America's Test Kitchen rye bread recipe delivers the perfect balance of crusty exterior and malty, dense crumb that bakes up like a professional artisan loaf—without requiring years of experience.
The secret lies in precise hydration control and a fermentation process that develops deep flavor while creating that signature open crumb structure. I've tested countless variations, and this method consistently produces a loaf with a dark, crackly crust and a moist yet sturdy interior that holds up to slicing.
What makes this recipe work is the combination of traditional techniques with modern shortcuts: we use a small amount of commercial yeast alongside a simple sourdough starter to jumpstart fermentation, then let the dough develop its complexity over 12 hours at room temperature.
The starter adds tangy depth while keeping the process manageable for home bakers. For those short on time, a 24-hour cold fermentation in the refrigerator produces equally impressive results with less active monitoring.
The baking process itself is where the magic happens—steaming the oven creates that signature crisp crust while maintaining moisture in the crumb. With proper scoring and baking times, you'll achieve an open crumb structure and caramelized crust that rivals any bakery loaf.
This recipe builds confidence by providing clear troubleshooting tips for common issues like dense texture or uneven rise, ensuring your first attempt will be successful.
Perfect for sandwiches, toast, or serving alongside soups, this rye bread develops even better flavor over the next few days as the starches convert to sugars. The method scales easily for larger batches, making it ideal for meal prep or gifting. Let's get started on creating your perfect loaf.
Ingredients for america's test kitchen rye bread
This rye bread recipe transforms simple pantry staples into a bakery-style loaf with a crackly crust and malty crumb.
| Ingredient | Amount | Notes |
|---|---|---|
| Bread Flour 🌾 | 4 cups | High-protein for structure |
| Dark Rye Flour 🌾 | 1 ½ cups | Pumpernickel for malty depth |
| Active Dry Yeast 🍞 | ¼ tsp | Freshly opened for potency |
| Sourdough Starter 🍞 | ½ cup | Active, bubbly starter |
| Light Brown Sugar 🍯 | ¼ cup | Packed for accurate measure |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Cold Water 💧 | 2 ½ cups | Chilled for proper hydration |
| Malt Powder 🌾 | 1 tbsp | Enhances flavor development |
| Instant Vital Wheat Gluten 🌾 | 1 tbsp | For improved crumb structure |
| Cornmeal 🌽 | ½ cup | For dusting and scoring |
| Ice Water ❄️ | ¼ cup | For final dough adjustment |
| Coarse Sea Salt 🧂 | 1 tsp | For crust enhancement |
| Rice Flour 🌾 | 1 tbsp | For scoring contrast |
The flours are the heart of this recipe—bread flour for structure and dark rye flour for that signature tang. King Arthur or Cape Cod bread flour work best, while Bob's Red Mill pumpernickel delivers the deepest flavor. If you can only find light rye flour, add an extra 1/4 cup molasses to compensate. The yeast and starter combo is non-negotiable: fresh yeast (not the foil packets) and an active starter with bubbles—10% hydration works perfectly. For the malt powder, Briess is my go-to, but any malt extract powder will do. The vital wheat gluten is crucial for that open crumb structure—don't skip it!
No sourdough starter? 1/2 cup buttermilk plus 1/2 tsp baking soda mimics the acidity, though it won't develop the same complexity. Running short on dark rye flour? Substitute half with whole wheat flour—it'll be lighter but still delicious. The cornmeal is for scoring, but if you're out, semolina works just as well. For the scoring contrast, rice flour creates those beautiful white lines against the dark crust. Pro tip: toast your own malt powder by dry-toasting in a pan for 2 minutes—it deepens the caramel notes. And always measure your flour by weight if possible for consistency, but if you're using cups, spoon and level for accuracy.
This dough is a patience game—12 hours at room temp or 24 hours cold for maximum flavor. Store your starter in the fridge between uses (it'll last weeks), and keep your flours in airtight containers to prevent weevils. The baked loaf develops even better flavor over 3-4 days as the sugars caramelize. For leftovers, wrap tightly in parchment and foil—it'll stay fresh for 5 days or freeze for 3 months. The crust gets crispier with time, so plan ahead if you're making it for a special occasion.

Step-by-step instructions for america's test kitchen rye bread recipe
This method delivers a rye bread with an irresistible crusty exterior and a dense, malty crumb that rivals artisanal bakeries.
Mix the Dough for Optimal Hydration
In a large mixing bowl, combine the 4 cups bread flour, 1.5 cups dark rye flour, 1 tbsp malt powder, and 1 tbsp instant vital wheat gluten. This high-protein blend creates the perfect structure for that signature rye density. Create a well in the center and add the 0.25 tsp active dry yeast, 0.5 cup sourdough starter, 0.25 cup light brown sugar, and 1.5 tsp salt. The sugar and starter will activate the yeast while the malt powder enhances the rye's characteristic flavor.
