This loaded sweet potato crust quiche is exactly how I like my quiches, light on the eggs. I’m just not a huge fan, sorry. So I filled this one with lots of ham and veggies to make it really feel like a meal. It is still dairy, gluten, nightshade, and corn free. It’s a great recipe to use to test eggs in your elimination diet without introducing any other troublesome ingredients. It has the bonus of being super tasty, especially the way that sweet potatoes compliment smoky ham, that’s a match made in diet heaven!
The crust is the most challenging part of this brunch. You really want to get all the moisture out of the grated sweet potato that you can. Use a tea towel or a bunch of paper towels and really squeeze it all out. The last thing you want is a soggy crust. That is never appetizing. Additionally, do not underseason it. It may seem like a lot of salt, garlic and onion powder, but it’s really going to make the dish. Don’t be tempted to cut those out.
As far as ham goes you need to look for a natural brand that does not contain corn syrup. You don’t want ham to ruin your elimination diet with any sneaky ingredients. Whole foods always has great options but even my local Kroger had some at the deli. Ask for one thick slice and cube it yourself when you get home. You don’t need exactly ⅓ pound, that’s just a reference. Go ahead and snack on some extras if your quiche is looking too full.
What is a quiche?
Don’t get your egg dishes confused! Traditionally a quiche is made with a flaky pastry crust. This loaded sweet potato crust quiche uses sweet potatoes instead of flour and butter to make up the crust. But it’s still a quiche because it has any crust at all. A fritata is a crustless quiche and an omelette is a folded fritata. Or a fritata is an unfolded omelette. What egg came first? The fritata or the omelette?
