Ingredients & Substitutions

Ingredients for garlic parmesan discard crackers on a table.
  • Sourdough Starter Discard: You can also use an active sourdough starter.
  • Flour: Any type of wheat flour, including whole wheat flour, works here. I went with all-purpose flour for this recipe.
  • Garlic Powder: Stick with garlic powder for this recipe—it blends better than fresh garlic.
  • Fresh Parmesan: Only use fresh parmesan from the block! The store-bought pre-grated parmesan cheese often contains anti-caking agents that can mess with the texture.
  • Butter: Non-dairy butter is an excellent alternative if you’re avoiding dairy.

Variations

Experiment with the flavor of these sourdough crackers by adding dried or fresh herbs to the dough, like basil, thyme, oregano, or rosemary. For an extra crunch, sprinkle on bagel seasoning, sesame seeds, or a pinch of flaky sea salt right before baking.

Peel off the top sheet of parchment paper from the dough, leaving the dough on the bottom sheet.

Cut the dough into 1-inch (2.54 cm) squares using a pizza cutter or a sharp knife.

Use a chopstick to make a hole in the center of each square. Slide the parchment paper with the dough onto a baking sheet.

Step 6:

Bake for 20 minutes or until the crackers are light golden brown.

Let the crackers cool on the baking sheet; they will continue to crisp up as they cool. Repeat with the remaining dough.

Carmyn's TIPS

Forming the dough: After removing the dough from the food processor, it might look a little crumbly at first—don’t worry! Just keep pressing and kneading it together with your hands until it forms a cohesive disc. The warmth of your hands will help bring it all together. Do not add more liquid to the dough; it will come together as you work with it.

Shaping the dough: When rolling out the dough, take your time to shape it into a rectangle. As you roll, lift up the parchment paper and gently press and fold the edges back into the dough to maintain the shape. This process requires a little patience, but it ensures you get an even, consistent thickness and shape, perfect for cutting into squares.

How to Store

Store the garlic parmesan discard crackers in an airtight container at room temperature for up to one week.

INGREDIENTS

  • 4 oz. (112 g) block of parmesan cheese (do not use pre-grated)
  • 1 teaspoon (5 g) garlic powder
  • 4 tablespoons (56 g) unsalted butter (cut into small cubes)
  • ¼ cup (50 g) sourdough starter (fed or discard)
  • 1 cup (120 g) all-purpose flour
  • 2 teaspoons cold water

INSTRUCTIONS

  • Transfer the oven rack to the center position and preheat your oven to 325°F (165°C).
  • Cut the Parmesan cheese into small chunks and pulse them in a food processor until they reach a fine, coarse salt-like consistency. Add the garlic powder and pulse again to distribute it evenly throughout the cheese.
  • Add the cubed butter, sourdough discard, flour, and water to the food processor and pulse until the dough starts to come together. Transfer the dough to a large bowl and use your hands to press it into a cohesive ball (see notes). The dough should be slightly moist but not sticky. If it feels wet, lightly dust it with flour and work it in. If it’s too dry, add another teaspoon of cold water.
  • Divide the dough into two equal portions and shape each into a disc. Place a disc between two sheets of parchment paper and roll it out with a rolling pin into a large rectangle, about ⅛ inch (0.32 cm) thick (roughly the thickness of two stacked quarters). (see notes for tips)
  • Peel off the top sheet of parchment paper from the dough, leaving the dough on the bottom sheet. Cut the dough into 1-inch (2.54 cm) squares using a pizza cutter or a sharp knife. Optionally, use a chopstick to make a hole in the center of each square. Slide the parchment paper with the dough onto a baking sheet.
  • Bake for 20 minutes, or until the crackers are a very light golden brown. Let the crackers cool on the baking sheet; they will continue to crisp up as they cool. Repeat with the remaining dough.
