These chia and flax seed crackers offer a wholesome, crunchy snack you can feel great about making and sharing. Packed with nutritious seeds and fragrant spices, they crisp up beautifully in the oven. I reach for this recipe any time I want something light, satisfying, and homemade to partner with dips or top with cheese.
My family asks for these on road trips because they travel so well. The first time I pulled a batch out during a movie night, they were gone before the opening credits ended.
Ingredients
- Chia seeds: Give the crackers their signature crunch and binding power. Look for seeds that are uniform in color and free from dampness.
- Flax seeds: Add even more fiber and a gentle nutty flavor. Choose whole golden or brown flax seeds with a glossy appearance.
- Water: Helps activate the chia and flax to create a cohesive dough. Use filtered water for the cleanest flavor.
- Garlic powder: Adds a savory note. Pick pure garlic powder without added fillers.
- Onion powder: Deepens the flavor and rounds out the seasoning. Use a fresh-smelling powder free from clumps.
- Sea salt: Brightens all the flavors. A high quality flaky or fine salt works well.
- Dried thyme: Brings a subtle earthy aroma. Make sure your thyme is still fragrant and green, not brown.
Step-by-Step Instructions
- Prepare the Oven and Sheet:
- Set your oven to 300 degrees Fahrenheit or 150 degrees Celsius. This gentle heat lets the seeds crisp up without scorching. Spread a sheet of parchment on your baking tray and extend it past the edges for easy lifting and cleaning.
- Mix the Seeds:
- Combine chia and flax seeds in a medium bowl. Use a spoon or spatula to mix thoroughly so the two seeds are evenly dispersed.
- Hydrate the Mixture:
- Pour water over the seeds. Stir well. The mix will look watery at first. Let it rest for about fifteen minutes. Stir a few times as the chia absorbs water and a gel-like texture forms. This step is crucial for getting crackers that hold together.
- Season the Dough:
- Once the mixture is thick and gelled, add garlic powder, onion powder, sea salt, and dried thyme. If you like extra seeds, pumpkin or sunflower can be stirred in now. Mix until everything is even so each bite is flavorful.
- Spread and Shape the Crackers:
- Scoop the entire mixture onto the lined baking sheet. Use a spatula or the back of a spoon to spread it out to roughly one eighth inch thick. For the most even crackers, place another parchment sheet on top and roll with a rolling pin until uniformly thin.
- Score for Easy Breaking:
- If you want neat crackers, use a knife or pizza cutter to lightly score the dough into your desired cracker size. This will help you break them apart after baking.
- Bake to Crispy Perfection:
- Place the tray in your preheated oven. Bake for thirty five to forty minutes. The crackers are ready when the edges look golden and the surface feels dry and firm. For added crispness, you can flip the sheet once midway through.
- Cool Completely:
- Take the tray out and let the crackers cool right on the baking sheet. They will continue to crisp as they cool, so do not rush this part.
- Break and Serve:
- Once cooled, break the crackers along the scored lines or simply snap them into rustic pieces. They are ready for snacking or dipping.

Chia seeds are my secret weapon in this recipe. The way they swell and bind the dough amazes me every time and makes for the perfect crunch. My kids love helping spread the mixture and sneaking tastes before the crackers hit the oven.
Storage Tips
To keep your crackers at their crunchiest, store them in a clean glass jar or airtight container at room temperature. They stay fresh for about a week. Humidity can make them soft, so add a small packet of silica gel or a piece of parchment to absorb moisture. If your kitchen is hot, store in the fridge to prolong crispness.
Ingredient Substitutions
If you run out of flax seeds, you can replace them with sesame or pumpkin seeds for a different texture and flavor. Dried rosemary or oregano stand in beautifully for thyme. Try smoked paprika or even a pinch of chili powder for a spicier kick. Experiment with blends, but stick to whole seeds so the texture stays crisp and hearty.
Serving Suggestions
These crackers are ideal paired with hummus, guacamole, baba ganoush, or any creamy dip. I sometimes top them with cheese and roasted tomatoes for an easy lunch. For parties, arrange on a board with sliced vegetables and olives. They also make a fantastic base for avocado toast or egg salad.
Cultural and Historical Context
Chia and flax have long histories as staple crops in Central America and the Mediterranean. Ancient cultures relied on their nutrition and energy boosting properties. Today, seed crackers tap into this heritage, offering a simple way to enjoy unprocessed foods. The method of binding seeds with water creates a gluten free treat that is both timeless and modern.

Crackers have always brought my family together, from picnics in the park to afternoon snacks around the kitchen table. Each time I bake these, it feels like a small tradition in the making, especially as everyone gathers around to break and share them hot from the oven.
