Greek-Style Zucchini Phyllo Quiche

Here’s my take on a zucchini phyllo quiche recipe that combines crispy, paper-thin layers of phyllo with a creamy egg filling and fresh zucchini from the garden. I love how the pastry gets golden and flaky while the inside stays soft and smooth.

This quiche has become my go-to dish for summer brunches and potlucks. I usually make an extra one to keep in the fridge for easy weekday lunches. Who doesn’t love having a ready-made meal waiting for them, especially one this good?

What Kind of Zucchini Should I Use?

For a quiche like this, medium-sized zucchini (about 7-8 inches long) are your best bet since they’re usually less watery and have smaller seeds than the jumbo ones you might find at the farmers’ market. Look for firm, dark green zucchini with smooth, unblemished skin – these will be the freshest and most flavorful. When you’re slicing them for the quiche, try to keep the thickness consistent (about 1/8 inch thick works well) so they cook evenly. If your zucchini seems extra watery after slicing, you can lay the pieces on paper towels and sprinkle them with a little salt for about 10 minutes to draw out excess moisture before adding them to your quiche.

Options for Substitutions

This quiche recipe is pretty adaptable and here’s what you can swap if needed:

• Phyllo dough: While phyllo gives this quiche its signature flaky texture, you can use regular pie crust or puff pastry instead. Just remember that the baking time might need to be adjusted slightly.
• Greek yogurt: No Greek yogurt? Regular sour cream works just as well. You could also use plain regular yogurt, but strain it first in a cheesecloth for about 30 minutes to remove excess water.
• Feta cheese: Feel free to swap feta with goat cheese or crumbled ricotta salata. If you’re not into strong-flavored cheeses, mild white cheddar works too.
• Fresh herbs: If fresh herbs aren’t available, use dried ones – just remember to use 1/3 of the amount called for (1 tsp dried chives, 1 tsp dried dill).
• Corn and zucchini: These veggies are pretty flexible – try asparagus, bell peppers, or mushrooms instead. Just make sure to cook them first and drain any excess moisture to prevent a soggy quiche.
• Cream: Half-and-half or whole milk can replace cream, though the filling won’t be quite as rich. If using milk, reduce the amount by 1 tablespoon.

Watch Out for These Mistakes While Baking

Working with phyllo dough can be tricky, so keep it covered with a slightly damp kitchen towel while you’re working – exposed phyllo dries out within minutes and becomes brittle and impossible to handle. The filling mixture needs careful attention too – avoid overmixing the eggs as this can lead to a tough, rubbery quiche; instead, whisk just until the ingredients are combined. When layering your vegetables, make sure to distribute the zucchini and tomato slices evenly and pat them dry with paper towels first, as excess moisture can make the bottom crust soggy. For the best results, let your eggs and dairy come to room temperature before mixing, and don’t skip brushing each phyllo layer with the butter-olive oil mixture – this creates that perfect flaky, golden crust that makes this quiche special.

What to Serve With Zucchini Phyllo Quiche?

This Mediterranean-inspired quiche pairs wonderfully with a simple mixed green salad dressed in a light lemon vinaigrette – the bright, fresh flavors balance out the rich, creamy eggs and buttery phyllo perfectly. For brunch, I love serving it alongside some fresh fruit like sliced melon or berries to add a sweet element to the plate. If you’re serving this for dinner, consider adding some roasted potatoes with herbs or a cup of light tomato soup on the side. The quiche already has lots of veggies built in, so keep the sides fairly simple to let it shine as the star of the meal.

Storage Instructions

Keep Fresh: Once your quiche has cooled completely, wrap it well in plastic wrap or place it in an airtight container. It’ll stay good in the fridge for up to 3 days. The phyllo might lose some of its crispiness over time, but the filling will remain delicious!

Freeze: This quiche freezes really well for up to 2 months. Just wrap individual slices or the whole quiche tightly in plastic wrap, then in foil. It’s super handy to have a few slices ready for quick meals!

Reheat: To bring back some of that phyllo crunch, reheat your quiche in a 350°F oven for about 15-20 minutes if it’s refrigerated, or 25-30 minutes if frozen (after thawing). You can also use the microwave for 1-2 minutes if you’re in a hurry, though the phyllo won’t be as crispy.

