I’m pretty excited about this recipe. I’ve always loved a good spinach quiche at coffee places but just never got around to actually trying my hand at one. So today we’ll be trying a breakfast version, combining delicious hash brown shreds to make the crust in lieu of a traditional pie crust.

It’s like a bigger, quiche version of hash brown egg nests!

It’s good hot or cold and you can even make it the day before. Because no one is gonna muck about the kitchen for an hour in the morning for breakfast. At least I won’t. So this is good for breakfast made ahead of time, or good for a brunch and serves a pretty good amount of people.

And onto the cooking!

Grease the pan before packing it tightly with the hash brown mixture. You’ll want the hash brown to resemble a pie crust so pack it on the bottoms and the sides with your fingers. It’s also handy to use the back of a spoon pressed along the edges to lift up the sides a little more.

Not much oil is needed to saute the zucchini and mushrooms. Don’t worry if the mushrooms look like they’re too bulky to fit in the quiche, it’ll cook down and release some liquid. Once the veggies are cooked down, drain off excess liquid. You’ll want the veggies nice and dry so they don’t dilute the custard. You should end up with about two cups of veggies once they’re cooked down.

Once the hash brown crust is all browned, spread a layer of cheddar cheese along the bottom and top with the veggies and bacon bits making sure to spread them all out evenly. Then top it again with more cheese for a really rich quiche. I went with one and half cups of cheese and divided it into two for the bottom and top. For a richer quiche, use two cups of cheese or use one cup for a lighter version.

Then you make the custard by combining the eggs and milk with salt and pepper to taste. Whisk, whisk whisk until it’s frothy! A good rule of thumb for a nice quiche is to have two eggs to one cup of milk. I used large eggs for this recipe. Pour the custard over the fillings and you’re ready to bake!

Baking will take some time to allow the eggs to set. Bake it until a butter knife inserted in the middle comes out clean. Let it cool down before slicing. It’ll need time to set.

The good news is this breakfast quiche is really versatile. You change your fillings as you like or with whatever you have leftover in the fridge. Other ideas would be to use bell peppers, leeks or spinach. Just make sure the fillings are dry and amount to about two cups to not overcrowd the custard filling.

And that’s it! Happy brunching!

    We loved it! I used O’Brien potatoes and less olive oil, the cubed ham from our Christmas dinner. Deeeelish! Thanks for the recipe.

    hi there! Do you need a cast iron skillet to make the hash browns crispy? I’m worried that I only have a pyrex tray and the has browns won’t get as crispy as pictured.

    Are there any pre-steps I can take on the stovetop beforehand to get it crispy before going into the oven?

    Thanks!

      I’m honestly not entirely sure about just how much impact a cast iron vs normal casserole would have on the crispness of the hash browns, if any. But my gut says the blind baking prior to putting in the filling should be enough for it to work with what you have. Good luck, SC!

    Made this today, Christmas Day, for a brunch. Followed recipe exactly, except left out bacon, for vegetarian family members. Turned out okay, not great. Hash brown crust was dry & too crunchy. Did not overcook it in beginning. Cooked in oven after adding egg mixture for 42 min. Was done. Will not make again.

      I’m sorry you didn’t like it, Karen! I actually loved the crunchy bits of the crust but not everyone is the same. Thank you for trying it out anyway.

    hi…
    Making this tomorrow morning, but as i was reading over the recipe, you don’t say how much EVOO to add to the hash browns. I am assuming it is 1 Tbsp (?) Also, you do not say “thawed” after the “frozen hash browns, but in a review, you told someone that they should be thawed. Now I’m trying to figure out what time to get up tomorrow to thaw the hash browns. Please make this more clear in your recipe. Thank you.

      Great suggestions, Karen. I’ve gone ahead and added these to the recipe to make it clearer. Thank you!

    Looks very yummy. Is it necessary to pre-cook the “crust”? Would the hash browns cook and brown anyway as it cooks for 45-50 minutes?

      Heya Carrie! Cooking the crust before adding in the filling is called blind-baking. It’s done so the bottom of the crust doesn’t become soggy from moisture of the filling if they are baked together!
