Marble rye bread on a cooling rack.

Marble Rye Bread

No reuben sandwich is complete without Marble Rye Bread. Swirls of dark and light dough make this classic, caraway-flecked Marble Rye Bread look like you bought it at a bakery.

For the light dough:

  • 1 teaspoon active dry yeast
  • 3/4 cup plus 2 tablespoons water warm (100-110 degrees Fahrenheit)
  • 1 3/4 cups (8 ounces) bread flour
  • 4 ounces medium rye flour
  • 1 1/4 teaspoons kosher salt
  • 1 teaspoon caraway seeds
  • 1 1/2 tablespoons vegetable oil
  • 1 tablespoon molasses

For the dark dough:

  • 1 teaspoon active dry yeast
  • 3/4 cup plus 2 tablespoons water warm (100-110 degrees Fahrenheit)
  • 1 3/4 cups (8 ounces) bread flour
  • 4 ounces medium rye flour
  • 1 1/4 teaspoons kosher salt
  • 1 teaspoon caraway seeds
  • 3 tablespoons cocoa powder
  • 1 1/2 tablespoon vegetable oil
  • 1 tablespoon molasses

For baking:

  • vegetable oil for oiling bowls
  • Nonstick cooking spray for shaping
  • 1 large egg for egg wash


To make the light dough:

  • Activate the yeast: In a small bowl, pour in the yeast. Gently pour the warm water over the yeast and allow it bloom for 5 minutes.
  • Make the dough: In a standing mixer fit with the paddle attachment on low speed, mix together the bread flour, rye flour, salt, yeast, water, caraway seeds, vegetable oil, and molasses until combined, about 2 minutes. Switch from the paddle attachment to the dough hook, and knead on medium-low speed until the dough is smooth and tacky, about 10 minutes.
  • Form the dough: Place dough on a clean surface and press into an 8-inch circle. Using your hands, stretch and fold the dough up and over itself from all sides into the center, crimping it where the folded ends meet, to form it into a tight round ball that is smooth on the bottom.
  • First rise: Lightly oil a bowl that is twice the size of the dough, and set the dough into the bowl, seam side down. Tightly cover with plastic wrap. Set aside in a warm area until doubled in size, about 1 1/2 hours.

To make the dark dough:

  • Immediately after making the light dough, repeat the process to make the dark dough. Add more water a tablespoon at a time if needed to make the dough feel the same consistency as the first one. Stretch and fold the dough into a ball and let it rise in another lightly oiled bowl.

To shape the loaf:

  • Divide the doughs: When both doughs have doubled in size, divide each dough in 2 equal pieces. (You will have 4 pieces total)
  • Shape dough into squares: Lightly oil a flat work surface. Using your hand or rolling pin, gently shape each piece into a 6-inch square about 1/4 inch thick. Stack the dough squares alternating light and dark dough. Firmly press down so all four pieces stick to each other.
  • Roll the stack: Starting with the side closest to you, tightly roll the stack up into the loaf, pinching the seam closed with your fingertips to seal. Set the loaf seam side down and gently roll and stretch dough until it is the same length as a 9-inch by 5-inch loaf pan.
  • Second rise: Place loaf seam side down in the loaf pan, coat the top with cooking spray. Cover pan tightly with plastic wrap and set aside in a warm place until doubled in size. (see note)

To bake the loaf:

  • Preheat oven: Position a rack in the center of the oven and preheat to 350 degrees.
  • Egg wash: In a small bowl whisk together the egg with 1 tablespoon of water. Lightly brush the top of the loaf with the egg wash. Discard any leftover egg wash. Place loaf in the oven and bake for 20 minutes.
  • Rotate loaf: Rotate the loaf pan and continue until golden brown, about 20 minutes more. Transfer the loaf in the pan onto a wire rack to cool. Once the pan is cool enough to handle, remove the bread from pan and allow cool completely before slicing.


  1. Active dry yeast: Red Star, Fleischmann's, and most other yeast brands sell packets that contain 1/4 ounce or 2 1/4 teaspoons of yeast per packet. Below, learn how to test yeast to ensure if it's active.
  2. Bread flour: Bread flour is higher in protein (usually 11 to 14%) than all-purpose flour, and the extra protein helps gluten develop. Look for unbleached white bread flour.
  3. Rye flour: Rye flour is usually sold in smaller packages at the store because it tends to have a shorter shelf life than all-purpose flour.
  4. Caraway seeds: Caraway seeds are pungent little seeds that are essential in most classic rye bread recipes. Feel free to add more if you prefer very seedy bread.
  5. Kosher salt: Opt for this since it's flakier and fluffier than table salt.
  6. Cocoa powder: Dutch-process or natural cocoa both work fine.
  7. Kneading: The consistency of the light and dark doughs need to be the same so they can stick together when rolled and baked.
  8. Yield: One batch of the recipe makes 1 loaf of bread.
  9. Storage: Store the bread at room temperature loosely covered with a plastic bag, or pre-slice the entire loaf, place it in a zip-top bag, and store it in the refrigerator.
  10. Freezing: Freeze bread while still fresh. Allow to cool completely, then seal the loaf up in a zip-top plastic bag. To thaw, let the bread come to room temperature, about 3 hours. To serve warm, wrap the loaf in parchment paper and foil and heat in a 400-degree oven for 3 to 4 minutes.
  11. Testing yeast for freshness: Dissolve 1/2 teaspoon sugar in 1/2 cup warm water. Add one packet (or 2 teaspoons) yeast, stir, and wait 10 minutes. If the yeast mixture is bubbly and domed, your yeast is active and ready to go. (You can use the same yeast you tested–just reduce the liquid in your recipe by 1/2 cup.)
  12. How to proof dough: Yeast bread needs a warm, draft-free space to rise, a process called proofing. Here's how I make a perfect warm area: Turn the oven on to the lowest temperature it will go, usually 200 degrees. Once it reaches 110 degrees, turn the oven off. Place the dough in the oven and close the door. Opening the oven door will lower the heat a bit, and that’s okay (you’re aiming for 75 to 85 degrees). Repeat as needed for second proofing.
  13. Check for doneness: The internal temperature of the loaf should be between 195 to 200 degrees.
  14. Cool before slicing: Allow the bread to cool 1 to 2 hours before slicing.
