What Are Seed Crackers?
Seed crackers are exactly what they sound like – crackers made entirely from seeds bound together with water. Unlike traditional crackers, they contain no flour, making them perfect for people avoiding grains or looking for low-carb options.

These particular multi seed crackers – sometimes called Sama crackers – use five different seeds that create a perfect balance of flavors and textures. The mixture of flax and chia seeds provides the binding power (no eggs needed!), while sesame, sunflower, and pumpkin seeds add flavor and crunch.
Ingredients For Healthy Multi Seed Crackers
These crackers require very few ingredients, making them perfect for last-minute snack preparation:

- Baking tray
- Parchment paper
- Rolling pin
- Sharp knife
How To Make These Seed Crackers Step By Step
Making these crackers is surprisingly simple, though the technique matters for getting that perfect crunch.

Step 1: Mix all the seeds together in a large bowl. Add salt and any spices you like. I find garlic powder, smoked paprika, and dried rosemary work really well together.
Step 2: Take half of the seed mixture and blend it in a food processor until quite fine. This creates a powder that helps bind everything together while keeping the texture interesting.

Step 3: Add the blended seeds back to the whole seeds and mix well.
Step 4: Pour 200ml of boiling water over the seed mixture and stir immediately. The hot water activates the natural gels in the flax and chia seeds.
Step 5: Let the mixture sit for about 10 minutes. It will thicken considerably as the seeds absorb the water.
Note: If your mixture seems too wet after resting, add a tablespoon of extra whole seeds. If it’s too dry, add a splash of more hot water.

Step 6: Line a large baking tray with parchment paper and scoop all the seed mixture onto it.
Step 7: Place another piece of parchment paper on top of the mixture and use a rolling pin to spread it evenly to about 3-5mm thickness. This method prevents sticking and creates a smooth, even surface.
Step 8: Remove the top sheet of parchment paper carefully.
Step 9: Bake in a preheated oven at 160°C (320°F) for 25-30 minutes until the edges start to turn golden and your kitchen fills with a nutty aroma.

Step 10: Using a sharp knife, cut the partially baked crackers into your desired shapes while still warm. This prevents crumbling that might happen if you try to break them after they’re fully cooled.
Step 11: Return to the oven for another 15-20 minutes until completely crisp and golden.

Step 12: Allow to cool completely before storing. They’ll continue to crisp up as they cool.
Did You Know? The binding power in these crackers comes from the natural gels formed when chia and flax seeds meet hot water – the same reaction that makes chia pudding thick!

Why These Seed Crackers Work So Well

What makes these crackers special is the science behind them. When hot water hits flax and chia seeds, they release natural mucilage – a gel-like substance that works as a binder. This means you don’t need eggs, flour, or other ingredients typically used to hold crackers together.
The technique of grinding half the seeds creates the perfect balance between binding power and texture. The first time I made these, I didn’t grind any seeds and they fell apart. When I ground all the seeds, they were too dense. This half-and-half approach works perfectly.
The long, slow baking process is also crucial – it removes moisture gradually without burning, resulting in crackers that stay crisp for days.
Variations To Try
The basic recipe is incredibly versatile. Here are some variations I’ve tried:

- Mediterranean: Add dried oregano, thyme, and a little lemon zest
- Spicy: Mix in chili flakes or cayenne pepper for heat
- Everything Bagel: Add poppy seeds, dried garlic, dried onion, and extra salt
- Sweet: Add cinnamon and a little sweetener for a dessert cracker
Storage And Make-Ahead Tips
These seed crackers store beautifully, which makes them perfect for meal prep:

- Step 1: Make sure the seed crackers are completely cool before storing them.
- Step 2: Store in an airtight container at room temperature.
- Step 3: Add a small piece of paper towel to the container to absorb any excess moisture if you live in a humid climate.
These crackers stay fresh for up to 2 weeks when stored properly, though they rarely last that long in my house!
Note: If your crackers lose their crunch after a few days (which can happen in humid weather), you can refresh them by placing them in a 150°C (300°F) oven for 5-10 minutes.
Nutritional Benefits Of Seed Crackers
These aren’t just tasty – they’re incredibly nutritious. A single serving (about 4-5 crackers) provides:

Each seed brings its own nutritional benefits:
- Flax seeds: Rich in omega-3 fatty acids and lignans
- Chia seeds: High in fiber and antioxidants
- Sesame seeds: Good source of calcium and iron
- Sunflower seeds: Packed with vitamin E and selenium
- Pumpkin seeds: High in magnesium and zinc
Serving Suggestions
These crackers are sturdy enough to hold toppings or dips without breaking. Some of my favorite ways to enjoy them:

- With mashed avocado and a sprinkle of everything bagel seasoning
- Topped with cream cheese and cucumber
- Alongside a bowl of soup instead of bread
- With hummus or baba ganoush
- On their own as a crunchy snack
Top Tip: Pack these in your lunch instead of chips or processed crackers. They’re much more filling and won’t leave you reaching for more snacks an hour later.
