Sourdough Tortillas: Soft, Chewy, and Naturally Leavened (2026)
📖 6 min read · Updated August 2026
By SourdoughCalc Team
A sourdough tortilla is what happens when you treat a flatbread the way you treat a loaf. The wild yeast and lactobacilli in your starter do the same long, slow work on masa or wheat flour that they do on bread dough. The result is more digestible, more flavorful, and keeps longer than a standard flour tortilla, with a slightly tangy edge that is unmistakably sourdough.
This guide covers both the active-starter version (which takes 8 to 12 hours) and the discard version (which uses up your leftover starter while you are at it). Pick whichever fits your schedule.
Active Starter vs Discard: Pick Your Path
Active starter version: 1 cup of recently fed, bubbly starter gives the tortillas the most flavor and the best rise. Requires 4 to 6 hours of fermentation after mixing. Best flavor, softest texture. Worth the wait if you have the time.
Discard version: Use unfed starter straight from the fridge. The wild yeast and bacteria are less active, so you get a denser, more cracker-like tortilla with milder flavor. No extra time beyond the mixing. Great way to use up discard instead of throwing it out.
The Basic Recipe (Makes 8 Tortillas)
The recipe scales easily. Use the calculator on the homepage to convert to your exact flour weight, then divide by 8 to size each tortilla.
Ingredients:
250 g all-purpose or bread flour
150 g water (60% hydration — stiffer than bread, good for rolling thin)
50 g active sourdough starter (or 50 g discard)
5 g salt
15 g olive oil or melted lard
Method:
1. Mix everything in a bowl until no dry flour remains. Cover and rest 30 minutes.
2. Knead briefly (2 to 3 minutes) until smooth. Cover and ferment 4 to 6 hours at room temperature (active starter version) or 1 hour (discard version).
3. Divide into 8 equal pieces (~58 g each). Roll each into a ball.
4. Heat a cast iron pan or comal to medium-high heat (around 400 degrees F). No oil.
5. Roll each ball into a thin disc, about 6 to 8 inches wide. The thinner you roll, the more bubbly the finished tortilla.
6. Cook on the dry hot pan for 45 to 60 seconds per side. The tortilla should puff up in places. Don’t overcook; you want a few small brown spots, not a uniform brown.
7. Stack and cover with a clean kitchen towel to keep them soft.
Three Variations Worth Trying
1. Whole Wheat Sourdough Tortillas
Replace 100 g of the all-purpose flour with whole wheat. Add 10 g extra water (whole wheat absorbs more). Same procedure, slightly more fiber and a more rustic flavor. Slightly less elastic; roll gently.
2. Spelt Sourdough Tortillas
Spelt hydrates faster than modern wheat. Use 30 percent less starter (35 g instead of 50 g) and a 15 minute shorter fermentation. The result is nuttier and more tender. Great with grilled vegetables.
3. Sourdough-Corn Tortillas (Hybrid)
Mix 50/50 masa harina and all-purpose flour. Masa has been nixtamalized (treated with lime) so it does not need the long ferment. Use 50 g active starter or 50 g discard. These are not traditional Mexican tortillas (those use 100 percent masa and no leavening), but they are delicious, pliable, and a good intro to corn- forward sourdough cooking.
Common Mistakes (and Fixes)
1. Tortillas crack when rolled. Hydration is too low or the dough is over-fermented. Add 10 g more water next time, or reduce fermentation by an hour.
2. Tortillas are tough or bready. Too much gluten developed. Roll sooner after fermentation, handle less, and use a longer rest between mixing and rolling.
3. Tortillas stick to the pan. Pan is not hot enough. Wait until a drop of water flicked onto the pan sizzles and evaporates within 2 seconds.
4. Tortillas are dry and crumbly. Over-baked or not enough oil. Each tortilla should be on the pan for under 90 seconds per side. Brushing the just-cooked tortilla with a thin layer of oil keeps it soft.
Top Picks (2026)
Best Pan: A Comal (or Cast Iron Skillet)
Cast Iron Comal 9 inch on Amazon
Price: $30 to $50. A comal is a flat cast iron griddle, the traditional Mexican tool for tortillas. Heats evenly, no hot spots. A 9 or 10 inch round fits the standard tortilla size. If you do not have one, a 10 inch cast iron skillet works.
Best Tortilla Press (for consistent thickness)
Cast Iron Tortilla Press on Amazon
Price: $20 to $35. Optional but the most consistent thickness for thin, even tortillas. A rolling pin works but the press is faster. Cast iron is heavy; the aluminum ones are lighter and cheaper.
Best Flour
King Arthur Bread Flour on Amazon
Price: $5 to $7 for 5 lb. For 100 percent flour tortillas use any bread flour. For the corn hybrid use 50 percent masa harina (Maseca brand is widely available).

Sourdough Tortillas FAQ
How long do sourdough tortillas keep?
3 to 4 days at room temperature in a sealed bag, or up to 2 weeks in the fridge. Reheat on a dry pan for 15 seconds per side. They reheat better than flour tortillas because the long ferment keeps them flexible.
Can I use discard starter from the fridge?
Yes, this is the best use of discard. Unfed starter straight from the fridge gives a milder flavor and denser texture, but it is still much better than a standard flour tortilla. The recipes above work either way.
Do I need a tortilla press?
No. A rolling pin works fine, especially if you let the dough balls rest 10 minutes after portioning. A press just makes the job faster and the thickness more consistent.
Can I make these gluten-free?
Not really. Sourdough fermentation needs wheat gluten to develop structure. For gluten-free tortillas, use 100 percent masa harina without leavening (traditional Mexican method). They are excellent but are a different recipe entirely.
