Transforming sourdough discard into crispy, golden focaccia is my favorite way to turn baking scraps into a showstopping side dish. This recipe proves that what you might toss can become something extraordinary—no waste, all flavor.
The secret lies in capturing that tangy, airy discard magic while baking it into a pillowy loaf with a shatteringly crisp crust.

The key is stretching the dough thin, dimpling it with your fingers, and baking until the crust turns golden and crispy while the inside stays soft and airy.
Imagine pulling this focaccia from the oven—warm, fragrant, and crackling with every bite. The crispy crust gives way to tender, chewy pockets, all infused with that signature sourdough tang. It’s the kind of dish that makes your kitchen smell like a Mediterranean bakery and leaves everyone asking for seconds.
Perfect for brunch, appetizers, or alongside soups, this focaccia proves you don’t need fancy ingredients to create something impressive. Let’s turn your discard into dinner!
Ingredients for sourdough discard
Turn discard into golden focaccia with these simple, zero-waste ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Sourdough Discard 🍞 | 1 cup | Unfed, active discard (100% hydration) |
| All-Purpose Flour 🌾 | 2 cups | Plus extra for dusting |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Water 💧 | ½ cup | Room temperature |
| Salt 🧂 | 1 ½ tsp | Fine sea salt preferred |
| Active Dry Yeast 🍞 | ¼ tsp | Or 1 tbsp instant yeast |
| Maple Syrup 🍁 | 1 tbsp | For subtle sweetness |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, optional |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, optional |
| Flaky Sea Salt 🧂 | 2 tsp | For final sprinkle |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Nutritional Yeast 🧀 | 1 tbsp | For cheesy flavor (optional) |
The discard is your secret weapon. Use active, bubbly discard—if it’s not bubbling, feed it with 1 tbsp flour and 1 tbsp water 4-6 hours ahead. Whole Foods or Trader Joe’s sell discard if you don’t bake sourdough, but I always have a jar stashed in my fridge. The flour matters too—King Arthur or Caputo Tipo 00 give the best texture, but all-purpose works in a pinch. For the olive oil, California Avocado Ranch or Colavita brands add that fruity punch that makes focaccia taste like a bakery. Fresh herbs? Costco sells rosemary and thyme bundles that last weeks in the freezer.
No yeast? Skip it—this focaccia relies on discard’s natural leavening. Short on maple syrup? Agave or a pinch of sugar works just as well. The nutritional yeast adds a cheesy note without dairy—Bragg or Bob’s Red Mill are the best brands. For extra crispiness, brush the dough with more olive oil before baking. Want to stretch the recipe? Double everything—just make sure your baking sheet is extra large. The flaky sea salt is key for that gourmet touch. Maldon or Jacobsen are my go-tos, but any flaky salt works. Prefer a different herb? Fresh oregano or basil both shine here.
This focaccia keeps best at room temperature for 2 days in a bread bag, but it reheats beautifully. Wrap in foil and warm at 350°F for 5-10 minutes to revive that crispy crust. Freeze portions for up to 3 months—wrap tightly in plastic and thaw overnight. I always make a double batch. One for dinner, one for toast the next morning. The leftovers? Perfect for croutons or breadcrumbs. Every bite tastes like you spent hours in the kitchen, but honestly, it’s just 20 minutes of magic.

Step-by-step instructions for crispy focaccia using sourdough discard
Here’s how to transform your discard into golden, crispy focaccia with a chewy interior.
Activate the Sourdough Discard
In a medium bowl, combine the 1 cup sourdough discard, 0.5 cup water, 0.25 tsp active dry yeast, and 1 tbsp maple syrup. Let it sit at room temperature for 1-2 hours until it doubles in volume and develops a bubbly, slightly tangy aroma. You’ll know it’s ready when the mixture looks foamy and has expanded noticeably.
