This Keto Quiche Lorraine is a delicious and creamy pie with a flaky crust, filled with a savoury egg custard with gruyere cheese and bacon.
With only 2g net carbs per slice it is sure to be a low carb favourite meal for anyone trying to lower their carb intake. A perfect diabetic friendly option without compromising on great taste.
My first time enjoying a quiche lorraine was in France and my jaw dropped after taking the first bite. I was so in love with this scrumptious pie. So I came up with a keto crust for this recipe by using a modified version from my Keto Butter Tarts recipe.
Main ingredients used
The first time I made this low carb quiche lorraine I could not believe how amazing it turned out. The custard like filling was creamy while the gruyere cheese (one of my favourite cheeses) just makes this dish the ultimate quiche.
- Almond Flour: keeping the carbs low, this pie is made with blanched almond flour.
- Bacon: adding that savoury bacon flavour to this quiche is optional but for me it's a must and really gives this low carb dish a pop.
- Onions: sauteed onions until soft releases the natural sugars, cooked until almost translucent.
- Gruyere Cheese: a little nutty, creamy but slightly sweet and salty. It's become a staple in my house.
The best keto quiche crust
This keto quiche crust can be used for many recipes that ask for a crust. The crust comes out super buttery and crisp every time I make it. It truly is the best keto pie crust I've ever had. No joke!
I use it for meat pies, coconut cream pies and pumpkin pies. No need to make the crust look like it came out of a BON APPÉTIT magazine. This is a rustic dish and the natural, aged and casual look is what makes this pie stand out from the crowd.
What types of cheese to use in a quiche?
If you know me, you know I love my cheese. I have my top 3 favourite cheeses below. All 3 can be used in this recipe but a white cheddar or swiss cheese can also work. However, I do think Gruyere is the best for this dish.
Comté is a French cheese made from unpasteurized cow's milk in the Franche-Comté traditional province of eastern France (Jura) bordering Switzerland and sharing much of its cuisine. This is also where we spend most of our time in France and where my partners family lives, so I may be biased.
Gruyère is a hard yellow Swiss cheese that originated in the cantons of Fribourg, Vaud, Neuchâtel, Jura, and Berne in Switzerland.
Dubliner is a sweet, granular cheese aged over a year and manufactured by Carbery, located in County Cork, Republic of Ireland.
I suggest watching the instructional video as there are many steps in this recipe. However, it's is not difficult once you observe how I made it. If you follow the ingredients and directions you will not be disappointed. If you love bacon, cheese and eggs, this quiche is for you!
Step by step instructions
How to make keto quiche lorraine?
- STEP 1: For the crust add the almond flour and salt to a large bowl and mix with a fork to combine. Add the cold butter and cream cheese, use two forks or a pastry blender to combine.
- STEP 2: Add the 1 large egg and apple cider vinegar, mix with a fork and then use your hands to shape dough into a ball. Wrap in plastic wrap and store in the refrigerator for 1 hour.
- STEP 3: Preheat the oven at 375°F. Remove dough from fridge after 1 hour and roll out to a 9" circle on a parchment sheet.
- Place an 8" pie pan over the rolled out dough and then flip so the pie crust is not sitting on the pan.
- Gently peel off the parchment paper and maneuver the pie crust into the pan, pinching the edges if desired.
- STEP 4: Bake the crust in the oven at 375°F for 10-15 minutes until golden brown around the edges. Set aside to cool for 10 minutes.
- STEP 5: Let's make the custard filling. First Preheat the oven to 350°F.
- STEP 6: Crisp up the bacon in a frying pan on the stove top and then transfer to a dish lined with paper towel. Set aside.
- STEP 7: Using the same frying pan saute the onion in the bacon grease and then transfer the onions to the quiche crust with half of the crisped bacon. Top with the shredded gruyere cheese and then the remaining bacon.
- STEP 8: In a large bowl mix the 4 eggs with the cream, cayenne and nutmeg and then pour over the contents in the pie.

Top Tip: if you notice the pie crust bubbling in the oven use a fork to poke the air out to flatten them. You may also want to poke holes in the dough before flipping onto the pie pan.
Cold Dough: try to work quickly when rolling out the dough out of the fridge as it will be more difficult to work with as it gets warmer.
How to store quiche?
Allow the low carb quiche to cool completely and then store on a dish wrapped in plastic wrap in the refrigerator for up to 4 days. Reheat individual slices in the microwave.
