Ok, regular petits et grands choux (I just called you small and large cabbages…in French! I’m all about the culture) must acknowledge I love me some quiche. And while I completely dig a buttery, beautifully flaky crust, that crusts digs me, enough to permanently deposit itself on my thighs. So I’m all over the alternative crust bandwagon. The original recipe that inspired my version appears in the December 2018 Cooking Light magazine. 

One of the things that excited me most was the chance to use a hen of the woods mushroom that found its way into my kitchen. I think my daughter picked it up. This super-crazy mushroom occupies center stage on the cutting board.

Nuts, yes? But so delish. The aroma wafting through the air screamed classic, earthy mushroom goodness. (So often, store-bought mushrooms bring more texture than flavor to a meal.) You just cut all the little floaty things off the top, then dice the the bottom small. The recipe actually calls for 4 cups, so I added a package of store-bought mushrooms, chopped up. 

Sweet Potato Crust Quiche: How To

But I’m getting ahead of myself. First, slice the peeled sweet potato thin. I used 2 smallish-to-medium ones here. Line a pie plate with them, then bake at 400º.

Cook times, by the way, represent my biggest departure from the original. The original said to bake the slices for 15 minutes. Mine were nowhere near done, so I gave them another 15. THEN I could gently press them against the sides and bottom of the sprayed pie plate.

While the crust bakes, you sauté the mushrooms.

Also, mix eggs with milk (I used cashew) and grated mozzarella with thinly sliced chard. You could also gently sauté the chard leaves with the mushrooms. I like a lot of greens, more than the recipe called for, so I ended up with a green top rather than that nice yellow egg mixture to bind everything together. That said, I did like that the chard kept a little texture—not much, but I’m not big on mushy anything, and particularly greens. I also threw in some Parmesan not called for in the original, because I love cheese and think it makes a quiche more luscious.

 Now, you have all your layers. 

Add the sautéed mushrooms as the first layer. I’d added finely chopped chard stem to the sauté mix, btw; that’s what the little red things are. Also, be sure to salt and pepper everything.

The egg mix goes on top of that.

Then you bake it for about 20-35 minutes, til the eggs are set.

The finished product looks overly dark. Frankly, the pesto called for in the original, which I added, is a mistake. I thought it might be; pesto and sweet potatoes? Weird. But otherwise, this worked out to be a lovely brunch. Most interesting take-away here: the sweet potato crust. You can fill this with pretty much anything. In fact, I’ll experiment with a southern-inspired version later this week, and if it works, I’ll post. Meanwhile, enjoy this comfy, healthy, paleo/gluten-free/vegetarian take on quiche goodness.
