Crispy Sourdough Discard Tortilla Chips Recipe

Table of Contents

Sourdough discard tortilla chips turn your leftover starter into crispy, golden snacks that taste far better than anything from a bag.

Sourdough discard tortilla chips are one of the smartest things you can make when that jar of unfed starter is sitting on your counter, begging for a purpose. Instead of pouring it down the drain, you press it into thin rounds, season them simply, and bake them into crackling, tangy chips that hold up beautifully under guacamole, salsa, or a hearty bowl of soup. It is a small effort with a genuinely satisfying result.

What makes this version worth your time is the starter itself. The natural fermentation in sourdough discard adds a gentle tang and a depth of flavor that plain corn or flour chips simply cannot replicate. The batter comes together in minutes, rolls out thin without fuss, and bakes into chips that are crisp all the way through — not soft in the middle, not brittle at the edges. The method is forgiving, the ingredients are pantry staples, and the result is a snack you will want to keep making on repeat.

Serves

4 servings

Ingredients

1 cup sourdough discard (unfed, 100% hydration)
1 cup all-purpose flour, plus more for dusting
1/2 cup masa harina (corn flour)
2 tbsp olive oil
1 tsp fine sea salt, plus extra for topping
1/2 tsp garlic powder
1/2 tsp cumin
2–3 tbsp water, as needed to bring dough together

Instructions

1. Preheat oven to 375°F (190°C) and line two large baking sheets with parchment paper.
2. Combine sourdough discard, all-purpose flour, masa harina, olive oil, salt, garlic powder, and cumin in a large mixing bowl and stir until a shaggy dough forms.
3. Add water one tablespoon at a time, kneading until a smooth, pliable dough comes together — it should not be sticky.
4. Divide dough into 4 equal portions and work with one at a time, keeping the rest covered with a damp towel.
5. Roll each portion on a lightly floured surface as thin as possible, aiming for about 1–2mm thickness.
6. Cut each rolled sheet into triangles using a pizza cutter or sharp knife, roughly 2-inch pieces.
7. Arrange triangles in a single layer on prepared baking sheets, sprinkle lightly with additional sea salt.
8. Bake for 16–20 minutes, rotating the pans halfway through, until chips are golden-amber and crisp at the edges.
9. Remove from oven and allow to cool completely on the pans — they will crisp up further as they cool.
10. Serve with guacamole, salsa, or your favorite dip and enjoy immediately or store in an airtight container.

Tips & Notes

– The thinner you roll the dough, the crispier the chips — use a pasta machine on the widest setting for ultra-thin results.
– Unfed discard works best here; it provides tang without making the dough too wet or active.
– For extra flavor, add 1/4 tsp smoked paprika or chili lime seasoning to the dough.
– Store cooled chips in an airtight container at room temperature for up to 5 days.
– If chips soften over time, re-crisp them in a 350°F oven for 4–5 minutes.

The secret is hydration and thinness working together. Sourdough discard already contains water, flour, and wild yeast activity, which means the dough you build around it has structure without needing much added fat. A small amount of oil keeps the chips tender enough to snap cleanly rather than shatter into dust. Rolling the dough as thin as possible — you want to nearly see through it — is the single most important step for getting that satisfying crunch. The mild acidity from the discard also means the chips brown evenly in the oven without needing high heat that could burn the edges before the centers catch up. Thin dough and moderate heat are your two non-negotiable factors here.

What You Will Need to Make These Chips

You do not need anything exotic. Start with your sourdough discard — it can be anywhere from a day old to about a week old, straight from the refrigerator or at room temperature. Either works, though a slightly warmer discard will be easier to mix. All-purpose flour is the backbone; it gives the dough enough gluten to roll without tearing. A small pour of a neutral oil — sunflower, avocado, or any light cooking oil — keeps the chips from going leathery. Salt is essential, and you will use it both inside the dough and sprinkled on top just before baking. Beyond that, the seasoning is completely up to you. Cumin, smoked paprika, garlic powder, dried oregano, and chili flakes are all excellent starting points. A little lime zest stirred into the dough adds a bright, citrusy lift that pairs beautifully with fresh salsa.

How to Make Sourdough Discard Tortilla Chips

Begin by whisking together your sourdough discard, oil, and salt in a mixing bowl until smooth. Add flour gradually, stirring with a wooden spoon or a flexible spatula, until the dough comes together into a soft, pliable ball. It should feel a little like play dough — soft enough to press flat easily, firm enough not to stick to your hands. If it feels too sticky, add flour a tablespoon at a time. If it feels stiff or dry, a small splash of water will bring it back.

