Ingredients
  

Buttermilk Biscuits

  • 1 1/4 cups all purpose flour
  • 1 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 2 1/2 Tbsp cold butter (salted stick butter works best)
  • 1/2 cup buttermilk (or milk)
  • 1/4 cup thick sourdough discard
  • Melted butter for brushing the tops (about 1 Tbsp)

Filling

  • 1/2 lb. uncured bacon
  • 10 small mild cheddar cheese slices (or 5 big)
  • 2 eggs (organic, free range is what I use)
  • ground black pepper to taste
  • salt to taste

Instructions
 

Make the Biscuits

  • Preheat oven to 425 degrees and line a baking sheet pan with parchment paper
  • Combine flour, baking soda, baking powder, and salt in a mixing bowl.
  • Use a cheese grater to shred butter or cut cubes of butter into the flour mixture with a fork until pea-sized.
  • Add in buttermilk (or milk) and sourdough starter. Mix until combined. Add 2-4 Tbsp extra buttermilk if needed. Use hands to help combine
  • Turn dough out on the counter and use your hands to pat or a rolling pin to roll dough until it’s 3/4 inch thick
  • Cut biscuits out with a biscuit cutter (I use a 3 inch one) or mason jar with a straight up-and down motion. Do not turn the cutter.
  • Combine any scraps and repeat. You'll want to get 5 biscuits out of the dough.
  • Place biscuits on the prepared sheet pan 2 inches apart. Brush tops with melted butter.
  • Bake biscuits at 425 degrees for 15 minutes until light golden brown and puffy.
  • Remove from oven and brush tops again with melted butter.

Make the Bacon

  • Line a baking sheet pan with parchment paper.
  • Place each slice 1/2 inch apart from one another on the sheet pan and sprinkle 1/4 tsp pepper on bacon.
  • Place in the oven with the biscuits and bake at 425 degrees for 12-15 minutes.
  • Pull out of the oven and place on a wire rack over a pan or paper towel to let the grease drip off. Set aside to cool.

Make the Eggs

  • Heat a medium sized skillet over medium heat with 1-2 tsp of avocado oil or bacon grease.
  • While the biscuits and bacon are cooking, whisk together the egg, 1/4 tsp salt, and 1/8 tsp pepper in a small bowl.
  • Then pour egg mixture into the warmed pan and cook for 2-3 minutes on medium heat.
  • Then flip and cook an additional 1 minute. This should look like a crepe. Slice egg into 5 pieces and set aside.

Assemble biscuits

  • Once everything is cooked, slice each biscuit in half.
  • Add a slice of bacon broke in half, a piece of cooked egg folded to fit the biscuit and 2 slices of cheese between the biscuit halves.
  • Optional - Warm assembled biscuits in the oven at 425 for 2 minutes or until cheese melts. Enjoy!
