Ingredients

  • 2 tbsp butter
  • 2 tbsp minced onion
  • 1 cup almond flour
  • 2 tsp baking powder
  • ¼ tsp baking soda
  • ½ tsp onion powder
  • ½ tsp onion flakes
  • ¼ tsp sea salt
  • ¾ cup mozzarella cheese
  • 2 tbsp cream cheese
  • 1 egg
  • 1 egg white
  • 1 tsp white vinegar

Instructions

Equipment Needed

Directions

  • Heat oven to 375° and line a baking sheet with a non stick baking mat or parchment paper. Heat a skillet on medium high and add the butter. Once hot, fry the minced onion until it begins to brown, then remove from heat and set aside.
  • Combine almond flour, baking powder, baking soda, onion powder, onion flakes and sea salt in a medium sized microwave safe bowl and mix well. Toss in shredded mozzarella, then place the cream cheese on top. Microwave for 1 minute. Mix with a wooden spoon, then microwave for an additional 30 seconds.
  • Mix again, and if the mozzarella is not fully melted, microwave in 15 second intervals until it is. Fold in 1 egg and 1 egg white and once fully combined, knead in the vinegar.
  • Divide into four and form into buns. They will flatten out while baking so be sure not to form them flat. Place evenly on a baking sheet with a non stick baking mat, then brush the tops with the cooked onion/butter. Bake for 14-16 minutes, until the tops of the buns have browned.

Notes

Expert Tips

  1. Mince the onion fairly small so that they are not huge chunks of onion on top of your buns.
  2. Once the vinegar hits, the dough will instantly start to puff up a little bit. Be gentle while shaping the buns to keep the most volume possible.
  3. This recipe can easily be doubled or tripled if you are having lots of company over, or if you want to make a large to batch to freeze.
