Mediterranean Quiche with Crispy Hash Brown Crust

Description

This Mediterranean Quiche with Crispy Hash Brown Crust combines a beautifully golden potato crust with a creamy egg filling loaded with spinach, juicy cherry tomatoes, tangy feta, Kalamata olives, red onion, and Mediterranean herbs. Instead of traditional pastry, shredded potatoes are pressed into the bottom and sides of the dish and baked until deeply golden and crispy. The savory egg filling is then poured inside and baked until tender and perfectly set. Every slice gives you creamy eggs, salty feta, colorful vegetables, and that irresistible crunchy potato edge. It’s an impressive recipe for breakfast, brunch, lunch, or a light dinner and pairs beautifully with a simple green salad.

Step-by-Step Instructions

1. Preheat the oven to 425°F (220°C) and lightly grease a 9-inch deep pie dish.
2. Place the shredded potatoes in a clean kitchen towel and squeeze firmly to remove as much moisture as possible. This is one of the most important steps for achieving a crispy crust.
3. Transfer the dried potatoes to a large bowl.
4. Add the beaten egg, olive oil, Parmesan, garlic powder, onion powder, oregano, salt, and black pepper.
5. Mix thoroughly until the potatoes are evenly coated.
6. Transfer the potato mixture to the prepared pie dish.
7. Firmly press the potatoes across the bottom and approximately 1½ inches up the sides, creating an even crust.
8. Bake for approximately 25–30 minutes, until the edges are deeply golden and the bottom begins to crisp.
9. Remove the crust from the oven and reduce the oven temperature to 375°F (190°C).
10. While the crust bakes, heat 1 tablespoon olive oil in a skillet over medium heat.
11. Add the red onion and cook for approximately 2–3 minutes until slightly softened.
12. Add the minced garlic and cook for another 30 seconds.
13. Add the spinach and cook just until wilted.
14. Remove the skillet from the heat and allow the vegetables to cool slightly.
15. In a large mixing bowl, whisk together the eggs, milk, and heavy cream until completely combined.
16. Add oregano, basil, optional red pepper flakes, salt, and black pepper.
17. Stir approximately ¾ cup feta into the egg mixture.
18. Spread the cooked spinach and onion mixture evenly across the hash brown crust.
19. Add most of the halved cherry tomatoes and sliced Kalamata olives.
20. Slowly pour the egg mixture over the vegetables.
21. Scatter the remaining tomatoes, olives, and feta across the top so the colorful ingredients remain visible.
22. Carefully return the quiche to the oven.
23. Bake at 375°F (190°C) for approximately 30–38 minutes, until the edges are set and the center has only a slight jiggle.
24. If the potato crust begins becoming too dark, loosely cover the edges with aluminum foil.
25. Remove the quiche from the oven and allow it to rest for 10–15 minutes before slicing.
26. Finish with fresh parsley, basil, additional feta, and freshly ground black pepper.
27. Slice into wedges and serve warm or at room temperature.

Tips

• Remove as much liquid from the shredded potatoes as possible. Excess moisture is the biggest enemy of a crispy hash brown crust.
• Russet potatoes work particularly well because their starch helps the crust hold together.
• Don’t skip pre-baking the potato crust before adding the filling.
• Sauté the spinach before adding it to prevent excess water from making the filling soggy.
• Use block feta and crumble it yourself for the best creamy texture.
• Don’t overbake the quiche. The center should be just set when it comes out of the oven and will continue cooking slightly as it rests.
• Allowing the quiche to rest before slicing helps create clean, beautiful wedges.
• For extra vegetables, roasted red peppers, artichoke hearts, zucchini, or mushrooms can be added.

Notes

This quiche can be served warm, at room temperature, or chilled. For meal prep, bake it completely, allow it to cool, and refrigerate promptly in an airtight container for up to 3–4 days. Individual slices can be gently reheated in the oven or air fryer, which also helps restore some crispness to the potato crust. Avoid overheating in the microwave if maintaining a crispy crust is important.

Q&A

Can I use frozen hash browns?
Yes. Thaw them completely first and squeeze out as much excess moisture as possible before preparing the crust.
Can I make this quiche ahead?
Yes. Bake it the day before, refrigerate, and gently reheat before serving.
Can I leave out the olives?
Absolutely. Replace them with roasted red peppers, artichokes, mushrooms, or simply add more tomatoes.
Can I make it without heavy cream?
Yes. Replace the cream with additional whole milk or half-and-half. The filling may be slightly less rich but will still work.
What should I serve with Mediterranean quiche?
A Greek salad, cucumber-tomato salad, roasted vegetables, fresh fruit, or a simple arugula salad with lemon dressing pairs beautifully.
