Description

A wholesome crustless quiche loaded with sautéed mushrooms, spinach, and creamy cheese—perfect for a protein-rich breakfast, brunch, or light lunch.


Ingredients

Units Scale
  • 1 tbsp olive oil
  • 1/2 small onion, diced
  • 1 cup sliced mushrooms
  • 2 cups fresh spinach, chopped
  • 5 large eggs
  • 1/2 cup milk (dairy or unsweetened plant-based)
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup crumbled feta or goat cheese
  • 1/2 tsp garlic powder
  • Salt and pepper to taste

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9-inch pie dish.
  2. Heat olive oil in a skillet over medium heat. Add onions and mushrooms, and sauté until soft and lightly browned, about 5–6 minutes.
  3. Add spinach and cook until wilted, about 1 minute. Remove from heat and let cool slightly.
  4. In a mixing bowl, whisk together eggs, milk, garlic powder, salt, and pepper.
  5. Stir in mozzarella and sautéed vegetables.
  6. Pour mixture into prepared pie dish and sprinkle with crumbled feta.
  7. Bake for 35–40 minutes, or until the center is set and the top is golden.
  8. Let rest 5 minutes before slicing and serving.

Notes

  • Great for meal prep—store leftovers in the fridge for up to 4 days.
  • Use a nonstick pie dish or line with parchment for easier cleanup.
  • Customize with other vegetables or cheese blends as desired.
