Turn discard into divine! Get soft, airy, lightly tangy hamburger buns easily. This recipe uses active yeast for a guaranteed rise and perfectly kneaded dough.

Ingredients

  • Sourdough DiscardUse unfed discard directly from your refrigerator. This provides flavor and a slight leavening boost without the full-on sourdough commitment.
  • Warm MilkWhole milk or a plant-based alternative like almond or soy milk works best to activate the yeast and enrich the dough. Ensure it's between 105-115°F (40-46°C).
  • Granulated SugarA touch of sugar feeds the yeast, aids in browning, and balances the sourdough tang. Don't worry, the buns won't taste sweet.
  • Active Dry YeastEven with sourdough discard, a small amount of commercial yeast ensures a consistent rise and a reliably fluffy texture.
  • All-Purpose FlourStandard all-purpose flour provides the right structure for soft, airy buns. You might need a little more or less depending on humidity.
  • Unsalted ButterMelted and cooled butter adds richness, tenderness, and helps create a beautiful crumb structure. Use a plant-based butter for a dairy-free option.
  • SaltEssential for flavor, salt also helps control yeast activity and strengthens the gluten network. Don't skip it!
  • EggOne large egg enriches the dough, contributes to a soft texture, and adds a lovely golden hue to the finished buns.
  • Egg Wash (optional)A whisked egg with a splash of water or milk, brushed on top, gives the buns a beautiful sheen and helps seeds adhere.
  • Sesame Seeds (optional)For that classic burger bun look and a little nutty crunch.

Instructions

  1. Step 1: Activate the Yeast and Mix Wet IngredientsIn the bowl of a stand mixer, combine the warm milk, granulated sugar, active dry yeast, and sourdough discard. Stir gently, then let this mixture sit for 5-10 minutes until it looks slightly foamy. This confirms your yeast is active and ready to work its magic. Add the melted and cooled butter and the large egg to this bubbly mixture, whisking briefly to combine everything. This sets the stage for a rich, flavorful dough.
  2. Step 2: Form the DoughAttach the dough hook to your stand mixer. Gradually add the all-purpose flour and salt to the wet ingredients. Start mixing on low speed until a shaggy dough forms, then increase the speed to medium-low. Continue to knead for 8-10 minutes. The dough should become smooth, elastic, and pull away from the sides of the bowl. If it’s too sticky, add flour a tablespoon at a time; if too dry, add milk a teaspoon at a time. The goal is a supple, pliable dough that springs back when poked.
  3. Step 3: First Rise and DivideLightly oil a large bowl, place the dough inside, and turn it once to coat. Cover the bowl with plastic wrap or a clean kitchen towel. Let the dough rise in a warm place for 1.5 to 2 hours, or until it has doubled in size. This crucial step develops flavor and lightness. Once risen, gently deflate the dough, turn it out onto a lightly floured surface, and divide it into 8 equal pieces. Each piece should weigh approximately 100-110 grams for standard-sized buns.
  4. Step 4: Shape the Buns and Second ProofTake each dough portion and shape it into a tight, round ball. The best technique involves cupping your hand over the dough on the counter and rotating it, applying gentle pressure to create surface tension. Arrange the shaped buns on a baking sheet lined with parchment paper, leaving enough space between them for expansion. Cover the buns loosely with plastic wrap or a towel and let them rise again in a warm spot for another 45-60 minutes, or until they look visibly puffy and light. Preheat your oven to 375°F (190°C) during the last 15 minutes of proofing.
  5. Step 5: Bake to Golden PerfectionJust before baking, gently brush the tops of the proofed buns with an egg wash (if using) and sprinkle with sesame seeds for a classic finish. Bake for 15-20 minutes, or until the buns are deep golden brown and sound hollow when tapped on the bottom. If they're browning too quickly, you can loosely tent them with foil. Allow the buns to cool completely on a wire rack before slicing. Transfer to plates and drizzle with sauce for the perfect finishing touch.

Notes

  • Keep your cooled buns fresh by storing them in an airtight container at room temperature for up to 3 days, or freeze them for longer enjoyment—they thaw beautifully!
  • To bring back that fresh-baked warmth, lightly toast sliced buns, or for whole buns, warm them gently in a 300°F (150°C) oven for 5-7 minutes.
  • Beyond classic hamburgers, these delightfully soft and subtly tangy buns are incredible for pulled chicken, chicken salad sandwiches, or even as a base for a gourmet breakfast sandwich.
  • Achieving that perfect fluffy texture relies on proper kneading; keep going until your dough is smooth, elastic, and springs back readily when gently pressed, which is key for a great crumb.
