About this Recipe

This recipe turns sourdough discard into soft, pliable tortillas using just four simple ingredients:

• discard
• flour
• salt
• oil

The natural tang from the discard adds flavor while creating tender tortillas that can be made in under 30 minutes.

No special equipment needed beyond a rolling pin and skillet.

Why Sourdough Discard Works in Tortillas

Sourdough discard brings a subtle tanginess that makes these tortillas more interesting than your standard flour-and-water version.

The fermentation process has already broken down some of the starches and proteins, which means the dough handles beautifully and the final texture is tender without being fragile.

Unlike bread baking, where you need active starter and hours of rising time, tortillas are one of those instant-gratification discard recipes.

Your discard can be straight from the fridge, unfed and ignored for days. That’s actually ideal here since we’re not relying on it for leavening. We just want that flavor and the moisture content it provides.

The Four Ingredients

• Sourdough Discard (1 cup, 240g) – This is your base. It adds flavor, moisture, and helps create that soft texture. Use discard at any hydration level; I’ve made these with everything from stiff starter discard to very liquid discard, and they all work.
• All-Purpose Flour (1½ to 2 cups, 180-240g) – This gives structure. You’ll add it gradually until the dough comes together. The exact amount depends on how hydrated your discard is.
• Salt (1 teaspoon) – Non-negotiable for flavor. These taste flat without it.
• Oil (2 tablespoons) – I use olive oil or avocado oil. This is what makes the tortillas pliable instead of crispy. Don’t skip it.

How to Make Them

Mix your discard, salt, and oil in a bowl. Add flour gradually, starting with 1½ cups. Stir until it becomes shaggy, then turn it out and knead for about 3-4 minutes. You want a smooth dough that’s soft but not sticky. If it’s sticking to your hands, add more flour a tablespoon at a time.

Let the dough rest for 10-15 minutes. This lets the gluten relax so the tortillas roll out easily. Cover it with a damp towel or plastic wrap so it doesn’t dry out.

Divide the dough into 8 equal pieces (about 60g each). Roll them into balls, then use a rolling pin to flatten each one into a thin circle, roughly 7-8 inches across. Don’t stress about making them perfectly round. Rustic is fine.

Heat a dry skillet (cast iron works great) over medium-high heat. Once it’s hot, add a tortilla. It should start bubbling and puffing within 30 seconds. Cook for about 45-60 seconds on the first side until you see brown spots, flip, and cook another 30-45 seconds. Stack finished tortillas in a kitchen towel to keep them soft.

What to Expect

Your first tortilla might cook too fast or too slow while you dial in the heat. That’s normal. Adjust your burner as needed. You want them to puff and develop brown spots without burning.

The discard flavor is noticeable but not overwhelming. Think of it as a grown-up flour tortilla with a little something extra. They’re sturdy enough for tacos or burritos but tender enough to fold without cracking.

They’ll stay soft for several hours if you keep them wrapped in a towel. For longer storage, let them cool completely, then stack them with parchment paper between each one and store in a zip-top bag in the fridge for up to a week. Reheat in a dry skillet or directly over a gas flame.

Ways to Use Them

These work for anything you’d use a regular flour tortilla for.

Breakfast tacos with scrambled eggs. Lunch wraps with hummus and vegetables. Dinner fajitas. Roll them up with butter and cinnamon sugar for a quick snack. Use them as a vehicle for leftover pulled pork, carnitas, or whatever’s in your fridge.

I’ve also used them as a base for quesadillas and even torn them into chips for chilaquiles. They’re not traditional corn tortillas, so don’t expect that flavor profile, but they hold up well to heat and don’t get soggy quickly.

Why I Keep Making These

I’ve tried a lot of sourdough discard recipes: crackers, pancakes, pizza dough, all of it. Some are great, some feel like make-work projects designed to use up discard but not actually enjoyable to eat. These tortillas fall firmly in the “I’d make these even if I didn’t have discard to use up” category.

They’re fast, which matters on weeknights. They use basic ingredients. And they taste legitimately good, not just good for a discard recipe. That tanginess from the sourdough adds depth that you don’t get with store-bought tortillas, and the texture is soft and pliable in a way that’s hard to achieve without lard or shortening.

Plus, there’s something satisfying about taking something you’d otherwise throw away and turning it into dinner. My starter creates discard constantly, and this is one of the most practical ways I’ve found to use it without feeling like I’m eating discard for the sake of eating discard.
