Ingredients
For the Potato Rosti Crust
- 2 large russet potatoes, peeled and grated
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 tablespoons olive oil
- 2 tablespoons butter
For the Caramelized Onion & Leek Filling
- 1 large yellow onion, thinly sliced
- 2 medium leeks, white and light green parts thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- Salt and black pepper, to taste
For the Quiche Filling
- 5 large eggs
- ¾ cup heavy cream or whole milk
- ½ cup crumbled goat cheese
- ¼ cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped
- ½ teaspoon paprika (optional)
Instructions
Step 1: Prepare the Potato Rosti Crust
Preheat your oven to 400°F (200°C). Place the grated potatoes in a clean kitchen towel and squeeze out as much moisture as possible. Removing excess water helps create a crispy golden crust. Mix the grated potatoes with salt and black pepper.
Heat olive oil and butter in a skillet over medium heat. Add the grated potatoes and press them evenly across the bottom and slightly up the sides of a pie dish or oven-safe skillet to form a crust. Cook for 5–7 minutes until the bottom begins to turn golden. Transfer the crust to the oven and bake for 20 minutes until crispy and lightly browned.
Step 2: Make the Caramelized Onion and Leek Filling
While the potato crust bakes, heat butter and olive oil in a large pan over medium-low heat. Add sliced onions and cook slowly for 15–20 minutes, stirring occasionally, until they become soft, golden, and caramelized.
Add the sliced leeks and garlic, then continue cooking for another 8–10 minutes until the leeks are tender and fragrant. Season with thyme, salt, and black pepper. Remove from heat and allow the mixture to cool slightly.
Step 3: Prepare the Quiche Mixture
In a large bowl, whisk together eggs and heavy cream until smooth. Add Parmesan cheese, half of the goat cheese, parsley, paprika, and a pinch of salt and pepper. Stir gently to combine.
Spread the caramelized onion and leek mixture evenly over the baked potato crust. Pour the egg mixture over the top and sprinkle the remaining goat cheese across the surface.
Step 4: Bake the Quiche
Reduce oven temperature to 375°F (190°C). Bake for 30–40 minutes, or until the center is fully set and the top is beautifully golden. The quiche should have a slightly firm texture with a creamy interior.
Allow it to rest for 10 minutes before slicing. Garnish with extra fresh parsley or thyme before serving.
Tips & Notes
- Squeeze the potatoes very well before making the crust to achieve the crispiest rosti texture.
- Slow caramelization creates the best flavor, so avoid cooking onions too quickly on high heat.
- You can prepare the potato crust and filling ahead of time and bake when ready.
- For extra flavor, add sautéed mushrooms, spinach, or roasted red peppers.
- Goat cheese can be replaced with feta cheese or cream cheese for a different taste.
- This quiche tastes delicious warm, at room temperature, or even chilled.
