Ingredients For Vegetarian Quiche Recipe
Pie crust: The base of the quiche, providing a flaky and buttery texture.
Milk: Adds creaminess to the quiche filling.
Eggs: The main binding ingredient that sets the quiche.
Cheddar cheese: Adds a rich, savory flavor to the quiche.
Spinach: Provides a fresh, slightly earthy taste and vibrant color.
Mushrooms: Adds a meaty texture and umami flavor.
Salt: Enhances the overall flavor of the quiche.
Ground black pepper: Adds a hint of spice and depth to the dish.
Technique Tip for Making Quiche
When preparing the pie crust, make sure to blind bake it for about 10 minutes before adding the filling. This helps to prevent a soggy bottom. To do this, line the crust with parchment paper and fill it with pie weights or dried beans. After blind baking, remove the weights and parchment, then proceed with adding the egg mixture.

How to Store or Freeze Your Quiche
Allow the quiche to cool completely at room temperature before storing. This helps prevent condensation, which can make the crust soggy.
Wrap the quiche tightly with plastic wrap or aluminum foil. Ensure that it is well-sealed to maintain freshness and prevent any odors from the refrigerator from seeping in.
For short-term storage, place the wrapped quiche in the refrigerator. It will stay fresh for up to 3-4 days. Reheat individual slices in the microwave or oven before serving.
For long-term storage, consider freezing the quiche. First, wrap it in plastic wrap, then place it in a resealable freezer bag or wrap it again with aluminum foil. This double-layer protection helps prevent freezer burn.
Label the quiche with the date it was made before placing it in the freezer. This will help you keep track of its freshness. The quiche can be frozen for up to 2-3 months.
When ready to enjoy, thaw the quiche in the refrigerator overnight. This gradual thawing process helps maintain the texture and flavor.
Reheat the quiche in a preheated oven at 350°F (175°C) for about 20-25 minutes or until heated through. Cover it with foil to prevent the crust from over-browning.
For a quicker option, you can reheat individual slices in the microwave. Place a slice on a microwave-safe plate and heat on medium power for 1-2 minutes, or until warmed through.
How to Reheat Leftovers
Oven Reheating: Preheat your oven to 350°F (175°C). Place the leftover quiche on a baking sheet and cover it loosely with aluminum foil to prevent the crust from over-browning. Heat for about 15-20 minutes or until the quiche is warmed through. This method helps maintain the crust's crispiness and the filling's texture.
Microwave Reheating: Place a slice of quiche on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. This method is quick but may result in a softer crust.
Stovetop Reheating: Heat a non-stick skillet over medium-low heat. Place the quiche slice in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method can help keep the crust slightly crispy.
Air Fryer Reheating: Preheat your air fryer to 300°F (150°C). Place the quiche slice in the air fryer basket and heat for 5-7 minutes. This method can help maintain a crispy crust while ensuring the filling is warmed through.
Toaster Oven Reheating: Preheat your toaster oven to 350°F (175°C). Place the quiche slice on a toaster oven tray and cover loosely with aluminum foil. Heat for about 10-15 minutes or until warmed through. This method is convenient and helps maintain the quiche's texture.
