Crispy Sourdough Cheddar Crackers (Homemade Cheez-It Style)

A bowl of crispy homemade sourdough cheddar crackers served with flaky sea salt on a wire cooling rack.

Cheez-Its, but make them sourdough.

These sourdough discard cheddar crackers are basically homemade Cheez-Its, and Cheez-Its are a big deal in my family. They’re our road trip snack, the box that gets passed around the car until someone shakes it and hears nothing. These have that same sharp, salty, keep-reaching-for-more thing going, plus a little tang from the discard that the box version can’t touch.

If you keep a sourdough starter, you already know how fast discard piles up. I feed mine almost every day to keep it strong for bread baking (with the occasional stretch where it sits in the fridge longer than I’d like to admit), so I always have discard on hand. There are plenty of ways to use it up, but this recipe is one of my go-tos because it uses a lot of discard with barely any extra ingredients or time.

The dough comes together in one bowl. No rolling pin, no chilling, no cutting individual crackers. You mix, spread the dough thin over parchment, bake, score, and bake again until crisp.

One tip from my kitchen: I spread the middle of the pan a little thicker on purpose. My daughter loves the chewy center crackers, and I like the crispy edges, so we each have our territory. Once the pan cools, we always grab a little handful every time we walk by. It took me a lot of batches before I could even test how to store leftovers, because they usually don’t make it off the pan.

Ingredients You’ll Need

Ingredients for homemade sourdough cheddar crackers including sourdough discard, shredded cheddar cheese, butter, and sea salt.
  • Sourdough discard: Unfed sourdough discard adds tangy flavor and helps create a crisp cracker.
  • Sharp cheddar cheese: Freshly shredded sharp cheddar melts more evenly and gives these crackers their rich, cheesy flavor.
  • Unsalted butter: Melted butter adds richness and helps create a crisp, tender texture.
  • Fine sea salt: Seasons the dough and enhances the cheddar flavor.

How to Make Sourdough Cheddar Crackers

Step 1: Mix the Dough

Stir together the melted butter and sourdough discard until smooth. Add the shredded cheddar and fine sea salt, then mix with a thin silicone spatula until evenly combined.

Step 2: Spread the Dough

Spread the dough onto a parchment-lined baking sheet in a thin, even layer about 1/8 inch thick. It should be almost transparent in a few spots near the edges. If you want chewier crackers, leave the center slightly thicker. Sprinkle evenly with flaky sea salt.

Step 3: Partially Bake

Bake at 375°F for 15 minutes. The dough should be set but still pale.

Step 4: Score the Crackers

Using a pizza cutter, score the dough into bite-sized squares while it’s still warm.

Step 5: Poke the Centers

Use a skewer or toothpick to poke a small hole in the center of each cracker. This helps them bake evenly and gives them that classic Cheez-It look.

Step 6: Finish Baking

Return the pan to the oven for 20 minutes, rotating halfway through. The crackers are done when they are deep golden brown and crisp across the entire pan.

If a few crackers are still slightly soft, turn off the oven and let them sit inside with the door cracked open for 5 to 10 minutes.

Prep Time 10 minutes
Cook Time 35 minutes
Servings: 70 crackers
Course: Snack
Cuisine: American
Calories: 15

Ingredients
  

  • 200 g sourdough discard (unfed, stirred)
  • 2 tbsp unsalted butter (28 g), melted and slightly cooled
  • 1/4 tsp fine sea salt (1.5 g)
  • 113 g finely shredded sharp cheddar cheese 1 cup, finely shredded
  • 2 to 3 g flaky sea salt for topping, to taste

Equipment

  • Rimmed Baking Sheet
  • Parchment Paper
  • Mixing Bowl
  • Thin silicone spatula
  • Pizza Cutter
  • Skewer, Straw, or Toothpick

Method
 

  1. Preheat and Prepare
    Preheat the oven to 375°F (190°C). Line a rimmed baking sheet (approximately 11 × 14 inches / 28 × 35 cm) with parchment paper.
  2. Mix the Dough
    In a medium mixing bowl, stir together the sourdough discard and melted butter with a thin silicone spatula until smooth. Stir in the fine sea salt, then add the shredded cheddar cheese and mix until evenly combined. The dough will be thick but easily spreadable.
  3. Spread the Dough
    Transfer the dough to the prepared baking sheet.
    Using the same silicone spatula or an offset spatula, spread the dough into a thin, even layer about 1/8 inch thick, almost transparent in a few spots near the edges. Sprinkle evenly with the flaky sea salt.
    💡 Tip: The thinner the dough, the crispier the cracker. If you like a chewier cracker, leave the center of the pan slightly thicker on purpose. That is how I do it, since my daughter prefers the chewy ones and I go for the crispy edges.
  4. Bake, Score, and Finish Baking
    Bake for 15 minutes.
    Remove from the oven and score into small squares with a pizza cutter. For the classic Cheez-It look, poke a small hole in the center of each square using a skewer, straw, or toothpick, if desired.
    Return to the oven and bake for 20 minutes, rotating the pan halfway through for even browning.
    The crackers are done when they're deep golden brown and crisp. If a few areas still feel soft, turn off the oven and leave the pan inside with the door cracked open for 5 to 10 minutes to finish crisping.
  5. Cool and Store
    Let the crackers cool completely on the baking sheet.
    Break apart along the scored lines and store in an airtight container at room temperature for up to 1 week.

Notes

Discard: Use unfed sourdough discard for the best tangy flavor. Stir well before measuring.
Butter: Melt the butter and let it cool slightly before mixing so it blends smoothly into the discard.
Cheddar: Sharp or extra-sharp cheddar provides the boldest flavor. Finely shredded cheese melts more evenly throughout the crackers.
Spread It Thin (Or Not): Spread the dough into a thin, even layer about 1/8 inch thick, almost transparent in a few spots near the edges. That thinness is what makes them crispy. If you want both textures in one pan, leave the center slightly thicker for chewier crackers and keep the edges thin for crispy ones.
Optional Flavor Boosters: For a little extra flavor, stir one of the following into the dough when adding the fine sea salt:
• ¼ teaspoon (1 g) smoked paprika for a subtle smoky flavor
• 1 to 2 teaspoons (5 to 6 g) nutritional yeast for an extra savory, cheesy flavor
Storage: Store the crackers in an airtight container at room temperature for up to 1 week.
Refresh Tip: If the crackers soften after a few days, bake them at 300°F for 3 to 5 minutes, then let them cool completely. They’ll crisp right back up.
