America's Test Kitchen Gluten-Free Bread Recipe: Foolproof Rise and Crusty Texture

America's Test Kitchen gluten-free bread recipe delivers the same satisfying rise and crispy texture as traditional bread—without the gluten. This method uses precise hydration ratios and xanthan gum to create a light, airy loaf that bakes up golden brown with a satisfying crunch.

After years of testing, we've perfected the balance between structure and tenderness that gluten-free breads often miss.

The key to success lies in proper mixing techniques and controlled fermentation. Unlike many gluten-free recipes that result in dense, dry loaves, this method incorporates a slow fermentation process to develop flavor and improve texture.

We use a blend of gluten-free flours and a precise ratio of xanthan gum to mimic the elasticity of gluten, ensuring your bread rises properly and holds its shape.

What you'll achieve is a bread with a crispy crust that gives way to a soft, airy interior—just like the bread you remember. The recipe includes specific baking instructions to prevent over-browning while ensuring even cooking throughout.

This is gluten-free baking at its best, where you won't sacrifice texture or taste for dietary needs.

Perfect for sandwiches, toast, or serving alongside soups, this bread is designed to be your new gluten-free staple. The method is repeatable, so you can bake a perfect loaf every time without the common pitfalls of dryness or density that plague many gluten-free bread recipes.

Ingredients for america's test kitchen gluten free bread

Gluten-free flours, xanthan gum, and precise hydration create a bread with restaurant-quality texture.

The flour blend is everything—Bob's Red Mill gluten-free flours work perfectly, but avoid blends with added fillers. Tapioca starch gives that signature chew, while potato starch keeps it tender. King Arthur sells a pre-mixed gluten-free flour that's a game-changer if you hate measuring. Xanthan gum is non-negotiable here—it's what makes this bread rise properly. Grab it from the baking aisle or order online if your store doesn't carry it. The yeast should be fresh: if it's been sitting in your pantry for months, test it first by mixing with warm water and sugar—it should foam within 10 minutes.

No xanthan gum? Psyllium husk powder at half the amount works in a pinch, though the texture will differ slightly. Running short on eggs? Flax eggs (1 tbsp ground flax + 3 tbsp water per egg) keep the structure intact. The honey can be swapped for maple syrup or agave, but honey adds that subtle depth. For the olive oil, avocado oil works too—just don't use anything with a strong flavor like walnut oil. The warm water is critical: too hot and you'll kill the yeast, too cold and it won't activate properly. Use a thermometer if you're unsure—105-110°F is perfect.

This dough is sticky—don't panic! Wet your hands when handling it to prevent sticking. Let it ferment at room temperature for 1-2 hours until nearly doubled, then shape and bake. The baked loaf keeps well wrapped at room temperature for 3 days, or freeze slices for up to 3 months. For extra crispiness, brush the crust with melted butter after baking. This bread reheats beautifully: 5 minutes at 350°F restores that fresh-baked aroma.

Step-by-step instructions for america's test kitchen gluten-free bread recipe

This method delivers a golden crust and airy crumb that rivals traditional bread—every time.

In a large mixing bowl, combine the 2 cups white rice flour, 1.5 cups tapioca starch, 0.5 cup potato starch, 0.25 tsp xanthan gum, 0.75 tsp instant yeast, 1 tbsp granulated sugar, and 1.5 tsp salt. Whisk vigorously for 2 minutes until no lumps remain. The xanthan gum will disperse completely, creating the essential gluten-like structure that holds this bread together.

This step is non-negotiable—I've found that even a single lump can create dense pockets in the final loaf. Sift the ingredients if you're concerned about clumping, but whisking works perfectly with these fine-milled flours. Set the bowl aside while you prepare the wet ingredients.

In a separate bowl, gently whisk together the 0.25 cup extra-virgin olive oil, 2 whole large eggs, 1.25 cups warm water (between 105-110°F), 1 tbsp honey, and 1 tbsp granulated sugar. The mixture should be smooth with no visible streaks of oil. Here's the thing—room temperature eggs and oil incorporate better, preventing cold spots that can halt fermentation.

Test the water temperature with your finger—it should feel pleasantly warm but not hot to the touch. If your water is too hot, it will kill the yeast before it has a chance to activate. The olive oil adds richness and helps create that coveted crusty exterior we're after.

Pour the wet ingredients into the dry ingredients bowl and mix with a wooden spoon until just combined. You'll notice the mixture will be thicker than traditional bread dough—this is normal. Let the batter rest for 10 minutes while you prepare your 9x5-inch loaf pan by coating it generously with 2 tbsp cornmeal (tap out any excess).

