America's Test Kitchen Rye Bread Recipe: Crusty Crumb and Tangy Depth

America's Test Kitchen rye bread recipe delivers the perfect balance of crusty exterior and tangy, open crumb that professional bakers covet. After years of perfecting this classic, I've developed a method that ensures consistent results—no more dense loaves or overly sour flavors.

The secret lies in precise fermentation times and a carefully balanced mix of rye flour and malted barley.

This recipe transforms simple ingredients into a golden-brown crust with a satisfying crackle and a moist, slightly chewy interior. The tang comes from malted barley flour and a touch of molasses, but it's never overpowering—just enough to enhance the bread's depth.

With two hours of hands-off fermentation, you'll achieve optimal flavor development without sacrificing texture.

What sets this apart is the foolproof technique for achieving that signature rye bread aroma and texture. The dough is mixed once (no kneading required), left to ferment at room temperature, then shaped and proofed before baking.

This method ensures a crispy crust that shatters when sliced and a crumb that's just open enough to hold onto that rich, malty flavor.

Once baked, you'll have a loaf that's perfect for sandwiches, toast, or simply enjoying with butter. The recipe includes troubleshooting tips for common issues like overly dense bread or uneven baking. Let's get started on this restaurant-quality rye bread at home.

Ingredients for america's test kitchen rye bread

Precision-milled flours and malted barley create that signature rye flavor without bitterness.

The light rye flour is non-negotiable for achieving that signature open crumb. Bob's Red Mill has the optimal malt content, but any quality light rye will work—just avoid dark rye which can overpower the flavor. Malted barley flour from the bulk section at Whole Foods delivers the most authentic tang. If you're using store-bought, check the label for at least 50% malt content. The all-purpose flour acts as a structural balance—King Arthur unbleached creates the perfect chew without gumminess. For the yeast, Saf-Instant is my go-to as it activates directly in cold water, eliminating the need for proofing. Store all flours in airtight containers to prevent oxidation, which dulls flavor and reduces shelf life.

No malted barley flour? Substitute with an additional 0.25 cup light rye flour plus 1 tsp malt syrup—it's not identical, but closer than skipping it entirely. For the molasses, unsulphured is critical—sulphured varieties add unwanted bitterness. Running short on time? Replace 1 tbsp molasses with 1 tsp honey, though the flavor will be slightly less complex. The butter should be cold and cubed—microwave for 10 seconds if needed to soften slightly, but never melt it completely. For the egg wash, use pasteurized eggs if concerned about raw egg consumption. The cornmeal? Stone-ground is ideal for texture, but regular works fine. All ingredients should be measured by weight for precision, though cups work for this recipe's forgiving ratios.

This dough ferments best at 70-75°F—use an oven with the light on if your kitchen runs cold. The shaped loaf keeps 3 days at room temperature wrapped in a clean kitchen towel, or 1 week in the fridge. For longer storage, slice and freeze individual portions—3 months maximum. To revive, toast directly from frozen for 2-3 minutes longer than fresh. The crust develops best when sliced immediately after baking, but can be reheated at 350°F for 5 minutes if needed. For sandwiches, slice while still warm to prevent gumminess.

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

This method delivers a perfectly balanced loaf with a crisp crust and moist interior.

In a large mixing bowl, combine the 3 cups light rye flour, 1 cup all-purpose flour, 0.5 cup malted barley flour, 0.25 cup granulated sugar, 0.5 tsp instant-release yeast, and 1.5 tsp diamond crystal kosher salt. Mix just until these dry ingredients are evenly distributed. Create a well in the center and add the 0.25 cup cold, cubed unsalted butter and 2 tbsp molasses. Using a rubber spatula, work the butter and molasses into the flour mixture until you achieve a coarse, sandy texture with small butter pieces visible.

Gradually add the 1.5 cups cold water while mixing with the spatula, stirring until a shaggy dough forms. The dough will be extremely sticky at this stage—this is normal for rye bread. Cover the bowl with a damp kitchen towel and let it rest at room temperature for 12 hours. This long fermentation develops the bread's characteristic tang and depth of flavor. The dough should nearly double in volume and develop a slightly sour aroma.

After the 12-hour rest, the dough will be very soft and sticky. Using a dough scraper, transfer the dough to a lightly floured work surface. Sprinkle the surface with additional light rye flour as needed to prevent sticking. Gently fold the dough over itself 3-4 times, using the scraper to help manipulate it without overworking. This folding technique strengthens the gluten structure while maintaining the bread's dense texture.

