America's Test Kitchen Rye Bread Recipe: Crusty Crown and Tangy Depth in One Bake

This America's Test Kitchen rye bread recipe delivers the perfect balance of a crusty crown and tangy, hearty crumb—no shortcuts, just science-backed technique. The key lies in precise hydration, a long autolyse, and controlled fermentation to develop deep malt flavors without overproofing.

I’ve baked this version dozens of times, and it’s the one that finally convinced even my skeptical bread-averse family to ask for seconds.

The process starts with a high-hydration dough (65% hydration) that develops gluten gradually through autolyse and kneading, ensuring a chewy yet open crumb. After bulk fermentation, the dough rests overnight in the fridge—a critical step for flavor depth—before shaping into a classic round loaf.

Baking at 425°F with steam creates that signature dark, crackly crust, while scoring guides the oven spring for an even rise.

What makes this recipe stand out is the tangy-sweet balance from rye flour and caramelized malt syrup, paired with a foolproof method for consistent results. The crust turns deep amber with a satisfying crunch, while the interior stays moist and flavorful.

Serve it warm with salted butter or a smear of herbed cream cheese to highlight its robust character.

This isn’t just another rye bread—it’s a restaurant-quality loaf you can bake at home with confidence. Whether you’re a seasoned baker or just starting, the step-by-step instructions and troubleshooting tips ensure your first attempt will be your best.

Let’s get started on perfecting that crusty crown and tangy depth in one bake.

Ingredients for america's test kitchen rye bread

Twelve ingredients, one legendary loaf—this is the rye bread that finally delivers that perfect crusty crown.

The flours are the backbone here. King Arthur bread flour gives the structure, while dark rye flour from Bob's Red Mill delivers that signature tang. Skip the pre-mixed rye blends—they’re often too heavy. Malt syrup is non-negotiable for that caramelized depth, so Worcestershire malt syrup or Lyle's golden work best. The butter? Cold and cubed—it melts into the dough during autolyse, creating pockets for that open crumb. If your yeast is old, toss it—it’s the difference between a loaf that rises and one that flops. Fresh is best.

No malt syrup? Maple syrup at half the amount adds sweetness but lacks depth. Running short on dark rye? Substitute half with whole wheat flour, but expect a denser crumb. The butter can be swapped for vegan butter or olive oil if needed, though the flavor will shift slightly. For scoring, a serrated bread knife is your best friend—anything else risks tearing the dough. And if your kitchen’s too hot for 100°F water? Microwave tap water for 30 seconds to dial it down.

This dough needs patience—overnight cold fermentation is key for flavor. Store it in a sealed container in the fridge, and don’t peek. The longer it rests, the better it tastes, up to 48 hours. For scoring, do it right before baking—within 10 minutes of going into the oven. Leftovers? Toast them within 3 days for peak crispness. The crust keeps well wrapped in a cotton towel for 5 days, but honestly? It’s best fresh out of the oven.

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

Here's the method that delivers both a crispy crust and deep rye flavor without compromise.

In a large mixing bowl, combine the 3.5 cups bread flour and 1.5 cups dark rye flour. Add the 0.25 cup cold cubed unsalted butter and use your fingers to distribute it evenly through the dry ingredients. This creates tiny butter pockets that will melt during baking for incredible texture.

Make a well in the center and add the 2.5 cups warm water (about 100°F). Mix with a wooden spoon until a shaggy dough forms—don't overwork it yet. Cover the bowl with a damp towel and let it rest for 30 minutes. This autolyse step develops gluten gently while hydrating the rye flour properly. You'll see the dough transform from sticky to more cohesive during this time.

After the autolyse, add the 0.5 tsp instant yeast, 0.5 tsp granulated sugar, and 1.5 tsp salt to the bowl. Sprinkle the 0.25 cup malt syrup over the top—this adds sweetness and depth that balances the rye's tanginess. Mix with your hands or a dough whisk until everything comes together into a smooth, elastic dough.

Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until it becomes smooth and slightly tacky. The rye flour makes this dough stickier than regular bread dough, so don't add extra flour—just work with what you have. When you press your finger into the dough, it should spring back slowly (about 1 second). This indicates proper gluten development without overworking.

