Why You'll Love These Seed Crackers

One-bowl preparation: Stir the ingredients together, let the mixture thicken and spread it onto the tray.
No kneading or rolling: A spatula is all you need to shape the mixture before baking.
A generous batch: The recipe makes approximately 60 crackers, depending on the size of the pieces.

I like how straightforward the preparation is: everything comes together in one bowl, and the brief rest makes the mixture easier to spread. There is no dough to roll out or individual crackers to shape. Once baked and cooled, they are ready to scoop up something smooth, such as my hummus without tahini.

I keep the seasoning simple so the seeds provide most of the flavor. The small amount of almond flour sits between the seeds, while the sunflower and melon kernels give the crackers their more substantial bite. They also pair well with homemade labneh, which brings a creamy contrast without hiding the seed texture.

Key Ingredients in Seed Crackers

The full quantities are in the recipe card below. These are the ingredient details that matter most:

Whole flax seeds and chia seeds: These form part of the base and help the mixture hold together as it hydrates. Use whole flax seeds for the texture shown in the photographs.
Sunflower and melon seed kernels: Use shelled, raw, unsalted kernels. They add bite without bringing extra salt into the mixture.
Almond flour: A small amount fills the spaces between the seeds and helps give the baked sheet structure. Keep it in the mixture alongside the whole seeds.
Boiling water and salt: The water hydrates the mixture during the short rest, while the salt seasons the crackers. No added oil is needed.

How to Make Seed Crackers

The printable recipe card includes the full measurements and instructions.

1. Combine the dry ingredients: Mix the seeds, almond flour, and salt in a large bowl, distributing the smaller seeds throughout the mixture.

2. Add the water and rest: Stir in the boiling water, then leave the mixture for 5 minutes until thick and sticky.

3. Spread and bake: Press into a thin, even layer on a parchment-lined baking sheet. Bake at 320°F convection (160°C fan) for approximately 1 hour, until golden at the edges and dry and firm across the surface.

4. Cool and cut: Let the crackers cool slightly on the tray, then cut into pieces. Allow them to cool completely before serving or storing.

Tips for Crispy Seed Crackers

Keep the thickness even: Thick patches can stay soft while thinner areas become golden. Smooth the center as carefully as the edges before baking.
Let the mixture thicken: Give it the full rest before spreading. The sticky consistency helps keep the seeds together on the tray.
Check more than the edges: Golden edges alone do not tell you whether the middle is ready. Look for a dry, firm surface across the sheet.

How to Keep Seed Crackers Crispy

Cool the crackers completely before transferring them to an airtight container. Sealing them while warm can trap moisture and soften the texture. Store at room temperature and use within 5 days for best texture

What to Serve with Seed Crackers

Serve them with muhammara for a roasted pepper dip, beet hummus for a colorful spread, or creamy dill sauce for an herby accompaniment. Add them to a cheese board, or serve alongside a salad when you want something crunchy.

Ingredients

Instructions

Preheat the convection/fan oven to 160 °C. Line a large baking sheet with parchment paper.
In a large bowl, combine 180 g whole flax seeds, 135 g raw, unsalted sunflower seed kernels, 40 g raw, unsalted melon seed kernels , 60 g chia seeds, 30 g almond flour, and 1 teaspoon saltStir until evenly mixed.
Pour in 350 ml boiling water and stir thoroughly. Let the mixture rest for 5 minutes, until thick and sticky.
Transfer the mixture to the prepared baking sheet. Use a spatula to press and spread it into a thin, even layer, avoiding thicker patches in the center.
Bake for approximately 1 hour, until the edges are golden and the surface is dry and firm. The center should be set rather than soft or damp.
Leave on the tray to cool slightly, then cut into cracker-sized pieces. Allow the crackers to cool completely before serving or storing.

Notes

Keep the seed proportions: Flax and chia help bind the mixture, so avoid replacing them with extra sunflower or melon seeds.

Spread without gaps: Press the mixture into a continuous, even layer. Gaps and very thin patches can make the crackers fragile.

Cut before fully cooled: Let the baked sheet cool slightly, then cut into pieces while it is still a little warm to reduce crumbling.
