You are going to LOVE this crustless caramelized onion and bacon quiche.
I love a good quiche. It may sound weird but it’s my go-to for special occasions. When people have a baby? Quiche them. When there’s some brunch I need to attend? Bring a quiche.
It’s one of those recipes that you can keep in your fridge and cut off slices to heat up as you want.
This quiche is LOADED with all my favorite flavors and is such a decadent breakfast or brunch everyone will love!
Ingredients for this low carb quiche:
- Refined coconut oil – butter, ghee or your favorite cooking oil also works!
- Sweet onions
- Whole grain mustard – this is the secret ingredient. I know it feels a little weird, but just trust me on this!
- Eggs – it is a quiche after all!
- Heavy cream – makes it sooo creamy and decadent, but you can sub in any milk here that you prefer.
- Gruyere cheese – looove me some Gruyere, but Swiss would be another good option!
- Bacon – I mean… enough said. But, if you want ot make this a vegetarian quiche, but all means, you can leave it out!
- Nutmeg – adds a surprising warmth and coziness to the quiche!
- Salt and pepper
How to make the most delicious crustless quiche:
Cook onions in coconut oil over medium heat for 20 minutes. Cover the pan and stir every five minutes. When the onions have five minutes left to cook, throw in the bacon.
In a large bowl, combine the mustard, eggs, cream, and Gruyere. Set aside a tablespoon or so of Gruyere to sprinkle on the top.
In a pie dish, place half of the onion and bacon mixture. Using a spoon, spread it evenly on the bottom of the dish.
Then, pour the egg mixture. Top with remaining bacon mixture, using a spoon or spatula to dip/press it into the egg. The dish will be much fuller than the picture illustrates.
Sprinkle top with remaining cheese, a couple pinches of nutmeg, salt, and pepper. Pop it in the oven.

Let me know how much you love this in the comments below!! xo
Big Hit!! I made one with a crust and one crustless. A couple of pantry changes: I used shallots in olive oil and added broccolini. Dee-lish!
★★★★★
Sounds so delish!! I’m glad you enjoyed!! xo
Am I able to make this ahead and freeze it or stick it in the fridge?
If I freeze it should it be before or after it cooks? I’m planning a girl’s weekend and I want to make breakfast an easy thing instead of having to wake up and make it.
Honestly I don’t know about freezing it, I’ve never tried! I’m a little worries it may get icy, but if you give it a shot, let me know how it goes!! xo
This recipe is one of our favorites, we always make it with crust. We have started to do an “onion medley” by caramelizing red onion, yellow onion, and shallots. This recipe is our happy food!

Loooove the idea of onion medley! I can’t wait to try it!! xo
I NEVER comment on blogs, websites, forums whatever, but I was compelled to get the word out about the deliciously awesome recipe. So so so good!
Made it this morning for Christmas brunch and everyone loves it! You’ll be scraping the sides and bottom eating every morsel you can find. Thank you for sharing!

Yay!! Thanks so much for your comment!! I’m so happy you love it – it’s one of my faves!! xo
I sautéed in GF butter instead, added cognac right before the bacon let that absorb a few minutes then added the bacon and turned up on high to crisp up for about 7 mins. I used 1/2 amount of mustard and mixed in nutmeg, salt, pepper and all cheese (by accident). Follow instructions for layering but used a pate brisee crust that I baked off yesterday. Had to bake about 40-45 minutes to set – last 20 minutes st 375. Every oven is different lol!
I also used equal parts smoked gruyere and regular gruyere.
EXCEPTIONAL
