America's Test Kitchen Gluten-Free Bread Recipe: Light, Airy Loaf With No Compromises

America's Test Kitchen gluten-free bread recipe delivers the light, airy texture you crave without the crumbly compromise—proven to rise like traditional bread with the right technique. The secret lies in a precise blend of gluten-free flours and careful hydration adjustments that create structure without gluten.

After years of testing, this method consistently produces a loaf with a crisp crust and tender crumb that holds up to slicing.

What sets this recipe apart is its foolproof approach for home bakers, requiring no special equipment beyond a standard loaf pan. The blend of rice flour, tapioca starch, and xanthan gum mimics gluten's elasticity, while a slow fermentation allows the dough to develop flavor and rise properly.

I've perfected the timing so you won't spend hours waiting—just plan for a 24-hour cold proof that transforms into a golden loaf in 45 minutes of baking.

The result is a gluten-free bread that's restaurant-quality at home—perfect for sandwiches, toast, or serving alongside soups. Each slice maintains its shape without falling apart, and the flavor stays fresh for days when stored properly.

This isn't just another gluten-free loaf; it's the real deal with none of the usual compromises.

Whether you're baking for dietary needs or simply love great bread, this recipe delivers consistent results every time. The key steps—proper mixing, accurate hydration, and controlled baking—are all explained in detail to ensure your first attempt succeeds. Let's get started on a loaf that will impress even gluten-free skeptics.

Ingredients for america's test kitchen gluten free bread

Precision flour blends and hydration science create this restaurant-quality gluten-free loaf without crumbly compromises.

The rice flour and tapioca starch blend is non-negotiable for achieving that traditional bread texture. Bob's Red Mill carries the finest quality rice flour, and always opt for the granular tapioca starch—it dissolves better than the powdered form. Xanthan gum must be pure; Bob's Red Mill or Anthony's Goods are reliable brands. The yeast should be fresh—test by dropping a pinch in warm water; if it foams within 5 minutes, it's active. For the butter, Plugrá or Land O'Lakes unsalted are excellent choices, but any high-fat content butter works. The apple cider vinegar adds subtle tang and improves the gluten-free structure—don't substitute with white vinegar, as the flavor will be too harsh.

No rice flour? Substitute with a 1:1 blend of sorghum flour and potato starch, though texture may vary slightly. Running short on tapioca starch? Arrowroot powder works at the same ratio, but it lacks the same binding properties. Egg substitutes? Flax eggs (2 tbsp ground flax + 6 tbsp water per egg) maintain structure, though texture may be slightly denser. The sesame seeds are optional but add beautiful contrast to the crust—Trader Joe's sells them at a reasonable price. For the water, filtered is best, as tap water with strong chlorine can inhibit yeast activity. If your loaf pan isn't nonstick, use cornmeal for dusting—it prevents sticking better than flour in gluten-free baking.

This dough requires a 24-hour cold proof in the refrigerator for optimal flavor development and rise. Once baked, let the loaf cool completely on a wire rack before slicing—this prevents gummy texture. Store wrapped tightly at room temperature for 3 days, or freeze for up to 3 months by wrapping individual slices in parchment paper. For reheating, 30 seconds at 350°F restores freshness. The bread freezes beautifully, making it ideal for batch baking—portion into single slices before freezing for easy grab-and-go toast.

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

This method delivers a light, airy gluten-free loaf with professional texture and structure.

In a large mixing bowl, whisk together the 1.5 cups white rice flour and 0.5 cup tapioca starch until completely combined. Add the 0.5 teaspoon xanthan gum and whisk again to ensure even distribution. This blend creates the foundation for our gluten-free structure, where the tapioca starch provides elasticity while the white rice flour contributes to a tender crumb.

In a separate small bowl, dissolve the 1 teaspoon instant yeast and 0.5 teaspoon granulated sugar in the 1 cup warm water (about 110°F). The water should be warm enough to activate the yeast but not hot enough to kill it—think slightly warmer than bathwater. Let this mixture sit for 5 minutes until frothy. This step ensures proper yeast activation before mixing with the dry ingredients.

In the same large bowl with the flour blend, add the 2 whole large eggs, 0.25 cup cold unsalted butter (cubed), 1.5 teaspoons salt, and the yeast-sugar mixture. Using a wooden spoon or dough whisk, stir vigorously for 3-4 minutes until the mixture comes together into a shaggy dough. The butter should be incorporated but still visible as small flecks—this prevents the final bread from becoming greasy.

Add the 1 tablespoon apple cider vinegar and continue mixing for another 2 minutes. The vinegar enhances gluten-free structure by mimicking the protein interactions found in wheat flour. The dough will be sticky but should hold together when pressed gently. If it's too wet, add 1 tablespoon more white rice flour; if too dry, add 1 teaspoon warm water. The ideal consistency is thick but pourable.

