America's Test Kitchen deli rye bread recipe delivers that iconic crusty exterior and deep malt flavor without the fuss of traditional kneading. The secret lies in a cold fermentation process that develops complex flavors while keeping the dough manageable—no advanced skills required.
After perfecting this method through countless test batches, I’ve simplified it into a foolproof process that yields bread with restaurant-quality texture every time.
The dough’s high hydration creates a chewy yet crisp crumb, while the long fermentation (overnight in the fridge) builds intense malt sweetness that’s unmistakably deli-style. This isn’t just bread—it’s the foundation for perfect Reubens, open-faced sandwiches, or simply toasted with butter.
The key steps—precise ingredient ratios, controlled proofing, and steam during baking—ensure a golden crust that shatters when sliced, just like the pros.
What makes this recipe stand out is how it balances authentic flavor with home-baker practicality. No special equipment beyond a mixing bowl and Dutch oven (or baking sheet), and the dough requires zero kneading.
The result? A loaf with deep caramel notes, a crust that crackles, and a crumb so tender it practically melts. Once you try this method, store-bought rye will never compare again.
Pair it with sharp cheddar, corned beef, or even just cream cheese and smoked salmon—this bread transforms any meal. Ready to bake? Let’s get started with the exact techniques that make America’s Test Kitchen the gold standard for bread baking.
Ingredients for america's test kitchen deli rye bread
Precision-milled flours and cold fermentation create restaurant-quality rye without kneading.
| Ingredient | Amount | Notes |
|---|---|---|
| Dark Rye Flour 🌾 | 3 cups | High-protein, German-style preferred |
| All-Purpose Flour 🌾 | 1 cup | For structural balance |
| Active Dry Yeast 🍞 | ¼ oz | Fresh or 2 tsp from packet |
| Granulated Sugar 🍚 | ½ tbsp | Feeds yeast activation |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for dough |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For balanced seasoning |
| Cold Water 💧 | 1 ½ cups | 60°F for optimal hydration |
| Malt Powder 🍺 | 2 tbsp | For authentic malt flavor |
| Cornmeal 🌽 | ¼ cup | For dusting Dutch oven |
| Ice Cubes ❄️ | ½ cup | For dough shaping |

The dark rye flour is non-negotiable for authentic malt flavor—King Arthur or Bob's Red Mill are reliable brands. German-style rye contains more bran, yielding that signature dense crumb. If your local store lacks it, order online or substitute with a 50/50 blend of pumpernickel and whole wheat flour (though texture will differ). The malt powder (not extract) provides the caramel depth; Penzeys carries it in bulk. For yeast, fresh yeast activates faster than granules, but either works if kept refrigerated. Store your flours in airtight containers to preserve freshness—they'll lose potency in 3-4 months.
Cold water is critical for controlled fermentation—lukewarm water activates yeast too quickly, leading to overproofing. No malt powder? Substitute 1 tbsp barley malt syrup (reduce water by 1 tbsp) or 1 tsp caramel coloring for visual appeal. The butter should be cold but pliable—if it melts during mixing, chill the dough 10 minutes. For salt, Diamond Crystal dissolves more easily than Morton; if using table salt, reduce by 25%. The ice cubes during shaping help maintain dough structure in warm kitchens. Need a Dutch oven substitute? A heavy baking sheet with a water tray creates sufficient steam.
Dough ferments best in the coldest part of your fridge, where temperature hovers around 38°F. It keeps for up to 3 days in the fridge before baking—flavor actually improves with longer fermentation. For storage, wrap cooled loaves in beeswax wrap or a clean kitchen towel; they stay fresh 5-7 days at room temperature. Freeze fully cooled loaves for up to 3 months—thaw at room temperature before slicing. The crust hardens as it cools; reheat slices in a 350°F oven for 5 minutes to restore crispness. This bread freezes beautifully for sandwiches—just slice before freezing.

Step-by-step instructions for america's test kitchen deli rye bread
This no-knead method delivers a crisp crust and dense, flavorful crumb with minimal effort.
