The slices of bread are completely infused with the egg mixture. Prepare it at night and fry it up in the morning.
I've been making French toast this way for a long time. I made them with soy milk this time.
For those who want to make a low-calorie version:Use soy milk. Instead of sugar, I use 1 teaspoon of an erythritol-based low-calorie sweetener, and leave out the butter and oil. The key is to thoroughly infuse the bread with the egg mixture. Soaking overnight gives a perfect result. If you're in a hurry, let the bread soak for at least 20 minutes.
