2 egg whites
8 whole eggs
1 cup cheddar cheese, grated
salt, to taste
3-4 slices bacon
ground pepper, to taste
2 apples, Fuji or Gala
1 Tbsp butter
Put the rack in the upper third of the oven. Preheat oven to 450F.
Crack the eggs, one at a time, over a small bowl. After checking for stray shells, pour each egg into a medium bowl. To separate the egg whites, crack the egg over an egg separator or someone’s clean hands. Carefully let the egg white slip through the fingers into the bowl, with the yolk remaining. Discard the yolk or save for another recipe. Using a whisk, beat the eggs until the yolks and whites are thoroughly combined.
Grate the cheese. Younger children can help you use a rotary cheese grater (which protects their skin). Older children can use a box grater. Add half of the grated cheese to the egg mixture and stir to combine. Add a pinch of salt and pepper, to your liking.
Cook the strips of bacon. You can fry them in a skillet (watch out! They can splatter.) Or, you can bake them in the oven on a cooling rack over a rimmed baking sheet. We like this method because we don’t have to turn the bacon over and the kids stay safe.
Once the bacon cools, crumble the strips with clean hands. Use a vegetable peeler to peel the apple. If you have an apple corer, you may use it. Or, simply cut up the apple, leaving the core behind. Slice the apple pieces very thinly. As you are cutting, be sure to put the flat side of the apple pieces down, so the chunks don’t wobble on your cutting board.
In a medium cast-iron or nonstick ovenproof skillet, heat the butter over medium heat. Add egg mixture to the skillet. Sprinkle the bacon crumbles evenly over the eggs. Gently arrange the apples on top of the egg mixture, in a circular pattern. Sprinkle with remaining cheese.
Move the skillet from the stovetop to the upper rack of your oven. Bake until frittata is firm in the center and cheese is browned, about 20 minutes. Use a flexible spatula to loosen the frittata from the pan. Carefully slide it onto a cutting board. Allow to cool for a few minutes before slicing into wedges.
