Dry out the bread
If your bread is not stale yet, lay it out on a baking sheet overnight to dry, or bake it for 10-20 minutes in a 300°F oven until stiff and dry. Using stale or dried bread will help it soak up the custard, while avoiding soggy French toast.
Whisk the custard
Whisk together the JUST Egg, sugar, vanilla, cinnamon and milk in a wide shallow dish.
Soak the bread
Soak the bread slices in the custard mixture for 15-30 minutes, flipping halfway through.
Fry the toast
Bring a non-stick skillet to medium-low heat and brush with a light coating of coconut oil or butter. Use a fork or tongs to pick up each slice of bread from the soaking dish, letting any excess custard mixture drip off back into the dish. Cook each slice for about 2 minutes on each side, until browned. Serve immediately, with your favorite toppings.
