Ingredients

• 10 large eggs
• 0.5 cups milk
• 4 cups baby spinach
• 8 oz mushrooms
• 1 medium onion
• 2 cloves garlic cloves
• 1 cup shredded cheese (cheddar or mozzarella)
• 1 tablespoon olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.25 teaspoons paprika

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until translucent.

Step 3

Stir in the minced garlic and sliced mushrooms. Cook for 5-7 minutes, stirring occasionally, until the mushrooms release their moisture and are tender.

Step 4

Add the baby spinach to the skillet and cook for 2-3 minutes until wilted. Remove the skillet from heat and let the mixture cool slightly.

Step 5

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and paprika until fully combined.

Step 6

Fold the mushroom and spinach mixture into the egg mixture. Mix well to evenly distribute the vegetables.

Step 7

Pour the mixture into the prepared baking dish. Sprinkle the shredded cheese evenly over the top.

Step 8

Place the casserole in the preheated oven and bake for 30-35 minutes, or until the center is set and the edges are golden brown.

Step 9

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

Step 10

Enjoy as-is or serve with a side of fresh fruit or crusty bread for a complete meal.
