Gluten-Free Seed Cracker Ingredients

These gluten free seed crackers come together with a simple mix of whole seeds, water, salt, and seasoning.

• Sunflower seeds: Add crunch and a mild, nutty flavor.
• Pumpkin seeds: Give the crackers extra texture and richness.
• Flaxseeds: Help bind the mixture as they absorb water.
• Chia seeds: Create the gel-like texture that helps hold these flourless seed crackers together.
• Sesame seeds: Add a lightly toasted, savory flavor.
• Boiling water: Hydrates the seeds and helps the mixture thicken before baking.
• Fine salt: Seasons the crackers evenly throughout.
• Everything bagel seasoning: Adds extra savory flavor and crunch on top. I like using a clean brand without unnecessary preservatives or additives.

For a more neutral flavor, you can skip the everything bagel seasoning and finish the crackers with flaky salt instead.

You can also make your own seasoning blend with sesame seeds, poppy seeds, dried minced garlic, dried minced onion, and flaky salt.

How to Make Gluten-Free Seed Crackers: Step by Step

These gluten free seed crackers are simple to make with a few easy steps. The key is spreading the mixture very thin and baking until completely crisp.

Step 1: Line a baking sheet with parchment paper. In a medium bowl, mix the sunflower seeds, pumpkin seeds, flaxseeds, chia seeds, sesame seeds, and fine salt.

Step 2: Pour in the boiling water and stir well. Let the mixture sit for 15 minutes to thicken and gel, stirring once halfway through.

Step 3: While the seed mixture thickens, preheat the oven to 280°F or 130°C fan.

Step 4: Scoop the mixture onto the prepared baking sheet and use an offset spatula to spread it into a very thin rectangle, about 15 x 10 inches. Try to keep the thickness as even as possible so the crackers bake consistently.

Step 5: Sprinkle the everything bagel seasoning evenly over the top. Score the mixture into an 8 x 4 grid so the crackers are easier to separate after baking.

Step 6: Bake for 40 to 45 minutes, until the edges are lightly golden and the crackers feel firm and crisp when gently pressed.

Step 7: Carefully flip the crackers over and return them to the oven for another 15 to 20 minutes. They’re ready when the tops feel dry and the edges begin to curl slightly.

Step 8: Remove from the oven and let the crackers cool completely on the baking sheet. Once cooled, snap or cut along the score lines into individual crackers.

Recipe Tips & Tricks

• Use an offset spatula: It makes it much easier to spread the seed mixture into a thin, even layer without tearing the parchment.
• Watch the edges closely: The outer crackers may crisp faster than the center, so check for dryness and firmness rather than relying on color alone.
• Let them cool completely: Seed crackers firm up more as they cool, so give them time before deciding whether they need extra baking.
• Re-crisp if needed: If any crackers still feel soft or flexible after cooling, bake them again at 300°F for 5 to 10 minutes in a single layer.
• Store only when fully dry: Any lingering moisture can make the crackers lose their crunch, so make sure they are completely crisp before transferring them to an airtight container.
• Make the seasoning your own: Try flaky salt, dried herbs, garlic, onion, or a homemade everything bagel blend for an easy flavor change.

⭐ Confidence Tip: If some crackers crisp up before others, remove the finished pieces first and let the softer ones keep baking. This helps prevent the edges from getting too dark while the center catches up.

Storage & Reheating

• Storage: Once the crackers are completely cool and fully crisp, store them in an airtight container at room temperature for up to 2 weeks. Make sure there is no lingering moisture before storing, since that can soften the crackers.
• Reheating: These crackers do not need reheating, but you can easily re-crisp them if needed. Place them in a single layer on a lined baking sheet and bake at 300°F for 5 to 10 minutes, then let them cool completely.
• Freezing: I do not recommend freezing these seed crackers. They keep well at room temperature, and freezing can introduce moisture that may affect their crisp texture.

Additions & Substitutions

These gluten free seed crackers are easy to customize with different seasonings and seed combinations, so you can change the flavor depending on what you have on hand.

Additions

• Rosemary + garlic: Add finely chopped fresh rosemary and a little garlic powder for a savory, herb-forward variation.
• Smoky spice: Mix in smoked paprika, cumin, or a pinch of chili flakes for a warmer, slightly smoky flavor.
• Za’atar seasoning: Swap the everything bagel topping for za’atar for an earthy, herby version that pairs especially well with hummus.
• Fresh herbs: Add finely chopped thyme or oregano to the seed mixture for another simple flavor variation.
• Black pepper + flaky salt: Finish the top with cracked black pepper and flaky salt for a simple, savory version.

Substitutions

• Sunflower seeds: You can replace them with additional pumpkin seeds for a slightly richer, crunchier cracker.
• Pumpkin seeds: Swap with sunflower seeds if that is what you have available. Keep the overall amount of larger seeds similar so the texture stays balanced.
• Sesame seeds: Hemp hearts can be used instead for a mild, nutty variation, although the finished crackers may be slightly less crisp.
• Everything bagel seasoning: Use za’atar, dried herbs, garlic and onion seasoning, or simply flaky salt depending on the flavor you want.
• Seasoning salt: If your seasoning blend already contains plenty of salt, slightly reduce the fine salt in the cracker mixture to avoid over-seasoning.
