Ingredients
  • 1 9- inch pie crust
  • 1 tbsp olive oil
  • 2 cups aged cheddar grated
  • 1 tbsp thyme leaves
  • 1/2 cup sour cream
  • 3 large onions halved and sliced
  • 4 eggs
Instructions
  1. Preheat oven to 350. Line pie crust with paper, and "blind bake" for 10 mins, then remove paper and beans and cook a further 15 mins, until lightly golden. Allow to cool.
  2. Meanwhile, heat oil in a large pan and add onions. Sprinkle with salt and pepper. Cook over medium-low heat for about 30 mins, until a deep golden color.
  3. Spread cooled onions over pie crust. Sprinkle cheese over, then thyme leaves.
  4. Whisk eggs and sour cream together, and pour over the filling. Bake for 30-35 minutes, until the center is set and top is golden. Serve warm, or at room temperature.
  5. Enjoy!