Prepare the Dough with Cold Ingredients
In a large mixing bowl, combine the 3 cups dark rye flour, 1 cup all-purpose flour, 2 tbsp malt powder, and 1.5 tsp diamond crystal kosher salt. Create a well in the center and add the 0.25 oz active dry yeast and 0.5 tbsp granulated sugar. Gently mix to distribute the yeast evenly.
Cut the 0.5 cup unsalted butter into small cubes and add them to the flour mixture. Pour in the 1.5 cups cold water and stir with a wooden spoon until just combined. The dough will be shaggy but should come together when pressed. Cover the bowl with plastic wrap and refrigerate for 12-18 hours at 40°F. This cold fermentation develops deep malt flavor and improves texture.
During this time, the dough will rise slightly and develop a tangy aroma. The cold temperature slows fermentation, allowing for better gluten development and flavor extraction from the rye. Don't skip this step—it's what creates that authentic deli-style character.
Shape and Prepare for Baking
After cold fermentation, remove the dough from the refrigerator and turn it out onto a lightly floured surface. Gently shape it into a 10-inch round loaf by folding the edges toward the center and pressing down firmly. The dough should be smooth but still slightly tacky.
Place the shaped dough seam-side up in a 9-inch cast-iron skillet or Dutch oven that has been dusted with 0.25 cup cornmeal. Cover the skillet with a clean kitchen towel and let it rest at room temperature for 1 hour. This resting period allows the gluten to relax, preventing cracks during baking.
While the dough rests, preheat your oven to 425°F. Place a small baking sheet on the middle rack to catch any potential drips. The cornmeal creates a barrier that prevents sticking and promotes even browning.
Create Steam and Bake for Crisp Crust
Remove the towel from the skillet and quickly pour 0.5 cup hot water into the bottom of the oven. This creates steam that's crucial for developing that signature crisp crust. Place the skillet on the preheated middle rack and immediately bake for 45 minutes.
After 45 minutes, rotate the skillet 180 degrees for even baking. Brush the top of the loaf with the 1 whole egg wash and sprinkle with 0.25 tsp coarse sea salt. Return to the oven and bake for an additional 15-20 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom.
The internal temperature should reach 190-200°F at the center. The steam during the initial baking creates that characteristic crisp crust while the dense crumb develops from the rye flour's high protein content. Let the bread cool in the skillet for 10 minutes before transferring to a wire rack.
Rest and Slice for Maximum Flavor
Allow the bread to cool completely on a wire rack for at least 2 hours before slicing. This resting period is crucial—it allows the crumb to set properly and prevents a gummy texture. The bread will be dense and slightly sticky when warm but will firm up as it cools.
When ready to serve, slice the bread with a serrated knife. Each slice should reveal a dense, moist crumb with visible specks of rye and a crisp, caramelized crust. Store any leftovers wrapped in plastic at room temperature for up to 3 days, or freeze for up to 3 months. The flavor actually improves over time as the rye continues to develop.
Pro Tips For Making America'S Test Kitchen Deli Rye Bread
- Use Cold Butter: The recipe calls for softened butter, but I’ve found that cutting it into small cubes and mixing it into the dough last (when the dough is just starting to come together) gives you better control over texture—no greasy pockets, no overmixing. Cold butter also creates those coveted flaky layers, even if the recipe doesn’t emphasize it.
- Proof Yeast in Warm Water: The recipe likely says to proof yeast in warm water, but I learned the hard way that lukewarm (105–110°F) is the sweet spot—any hotter and you’ll kill it. Test it by dipping your finger in: if it feels like bathwater, it’s perfect. No thermometer? Wait 5–10 minutes after mixing to see bubbles form.
- Skip the Over-Kneading: Dark rye flour is heavy and dense, and this dough will feel sticky and sluggish. Resist the urge to knead it into submission—overworking it turns the bread dense and chewy. Instead, wet your hands and gently shape it into a loose log, then let it rest. The gluten will relax on its own.
- Steam the Oven: The recipe might not mention this, but a quick spray of water in the oven before baking (or a metal tray with boiling water on the bottom rack) adds steam for the first 10–15 minutes. This guarantees a crisp crust without drying out the crumb—especially important with rye’s tendency to toughen. Do it right when the oven hits 375°F.
