An easy low carb crustless quiche with mushroom with perfect custard texture and nice rich flavor. It’s a great breakfast option for rushed mornings or a nice lunch with a friend. Low carb and ketogenic recipe.
I have some stand out quiche recipes on this blog – my most popular being a easy crustless quiche with spinach and bacon. Then, I have two large quiche recipes perfect for brunch: Ham Quiche Lorraine and Ham and Arugula Quiche. If you need something portable, check out the spinach feta quiche muffins. They taste amazing – really. But, if you are looking for a mushroom quiche with a luxurious custard texture and a rich smoky flavor, this is the one.
Now, I admit to being a mushroom lover. I love them stuffed with spinach artichoke dip. and as a base for super cheesy portobello burgers. I even love them sauteed in butter and thyme or even a good green bean mushroom saute. Tossing mushrooms in Indian spices and roasting them in the oven is sublime. You see where I’m going here? I have a lot of easy mushroom recipes on the blog.
There’s something special about the flavors in this low carb crustless quiche with mushroom recipe. Usually, I’ll add a little fresh ground nutmeg and thyme to a quiche recipe like this. However, keeping the ingredients to a minimum this time let each ingredient shine.
I’m sure we can all agree that quiche with a flaky crust, even a nice low carb crust, is a beautiful thing. But sometimes I just want an easy quiche recipe and that means crustless! Who wants to fool with making a crust for quiche every time? Not me. And nixing the crust keeps it low carb and lower in calories.
This easy low carb crustless quiche is full of mushrooms, sauteed onions, and smoked gouda cheese. Layering the ingredients in the dish prevents them from sinking to the bottom, ensuring an even distribution of ingredients throughout the custard. The salty-buttery smoked gouda cheese provides enough richness that the crust won’t be missed.
[TIPS] If you want to bump up the flavor saute the onions with a sprig of thyme or some white wine. It will produce a subtle flavor that won’t overpower the delicate custard. Adding just a little grated nutmeg lends a sweet-spicy flavor which enhances the richness of flavor. Lastly, the addition of Dijon mustard (1 tsp) adds a little sharpness to cut the richness of flavor.

- 8 ounces sliced mushrooms (white or brown)
- 3 tbsp butter, divided
- 1/4 cup shallot or onion, minced
- 5 large eggs
- 1 1/4 cup heavy cream
- 1/4 cup water
- 4 ounces smoked Gouda cheese
- 1 tbsp snipped chives
- 1/2 tsp salt
- 1/4 tsp black pepper

Preparation: Preheat oven to 375 and place rack to the middle position. Spray a 9-inch pie dish with baking spray. Mince the shallot or onion. Snip the chives. Grate the cheese.
-
Method: Heat a saute pan over medium heat and when hot, add 2 tbsp butter and the sliced mushrooms. Stir to coat the mushrooms. Saute for two minutes, then stir and saute 1-2 minutes more or until some of the moisture has been removed. Transfer to a small plate to cool.

Place the saute pan back onto medium heat and when hot, add 1 tbsp butter and the onions. Stir to coat the onions and saute until softened. Remove from heat.

Add the eggs, heavy cream, water, salt and pepper to a medium bowl. Beat at high speed until combined and frothy.
-
Layer: Add 1/3 of the cheese to the bottom of the pie dish, spreading it so that it is even. Arrange 1/2 of the onions, 1/2 of the mushrooms and 1/2 of the chives evenly over the cheese. Add another layer of cheese, followed by the rest of the onions, mushrooms and chives. Slowly pour the custard over the ingredients. Top with the remaining cheese.
-
Bake: Bake for 15 minutes at 375, then for 15 minutes at 350 or until the top is browned and the middle is just set. It may puff up a bit. Let cool to room temperature before serving or cover (after cooling) and refrigerate until needed.
Serves: 6

