What is Gluten-Free Sourdough Discard Crackers

If you’re asking yourself, “Wait, what on earth are Gluten-Free Sourdough Discard Crackers?” don’t worry—you’re not alone. Essentially, these crackers are thin, tasty snacks made from the “discard” you’d normally toss when refreshing your gluten-free sourdough starter. Sounds kinda magical, right? You get all the flavor and crunch with none of the gluten and, let’s be real, none of the guilt for wasting your starter.

Here’s what makes them clutch. That starter discard packs a sourdough punch—tangy, savory, sometimes a bit cheesy—and it blends with just a few other pantry basics. Baked up, they come out shatteringly crisp (totally rivaling the five-dollar stuff at fancy shops). I’ve tried ‘em with family and friends, and they’re honestly always surprised they started with “waste” instead of fresh ingredients. If you love easy snacks with big flavor, these are a game changer. Plus, you only need like 30 minutes, real talk.

Recipe Ingredient Notes

For Gluten-Free Sourdough Discard Crackers, you really don’t need a laundry list, which is great for me because I hate overcomplicating things. I mean, who has time for twenty weird ingredients? Here’s what you need and a few thoughts (or warnings?) on each one:

Gluten-free sourdough discard: This is the byproduct from feeding your gluten-free starter. Don’t use the active bubbly stuff—you want the excess you’d normally toss.

Gluten-free flour: I usually go for a basic 1:1 cup-for-cup blend, nothing fancy. If you’re still figuring out which gluten-free flour blends work best for your baking, that guide has you covered.

Oil: Olive oil or avocado oil are my faves. Both give crackers a little richness and help with the crispi-ness. Don’t skip this or you’ll get weird, dry results.

Salt: It goes in the dough and sprinkled on top. Maldon salt is a good show-off, but whatever works.

Optional: Herbs, seeds, garlic powder, or, for the risk-takers, a pinch of chili flakes. Go wild or keep it plain. Totally up to your mood.

That’s really it! Most of the time, you probably have this stuff lying around from other baking projects or sourdough experiments.

Ingredient	Purpose	Notes
Gluten-Free Sourdough Discard	Base flavor and texture	Use the excess after feeding the starter
Gluten-Free Flour	Structure	1:1 blend recommended for best results
Olive or Avocado Oil	Helps with crispiness	Don’t skip this, or the crackers may turn out dry
Salt	Flavor enhancer	Use both in the dough and on top
Optional Seasonings (like herbs)	Flavor boosters	Get creative with flavors to match your mood

How to Make Gluten-Free Sourdough Discard Crackers

Ok, you ready? This is a bare-bones, totally doable process (seriously, you could do this before lunch if you wanted). Here’s how it goes:

First, mix the gluten-free sourdough discard, a splash of oil, a little salt, and your gluten-free flour in a bowl. No fancy gear, an old spatula works fine—just make sure there’s no unmixed flour hiding in the edges.

Once it’s a shaggy dough (that’s not a technical term), dump it onto a piece of parchment paper. Now roll it out as thin as possible. I mean, really thin—the thinner, the crispier. It’ll try to stick, so cover with another parchment sheet or plastic wrap. If you’re struggling with shaping gluten-free bread or doughs in general, the techniques in that guide apply here too.

Peel off the top, score with a knife or pizza cutter into whatever size cracker you want, sprinkle with more salt, and pop it in a hot oven.

Bake for around 20 minutes until golden. If the edge crackers crisp up quicker (and they always do), just snag those and put the rest back in. Hey, nothing wrong with working in batches!

Let cool. If you eat them warm, they’ll be a tad chewy. Wait a hot minute (okay, 10), and they’ll snap just right.

Gluten-Free Sourdough Discard Crackers Variations

If you’ve made these Gluten-Free Sourdough Discard Crackers once, you’re never locked in. My kitchen? Basically a cracker lab at this point. Let’s be real—plain is cool, but a little jazz never hurt anybody.

Mix in some rosemary and cracked pepper for herby vibes. Even my picky cousin goes for those. Got leftover seeds? Toss in sesame or poppy, coat the tops, or basically bury the dough in ’em. Feeling bold? Smoked paprika, a pinch of cumin, maybe some nutritional yeast if you want vegan “cheese” flavor. You can even go sweet—cinnamon and coconut sugar. (Oddly good, trust me.)

Sometimes I go with Italian seasoning if all else fails, because it makes my house smell like an actual pizzeria—speaking of which, if you’re loving the sourdough discard game, you’ve got to try turning that starter into gluten-free sourdough pizza dough next. And if you’re getting really ambitious with your sourdough starter, gluten-free sourdough bagels are another fantastic way to put that active starter to work. And no, I don’t measure—I sprinkle til it looks “right.” You do you, truly!

How to Serve Gluten Free Crackers

Let’s be honest, there’s no wrong way to eat a cracker, but here are my favorites:

• Pile ’em with cheese (goat cheese and fig jam is fancy, y’all)
• Dunk in soup, like a classic tomato or something brothy
• Crunch up over salads, instead of boring gluten-free croutons
• Smear with hummus or nut butter for a speedy snack

A couple days in a sealed jar and they’re still awesome (unless someone eats them all, which usually happens at my house). They’re also excellent for lunchbox trading, just saying! For more ideas on what to do with your homemade gluten-free goodies, check out our leftover gluten-free bread ideas.
