Y’all. I love quiche! It is one of my favorite breakfast dishes. Caramelized Onion & Spinach Quiche is a delicious breakfast option filled with veggies, cheese, and all the breakfast goodness you can want!
The First Step in Making a Quiche
Personally, I believe you need a homemade pie crust.
Now if that isn’t your thing or you don’t have time – no worries, you can use a store bought one. BBBUUUUTTTTTT I think the homemade version tastes 10x better and is really not that hard to make.
The first step in making a quiche with homemade crust is to blind bake the crust. This is for 1 major reason.
- To bake the bottom of the crust so you don’t have a soggy bottom (where are my Greatest British Baking Show fans at?! Paul and Mary Berry would be very disappointed in a soggy bottom). If you put the egg mixture right into an unbaked pie crust and place in the oven, the bottom will never get fully baked because of all the moisture from the eggs.
How Do I Blind Bake A Pie Crust?
Once your pie crust is in a pie plate, place a sheet of wax or parchment paper over top. You want this to be bigger than the actual pie.
Pour pie weights (*affiliate link) or I just use a bag of dried pinto beans (just from your local grocery store) and keep them for this specific use only, on top of the paper. Spread the weight out evenly amongst the pie crust, making sure that you get all the way to the edges. Place in the oven and bake for 30 minutes.
While the crust is baking, you can start caramelizing your onions (which takes 30 minutes as well) and prepping your egg base.
How To Caramelize Onions
There is one major key to this.
Low and slow.
You cannot rush this process. It takes time but it is oh so worth it.
In a large skillet add 1 tablespoon of butter and turn on medium low. Slice a whole onion very thinly. I just use a mandolin for this – I think it is easier (I use this one I got off Amazon and it does a great job) or you can use a knife as well. Just make sure your knife is sharp and you cut even and thin slices.
Place the onion in the skillet with the butter and stir with a wooden spoon to coat the onions. You will cook over medium low heat for about 30 minutes. During this time the onions will begin to sweat, become translucent, and evenly start to brown and caramlize making the most delicious, sweet, and nutty flavor. Your house will smell amazing!
Continue to stir on and off during the 30 minutes. If you think your onion has soaked up all the butter and is beginning to stick to the pan, just add some more.
How to Prep The Quiche Base
While the pie crust and onions are cooking, go ahead and prep your egg base for the quiche.
- Beat your eggs with the milk and spices.
- Shred your swiss cheese.
- Add the cheese to the eggs mixture.
Once your onions are almost finished (with 5-10 minutes remaining) add in 3 big handfuls of spinach to the skillet. It doesn’t take long to whilt down.
Once the spinach is wilted and the onions caramalized, take off the heat and cool for 5 minutes.
Add to the eggs miture and stir until everything is evenly combined.
When the pie crust is finished, remove from the oven and carefully remove the pie weights or beans. This is where having the paper bigger than the pie shell comes in handy. You can just pick up the edges, form a “funnel” and pour the weights or beans right back into their storage container (mason jars are PERFECT for this!).
Pour the egg mixture into the blind baked pie crust and place into the oven to bake for 45 minutes.
You will know when the quiche is finished when the top is slightly golden brown and the middle is set. At 45 minutes take an oven mit and gently shake the quiche. If the middle still “jiggles” a little bake for 5-10 more minutes until he middle is totally set.
Remove form the oven and let cool for 10-20 minutes. Slice and enjoy!
Caramelized Onion & Spinach Quiche is the perfect breakfast item! It can be enjoyed hot or cold and makes great leftovers to eat on for breakfast all week!
