Preheat oven to 450 and line a sturdy cookie sheet with parchment paper or a silicone baking mat.
Separate eggs, putting the whites in a large mixing bowl and the yolks in separate little cups.
Whip the whites at high speed until stiff peaks form, about 2-3 minutes.
Gently stir in the cheese, then divide the whites into 4 “cloud” shapes on the baking sheet. Make a little well in the center of each cloud.
Bake for 3 minutes, then slide the cookie sheet out and gently slip a yolk into each well. Cook for another 3 minutes.
Gently remove with a spatula and serve!
Notes
Eggs: We use extra large eggs for this recipe, but you can use any size you have on hand.
Cheese: Parmesan cheese is always our choice for this recipe – it adds a little gentle saltiness – but you can use any kind of shredded or crumbled cheese. Or you can leave the cheese out altogether if you want a pure egg taste!
