Leek Onion Brussels Sprouts Quiche Pie Recipe

This irresistible Leek, Onion & Brussels Sprouts Quiche Pie is a delicious experiment turned family favorite! I had leftover pastry and fridge-clearing ingredients, and the result is a surprisingly flavorful and satisfying quiche. Tender leeks and onions perfectly complement the earthy Brussels sprouts in a creamy, flaky crust. Feel free to add a little broccoli or cauliflower, but the original combination is truly exceptional. The amount of sprouts is flexible – use 1-2 handfuls (approximately 1-2 cups) depending on size. Get ready for a quick and easy weeknight meal that tastes like a gourmet creation!

How to Make Leek Onion Brussels Sprouts Quiche Pie

  1. Preheat oven to 375°F (190°C).
  2. Prepare the pastry crust: Roll out your pre-made or homemade pastry and fit it into a 9-inch pie dish. Prick the bottom with a fork.
  3. Sauté the leeks and onions: In a large skillet, sauté 1 cup sliced leeks and 1/2 cup chopped onions in 1 tablespoon of olive oil until softened, about 5-7 minutes.
  4. Add Brussels sprouts: Add 1-2 cups trimmed and halved Brussels sprouts to the skillet and cook for another 5-7 minutes, until slightly tender-crisp.
  5. Whisk the egg mixture: In a bowl, whisk together 4 large eggs, 1 cup heavy cream, 1/2 cup grated cheddar cheese (or your preferred cheese), 1/4 teaspoon salt, and 1/4 teaspoon black pepper.
  6. Assemble the quiche: Pour the egg mixture over the sautéed vegetables in the pie crust. Gently stir to combine.
  7. Bake: Bake for 45-55 minutes, or until the quiche is set and golden brown. Let cool slightly before slicing and serving.
