Did I mention that sourdough discard crackers are a batter cracker?

Yep, you read that right! This recipe uses a batter so no rolling is required!

A crispy, cheesy, fermented sourdough snack cracker.

Course: Appetizer, Baking, Snack
Cuisine: American, Traditional
Keyword: Cheese, Crackers, Fermented, Sourdough, Starter
Servings: 12
Author: Butter For All
  • 340 grams Sourdough Discard (1 1/3 cup, 100% hydration)
  • 113 grams Melted Butter (1/2 cup)
  • 80 grams Grated Parmesan Cheese (1 cup)
  • 5 grams Salt (3/4 - 1 Teaspoon)
  1. Melt the butter and let it cool to room temperature.

  2. Preheat your oven to 325°.

  3. Mix the starter, butter and salt together with a whisk. Whisk briskly until smooth with no visible oiliness.

  4. Add the grated Parmesan cheese and stir it in evenly.

  5. Line a half sheet pan (18"x13") with parchment paper. Using a rubber spatula, spread the batter to the edges of the pan in a smooth even layer.

  6. Place the sheet pan in the midle of the preheated oven and bake for 30 minutes.

  7. After 30 minutes, remove the pan and score the batter with a pizza cutter, making cracker sized squares. Or skip this step and break the crackers later.

  8. If the crackers are noticeably brown at this time your oven may be running hotter than mine. Turn your oven down to 300° and continue with the rest of the recipe.

  9. Return the pan to the oven and continue baking for 30 more minutes.

  10. Turn the oven off and open the door 1/4 of the way. Let the crackers cool completely in the warm oven.

  11. Store the finished crackers in an air tight container.

    • Hi Emily,

      100% hydration is when you keep your starter made with equal weight flour and water. This is my technique for having consistency with recipes. I always keep my starter at 100% hydration and I know that one cup of starter weighs 250g. You can find a lot more info in this guide. I typically keep between 300-600g of starter on hand and I always remove some “the discard” prior to feeding it in preparation for baking. Recipes that call for discard are going to work with fully fermented starter that has already peaked and is no longer suitable for baking bread. I never throw out any starter so my “discard” is always used in recipes like pancakes, crackers, pasta and more.

      I hope this is helpful!

    THESE ARE AMAZING!! So delicious and crazy Easy! I’m making these on the regular and am going to try adding in some rosemary. Awesome recipe and great way to use a lot of discard. Thank you!!

    • Hi Ashley!

      Thank you! When I developed the batter style cracker it was a game changer! Otherwise rolling crackers sometimes felt like a chore. To answer your question, Only turn the oven down if the crackers are already starting to brown! That means any color starting at the edges.

      Hope you love them!

    I’m new to sourdough… I just mixed up my first starter 4 days ago it it’s been so bubbly and active already! Can I use the portion I remove to discard for this recipe at this stage or do I need to wait?

    • Hi Penny,

      Congratulations! Yes you can use it. Make sure to spread the crackers very very thin. A more mature starter will give a final rise in the oven making the crackers lighter, you won’t have that benefit. I would also wait to try baking bread, while it may seem bubbly and active there is a really good chance the bacteria and yeast haven’t balanced out enough to actually leaven bread. Keep going!

    Is the discard you are using fed or unfed?? My starter is in the fridge. When I wanT
    to use it I feed it once…..leave out in off oven for 8 hours till bubbly……feed again(at this point I have discard)……wait another 8 hours…….use the starter in my recipe. Have discard at this point too.

    • Hi Marie!

      That is the perfect kind of discard for this recipe! You can really use either, but I’ve found that if it is fed, and a little more active, the crackers come out lighter with a better texture.
      I think you will love these crackers!

      Let me know,
