This Greek custard tart layers silky semolina custard in crisp, buttered phyllo and finishes with a fragrant lemon syrup. It is inspired by galaktoboureko, a well-known Greek pastry; recipes vary, and this version is baked in a tart pan for easy slicing.
Ingredients
- 1 package phyllo dough, about 16 oz (450 g), thawed overnight in the refrigerator
- 10 tablespoons unsalted butter, 1¼ sticks (140 g), melted, plus extra for the pan
- 4 cups whole milk (960 ml)
- ¾ cup granulated sugar (150 g), for the custard
- ⅔ cup fine semolina (110 g)
- 4 large eggs (about 200 g without shells), at room temperature
- 2 tablespoons unsalted butter (28 g), for the custard
- 1 teaspoon finely grated lemon zest (about 2 g)
- 1 teaspoon vanilla extract (5 ml)
- ¼ teaspoon fine salt (1.5 g)
- 1 cup granulated sugar (200 g), for the syrup
- ½ cup water (120 ml)
- 1 tablespoon lemon juice (15 ml)
- 1 small strip lemon peel, about 2 inches (5 cm)
- 1 small cinnamon stick (about 7 g)
Instructions
- Thaw and prepare. If frozen, thaw the phyllo in the refrigerator overnight, following the package directions. Set it on the counter for about 30 minutes so the sheets are easier to handle. Heat the oven to 350°F (175°C). Butter a 9-inch (23 cm) round tart pan, preferably one with a removable bottom, and set it on a rimmed baking sheet.
- Cook the custard base. Warm the milk and ¾ cup (150 g) sugar in a medium saucepan over medium heat until steaming but not boiling, stirring to dissolve the sugar. Slowly whisk in the semolina and salt. Cook, whisking constantly, for 5–7 minutes, until thick and smooth. Remove from the heat and stir in the 2 tablespoons (28 g) butter, lemon zest, and vanilla. Let the mixture cool for 10 minutes, stirring occasionally.
- Add the eggs. In a bowl, whisk the eggs. Whisk a ladleful of the warm semolina mixture into the eggs to temper them, then gradually whisk the egg mixture back into the saucepan. Keep the custard warm rather than hot so the eggs blend in without scrambling. The tart will be baked until its center reaches 160°F (71°C), the USDA FSIS safe minimum temperature for egg dishes.
- Line the pan. Unroll the phyllo and keep it covered with a barely damp towel while you work; uncovered sheets dry and crack quickly. Lay one sheet in the pan with the edges hanging over the rim, brush it lightly with melted butter, and rotate the pan slightly. Repeat with 7 more sheets, staggering their placement so the base and sides are covered. Avoid pressing or tearing the sheets more than necessary.
- Fill and finish the crust. Pour the custard into the phyllo-lined pan and smooth the top. Fold the overhanging phyllo over the filling in loose, overlapping folds. Lay 3 more sheets over the top, brushing each with butter and gently tucking the edges into the pan. Brush the top generously with the remaining butter. With a sharp knife, score the top phyllo into 10 portions without cutting deeply into the custard.
- Bake. Bake on the baking sheet for 45–55 minutes, until the phyllo is deeply golden and crisp and the center is set, not liquid. For an accurate safety check, insert a food thermometer into the custard at the center; it must reach 160°F (71°C). If the top browns too quickly before the custard is set, loosely cover it with foil. Begin checking at 45 minutes.
- Make the syrup. While the tart bakes, combine the syrup sugar, water, lemon juice, peel, and cinnamon stick in a small saucepan. Bring to a boil, stirring just until the sugar dissolves, then simmer for 4 minutes. Remove from the heat and discard the peel and cinnamon. Let the syrup cool while the tart finishes baking.
- Cool and serve. Set the baked tart on a rack for 15 minutes, then spoon the cool syrup evenly over the warm pastry. Cool for at least 1 hour before removing the pan sides and slicing. The total time includes the 30-minute phyllo rest, 10-minute custard cool, 45-minute minimum bake, and 1-hour cooling; a longer bake extends the total accordingly.
Tips
- Thaw phyllo slowly in the refrigerator and bring it to room temperature before opening. If sheets tear, patch them with another buttered piece; the layered pastry is forgiving.
- Fine semolina gives the custard its characteristic tender, lightly grainy body. If unavailable, use an equal weight of fine cream-of-wheat cereal; the texture may be a little softer. Coarse semolina can make the filling gritty.
- Temper the eggs gradually and whisk constantly when adding them back to the warm custard. Adding eggs directly to very hot milk can cook them into lumps.
- Use a thermometer rather than relying on browning alone: phyllo can color before the custard center is safely set. Keep the tart on a rimmed sheet in case butter or syrup escapes.
Serving Suggestions
Serve slices at room temperature, when the custard is set but still creamy and the phyllo stays crisp. Strong Greek coffee or unsweetened black tea balances the buttery pastry. For a simple dessert plate, add fresh berries or a few orange segments; keep extra syrup at the table so guests can choose how sweet they want each slice.
Variations
For a more traditional galaktoboureko-style finish, use a rectangular baking dish and arrange the phyllo in larger, loose folds over the custard. Add ½ teaspoon (1 g) ground cinnamon to the syrup, or replace the lemon peel with a strip of orange peel for a rounder citrus aroma. A little rose water can replace the vanilla, but use only ½ teaspoon (2.5 ml) so it does not overpower the custard. For a less sweet tart, reduce the syrup sugar to ¾ cup (150 g); the pastry will have a lighter glaze, while the custard itself remains unchanged.
Storage and Reheating
Cool the tart, then refrigerate it within 2 hours of baking in a covered container or loosely covered with plastic wrap. Keep it refrigerated for up to 3–4 days. The phyllo softens as it absorbs moisture, so this tart is crispest on the day it is made. To reheat, warm individual slices in a 300°F (150°C) oven for 8–12 minutes, until heated through; avoid the microwave if you want to preserve some crispness. Reheat leftovers to 165°F (74°C), as recommended for food safety. Do not leave the egg-and-milk filling at room temperature for more than 2 hours total.
Frequently Asked Questions
Can I make this tart ahead?
Yes. Bake it, cool it, and refrigerate it for up to 3–4 days. For the best contrast between crisp pastry and creamy filling, make it the same day you plan to serve it, or rewarm slices briefly in the oven.
Can I use frozen phyllo straight from the freezer?
No. Frozen sheets are brittle and likely to crack. Thaw them in the refrigerator overnight, then allow about 30 minutes at room temperature before unfolding. Do not force sheets apart while they are still frozen.
Why is my custard lumpy?
Semolina can clump if added all at once or if it is not whisked continuously. Sprinkle it gradually into steaming milk while whisking, and keep stirring as it thickens. If a few small lumps remain, whisk vigorously before tempering in the eggs.
How do I know when the tart is done?
The top should be golden and crisp, and the custard should no longer look liquid in the center. Check the center with a food thermometer: egg dishes need to reach 160°F (71°C). The filling firms further as it cools.
Can I freeze Greek custard tart?
Freezing is not ideal because thawed custard can turn grainy and phyllo loses its crisp texture. Refrigerate leftovers instead, and use them within 3–4 days.
Do I have to use syrup?
No, but the syrup is a defining feature of galaktoboureko-inspired pastries and adds sweetness and moisture. You can drizzle on only half for a less-sweet finish, or serve the cooled syrup on the side.
