Toast the slices of bread while preparing the rest, keeping a close eye on them.

Separate the egg whites and yolks, keep the yolks in their shells and mix the egg whites together, then beat the egg whites until stiff.

Add the Parmesan to the egg whites and whisk again, this time at low speed.

Butter ramekins close to the size of the bread slices and place the egg whites in them, forming a small well in the middle.

Bake for 4 minutes, add the yolk to the well, then bake again for 1 minute.

Carefully remove the eggs from the ramekins and place them on the slices of bread.
