Ingredients
2 cups/255 grams unbleached all-purpose flour
2 tablespoons granulated sugar
1 teaspoon baking powder
Kosher salt
10 tablespoons/140 grams cold unsalted butter, cut into cubes
1 ½ teaspoons balsamic vinegar
1 large egg, yolk and white separated
Ice water, as needed
1 tablespoon extra-virgin olive oil
1 large onion, halved and very thinly sliced
2 fresh thyme sprigs
1 fresh or dried bay leaf
1 teaspoon honey
Freshly ground black pepper
1 tablespoon poppy seeds
3 ounces good-quality feta or goat cheese, crumbled (about ½ cup)
Preparation
- Step 1
Mix the flour, sugar, baking powder and 1 teaspoon salt in the bowl of a food processor. Add 9 tablespoons butter and pulse until coarse crumbs form. Add ½ teaspoon balsamic vinegar and the egg yolk and pulse, adding 2 to 3 tablespoons or so of ice water if needed to form a soft dough. Wrap the dough in waxed paper or plastic wrap and refrigerate, about 30 minutes.
- Step 2
Meanwhile, heat the oil and the remaining 1 tablespoon butter in a medium nonstick pan over medium-low. Add the onion, thyme, bay leaf and honey, season with salt and pepper and cook, stirring occasionally, until caramelized, about 20 minutes. Discard the thyme sprigs and bay leaf. Stir in the poppy seeds and the remaining 1 teaspoon balsamic vinegar and season to taste. Let cool.
- Step 3
Remove the dough from the fridge, heat the oven to 375 degrees and cover 2 large baking sheets with parchment paper.
- Step 4
Roll out the dough onto a floured surface until ⅛ inch thick. Using a 2 ½-inch round mold or glass, cut the dough into rounds. Top each round with a hefty pinch of cheese in the center, then a heaping teaspoon of the cooled onion mixture. Working with one round at a time, dip a pastry brush or your finger into the egg white and moisten the edges of the excess dough surrounding the filling. Fold up 3 sides of the round to form a triangle, partly covering the filling with the dough, and pinch the dough firmly at all 3 tips of the triangle. Transfer to the parchment-lined baking sheets and repeat to make about 36 hamantaschen.
- Step 5
Bake until golden, rotating midway through baking, 15 to 20 minutes, then serve warm.

Ate a few. Still alive.
Onion filling is great! No fresh thyme so made it with a little dried chopped thyme. I made half the hamantaschen with jam filling; also delicious. Problem dough recipe, though: Either too much flour or needing a whole lot more water. Even with double the water the dough was still crumbly. If making the full recipe, pull only half of the dough out of the fridge at a time because if it's too warm when the pastry goes into the oven, it looses its triangle shape.
hi Judith- I can assume that the dough that was chilled 1 hour was just a bit too cold and expanded more as a reaction to the more extreme temp. change. The moisture that was captured in the dough had trouble escaping as it baked so it produced steam and puffed, causing the triangles to open. I'm sure your next batch will be perfect!
I made these with black sesame seeds because I couldn't find poppy seeds at my local market. They came out delicious and were a big hit at my women's book group!
I'd like to prep the dough and filling the night before, then assemble and bake in the morning for a brunch. will that work? sounds like this dough is quite finicky based on temperature. thanks for any advice!
Cheated: Used Just-Rol pre-rolled thin pizza dough from the dairy case. Perfect. and Delice de Bourgogne instead of feta.
