Inspired by Eggslut's infamous breakfast sandwiches, this recipe calls for a special egg cooking method that I only recently learned. To be honest, if you would have asked me what a marbleized egg was few months ago, I would have had looked at you with pure confusion.

Little did I know that this cooking method, that I once referred to as the lazy girls' scramble, was actually a thing. Thanks to Vice's awesomefood channel, Munchies, I now know that the marbleized egg was actually popularized by Eggslut, a super awesome – you guessed it – egg sandwich restaurant in LA. 


  • 1 bagel (everything)
  • 2 slices muenster cheese
  • 3 slices bacon
  • 2 tbsp onions
  • 2 eggs

Steps to Make It

  1. Begin by frying two slices of bacon over medium heat until crispy. Remove bacon from the pan but leave the renderings and grease.

  2. Add onions to the bacon grease and cook for a few minutes on medium-low until they become caramelized.

  3. Remove the onions and add the 2 eggs in the remaining grease. With a plastic spatula or wooden spoon, run the tip through the egg yolks and the whites so that both colors become intertwined with each other.

  4. Meanwhile, put your bagel in the toaster. Let the eggs cook for a few minutes until the whites become opaque and the yolks are cooked through.

  5. Once the first side is cooked half way through, gently flip the egg, turn the heat to medium low, add the cheese, and cover – letting the egg cook through while the cheese melts. Now that all the components are prepared, it's time to build the sandwich.

  6. Once the bagel is toasted, add the cooked egg with the melted cheese and onions. I recommend chopping the bacon before you add it to the sandwich so that each bite is consistent. Add the other piece of the bagel and serve.
