You can serve it up at brunch or eat it for lunch or dinner, so give this recipe for crustless quiche a try the next time you want to prepare something special. I promise it’s worth the effort!

What is Crustless Quiche?
Isn’t a “crustless quiche” just a frittata? Nope! While they are both baked egg dishes, there are distinct differences. The main difference is the texture. Quiches are a custard made with egg, cheese, and milk or cream. They have a soft, delicate texture. Frittatas, on the other hand, contain little to no milk or cream, so it is closer in texture to an omelet or baked egg. The other significant difference comes in the cooking process. Frittatas start on the stovetop and only finish for the last few minutes in the oven. Quiches are baked in the oven only.
Can this crustless quiche be reheated?
Yes, this crustless quiche recipe is one of my favorite make-ahead breakfast dishes! But you do need to be cautious while reheating because overheating can cause the egg proteins to seize up, expel water, and become rubbery. For that reason, I suggest reheating in the microwave only until the crustless quiche is warmed through but not piping hot. This will store in the refrigerator for about 4 days.
Can You Freeze Quiche?
Egg dishes like crustless quiche freeze just so-so. This is one of those grey areas where it will depend a lot on how sensitive you are to texture changes. The egg in the crustless quiche will seep a little water upon freezing, thawing, and reheating, which may or may not bother you. I suggest testing this with one piece of the spinach crustless quiche first to see if the changes are acceptable to you. To freeze, cool the quiche in the refrigerator first, then wrap tightly in plastic and transfer to the freezer. Thaw in the refrigerator overnight before reheating.

How to Make Spinach and Mushroom Crustless Quiche – Step by Step Photos
Preheat the oven to 350ºF. Thaw one 10oz. block of frozen chopped spinach (I use the microwave), then squeeze out as much of the moisture as possible. The spinach should be fairly dry after squeezing, no water remaining in the bottom of the bowl.
Slice 8oz. of mushrooms and mince one clove of garlic.
Add the mushrooms to a skillet with ½ Tbsp cooking oil, one clove of minced garlic, and ⅛ tsp salt. Sauté the mushrooms until they release all of their moisture and it has evaporated off the bottom of the skillet.
Brush another ½ Tbsp cooking oil over the inside surface of a 9″ pie dish. Layer in the sautéed mushrooms, squeeze-dried spinach, and 2oz. crumbled feta.
Next, make the savory custard. Whisk together 4 large eggs, ¼ cup grated Parmesan, 1 cup milk, and ¼ tsp pepper.
Pour the custard mixture into the pie dish over the spinach, mushrooms and feat. Sometimes I like to use a larger baking tray to transport my pie plate in and out of the oven. I feel like it makes it a little easier to do without spilling, but that’s up to you.
Top the unbaked quiche with a little shredded mozzarella. You don’t need much, I only used about ½ cup or ¼ off an 8oz. block.
Bake the quiche in the preheated 350ºF oven for about 50 minutes, or until it’s golden brown on top or until the internal temperature reaches 160ºF.
Slice and serve warm!

I would love nutritionals! Please post them with your recipes if at all possible!
seriously, thanks for sharing such an awesome recipe. I just made this and it tastes amazing!
Jenerosity – Unfortunately, I have no experience cooking with almond milk :( My guess is that it would work, but I can’t say for sure.
I only have almond milk at home, could I use this?
I’ve been famous for lousy quiches, and I LOVE quiche, so I thought I’d give it a go! It was delicious, and turned out properly!! I used what I had on hand, fresh spinach, onion, garlic, mushrooms, zucchini, onion, red pepper, garlic, lowfat cheddar cheese, bacon, and parmesan cheese. (I even forgot the milk) I think the fewer eggs than most recipes was the golden ticket!
Anon – I’m really not sure about coconut in this recipe as it has different properties than regular milk… Also, it might give a strong flavor and I’m not sure how that would work with the rest of the flavors. But hey, experimentation often results in magical discoveries. Go for it!
would coconut milk be okay to use?
I think coconut could taste ok as a flavor, especially if you used a Vidalia onion and some nutmeg, but not sure how it cooks. I overhead a barista in Starbucks warning a customer that coconut out milk in a latte is flatter than regular milk. so I am wondering if you would get that puff that makes quiche yummy.
Found this through Pinterest and made it today. So delicious–thanks :)
I can’t wait to make this! My husband is on a low carb diet so we all can eat this!! Thanks!
Made this for dinner tonight and it was delicious! I am curious to know if anyone has figured the calories per serving.
I’m making this right now. Just put it in the oven :) I’m excited!! I never liked the crust part on quiche. now to make quinoa bites :)
How many calories per serving?
I just did the calculations and it’s 150 calories if the quiche yields 6 portions…
Hey! Thanks…do you know how many carbs per serving (slice)?
Delicious! Thanks so much!
Made this for lunch with my 3 year old helper. We served it up with seasoned pan fried potatos from Mamaw’s garden. Love Budget Bytes!!!
