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!

A large bowl of sourdough discard crackers made with real butter, real Parmesan, and fully fermented sourdough discard.

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 (1 1/3 cup) sourdough discard at 100% hydration
  • 56 grams (1/4 cup) melted butter
  • 80 grams (1 cup) grated Parmesan cheese
  • 5 grams (3/4 to 1 teaspoon) salt


  1. Melt the butter and let it cool 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°F.
  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 by 13-inch) 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 middle 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°F 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 airtight 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.

I’m not sure how I read this recipe so many times and saw 34 g of starter every time I read it (and even thinking wow that’s not much)… and still continued. It isn’t until after baking I realized it’s 340!!!! HOWEVER, I do not recommend this recipe with 34g whatsoever. My terribly burnt extreme flavor black cheese it’s are a 0/10. I’ll be trying this recipe again tomorrow once I go buy a new thing of Parmesan. -__-

Hey Madison,

Ugh. I'm so sorry that happened. I hope the next batch makes up for it!

LOVE this cracker recipe! I did make a small change, as the first time I made these they were a tad greasy. I decreased the amount of butter to 3 T and the crackers were perfect. Also, sometimes I add garlic powder (not garlic salt) for all the garlic lovers in my family!

This is a great way to use the discard that I can't bear to throw away. Thanks for a wonderful recipe!

Hi Cindy!

I'm so happy to hear you like the recipe. It's always really wonderful when someone can adapt a recipe and make a change for the better! Thanks for sharing!

I have a batch of these in the oven right now. I don't use a microwave and I don't always feel like melting butter on the stove so used room temperature ghee instead. It mixed right in. Hopefully these turn out!

Hi Ashley!

I hope so! I also agree ghee is a great choice! Well done and thanks for the feedback :)

Thank you for this! I have only found recipes that require you to add fresh flour and I can only eat fermented flour. So this is wonderful! unfortunately I didn't find it in time, but I am certainly going to use your recipe the next time I make crackers! (I just made sourdough discard with some baking soda and baking powder and sprinkled it with everything bagel. I have no idea how they are going to be a they look okay I guess a little thick though.) Thank you again for taking the time to write up and post this recipe!

Hi Liz!

I'm so excited to hear how you like these when you get a chance to try them! All my sourdough recipes use a long slow ferment (usually overnight) because I'm the same, I only eat fully fermented wheat! I have several variations of the discard batter crackers, as well as some that use an overnight fermentation. So there are lots to try to find your favorites! I also have a new cracker coming soon, so watch out for that one, not to toot my own horn, but IT'S SO GOOD!

Happy baking!
