Ingredients

  • Olive oil cooking spray
  • 1 tablespoon olive oil
  • 2 medium onions, thinly sliced (12oz)
  • 1 teaspoon kosher salt, divided
  • 6 large eggs, lightly beaten
  • 1/2 cup plain Greek yogurt
  • 1/4 teaspoon ground pepper
  • 1/8 teaspoon ground nutmeg
  • 1/4 cup coconut flour
  • 1/2 cup shredded sharp cheddar

Instructions

  • Preheat oven to 350 degrees F. Spray a 9-inch pie plate with nonstick cooking spray.
  • Heat the olive oil in a large, deep skillet over medium-high heat, about 2 minutes. Add the onions and 1/2 teaspoon kosher salt and cook, stirring often, 8 minutes, until lightly browned. Remove from heat and allow to slightly cool.
  • Meanwhile, in a large bowl, whisk together the eggs, yogurt, 1/2 more teaspoon kosher salt, black pepper, nutmeg and coconut flour. Using a spatula, mix in the cheese and the caramelized onions.
  • Transfer the mixture to the prepared pie plate. Bake 40-45 minutes, until puffed and set and a toothpick inserted in the center of the quiche comes out clean.
  • Remove from oven. Cool 10 minutes in the baking dish on a cooling rack, then carefully run a knife around the edges to loosen. Invert onto a cutting board, then back to the cooling rack to finish cooling, about 10 more minutes.
  • Carefully transfer the quiche back to the cutting board. Use a sharp knife to cut into 6 slices, and serve.
