Preheat oven to 400 degrees F (200 degrees C). Lightly coat a muffin tin with oil.

Line 8 muffin cups with 1 slice of bacon each. Crack an egg into each mold, season with salt and pepper and give each cup a sprinkle of cheese (you can also add the beneath the egg).

Bake in the preheated oven until egg whites are completely set, about 15 minutes. Top with black pepper.

If you wish to cook these in an air fryer, find silicon molds that will fit the bottom of your air fryer. They come in single molds or in molds of 4. Place all the bacon and eggs in a mold then gently lift them into the air fryer basket. Air fry for 330 for 10 minutes. You don’t want the temperature too high or else the eggs will burn on top.
