Let your oven preheat at 350°F while preparing the dish.
Arrange the bacon slices on a baking sheet in a way that they don’t overlap. Leave in the oven for 10-15 minutes until brown and crispy. Remove once cooked. Transfer the bacon grease (bacon fats leftover in the tray) to a bowl and reserve. Let the bacon sit for a few minutes then chop them into bits.
Allow the eggs to boil in a pot filled with water. When ready, peel off the shells. Slice the eggs into thin portions and season well with salt, pepper, butter, and mayonnaise and mix in the bacon.
