Detailed Guide: Dairy-Free Whole Milk Substitutes in Sourdough Bread

⭐ Oat Milk (unsweetened, full fat) (Best Dairy-Free Option)

1 cup oat milk per 1 cup whole milk

Quick tip: Adds mild sweetness and similar viscosity but lower protein and fat than whole milk.

Oat milk has a creamy texture and mild flavor that can approximate whole milk's moisture contribution. However, its lower protein and fat content means it provides less gluten support and crumb tenderness.

Choose unsweetened, full-fat oat milk to avoid adding unwanted sugars. You may need to slightly increase hydration or add a small amount of fat (e.g., oil) to compensate.

The bread will be softer than water-based substitutes but less rich and tender than with dairy milk, with a subtle oat flavor.

Soy Milk (unsweetened, full fat)

1 cup soy milk per 1 cup whole milk

Quick tip: Higher protein content helps gluten development, but flavor is distinct and may alter sourdough taste.

Soy milk contains more protein than most plant milks, which supports gluten structure and dough elasticity. Its fat content is lower than whole milk but sufficient to maintain moisture.

Use unsweetened, full-fat soy milk to avoid adding sugar and to maintain fat levels. Be aware of the beany flavor which can subtly change the bread's flavor profile.

The final bread will have a tender crumb and good rise, though with a slight flavor deviation from traditional sourdough.
