Ingredients

For the Potato Rosti Crust

• 1½ lb (680 g) Yukon Gold potatoes, peeled and coarsely grated
• 1 tbsp olive oil
• 1 tbsp butter, melted
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Zucchini & Leek Filling

• 1 medium zucchini, grated and squeezed very dry
• 1 medium leek, thinly sliced
• 1 tbsp olive oil
• 2 garlic cloves, minced
• 1/2 tsp dried thyme
• 1/4 tsp black pepper
• 1/4 tsp salt

For the Quiche Filling

• 5 large eggs
• 1/2 cup (120 ml) milk or heavy cream
• 1 cup (100 g) crumbled feta cheese
• 1/2 cup (50 g) shredded mozzarella cheese
• 1/4 cup (25 g) grated Parmesan cheese
• Pinch of nutmeg, optional

How to Make Golden Potato Rosti Crust Quiche

1. Prepare the Potatoes

Preheat the oven to 425°F (220°C).

Place the grated potatoes in a clean kitchen towel and squeeze firmly to remove as much moisture as possible. Removing excess moisture helps the potato crust become golden and crisp.

Transfer the potatoes to a bowl and mix with the olive oil, melted butter, salt and black pepper.

2. Form the Rosti Crust

Lightly grease a 9-inch (23 cm) pie dish.

Press the grated potato mixture firmly into the bottom of the dish and slightly up the sides, creating an even crust.

3. Bake the Potato Crust

Bake for 25–30 minutes, until the potatoes are golden and beginning to crisp around the edges.

4. Cook the Zucchini and Leek

While the potato crust bakes, heat the olive oil in a skillet over medium heat.

Add the sliced leek and cook for 4–5 minutes, until softened.

Add the grated zucchini and minced garlic. Cook for another 3–4 minutes, until most of the moisture has evaporated.

Season with dried thyme, salt and black pepper.

5. Prepare the Egg and Cheese Mixture

In a large bowl, whisk together the eggs and milk or heavy cream.

Stir in the crumbled feta, shredded mozzarella, grated Parmesan and nutmeg if using.

6. Assemble the Quiche

Remove the pre-baked potato crust from the oven.

Spread the cooked zucchini and leek mixture evenly over the potato crust.

Pour the egg and cheese mixture over the vegetables, making sure it is distributed evenly.

7. Bake Until Set

Reduce the oven temperature to 375°F (190°C).

Bake the quiche for 30–35 minutes, until the centre is set and the top is golden.

8. Rest Before Slicing

Allow the quiche to rest for 10–15 minutes before slicing.

This gives the filling time to firm up while helping the potato crust retain its crisp texture.

Tips for the Best Potato Crust Quiche

• Squeeze the potatoes well: Excess moisture can prevent the rosti crust from becoming properly golden.
• Press the crust firmly: A compact, even layer helps the potato crust hold together.
• Cook the zucchini until dry: Removing excess moisture from the zucchini helps prevent a watery filling.
• Don’t skip the pre-bake: Baking the potato crust before adding the filling helps it develop a golden texture.
• Allow the quiche to rest: The short resting period makes the quiche easier to slice cleanly.

How to Serve Potato Rosti Crust Quiche

Serve slices of the quiche warm after the 10–15 minute resting period. The golden potato crust pairs beautifully with the creamy feta, tender zucchini and savoury leek filling.

It works well as a main dish for breakfast, brunch or lunch, or as part of a larger meal with a fresh salad or vegetables.

Frequently Asked Questions

Can I use another type of potato?

The recipe specifically calls for Yukon Gold potatoes, which are peeled and coarsely grated to create the rosti crust.

Why do I need to squeeze the grated potatoes?

Removing as much moisture as possible helps the grated potatoes bake into a golden, crisp crust rather than staying overly wet.

Can I use milk instead of heavy cream?

Yes. The recipe allows either milk or heavy cream for the egg mixture.

How long should the quiche rest before slicing?

Allow it to rest for 10–15 minutes. This helps the filling firm up while keeping the potato crust crisp.

Can I prepare this quiche for brunch?

Yes. The combination of the golden potato crust, vegetables and cheese makes it well suited to breakfast, brunch or lunch.