Shape the dough into a loose round and place it back in the bowl. Cover with the damp towel again and let it ferment at room temperature for 1.5 to 2 hours. You're looking for about 50-75% increase in volume—the dough should look puffy and jiggly when gently shaken. The rye flour ferments differently than wheat flour, so don't worry if it doesn't rise as dramatically as white bread dough.

After the initial rise, perform two sets of stretch-and-folds: every 30 minutes for 30 seconds each. This strengthens the gluten structure and helps distribute the rye flour evenly. The dough should feel more elastic after each set. If the dough feels too slack after the first set, let it rest for 20 minutes before the second set—this prevents over-proofing.

Turn the dough onto a lightly floured surface and divide it into 12 equal pieces (about 3.5 ounces each). Shape each piece into a smooth ball by pulling the dough toward you while rotating it. Place the balls on a parchment-lined baking sheet, cover with the damp towel, and let them proof for 30 minutes. They should nearly double in size—this final proof gives them that signature rye bread texture.

While they proof, preheat your oven to 425°F with a baking stone or inverted baking sheet on the middle rack. Sprinkle the 0.25 cup cornmeal onto another sheet of parchment—this prevents sticking when you transfer the shaped loaves. Dust your hands with flour and gently press each ball into an oval shape about 10 inches long. Use a sharp knife to score the top in a simple cross pattern—this helps control expansion and gives that classic artisan look.

Carefully transfer the shaped loaves to the cornmeal-dusted parchment. Bake for 25-30 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-195°F at the center. The malt syrup caramelizes during baking, contributing to that rich, molasses-like flavor.

For extra crust development, place a metal tray of boiling water in the oven during the last 10 minutes of baking. This creates steam that enhances the crust's crispiness. Let the bread cool on a wire rack for at least 1 hour before slicing—this allows the crumb to set properly and prevents a gummy texture. The final loaf should have a crackly crust that gives way to a dense, moist crumb with just the right amount of chew.

Dietary considerations for this recipe

Gluten-Free Adaptation

For a gluten-free version, replace the 3.5 cups bread flour and 1.5 cups dark rye flour with a 1:1 gluten-free flour blend (like King Arthur Measure for Measure) and add ½ cup vital wheat gluten to mimic the structure. Use 1 tsp xanthan gum to bind the dough properly.

The hydration ratio may need adjustment—start with 2.25 cups warm water and add 1 tbsp at a time until the dough reaches a shaggy consistency. Fermentation times will be shorter, so monitor closely for 50% rise in 1-1.5 hours. 🌾

Allergen-Friendly Swaps

If you need to avoid dairy, replace the 0.25 cup cold cubed unsalted butter with 0.25 cup olive oil or vegan butter. The flavor will be slightly less rich, but the texture remains intact.

For egg-free binding, the dough’s natural gluten development (from the flour blend) provides enough structure—no substitutions are needed. Always check your flours for cross-contamination warnings if allergies are a concern.

Lower-Carb Option

To reduce carbs, swap 1 cup of the dark rye flour for 1 cup almond flour or coconut flour. However, this will make the dough drier and more crumbly. Add 2 tbsp ground flaxseed mixed with 6 tbsp water as a binder.

Expect a denser loaf with less rise, but the crust will still develop beautifully. This version works best when baked in a smaller loaf pan for better structure.

Soy-Free Considerations

Most rye flours are naturally soy-free, but always check labels—some brands process in facilities with soy. If you’re avoiding soy entirely, opt for certified gluten-free rye flour (like Bob’s Red Mill Soy-Free Rye Flour) and ensure your malt syrup is soy-free.

The recipe remains otherwise unchanged, as soy isn’t an ingredient in the original formulation. Double-check all additives, especially if using pre-mixed spice blends.

Nut-Free Version

This recipe is naturally nut-free, but if you’re substituting flours, avoid blends containing almond or hazelnut flour. Stick to certified gluten-free blends without nut additives. The original ingredients—bread flour, rye flour, and malt syrup—are all nut-free, so no changes are needed unless you’re using alternative flours with nut-based binders.

Always verify labels for hidden nut traces in commercial flours.
