Description
A soft, flavorful gluten-free sandwich bread made using sourdough discard. Perfect for sandwiches, toast, and snacking, this bread combines the tangy depth of sourdough with a tender crumb and gluten-free ingredients.
Ingredients
1 cup gluten-free sourdough discard (unfed)
1 1/2 cups warm water (about 110°F)
2 tablespoons honey
2 teaspoons active dry yeast
3 cups gluten-free all-purpose flour blend (with xanthan gum included)
1/2 cup brown rice flour
1/4 cup tapioca starch
1 teaspoon salt
2 large eggs, room temperature
1/4 cup olive oil
1 teaspoon apple cider vinegar
Instructions
In a large mixing bowl, combine the warm water, honey, and active dry yeast. Stir gently and let it sit for 5-7 minutes until the mixture is foamy.
Add the gluten-free sourdough discard to the yeast mixture and stir to combine.
In a separate bowl, whisk together the gluten-free all-purpose flour blend, brown rice flour, tapioca starch, and salt.
Add the dry ingredients to the wet ingredients in the large mixing bowl.
Add the eggs, olive oil, and apple cider vinegar to the mixture.
Using a stand mixer fitted with a paddle attachment or a hand mixer, mix on medium speed for 3-4 minutes until the dough is smooth and sticky. The dough will be more like a thick batter than traditional bread dough.
Lightly grease a 9×5-inch loaf pan with oil or nonstick spray.
Pour the dough into the prepared loaf pan and smooth the top with a wet spatula.
Cover the pan loosely with plastic wrap or a clean kitchen towel and let the dough rise in a warm place for 45-60 minutes, or until it has risen to about 1 inch above the rim of the pan.
Preheat the oven to 375°F (190°C).
Remove the cover and place the loaf pan in the preheated oven.
Bake for 45-50 minutes until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove the bread from the oven and let it cool in the pan for 10 minutes.
Transfer the bread to a wire rack to cool completely before slicing.

Mastering Gluten-Free Sourdough Discard Sandwich Bread
The Magic Behind the Tangy Softness
This bread isn’t your average loaf—it’s a wild card thanks to that gluten-free sourdough discard. Using discard here does double duty: it injects a punch of tang that’s a nod to classic sourdough but without the wait, and it adds natural acidity that plays beautifully with the yeast, boosting rise and flavor. The sourdough discard, unfed and all, brings an unpredictable little twist that keeps the crumb moist and the texture tender, avoiding the usual rubbery trap many gluten-free breads fall into. I remember the first time I tried baking with discard—it was like giving my bread a secret handshake with sourdough history, except faster and fuss-free.
And here’s the kicker—the mix of flours in this recipe is a carefully crafted trio that balances structure and softness. Brown rice flour lends a nutty backbone, tapioca starch delivers that bounce and chew, and the all-purpose blend (with xanthan gum) holds everything together like glue without the gluten. The eggs and olive oil further enrich the dough, ensuring it stays luscious and doesn’t dry out, even after toasting. It’s not just baking; it’s chemistry with a splash of kitchen magic.
Ingredient Swaps That Won’t Crash the Party
First off—don’t panic if you’re missing a few flours. Brown rice flour? Swap it for sorghum or millet flour to keep the loaf’s integrity intact. Tapioca starch can be replaced with arrowroot powder or cornstarch, but beware—too much arrowroot can make things gummy. For the oil, avocado oil works just as well and adds a subtle richness without overpowering the sourdough notes. And if you’re egg-free? Use flax eggs (1 tablespoon flaxseed meal mixed with 3 tablespoons water per egg) but expect a slightly denser crumb—a small price to pay.
One big heads-up: don’t skimp on the apple cider vinegar. That bit of acid is the unsung hero that helps the dough rise and keeps the crumb tender. Removing it can leave your loaf flat and dry, which no one wants. Think of it as the secret handshake the dough needs to fluff up properly.
When Things Go Sideways—Fixing Common Gluten-Free Fails
Sticky and dense dough? Totally normal here—don’t fight it. Gluten-free batter loaves are more batter than dough, so resist the urge to add extra flour mid-mix; it’ll backfire and dry out your bread.
Rising problems? Check your yeast freshness and water temperature. Yeast loves it warm but not hot—110°F is the sweet spot. Also, rising in a drafty or cold spot will slow things down; use a slightly warmed oven (turned off) to keep it cozy.
Crust too tough or thick? Try tenting the loaf with foil halfway through baking to prevent over-browning. And if your slice crumbles when you cut it, let it cool completely before slicing—cutting warm gluten-free bread is like trying to tame a wild bronco.
Gluten-Free Sourdough Discard Sandwich Bread FAQs
Technically, yes, but you’ll miss that tangy punch and depth the discard brings. The bread will still rise thanks to the yeast, but it won’t have that signature sourdough vibe that makes this recipe unique.
Absolutely. The crumb is soft yet sturdy enough to hold up to your favorite fillings without falling apart. I once piled on avocado, smoked turkey, and a swipe of mustard—no soggy mess, just clean bites.
Yes, but don’t sweat it. Use a gluten-free all-purpose blend that includes xanthan gum. That’s the magic glue here, making sure your bread doesn’t turn into a crumbly disaster.
Yes! Wrap the cooled loaf tightly and stash it in the freezer for up to 3 months. When you’re ready, thaw at room temp or pop slices right into the toaster. Weeknight lifesaver, trust me.
Not exactly. It’s a different beast—gluten-free with a mild tang thanks to the discard. It won’t have the chewy crust or dense crumb of wheat sourdough, but it nails the flavor twist and softness, which is a win in my book.