The resting period allows the xanthan gum to fully hydrate and the starches to begin their work. Don't skip this step—it's what transforms this from a simple batter into a bread with proper structure. The cornmeal coating prevents sticking and gives that beautiful golden crust we're aiming for.

Pour the batter into the prepared loaf pan and smooth the top with a wet spatula. Cover the pan tightly with plastic wrap and let it ferment at 75°F for 1 hour. You're looking for about 30-50% rise—the bread should puff noticeably but not double completely. Here's where the magic happens: the yeast activates just enough to create structure without overproofing, which gluten-free breads are particularly prone to.

I use an instant-read thermometer to verify the water temperature before mixing—this consistency is crucial. If your kitchen is cooler, extend fermentation by 15 minutes. The goal is to develop flavor without compromising texture. After fermentation, the batter should be slightly domed above the pan's edges.

Preheat your oven to 375°F with a baking stone or inverted baking sheet on the middle rack. Place the loaf pan on the stone and bake for 50-55 minutes until the internal temperature reaches 205°F and the top is deep golden brown. For that restaurant-quality crust, pour ½ cup hot water into a small oven-safe dish and place it on the lower rack 5 minutes before baking begins.

The steam creates the ideal environment for crust development while keeping the crumb tender. I check for doneness by tapping the bottom—the bread should sound hollow. If the top browns too quickly, tent loosely with foil after 30 minutes. Remove from the oven and let cool in the pan for 10 minutes before transferring to a wire rack.

Allow the bread to cool completely on the wire rack for at least 2 hours. This resting period is absolutely critical—it allows the starches to fully set and prevents that gummy texture gluten-free breads are notorious for. The longer you wait, the better the texture becomes, but even 1 hour makes a noticeable difference.

Slice with a sharp serrated knife for clean cuts. The interior should be uniformly crumbly with a slight sheen from the olive oil, and each slice should hold its shape without falling apart. Store wrapped at room temperature for 3 days or freeze for up to 3 months—this bread actually improves with age as the starches continue to develop.

Pro cooking tips for perfect results

Xanthan Gum Secrets

The 0.25 tsp xanthan gum is non-negotiable for structure, but measuring it accurately is key. I use a 1/8 tsp measuring spoon from King Arthur Baking—their precision tools make all the difference.

For those without xanthan gum, 0.125 tsp psyllium husk powder works in a pinch, though the texture will be slightly denser. Never omit it entirely—this bread will collapse without it. 🧪

Hydration Control

Gluten-free dough behaves differently, so hydration matters more than in traditional bread. The 1.25 cups warm water should feel like a thick pancake batter—if it's too runny, add 1 tbsp extra rice flour. Too thick? Add 1 tsp water at a time.

I test consistency by lifting the batter with a spoon—it should hold its shape but still be pourable. The 105-110°F water temperature is critical; use an instant-read thermometer to avoid killing the yeast.

Fermentation Precision

Fermenting at 75°F for 1 hour develops flavor without overproofing—this is where most gluten-free breads fail. I use a proofing box (like the Breville Smart Oven Air Fryer) for consistency, but a warm oven with the light on works too.

Look for 30-50% rise—any more and the structure weakens. If your kitchen is cooler, extend fermentation by 15 minutes but no longer, or the bread will taste flat.

Steam for Crust

The ½ cup hot water in the oven creates steam that mimics commercial bakery conditions. Pour it into a small oven-safe dish and place it on the lower rack 5 minutes before baking. This prevents cracking and gives that coveted crispy crust.

For extra insurance, brush the loaf with melted butter after baking—it adds flavor and prevents drying. The bread will continue to crisp up as it cools, so don't rush this step.

Resting Matters

Letting the bread cool 2 hours on a wire rack is the difference between a gummy loaf and restaurant-quality texture. The starches need time to set properly, and slicing too soon creates a crumbly mess.

I store leftover slices in airtight containers with a slice of apple or lemon wedge to keep them fresh longer. For reheating, 5 minutes at 350°F restores that fresh-baked aroma without drying it out.

Equipment Upgrades

Invest in a 9x5-inch loaf pan with high sides (like Nordic Ware) to prevent overflow. A baking stone ensures even heat distribution, while a digital thermometer (I use Thermoworks) guarantees perfect internal temps.

For shaping, wet your hands to prevent sticking—this dough is deceptively sticky! The right tools make all the difference in gluten-free baking, where precision is everything. 💡
