Slice the gluten-free bread and set aside. In a large bowl, whisk together eggs, milk, pumpkin puree, cinnamon, nutmeg, salt, and maple syrup until the mixture is smooth and fragrant.
Dip each bread slice into the batter, ensuring it’s fully soaked but not falling apart. Let it sit for a few seconds to absorb the flavors.
Heat a non-stick skillet or griddle over medium heat and add a little butter or oil. When hot, carefully place the soaked bread slices onto the skillet, ensuring they are not overcrowded.
Cook the slices for about 3-4 minutes on one side, watching for the batter to set and turn golden brown. Flip carefully and cook for another 3-4 minutes until both sides are crisp and golden, with a fragrant cinnamon-sugar smell filling the air.
Remove the cooked French toast and keep warm. Repeat with the remaining slices, adding more butter or oil as needed.
Serve the pumpkin French toast warm, drizzled with additional maple syrup or honey if desired, and enjoy the tender, caramelized edges and fragrant spices.
