Introduction
When I first experimented with gluten free sourdough cornbread, I was nervous. Southern-style cornbread without gluten? And with tangy sourdough discard? But I’d been playing with my granny’s cornbread recipes for a few years, and this tweak made all the difference. That irresistible balance of sweet corn, slight tang, and tender crumb—now entirely gluten-free—felt like reclaiming a childhood favorite, just healthier.

Ingredients of gluten free sourdough cornbread
Sourdough Discard – Use discard from a mature gluten-free sourdough starter. Its tangy depth adds complexity without the need for extra leavening.
Gluten-Free Flour – A quality all-purpose gluten-free flour blend works best. I use my nightshade-free blend with consistent results.
Xanthan Gum – Essential for structure if your flour blend doesn’t already include it. Omit if it does.
Cornmeal – Opt for a medium to fine grind for smooth texture. Coarse cornmeal can be pulsed in a food processor for better consistency.
Sugar – A small amount of granulated sugar enhances flavor without making the bread overly sweet.
Baking Powder – Aluminum-free baking powder is a must. I recommend Rumford for a clean taste.
Salt – Fine sea salt evenly seasons the batter and balances sweetness.
Milk – Whole milk at room temperature gives the best richness. See dairy-free substitutions below.
Oil – Avocado oil is my go-to, but any neutral oil like canola or vegetable works beautifully.
Egg – One large egg binds everything. For egg-free, use a flax egg or your trusted baking alternative.
Baking & Serving Gluten Free Sourdough Cornbread
Once your batter is prepped, it’s time to turn that golden goodness into a warm, rustic slice of comfort. This gluten free sourdough cornbread bakes up quickly—just 20 to 24 minutes—and fills your kitchen with a cozy, corn-sweet aroma.

Baking Technique for the Perfect Crumb
Start by preheating your oven to 400°F and greasing an 8×8 square baking pan. You can use nonstick spray or a pat of grass-fed butter for added flavor. Pour your batter in, gently smoothing the top with a spatula so it bakes evenly.
I’ve found the sweet spot is 22 minutes in a standard oven, but check around the 20-minute mark. A toothpick should come out clean from the center, and the edges will start to pull gently away from the sides—signs it’s ready. The crust should be lightly golden, with a soft top that springs back when touched.
Serving Ideas & Storage for gluten free sourdough cornbread
Fresh out of the oven, this cornbread is irresistible. I love slicing it warm and serving it with whipped honey butter or a pat of salted butter with a drizzle of raw honey. For a Southern dinner twist, serve it alongside hearty stews or a bowl of gluten-free chili.
Got leftovers? Wrap them tightly and store at room temp for up to 2 days or refrigerate for up to 5. Reheat slices in the oven at 300°F for about 5 minutes to refresh the texture.
You can also freeze slices individually—wrap in parchment then a freezer bag. To enjoy, just thaw at room temp and reheat gently.

Substitutions, Troubleshooting, and Expert Tips for gluten free sourdough cornbread Recipe
Flour & Milk Substitutions
Prefer dairy-free? Swap whole milk for unsweetened almond, oat, or coconut milk—room temperature for smooth batter. If your gluten-free flour blend doesn’t contain xanthan gum, 1 teaspoon is essential to mimic the texture of traditional cornbread. For a grain-free twist, try cassava-based flour blends mixed 50/50 with cornmeal—just note the crumb will be denser.
Sourdough Discard Tips
Use discard from a mature, gluten-free sourdough starter—ideally refreshed within the past 12 hours. If yours tastes particularly sour or is heavy, stir it gently before measuring to ensure even distribution. For a more pronounced tang, let the batter rest 10 minutes before baking—the flavor will subtly deepen without affecting rise.
Common Troubleshooting Scenarios
- Dense or gummy crumb: Could be from overmixing. Mix just until dry streaks disappear. Ensure baking powder is fresh—expired powder can cause a flat bake.
- Dry edges or crumb: Your oven may run hot; next time, reduce heat to 375 °F and bake a bit longer. Also, check your cornmeal—coarse grind absorbs more liquid.
- Too sour: Use less discard (¾ cup instead of 1 cup) or reduce rest time if letting the batter sit.
Enhancements & Flavor Twists
- Add ½ cup shredded cheddar or pepper jack for a savory kick.
- Fold in 1/4 cup chopped jalapeños or corn kernels for texture and flavor.
- Finish hot cornbread with a sprinkle of flaky sea salt or a brush of melted butter right out of the oven for extra shine.
