Pumpkin Sweet Potato Quiche with Roasted Garlic is the kind of recipe that never fails. It is simple to prepare, always works, and delivers a rich, warm flavor that fits perfectly with autumn. With roasted vegetables, a creamy filling, and a crisp homemade crust, this quiche is a dish you will be glad to put on the table. Serve it for lunch, dinner, or bring it to a gathering-it looks impressive and tastes even better.

Pumpkin Sweet Potato Quiche with Walnuts
This quiche is one of my favorite autumn recipes, because it brings together everything I love about this season: pumpkin, sweet potatoes, nuts, and the deep flavor of roasted garlic. I first baked it for a family lunch, and since then, it has become a regular in my kitchen.
The crust is easy to prepare, the filling is soft and full of flavor, and the vegetables roasted with herbs make it special. I often serve it warm with a simple green salad or a bowl of soup.
And the best part-it is tested more than once, so I know it works every time. When I make this recipe, I know there will be smiles at the table, and usually no leftovers.
This recipe has been adapted from a recipe from the book Small savory tarts - Petit Gâteau.
What do you need for Pumpkin Quiche in Autumn?
To prepare this fall quiche with pumpkin, you require the following ingredients. You can find the correct amounts in the recipe card at the bottom of the blog:

- Flour: You can use regular wheat flour for this recipe.
- Sugar and salt: Balances the flavor.
- Butter: Unsalted butter, as cold as possible. Cut the butter into flakes when making the dough, so it melts during baking and forms delicious creamy parcels.
- Milk: For making the dough creamy and smooth. Milk is also used for the filling, so it tastes creamy.
- Egg: An egg yolk is used in the dough to make it creamier and fuller in flavor. You use a whole egg and a yolk for the quiche cream filling. This ensures binding and a richer taste.
- Cream: Contains more fat than milk, which gives the filling that velvet taste.
- Nutmeg: A spice with a deep, bittersweet taste. Grate fresh nutmeg that tastes the best. Instead of a dash of nutmeg, add a dash of pumpkin spice.
- Pumpkin and Sweet Potato: You use these typical winter vegetables as a filling in this quiche. Roasting the pumpkin, sweet potato, and garlic before using them as a filling will give them even more flavor. Replace the sweet potato or pumpkin with carrots. Such a delicious autumn vegetable.
- Garlic: Gives the filling more flavor.
- Walnuts and Hazelnuts: Roughly chopped, they give a bite and a nutty flavor to the quiche. Instead of walnuts, you can also replace them with the same amount of sweet chestnuts.
- Thyme: A seasoning that's extra tasty when you're roasting something (like the roasted sweet potato and pumpkin here).
- Cinnamon: A sweet, woody flavor that brings out the flavors of the vegetables.
How to prepare this Easy Fall Pumpkin Quiche
You can find a printable recipe with a step-by-step description at the bottom of this blog.

- Mix flour, sugar, and salt and put in the food processor. Add the cold butter and pulse until pea-sized. Pour the cold milk and egg yolk into the flour mixture and pulse until the dough loosens from the sides. Remove from the bowl and wrap in plastic wrap. Let it cool for at least 30 minutes in the refrigerator. Then cover the mold with the dough and let it cool for 30 minutes.
- Mix the ingredients for the filling. Let it cool for at least 30 minutes.
- Bake the pumpkin, sweet potato, and garlic in a preheated oven at 350°F (180°C), seasoned with cinnamon, nutmeg, olive oil, salt, and pepper. Then add the nuts and thyme.
- Fill the quiche with the roasted vegetable mixture and the cream filling. Bake in the oven for 20 minutes, then cover with aluminum foil and bake for another 20 minutes. Remove the form and serve immediately.
Ingredients left?
Of course, it can always happen that you still have leftovers or something remains. Below are tips for handling them.
- If you have any leftover quiche, warm it up the next day (or eat it cold). Maybe the flavors are even better.
- You use the egg yolk, but not the white. You can make a delicious pavlova, macarons or a sour sherry cocktail with the egg whites.
- Some pumpkin left? Make a delicious pumpkin soup with saffron, pumpkin curry, or pumpkin cheesecake.
- Sweet potato can also be used for these delicious vegetarian tacos with sweet potato and beans, a sweet potato hummus or in this chicken and sweet potato in coconut sauce stew.