This activation step is crucial—it ensures your yeast is alive and ready to work. If your discard is very active, it might double faster. If it’s sluggish, give it an extra 30 minutes in a warm spot. The maple syrup here adds subtle sweetness while feeding the yeast for better rise.
Mix the Dough and Incorporate Herbs
In a large mixing bowl, whisk together the 2 cups all-purpose flour, 1.5 tsp salt, 0.25 tsp black pepper, and 1 tbsp nutritional yeast. Create a well in the center and pour in the activated discard mixture. Stir with a wooden spoon until just combined—you’ll still see some dry flour spots, which is perfect for that signature focaccia texture.
Next, gently fold in the 1 tbsp fresh rosemary and 1 tbsp fresh thyme using your hands. The herbs should be finely distributed but still visible—this ensures flavor without overwhelming the bread. Let the dough rest for 10 minutes while you prepare your baking surface. This brief rest helps the flour absorb the liquid and makes the dough easier to handle.
Shape and Proof the Dough
Lightly flour a work surface and transfer the dough onto it. Gently shape the dough into a 12×8-inch rectangle, about 1-inch thick. For an extra-crispy crust, I like to press down slightly with my fingers to create shallow dimples all over the surface—this gives you those classic focaccia pockets while promoting even browning.
Transfer the shaped dough to a parchment-lined baking sheet. Cover loosely with a clean kitchen towel and let it proof at room temperature for 1-2 hours until it has risen noticeably and feels slightly springy to the touch. The edges should pull away from the sides of the pan, but don’t let it proof too long or it may collapse when baking.
Add Olive Oil and Final Seasoning
Preheat your oven to 425°F while the dough proofs. Once the dough has risen, generously drizzle the 0.5 cup extra-virgin olive oil over the surface, letting it pool in the dimples. Use your fingers to spread the oil evenly, pressing down gently to create more pockets. Sprinkle with 2 tsp flaky sea salt and press it lightly into the dough.
This step is where the magic happens—the olive oil creates that signature glossy crust while preventing the focaccia from drying out. The flaky sea salt will melt slightly during baking, creating beautiful salt crystals on the surface. Bake for 20-25 minutes until the crust is deep golden brown and crispy, and the internal temperature reaches 190°F when measured with an instant-read thermometer.
Cool and Serve for Maximum Crispiness
Remove the focaccia from the oven and let it cool on the baking sheet for 5 minutes before transferring to a wire rack. This brief cooling period allows the crust to set properly while preventing it from becoming soggy. The focaccia should be crispy on the outside with a soft, airy interior that pulls apart easily.
Serve warm with additional flaky sea salt and a drizzle of extra-virgin olive oil. The contrast between the crispy crust and tender interior makes every bite satisfying. For best results, enjoy within 2-3 hours of baking when the crust is at its peak crispiness. Store leftovers wrapped in a clean towel to maintain texture.
Pro Tips For Making Sourdough Discard
- WEIGH YOUR DISCARD: That jar of discard? Don’t eyeball it—use a scale for accuracy. A 1:1:1 ratio (discard:flour:water) works best, but if your starter’s active, lean toward 1:1.5:1 (less water) to avoid a gummy mess. I learned this the hard way when my first batch turned into a sad, sticky puddle.
- STIR IN THE OIL: Add the olive oil after mixing flour and water—it’s the only way to get even distribution. Skip this, and you’ll end up with pockets of dry dough that fight back when shaping. A few swirls with a wooden spoon until it looks like wet sand is non-negotiable.
- REST THE DOUGH: Let it sit covered for 30–60 minutes after mixing, even if you’re not making bread. This lets the discard’s wild yeast wake up and hydrate the flour properly. I was skeptical until I tried it—now my discard pancakes and crackers have actual structure instead of collapsing like sad soufflés.
- SALT THE WATER: Yes, even for discard recipes. Dissolve the salt in the water first—it’s the only way to control flavor and prevent clumping. I used to add it later and ended up with uneven saltiness, like a bad poker hand. A pinch (½ tsp per cup of water) is enough to make a difference.
