Irresistible Spinach and Feta Phyllo Quiche

Looking for a showstopping brunch dish that seems fancy but won’t leave you stressed in the kitchen? I get it – we all want to serve something that looks impressive without spending hours on complicated techniques or hunting down obscure ingredients.

That’s exactly why this spinach and feta phyllo quiche has become one of my most-requested recipes. The flaky phyllo crust gives you that wow-factor presentation, while the creamy spinach and feta filling comes together with straightforward, supermarket-friendly ingredients. Plus, you can assemble it the night before and just pop it in the oven when you’re ready, making it perfect for lazy weekend mornings or when you’re hosting guests.

What Kind of Spinach Should I Use?

Fresh spinach is definitely the way to go for this phyllo quiche, and you have a couple of options at the grocery store. Baby spinach is probably the easiest choice since the leaves are tender and don’t require much prep work beyond a quick rinse and rough chop. Regular mature spinach works great too, though you’ll want to remove any thick stems before chopping. If you’re in a pinch, frozen spinach can work, but make sure to thaw it completely and squeeze out as much water as possible – excess moisture can make your quiche soggy. One pound of fresh spinach might seem like a lot at first, but don’t worry, it cooks down significantly once it hits the pan.

Options for Substitutions

This quiche is pretty forgiving when it comes to swapping ingredients:

• Phyllo pastry: This is the base of the quiche, so you’ll want to stick with phyllo for that crispy, flaky texture. However, if you’re short on time, you can use a store-bought pie crust instead – just skip the butter brushing and breadcrumb steps.
• Spinach: Fresh spinach works best, but you can use 10 oz of frozen spinach if needed. Just make sure to thaw it completely and squeeze out all the excess water before adding it to the filling.
• Feta cheese: Goat cheese or ricotta can work in place of feta if you want a milder, creamier taste. You might want to add a pinch of extra salt since these cheeses are less salty than feta.
• Half and half: You can use whole milk for a lighter version, or heavy cream for something richer. A mix of milk and cream also works great.
• Mozzarella, Gruyère, or Gouda: Any good melting cheese will do here – try cheddar, Swiss, or even Monterey Jack. Pick whatever you have in your fridge.
• Scallions: Regular yellow or white onion can replace scallions, or try leeks for a similar mild onion flavor. Just use about ½ cup chopped.

Watch Out for These Mistakes While Baking

The biggest mistake when working with phyllo dough is letting it dry out, which causes it to crack and become impossible to work with – keep unused sheets covered with a damp towel while you’re layering.

Another common error is not cooking the spinach long enough to release its moisture, which can lead to a watery quiche, so make sure to cook it until wilted and let any excess liquid evaporate in the pan.

Don’t skip brushing butter between each phyllo layer, as this is what creates those crispy, flaky layers instead of a tough, chewy crust.

Finally, resist the urge to cut into the quiche right away – letting it rest for the full 20 minutes allows the custard to set properly, making it much easier to slice clean pieces without everything falling apart.

What to Serve With Spinach and Feta Phyllo Quiche?

This quiche is perfect for brunch or a light dinner, and I love serving it with a simple arugula salad tossed with lemon juice and olive oil to balance out the richness of the phyllo and cheese. A bowl of fresh fruit like berries or melon slices makes a great side if you’re serving this for breakfast or brunch. For a heartier meal, roasted cherry tomatoes or a cucumber and tomato salad with red onion and a light vinaigrette work really well alongside the savory spinach and feta flavors. You could also serve it with some crusty bread or pita chips if you want something to munch on between bites.

Storage Instructions

Store: This quiche keeps really well in the fridge for up to 4 days. Just cover it tightly with plastic wrap or aluminum foil, or transfer slices to an airtight container. It’s great for meal prep since you can grab a slice for breakfast or lunch throughout the week.

Freeze: You can freeze the whole quiche or individual slices for up to 2 months. Wrap it well in plastic wrap and then in foil to prevent freezer burn. I like to freeze individual portions so I can just grab one when I need a quick meal.

Reheat: Warm up slices in the oven at 350°F for about 15-20 minutes until heated through, or use the microwave for 1-2 minutes. The oven method keeps the phyllo crispier, but the microwave works fine when you’re in a hurry. If reheating from frozen, let it thaw in the fridge overnight first for best results.

