2. Step-by-step instructions
Step 1: Prepare the potatoes
Preheat your oven to 200°C (400°F). Peel the potatoes and grate them using the large holes of a box grater.
Place the grated potatoes in a clean kitchen towel and squeeze firmly to remove as much moisture as possible. This is essential for a crisp crust rather than a soggy one.
Step 2: Shape the potato crust
Mix the grated potatoes with olive oil, salt, pepper, and optional garlic powder. Press them firmly into the bottom and up the sides of a greased 9-inch (23 cm) springform or deep pie pan.
Make the base evenly thick and press the potatoes firmly into the corners so the crust holds together after baking.
Step 3: Pre-bake the crust
Bake the potato crust for 25–30 minutes, until the edges begin to turn golden. For extra crispness, lightly brush the surface with a little additional oil and bake for another 5 minutes if needed.
Remove it from the oven and set aside. Keep the oven at 200°C (400°F).
Step 4: Cook the vegetables
Heat 1 tablespoon olive oil in a skillet over medium heat. Add the onion and cook for 3–4 minutes until softened. Add the garlic and cook for 30 seconds.
Add the spinach and stir until wilted, approximately 2–3 minutes. Remove the skillet from the heat and squeeze or drain off excess liquid. Stir in the chopped sun-dried tomatoes and oregano.
Step 5: Make the egg filling
Whisk the eggs, milk, cream, thyme, and black pepper in a large bowl. Fold in the spinach mixture and about three-quarters of the crumbled feta.
Taste the vegetable mixture before adding any extra salt. Feta and sun-dried tomatoes can both be quite salty.
Step 6: Fill the crust
Pour the egg mixture into the pre-baked potato crust. Spread the spinach and tomatoes evenly, then sprinkle the remaining feta and sun-dried tomatoes over the top.
If the filling comes close to the rim, leave a little space to prevent spilling as it cooks.
Step 7: Bake the quiche
Bake for 25–35 minutes, or until the center is set and no longer liquid. The top should be golden, and a knife inserted near the center should come out without wet egg mixture.
If the potato edges brown too quickly, cover them loosely with foil. For food safety, the egg filling should reach 71°C (160°F).
Step 8: Rest, slice and serve
Allow the quiche to rest for 10–15 minutes before removing the springform ring and cutting into slices. This helps the filling set and keeps the potato crust intact.
Finish with fresh chives, basil, and black pepper. Serve warm or at room temperature.
3. Secrets to a crispy potato crust
- Remove excess moisture: Wet grated potatoes are the biggest reason for a soft crust.
- Pre-bake before adding eggs: This gives the potatoes a head start and prevents a soggy base.
- Use enough oil: A thin coating encourages browning and helps the potato strands crisp.
- Drain the spinach: Cooked spinach releases water, which can interfere with the egg filling setting.
- Allow the quiche to rest: Cutting too early can make the filling fall apart.
- Use a removable-bottom pan: A springform pan makes it easier to present the quiche with its tall, golden sides.
4. All nut information and allergy guide
Naturally nut-free ingredients
The standard recipe does not require peanuts or tree nuts. Potatoes, eggs, spinach, feta, milk, garlic, onion, and herbs are not nuts.
Optional nuts
Chopped walnuts, almonds, or pine nuts can be added for crunch, but they are not traditional or necessary. Pine nuts are botanically seeds but are commonly included in food-allergy precautions for tree nuts.
For strict nut allergies
Omit all nuts and nut-based toppings. Check labels on cheese, sun-dried tomatoes, oils, and seasonings, and prevent cross-contact with shared utensils, pans, and preparation surfaces. Use a fresh bottle of olive oil rather than an oil that may have been contaminated.
Other allergens to know about:
- Dairy: Feta, milk, cream, and butter contain dairy unless replaced with suitable alternatives.
- Eggs: The filling relies on eggs to set.
- Gluten: The recipe is naturally gluten-free if all packaged ingredients are suitable and free from cross-contact.
- Sulfites: Some packaged sun-dried tomatoes contain added sulfites. Check the label if sulfite sensitivity is a concern.
5. Nutrition information
Approximate nutrition per serving, based on six servings using the ingredients above and no optional nuts:
| Nutrient | Estimated amount |
|---|---|
| Calories | 330–400 kcal |
| Protein | 13–17 g |
| Carbohydrates | 30–38 g |
| Fat | 17–23 g |
| Fiber | 3–5 g |
| Sugar | 4–8 g |
| Sodium | 450–700 mg |
These values are estimates and can vary significantly with the potatoes, cheese, cream, and type of sun-dried tomatoes used. For a lower-calorie version, use milk instead of cream, reduce the olive oil slightly, and use a little less feta.
