You can create a flavorful, delicious meal with a few simple ingredients in just a few minutes. We take advantage of small quantities of leftovers in the freezer and toss them into the basic quiche mixture. We can have a quiche in the oven in less than 15 minutes and let the oven work its magic.

Basic Quiche Ingredients

Eggs: Choose the best quality, free-range eggs you can find. If you can find home-grown eggs, that is your best option.
Milk, half-and-half, or cream: If using milk, choose whole milk instead of skim or 2% milk fat. It will make the quiche’s mouth feel more luxurious.
Cheese: A variety of cheeses can be used for quiche. Some of the most popular are cheddar, Swiss, and Gouda.
Homemade or store-bought pie crust: Making pie crust is easy, but refrigerated store-bought crusts are a great time-saver if time is limited. You can also use a pastry crust if you’d like.
Salt: Add a pinch of kosher salt or sea salt to enhance the flavors.
White pepper: White pepper is better than black pepper. It is made from the same berry from the same plant, but it is peeled before drying. This creates a light-colored peppercorn that has a less bitter bite than black pepper. It is more mild and is used in lighter-colored dishes, so there are no black flakes in the dish.
Nutmeg: Grate a bit of whole nutmeg into the mixture for a great flavor.

Optional Ingredients

The list of optional ingredients is really limitless. Use whatever vegetables and proteins you have in the pantry, freezer or fridge. Popular optional ingredients include;

Bacon
Ham
Sausage
Chicken
Spinach
Broccoli
Asparagus
Onions
Zucchini
Herbs

How to Reheat in the Oven

We always make at least one extra quiche when we are making them. It only takes a few extra minutes, and we love the leftovers. They make an easy, delicious breakfast or lunch the next day.

The oven is the best method for reheating the whole quiche. It will maintain a crispy, flaky crust and the delicious taste of fresh from the oven. If the crust gets very brown when it is initially cooked, cover it with strips of foil or a pie guard.

For Whole Quiche

Preheat the oven to 325°F. Remove the quiche from the fridge and uncover it.
Line a baking sheet with parchment paper or aluminum foil.
Place the whole quiche in the pie plate on the baking sheet, uncovered.
Bake for 10-15 minutes for a whole quiche.
Let the quiche rest for about five minutes so the filling can firm up a bit before cutting and serving it.

For Quiche Slices

Preheat the oven to 325°F. Remove the quiche from the fridge and uncover it.
Line a baking sheet with parchment paper or aluminum foil.
Arrange slices on the baking sheet.
Bake for 8-10 minutes until they are hot.
Let slices rest a couple of minutes.
Serve.

How to Reheat in a Toaster Oven

The toaster oven will maintain the crispy crust of the quiche, and it is faster to preheat than a conventional oven.

Place slices of quiche directly on the toaster oven rack.
Toast them at 350°F for five minutes until hot and lightly browned.
Let them rest a couple of minutes before serving.

Reheating Quiche in the Air Fryer

The air fryer is our favorite way to reheat quiche. It is really quick, and the crust returns to its former crispiness. The top gets a bit browned.

Remove the quiche from the refrigerator.
Brush the crust lightly with milk, melted butter or oil. This will create an extra crispy crust.
Preheat the air fryer to 300°F.
Arrange the slices in the basket so they aren’t touching. Air fry for 4-8 minutes until heated through.
Let them rest for a couple of minutes. Serve.

How to Reheat Quiche in the Microwave

The microwave is the fastest way to reheat quiche. It does an adequate job but the crust will get soggy. Only reheat slices in the microwave, not whole quiches.

Place a slice of quiche on a microwave-safe plate.
Cover with a piece of paper towel.
Microwave on high for 1½ minutes. Check the temperature of the quiche. If it isn’t quite hot enough, microwave it for another 30 seconds.
Let it rest for one minute before eating.
Don’t reheat any longer than two minutes, or the texture of the crust will be either very soggy or hard.
