Who is Lorraine and how did she come to have a quiche named after her? I have no idea but I know how much I love this recipe for Paleo Quiche Lorraine. Breakfast, brunch, lunch, dinner – it’s good anytime of the day. And it has bacon.


This Paleo Quiche Lorraine has a wonderful sweet potato crust and only uses egg whites, so it is so much healthier for you than traditional quiche! Love it.

I love bacon.

So, how do we make quiche, a brunch staple for decades, into a Paleo-friendly dish? Well, first instead of a crust made out of wheat flour, we make our crust out of sweet potatoes. Aside from being just plain old Paleo-friendly, this substitution adds vitamins and minerals to the crust that you’d never get from a traditional wheat flour crust.

One of the notable ones is vitamin A, which gives a sweet potato its gorgeous red-orange color. Plus sweet potatoes are packed with fiber – something you’d get almost nothing of in a regular wheat crust.

Make sure you peel the sweet potato before you shred it. It won’t be horrible if you don’t, but it’s a little more tasty without the skin. Once it’s peeled, go to work shredding that baby. I use an attachment on my food processor to shred veggies like sweet potatoes, but you can also use a good old-fashioned stand up shredder.

egg whites

The egg white and the almond flour (instead of not Paleo-friendly wheat flour) will bind the sweet potato shreds together. Don’t forget to add these two critical ingredients before pressing your sweet potato into the crust shape. If you neglect to put these two ingredients in, you’ll end up with a crust that doesn’t stick together after baking! And that’s not a very good crust.

But with the egg white and almond flour included, the sweet potatoes will form a crust to keep all the other ingredients in their pie-shaped form. Normally, quiche Lorraine is made with bacon and cheese, with milk or heavy cream whipped into the eggs. We love the egg part. Eggs are packed with protein! But since Paleo recipes stay away from dairy, we’re substituting cashews, blended until they are smooth, for the cheese and milk product.

The blended cashews will give the egg a silky consistency and will keep the quiche from tasting just like plain eggs. Plain eggs are fine and dandy, but we’re taking eggs to the next level here!

And, of course, the bacon just takes everything up yet another notch. I recommend using nitrate-free bacon. It’s a little more expensive to get all natural cured bacon, but the taste is phenomenal and the health benefits are worth it.

Just like other folks, I like to serve my Quiche Lorraine at a brunch with friends. They appreciate the unique sweet potato crust, even if they aren’t Paleo eaters, and they never guess that their quiche is packed with the protein and fiber of cashews. So serve this on up with a side of berries and you’re ready for your next brunch.

    • 1 egg white
    • 2 tbsp almond flour
