Preheat oven to 390ºF | 200ºC and line an oven tray with parchment paper.
In a small saucepan, heat milk, sugar, lemon peel and cinnamon, without boiling. Remove from heat and set aside.
Whisk the eggs in a bowl and place them in a dip dish.
Cut the two bread baguettes into 0.5 to 0.8-inch | 1,5 to 2cm slices.
Dip each slice of bread first into the milk mixture, soaking well, and second in the egg wash and place into the oven tray, placing each slice with a bit of space between them.
Finish by brushing the rest of the egg over the slices for the perfect golden brown crust. Reserve the milk to do the same after baking.
Place the french toast in the oven until golden brown, about 10 minutes on each side.
In a deep dish, mix well the sugar with the cinnamon. Dip each warm french toast in the remaining milk and coat with the sugar cinnamon mix. They're ready to eat!