6. Delicious variations
Extra-cheesy version
Add ½ cup shredded mozzarella to the egg mixture for a softer, stretchier filling.
Greek-inspired version
Add ¼ cup sliced Kalamata olives and a little lemon zest. Reduce added salt to balance the olives and feta.
Higher-protein version
Replace some cream with additional egg whites and use a protein-rich cottage cheese alongside the feta. The texture will be slightly different, but the protein content will increase.
Dairy-free adaptation
Use suitable dairy-free feta and milk alternatives. Because eggs provide the structure, a fully vegan version also needs an appropriate egg replacement designed for savory quiches.
7. Frequently asked questions (Q&A)
Q1. Can I make this quiche without a springform pan?
Yes. A deep 9-inch pie dish or oven-safe cake pan works. Grease it thoroughly and allow the quiche to rest before slicing. A springform pan is particularly useful for showing off the tall potato crust.
Q2. Why is my potato crust soggy?
The potatoes may not have been squeezed dry, the crust may not have been pre-baked long enough, or the spinach may have released too much water. Dry the potatoes thoroughly, pre-bake until lightly golden, and drain the cooked spinach.
Q3. Can I use frozen spinach?
Yes. Use approximately 150 g thawed frozen spinach, then squeeze it very dry before adding it to the skillet. Frozen spinach often holds more water than fresh spinach.
Q4. Can I prepare it the night before?
Yes. Bake the quiche, cool it promptly, and refrigerate it covered. Reheat slices in the oven at 175°C (350°F) until hot. The crust will generally be crispier when reheated in an oven than in a microwave.
Q5. Can I freeze the quiche?
Yes. Cool completely, cut into portions, wrap well, and freeze for up to about two months for best quality. Thaw in the refrigerator and reheat thoroughly. The potato crust may lose some crispness.
Q6. Can I use sweet potatoes for the crust?
Yes. Sweet potatoes offer a slightly sweeter flavor and can work as a grated crust. They soften differently from regular potatoes, so squeeze out moisture and pre-bake until the edges begin to brown.
Q7. What can I use instead of feta?
Goat cheese provides a tangy, creamy alternative. Ricotta gives a milder flavor, while grated Parmesan adds a salty, savory finish. Adjust salt according to the replacement cheese.
Q8. Are sun-dried tomatoes packed in oil suitable?
Absolutely. Drain them well and blot away excess oil before chopping. You can use a small amount of their flavored oil for sautéing the onion, provided it is suitable for your dietary needs.
Q9. How do I know when the quiche is done?
The center should look set rather than liquid, and the filling should reach 71°C (160°F). A slight wobble is fine, but a visibly wet center needs more baking time.
Q10. Is this recipe gluten-free?
The ingredients in the basic recipe are naturally gluten-free. Check labels on packaged ingredients and avoid cross-contact if preparing food for someone with celiac disease.
Q11. Is this quiche vegetarian?
Yes, provided the feta and other cheeses are made with vegetarian-friendly rennet. Check the cheese label if you avoid animal-derived rennet.
Q12. How do I make it lower in carbohydrates?
The potato crust contributes most of the carbohydrates. You could use a thinner potato layer and increase the spinach and egg filling, or try a crust made from lower-carbohydrate vegetables. The nutrition will change accordingly.
Q13. What should I serve alongside it?
Try a crisp cucumber and tomato salad, roasted vegetables, a light green salad with lemon dressing, or a bowl of tomato soup. It also works beautifully with fresh fruit for brunch.
Q14. How long do leftovers last?
Refrigerate within two hours of cooking and store at 4°C (40°F) or below. Consume within 3–4 days and reheat until steaming hot throughout.
8. Serving and presentation
For a presentation similar to your picture, remove the quiche carefully from the pan and place it on a white serving platter. Scatter chopped chives across the golden top, arrange the sun-dried tomatoes prominently in the center, and add a few extra crumbles of feta.
Serve each slice with a fresh Mediterranean salad or roasted vegetables.
Final result: A crisp, golden potato crust surrounding a creamy, savory spinach and feta filling, finished with sweet-tangy sun-dried tomatoes and fresh herbs. Perfect for brunch, entertaining, or an easy vegetarian meal. 🥔🍅🧀
