Ingredients For Vegetarian Quiche Recipe
Pie crust: A base for the quiche, providing a flaky and buttery texture.
Milk: Adds creaminess to the quiche filling.
Eggs: Helps to bind the ingredients together and gives structure to the quiche.
Shredded cheddar cheese: Adds a rich, cheesy flavor to the quiche.
Spinach: Provides a nutritious and vibrant green element to the dish.
Onion: Adds a savory depth of flavor to the quiche.
Salt: Enhances the overall taste of the quiche.
Black pepper: Adds a hint of spice and balances the flavors.
Technique Tip for Perfect Quiche
To ensure your quiche has a perfectly flaky crust, blind bake the pie crust before adding the filling. Line the crust with parchment paper and fill it with pie weights or dried beans. Bake at 375°F (190°C) for about 10-12 minutes until the edges start to turn golden. Remove the weights and parchment, then proceed with adding your egg mixture and other ingredients. This step prevents a soggy bottom and gives you a crisp, delicious base for your quiche.

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 it is well-sealed to maintain freshness and prevent it from absorbing any odors from the refrigerator.
For short-term storage, place the wrapped quiche in the refrigerator. It will stay fresh for up to 3-4 days.
For long-term storage, consider freezing the quiche. First, wrap it in plastic wrap, then place it in a freezer-safe bag or airtight container. Label it with the date to keep track of its freshness.
When ready to enjoy a frozen quiche, transfer it to the refrigerator to thaw overnight. This gradual thawing helps maintain the texture and flavor.
To reheat, preheat your oven to 350°F (175°C). Place the quiche on a baking sheet and cover it loosely with aluminum foil to prevent the crust from over-browning. Heat for about 20-25 minutes, or until warmed through.
If you prefer to reheat individual slices, you can use a microwave. Place a slice on a microwave-safe plate and cover it with a microwave-safe cover or another plate. Heat on medium power for 1-2 minutes, checking frequently to avoid overcooking.
For a crispier crust, consider reheating individual slices in a toaster oven. Set the toaster oven to 350°F (175°C) and heat for about 10-15 minutes.
Always check the internal temperature of the quiche before serving. It should reach at least 165°F (74°C) to ensure it is heated through properly.

How to Reheat Leftovers
Oven Method: 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 becoming too brown. 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 Method: 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 slightly softer crust.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the quiche on a piece of aluminum foil or a small baking tray. Heat for about 10-15 minutes, or until the quiche is thoroughly warmed. This method is great for reheating smaller portions while keeping the crust crispy.
Stovetop Method: Heat a non-stick skillet over medium-low heat. Place a slice of quiche in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through. This method helps maintain the crust's texture while ensuring the filling is evenly warmed.
Air Fryer Method: Preheat your air fryer to 320°F (160°C). Place the quiche in the air fryer basket and heat for about 5-7 minutes. This method is quick and helps keep the crust crispy.
