Ingredients

Pie Crust

  • 1 9-inch Pie Crust

Vegetables

  • 1 tablespoon Olive Oil
  • 0.5 cup Sweet Onion, diced Peeled and diced
  • 8 ounces Button Mushrooms, sliced Cleaned and sliced
  • 9 ounces Baby Spinach

Seasonings

  • 1.5 teaspoons Salt
  • 1 teaspoon Pepper
  • 0.5 teaspoon Ground Nutmeg

Egg Mixture

  • 4 large Eggs
  • 0.25 cup Milk
  • 0.5 cup Cottage Cheese
  • 1 cup Swiss Cheese, shredded

Instructions

  • Step 1: Preheat the Oven. Begin by preheating your oven to 375°F (190°C).
  • Step 2: Sauté the Vegetables. In a large skillet, heat the olive oil over medium heat. Add the diced sweet onion and sauté until translucent, about 3-4 minutes. Add the button mushrooms and cook until browned, about 5 minutes. Stir in the baby spinach and cook until wilted, about 2-3 minutes. Remove from heat and let cool slightly.
  • Step 3: Prepare the Egg Mixture. In a large mixing bowl, whisk together the eggs, milk, cottage cheese, salt, pepper, and nutmeg until smooth.
  • Step 4: Combine the Ingredients. Add the cooled vegetable mixture to the egg mixture, stirring gently. Fold in the Swiss cheese until evenly distributed.
  • Step 5: Assemble the Quiche. Place the pie crust in a 9-inch pie dish and pour the spinach and mushroom mixture into the crust.
  • Step 6: Bake the Quiche. Bake in the preheated oven for about 35-40 minutes, or until set in the center and lightly golden on top.
  • Step 7: Cool and Serve. Let the quiche cool for at least 10 minutes before slicing. Serve warm or at room temperature.

Notes

For a crispier crust, pre-bake the pie crust for 10 minutes before adding the filling. Feel free to experiment with different cheeses or add cooked bacon for a meatier version.
