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.

Love the idea of making them into muffins!! So happy you loved them!! xo
i made this tonight to reheat and serve at a mother’s day brunch i’m hosting. i did use a gluten free crust (i think wholly pie), and because of that i was able to spread the filling between two crusts. bacon, carmelized onion, and gruyere is a great filling for quiche and this recipe did not let me down. i should know, because i went ahead and snuck a piece from the “spare” quiche.

haha always sneak an extra piece!! I’m so happy you loved it!! xo
Just for your info, my husband and I live in Switzerland – he is Swiss born and raised. Gruyere (with an accent over “e”) and Swiss cheese are the same!!!! But love oyur recipe!
You write: Gruyere cheese – looove me some Gruyere, but Swiss would be another good option!

Yay! I’m so happy you love it – it’s one of my favorite recipes 🙂 In North America Swiss cheese resembles Emmental cheese, has holes, etc. whereas Gruyere is made from whole cow’s milk, aged 6 months + has a stronger flavor, and doesn’t have holes usually. Gruyere is a type of Swiss cheese but not usually considered the same where I live.
Can I put this together the night before and bake in the morning??
