⭐ Soy Milk (unsweetened, plain) (Best Dairy-Free Option)

1:1 (replace whole milk volume for volume)

Quick tip: Plant-based alternative with similar protein content; may impart a slight beany flavor.

Soy milk contains proteins and fats that help mimic the structure and creaminess of whole milk in quiche custard. Its protein content supports coagulation during baking, essential for custard setting.

Use unsweetened and unflavored soy milk to avoid altering the quiche's flavor. The texture may be slightly less creamy, and the custard may be a bit softer.

The final product will be less rich and may have a subtle beany taste, but it is a viable dairy-free option for those needing it.

Oat Milk (unsweetened, plain)

1:1 (replace whole milk volume for volume)

Quick tip: Mild flavor and creamy texture; lower protein may yield a softer custard.

Oat milk is naturally creamy and has a mild flavor, making it a decent dairy-free substitute in quiche. However, it has lower protein content compared to whole milk, which can affect the custard's firmness.

Choose unsweetened, plain oat milk to avoid adding sweetness or flavors that compete with the quiche filling. Expect a slightly softer custard and possibly longer baking times.

The quiche will be less firm and slightly less rich, but oat milk is a good option for those avoiding dairy and nuts.
