Crispy crackers

Possible with sourdough

Today I brought you a wonderfully crunchy snack: my crispy crackers. You can always modify this recipe as you wish and try new versions. So it is a basic recipe with which you can be wonderfully creative yourself. You can even use leftover sourdough in two different ways. Best of all, these crackers are super quick and easy to make and really tasty! ♥

Quick crispy snack

The idea came to me after I saw the Tarte flambée with pears, camembert & walnuts had baked. Because the dough is so nice and thin, wonderfully crispy and, above all, delicious. So I thought, that must be an ideal basis for crackers. No sooner said than done ... So knead the dough again and bake crackers out of it. Since then even a few times and the crackers have always been super tasty and deliciously crispy. Above all, they are significantly healthier than fatty chips and simply wonderfully variable! Because whether with sesame like here in the pictures, with herbs, cheese or just salt flakes. Almost anything is possible! So the crispy crackers can be varied according to needs and taste. You can even “get rid of” sourdough that is no longer needed.

Sourdough utilization

On the one hand, of course, it works in the classic way in the dough. To do this, the appropriate amount of flour and water is simply deducted from the recipe. This gives the dough itself a nice aroma. On the other hand, you can simply spread your sourdough very thinly on the dough before baking. Depending on how spreadable it is, it should be diluted with a little water beforehand if necessary. Herbs or spices can also be mixed in here. By the way, this is my insider tip (even if something is misappropriated) for the crispy crackers Chipotle Butter Seasoning and the BBQ cracked pepper. Super tasty and something completely different. Because the slightly sweet heat or the slightly smoky BBQ note go perfectly with snacks. In any case, we thought both combinations were brilliant!

→ Sourdough as Sourdough spreads
  • Simply use some liquid to brush the dough.
  • This can be seasoned beforehand with spices, herbs, garlic.
  • Thick or solid sourdough must first be dissolved in water or diluted until a finely spreadable mixture is created. 


→ Sourdough as Dough ingredient
  • The sourdough can simply be kneaded in. 
  • In doing so, flour and water are withdrawn from the recipe accordingly.
  • Example of liquid sourdough like Levain (TA 200): For 150 g of sourdough, 75 g less water and 75 g less flour are added to the dough.
  • Example of solid sourdough like Lievito Madre (TA 150): For 150 g sourdough / LM, 50 g less water and 100 g less flour are added to the dough.

  1. you write: permanent baking foil or baking paper - my permanent baking foil and the baking paper have to be stated in the instructions for use - up to 220 degrees. which products do you use?

    thank you for the information,

    1. Dear Erika,

      I pay extra attention to this when buying. I prefer to use grill mats that go up to 300 ° C. Got it from Amazon and also use it for pizza.
      There are also different ones, but it always says how high it can be heated.

      Many greetings,

    Dear Sonja, bad news: the crackers are addicting🤗🤗
    Do you still have an idea how you can increase the adhesion of the sprinkling (herbs, etc.)? Maybe spray lightly with water?
    LG Sieglinde

    1. Yes, spray it with water or, if you have some spare, brush it with egg white, then everything will hold up great. What works well, dilute a little sourdough with water and apply thinly, then sprinkle with seeds, also brings additional aroma.
