Where are all my quiche lovers out there??
I’ve always been a fan of quiche. In fact, I enjoy it for any meal of the day. I absolutely adore the rich and creamy custard. I also love that it’s such a versatile dish.
Not in the mood for mushrooms? Add broccoli or asparagus. Not up for a veggie quiche? Substitute with some meat. The possibilities are endless really.
Since it’s a rich dish, I don’t indulge often, but I actually feel better when I make this crustless version because I’m saving myself some calories, fat and carbs.
Crustless Mushroom Quiche Ingredients
- unsalted butter
- mushrooms
- shallots
- Gruyère cheese
- heavy cream
- milk
- large eggs
- Dijon mustard
- chives
- kosher salt and pepper
- Parmesan cheese
How to Make this Crustless Mushroom Quiche
You can use a deep-dish pie plate for this recipe or an oval baking dish like I did. You’ll just spray whatever dish you choose with some nonstick cooking spray and then sauté your mushrooms and shallots in a skillet in some butter until they’re nice and brown. I used white button mushrooms, but baby Bella mushrooms would work well too.
While the mushrooms and shallots are cooking you can shred your cheese and make your custard which is a combination of eggs, heavy cream, milk, Dijon mustard, chives, Parmesan cheese, kosher salt and pepper.
You’ll sprinkle the cheese and mushrooms in the bottom of your prepared dish and then pour the custard mixture over the top before finally sprinkling with some shredded Parmesan. The quiche will bake until it’s lightly browned on top and set in the center which will take about 35 minutes. It will need to cool for 5-10 minutes before you scoop onto plates and serve.
If you’re serving it for breakfast it’s delicious with some toast and if you’re enjoying it for lunch or dinner, a side salad would be perfect.
It’s no crust, no fuss and just delicious!

A Few Cook’s Notes for Crustless Mushroom Quiche
As I mentioned above, I used white button mushrooms, but you could use whatever mushrooms you like.
You can also change up the mushrooms if you’re not a fan and substitute another veggie, like broccoli or asparagus maybe.
Make sure you cook your mushrooms and onions until they’re nice and brown, so they’re not watery when you add them to your dish.

J’ai végétalisé ta recette pour ce midi !!!
Le résultat est bluffant !
J’ai remplacé lait et crème par du tofu soyeux et de la boisson non sucré au soja et j’ai ajouté un peu de curcuma pour la couleur et remplacer les œufs.
Nous apprécions les champignons, cette recette va être un coup de cœur.
J’adore à partir de recettes non végétales, les transformer à notre goût, et végane.
Merci beaucoup …
Si heureux que vous l’ayez apprécié! Nous aimons aussi les champignons dans notre quiche!
Can I substitute sour Cream for some of the cream?
I have only tested the recipe with the cream Randy, but if you give it a try let me know how it turns out.
This is absolutely delicious! I was a little nervous about the dijon, only because I have never used it in eggs before and I was serving it to a guest, but it complemented the gruyere wonderfully. Will be making this again and again- thank you!
You’re so welcome! I always add Dijon to our scrambled eggs too and we love it! So happy you enjoyed the recipe.
Made yesterday for brunch and it was a big hit. Almost “as written” except I didn’t have shallots, so used 1/2 regular onion instead.
So happy you enjoyed it Jilly!
Can I assemble this the day before and bake the next morning?
Yes. Since there is no crust with this recipe that would work. Enjoy!
It’s cooling, and smells wonderful!
Enjoy it Annie!!
Can this be frozen? Also, have you tried making it is muffin cups?
Hi Beatrice. Yes, you can freeze this. After you bake, cool the quiche completely, then you can wrap it in plastic wrap and then in aluminum foil. If frozen, it will keep for up to three months. To reheat it, just thaw it in the refrigerator overnight, then bake in a preheated oven until it’s heated through. Here is my recipe for some egg cups in a muffin tin, https://thebeachhousekitchen.com/sausage-egg-and-cheese-breakfast-muffins/ Enjoy!
Thanks so much!
Anytime Beatrice! I love that name!