Lightly grease a 9x5-inch loaf pan with butter or nonstick spray, then dust the bottom and sides with 1 tablespoon cornmeal. This prevents sticking and creates a crisp bottom crust. Transfer the dough to the prepared pan, spreading it evenly with a wet spatula. Cover the pan tightly with plastic wrap and let rise at room temperature for 1 hour, or until the dough has visibly increased in volume by about 50%.

Here's the thing—gluten-free dough rises differently than wheat-based dough. You'll see the edges pull away slightly from the pan's sides, and the surface may develop small bubbles. Don't over-rise it; the dough should remain soft and jiggly when gently pressed. If using a digital scale, aim for a 25-30% volume increase as your visual cue.

Preheat your oven to 375°F. Remove the dough from the pan and place it on a lightly floured surface (use additional 1 tablespoon white rice flour if needed). Gently shape the dough into a smooth, rectangular loaf about 1 inch thick. Place it back in the prepared loaf pan, seam-side up, and cover again with plastic wrap. Let it rise for another 30-45 minutes at room temperature until it expands slightly and feels springy to the touch.

This second rise ensures even baking and prevents a dense crumb. The dough should feel slightly resistant when pressed with your finger—like pressing a ripe avocado pit. If the dough collapses during this rise, it's a sign the yeast may have been overworked or the environment was too warm. In that case, proceed to baking immediately without waiting for full expansion.

Bake the loaf for 35-40 minutes until the top is deep golden brown and an instant-read thermometer inserted into the center reads 205-210°F. The bread should sound hollow when tapped on the bottom. During the last 10 minutes of baking, sprinkle the 1 tablespoon sesame seeds evenly over the top for added texture and visual appeal.

Real talk: The first 15 minutes are critical. If the oven runs hot, the bread may brown too quickly before fully baking inside. If this happens, loosely cover the loaf with aluminum foil to prevent over-browning while allowing steam to escape. The internal temperature is more important than the external color—don't rely solely on visual cues.

Remove the bread from the oven and transfer it to a wire rack to cool completely for at least 2 hours before slicing. This resting period allows the internal structure to set properly, preventing a gummy texture. The bread will continue to firm up as it cools, developing that satisfying crust-to-crumb ratio we're after.

Once fully cooled, slice the loaf into ¼-inch thick pieces using a sharp serrated knife. Each slice should have a crisp exterior with a tender, airy interior—no dense or crumbly bits. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for longer storage. For best results, toast slices before serving to enhance the crust's crunch.

Storing and reheating your leftovers

Room Temperature Storage

Store your gluten-free bread in an airtight container at room temperature for up to 3 days to maintain freshness. I recommend using a glass loaf pan with a tight-fitting lid—it preserves moisture better than plastic.

Wrap the loaf in parchment paper before sealing to prevent drying. For extra crispiness, place a slice of bread in the freezer for 5 minutes before serving to revive the crust. 🌾

Refrigerator Preservation

If you need to extend freshness beyond 3 days, refrigerate the bread in the same airtight container for up to 5 days. The cold slows down staling, but gluten-free bread loses moisture faster than wheat-based bread.

To reheat, wrap a slice in a damp paper towel and microwave for 15-20 seconds at 50% power. For best texture, toast refrigerated slices in a toaster oven at 375°F for 3-4 minutes to restore crispness. ⏰

Freezing for Long-Term Use

Freeze your gluten-free bread in individual slices wrapped tightly in plastic wrap and placed in a freezer bag for up to 3 months. This prevents freezer burn and makes it easy to grab single servings.

To thaw, leave slices out at room temperature for 30 minutes or reheat directly from frozen in the toaster oven at 350°F for 5-6 minutes. For sandwiches, toast directly from frozen—no thawing required! ❄️

Reviving Stale Bread

Gluten-free bread dries out faster than traditional bread, but you can revive it with a quick steam treatment. Place the stale loaf on a baking sheet, cover with a damp kitchen towel, and microwave for 20-30 seconds.

For oven revival, bake at 350°F for 5 minutes with a small bowl of water on the lower rack to create steam. This method works best for 1-2 day old bread when the texture starts to degrade. 💫

Portioning for Convenience

Slice your loaf into ¼-inch thick portions before storing to maintain even texture. Store slices in a single layer in an airtight container with parchment paper between them to prevent sticking.

For quick breakfasts, freeze individual slices in ziplock bags—just remove one when you need it. This method keeps the bread fresh longer and makes toast prep effortless. ✨

Special Considerations

Gluten-free bread benefits from short-term storage rather than long-term. After 5 days, even refrigerated bread loses its ideal texture. For maximum freshness, bake in smaller batches (like 2-3 slices at a time) and freeze immediately.

When reheating, always use low heat to avoid drying out the crumb—high heat turns gluten-free bread rubbery. 🔥
