Crustless Quiche Lorraine, a low-carb version of the classic dish, is made with a rich egg custard, bacon, onions and gruyere cheese. You will never miss the crust.
Heat the oil in a large skillet over medium heat. When the oil is hot, saute the onion until soft (about three minutes). Remove the onions. Season with a pinch of salt and pepper. Remove the skillet from the heat.
Spray a 9-inch pie pan with cooking spray. Layer ⅓ of the bacon and onions in the pie pan and top with half of the cheese. Layer another ⅓ of remaining bacon and onions in the pie pan and add with the remaining cheese. Top with the remaining bacon and onions
Gently beat the eggs with a wire whisk until combined. Add the cream, nutmeg, salt and pepper and stir to combine. Pour the egg mixture over the onions, bacon and cheese.
Bake for 35 - 40 minutes or until the quiche is set and develops a light golden brown on top. Let the quiche sit for 10 to 15 minutes, then slice and serve.