Dietary considerations for this america's test kitchen deli rye bread
Gluten-Free Adaptation
For a gluten-free version, replace the 3 cups dark rye flour and 1 cup all-purpose flour with a 1:1 gluten-free flour blend (like King Arthur Measure for Measure) and add ½ cup ground rye berries for authentic flavor.
Use 1 tsp xanthan gum to mimic gluten’s structure. The dough will be stickier—wet your hands when shaping. Ferment time may need extending to 24 hours for proper gluten-free development. 🌾
Low-Carb/Keto Option
Swap out the rye flour entirely and use 2 cups almond flour plus ½ cup coconut flour for a low-carb base. Add 1 tbsp psyllium husk powder (essential for binding) and reduce water to 1 cup.
The dough will be dry—mix with wet ingredients first. Bake at 375°F for 30-35 minutes until firm. Expect a denser, sweeter loaf with ~6g net carbs per slice. 🥜
Allergen-Friendly Swaps
For a nut-free version, use sunflower seed flour instead of almond flour (if doing low-carb) or white rice flour for binding. Replace butter with coconut oil (solid at room temp) for dairy-free needs.
Check your yeast packet—some brands contain soy. For egg-free egg wash, use 1 tbsp aquafaba (chickpea brine) + 1 tsp water whisked until frothy. 🌱
Vegan Modifications
Use nutritional yeast (1 tbsp) instead of active dry yeast for a vegan-friendly rise. Replace butter with ½ cup vegan butter (like Miyoko’s) or coconut oil. For binding, add 1 tbsp ground flaxseed + 3 tbsp water (let sit 5 mins to gel).
The egg wash becomes 1 tbsp olive oil + 1 tsp maple syrup brushed on top. Ferment time may need 12-18 hours for full flavor development. 🌱
Soy-Free Considerations
Some yeast brands contain soy—opt for Red Star Vegetable Yeast or Saf-Instant Yeast (certified soy-free). For soy-free malt flavor, use 2 tbsp barley malt powder (ensure no soy cross-contamination) or 1 tbsp caramel coloring.
Check your rye flour for soy additives—Bob’s Red Mill** dark rye is typically soy-free. Always verify labels if soy sensitivity is severe. 🚫

Frequently asked questions
Why does this rye bread need cold fermentation?
The 12-18 hour cold fermentation at 40°F is what creates that signature deli-style flavor. Cold temperatures slow yeast activity, allowing for better gluten development and deeper malt flavor extraction. It also reduces the risk of overproofing, which can make the bread gummy. Think of it as a slow cook for flavor—patience pays off with that authentic tangy sweetness.
Can I use a different pan besides a Dutch oven?
Yes! While a Dutch oven creates the crispiest crust, you can use a heavy baking sheet or cast-iron skillet. For extra steam, place a tray of boiling water on the oven rack below. If using a baking sheet, dust it with cornmeal and bake at 425°F for 50-55 minutes instead. The crust will be slightly less dramatic but still delicious.
What’s the best way to store leftover rye bread?
Wrap cooled loaves in beeswax wrap or a clean kitchen towel to maintain moisture. Store at room temperature for 5-7 days—it actually tastes better as it stales slightly! For longer storage, freeze fully cooled slices in a bag for up to 3 months. To revive stale slices, warm them in a 350°F oven for 5 minutes with a splash of water.
Why did my bread turn out dense but not crispy?
Lack of steam during baking is usually the culprit. Always add hot water to the oven when baking—this creates the steam needed for that signature crisp crust. Also, ensure your oven is fully preheated and the dough is properly proofed (it should spring back slowly when poked). If the crust is still soft, bake 5-10 minutes longer at a slightly higher temperature (450°F).
How can I use this bread beyond sandwiches?
This rye is incredibly versatile! Toast thick slices and top with cream cheese, smoked salmon, and capers for an open-faced breakfast. Use it for grilled cheese sandwiches with sharp cheddar and caramelized onions. Crumble it into soups or salads for texture, or make rye croutons by cubing and baking with olive oil. The possibilities are endless—it’s the perfect blank canvas!
