This is the BEST mushroom quiche recipe made from scratch using homemade pie crust. The filling is soft, creamy, and cheesy, flavored with garlic, onions, and cheese. A perfect make-ahead dish for entertaining whether it's breakfast, brunch, lunch, or dinner.
With the number and variety of quiche recipes I have on this blog, it's fairly obvious that I love quiche. And this mushroom quiche, I must say, is a big family favorite. It has everything everybody in our family loves!!
While most kids don't warm up to mushrooms, my kids love mushrooms. In fact, this is Aadi's favorite quiche.
About this Quiche
I think a mushroom quiche is a great make-ahead dish. It's not just delicious, it's also quite impressive. Many people don't make the effort to make quiche at home. And yet, if you plan it in advance, you are sure to impress your guests and score some points.
There are three components to this mushroom quiche.
- Pie crust - You can either buy ready to use pie crust, which is available in most supermarkets these days or make your own pie crust from scratch. Did you know that you can make the crust and save it in the fridge for up to 2 days? Or freeze it for a month in the freezer?
- Mushroom filling - This filling is just a simple saute of mushrooms with onions and parsley to add some flavor. Sauteing the mushrooms is important so we evaporate all the excess liquids and have a wonderful creamy quiche. This filling can be made up to three days in advance and kept in the fridge.
- The custard mixture - This is what gives us a rich creamy and delicious quiche. Made with milk, eggs, cream, and cheese this is best made at the time of assembly and it takes just 5 minutes
I know there are many recipes that don't call for pre-baking the pie crust. But honestly, the crust does taste better when prebaked. It's crisper and melts in the mouth rather than chewy. If you pre-bake the crust for just 12 to 15 minutes and cool it for 10 minutes before you add the rest and baker further you will love the end result.
Ingredients and substitutes
- Mushrooms – I have used white button mushrooms today, and yet any mushroom would work wonderfully. I think a combination of mushrooms works great too.
- Breadcrumbs – A light sprinkle of breadcrumbs on the top prevents the cheese from burning and adds a nice little crust as well.
- Cheese – The Parmesan adds a nice nutty flavor, while the Mozarella helps hold everything together. The cheddar, Grueye or Emmental adds a nice sharpness to the quiche.
- Onions – I love to use onions for extra flavor, but you can omit it altogether. If you do use onions, I highly recommend you saute them to take the raw bite and pungent flavor.
- Garlic – A little goes a long way and it does add tons of flavor.
- Parsley – I love parsley in my quiches but cilantro or similar work too.

Frequently Asked Questions
Most quiches, including this one, can be made a day or two ahead of time and kept in the refrigerator. Alternatively, you can make the pie crust beforehand, mushrooms filling as well as custard filling and keep them in the fridge. On the day or morning an hour or two before brunch - assemble the quiche and bake it fresh. It is impressive to bring a freshly baked quiche out of the oven in front of guests.
Yes, as you can see I have used milk and cream in the custard mixture. If you want to omit the sour cream you can add a tablespoon of flour or cornstarch. The starch acts as a thickening agent, so the quiche cuts into beautiful wedges despite using milk.
Yes, you can. In fact, I have a wonderful mushroom ricotta cheese tart that is very popular too.
I usually serve all my quiches warm because I don't like fridge-cold quiche. And yet, oven-hot quiche won't make impressive wedges either. As a guide, I let the quiche cool for a good half hour before serving. The egg mixture cools just enough so it cuts into beautiful and impressive servings.
You can store any leftover quiche wrapped well in the fridge. You can also heat it in the microwave, and yet the crust tends to get soggy. For the remaining few slices, this is ok. If I have a large piece of quiche leftover, I prefer to heat it in the microwave for a minute, then place it in a hot oven, for 8 to 10 minutes, until the crust gets crisp again.
Frozen quiche can be baked in the oven from frozen for about 45 minutes to an hour at 170 F or 350 F.