Make Ahead: You can prep this quiche the night before – just assemble everything except the phyllo layers, cover and refrigerate. Add the phyllo right before baking the next day. This way, you’ll get that perfect crispy crust!

Ingredients

For the filling:

• 1/4 cup crumbled feta cheese
• 1 tbsp Dijon mustard
• 3 tbsp chopped chives
• 4 tbsp heavy cream
• 1 tsp black pepper
• 1/4 cup plain Greek yogurt (full-fat preferred for richness)
• 1 tbsp fresh dill (finely chopped for best flavor)
• 7 large eggs
• 1 tsp sea salt

For the vegetables:

• 1 cup cooked corn kernels (Birds Eye is a good brand)
• 1 cup zucchini (shredded and squeezed dry)
• 1 large tomato (diced into 1/2-inch pieces)

For the phyllo crust:

• 1/4 cup unsalted butter (melted and cooled)
• 2 tbsp olive oil
• 5 phyllo dough sheets

Step 1: Prep Oven, Vegetables, and Dairy Mixture

• 7 large eggs at room temperature
• 4 tbsp heavy cream
• 1/4 cup plain Greek yogurt
• 1 tbsp dijon mustard
• 1 tsp sea salt
• 1 tsp freshly ground black pepper
• 3 tbsp chopped chives
• 1 tbsp fresh dill
• 1/4 cup feta cheese, crumbled
• 1 cup cooked corn kernels
• 1 large tomato, thin slices
• 1 cup zucchini, thin rounds

Preheat your oven to 350°F.

Cut the corn kernels off the cob and place them in a small bowl.

Slice the tomato into thin slices and the zucchini into thin rounds; set both aside.

In a large bowl, whisk together the eggs, heavy cream, Greek yogurt, and dijon mustard until smooth.

Season this mixture with sea salt and freshly ground black pepper.

Stir in the chopped chives, fresh dill, and crumbled feta cheese until well combined.

Step 2: Prepare Phyllo Pastry and Pan

• 1/4 cup unsalted butter, melted
• 2 tbsp olive oil
• 5 phyllo dough sheets

Mix the melted unsalted butter and olive oil in a small bowl.

Brush the bottom and sides of a 7-inch springform pan with some of this mixture.

Keep the phyllo dough sheets covered with a kitchen towel so they don’t dry out.

Working with one sheet at a time, brush each sheet of phyllo on both sides with the butter-oil mixture.

Lay each sheet into the springform pan, gently pressing and folding the edges over the top as needed.

Layer all 5 sheets this way; it’s perfectly fine if some tear.

I like to press the edges firmly against the sides to create a sturdy crust.

Step 3: Assemble the Quiche

• egg, cream, yogurt, mustard, herbs, and feta mixture from Step 1
• phyllo-lined pan from Step 2
• 1 cup cooked corn kernels (divided, from Step 1)
• 1 large tomato, thin slices (divided, from Step 1)
• 1 cup zucchini, thin rounds (from Step 1)

Pour one third of the egg and cheese mixture (from Step 1) into the prepared phyllo-lined pan.

Scatter half of the corn kernels and half of the tomato slices evenly over the mixture.

Pour in another third of the egg mixture, then layer all the zucchini slices on top.

Pour the last third of the egg mixture over the zucchini.

Finish by topping with the remaining corn and tomato slices, along with any extra zucchini rounds.

Step 4: Bake the Quiche

Place the assembled quiche in the preheated oven and bake for 40-45 minutes, until the phyllo pastry is golden and crisp.

Cover the pan loosely with aluminum foil and continue baking for an additional 15-20 minutes, or until the egg custard has completely set.

Switch off the oven, but let the quiche rest inside for 10 more minutes to finish setting gently.

I find that letting it rest in the turned-off oven helps avoid cracks and ensures the filling is silky.

Step 5: Cool and Unmold

Remove the springform pan from the oven and let the quiche cool on the counter for 5-10 minutes.

Carefully release it from the pan and transfer to a serving platter.

Slice and enjoy while warm or at room temperature.

For a little extra flavor, I like to sprinkle a few more fresh chives or dill on top before serving.
