Mug Bread


  • 4 slices bacon
  • 2 large eggs
  • 2 slices cheddar cheese


Mug Bread

  • Place butter in a large mug and melt in the microwave on high for 30 seconds.
  • Add the remaining ingredients and whisk together using a fork. Microwave on high for 90 seconds to 2 minutes until fully cooked through.
  • Allow to cool and then remove to a cutting board. Slice in half and set aside as you cook the remaining ingredients.


  • Cook bacon in a large skillet over medium-high heat and then transfer to a paper towel lined plate to drain.
  • Turn the heat down to medium and crack two eggs into the skillet. Cook until desired done-ness (we recommend over medium).
  • Assemble sandwich: Place one slice of cheese on one half of bread, top with two slices of bacon, one egg, the remaining bacon and egg and finally the second slice of cheese.
  • Serve immediately.
  • Note: You can use the biscuit recipe provided above and in the recipe video or try our Keto Air Fryer Biscuits as seen in the photos.
    Feel free to make two sandwiches out of this recipe! Matt likes to make "big boy" sandwiches and double the ingredients called for in one sandwich!
