Main ingredients used
The first time I made this diabetic quiche, I could not believe how amazing it turned out. The custard-like filling was creamy while the gruyere cheese makes this dish the ultimate quiche.
- Almond Flour: keeping the carbs low, this pie dish is made with blanched almond flour. You can do half almond and half coconut flour.
- Bacon: adding that savory bacon flavor to this quiche is optional but for me, it's a must and gives this low carb dish a pop.
- Onions: sauteed onions until soft release the natural sugars, and cook until almost translucent.
- Gruyere Cheese: as a main ingredient this cheese is a little nutty, and creamy but slightly sweet and salty. It's become a staple in my house.
- Heavy Whipping Cream

The best low carb quiche crust
You can make a keto crustless quiche recipe but then it's just an egg pie. 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 and a great way to add a crust to any pie.
I use it for meat pies, coconut cream pies and pumpkin pies. This is a rustic dish and the natural, aged and casual look is what makes this pie stand out from the crowd.
Step by step instructions
How to make keto quiche?
STEP 1: First step, make the crust or pie shell. In a large mixing bowl, add the almond flour and salt 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 (room temperature) 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 to 375°F. Remove dough from the 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 pie crust in the oven at 375°F for 10-15 minutes until golden brown around the edges. Set the pie shell aside to cool for 10 minutes.
STEP 5: Let's make the egg mixture custard filling.
First, Preheat the oven to 350°F.
STEP 6: Crisp up the bacon in a frying pan or large skillet over medium heat on the stovetop and then transfer it to a dish lined with a 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 mixing bowl mix the 4 eggs with the cream, cayenne and nutmeg and then pour over the contents in the pie.
STEP 9: Bake on a baking sheet at 350°F for 50 minutes. A slight jiggle in the center indicates the perfect texture for this keto-friendly quiche. Allow to cool for 5-10 minutes for the custard to set. Slice and enjoy!
Recipe tips
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 it 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.
Recipe variations
- Cheese Please: Swap for different types of cheese like cheddar cheese, feta cheese or mozzarella.
- Meat Variations: Replace bacon with sausage, ham with chorizo, or chicken with smoked salmon for a protein twist.
- Veggie Options: Try spinach, kale, asparagus, or zucchini instead of broccoli or mushrooms.
Storage
Allow the low carb quiche recipe to cool completely and then store in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in the microwave.
