Ingredients

Scale

Vegetables and Aromatics

2 tbsp mild oil (vegetable or canola)
2 cups chopped onion
2 garlic cloves, minced
10 oz fresh spinach

Seasonings

1 tsp kosher salt, divided
1/4 tsp crushed red pepper flakes

Dairy and Eggs

6 large eggs
1/4 cup heavy cream
1 1/2 cups shredded mozzarella cheese

Instructions

Preheat and Prepare: Preheat oven to 375°F (190°C) and lightly grease a 9-inch pie dish or baking pan to prevent sticking.
Sauté Onions: Heat the oil in a skillet over medium heat. Add the chopped onions and sauté for about 8 minutes until they are soft and translucent, which brings out their sweetness.
Add Garlic: Stir in the minced garlic and cook for 1–2 minutes until fragrant, ensuring it does not burn.
Cook Spinach: Add the fresh spinach gradually in batches, stirring as it wilts down. Once all spinach is incorporated and wilted, season with ½ teaspoon kosher salt and crushed red pepper flakes. Remove the mixture from heat and allow it to cool slightly.
Mix Eggs and Dairy: In a separate large bowl, whisk together the 6 large eggs, heavy cream, and the remaining ½ teaspoon of kosher salt until thoroughly combined.
Combine Ingredients: Stir in the shredded mozzarella cheese, then gently fold in the cooled spinach mixture to maintain the mixture’s light texture.
Bake: Pour the combined mixture into the prepared pie dish and spread it out evenly. Bake in the preheated oven for 20–25 minutes until the quiche is set and lightly golden on top. A knife inserted in the center should come out clean.
Rest and Serve: Remove the quiche from the oven and let it rest for 10 minutes before slicing. This allows it to firm up for easier serving.

Notes

You can substitute mozzarella cheese with another mild cheese like Monterey Jack or a blend of cheddar for a sharper flavor.
For a dairy-free version, replace heavy cream and cheese with suitable substitutes, but expect a different texture and flavor.
If preferred, add herbs like thyme or parsley for additional freshness.
Ensure the spinach is well-drained to avoid excess moisture making the quiche watery.
Use a non-stick or well-greased pie dish to make removal easier.
