Apple Leek and Brie Quiche (Keto)

Quiche has been one of my favorite foods for as long as I can remember. However, it wasn’t until my early 20s when I had a proper, creamy quiche from a local French bakery. Since then, I’ve been trying to find the perfect ways to bake a quiche at home. This recipe is a keto adaptation from the Duchess at Home  cookbook . This Apple Leek & Brie Quiche uses a small amount of apples for subtle sweetness while still keeping the carbs low. We pair this with our Savory Keto Pie Crust for a rich and elegant dish.

This recipe is intended for a large 9-inch deep pie dish. If you’re using a regular pie dish you’ll only need 1 batch of our Savory Keto Pie Crust and you will have some filling leftover. It’s important to note that this will impact the cooking time. Keep an eye on your quiche around 45 minutes, being careful not to overcook it. 

To Start: 

Begin by washing and trimming 1 leek and thinly slice. In a pan, sauté the sliced leeks with butter until caramelized. This will take approx. 10-15 minutes. Once caramelized, the original recipe calls for 1/2 cup of French cider. To lower the carbs, I’ve reduced the cider to 1/4 cup. You can also use unsweetened apple juice (this is what I use and love the result). The apples and juice in this recipe are very minimal, so the total carbs are well within a keto diet. Once the juice or cider as reduced, stir in the diced apples. Below is what the filling should like once these steps are complete.

Keto Adaptations: 

Along using our Savory Keto Pie Crust, we made a few other adaptations to make this Apple Leek and Brie Quiche to fit within a keto or low carb diet. The original recipe uses Camembert Cheese, however we use Brie which is very similar. Brie has a more mild and buttery aroma compared to the earthy scent of Camembert. You can use whichever cheese you prefer. The original recipe calls for 1/2 cup of whole milk, which we have swapped out for unsweetened almond milk. This adds a nice lightness to the filling. 




When baking the quiche, it’s important to cover the edges of the pie crust with aluminum foil. Since the crust is made with almond flour, it can burn quite easily.  Baking time will also vary depending on the size and material of your pie dish. I suggest to start checking your quiche at around 45 minutes. I use a ceramic pie dish and my oven is slightly older, I need just over 1 hour to fully cook the quiche. Check to see if your quiche is set by sticking a toothpick in the middle. If it comes out clean, it’s done. Be sure not to overcook your quiche. If you do, it won’t be as creamy as it should be. I actually prefer to slightly undercook my quiche by 2-3 minutes, especially if I know that there will be leftovers. Once done baking, let the quiche cool for about 10-15 minutes. This will help the filling settle and your slices will come out clean without the filling falling apart.
