Galaktoboureko Recipe

Warm the milk

In a medium saucepan, combine the 4 cups whole milk and 1 cup sugar. Warm over medium heat until the sugar dissolves and the milk is hot but not boiling (small bubbles forming at the edges), about 5–7 minutes. Stir occasionally.

Mix dry thickener

In a bowl, whisk together 1 cup semolina, 2 tablespoons flour and 1 teaspoon salt until evenly combined.

Temper and thicken

Whisk the dry semolina mixture into the hot milk slowly. Continue to cook over medium-low heat, stirring constantly with a whisk or wooden spoon so the semolina doesn't clump. Simmer gently until the mixture thickens to a loose porridge consistency, about 6–8 minutes.

Temper eggs

In a separate bowl, lightly beat 3 large eggs. Ladle about 1 cup of the hot semolina mixture into the eggs while whisking vigorously to temper. Then pour the tempered eggs back into the pot, stirring constantly. Cook another 2–3 minutes until the custard thickens further and holds on the spoon.

Finish custard

Remove the pot from the heat. Stir in 4 tablespoons room-temperature butter, 2 teaspoons vanilla extract and 1 tablespoon finely grated lemon zest until smooth and glossy. Taste and adjust salt or zest if desired. Let cool slightly (10 minutes).

Prepare pan and phyllo

Preheat oven to 350°F (175°C). Lightly grease a 9x13-inch (or similar) baking dish with a little melted butter. Have your phyllo sheets covered with a damp towel to prevent drying.

Layer bottom sheets

Place one phyllo sheet in the dish, brush lightly with melted butter (about 1 tablespoon). Repeat layering 5 more sheets, brushing each with butter as you go. Brush the topmost sheet and sprinkle about 1 teaspoon granulated sugar evenly over the layered sheets.

Add custard

Pour the warm (not piping hot) custard into the prepared phyllo-lined pan and spread evenly with a spatula. The custard should come close to the pan edges but leave a small margin to prevent leakage when baking.

Top layers

Layer the remaining 6 phyllo sheets over the custard. For each sheet, brush with melted butter (and a little vegetable oil if using) before laying the next. Brush the final top sheet generously with butter. Using a sharp knife, score the top through the phyllo into diamond or square pieces down to the custard (this helps cutting later). Sprinkle the surface with the remaining 1 teaspoon sugar.

Bake

Bake in the preheated oven for 35–45 minutes, or until the phyllo is deep golden brown and crisp and the custard is set (it will still have slight give but not be liquid). Rotate the pan halfway through for even browning.

Make syrup

While the galaktoboureko bakes, combine 1 cup water, 1 cup sugar, 2 tablespoons honey, and the optional cinnamon stick in a small saucepan. Bring to a boil over medium heat, stirring until the sugar dissolves. Reduce heat and simmer gently for 6–8 minutes to slightly thicken. Remove from heat and stir in 1 tablespoon lemon juice and 1 teaspoon vanilla extract. Remove the cinnamon stick and let the syrup cool to warm (not icy cold).

Pour syrup

When the galaktoboureko is out of the oven, wait 5 minutes so it stops sizzling but is still hot. Using a ladle, pour the warm syrup evenly over the hot pastry, following the scored lines so the syrup penetrates. Use all the syrup; it will soak into the phyllo and custard, sweetening and giving the characteristic glaze. Let cool completely (at least 1–2 hours) at room temperature to set; refrigeration not required but you can chill before serving if you prefer.

Serve

Once set, cut fully through the scored lines with a sharp knife and serve slices at room temperature. Galaktoboureko is best the day it is made or within 24 hours; beyond that phyllo can soften. Store covered at room temperature for up to 24 hours or refrigerated for up to 3 days (bring to room temperature before serving).