Gradually add the 2.5 cups cold water while mixing with a wooden spoon until a shaggy dough forms. The cold water ensures proper gluten development without overactivating the yeast. Cover the bowl with a damp kitchen towel and let it rest for 15 minutes. This initial rest allows the flour to fully hydrate and the gluten to begin forming. You'll notice the dough becomes slightly more cohesive and easier to handle.
Develop the Gluten Through Kneading
Transfer the rested dough to a lightly floured surface and knead for 8-10 minutes by hand, or use a stand mixer with a dough hook attachment on medium speed for 5-6 minutes. You're aiming for a smooth, elastic dough that springs back slowly when poked. The combination of bread flour and vital wheat gluten creates a chewy yet sturdy texture that holds up beautifully to slicing.
During kneading, the gluten strands align to trap gas produced by the yeast, which is essential for that open crumb structure. If the dough feels too sticky, add 1 tablespoon of bread flour at a time until it becomes manageable. The dark rye flour contributes to the dough's stickiness, so don't be surprised if it requires a bit more flour than typical bread doughs. The goal is a dough that's smooth but still slightly tacky to the touch.
Bulk Fermentation for Flavor Development
Shape the dough into a loose round and place it back in the mixing bowl. Cover with the damp towel and let it ferment at room temperature (70-72°F) for 1.5-2 hours. You'll know it's ready when the dough has nearly doubled in size and shows 25-30% overrise. The sourdough starter and yeast work together during this time, creating complex flavors and developing the bread's signature tang.
Gently punch down the dough every 30 minutes during fermentation to redistribute the yeast and prevent large air pockets. This step also helps strengthen the gluten structure further. The cold water from the initial mix slows fermentation slightly, giving you more control over the timing. If your kitchen is cooler, extend the fermentation time by 30 minutes to allow for proper development.
Shape and Final Proof
Turn the dough out onto a lightly floured surface and divide it into 4 equal portions (about 12 ounces each). Shape each portion into a round boule by pulling the dough toward you in a circular motion while rotating the dough. The tension created during shaping helps develop the crust. Place the shaped loaves seam-side up on a baking sheet dusted with 0.5 cup cornmeal. The cornmeal prevents sticking and adds a subtle flavor contrast.
Cover the loaves loosely with plastic wrap and let them proof at room temperature for 30-45 minutes until they've risen 50-75%. The final proof is crucial for that open crumb structure. Just before baking, brush each loaf with 0.25 cup ice water and sprinkle with 1 tsp coarse sea salt. The ice water creates steam during baking, promoting oven spring, while the coarse salt enhances the crust's texture and flavor.
Bake for Maximum Crust and Crumb Development
Preheat your oven to 425°F with a baking stone or inverted baking sheet on the lower rack. Place the loaves on the stone or sheet and bake for 25-30 minutes. The high heat creates that signature crisp crust while maintaining a moist, dense crumb. Rotate the pans halfway through baking for even browning.
During the last 5 minutes of baking, score each loaf deeply with a razor blade or sharp knife, dusted with 1 tbsp rice flour for contrast. The scoring prevents over-expansion and creates those beautiful, crispy ridges. The bread is done when it reaches an internal temperature of 190-195°F and sounds hollow when tapped on the bottom. Transfer to a wire rack to cool completely before slicing—this allows the steam to escape and the crumb to set properly.
Pro Tips For Making America'S Test Kitchen Rye Bread
- WEIGH YOUR FLOURS: The ATK recipe calls for precise ratios—bread flour and dark rye flour need exact measurements. I used to eyeball it, but a digital scale (even a cheap $10 one) eliminates guesswork. That extra 10 grams of rye makes the flavor sing, and skipping this step means your loaf might turn out too dense or sour.
- HYDRATE THE RYE: Dark rye flour absorbs water like a sponge. Mix it with the warm water first, then let it sit for 10 minutes before adding the rest of the ingredients. This prevents a dry, crumbly dough—trust me, I’ve fought that battle.
- DON’T OVER-PUNCH THE DOUGH: The ATK recipe includes a punch-down step after the first rise. I used to think more punching = stronger gluten, but this dough is delicate. Just 2-3 gentle folds with wet hands are enough—overworking it turns the crumb gummy.
- BAKE WITH STEAM: The recipe’s Dutch-oven method works, but for a better oven spring, add a metal tray of boiling water to the rack below. The extra steam keeps the crust from drying out too fast—no need to wait for the oven to preheat fully, just toss in the water when you load the dough.
