β Silken Tofu and Soy Milk (Best Dairy-Free Option)
1/2 cup silken tofu + 1/2 cup unsweetened soy milk per 1 cup heavy creamSilken tofu blended with soy milk provides a creamy, protein-rich base that mimics the texture of heavy cream. The tofuβs smoothness helps achieve a custard-like consistency, while soy milk thins the mixture to a pourable state.
Blend thoroughly until completely smooth to avoid graininess. This substitute works well in vegan or dairy-free quiches but may require seasoning adjustments to compensate for the neutral flavor.
The resulting quiche is less rich and slightly denser, with a mild bean-like undertone that is generally subtle but noticeable compared to traditional heavy cream.
