I love mashed potatoes. After my Celiac Disease diagnosis, they became my go-to comfort food. Little did I know they could be turned into the base for a Mashed Potato Crust Quiche!
Perfect Dish for Holiday Leftovers
You could make this Mashed Potato Crust Quiche any time of the year. However, I find it most handy right after the holidays. I always make extra mashed potatoes, because they can be re-purposed in so many ways. After Thanksgiving or Christmas, there’s usually lots of turkey or ham left over. With your potatoes already mashed and your meat already cooked, throwing this quiche together is a snap!
How to Use Mashed Potatoes to Make A Crust
Of course, you can make this any time of the year. The mashed potato crust is easy to make. If you don’t have leftovers, just wash, cut and boil 3-4 potatoes. Once they’re fork tender, drain the water, mash and season to your preference. (I add butter and a bit of goat cheese to mine. Yum!)
Make sure the potatoes are cooled enough to work with, so you don’t burn your hands. Form the mashed potato crust into a pie pan and brush with oil. Bake in a 350 degree oven for 30 minutes, just until it starts to get golden brown. Then take it out and bump the oven to 375.
What’s the Ratio of Egg to Milk to Make A Gluten Free Quiche?
I don’t make quiche often, so I researched a few different recipes to come up with the best filling. I found Gluten Free on a Shoestring had a handy ratio in her recipe, so I followed that. Her basic ratio is 1/4 cup of milk for every egg. I used half and half instead.
What Vegetables/ Meat Do You Add?
I used sauteed mushrooms, onions and spinach for my vegetables. Really, you can use anything you like! I added the last remaining bits of turkey breast I had leftover from my Thanksgiving dinner to my egg mixture. I poured all of that deliciousness (and cheese!) into my prebaked mashed potato crust and waited with baited breath.
Best Gluten Free Quiche I’ve Ever Tasted
It was more beautiful than I even imagined! After allowing it to cool and set up, it sliced beautifully and held up well. It was even better the second day! In truth, this is delicious hot or cold. You’ll definitely want to add this recipe to your breakfast rotation! Thanks to Nicole Hunn and Jessica Webster for your insight on this dish!

I love this idea. I’ve got to try it with my own vegan filling. Thank you!
Can quiche be frozen? My husband doesn’t like it, but I miss it. I cant eat the whole thing, though.
This from Golden Valley (.com) would suggest the answer is yes.
“To freeze quiche after baking: Wrap with freezer paper or heavy-duty (or double thickness) aluminium foil or slide quiche into a freezer bag. Seal, label and freeze for up to one month.
Do not thaw before reheating. Remove wrap and bake in a preheated 350°F oven for about 25 minutes, or until heated through.”
You should be able to warm it in the microwave as well.
Can you freeze a mashed potato pie crust?
I’ve never tried that. I don’t think that would work well.
What a clever idea! I make quiches periodically but I don’t always want to mess with a crust.
Hey ! Can I make a crabmeat cheese egg brocolli quiche with this potato crust?
I’ve never tried that, so I can’t say. In theory, yes.
Hi. Am trying the potato base quiche . Is the base supposed to get crisp?
Thank you .
Dear Faye, I don’t know that I’d use the word “crisp,” but definitely firm and not mushy.
Could these be made into individual mini quiche for an event?
Not sure. Haven’t tried it. Theoretically yes?
