Getting the perfect texture
The key to the perfect light and airy quiche texture is getting the eggs-to-dairy ratio just right. It’s the difference between a stiff, dry quiche versus one that is perfectly delicious and fluffy!
Thankfully, the ratio is easy to remember. You simply need 2 eggs for every 1 cup of dairy. That’s it!
This recipe uses 6 eggs, so we need 3 cups of dairy. We split this up between 1 1/2 cups of milk and 1 1/2 cups of cheese.
That’s all there is to it! Just be sure to keep this ratio in mind if you start experimenting with your own ingredients, especially if you decide to add more cheese. You’ll have to adjust the amount of milk used to ensure the ratio is still balanced.
Get creative with your ingredients!
It’s so much fun to play around with different ingredients for this dish. Honestly, it’s hard to go wrong! A good rule of thumb: if you’ve seen it in an omelet, it will probably be delicious in a quiche.
The bacon and onion in this recipe are the ingredients for a classic quiche Lorraine. Another popular variation is the spinach and feta quiche, which is equally delicious.
But there are literally thousands of other options out there!
Whether you’re clearing out your refrigerator or just want to try something new, here are some ideas for more fillings to try:
- Bell peppers
- Kale or spinach (these work well with some feta cheese too!)
- Cooked broccoli or cauliflower
Cheeses and meats:
- Any light cheese
- Sliced sausages
- Cold meats
- Freshly diced garlic cloves
- Pickled asparagus and artichoke
The ingredient combinations are endless, so go ahead and get creative!
Did you know that crustless quiche can be made ahead?
In fact, this dish freezes really well for when you need to whip up something impressive in a flash!
To freeze a quiche, cook it for 3/4 of the total time (so roughly 33 – 37 minutes), remove from the oven, and allow it to cool to room temperature. Make sure it’s fully cooled so you don’t end up with condensation, which will give you a soggy quiche.
Once fully cooled, wrap the quiche in plastic or place it in an airtight container and freeze. You can keep it in the tart pan or remove and set on a plate.
Before serving, remove from the freezer and allow it to sit at room temperature for a few hours. Then simply bake at 350F (180°C) for 15 minutes and serve!
If you have leftovers of fully-cooked quiche, store in an airtight container in the refrigerator for up to 5 days or in the freezer for several months.
