Equipment

Ingredients

  • ½ tablespoon olive oil
  • ½ cup chopped onions
  • ½ cup sliced mushrooms
  • 1 clove garlic -minced
  • ¼ teaspoon kosher salt -divided
  • ⅛ teaspoon coarsely ground black pepper
  • 1 cup baby spinach
  • 2 large eggs
  • 4 tablespoons heavy cream
  • ½ cup cubed smoked gouda or Gruyere cheese (2.5 oz)
US - Metric

Instructions

  • Preheat the oven to 375°F (190°C).
  • Place a 10-inch skillet on medium-high heat. Add olive oil and swirl to coat the pan evenly.
  • Add chopped onions, mushrooms, minced garlic, ⅛ teaspoon of salt, and pepper. Cook, stirring occasionally, until onions are translucent and mushrooms are soft, about 4-5 minutes.
  • Add spinach and stir until it begins to wilt, about 1-2 minutes. Remove the pan from heat and set aside.
  • In a medium mixing bowl, whisk together eggs, cream, and remaining ⅛ teaspoon of salt.
  • Fold the spinach and mushroom mixture into the egg mixture, then stir in the cheese.
  • Pour the mixture into a lightly greased 5×5-inch baking dish. Place the baking dish on a rimmed baking sheet to catch any possible spills.
  • Bake until the quiche is puffed and golden, about 25 minutes.

Notes

  • Choose the Right Baking Dish: For best results, we strongly recommend using a 5×5-inch baking dish that holds about 1.5 cups and has an area of 25 square inches. A 4×6-inch dish with an area of 24 square inches is also a good choice.
  • Pre-cook the vegetables: This prevents excess moisture from making the quiche soggy.
  • Whisk the egg and cream thoroughly: Ensures a smooth and creamy texture.
  • Let it cool slightly before serving: This helps the flavors to meld together.
  • Don’t overbake: Overbaking can make the quiche dry.
  • Store leftovers properly: Keep any leftovers in an airtight container in the fridge for up to 3 days.
