Ingredients:
- 1 (9-inch) Deep-dish pie crust
- 1 tbsp Extra virgin olive oil
- 1 small yellow onion, finely diced
- 10 oz Fresh baby spinach
- 1 cup Sharp white cheddar cheese, shredded
- 1/4 cup Parmesan cheese, finely grated
- 4 large eggs
- 1 1/2 cups Whole milk
- 1/2 tsp Sea salt
- 1/4 tsp Ground black pepper
- 1/8 tsp Ground nutmeg
Instructions:
- Preheat your oven to 375°F (190°C). Note: A hot start ensures the crust begins to set before the liquid soaks in.
- Sauté the diced onion in olive oil over medium heat until translucent and soft.
- Add the fresh baby spinach to the pan in batches. Note: It looks like a lot, but it will shrink by 90 percent.
- Cook the spinach 4 minutes until wilted and dark green.
- Remove the spinach from the pan and squeeze it in a clean kitchen towel. Note: You must see at least 1/4 cup of green liquid come out.
- Whisk the 4 eggs, milk, salt, pepper, and nutmeg in a large bowl. Note: Whisk until no streaks of yolk remain for a uniform color.
- Spread the squeezed spinach and diced onions across the bottom of the pie crust.
- Layer the 1 cup of white cheddar and 1/4 cup of parmesan over the vegetables.
- Pour the egg mixture slowly over the fillings. Note: Let it seep down through the cheese layers naturally.
- Bake for 45 minutes until the edges are golden and the center has a slight jiggle.
- Allow the quiche to cool for 10 minutes before slicing to ensure the custard structure sets properly.
