Asparagus Quiche with Sweet Potato Crust {GF/Low Carb/Keto}

A delicious and ridiculously easy Asparagus Quiche recipe made the low carb way with a healthy sweet potato crust.  Filled with roasted asparagus and two different kinds of cheese, this quiche is an ideal meal for any time of the day!

Quiche is one of my favorite recipes to make because I love it's versatility.

It can be served hot, cold, or at room temperature for breakfast, brunch, lunch, or dinner.

Quiches can also be a starter to a formal meal or as an entree to a lighter one.

This asparagus quiche is a quick and easy, healthy vegetarian recipe that is gluten free, low carb and keto friendly too.

Quiche ingredients can be carefully planned ahead or just use whatever is in the refrigerator (it's an awesome clean-out-the-fridge recipe).

Typically I make a quiche when I haven't gone grocery shopping and/or I have no idea what to make for dinner.

Thankfully, I always have eggs, some kind of veggie, and several different types of cheese on hand.

All the makings of a perfect quiche right in my refrigerator at all times!

When is Asparagus Season

Asparagus is available year-round, but Spring time is the ideal season for this tender vegetable. 

Here in New England, we had a late start to our growing season this year, so all our local farms had fresh asparagus stalks up to late July. 

Normally, crops are harvested from late February to June, with April being the peak month and when prices will be the most reasonable. 

The Perfect Crust for a Low Carb Quiche

I originally saw this asparagus quiche recipe on the vegetarian/vegan site Happy Kitchen.Rocks and was inspired by their use of a sweet potato pie crust. 

The idea of using nutritious sweet potatoes slices as a gluten free quiche crust completely fascinated me and I became determined to make my own version. 

All the ingredients I used are everyday ones, easily found in stores or in one's own refrigerator. 

Using only a single layer of asparagus, I roasted it to bring out it's full flavor before adding it to the quiche.

I also omitted the quark, gruyère, fresh thyme, and mustard in the original recipe. Instead adding feta and cottage cheeses with heavy cream to my version. 

A high quality feta is an ideal cheese in this recipe, as it will add a salty boost to the cottage cheese and creamy texture to the cooked eggs.

The saltiness of the feta is an outstanding complement to the delicate taste of the sweet potato crust too.

How to Make an Easy Sweet Potato Crusted Asparagus Quiche

• Use a mandolin to thinly slice the sweet potato.
• Lightly grease a 12 inch pie pan with oil. Layer the potato slices in the pan, overlapping them because they will shrink during cooking. Sprinkle them lightly with salt and pepper. Bake at 370F degrees for 15 minutes.
• Roast the asparagus spears at 425F degrees for 5 minutes. Set aside.
• Make the simple quiche filling by mixing together eggs, cottage and feta cheeses, heavy cream, salt and pepper.
• Pour the filling into the sweet potato prepared pie pan. Bake the quiche at 370F degrees for 30 minutes, or until the filling is set.
• Serve and eat the quiche immediately or at room temperature. Store the leftovers, covered, in the refrigerator for up to 4 days.

Can I Freeze Leftover Quiche? 

Absolutely!  Obviously, it won't be as good as when it's fresh and the consistency may change slightly, but it's better than wasting any leftover quiche.  I successfully froze individual slices of this egg pie for later use and here's how I did it:

1. I wrapped each slice in freezer paper and labeled them.  Each slice can also be wrapped in plastic wrap or foil. Put the slices in a plastic freezer bag and label.
2. Freeze up to 1 month, for best results (but can freeze up to 2 months).
3. When ready to use:  Don't worry about thawing before reheating.  Just unwrap the slices and place on a baking sheet. Bake for 10-12 minutes in a preheated 350F degree oven, until heated through.
4. If you don't want to freeze the quiche, it will stay fresh for 3-4 days, covered and in the refrigerator.
