In a wide, shallow dish, whisk together the eggs, milk, vanilla extract, cinnamon, oragne, and nutmeg until well combined.
Place a slice of bread into the egg mixture, allowing it to soak for about 30 seconds on each side. This step is key in achieving that soft, custardy interior. Repeat with the remaining slices.
Heat a non-stick skillet or griddle over medium heat and melt the butter.
Add the soaked slices of bread to the skillet, cooking for about 3-4 minutes on each side, or until golden brown and crisp. Be patient during this step to ensure a perfectly crispy exterior.
Serve your French Toast warm with a generous drizzle of maple syrup, a dusting of powdered sugar, and if you like, a scattering of fresh berries.
