📝 About This Recipe

Inspired by the classic Jewish bakeries of New York, these onion rolls feature a pillowy, enriched dough infused with the savory sweetness of slow-cooked onions. Each bun is topped with a signature 'onion well' filled with pungent dried onions and crunchy poppy seeds, creating a perfect balance of textures. Whether used for a deli sandwich or enjoyed warm with salted butter, these rolls are a masterclass in bread-making comfort.

🥗 Ingredients

The Enriched Dough

  • 4 1/2 cups Bread Flour (high protein for better structure)
  • 1 cup Whole Milk (warmed to 110°F)
  • 2 1/4 teaspoons Instant Yeast (one standard packet)
  • 3 tablespoons Granulated Sugar
  • 6 tablespoons Unsalted Butter (softened to room temperature)
  • 1 Large Egg (at room temperature)
  • 2 teaspoons Kosher Salt

The Onion Filling & Topping

  • 1 large Yellow Onion (finely minced)
  • 1/4 cup Dried Minced Onions (rehydrated in 2 tbsp hot water)
  • 2 tablespoons Poppy Seeds
  • 2 tablespoons Vegetable Oil
  • 1 Egg White (beaten with 1 tsp water for the wash)
  • 1/2 teaspoon Flaky Sea Salt (for finishing)

👨‍🍳 Instructions

  1. 1

    In the bowl of a stand mixer, combine the warm milk, sugar, and instant yeast. Let it sit for 5-10 minutes until it becomes slightly foamy.

  2. 2

    Add the egg and 2 cups of the bread flour to the yeast mixture. Using the paddle attachment, mix on low speed until a thick batter forms.

  3. 3

    Switch to the dough hook. Add the remaining flour and the kosher salt. Knead on medium-low speed for 5 minutes until the dough starts to pull away from the sides of the bowl.

  4. 4

    Add the softened butter one tablespoon at a time, allowing each piece to incorporate fully before adding the next. Continue kneading for 5-7 minutes until the dough is smooth, elastic, and passes the windowpane test.

  5. 5

    Place the dough in a lightly greased bowl, cover with plastic wrap, and let rise in a warm, draft-free spot for 60-90 minutes, or until doubled in size.

  6. 6

    While the dough rises, heat the vegetable oil in a skillet over medium-low heat. Sauté the fresh minced onions until they are soft and golden brown (about 10-12 minutes). Remove from heat and stir in the rehydrated dried onions and poppy seeds. Let this mixture cool completely.

  7. 7

    Gently punch down the risen dough and turn it out onto a lightly floured surface. Divide the dough into 12 equal pieces (roughly 85-90g each).

  8. 8

    Roll each piece into a smooth ball. Place them on two parchment-lined baking sheets, spacing them at least 3 inches apart.

  9. 9

    Flatten each ball slightly with the palm of your hand. Cover loosely with a clean kitchen towel and let rise for another 45 minutes.

  10. 10

    Preheat your oven to 375°F (190°C). Using your thumb or the back of a small spoon, press a deep indentation into the center of each risen roll.

  11. 11

    Brush the edges of the rolls with the egg white wash. Fill each center indentation generously with the onion and poppy seed mixture.

  12. 12

    Bake for 20-25 minutes, rotating the pans halfway through, until the rolls are a deep golden brown and the onions are fragrant.

  13. 13

    Remove from the oven and immediately sprinkle with a pinch of flaky sea salt. Transfer to a wire rack to cool slightly before serving.

💡 Chef's Tips

Always use bread flour rather than all-purpose for that signature chewy, bakery-style texture. Don't skip the rehydrated dried onions; they provide a concentrated 'toasty' flavor that fresh onions alone can't achieve. If the dough is too sticky during the second knead, add flour 1 tablespoon at a time, but be careful not to over-flour or the rolls will be dense. For an extra-glossy finish, you can use a whole egg wash instead of just egg whites. To store, keep in an airtight bag for up to 3 days, or freeze for up to a month and reheat in a 300°F oven.

🍽️ Serving Suggestions

Serve warm with a thick schmear of whipped cream cheese or salted Irish butter. Use as the base for a classic Hot Pastrami or Corned Beef sandwich with spicy brown mustard. Pair with a bowl of homemade Matzo Ball soup or a hearty Beef Stew. Excellent alongside a crisp lager or a glass of iced tea with lemon. Slice and toast the next day for a savory breakfast sandwich with soft scrambled eggs.
