Enjoy fresh flavors of sautéed mushrooms and wilted spinach for this savory spinach mushroom quiche recipe. Combined with rich flavors of nutmeg, olive oil, and salt, this quiche delivers flavors that are well-rounded and comforting–things we all love about quiche.

This breakfast quiche is great for the holidays when you are in need of a recipe that is quick and easy but does not lack any flavor whatsoever. This classic recipe is one that I make often because the steps are so easy plus I love quiche. 

I love to experiment with different styles of quiche such as this crustless bacon, spinach, and mushroom quiche or my quiche lorraine. Another thing I enjoy about homemade quiche is that there are just so many options and different ways to prepare it.


  • Flour: I like to use all-purpose flour because it is easy to work with and creates a crust that is perfectly crispy but soft at the same time. 
  • Pepper: You will need black pepper for the seasoning and to give this quiche extra flavor. Feel free to experiment with different types of peppers for some heat.
  • Salt: Salt gives this quiche its savoriness and is a great way to make a recipe stand out! 
  • Oil: I use extra virgin olive oil for this recipe, but you can use any kind of neutral oil. 
  • Milk: Use dairy milk or unsweetened soy milk for the creamiest quiche filling.
  • Mushrooms: Use any varieties of mushrooms such as portobello or button mushrooms. You can use shiitake, oyster, chanterelle, morel, etc. 
  • Spinach: Fresh baby spinach is great for this quiche or you can use the regular kind of spinach. Feel free to switch things up with different greens if you don’t have spinach on hand! 
  • Eggs: Eggs are the protein-rich filling for this spinach mushroom quiche and what makes this quiche so good. 
  • Nutmeg: Ground nutmeg is used to give the quiche a little bit of rich spiciness. If you don’t have ground nutmeg, then you can grate a whole nutmeg with a boxed or micro grater.

    • Whisk: This is my very favorite whisk because it is durable and easy to hold! I have more than one of these whisks in my kitchen!
    • Measuring Cups and Spoons: I love these stainless steel measuring cups and spoons because they are easy to clean and use! 
    • Skillet with a Glass Cover: This large skillet comes in handy when I need it the most. Oven safe with a handle that stays cool, this nonstick skillet allows you to cook basically anything!
    • 9” x 1.2” Pie Plate: Glass pie plates are great to use because they are easy to clean and are simple to use! I like to use glass dishes because they do not hold any food odors and are safe for the oven, microwave, and dishwasher.
    • Mixing Bowls: I have a set of glass mixing bowls in all sizes that I like to use. You can prepare so many things in them!

    How To Make It

    1. Preheat oven to 350 degrees Fahrenheit. In a medium bowl, whisk together the flour, salt, and pepper until well combined. Pour in the oil and milk until the mixture forms into a dough.
    2. Evenly press the dough in the pie plate making sure to press the sides and bottom of the pan. Transfer the crust to the oven and bake for ten minutes. Remove the crust from the oven and cool.
    3. To make the filling, heat olive oil in a large saué pan over medium heat. Add the sliced mushrooms and cook while occasionally stirring for seven minutes or until they begin to brown.
    4. Next, add the spinach to the pan and stir for two minutes or until the spinach wilts.
    5. Carefully spoon with spinach and mushroom mixture onto the baked pie crust.
    6. In a medium bowl, whisk together the eggs, milk, salt, pepper, and nutmeg. Pour the egg mixture over the vegetables.
    7. Bake the quiche in the oven for 45 minutes or until it is puffed and set.
    8. Allow the quiche to cool five to ten minutes before serving.

    What is the secret to a good quiche? 

    The secret to a good quiche is the perfect ratio of milk and eggs. We want to avoid a quiche that is too eggy, so this recipe uses only four eggs which allows it to be light and creamy. 

    Should quiche crust be pre-baked? 

    To avoid a crust that is too soft and gummy, then you will want to make sure you bake your crust until it is lightly crispy! 

    Can I make quiche filling the night before? 

    Yes, it is so easy! Just sautée the veggies and whisk the egg mixture the night before baking the quiche. Store in the refrigerator until ready to use.
