The best part? It keeps well for days, making it ideal for meal prep or gifting.

Ready in about 24 hours (including fermentation), this recipe is designed for success. The dough is forgiving, the crust is foolproof, and the final loaf will have you questioning why you ever bought store-bought rye. Let's get started on your next perfect loaf.

Ingredients for america's test kitchen deli rye bread

These 13 ingredients transform into bakery-style rye bread with foolproof foil-sealed crust and tangy seed swirls.

The rye flour is non-negotiable—King Arthur or Bob's Red Mill are my go-tos for that deep, earthy flavor. Caraway seeds can be tricky to find, so check the spice aisle at Whole Foods or order online if needed. For the yeast, FreshPaks work best if you want to skip measuring, but active dry yeast is fine if you stick to the scale. The honey should be raw and unfiltered for that authentic tang—Mad Honey or local farm honey are perfect. If you're using a sourdough starter, swap the yeast and milk for an equal amount of active starter.

No caraway seeds? Celery seeds at half the amount mimic the flavor, though it won't be identical. Running out of poppy seeds? Sesame seeds work too—just know the flavor will shift slightly. The milk can be any full-fat dairy (or a plant-based substitute like oat milk if needed), but the butter must be unsalted to control the final seasoning. For the sugars, light brown sugar works in a pinch, but dark brown gives that signature caramelized crust. The foil is critical—heavy-duty aluminum foil prevents tearing during baking, and you'll need about 12x15 inches for proper sealing.

This dough is a 24-hour project, but it's worth every minute. Store the shaped loaf in a paper bag at room temperature for up to 3 days—it'll keep fresh longer than plastic. For longer storage, freeze the loaf wrapped in foil for up to 3 months. Thaw at room temperature before slicing. Pro tip: Slice with a serrated knife for clean cuts, and always slice against the grain for that perfect chewy texture. The seed swirl keeps best when stored in an airtight container—poppy seeds lose their crunch over time, so use them fresh if possible.

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

This method delivers a perfect balance of dense texture and crispy crust every time.

In a small bowl, combine the 1 cup whole milk with the 1 tablespoon honey and 0.25 cup granulated sugar. Heat this mixture in the microwave for 30 seconds until warm to the touch (about 110°F)—it should feel like bathwater. Sprinkle the 0.25 oz active dry yeast over the surface and let it sit for 5-10 minutes until foamy.

This step is crucial for proper yeast activation. You'll know it's ready when the mixture bubbles vigorously and smells slightly sweet. If it doesn't foam within 10 minutes, your yeast may be dead—start over with fresh yeast. Once activated, this mixture will create the bread's signature tangy sweetness and help develop that beautiful crust.

In the bowl of a stand mixer fitted with the dough hook, combine the 3 cups rye flour, 1 cup all-purpose flour, 1.5 teaspoons salt, and 0.5 cup dark brown sugar. Mix on low speed for 30 seconds to aerate the flours. Add the yeast mixture, 0.5 cup melted unsalted butter, and 1.5 cups water.

Mix on medium speed for 5-7 minutes until the dough pulls away from the sides of the bowl and forms a shaggy mass. The dough should be sticky but manageable—this is normal for rye bread. If it's too wet, add 1 tablespoon rye flour at a time until it comes together. The rye flour gives that authentic earthy flavor while the all-purpose flour adds structure.

Continue kneading on medium speed for another 5-7 minutes until the dough becomes smooth and elastic. You'll know it's ready when it passes the "windowpane test"—stretch a small piece between your fingers and it should thin enough to see light through without tearing.

This kneading time is shorter than traditional bread because rye flour contains less gluten. The dough will be softer than wheat dough, which is perfect for that dense, chewy texture we want. Once kneaded, transfer the dough to a lightly oiled bowl, cover with a damp towel, and let it rise in a warm place for 1-2 hours or until doubled in size. The warm environment helps the yeast work efficiently—place the bowl near your oven with the light on for consistent warmth.