• Calories: 2600-2900
• Protein: 80-90 g
• Fat: 170-190 g
• Carbohydrates: 190-210 g

Ingredients

For the crust:

• 4 oz salted butter (melted for brushing between layers)
• 1/2 cup breadcrumbs (helps absorb moisture and adds structure)
• 1/2 lb phyllo pastry (thaw if frozen, handle gently to prevent tearing)

For the spinach filling:

• 1 small onion (finely diced, about 1/2-inch pieces)
• salt to taste
• 8 oz feta cheese (crumbled into bite-sized pieces)
• 3 tbsp olive oil
• 1 roasted red pepper (jarred or fresh, chopped into 1/2-inch pieces)
• 2 scallions (white and light green parts, chopped into 1/4-inch pieces)
• 1 lb spinach (roughly chopped, fresh or thawed frozen)
• black pepper to taste

For the custard:

• 6 oz shredded mozzarella (I use Kraft for consistent melting)
• salt to taste
• black pepper to taste
• 2 large eggs (room temperature for best emulsification)
• 1/8 tsp ground nutmeg (freshly grated preferred for more flavor)
• 1.25 cups half and half

Step 1: Prepare Mise en Place and Preheat

• 1 small onion
• 2 scallions
• 1 lb spinach
• 8 oz feta cheese
• 1 roasted red pepper
• 6 oz shredded mozzarella
• 4 oz salted butter

Preheat your oven to 350°F.

While it heats, prepare all your ingredients: finely dice the onion, chop the scallions (keeping white and light green parts separate from darker greens), roughly chop the spinach (if using fresh, or thaw frozen spinach and squeeze out excess moisture), crumble the feta into bite-sized pieces, chop the roasted red pepper into 1/2-inch pieces, and shred the mozzarella.

Melt the butter and keep it warm for brushing.

Having everything ready before you start cooking ensures you can work smoothly through the filling and assembly stages.

Step 2: Cook the Spinach Filling Base

• 3 tbsp olive oil
• 1 small onion, finely diced
• 2 scallions
• 1 lb spinach
• salt to taste
• black pepper to taste

Heat the olive oil in a large skillet over medium-high heat.

Add the diced onion and cook for 8 minutes, stirring occasionally, until softened and beginning to turn golden.

Add the white and light green parts of the scallions and cook for 2 minutes.

Now add the spinach, salt, and black pepper, stirring frequently until the spinach is completely wilted and any excess moisture has evaporated—this should take about 5-7 minutes depending on whether you started with fresh or frozen spinach.

Remove from heat and let cool slightly.

Step 3: Complete the Filling and Prepare the Pan

• cooked spinach mixture from Step 2
• 8 oz feta cheese, crumbled
• 1 roasted red pepper, chopped
• 4 oz salted butter
• 1/2 cup breadcrumbs

Stir the crumbled feta and chopped roasted red pepper into the cooled spinach mixture from Step 2.

Set the filling aside.

Lightly brush a 9×13 inch baking dish (or similar-sized casserole) with melted butter, then sprinkle the breadcrumbs evenly across the bottom—the breadcrumbs act as a moisture barrier to keep the phyllo crust from getting soggy.

I like to use breadcrumbs here rather than skipping this step because they truly make a difference in maintaining a crispy phyllo base throughout baking.

Step 4: Layer and Butter the Phyllo Crust

• 1/2 lb phyllo pastry
• 4 oz salted butter

Working gently to avoid tearing, begin layering the phyllo sheets into the prepared baking dish.

Brush each sheet lightly but thoroughly with melted butter before adding the next layer.

You’ll want to use about half the phyllo package (roughly 8-10 sheets) to create the bottom crust—each brushed sheet adds structural support and creates that delicate, flaky texture.

The butter between layers is what transforms phyllo into something golden and crispy, so don’t skip this step or be too timid with the brushing.

Step 5: Make the Egg Custard and Assemble

• 2 large eggs
• 1.25 cups half and half
• 1/8 tsp ground nutmeg
• salt to taste
• black pepper to taste
• spinach and feta filling from Step 3
• 6 oz shredded mozzarella

In a bowl, whisk together the eggs, half and half, ground nutmeg, salt, and black pepper until well combined and smooth.

Pour this custard mixture into the phyllo-lined pan, spreading it evenly.

Then distribute the spinach and feta filling from Step 3 over the custard layer, and sprinkle the shredded mozzarella on top.

The custard will partially cook the filling and keep everything moist, while the mozzarella will melt and bind everything together.

Step 6: Seal the Top Crust and Bake

• 4 oz salted butter
• 1/2 lb phyllo pastry

Fold the edges of the phyllo sheets from the bottom layer up and over the filling to partially cover the top, creating a rustic, loosely enclosed appearance.

Brush this folded top generously with the remaining melted butter.

Layer the remaining phyllo sheets on top (about 8-10 sheets), brushing each one with butter just as you did with the bottom layers, then brush the final top layer generously with butter for a beautiful golden finish.

Bake for 45 minutes, or until the phyllo is deep golden brown and a knife inserted into the center comes out hot, indicating the custard is set.

Step 7: Cool and Serve

Remove the quiche from the oven and let it cool for at least 20 minutes before cutting and serving.

This resting period allows the custard to fully set and the phyllo to crisp up further, making it much easier to slice cleanly without the filling running out.

The quiche can be served warm or at room temperature, making it perfect for meals throughout the day.
