Sourdough with Sandy: Sourdough Burger Buns

Sourdough RollsWhen Memorial Day kicks off summer on the Outer Banks, then we’re kicking it off the best way we know how—with a homemade sourdough burger bun.

These buns are soft, golden, flavorful, and have just the right touch of sourdough tang to make your cookout feel a little more homemade and a whole lot more special.

We’ve been having fun experimenting with our starter (who’s hanging on strong, by the way!), and this recipe is quickly becoming a favorite. It’s simple enough for beginners but feels like such a fun accomplishment when you take that first bite of a burger stacked on a bun you made from scratch.

Why We Love These Buns

  • Soft & pillowy: Light and airy inside with just enough structure.
  • Flavorful: The sourdough adds a depth that store-bought buns just can’t match.
  • Customizable: Make them larger for big burgers or smaller for sliders.
  • Prep ahead: Let them rise overnight and bake fresh the next day.

Ingredients

  • 1 cup active sourdough starter (fed and bubbly)
  • 3 ½ cups all-purpose flour (or bread flour for a chewier texture)
  • 1 cup warm milk
  • 2 tablespoons butter (softened)
  • 2 tablespoons honey or sugar
  • 1 egg (for the dough)
  • 1 ½ teaspoons salt
  • 1 egg + 1 tablespoon water (for egg wash)
  • Optional: sesame seeds, poppy seeds, or everything bagel topping

Instructions

  1. Mix the dough

In a stand mixer or large bowl, combine the starter, milk, butter, honey, egg, and salt. Mix in flour 1 cup at a time until a soft dough forms.

Knead by hand or with a dough hook for 5–8 minutes, until smooth and elastic.

  1. Bulk ferment

Cover and let the dough rise at room temperature for 4–6 hours, or until roughly doubled in size. (Ideally, cover and place in the fridge overnight.)

  1. Shape the buns

Divide dough into 8 equal pieces. Shape into smooth balls and place on a parchment-lined baking sheet, leaving space between each. Gently press them down to flatten slightly.

  1. Final rise

Cover loosely and let rise again for 1–2 hours, until puffy.

  1. Bake

Preheat oven to 375°F. Brush tops with egg wash and sprinkle with your toppings of choice. Bake for 18–22 minutes or until golden brown.

Let cool completely before slicing.

Tips

  • These buns pair perfectly with burgers or High Cotton pork BBQ.
  • Make sure your starter is extra bubby! Ours wasn’t the first time we made them and the buns turned out a little denser than we would have liked.
  • Our sizes didn’t come out very uniform. We had a couple that looked like sliders, a few regulars, and then some jumbo buns! So if you’re wanting them all to be the same size, pay more attention than we did when shaping them.
