Description

Baked to golden perfection, it’s a satisfying vegetarian dish that can be served warm or cold for a versatile meal.


Ingredients

Scale

Crust

  • 1 9-inch pie crust (store-bought or homemade)

Vegetables

  • 1 tablespoon olive oil
  • 1/2 head cauliflower (cut into small florets)
  • 2 cups fresh spinach (roughly chopped)
  • 1/2 cup yellow onion (diced)

Custard Mixture

  • 3 large eggs
  • 1 cup whole milk
  • 1/2 cup heavy cream
  • 1 cup shredded Swiss or Gruyère cheese
  • 1/4 teaspoon ground nutmeg
  • Salt and pepper to taste


Instructions

  1. Preheat Oven and Prepare Crust: Preheat the oven to 375°F (190°C). If using a store-bought pie crust, place it in a 9-inch pie dish and pre-bake it according to the package instructions to ensure a crisp base.
  2. Sauté Vegetables: Heat the olive oil in a skillet over medium heat. Add the cauliflower florets and cook until they are lightly browned and tender, about 8–10 minutes. Add the diced onion and cook for an additional 3 minutes. Stir in the chopped spinach and cook just until wilted. Remove the skillet from heat and allow the vegetables to cool slightly.
  3. Prepare the Custard: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, shredded cheese, ground nutmeg, salt, and pepper until smooth and well combined.
  4. Combine Ingredients: Fold the sautéed vegetables into the custard mixture. Stir gently to evenly distribute.
  5. Assemble Quiche: Pour the vegetable and custard filling into the pre-baked pie crust. Smooth the top with a spatula to ensure an even surface.
  6. Bake the Quiche: Place the quiche in the preheated oven and bake for 35–40 minutes, until the custard is set in the center and the top is lightly golden brown.
  7. Cool and Serve: Remove the quiche from the oven and let it cool for 10 minutes before slicing and serving. Enjoy warm, at room temperature, or cold as desired.

Notes

  • You can substitute whole milk with a dairy-free alternative and use a gluten-free pie crust to accommodate dietary restrictions.
  • For extra flavor, roast the cauliflower before sautéing.
  • This quiche is delicious served cold or at room temperature, making it a great make-ahead meal.
