Sweet Potato Crust
- Preheat oven to 425 degrees and spray a 9 inch cast iron skillet or other oven proof skillet with cooking oil.
- Place the shredded sweet potatoes in a bowl of water and toss around to release some of the starch.
- Drain and place the sweet potatoes in a clean towel and squeeze out any excess liquid.
- Place the sweet potatoes back in the bowl, add in the egg white, flour, salt and pepper and toss until coated.
- Dump the sweet potato mixture into the prepared skillet and press into an even layer along the bottom and up the sides.
- Bake for 20-25 minutes or until golden.
- Remove from the oven and add in the quiche filling.
- Lower the oven temperature to 375 degrees.
- Heat a 9 inch cast iron skillet or other ovenproof skillet over medium heat.
- Use kitchen scissors or a knife to cut the bacon into bite sized pieces and add them to the heated skillet.
- Cook the bacon until crisp then drain it on a plate lined with paper towels.
- Remove the excess grease from the skillet, but don’t wipe clean.
- Add the green onions and spinach to the skillet and sauté until the spinach is wilted.
- Remove the spinach and onions from the skillet and onto the plate with the bacon.
- Once the spinach has cooled enough to handle, squeeze out any excess liquid.
- In a large bowl whisk together all of the filling ingredients reserving 1/4 cup of the shredded cheeses.
- Pour the filling into the baked sweet potato crust and top with the remaining 1/4 cup of cheese.
- Place the quiche in the oven and bake for 35-40 minutes or until the filling is set and the top is golden.
- Remove from the oven and let it rest for 5-10 minutes before serving.
