What is Sourdough Discard?

If you're new to sourdough baking, "discard" refers to the portion of your sourdough starter that you remove before feeding it again. It’s not waste—it’s a culinary goldmine! This inactive starter still holds great flavor and can be added to a variety of recipes.

Using it in quesadillas allows us to make a pourable batter (like a thin pancake) that becomes your tortilla base. No kneading, rising, or fermenting needed—just pour, cook, and fill with your favorite cheesy goodness.

Ingredients

Here’s what you’ll need to make sourdough discard quesadillas:

For the Tortilla Batter:

• 1 cup sourdough discard (100% hydration)

• 1 egg

• 2 tablespoons milk or water (to thin the batter)

• 1 tablespoon oil (olive or avocado oil work well)

• Pinch of salt

For the Filling (customizable!):

• 1 cup shredded cheese (cheddar, Monterey Jack, mozzarella, etc.)

• Optional add-ins:

  • Cooked chicken or ground beef

  • Sautéed mushrooms

  • Spinach or kale

  • Jalapeños

  • Caramelized onions

  • Refried beans

  • Fresh tomatoes or avocado (added after cooking)

Tools You’ll Need

• Mixing bowl

• Nonstick skillet or griddle

• Spatula

• Measuring cups and spoons

• Ladle or scoop for pouring batter

Step-by-Step Instructions

Let’s walk through every step of making these golden, crispy sourdough quesadillas. They’re easy, forgiving, and endlessly customizable.

Step 1: Make the Batter

In a medium bowl, whisk together your sourdough discard, egg, milk (or water), oil, and a pinch of salt until smooth. You’re aiming for a pourable consistency—like a thin pancake batter. If your batter is too thick, add a little more milk or water to thin it out.

Step 2: Heat the Pan

Place your skillet or griddle over medium heat and add a small amount of oil. Let it heat up for a minute until the oil shimmers.

Step 3: Pour and Cook the "Tortilla"

Pour a ladleful of batter into the skillet and swirl it into a thin circle, like making a crepe. Cook for 2–3 minutes on the first side, until bubbles form and the edges look dry. Flip carefully and cook for another 1–2 minutes on the second side. Transfer to a plate.

Repeat with the remaining batter—you should get 3–4 tortillas depending on size.

Step 4: Add the Filling

Once your tortillas are done, return one to the pan over medium-low heat. Sprinkle cheese over half, then layer on your favorite fillings. Fold the tortilla over to form a half-moon shape.

Cover the pan with a lid and cook for 2–3 minutes, until the cheese is melted and the bottom is golden brown. Flip and cook the other side for another minute or so.

Step 5: Serve & Devour

Slice into wedges and serve hot. Add sour cream, salsa, guacamole, or hot sauce on the side if you’re feeling fancy. Trust me—these go fast!

Tips for Success

• Thin batter = crispier edges. Don’t be afraid to add a bit more liquid if needed.

• Use nonstick or well-oiled pans for easy flipping and golden crusts.

• Don’t overstuff your quesadillas—too much filling makes them hard to flip.

• Let them rest for 1–2 minutes before cutting for melty, clean slices.

Flavor Variations

This recipe is super versatile. Here are some creative combos to try:

• Southwest Style – Cheddar, black beans, corn, and avocado

• Breakfast Quesadilla – Scrambled eggs, bacon, and cheese

• Veggie Deluxe – Mushrooms, spinach, peppers, mozzarella

• Pizza Quesadilla – Marinara, pepperoni, and mozzarella

• BBQ Chicken – Shredded chicken, BBQ sauce, smoked cheddar

Why Sourdough Discard Works So Well

The acidity in sourdough discard helps develop flavor and enhances browning—so your quesadillas will have that beautiful golden crust and a slight tang that makes them irresistibly good. Plus, you’re cutting food waste and stretching your sourdough starter in creative ways.

This recipe is especially great if you’re trying to feed your family or impress guests without spending hours in the kitchen. Everyone loves melty cheese and crisp edges!

Frequently Asked Questions

Can I make these gluten-free?

If your starter is made from a gluten-free flour (like rice, buckwheat, or sorghum), absolutely. Just be sure your fillings are also gluten-free.

Can I refrigerate the batter?

Yes! Store the batter in an airtight container for up to 2 days. Stir before using.

Can I freeze the tortillas?

Definitely. Cook the discard tortillas, cool completely, and freeze between layers of parchment. Reheat in a skillet or toaster oven.

What if I don’t have cheese?

No problem—try mashed beans, sautéed mushrooms, or even hummus for a dairy-free version.

Final Thoughts

Sourdough discard quesadillas are the kind of recipe that makes you feel like a kitchen wizard. You take something that might’ve gone to waste, mix it with a few pantry staples, and turn it into something golden, crispy, cheesy, and deeply satisfying.

No two batches have to be the same—try new fillings, switch up the cheese, or add a spicy drizzle. Make it your own. And don’t forget to make extra—they disappear fast!
