Best Substitutes for Egg Wash

Milk contains lactose (milk sugar) and proteins that brown when heated above 300F through the Maillard reaction. The fat content (3.25% in whole milk) provides some shine, though not as much as egg yolk. Brush on a thin, even layer 5-10 minutes before baking. Works best on breads, dinner rolls, and simple pastries where you want browning without intense shine.

Heavy cream has 35% fat content, which creates better browning and more shine than regular milk. The higher fat content also helps create a slight protective barrier. Apply with a pastry brush in thin coats. The richness makes it perfect for croissants, Danish pastry, and other buttery baked goods where you want a golden finish.

Aquafaba contains proteins that mimic egg whites when heated. Mix the aquafaba with water to thin it for easy brushing. It creates a shinier finish than milk but won't brown as deeply. The proteins help create a slight protective seal. Works best when you need shine without dairy. Brush on just before baking for best results.

Oat milk has natural starches and some protein that help with browning. The creamy texture brushes on smoothly and provides moderate shine. Use 2-3 tablespoons per application. The mild, slightly sweet flavor won't interfere with most baked goods. Creates a lighter golden color than dairy milk but still gives an appealing finish.

Soy milk has more protein than most plant milks (about 3-4 grams per cup), which helps with browning. The protein content creates a golden finish similar to dairy milk. Use unsweetened versions to avoid over-browning from added sugars. Apply in thin layers for even coverage. The neutral flavor works in both sweet and savory applications.

Combining melted butter with milk gives you the browning power of milk proteins plus extra richness from butter fat. The butter adds flavor and helps create a golden, slightly crispy surface. Mix while butter is still warm but not hot to prevent curdling the milk. Brush on immediately before baking for best adhesion.

Canned coconut milk has 17-24% fat content, which creates good browning and shine. Use the thick cream from the top of the can, not the watery part. The high fat content helps create a golden surface with moderate shine. Works especially well in tropical-flavored baked goods or where a hint of coconut complements the recipe.

Whisking oil and water creates a temporary emulsion that brushes on evenly. Use light olive oil to avoid strong flavor. The oil provides browning and shine while the water helps it spread smoothly. The emulsion breaks down quickly, so mix just before using and brush immediately. Creates a golden, slightly crispy surface.

Water won't brown or add shine, but it helps steam the surface for a slightly softer crust. Use when you want to prevent over-browning or when dietary restrictions eliminate other options. Brush on just before baking. The steam created helps seeds or salt stick to the surface. Works as a basic adhesive for toppings without changing flavor or color.
