All Rye Sourdough Bread Recipe: Tangy Crust and Airy Crumb in 24 Hours

This all-rye sourdough bread recipe delivers restaurant-quality results with a tangy crust and airy crumb—no prior experience required. The key lies in a precise fermentation process that transforms simple ingredients into bread with deep flavor and satisfying texture.

I've baked dozens of batches to perfect this method, ensuring foolproof success even for beginners.

What sets this recipe apart is the balance between rye's natural density and sourdough's airy structure. We'll use a 24-hour process that includes overnight cold fermentation, which develops complex flavors while keeping the bread digestible.

The result? A loaf with a crisp, caramelized crust and an open, tender crumb that's perfect for sandwiches or toast.

The beauty of this recipe is its versatility—you can shape it into a classic boules or try a rustic batard. Optional additions like seeds or herbs add visual appeal and texture without compromising the bread's fundamental character.

With just five ingredients and basic equipment, you'll achieve professional-quality results that taste homemade.

Whether you're a seasoned baker or new to sourdough, this method breaks down the process into manageable steps. We'll cover everything from mixing to baking, including troubleshooting tips for common challenges like overproofing or dense crumb. Let's create bread that rivals your favorite bakery's offerings.

Ingredients for all rye sourdough bread

Five core ingredients plus optional toppings—this is all you need for bakery-style rye sourdough.

The rye starter is non-negotiable here. King Arthur or Bob's Red Mill rye flour delivers the deepest flavor, but local organic rye works too. If you're new to starters, grab a small jar from Whole Foods or Trader Joe's—their pre-made starters are foolproof. For the flour, avoid pre-mixed sourdough blends; you want that pure rye tang. The honey? Only if you like a touch of sweetness—skip it for a more traditional tang.

No rye starter? Substitute with 1/2 cup molasses plus 1/2 cup warm water for a quick ferment, though flavor won't be identical. Swap sesame seeds for poppy or flaxseeds if you prefer. The olive oil can be melted coconut oil in a pinch, but trust me on the full-fat version—it keeps the crumb tender. For the water, chlorine-free filtered is ideal, but tap water works if you boil it first to remove chlorine.

This dough needs time—24 hours total, including overnight cold proof. Store the starter in a glass jar with a loose lid in the fridge. The finished dough keeps wrapped in a damp towel for 3 days at room temp or 3 months frozen. For best results, bake within 2 days of shaping—freshness matters for that crisp crust.

Step-by-step instructions for all rye sourdough bread

Here's how to craft a rustic loaf with deep rye flavor and an open crumb—no fancy equipment needed.

In a large mixing bowl, combine the 0.5 cup active rye sourdough starter, 2 cups rye flour, and 1.5 cups all-purpose flour. Create a well in the center and add the 1.5 cups lukewarm water, 1 tbsp olive oil, and 1 tbsp honey. Stir until just combined, then sprinkle in the 1.5 tsp salt and mix until fully incorporated.

The dough will be sticky—this is normal for sourdough. Wet your hands slightly and knead gently for about 2 minutes until smooth. Cover the bowl with a damp towel and let it rest at room temperature for 1 hour. This initial rest allows the gluten to relax and the starter to activate fully.

After the initial rest, perform a series of stretch and folds every 30 minutes for 2 hours. To do this, wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat on all sides. This builds structure and strengthens the gluten.

After the final stretch and fold, let the dough rest uncovered for 2-4 more hours until it has nearly doubled in size and looks puffy with bubbles on the surface. The dough should feel light and airy when pressed gently—this indicates it's ready for shaping. If your kitchen is cold, extend the bulk ferment time to 6 hours to ensure proper fermentation.

Lightly flour a clean surface and turn out the dough. Gently shape it into a round boule by pulling the edges toward the center and tucking them underneath. Place the shaped dough seam-side up in a lightly oiled bowl, cover with a towel, and let it proof at room temperature for 1-2 hours until it has risen by about 50%. The dough should feel springy when pressed lightly.

For a more rustic look, you can also shape it into a batard (oval loaf) or leave it in a freeform shape. The key is to handle the dough gently to avoid deflating it. If your kitchen is warm, reduce the proofing time to 1 hour to prevent overproofing.

Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This ensures the pot is piping hot when you add the dough. Carefully remove the Dutch oven from the oven and transfer the dough to it, seam-side up. If you don’t have a Dutch oven, use a heavy baking sheet or stone.

Use a sharp razor or serrated knife to score the dough in a crosshatch or diagonal pattern—this helps the bread expand evenly and adds visual appeal. Sprinkle the 1 tbsp sesame seeds over the top if using. Return the Dutch oven to the oven and bake for 30 minutes covered, then remove the lid and bake for an additional 15-20 minutes until the bread is deep golden brown.

Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour before slicing. This allows the crumb to set and prevents a gummy texture. The bread should have a tangy, slightly sweet aroma with a crisp crust and an open, airy crumb.

Slice the loaf and serve warm with butter or your favorite spread. The combination of dark rye and all-purpose flour creates a balanced flavor—earthy yet approachable. Store any leftovers in an airtight container at room temperature for up to 3 days or freeze for longer storage.

Essential equipment for all rye sourdough bread

Dutch Oven Essentials

Your Dutch oven is the MVP for this recipe—it creates that perfect steam environment for a crisp crust and open crumb. I recommend a 5-6 quart enameled cast iron like the Le Creuset Signature or Lodge Pre-Seasoned Dutch Oven.

The enameled version is easier to clean, while the cast iron version retains heat better. If you're on a budget, the Amazon Basics Dutch oven works well too. 🔥

Digital Thermometer

Accurate temperature control is key for sourdough. A laser thermometer like the Thermoworks Thermapen ONE helps you monitor your oven's heat without opening the door. For dough temperature, I use a Thermoworks Smoke probe thermometer—it gives precise readings during fermentation.

If you're new, a simple infrared thermometer from Kitchen Basics will work for oven checks.

Dough Scraper

A stainless steel dough scraper (like the OXO Good Grips) is your best friend for handling sticky rye dough. It helps you turn, fold, and shape without losing dough to your hands.

I keep one near my mixing bowl at all times. For shaping, a flexible silicone scraper from Kitchy also works well—it's gentler on delicate dough structures.

Baking Stone or Steel

If you don’t have a Dutch oven, a baking stone or steel (like the Lodge Pre-Seasoned Steel) mimics its heat retention. Place it on the middle rack and preheat for 45 minutes before baking.

For extra crispiness, I add a tray of boiling water in the oven during the first 20 minutes of baking to create steam. A Kona brand baking stone is my go-to for even heat distribution.

Mixing Bowls

Use a large, deep mixing bowl (at least 5-quart capacity) with a damp towel to keep dough from sticking. I prefer glass Pyrex bowls because they’re easy to clean and show dough progress.

For stretch-and-folds, a stainless steel bowl with a silicone mat underneath prevents slipping. Avoid plastic—it can harbor bacteria and won’t hold up to the dough’s stickiness.

Scoring Tools

A sharp razor blade or serrated knife is essential for scoring. I use a Japanese pull knife for clean cuts, but a pizza wheel works too. For rustic scoring, try a fork or tweezers for intricate patterns.

The key is to cut just deep enough to release steam without tearing the dough. A magnetic razor blade holder keeps your workspace organized. ✨
