Basic ideas: Don’t let the bread soak too lengthy within the egg custard combination — doing so can break down the bread. Retailer-bought, pre-sliced brioche is particularly delicate.
Vegan: Omit the eggs, half-and-half, and butter. To the custard, substitute 2 cups oat milk and 4 tablespoons dairy-free butter, improve the cornstarch to six tablespoons and add 4 tablespoons floor sesame seeds or floor flax seeds for richness and taste. Go for sturdier slices like sourdough or peasant bread and cook dinner as directed.
Storage: Refrigerate leftover French toast in an hermetic container inside 2 hours of cooking and retailer for as much as 1 day. Reheat within the air fryer at 400°F for 8 minutes, turning midway.
