Sourdough Onion Rye

This bread machine rye gets its tangy backbone from sourdough starter and its savory depth from diced onions folded right into the dough.

Unlike many bread machine ryes that rely on white flour with a token scoop of rye, this one builds its base entirely from whole wheat and rye flours. Vital wheat gluten compensates for the lower gluten content in those heavier flours, giving the loaf enough structure to rise properly in the machine without collapsing.

Honey or molasses adds a malty sweetness that balances the sour tang from the starter. The optional anise or caraway extract is worth including if you love a classic deli-style rye. Even a small amount perfumes the whole loaf.

Three sizes are included (small, medium, large), so you can match the recipe to your machine’s capacity. Scale the vital wheat gluten up if your loaf comes out dense. The recipe allows for doubling the gluten flour amount, which is smart insurance with whole grain doughs.

Pro Tips

• Make sure your sourdough starter is active and bubbly before adding it. A sluggish starter won’t contribute enough lift or tang.
• Add ingredients in the order your bread machine manual recommends. Most machines want liquids first, but some are the opposite.
• Vital wheat gluten is not optional here. Without it, the heavy rye and whole wheat flours will produce a dense, brick-like loaf.
• If your loaf browns too quickly on top, tent it with foil for the last 15 minutes of baking (if your machine allows opening).

Variations

• Beer rye: Replace the water with a dark lager for deeper malt flavor.
• Seeded crust: Brush the top with egg wash and press caraway or poppy seeds into the surface before the final bake cycle.
