Ingredients:

  • 1 tablespoon olive oil (15 ml)
  • 1 small onion, finely chopped (about 1 cup)
  • 4 ounces fresh spinach, roughly chopped (115g)
  • 1/4 teaspoon salt (1.5g)
  • 1/4 teaspoon black pepper (1.5g)
  • 4 large eggs (US XL size)
  • 1 cup whole milk (240 ml)
  • 1/2 cup heavy cream (120 ml)
  • 1/2 cup grated Gruyere cheese (50g), or Swiss cheese
  • Pinch of grated nutmeg

Instructions:

  1. Preheat oven to 375°F (190°C).
  2. Heat olive oil in a large skillet over medium heat. Add onion and sauté until softened, about 5 minutes. Add spinach, salt, and pepper, and cook until spinach is wilted, about 2 minutes. Remove from heat and set aside.
  3. In a large mixing bowl, whisk together eggs, milk, cream, nutmeg, salt, and pepper until well combined.
  4. Stir in the cooked spinach mixture and Gruyere cheese into the egg mixture.
  5. Pour the mixture into the prepared pie dish.
  6. Bake for 35-40 minutes, or until the quiche is set and lightly golden brown on top. A knife inserted into the center should come out clean.
  7. Let the quiche cool for at least 10 minutes before slicing and serving.
