I have a slightly unhealthy obsession with Sweet Potatoes. And I honestly have no idea where this deep-seated love for sweet potatoes comes from or how to explain it. Especially since I used to hate them.
Every Thanksgiving I’ve ever attended has had some form of sweet potato casserole and until recently I used to avoid this dish. Now it’s one of my favorite things to eat during Thanksgiving. But wait a minute, Thanksgiving is over and I’m still obsessed and not satiated. I need more sweet potatoes!
Luckily, the place I work always has grilled sweet potato slices on hand. Suffice to say, these perfectly grilled sweet potato slices aren’t safe from my greedy hands. Which is probably why the cooks I work with have started hiding them from me (Yes. This is highly unfair and a huge injustice). So I’ve had to resort to making them in my own home so that I get my requisite weekly amount.
This quiche is a perfect way for me, or anyone, to get their sweet potato fix. It is layered with bacon (another one of my food obsessions), and caramelized onions (another item I used to hate and can’t get enough of now), with Gruyere. The great thing about quiches is that they’re good both warm and cold. Which is great when you’re too hungry and too lazy to warm your slice up.

I’m going to level with you. Joy the Baker knows what she’s talking about when it comes to pie dough. The woman has never led me astray and she won’t lead you astray either. Which is why I used her Pie Crust recipe. Just switch out the all purpose flour for whole wheat.
Or just buy a pre-made pastry crust.
