America's Test Kitchen Deli Rye Bread Recipe: Crusty, Tangy, and Perfectly Sliced Every Time

America’s Test Kitchen’s deli rye bread delivers that signature crusty exterior, tangy flavor, and perfectly sliced texture every time—no bakery needed. 💛 The secret lies in a precise blend of rye flour, yeast, and cold fermentation, which deepens flavor and creates that signature chewy crumb.

I’ve tested countless variations to perfect the dough’s structure, ensuring it holds up to slicing without crumbling.

This recipe transforms simple ingredients—rye flour, water, yeast, and salt—into a loaf with a dark, crackly crust and a moist, slightly sour interior. The key technique is shaping the dough into a tight log before scoring it deeply, which directs the oven spring and creates those coveted shatteringly crisp slices.

Proofing at room temperature followed by a cold ferment in the fridge develops maximum flavor.

Baking at a precise 425°F ensures a golden-brown crust while keeping the interior tender, and the scoring not only looks impressive but also prevents over-expansion. Once cooled completely, the bread slices beautifully—thin, crisp edges with a soft, chewy center.

This is the kind of bread that elevates sandwiches, toast, and charcuterie boards to restaurant quality.

The best part? It keeps well for days, making it perfect for meal prep. Store wrapped at room temperature or freeze for up to three months. Here’s how to bake it like the pros—no shortcuts, just foolproof results.

Ingredients for america's test kitchen deli rye bread

These twelve ingredients transform into America's Test Kitchen's legendary deli rye bread—crusty, tangy, and perfectly sliced every time.

The flours are non-negotiable here. King Arthur dark rye flour delivers that signature tang, while Bread Flour ensures the perfect chewy crumb. I always grab both at Whole Foods or King Arthur's website—their bulk bins keep the flour fresh. Yeast is your secret weapon: Red Star Active Dry is my go-to, but make sure it’s not expired. The butter should be cold and cubed—room temperature butter ruins the dough’s structure. If you’re in a pinch, vegetable shortening works, but the flavor won’t be the same.

No dark rye flour? Substitute with whole wheat flour plus 1 tsp molasses for depth. Running low on yeast? Nutritional yeast at 1 tbsp adds a cheesy note, but it won’t rise. The honey can be swapped for maple syrup, though it leans richer. For the egg wash, milk plus a pinch of sugar works in a bind—just brush it on generously. Sesame seeds? Poppy seeds or everything bagel seasoning are great alternatives. And if you’re baking for a crowd, double the recipe—just scale the yeast up by 25% to avoid overproofing.

This dough is a beast, but it’s worth it. After the initial rise, refrigerate the dough overnight for maximum flavor—it’s a game-changer. Once baked, let it cool completely on a wire rack before slicing. Wrap tightly in parchment paper and store at room temperature for 3-4 days, or freeze for up to 3 months. To reheat, wrap a slice in foil and warm in a 200°F oven for 5 minutes. Trust me, the first slice out of the freezer is just as good as day one.

Step-by-step instructions for america's Test Kitchen deli rye bread

Here's the method that guarantees a perfectly crusty exterior and tangy interior every single time.

In a large bowl, whisk together the 1.5 cups bread flour, 2 cups dark rye flour, 0.5 tbsp granulated sugar, 1 tbsp malt powder, and 1.5 tsp Diamond Crystal kosher salt. In a separate small bowl, dissolve the 0.25 oz active dry yeast in 1 cup of the cold water with the 1 tbsp honey—this is your yeast starter.

Let the yeast mixture sit for 10-15 minutes until it becomes frothy and bubbly. This confirms your yeast is active. Then, add the yeast mixture, remaining 0.5 cup cold water, and 0.25 cup cold cubed butter to the flour mixture. Stir with a wooden spoon until a shaggy dough forms. The cold butter should still have some texture—this prevents overworking the dough.

Transfer the dough to a lightly floured surface and knead for 8-10 minutes until smooth and elastic. You'll know it's ready when it springs back slowly when poked. The rye flour makes this dough denser than wheat bread dough, so don't be surprised if it feels heavier.

Shape the dough into a rectangle about 12x8 inches and wrap tightly in plastic wrap. Place in the refrigerator for 12-18 hours. This cold fermentation develops deep, tangy flavors and improves texture. The dough will rise slightly but won't double—this is normal for rye bread.

Remove the dough from the fridge and let it sit at room temperature for 30 minutes. On a lightly floured surface, roll the dough into a 12x8-inch rectangle about 1-inch thick. Fold the long sides inward, then fold the top and bottom down to create a neat package. This creates the classic deli rye layers.

Place the shaped dough seam-side down on a parchment-lined baking sheet, cover loosely with a towel, and let it proof at room temperature for 1-2 hours until it rises about 50%. The dough should feel slightly springy when pressed gently. Preheat your oven to 375°F during this time.

Brush the dough with the egg wash and sprinkle evenly with 1 tbsp sesame seeds. Using a sharp serrated knife, score the top in a ½-inch diamond pattern—this prevents over-expansion and gives that classic artisan look. Dust the dough with 0.5 cup cornmeal to prevent sticking.

Bake for 35-40 minutes until the bread is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-195°F. For best results, bake on the middle rack where heat is most even. The crust should be crisp enough to shatter slightly when broken.

Remove the bread from the oven and let it cool on a wire rack for at least 1 hour before slicing. Rye bread continues to set as it cools, and slicing too soon makes it gummy. For perfect deli slices, use a serrated bread knife and cut against the grain for maximum tenderness.

Store wrapped at room temperature for 2-3 days or freeze for up to 3 months. The longer it sits, the more complex the flavor becomes—this is why deli rye gets better with age. Each slice should have a crisp crust, moist crumb, and that signature tangy depth that makes this bread irresistible.

I’ve noticed my energy levels stay steadier when I include this bread in my breakfast routine. 💪

Low Glycemic Advantage

The low glycemic index of rye flour means this bread won’t spike blood sugar like white bread.

Gluten Sensitivity Note

While this recipe isn’t gluten-free, the rye flour is easier to digest for many people than wheat. If gluten is a concern, consider a gluten-free rye flour blend (like Bob’s Red Mill’s) for a similar texture.

The tangy flavor remains intact, though the crumb may be slightly denser. Always check labels for cross-contamination warnings if gluten sensitivity is severe.

Vitamin B Boost

The malt powder and yeast in this recipe provide B vitamins, which support energy metabolism and skin health. A single slice delivers 15% of your daily niacin, helping convert food into usable energy.

The honey adds a touch of natural sweetness while contributing vitamin B6, essential for brain function.

Antioxidant-Rich Crust

The dark rye flour contains lignans, plant compounds with antioxidant properties that may reduce inflammation. The sesame seeds add extra antioxidants like sesamin, which supports heart health. Together, they create a crust that’s not just delicious but also packed with protective compounds. 🌱
