Ingredients

• 2 tablespoons olive oil
• 1 tablespoon unsalted butter (optional)
• 1 medium yellow onion, diced
• 2 cloves garlic cloves, minced
• 8 ounces cremini mushrooms, sliced
• 4 cups fresh spinach, roughly chopped
• 4 large eggs
• 1 cup half-and-half cream
• 1 cup shredded Swiss cheese
• 1 half cup crumbled feta cheese
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 0.125 teaspoon ground nutmeg (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or tart pan with nonstick spray or a thin layer of butter.

Step 2

Heat the olive oil and unsalted butter (if using) in a large skillet over medium heat.

Step 3

Add the diced onion and sauté for 3-4 minutes until softened and translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant.

Step 4

Add the sliced mushrooms to the skillet and sauté for 5-7 minutes until they release their moisture and begin to brown.

Step 5

Stir in the fresh spinach and cook for 2-3 minutes, or until wilted. Remove the skillet from heat and let the mixture cool slightly.

Step 6

In a large mixing bowl, whisk together the eggs, half-and-half, shredded Swiss cheese, crumbled feta cheese, salt, black pepper, and nutmeg, if using.

Step 7

Add the sautéed mushroom and spinach mixture to the egg mixture, stirring to combine evenly.

Step 8

Pour the mixture into the prepared pie dish or tart pan, spreading it out evenly.

Step 9

Bake the tart in the preheated oven for 25-30 minutes, or until the center is set and the top is golden brown.

Step 10

Remove the tart from the oven and let it cool for 5-10 minutes before slicing and serving.

Step 11

Enjoy as a standalone dish or pair with a simple green salad for a complete meal.
