The Best Mushroom Quiche

This is the BEST mushroom quiche recipe made from scratch. You can also go semi-homemade and use a store-bought pie crust or puff pastry. The filling is soft, creamy and cheesy, flavored with garlic, nutmeg and Parmesan. A perfect make-ahead dish for entertaining whether it’s breakfast, 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 Mushroom 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 fresh herbs to add some flavor. While mushrooms can be eaten raw, sauteing the mushrooms is important so we evaporate all the excess liquids and have a wonderful creamy quiche. The best part? This mushroom filling can be made up to three days in advance and kept in the fridge until assembly.
• The custard mixture – This is what gives us a rich creamy and delicious quiche. Made with milk, eggs, some cream and cheese this is best made last, or up to a day in advance.

So, you see, this is a great quiche to make when you plan to entertain guests. On the day you need the quiche, assemble all the ingredients and bake as directed below.

Is it necessary to prebake pie crust?

I’m often asked this question. I know there are many recipes that don’t call for pre-bake. But honestly, the crust does taste better. It’s crisper and melts in the mouth rather than chewy. If you pre-bake the crust for 12 to 15 minutes and cool it for 10 minutes you will love the end result.

Homemade Pie Crust or Pâte Brisée

You can use a standard pie crust recipe, which I have shared in great detail with you. While I never discourage you from using ready to roll store-bought pie crust, I highly encourage you to try my homemade pie crust, which is surprisingly simple and easy to make. This results in a tender, buttery, yet crisp and flaky crust.

Let’s talk ingredients and substitutes (Save/Pin)

• Mushrooms – I have used white button mushrooms today, and yet any mushroom would work wonderfully.
• 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.
• Herbs – I love fresh cilantro but parsley works just a well.

Useful Tips and Tools

• A good set of baking pans such as quiche pans and pie pan is a good investment if you like baking. There are many good and affordable pans, but I particularly like the ones with high sides, so I have more room for filling and moving around. 
• A wooden barrel rolling pin makes for easy rolling, especially when working with pastry. I love using my French rolling pin for almost everything.
• Use a heavy bottom saute pan to caramelize the onions so they brown not burn easily. 
• It’s best to line the baking tray with aluminum foil for easy clean up especially when roasting veggies or things with oil. That way the baking tray won’t have burnt oil stains. 
• Use a Chopping board and Kitchen knife to chop the vegetables into small pieces.
• Every oven works differently. So the baking times are just guidelines. If things bake too quick or too slow compared to the time given it might be a good idea to check if your oven needs calibration. An oven thermometer is a great little gadget to help keep the oven temperature in check. All you need to do then is adjust the temperature accordingly.

• When chilled well – Dust the work board with flour.

• Use your pie pan as a guide to know how big you need it.
• When you reach the desired size – transfer the dough to the pie pan.
• Carefully make sure the dough is evenly spread in the pan.
• Cut the excess from the edges leaving a 1/2 inch for crimping.
• Fold the excess so you have a pretty round edge.
• Crimp the edge by forming a V shape with the thumb and index finger.
• Let cool in the fridge for 15 minutes.
• Preheat the oven to 190 C / 380 F.
• Prick the pie crust all over with a fork.
• Pre-bake the crust for about 10 to 12 minutes and let cool for a while.

Prepare the Mushrooms

• Wipe the mushroom with a clean kitchen towel and separate the stalks.
• Chop off the ends of the stalk and cut them fine.
• Slice the mushrooms and chop them into slices.
• Keep the chopped stalks and chopped mushrooms separate.

Prepare the Mushroom Filling

• Heat oil in a wide pan so the liquid evaporates faster.
• Saute the onions and garlic for one minute.
• Add the chopped stalks to the pan with the onions and garlic.
• Add salt and pepper.
• Once the onions are translucent add the sliced mushrooms.
• Cook the mushrooms on medium-high for about 7 to 8 minutes until all the water is evaporated. Remove from heat and let cool.

Assembling the Mushroom Quiche

• Add 1/4 cup of the cheese to the pre-baked pie crust.
• Followed by the mushroom filling.
• Pour the egg mixture over.
• Sprinkle the top with grated mozzarella and a little more Parmesan.
• Lastly, sprinkle the breadcrumbs.
• Bake in a preheated oven for about 35 to 40 minutes or until the quiche looks set.
• The center might still be a bit wobbly but that will set with the residue heat.
• Let cool so the egg mixture will set. That way you will get pretty neat and even slices.
• Serve as a side dish with a main meal or a breakfast or brunch treat.

Storage

• Once baked, let the quiche rest for at least half-hour before serving. 
• Store any leftover quiche in the refrigerator wrapped well in cling wrap to prevent drying out. 
• This quiche can be frozen for a month and can be baked from frozen at 370C / 350 F for about an hour. If necessary tent with foil to prevent the crust from getting too brown.
