This Crustless Spinach Quiche recipe uses feta cheese and is reminiscent of the flavors in Spanakopita. This easy quiche doesn't have a crust and is naturally low-carb, gluten-free, diabetic, Atkins and keto-friendly.
Preheat oven to 325º Fahrenheit. Butter or grease a 9 inch pie dish.
Heat a medium skillet over medium low heat. Add butter. When butter melts, stir in the onions. Cook onions until soft and translucent and just beginning to brown on the edges. Stir in garlic. Cook gently,while stirring until garlic is fragrant--about one minute. Remove pan from the heat and set aside.
In a medium mixing bowl, whisk together the eggs, heavy cream, oregano, sea salt, and red pepper flakes. Set aside.
Tranfer the onion and garlic mixture to the pie dish. Spread evenly.
Sprinkle the feta cheese over the onion and garlic mixture.
Evenly distribute the spinach over the feta cheese, breaking up any clumps.
Give the egg mixture one more stir, then pour it over the ingredients in the pie dish.
Bake in the preheated oven for 50-55 minutes, or until the the quiche is set and starting to brown on top.