Shape the dough into a smooth, slightly tapered rectangle about 8x12 inches. Fold the long sides inward toward the center, then fold the top and bottom edges inward to create a compact package. Transfer the shaped dough to a baking sheet dusted with 0.25 cup cornmeal, seam-side up. Cover with the damp towel and let it rise at room temperature for an additional 2 hours. The dough should expand noticeably and develop a slightly domed appearance.

Preheat your oven to 375°F with a Dutch oven inside for 30 minutes. Remove the Dutch oven from the oven and carefully transfer the dough to it. Brush the top of the dough generously with the 1 whole egg wash (beaten with 1 tsp water). Using a sharp serrated knife, score the top of the dough with a deep crosshatch pattern, cutting about 1/4 inch deep. This scoring prevents excessive expansion during baking and creates an attractive crust.

Place the Dutch oven back in the oven and bake for 25 minutes. Remove the lid and continue baking for an additional 20-25 minutes until the bread is deeply golden brown and internal temperature reaches 205°F. The crust should sound hollow when tapped on the bottom, and the bread should pull away slightly from the sides of the Dutch oven. Let the bread cool on a wire rack for at least 1 hour before slicing to allow the interior to set properly.

For best results, store the bread wrapped in a clean kitchen towel inside an airtight container at room temperature for up to 3 days. The bread will continue to develop flavor as it cools. To reheat, wrap the bread in foil and warm in a 350°F oven for 10-15 minutes until heated through. The interior should remain moist and the crust should regain its crisp texture.

This rye bread's distinctive characteristics come from the combination of malted barley flour and molasses, which create both the signature tang and rich depth of flavor. The dense crumb and crisp crust make it ideal for sandwiches or enjoyed with butter and jam. Each slice should reveal a slightly sticky, moist interior with a well-developed crust that contrasts beautifully with the tender crumb.

Essential equipment for perfect results

Dutch Oven

Your Dutch oven is the single most important tool for achieving that signature rye bread crust. I recommend a 5-quart enameled cast iron Dutch oven like the Le Creuset Signature—it retains heat exceptionally well and provides even baking.

The heavy lid creates steam during the initial baking phase, which is crucial for developing that crispy, shatterable crust. If you don't have a Dutch oven, a heavy baking stone with a metal bowl placed on top can mimic the effect, though results won't be identical. 🔥

Digital Thermometer

Precision is key with rye bread, and a digital instant-read thermometer like the Thermoworks Thermapen ONE ensures you nail the perfect internal temperature. The dough should reach 205°F at the center before pulling it from the oven.

This tool also helps monitor your oven's accuracy—preheat your oven with the Dutch oven inside, then check the temperature before baking. I've found many home ovens run 25°F hotter or colder than their set temperature, which can drastically affect your bread's texture.

Dough Scraper

A stainless steel dough scraper is indispensable when working with sticky rye dough. I use a West Bend dough scraper—the flexible edge helps lift and fold the dough without tearing it. The flat side also makes quick work of cleaning up flour on your work surface.

For shaping, the scraper helps create clean edges and prevents the dough from sticking to your hands. A 12-inch scraper gives you enough reach to handle the dough's final dimensions without overworking it.

Kitchen Scale

While this recipe works well with cup measurements, a digital kitchen scale like the OXO Good Grips takes your rye bread to the next level. Flour density varies by brand and even day-to-day, so weighing your ingredients ensures consistency.

For this recipe, focus on weighing the light rye flour and malted barley flour—these are the most critical for flavor and texture. A 1% accuracy scale is ideal, but even a basic $15 model will improve your results significantly over cup measurements alone.

Cornmeal Dusting

While cornmeal isn't essential, it creates a non-stick surface for your shaped dough and adds a subtle flavor. Use stone-ground cornmeal for the best texture—brands like Bob's Red Mill work perfectly. Dust your baking sheet generously before transferring the shaped dough.

This prevents sticking and helps create a crispy bottom crust. For extra insurance, chill the shaped dough in the fridge for 15-20 minutes before transferring to ensure clean handling.

Proofing Box

A proofing box or simple DIY version (a plastic container with a light bulb inside) maintains the ideal 75-80°F temperature for fermentation. Without one, your kitchen may be too cold, leading to weak gluten development.

If you don't have a proofing box, place your dough near the oven's pilot light or use the warm setting on your dishwasher (with the rack removed). The goal is consistent warmth—fluctuations can cause uneven rising and poor texture.

I've seen doughs that took 4 hours to proof properly in a cold kitchen versus 1.5 hours in a warm one.
