Celebrate spring with a light, delicious asparagus quiche baked in a gluten-free sweet potato crust. This simple recipe uses just seven main ingredients and is ideal for brunch, Easter, or any spring gathering.
Asparagus is one of the first vegetables of spring and pairs beautifully with eggs, cheese and fresh herbs. Here it stars in a quiche with a naturally gluten-free crust made from thinly sliced sweet potatoes. The result is tender, flavorful and visually striking.
Asparagus Quiche Ingredients
This recipe focuses on a few fresh, easy-to-find ingredients:
- sweet potatoes;
- eggs;
- quark (or a suggested substitute);
- Dijon mustard;
- Gruyère cheese (or similar);
- thyme;
- asparagus.
A couple of spoonfuls of Dijon mustard lifts the whole dish and complements the natural sweetness of asparagus. If you need ingredient swaps, see the recipe notes and variations below.
How To Make This Quiche
Make the sweet potato crust
Preheat the oven and lightly grease a pie pan. Peel and very thinly slice the sweet potatoes (a sharp knife or mandoline works well). Line the bottom and sides of the pan with overlapping slices in two layers so the pan is completely covered — sweet potatoes shrink while baking. Season with salt and pepper and bake about 15 minutes until slightly tender.
Make the quiche filling
Whisk the eggs until foamy, then stir in quark, Dijon mustard, grated Gruyère, thyme and salt and pepper to taste. When the crust is ready, arrange half the asparagus spears over the bottom. Pour the egg mixture over the asparagus and spread evenly. Lay the remaining asparagus on top and gently press so some spears are partially embedded.
Bake
Bake at a moderate temperature for about 35–40 minutes, until the filling is set and the top has light color. Allow the quiche to rest a few minutes before slicing and serving.

Why This Recipe Works
- Just seven main ingredients, easy to find at most stores.
- Asparagus, eggs, Gruyère and mustard form a classic, well-balanced combination ideal for brunch.
- Quark keeps the filling lighter than heavy cream while still providing a creamy texture.
- The filling reliably sets in about 35 minutes, so you won’t have a runny center.
Cook’s Tips
- Use a few extra sweet potato slices to ensure full coverage of the pan — they do shrink when baked.
- Choose fresh asparagus for the best flavor and texture.
- If your sweet potatoes are narrow, slice them lengthwise to cover the pan more easily.
- Arrange asparagus in any pattern you like or trim and stack spears for even coverage.
- Blanching asparagus is optional; it won’t hurt but isn’t necessary for this bake.
- Store leftovers in the fridge up to 4 days. Reheat in the oven or microwave.
Recipe Variations
- Swap the sweet potato crust for a traditional whole-grain crust if you prefer.
- Replace quark with ricotta, cream cheese or crème fraîche for a different texture.
- If Gruyère isn’t available, substitute Emmental, Appenzeller, Gouda or another firm melting cheese.
- Use cooking spray instead of olive oil to grease the pan.
- Use 1 teaspoon dried thyme if you don’t have fresh, or experiment with other herbs you enjoy.
What Goes With Asparagus Quiche?
This quiche is substantial enough to stand on its own, but it pairs nicely with a light spring salad. Try a simple mixed greens salad, or a salad featuring seasonal ingredients like radishes, strawberries or shaved asparagus.
For a more elaborate brunch, serve the quiche alongside fruit, baked pears with cheese, sweet potato rolls or a light soup.
