic, and water. Stir to combine. Let the mixture sit for at least 20 minutes to thicken before moving onto the next step.
  2. Preheat your oven to 300°F. Line a baking sheet with parchment paper. Spray the top of the parchment paper lightly with nonstick cooking spray.
  3. Stir the seed mixture and transfer it onto the baking sheet. Use a spatula to smooth the surface of the mixture so it is about ¼-inch in height. Then, use a knife to score cracker shapes into the mixture.
  4. Place the baking sheet in the oven for 50-60 minutes, or until the tops of the crackers start to turn a golden brown.
  5. Remove the baking sheet from the oven.
  6. Lay the parchment paper with the crackers on a cooling rack for 20-30 minutes to let the crackers cool completely.
  7. Then, once the crackers are cool, remove them from the parchment paper and use your hands to break the crackers into pieces.
  8. Enjoy immediately, or place the crackers in an airtight container and store for up to 7 days.

Notes

  1. Feel free to adjust the types of seeds you use in this recipe. But, use at least ¼ cup of chia seeds to help the mixture stick together.
  2. You can use either whole or ground flax seeds in this recipe, but I recommend using whole flax seeds to get more texture in the crackers.