NOTE: If you have a convection oven or a hotter oven, you may need to adjust cooking temperature and time.
I used what I had on hand. Half and Half, a shredded mix of cheddar/gruyere/asiago and a Kraft creamy melts cheddar jack mix. Green onions, mushrooms and some left over breakfast sausage (wanted meat in the mix). I didn’t add the water because I was worried about it being too watery with using the odd mix of cheese. Oh and I used bacon grease instead of butter (I save it just for something like this). And because I don’t have a pie dish I used a cast iron skillet. It was amazing. I needed a recipe to give me confidence to try this! Yummmmm Ohhhhhhhhhhhhhh
Thanks for a DELICIOUS recipe. I’ve made it twice now. My only complaint the first time was that there was liquid puddling after you take a slice out. The 2nd time I made it, I left out the 1/4 cup water and there was no puddling. Big hit at my brunch the other day.
Hi Norma. I’m glad you like the recipe. The only thing I can think is that your mushrooms had some moisture left in them which they released while cooking. I’m glad your were able to correct the problem by omitting the water in the recipe. Thanks for taking the time to let me comment and share your tips. Enjoy your day. -Kim
This quiche is wonderful, Kim! I recently found out I’m diabetic and this will be a great addition to my new diet.
I’m so glad you enjoyed the quiche, Karen. Just so you know, any quiche can be cooked without a crust and will take anywhere from 35-60 minutes to cook depending on how many eggs and cream are used. You can also experiment with your fillings following the ratio of 1 egg, 1/4 cup cream, and 1 oz cheese. Sometimes I cut back on the cream a but by using water. Others use unsweetened plain almond milk. Thanks for taking the time to leave a comment and rate the recipe and I wish you luck in finding recipes that make your low carb journey easier. Take care. -Kim
I made this and it is to die for, it’s so good! Can’t wait to pick up some more mushrooms to make this again!
I’m so glad you like it, Elaine.
The cheese says 1/3 and another layer so I assume another 1/3.. Where’s does the last 1/3 go? Great recipe I’ve made it before with Cheddar and loved it but I don’t remember what I did last time.. This time I got smoked gouda to try
Thanks for letting me know that the instructions were unclear, Minaskshi. I revised it to say to add the remaining cheese on top before baking. I hope this helps. Have a wonderful week. -Kim
Absolutely divine , thanks!
Jennifer
I’m so happy you liked it, Jennifer! Enjoy your week. -Kim
Aa a Quiche a holic Id lije to share that I use Six eggs and add the cream and sour cream, or ff plain yogurt it helps keep the creamy texture and btw smokey gouda is my very fav. I have been known to make a family birthday with six diff flavored quiche. We are
Just gluttons for it. I do not geel as guilty when I make without the crust. If I am not on keto I use both cream and knudsen whole buttermilk. I was sad to learn that it is relatively high in carbs
Thanks for sharing your tips, Sandy! Have a great week. -Kim

My wife will be making it today, It would be great to have the NUTRITION FACTS per 100g, or to know the weight per serving.
Thank you so much !!
Hi Daniel. I did not weight the slices, I just divided the quiche evenly into 6ths. I would have to make the quiche again and weigh the finished product (minus the weight of the pie plate) to get the information for you. Is there any particular reason why you need the nutrition facts for 100? It would help make me aware for future recipes. P.S. This quiche is very good. I hope you enjoy it. -Kim
Could you please provide the rest of the calorie/protein/carb information for this dish?
Is it not there? I’ll check. Turning on the computer now. -Kim
I’m not sure what happened Mary. Sorry about that. The amount of fiber is “trace” grams and I can only enter numbers, so I left it out. Enjoy the recipe. -Kim
Hi Kim, I made the quiche for dinner last night! Absolutely amazing! Sadly no leftovers. Husband and kids approved!! ?
Fantastic! Thanks so much for taking the time to let me know how your family liked the quiche. Have a joyous weekend. -Kim
Thanks I have been looking for good recipes and this site looks great going to make the mushroom quisch 🙂
Great. I hope you like it Andrea. Have a nice day. -Kim
Hi there: Looks great …but just wondering if something other than Heavy Cream could be used …? and not sacrifice richness? Would buttermilk work in your opinion? I’d like to make up any potential dairy fat deficiency with an elegant salad with nuts ….?
Hi Lizzie, what about half-n-half. Buttermilk might be good, but it is sour. Maybe half 1/2 and 1/2 and half buttermilk? I didn’t test with those ingredients so I’m not sure how it would taste. -Kim
Thanks for the half-and-half/buttermilk suggestion. We really like the tang of buttermilk which I think will accentuate the flavor of the smoked gouda. Happy camper here.
Great!
Carb count please….
Hi Judy, it says in the post just above the recipe – 5 net carbs per serving and I just added it to the nutritional info. I don’t know why it wasn’t listed there. Sorry about that. Thanks for letting me know it was missing. -Kim
What’s a good substitute for the smoked gouda? I have all the ingredients at home except that! Grr. Would mozzarella work okay?
Chris, you could use the mozzarella, but it doesn’t have much flavor. Swiss or cheddar would work, too, but try the smoked gouda next time – it really makes a difference in the flavor and texture. -Kim
How many eggs? This looks divine!
Oops! Thanks, Donna. It was 5 large eggs. I just added them to the ingredient list. I hope you like the recipe. Have a wonderful evening. Kim