Divide the dough into four roughly equal portions. Working with one portion at a time and keeping the others covered with a clean towel so they do not dry out, place the dough between two sheets of parchment paper. Roll it out as thin as you can manage — ideally around one to two millimeters. The parchment prevents sticking and makes it easy to transfer the whole sheet directly onto a baking tray.

Peel off the top sheet of parchment, brush or spray the surface lightly with oil, and scatter your chosen seasonings across the top. Use a sharp knife, a pizza wheel, or a bench scraper to cut the dough into triangles, strips, or rough rectangles. You do not need to separate the pieces at this stage — they will pull apart easily once baked.

Slide the parchment and dough onto a baking sheet and bake at around 350 degrees Fahrenheit, checking after ten minutes. The chips are ready when the edges have turned a light golden color and the centers feel dry to the touch, not soft or springy. Depending on how thin you rolled them, this usually takes between twelve and eighteen minutes total. Watch them closely in the final few minutes — they go from perfectly golden to overdone quickly. Pull the tray out and let the chips cool completely on the parchment before breaking them apart. They will crisp up further as they cool, so resist the urge to judge them straight from the oven.

Tips for Getting the Best Crunch Every Time

Roll the dough on the thinner side of what feels comfortable. Thicker rounds bake into something closer to a flatbread cracker, which is pleasant but not the same as a true chip.
Do not skip the resting step if your dough keeps springing back when you roll it. Cover it and let it rest five minutes; the gluten will relax and rolling becomes much easier.
Season generously on top. The dough inside is only lightly salted, so the topping is where most of the flavor lands.
Bake one sheet at a time if your oven runs hot or uneven. Rotating the tray halfway through helps the chips color uniformly.
Let the chips cool fully before storing. Even a little residual warmth trapped in a container will soften them.

Ways to Change Up the Flavor and Shape

One of the real pleasures of making your own chips is how easily the recipe adapts to whatever mood or meal you have in mind.

Spiced and smoky: Mix a generous pinch of smoked paprika, cumin, and a small amount of chipotle powder into the dough itself, then finish with flaky salt on top. These are particularly good alongside a bowl of black bean soup.
Herbed and savory: Stir finely chopped fresh rosemary or thyme into the dough, and finish with a light dusting of garlic powder and grated hard cheese before baking. The cheese crisps into a lacey, savory crust.
Seeded and nutty: Press sesame seeds, poppy seeds, or a mix of both onto the surface after brushing with oil. These have a satisfying density and work well with hummus or a yogurt-based dip.
Citrus and chili: Add lime zest directly to the dough and dust the tops with a mild chili powder and a pinch of sugar. The balance of heat and citrus is bright without being sharp.
Everything-seasoned: Use a generous layer of everything-bagel seasoning on top — a mix of sesame seeds, dried garlic, dried onion, poppy seeds, and flaky salt. These disappear fast.
Thicker cracker-style: Roll a portion slightly thicker, cut into rectangles, and bake a few minutes longer. These turn into sturdy dipping crackers that hold up to thicker dips without breaking.

How to Store These Chips and Keep Them Crispy

Once the chips are completely cool — and this really does mean fully cool, not just warm — transfer them to an airtight container. A wide-mouth jar, a resealable bag with the air pressed out, or a tin with a snug lid all work well. Kept at room temperature away from moisture and direct sunlight, the chips stay crisp for up to five days, though they rarely last that long.

If they soften after a day or two — which can happen in humid kitchens — spread them in a single layer on a baking sheet and put them back into a low oven at around 300 degrees Fahrenheit for five to eight minutes. Let them cool again completely before returning to the container. They will come back to their original crunch without any noticeable change in flavor.

These chips do not freeze well once baked, but you can freeze the unbaked, rolled-out dough between sheets of parchment for up to a month. Thaw it overnight in the refrigerator, bring it to room temperature, then proceed with seasoning and baking as usual.

Frequently Asked Questions About Sourdough Discard Chips

Does the discard need to be active or fed? No. Unfed discard — the portion you would normally throw away during a feeding — works perfectly here. It does not need to be bubbly or recently fed, just not dried out or moldy.

Can you make these without any added flour? Pure discard alone is too wet and thin to roll into chips. The added flour is what gives the dough enough body to hold its shape during baking.

What if the chips are still soft after baking? They were likely rolled too thick or pulled from the oven a little early. Return them to a 325-degree oven for another five minutes, then let them cool fully on the tray. Cooling on a wire rack instead of the pan can also help air circulate and encourage crisping.

Can you make these in an air fryer? Yes. Working in small batches, arrange the cut dough pieces in a single layer in the basket without overlapping. Air fry at 350 degrees Fahrenheit for six to nine minutes, checking at the six-minute mark. They brown quickly in the air fryer, so stay close.