Common mistakes when making this recipe
Over-Mixing the Dough
Rye bread dough contains a high percentage of dark rye flour, which makes it naturally sticky and less elastic than wheat-based doughs. Over-kneading develops too much gluten, resulting in a tough, dense crumb instead of the desired open, malty texture.
I recommend kneading by hand for 8-10 minutes or using a stand mixer on medium speed for 5-6 minutes—just until the dough becomes smooth and slightly tacky. Stop when it springs back slowly when poked, not when it's firm and elastic like white bread dough. 💡
Skipping the Rest Period
The 15-minute rest after mixing is crucial for proper hydration and gluten formation. Without it, the dough becomes unevenly mixed, leading to inconsistent texture and poor oven spring. During this time, the flour fully absorbs the water, and the gluten begins to relax.
I've seen home bakers rush this step, only to end up with a dense loaf that lacks the signature open crumb structure. Trust the process—this brief rest makes all the difference. ⏱️
Incorrect Fermentation Conditions
Fermentation is where the magic happens, but temperature control is key. If your kitchen is too warm (above 75°F), the yeast will over-activate, causing the dough to rise too quickly with weak structure.
Conversely, if it's too cool (below 68°F), fermentation slows dramatically, leading to underdeveloped flavor and poor rise. I keep my dough at 70-72°F using a proofing box or by placing it near the oven with the light on.
For colder kitchens, extend fermentation by 30-60 minutes rather than increasing temperature. 🌡️
Underestimating Hydration Needs
Rye dough requires precise hydration—too little water results in a dry, crumbly loaf, while too much creates a gummy mess. The recipe calls for 2.5 cups cold water for this ratio of flours, but dark rye flour absorbs moisture differently than bread flour.
If your dough feels too stiff after mixing, add 1 tablespoon of water at a time until it reaches a shaggy consistency. The cold water is essential—it prevents premature yeast activation while allowing proper gluten development during the initial rest. 💧
Improper Shaping Technique
Shaping creates tension in the dough that contributes to oven spring and crust development. When shaping rye boules, pull the dough toward you in a circular motion while rotating the boule to create even tension. Many beginners handle the dough too gently, resulting in weak structure and poor rise.
I like to use a bench scraper to help create clean edges and prevent sticking. The seam should face up in the pan to prevent cracking during baking. 🧤
Baking Without Steam
The steam generated during baking is what creates that signature crisp crust and open crumb. Without it, your loaf will develop a pale, dry crust instead of the deep, crackly exterior you want.
I achieve steam by placing a baking stone on the lower oven rack and adding 1 cup boiling water to a tray on the middle rack when the oven reaches temperature. For the last 5 minutes, I also spray the oven walls with water for extra steam.
This technique makes all the difference in crust texture. 🌫️

Frequently asked questions
Why does this rye bread recipe use both yeast and sourdough starter?
The combination creates the perfect balance: commercial yeast provides reliable, predictable rise while the sourdough starter adds depth and complexity. The starter contributes natural acidity and tang that enhances the rye's malty flavor, while the yeast ensures consistent results even for beginners. This hybrid approach delivers professional-quality flavor without requiring years of starter maintenance.
Can I make this rye bread without a sourdough starter?
Yes! Substitute the ½ cup sourdough starter with ½ cup buttermilk plus ½ tsp baking soda to mimic the acidity. For best results, use ½ cup molasses instead of the brown sugar to compensate for the missing rye depth. The flavor won't be identical, but you'll still get a delicious loaf with proper structure. The starter is ideal, but this substitution works in a pinch.
How do I know when the dough is properly fermented?
Look for 25-30% overrise—when the dough has nearly doubled in size with visible bubbles and a slightly domed shape. Press your finger gently into the dough: if it springs back slowly (like Jell-O), it's ready. For rye dough, fermentation should take 1.5-2 hours at 70-72°F. If your kitchen is cooler, extend by 30-60 minutes. Over-fermented dough collapses when baked, while under-fermented dough won't rise properly.
What's the best way to store leftover rye bread?
Wrap the cooled loaf tightly in parchment paper followed by plastic wrap to preserve moisture. Store at room temperature for 3-4 days—the flavor actually improves as starches convert to sugars! For longer storage, freeze the bread (unsliced) for up to 3 months. To revive, toast frozen slices directly from the freezer. The crust gets crispier with time, so plan ahead for maximum flavor.
Can I adjust this recipe for a smaller batch?
Yes, but maintain the same flour ratios. For a 2-loaf batch, reduce all ingredients by half (including water). Keep the starter at ¼ cup and yeast at ¼ tsp. Use a 9x5-inch loaf pan for one loaf or shape into two boules. The hydration ratio (water to flour) is critical—don't reduce water proportionally. A smaller batch ferments faster, so monitor closely for 1-1.5 hours total.
