Lemon phyllo pie is a baked custard pie with layers of crisp, buttery phyllo on top and bottom, and a soft lemon custard set in the middle. Once it comes out of the oven, I pour a hot lemon syrup right over the top so it soaks all the way through.
The custard is made with the same semolina used in Greek honey cake, milk, eggs, and plenty of lemon zest, so it turns out thick and a little bouncy, not runny. The phyllo on top bakes up crisp and flaky, then softens just slightly once the syrup goes on.
This is close to a Greek galaktoboureko, but I lean harder into the lemon here, in the custard and in the syrup. It’s a good dessert for a dinner party because you can make it a few hours ahead and let it sit at room temperature.
One thing I learned by messing this up once: pour the syrup on while the pie is still hot from the oven. Cold syrup on a cold pie just sits on top instead of soaking in.

- Hot syrup soak keeps every bite moist
- Make it a few hours ahead for a dinner party
Ingredient Notes
- Whole milk: Use whole milk for a thick custard. Low-fat milk works but the filling turns out thinner.
- Fine semolina: This is what sets the custard so it slices cleanly. Fine semolina works better than coarse here, it blends in without gritty bits.
- Phyllo sheets: Keep unused sheets under a damp towel while you work, they dry out and crack fast once exposed to air.
- Lemon zest and juice: Use fresh lemons for the zest, since bottled juice has none. Bottled juice is fine for the syrup if that’s what you have.
- Unsalted butter: Melted butter brushed between every phyllo sheet is what makes the top crisp instead of chewy.

Ingredients
Method
- Heat the milk in a 3-quart / 2.8 L saucepan over medium heat until steaming but not boiling, 4 to 5 minutes.
- Whisk the semolina into the hot milk gradually, stirring constantly to avoid lumps. Cook over medium-low heat for 5 to 6 minutes, stirring, until it thickens like a loose pudding.
- In a separate bowl, whisk the eggs and sugar until pale. Temper by adding a spoonful of the hot semolina mixture at a time, whisking, until warmed through.
- Pour the egg mixture back into the saucepan. Cook over low heat for 2 to 3 minutes, stirring constantly, until the custard coats the back of a spoon and no longer tastes of raw egg. Remove from heat and stir in the butter, lemon zest, vanilla, and salt. Set aside to cool for 5 minutes.
- Heat the oven to 180 C / 350 F and butter a 33 x 23 cm / 9 x 13-inch baking dish.
- Layer 5 phyllo sheets in the dish, brushing each sheet with melted butter before adding the next, letting the edges hang over the sides.
- Pour the cooled custard over the phyllo base and spread it evenly with a spatula.
- Cover with the remaining 5 phyllo sheets, brushing each with butter. Tuck or trim the overhanging edges. Score the top layer into 12 squares with a sharp knife, this makes cutting easier later and helps the syrup soak in.
- Bake for 40 to 45 minutes, until the top is golden brown and the custard doesn't jiggle when you shake the pan gently.
- While the pie bakes, combine the sugar, water, lemon juice, and lemon peel in a 1-quart / 1 L saucepan. Simmer over medium heat for 5 to 6 minutes, until slightly syrupy. Remove the peel.
- As soon as the pie comes out of the oven, pour the hot syrup evenly over the hot pie. Let it sit for at least 60 minutes so the syrup soaks in before cutting.
- Cut along the scored lines and serve warm or at room temperature.
Notes
- Cool the custard for 5 minutes before assembling, or the phyllo underneath gets soggy.
- Pour syrup over the pie right out of the oven, not after it cools.
- Score the top layer before baking so it's easier to cut cleanly.
- Keep phyllo covered with a damp towel while you work, so it doesn't dry out and crack.
Tips for Success
- Let the custard cool for 5 minutes before pouring it over the phyllo base, or the bottom layer turns soggy.
- Brush every single phyllo sheet with melted butter, not just every other one, so each layer crisps in the oven.
- Pour the syrup over the pie while both are still hot, so it soaks all the way through like the syrup-brushed tahini rolls instead of sitting on top.
- Score the top phyllo layer into squares before baking so you can cut clean pieces once it cools.
- Whisk the semolina into the hot milk slowly to avoid lumps, or strain the custard before pouring it into the dish.
Variations
- Swap half the lemon juice for orange juice in the syrup for a softer, less tart finish.
- Add a few tablespoons of shredded coconut to the custard for a lightly nutty, sweet edge.
- Use a mix of lemon and lime zest in the custard for a sharper citrus flavor.
Storage and Reheating
Lemon phyllo pie keeps well because the syrup soak protects the phyllo from drying out. Store it covered at room temperature for up to 2 days, or in the fridge for up to 4 days.
I don’t reheat this pie in the oven, since the extra heat dries out the custard and makes the phyllo go tough instead of crisp. Let a cold slice sit at room temperature for 20 to 30 minutes before eating, or eat it straight from the fridge if you like it cold.
This pie doesn’t freeze well. The custard turns watery once it thaws, and the phyllo loses its texture completely.
Serving Suggestions
Lemon phyllo pie works as a dessert on its own, but I like to add a small scoop of vanilla ice cream or a dollop of Greek yogurt next to a warm slice.
A cup of strong coffee or a pot of mint tea makes a good pairing, since the bitterness balances the sweet syrup.
For a spring or summer table, add a handful of fresh berries or a few thin lemon slices on the plate for color.
FAQ
Why is my lemon phyllo pie soggy on the bottom instead of crisp?
Your lemon phyllo pie turns soggy on the bottom when the custard goes in too hot or you skip buttering every phyllo layer underneath. Let the custard cool for 5 minutes before pouring it over the base, and brush each of the 5 bottom sheets with melted butter so they crisp instead of steaming. Baking on a lower oven rack also helps the base brown fully.
Can I use bottled lemon juice instead of fresh lemons in the syrup?
Yes, bottled lemon juice works fine in the syrup, though fresh juice tastes brighter and less sharp. Stick with fresh lemons for the zest in the custard, since bottled juice won’t give you any zest at all. If you only have bottled juice, use the same 60 ml amount called for in the syrup.
Can I make lemon phyllo pie ahead of time, and how do I store leftovers?
You can make lemon phyllo pie a day ahead since the syrup soak actually improves the texture overnight. Store it covered at room temperature for up to 2 days, or in the fridge for up to 4 days. Bring refrigerated slices to room temperature before serving so the phyllo doesn’t taste cold and stiff.
What goes well with lemon phyllo pie?
Lemon phyllo pie pairs well with a scoop of vanilla ice cream or a dollop of plain Greek yogurt to balance the sweetness. A cup of strong coffee or mint tea also works, since the bitterness cuts through the lemon syrup. Fresh berries on the side add a little extra tartness.
Is lemon phyllo pie gluten-free?
No, lemon phyllo pie is not gluten-free because both the semolina in the custard and the phyllo sheets are made from wheat. There isn’t a simple swap here, since semolina gives the custard its thick texture and phyllo can’t be replaced with a gluten-free sheet without changing the whole pie. Skip this one if you need gluten-free.
What’s the difference between lemon phyllo pie and galaktoboureko?
Lemon phyllo pie is close to Greek galaktoboureko, but galaktoboureko usually leans on vanilla and a plain sugar syrup, while this version pushes lemon into both the custard and the syrup. The phyllo and semolina custard base are the same idea. Think of this as a lemon-forward take on that classic pie.
