Eggs are a staple in our house. I like to call them a pantry staple, and you know what I mean.

When I think about how to stock a pantry and fridge for the first time, they are one of the core ingredients!

You can do so much with eggs, and they are a superstar ingredient. Read more about egg nutritional benefits, and why!

They are a great addition to any meal or entree, any time of day, plus they’re great for babies, kids and adults. 

I know people tend to worry about allergies, but newer research points to introducing allergens earlier for babies and kids.

We love making scrambled eggs, or using them as a base for french toast for babies. 

Since eggs are a staple, we often use them in savory recipes that work well for lunch, like this sweet potato egg casserole or skillet breakfast scramble.  

Why You’ll Love This Mushroom and Asparagus Quiche

• A great stand alone for brunch or side – If you’re a pancake lover and always find yourself wondering what to serve with pancakes, this mushroom quiche is superb. A savory side for something sweet.
• Full of veggies – It’s nice to get veggies in for breakfast, with mushrooms and asparagus. Start the day off strong!
• High in protein – Thanks to the eggs and cheese, this mushroom asparagus quiche is also a great source of protein!
• Easy way to use up old veggies– If you have veggies on their way out, like wilted spinach or soft peppers, this asparagus and mushroom quiche recipe is a great way to prevent food waste.

Ingredients

This healthy veggie quiche recipe uses storebought crust (save yourself the time!) and fresh veggies for a delicious result the whole family will love. 

• butter – use olive oil or coconut oil to keep it a dairy free quiche recipe)
• asparagus
• mushrooms
• peas (fresh or frozen)
• salt
• Italian seasoning
• black pepper
• garlic
• eggs – I use Egglands Best because they have higher amounts of Vitamin D, omega 3 fatty acids and B12 compared to other egg brands
• cheese (I used mozzarella and sharp cheddar)
• pie crust – make your own, or use storebought like I did

This asparagus and pea quiche is veggie loaded without noticing. Asparagus is so underrated – it’s amazing in this quiche.

You can even throw it in broccoli and asparagus salad.

How To Make An Asparagus and Mushroom Quiche

Let’s first start by saying I’m all for storebought pie crusts and shortcuts.

With two three young children and a business to run, this is a shortcut I think is totally worth it for me. 

And the end result of this roasted asparagus and mushroom quiche is still crispy and buttery and all sorts of delicious. 

Because they’re nicely immersed in a warm, cheese and eggy coating. Better yet, you only need to devote about 10 minutes of prep time.

If you’re using a premade pie crust, unroll it onto a 9-inch pie plate (I love this one because it’s pretty and it has ridges).

In a large skillet, melt your butter and add cut asparagus and mushrooms, or any combination of vegetables you are using.

Then add your frozen peas and spices. Just toss them all in there, give them a mix, and allow the heat to work. 

Separately, whisk your eggs and add to the cooked veggies in a small bowl. Pour the mixture in the pie crust (if using).

Top with cheese and put it in the oven for 40-45 minutes and then enjoy!

If you want to freeze quiche, see below for directions!

Other veggie add in’s and topping options to include are red peppers, onions, spinach, kale, zucchini or squash.

Add in protein – You could also add bacon, ground pork or another source of protein!

A bacon mushroom quiche or asparagus and bacon quiche would be delicious.

I also love the idea of throwing sausage in there, like this turkey sausage breakfast casserole.

FAQ and Recipe Notes

• To make dairy free quiche: To make a dairy free quiche, leave out the butter and opt for your favorite oil, and swap out the cheese for a non-dairy version. 
• To make a crustless quiche: Yes, follow the same instructions without using a crust to make this crustless asparagus mushroom quiche.
• To pre-make quiche ahead of time: You can bake this easy vegetarian quiche recipe ahead of time and then chill it and have it available to reheat the next day. You could also technically make the filling ahead of time and store it in the fridge (few days max) until you’re ready to bake! 
• To freeze quiche: You can freeze quiche either before or after baking. If freezing after baking, allow it to fully cool and then wrap foil or saran wrap over the quiche. I like to add it to a freezer bag to protect it a little more. Make sure you squeeze the air out! When rebaking, bake for 15-20 minutes or until heated through, at 350-400 degrees.  For unbaked frozen quiche, add 15-20 minutes to the total cooking time. They make the best freezer meals for new moms!
