Step By Step Instructions
- Preheat the Oven:
- Get your oven hot by setting it to 180 Celsius or 356 Fahrenheit. Line a baking sheet with parchment paper or brush it with a thin layer of oil so your crackers do not stick. This ensures crisp edges and easy cleanup.
- Prepare the Onion:
- Finely chop your onion as small as you can. If you want a sweeter milder onion flavor sauté the onion in a pan over low heat with a splash of oil until translucent. Cool it down before adding to your dough so it does not make the crackers soggy.
- Mix the Wet Ingredients:
- In a large bowl combine 100 milliliters of water and 70 milliliters of vegetable oil. Mix them together until thoroughly combined so your dough comes together easily in the next step.
- Combine the Dry Ingredients:
- Whisk together your flour baking powder salt garlic powder and paprika in a separate bowl. Make sure your baking powder is evenly spread for a uniform rise. Adjust the spices to taste if you prefer a little more kick.
- Make the Dough:
- Slowly stir the dry mixture into the wet mixture. Mix until a rough dough forms. Add your onion now and gently knead by hand until all the flour is mixed in and the onion pieces are well distributed.
- Knead the Dough:
- Dust your work surface with a bit of flour. Knead the dough for two or three minutes adding flour if it feels very sticky. The dough should not be dry or crack but should not cling to your hands either.
- Roll Out the Dough:
- Take your dough and roll it to a thickness of about two to three millimeters. Use a sharp knife or pastry cutter to make squares about three centimeters wide. If you want very crisp edges measure as you go.
- Arrange the Crackers on the Baking Sheet:
- Lay out your cracker squares on the prepared baking sheet. Give them a little wiggle room so they bake evenly. For extra crunchiness prick the center of each cracker with a fork.
- Bake:
- Slide your tray into the hot oven and bake for about ten to twelve minutes until the edges are deep golden and the crackers sound crisp when tapped. Every oven is a little different so watch the last few minutes and pull them out as soon as they brown.
- Cool and Serve:
- Let the crackers cool completely on a wire rack. They will crisp up even more as they cool. Store them in an airtight jar or eat them right away with cheese dips or just on their own.

I always end up sneaking more onions into the batch just for that extra pop of sweetness. My daughter made these for the school bake sale last year and the whole tray was gone before recess.
Storage Tips
Keep your crackers in a well sealed container at room temperature. They stay crisp for five to seven days this way. If you find they soften up a bit just pop them in a hot oven for three minutes to revive their snappiness. Avoid storing in the fridge as moisture will soften them.
Ingredient Substitutions
Swap in whole wheat flour for a nuttier flavor though the texture will be slightly more rustic. You can use red onion for a sharper taste or shallots for something milder. Olive oil substitutes well for vegetable oil bringing a peppery note. Smoked paprika or a sprinkle of dried herbs adds another layer of complexity if you are feeling adventurous.
Serving Suggestions
Pair these crunchy crackers with soft cheeses like goat cheese or a smoky gouda. They are perfect for dips such as hummus or homemade salsa. Toss a handful on top of creamy tomato soup or crumble them over salads for a satisfying crunch. My family loves them as a lunchbox snack with fresh veggies.
Cultural and Historical Context
Crackers have been a staple snack across many cultures from classic matzo to Italian grissini but homemade versions became especially popular in Eastern Europe for stretching small amounts of flour and flavoring with whatever was on hand like fresh onions. Making crackers from scratch lets you tap into that homemade tradition and bring a unique twist to your table.

Enjoy every crunchy bite—these crackers never last long at our house so consider making a double batch.
