Ingredients for the Sweet Potato Crust

Here are some of the ingredients that make this quiche such a delicious gluten free option!

  • Sweet potatoes: When peeled, grated, and combined with egg and some seasoning, sweet potatoes make the perfect quiche crust!
  • Egg: Large eggs act as a binder for the sweet potato crust.
  • Red pepper flakes: Red pepper flakes give a little kick and extra flavor to the crust.
  • Salt and pepper: Kosher salt and pepper are essential spices that make the crust flavor really stand out.

How to Make Sweet Potato Crust

  • Grease the inside of a springform pan with nonstick spray or olive oil spray. Line the inside with parchment paper, then grease again with more cooking spray.
  • Peel the sweet potatoes and grate with a large-holed box grater. Then, squeeze out any moisture with cheesecloth, a paper towel, or a clean kitchen towel.
  • Whisk together the egg and seasoning in a medium bowl, then add in the grated sweet potato. Stir until everything is well incorporated.
  • Next, press the sweet potato mixture along the inside of the springform pan. Place the pan on a cookie sheet and bake until crispy and set, then cool before adding the filling.

Tip: Be sure to squeeze any excess moisture out of the grated sweet potato before mixing it with the other crust ingredients.

Ingredients for the Filling

These bold ingredients make for a flavorful, delicious quiche!

  • Leek: Be sure to thoroughly wash and thinly slice your leeks for the best results.
  • Butter: Every quiche is made better with rich and creamy butter!
  • Coconut milk: I like to use full-fat coconut milk from a can as an alternative to heavy cream. But you can choose to use heavy cream, if you’d prefer.
  • Goat cheese: Get fresh goat cheese or pre-crumbled goat cheese to add creamy tang to your sweet potato crusted quiche.
  • Eggs: Of course, no quiche is complete without eggs, the main event!
  • Salt and pepper: Salt and black pepper add simple spice to the dish that lets the main ingredients of this sweet potato crust quiche shine.

Make the Filling

  • Melt the butter in a pan over medium-high heat. Cook the leeks in the butter until softened, seasoning with salt and pepper. Then, remove from heat and let cool.
  • Next, whisk together the eggs, coconut milk, salt, and pepper until smooth. Stir in the cooled leeks and half of the goat cheese until just combined.
  • Pour egg mixture into the sweet potato crust and top with the rest of the goat cheese.
  • Bake the goat cheese and leek quiche until the center is mostly set, about 30 minutes. Then, let it cool to room temperature before serving.

How to Clean and Cut Leeks 

The process is similar to slicing green onions, but with a little more cleaning involved.

  • Cut off the root and the dark green tops. Discard both (or save the tops to use for soup or stock).
  • Slice the remaining white and pale green stalks into thin rings.
  • Place the sliced leeks into a bowl of water and swish them around to remove the dirt and grime.
  • Then, scoop out the leeks with your hands or a slotted spoon and pat dry.

Sweet Potato Crusted Quiche (with Goat Cheese and Leeks!)

Prep Time 30 mins
Cook Time 1 hr
Total Time 1 hr 30 mins
Servings 6 -8 servings
Sweet Potato Crusted Quiche with Goat Cheese and Leeks! {Gluten-Free} This quiche is a crowd-pleaser! Serve it at your next holiday brunch.

Ingredients

For the Crust:

  • 2 large sweet potatoes about 2lbs, peeled and grated on a large-holed box grater
  • 1 1/2 teaspoons salt
  • 1 teaspoon pepper
  • pinch crushed red pepper flakes
  • 1 egg

For the Filling:

  • 1 leek white and green parts washed and thinly sliced
  • 2 tablespoons butter
  • 8 eggs
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/4 cup full-fat coconut milk or heavy cream
  • 3 ounces goat cheese crumbed

Instructions 

  • Preheat oven to 450 degrees F.
  • Grease the bottom and side of a 9-inch springform pan with cooking spray. Cut parchment paper in a circle the diameter of the bottom and another to fit the sides of the pan (one circle and one long rectangle). Line the pan with the parchment, then spray the parchment with more cooking spray. You can also just use a standard 9-inch pie pan and serve it right out of the pan (so you can skip the parchment step). The springform pan just makes a more dramatic presentation.
  • Place the grated sweet potatoes in a large piece of cheesecloth or a clean kitchen towel. Gather corners together and squeeze out any moisture.
  • In a medium bowl, whisk together 1 egg, 2 teaspoons salt, 1 teaspoon black pepper & a pinch of crushed red pepper flakes. Add the squeezed sweet potatoes and mix to totally combine. Press the sweet potato mixture into the bottom and up the sides of the prepared pan. Place on a rimmed cookie sheet and bake for 30 minutes. Remove from oven and allow to cool slightly, about 10 minutes.
  • Turn oven down to 350 degrees F.
  • Meanwhile, heat the butter over medium high heat. Add the leeks, along with a pinch of salt and pepper and cook until softened, about 6-8 minutes. Let cool slightly before adding to the egg mixture.
  • For the egg mixture, whisk together the eggs, salt, pepper, and coconut milk or cream until totally smooth. Add the cooled leeks and 1/2 the goat cheese. Stir to combine. Pour the filling into the prepared crust. Sprinkle the rest of the goat cheese on top.
  • Bake 30 minutes, until the center is mostly set. Allow to rest 20 minutes before serving. Serve at room temperature. Enjoy!

    Hi Erin,

    I make this recipe ALL the time, and it’s DELICIOUS.
    I want to try to cook more with local and in season ingredients, so I was wondering, any chance one could substitute shredded butternut squash in the crust?

    Thanks 🙂