While the dough rises, toast the 2 tablespoons caraway seeds and 1 tablespoon poppy seeds in a dry skillet over medium heat for 2-3 minutes until fragrant. Let them cool completely. In a small bowl, mix the toasted seeds with 1 tablespoon honey to create your swirl filling.

Once the dough has risen, turn it out onto a lightly floured surface and gently shape it into a rectangle about 12x8 inches. Roll out the dough to about ¼-inch thickness, then spread the seed mixture evenly over the surface, leaving a ½-inch border around the edges. Starting from the long side, tightly roll the dough into a log, sealing the seam.

Place the rolled loaf seam-side down in a greased 9x5-inch loaf pan. Cover with a damp towel and let it rise for another 30-45 minutes until it's about 1 inch below the top of the pan. Preheat your oven to 425°F.

Here's where the magic happens: line a baking sheet with the aluminum foil and place it upside-down over the loaf pan. This foil-sealing technique creates steam that develops the bread's signature crispy crust while keeping the interior moist. Bake for 30 minutes with the foil sealed, then remove the foil and bake for another 15-20 minutes until the bread is deep golden brown and sounds hollow when tapped on the bottom.

Remove the bread from the oven and transfer it to a wire rack to cool completely for at least 1 hour. This resting period allows the crumb to set and the flavors to develop fully. The bread should be firm enough to slice cleanly without crumbling.

Slice the loaf into ¼-inch thick pieces for that classic deli bread experience. The exterior should be crisp and caramelized, while the interior reveals a dense, moist crumb with beautiful swirls of caraway and poppy seeds. Store wrapped at room temperature for 2-3 days or freeze for up to 3 months—it actually tastes better the next day as the flavors meld together.

Pro cooking tips for perfect results

Foil-Seal Mastery

The foil-sealed crust is what transforms this bread from good to bakery-quality. Line a baking sheet with heavy-duty aluminum foil (like Reynolds) and place it upside-down over your loaf pan before baking.

This creates a steam chamber that locks in moisture while browning the crust to a deep golden caramel. I use two layers of foil for extra insurance against tearing—especially important with sticky rye dough.

Remove the foil after 30 minutes to let the crust crisp fully in the final 15-20 minutes. 🔥

Cold Fermentation Secret

For deeper flavor without extra time, try a cold fermentation after shaping. Place your loaf in the fridge (covered) for 12-16 hours before baking. The slow fermentation enhances the rye's tang and develops a more complex flavor profile. I often do this overnight—it's hands-off and worth the wait. Just

Seed Swirl Perfection

Toast your caraway and poppy seeds until fragrant—this amplifies their flavor by 30% compared to raw seeds. Mix them with 1 tbsp honey to create a sticky paste that adheres perfectly to the dough. Spread the mixture evenly, leaving that ½-inch border to prevent seeds from breaking through during baking. For extra crunch, sprinkle an additional ½ tsp seeds on top before baking. Pro tip: Use a pastry brush to gently press the seeds into the dough's surface for even distribution.

Dough Temperature Control

Your dough should be between 75-78°F when it goes into the oven. Use an instant-read thermometer to check the internal temperature of your shaped loaf before baking.

If your kitchen is cold (below 68°F), let the dough rise near your oven's pilot light or in a proofing box (like a Breville Smart Oven) to maintain consistent warmth. Cold dough bakes unevenly and can develop a pale crust.

Scoring for Success

Before baking, use a razor blade or sharp serrated knife to score the loaf in a diagonal crosshatch pattern (about ⅛-inch deep). This prevents over-expansion and creates those beautiful bakery-style seams.

For extra drama, brush the scored areas with melted butter before baking—it adds a glossy finish and intensifies the caramelization. I like to score just before the final 15 minutes of baking when the crust is fully set.

Oven Spring Hacks

For maximum oven spring, place your loaf pan on the middle rack of a preheated oven at 425°F. If your oven runs hot, reduce the temperature to 400°F and add 5 minutes to the baking time.

For even better results, place a tray of water on the lower rack during baking to boost steam circulation. This creates a lighter, airier crumb—just like your favorite deli bread. I also recommend baking on convection mode if your oven has it, for a more even crust.
