Equipment

Ingredients

  • 1 pound frozen hash browns thawed
  • 1 ½ teaspoons sea salt divided
  • 4 tablespoons ghee melted, divided
  • 1 cup mushrooms sliced
  • 1 leek sliced
  • 1 cup raw cashews
  • ½ cup almond milk
  • 1 tablespoons lemon juice
  • 2 tablespoons nutritional yeast
  • 1 tablespoon dijon mustard
  • 6 large eggs whisked

Instructions

  • Soak the cashews in cold water for at least 6 hours. Alternatively, you can boil the cashews for 10 minutes. Drain.
  • Pre-heat the air fryer to 400ºF.
  • Place hashbrowns on a large kitchen towel, and squeeze out as much water as possible. In the 8-inch pie pan, mix hash browns, melted ghee, and ½ teaspoon of salt. Press hash browns up the sides of the pie pan. Air fry for 15 minutes or until golden brown and crispy.
  • While the crust is cooking sauté mushroom and leeks in 2 tablespoons of ghee.  Cook on medium heat making sure not to burn the leeks.  It should take about 10 minutes before the leeks are nice and tender.  Set aside.
  • In a blender, combine cashews, almond milk, lemon juice, nutritional yeast, 1 teaspoon of salt, and Dijon mustard. Blend for 1 minute until smooth and creamy. Add in eggs and blend slowly for 30 seconds to incorporate.
  • Turn down the air fryer to 325ºF. Spoon the mushroom-leek mixture on top of the hash brown crust.  Pour the egg custard on top and bake for 25 minutes or until the custard is set.

Notes

  • Cool the quiche down to room temperature before slicing.
  • Depending on your air fryer model, the cooking times can vary. If your quiche comes out runny, try adding 3-5 minutes more time. 
  • To reheat your quiche, place it back in the air fryer at 300ºF for 3-4 minutes.
  • Use a pie or quiche pan that will fit in your air fryer basket. An 8-inch pan fits perfectly in my Gourmia Air Fryer.
