This vegetarian Florentine quiche is a classic made with an easy pie crust filled with mushrooms, spinach, cheese and eggs. It’s a simple and delicious French meal! Perfect for brunch, lunches, dinner with a soup and even breakfast if it is your style!
Quiches might seem like an intimidating dish but it is actually simple. This a great vegetarian version, if you are want some ham, the quiche Lorraine is your next option, it is a ham and cheese quiche. Also on the blog, there is also goat cheese spinach quiche.
Below, you will learn that making your own pastry crust from scratch is a life skill. You will never buy a pre-made one ever. Then, spread some mushrooms and spinach on your pastry crust. Finally, pour your egg, cream and milk mixture on it. You’ll be so proud when you are done with your spinach quiche!

How To Make The Pie Crust For The Florentine Quiche?
Try it once, make it always and forever! This is my weekday recipe you guys. So simple!
1 – Prepare all your ingredients, which are only 3, well 4 if you count the salt!
2 – Mix the butter and flour together until it crumbles between your fingers (see below).
3 – Gradually add the water until the ball is smooth. Don’t overwork the dough! That’s it, it’s ready to be rolled.
TIP: “My butter is not soft, it was in the fridge”: Take your cheese grater and grate your butter. Boom!
ANOTHER TIP: When I’m a rush, I spread the crust down directly in my pie dish using the palm of my hand. I’ve managed to make a pretty uniformly spread crust over the years!
1 – Ingredients 2 – Crumbles 3 – Ready to be rolled

How To Prepare A Florentine Quiche?
Now that you know how to make the crust, the next steps will seem really easy!
Cleaning your mushrooms: With a humid paper towel, clean your mushroom and slice the bottom of it. Slice them up and that is it! As a short cut, you can buy them already cut.
Wash your spinach and chop them grossly, I like it better when it’s cooked. Personal preference.
Sauté both in a hot pan with some olive oil. Add some salt to taste, not too much. You can skip the salt here if you want and just add it to your eggs. I prefer to do the latter.

Let’s talk dairy… Back home, in France, I would use crème fraîche, not sour cream. It’s not the same.
I would also go sometimes for just milk. Always on hand, less fatty.
BUT, I have since then, adapted and made my own version. I still use milk and same amount of heavy cream. I love the texture! A good ratio is one egg for a 1/4 of a cup of dairy.
Whisk the eggs, add in the milk/cream mix. Then, add salt and pepper. Sprinkle with some cheese of your choice and ready to pop in oven.

Can You Freeze A Florentine Quiche?
Absolutely! As a matter of fact, I would recommend it. I often make double the batch and freeze for later.
Shall I freeze my quiche cooked or uncooked? Either way! Bake your spinach quiche 10 minutes less than required, let it cool and then freeze. Alternatively, you can freeze your quiche uncooked BUT you need to make sure it nicely flat in your freezer. Once frozen, you can store it in another position.

May 23, 2020 at 12:24 amThis looks gorgeous! I always make my own pastry – I usually put the butter in the freezer for a little while before grating, and dip in flour as I go, so it makes it easier to grate! With fresh eggs and my own pastry, I do not know why I don’t make quiche much more often!

May 23, 2020 at 4:12 pmI like quiche but have never baked it myself. I would love to try your recipe. My inlaws are visiting and they don’t eat eggs. What can I substitute for eggs?
