If you maintain a sourdough starter, you know the struggle: regular feedings create more discard than you can reasonably use. Sourdough flour tortillas are a brilliant solution that transforms that excess starter into delicious, tangy flatbreads perfect for tacos, wraps, or simply enjoying warm from the pan. Unlike yeasted tortillas, these develop subtle sour notes and require no overnight fermentation, making them an ideal weeknight project.
How to Make Sourdough Flour Tortillas
This recipe uses either active sourdough starter or discard–both produce excellent results. The dough comes together quickly and rests while you prepare your cooking surface.
Ingredients
- 1 cup sourdough starter (discard or active starter, room temperature)
- 2 cups all-purpose or bread flour
- 3/4 teaspoon salt
- 2 tablespoons fat (neutral oil, melted butter, or lard)
- 2-4 tablespoons warm water (only if needed to reach proper consistency)
Method
Combine wet ingredients
Pour your sourdough starter into a large mixing bowl. Add the fat and stir together until the fat is loosely incorporated. The mixture doesn’t need to be fully homogeneous at this stage.
Mix in dry ingredients
Sprinkle the flour and salt over the wet mixture. Using a wooden spoon or your hand, mix until shaggy dough forms. You may need to add 1-2 tablespoons of warm water if the dough seems too dry, but aim for a texture slightly drier than typical bread dough.
Knead the dough
Transfer the dough to your work surface and knead for 5-8 minutes until the mixture becomes smooth and elastic. The dough should feel slightly tacky but not sticky. This develops enough gluten structure for tender tortillas.
Rest the dough
Form the dough into a ball, lightly coat it with a touch of oil, and place it in a covered bowl. Let it rest for 20-30 minutes at room temperature. This allows the flour to fully hydrate and makes the dough easier to work with.
Divide and shape
Turn the rested dough onto your work surface and divide it into 8-10 equal portions. Roll each portion into a ball, then flatten slightly. Cover the balls loosely with a damp cloth while you work through them to prevent drying.
Roll thin
Working with one dough ball at a time, use a rolling pin to flatten it into a thin circle, about 1/8 inch thick. The thinner you roll, the more pliable the tortilla will be. Aim for circles roughly 7-8 inches across.
Cook on high heat
Heat a heavy skillet or griddle over medium-high to high heat until very hot. Place one rolled tortilla on the surface and cook for 30-45 seconds until light brown spots appear, then flip. Cook the second side for another 30-45 seconds until the tortilla puffs slightly. Repeat with remaining dough.
Serve warm
Transfer cooked tortillas to a plate and stack them under a clean kitchen towel to keep them warm and soft. Serve immediately with your favorite fillings or simply with butter and salt.
- Discard starter works just as well as active starter for this recipe–you don’t need to time your baking around peak fermentation.
- If your tortillas don’t puff during cooking, your pan may not be hot enough. A properly preheated surface is essential for the characteristic slight separation between layers.
- Cooked tortillas freeze beautifully for up to 2 weeks. Reheat wrapped in foil in a 300-degree oven for 10 minutes to restore softness.
Essential Equipment for Making Sourdough Tortillas
- Heavy skillet or cast iron griddle: The primary cooking surface must retain heat consistently and reach high temperatures quickly. Cast iron is ideal for even heat distribution and long-term durability, though heavy stainless steel works well too.
- Rolling pin and work surface: You need a smooth, clean surface for rolling dough and a tool to flatten it evenly. Marble, wood, or silicone surfaces all work; avoid surfaces that are too sticky or uneven.
- Mixing bowls: Start with at least one large bowl for combining ingredients and allowing the dough to rest. Glass or ceramic bowls make it easy to see dough development and prevent unwanted reactions.
- Kitchen scale (optional but helpful): While measurements by volume work fine, a scale ensures consistency batch to batch and helps you divide dough into truly equal portions for uniform tortillas.

Frequently Asked Questions
Can I use sourdough discard that hasn’t been fed recently?
Yes, the beauty of this recipe is that it works with either recently-fed starter or older discard. The leavening power matters less than the flavor and hydration the starter provides. Even discard that’s been sitting in your fridge for weeks will produce delicious tortillas.
Why aren’t my tortillas puffing up during cooking?
Puffing requires high, consistent heat. Make sure your skillet or griddle is fully preheated and hot enough that a drop of water sizzles immediately. If the pan isn’t hot enough, the tortilla will brown before steam builds up to create the characteristic puff.
How should I store leftover tortillas?
Wrap cooled tortillas in a clean kitchen towel or store them in a paper towel-lined container at room temperature for up to two days. For longer storage, stack them between parchment sheets in a freezer bag for up to three weeks, then reheat in a dry skillet or wrapped in foil in a warm oven.
Do I need to add yeast to this recipe?
No, the sourdough starter provides all the leavening needed. The fermentation from the starter plus the steam created during cooking gives you tender, slightly risen tortillas without any commercial yeast.
Can I make the dough ahead and cook the tortillas later?
Absolutely. After the initial 20-30 minute rest, you can refrigerate the dough for up to 12 hours. Bring it back to room temperature before rolling and cooking, or cook directly from the fridge–just allow a few extra minutes for the dough to warm and relax.
