Buttery Parmesan Sourdough Discard Crackers

I may receive commission if you purchase through links in this post.

These super cheesy, super crispy sourdough crackers are made with sourdough discard, the fully fermented portion of your starter that is removed before feeding. These are the easiest sourdough crackers with the best digestibility and the most real cheese flavor! #starter #sourdough #wildyeast #fermented #realfood #wisetraditions #crackers #cheesecrackers #healthysnacks #easy #crunchysnacks


You didn’t think I would stop with my super awesome Rosemary and Olive Oil Sourdough Discard Crackers did you?

No way! Once I realized what a huge success my discard crackers were I wanted to make all the flavors. This recipe takes four ingredients and turns them into a super cheesy, super crunchy, super healthy sourdough snack!

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!

Watch the technique in my YouTube presentation.

Buttery Parmesan Sourdough Discard Crackers

Yield: 12 Servings
Prep Time: 5 minutes
Cook Time: 1 hour
Total Time: 1 hour 5 minutes

A crispy, cheesy, fermented sourdough snack cracker.


  • 340 grams Sourdough Discard, (1 1/3 cup, 100% hydration)
  • 56 grams Melted Butter, (1/4 cup)
  • 80 grams Grated Parmesan Cheese, (1 cup)
  • 5 grams Salt, (3/4 - 1 Teaspoon)


  1. Melt the butter and let it cool it to room temperature. This step is very important, if the butter is not fully cool it will not incorporate into the batter.
  2. Preheat your oven to 325°.
  3. Mix the starter, butter and salt together with a whisk. Whisk briskly until the batter is smooth with no visible oiliness. If the batter is breaking, the butter may have been too warm. Stick the batter in the fridge for 20 minutes and then try whisking it again!
  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.


Please note: I have changed the quantity of butter in this recipe since its original publication date. I apologize for any inconvenience and sincerely hope you have an amazing experience making these crackers.

Just made these this morning and they are delicious! I confess I did not wait until they fully cooled down :) I doubled the recipe and made one batch per the recipe and sprinkled sesame seeds to the second batch. I did not have enough grated Parmesan cheese so I completed the amount with shredded Parmesan. They turned out great! Thinking of adding smoked paprika, or maybe red pepper flakes for a spicy twist. This discard recipe is definitely one to keep and put on repeat! Happy baking!

I don't know what I did right but these turned out wonderful. I am new to this Sourdough endeavor and was short on the amount of discard that I had.I had enough discard for about 1/3 of what was called for. I made the changes in amounts of ingredients and sprinkled Chia seeds and Rosemary on top. I can't tell you how yummy they turned out.

Pan size seems way to big. The batter was super thin and didn’t fill the pan.

Hi Audrey,

The "Half-Sheet" Pan size should be perfect. If you have a full sheet pan, it would be too big. But honestly, its good if it doesn't reach the edge, sometimes it's even better to split the batter because the thinner the better!!!

I made these today with nutritional yeast rather than cheese and ate about half the pan already! Delicious and a great way to use up a lot of starter all at once! Thanks for the easy recipe :)

How much nutritional yeast did you use, the same amount?
