Keto Quiche Lorraine

The Keto Quiche Lorraine combines a buttery keto-friendly pie crust filled with a savory mixture of eggs, heavy cream, caramelized onions, bacon, and Gruyere cheese. Aromatic thyme and a hint of nutmeg season the custard, resulting in a rich quiche with a tender, slightly firm texture and crisp crust. It offers a low-carb alternative to the classic French dish, retaining its creamy interior and smoky bacon flavor.

Ingredients

  • 1 Keto Pie Crust see notes
  • 8 lices uncured bacon
  • 4 egg whole
  • 1 cup heavy cream
  • 1 cup gruyere cheese shredded
  • ½ cup yellow onion thinly sliced
  • 2 teaspoons thyme or 1 teaspoon dried, fresh
  • ⅛ teaspoon ground nutmeg
  • ⅛ teaspoon salt
  • ⅛ teaspoon black pepper ground

Instructions

    Cup of Yum
  1. Preheat oven to 350°F
  2. Roll out the pie crust and place inside a 9” nonstick tart pan with a removable bottom. Prick the bottom of the crust with a fork and bake for 8 minutes, then remove and set aside.
  3. While the crust is baking, add the bacon to large skillet and fry until slightly crispy. Allow to cool before chopping, then set aside.
  4. Drain some of the bacon grease, leaving about 2 tablespoons in the pan. Add in the onions and sauté until they are just starting to caramelize.
  5. In a large mixing bowl, add in the eggs, heavy cream, salt, pepper, nutmeg and thyme, then mix until well combined.
  6. Add in most of the bacon, most of the cheese and all of the onions to the baked pie crust. Pour the egg mixture over the top, then sprinkle the remaining cheese and bacon on top.
  7. Bake for 25-30 minutes or until the eggs are cooked through. If the edges of the crust start to brown before the eggs are cooked, you can gently wrap them with strips of aluminum foil and continue baking. Allow to sit at room temperature for 10 minutes before cutting into slices.

Notes

  • The keto pie crust should omit sweetener and include a pinch of salt for this recipe.
  • For a crustless version, simply omit the crust and follow remaining steps.
  • If no tart pan is available, use a pie dish instead.
  • Gruyere cheese adds ideal flavor, but Swiss cheese can be used as a substitute.
  • If you prefer, parsley can replace thyme as the herb seasoning.