Storing and reheating this recipe
Room-Temp Storage
Your freshly baked focaccia stays at its crispy, golden best for 2 days at room temperature when stored properly. I wrap mine in a clean, breathable kitchen towel inside a paper bag—this keeps the crust from becoming rubbery while maintaining that bakery-fresh texture.
Place it in a cool, dark spot like a pantry or countertop away from direct sunlight. The towel prevents condensation, which can make the crust soggy. 🌟
Refrigerator Revival
If you need to store focaccia longer than 2 days, refrigerate it wrapped in foil or plastic for up to 5 days.
To revive that crispy crust, I recommend warming it in the oven at 350°F for 5-10 minutes—just until it smells fragrant and the crust regains its golden color. For a quick fix, pop it in the toaster for 2-3 minutes on medium-high heat.
The interior stays soft while the crust crisps back up beautifully.
Freezer Magic
Freezing is my go-to for long-term storage—this focaccia freezes exceptionally well for up to 3 months without losing quality. Wrap individual portions tightly in plastic wrap, then place them in a freezer bag with all air squeezed out.
When ready to eat, thaw overnight in the fridge or warm directly from frozen in the oven at 375°F for 15-20 minutes, covered with foil for the first 10 minutes to prevent over-browning. The texture remains crispy and chewy, just like fresh.
Reheating Secrets
For microwave reheating, I use the defrost setting for 30-45 seconds—this gently warms the focaccia without turning it into a science experiment. For best results, cover it with a damp paper towel to prevent drying. The oven method always gives the best results, though.
I love preheating my oven to 350°F, placing the focaccia on a baking sheet, and warming it for 8-10 minutes until the crust is golden and the interior is heated through. This method preserves the crispy texture better than any other.
Leftovers Reinvented
Don’t let leftovers go to waste—transform them into something new! Crumble stale focaccia into homemade croutons for salads or soups. Toss it with olive oil, garlic, and herbs, then bake at 375°F for 8-10 minutes until crispy.
Or blend it into breadcrumbs for coating chicken or fish. The focaccia’s flavor adds a delicious depth to any dish. Every bite feels like a culinary win, even when you’re repurposing yesterday’s loaf. 💡

Frequently asked questions
Can I use stale sourdough discard for this recipe?
Fresh, active discard works best for this focaccia. If your discard is over 7 days old or smells overly sour, revive it first by mixing with 1 tbsp flour and 1 tbsp water, then letting it sit at room temperature for 4-6 hours until bubbly. The tangy flavor develops over time, but overly sour discard can overpower the dough’s balance.
What if my focaccia doesn’t rise enough?
Underproofed dough is usually the culprit. Let the dough proof until it’s 50-75% larger and springs back slowly when gently pressed. If your kitchen is cold (65°F or below), place the dough in a warm oven with the light on for 10 minutes to help it rise faster. Never skip proofing—it’s what creates that airy texture!
Can I make this focaccia without yeast?
The sourdough discard contains wild yeast, so you can safely omit the added yeast. For best results, use 1 cup very active discard (with visible bubbles) and let the dough proof for 3-4 hours instead of 1-2 hours. The flavor will be more tangy, which works beautifully with the herbs.
How can I make this focaccia more flavorful?
Boost the flavor by adding 1 tbsp grated garlic to the dough or drizzling 1 tbsp garlic-infused olive oil after baking. For a cheesy twist, sprinkle 1/4 cup grated Parmesan on top before baking. You can also add 1 tsp dried oregano or 1/2 tsp red pepper flakes for extra depth. The possibilities are endless!
Why did my focaccia turn out dense instead of crispy?
Dense focaccia usually means overmixing or underproofing. Handle the dough gently—just until combined—and let it proof until it’s noticeably puffy. Also ensure your oven is fully preheated to 425°F and use a baking sheet, not a glass pan, which can steam the bread. For extra crispiness, brush with more olive oil before baking.
