Detailed Guide: Each Egg Substitute in Quiche
Silken Tofu
Silken tofu works well because its high water content and protein create a custard-like consistency when blended, mimicking the coagulation properties of eggs during baking. The proteins in tofu firm up upon heating, helping to bind the quiche filling effectively.
For best results, blend the tofu until completely smooth to avoid graininess and combine it thoroughly with seasonings and other ingredients. Avoid using firm tofu as it lacks the necessary moisture and smoothness.
The final quiche will have a slightly denser texture but remain creamy and sliceable, closely resembling traditional egg-based quiche without imparting a strong flavor.
Chickpea Flour Batter
Chickpea flour contains proteins and starches that coagulate when heated, providing structure and binding similar to eggs. When mixed with water, it forms a batter that sets into a firm custard-like texture.
Mix chickpea flour and water thoroughly to avoid lumps and season well to mask the legume flavor. Pre-cooking the batter slightly can improve texture and reduce raw flour taste.
The quiche will be slightly denser and have a subtle earthy flavor, but it holds together well and maintains a good sliceable texture.
Aquafaba
Aquafaba, the liquid from cooked chickpeas, mimics egg whites' foaming and binding properties due to its protein and carbohydrate content. It helps bind ingredients but lacks the fat and yolk components that contribute to richness and firmness.
Whip aquafaba slightly before folding into the quiche mixture to improve aeration and binding. It works best combined with a thickener like flour or starch to improve custard firmness.
The resulting quiche will be lighter and less creamy, with a slightly more fragile structure compared to egg-based quiche.
Cashew Cream
Cashew cream provides fat and creaminess similar to egg yolks, while cornstarch acts as a binder and thickener to simulate egg coagulation. This combination helps create a rich, creamy quiche filling.
Use unsweetened cashew cream and combine with cornstarch well to avoid lumps. Be mindful of the increased fat content and adjust seasoning accordingly.
The quiche will be richer and creamier but have a nuttier flavor and softer texture than traditional egg quiche.
Arrowroot Starch Slurry
Arrowroot starch gelatinizes when heated, helping to bind ingredients and provide some firmness. However, it lacks protein, so it cannot replicate the custard texture fully.
Mix arrowroot starch with cold water to form a slurry before adding to the quiche mixture. Avoid overheating to prevent breakdown of the gel.
The final quiche will be firmer but less creamy and more gelatinous, with a texture noticeably different from egg-based custard.

What NOT to Use as a Egg Substitute in Quiche
Applesauce adds unwanted sweetness and moisture, which disrupts the savory balance and texture of quiche, resulting in a soggy and overly sweet filling.
While chia gel can bind ingredients, it imparts a gelatinous texture and visible seeds that negatively affect the smooth custard consistency expected in quiche.
Many commercial egg replacers are designed for baking and lack the ability to create the firm, creamy structure needed in quiche, leading to a crumbly or overly dense filling.
