These homemade buns repurpose unfed sourdough starter, creating tender, slightly tangy bread that elevates any cookout. The dough comes together with simple pantry staples—milk, butter, egg, and flour—then rises until doubled before shaping into eight perfect-sized logs.

After a second rise, brush with milk and sprinkle with seeds for bakery-style appeal. A final brush of melted butter post-baking ensures an irresistibly soft crust. Dairy-free adaptations and substitution options make this versatile enough for any dietary needs.

My kitchen was already chaos at 7 AM when I decided spur of the moment to make hot dog buns from scratch. I had a jar of sourdough discard staring at me from the fridge and kids asking what was for lunch, so I figured why not try something wild. The house started smelling like yeast and butter within an hour, and suddenly I was the parent who could do magic.

Last summer I made these for a neighborhood barbecue and watched three different people ask where I bought them. Seeing my friend bite into a bun fresh from the oven and immediately ask for the recipe was honestly better than any compliment I could have planned. These buns have a way of making everything else on the plate feel more special.

Ingredients

  • Sourdough discard: The unfed starter gives these buns their signature tang and keeps them incredibly soft
  • Warm milk: Activates the yeast and creates a tender crumb structure
  • Melted butter: Brushing the finished buns makes them pillowy and gives them that bakery sheen
  • Instant yeast: Makes the whole process faster since you do not need to proof it separately
  • All-purpose flour: Bread flour works too but AP gives you that classic hot dog bun texture

Instructions

Wake up the yeast:
Combine warm milk, sugar, and yeast in a large bowl and wait until it gets bubbly and fragrant
Build the dough base:
Stir in the sourdough discard, melted butter, egg, and salt until everything is well incorporated
Bring it together:
Add flour gradually until the dough pulls away from the sides but still feels slightly tacky to the touch
Work the dough:
Knead by hand or stand mixer for about 8 minutes until it feels smooth and springs back when poked
First rise:
Let the dough rest covered in a warm spot until it has doubled in size which takes about an hour
Shape the buns:
Divide into 8 equal pieces and roll each into a 6 inch log, tucking the ends under for smooth tops
Second rise:
Arrange on a parchment lined sheet and let them puff up until they look pillowy and doubled
Bake to golden:
Brush with milk, add seeds if you want, and bake at 375 degrees until deeply golden on top
The finishing touch:
Brush immediately with melted butter while still hot for that soft bakery style crust

These became our go to for everything from sloppy joes to bratwursts, and honestly sometimes we just eat them plain with butter. There is something incredibly satisfying about pulling a warm bun apart and seeing those perfect air pockets you created yourself.

Make Ahead Magic

The dough can sit in the fridge overnight which actually develops more flavor. I have shaped the buns the night before a party and let them do their final rise while the oven preheats the next day.

Freezing For Later

Once baked these freeze beautifully for up to three months. I wrap each bun individually so I can grab exactly what I need without thawing the whole batch.

Customization Ideas

Sometimes I brush them with garlic butter instead of plain butter for an instant garlic bread vibe. Other times I mix herbs into the dough itself for savory buns that stand on their own.

  • Add everything bagel seasoning for a crunchy savory topping
  • Mix shredded cheese into the dough for cheese stuffed buns
  • Brush with honey butter for a sweet twist on the classic

Homemade hot dog buns might seem like extra work but they transform ordinary cookouts into something people will talk about for weeks. Happy baking.

Recipe FAQs

Absolutely. Knead by hand on a lightly floured surface for 7–8 minutes until smooth and elastic. The dough should feel soft and slightly tacky but not sticky.

Thicker discard works fine. You may need slightly less flour to achieve the right dough consistency. Add flour gradually until the dough pulls away from the bowl sides.

Yes, freeze after the first rise. Punch down, wrap tightly, and freeze for up to 3 weeks. Thaw overnight in the refrigerator, then shape and proceed with the second rise.

Brush with an egg wash (beaten egg with 1 tablespoon water) instead of milk before baking. This creates a deeper golden color and glossy finish.

Certainly. Divide the dough into 6–8 pieces, flatten into rounds about 4 inches wide, and follow the same rising and baking instructions.

Ingredients

Dough

  • 1 cup sourdough discard (unfed, 100% hydration)
  • 1 cup warm milk
  • 2 tbsp unsalted butter, melted
  • 2 tbsp sugar
  • 1 large egg
  • 1 ½ tsp salt
  • 3 ¾ – 4 cups all-purpose flour
  • 1 packet instant yeast (7 g or 2 ¼ tsp)

Topping (optional)

  • 1 tbsp milk for brushing
  • 1 tbsp melted butter for brushing after baking
  • Sesame seeds, poppy seeds, or everything seasoning

Instructions

1
Activate the Yeast: Combine warm milk, sugar, and instant yeast in a large mixing bowl. Let the mixture sit for 3–5 minutes until it becomes bubbly and foamy, indicating the yeast is active.
2
Mix Wet Ingredients: Add sourdough discard, melted butter, egg, and salt to the yeast mixture. Stir thoroughly until all wet ingredients are fully incorporated.
3
Form the Dough: Gradually add flour, one cup at a time, mixing continuously. Stop when a soft, tacky dough forms—you may not need the full 4 cups. The dough should hold together without being overly dry.
4
Knead the Dough: Turn the dough onto a lightly floured surface and knead for 7–8 minutes. The dough is ready when smooth, elastic, and springs back when pressed gently.
5
First Rise: Place the dough in a lightly greased bowl, cover with plastic wrap or a clean towel, and let rise in a warm spot until doubled in size, approximately 1–1.5 hours.
6
Shape the Buns: Punch down the risen dough and divide into 8 equal pieces. Roll each piece into a smooth 6-inch log, tapering the ends slightly for an even shape.
7
Second Rise: Arrange the shaped logs on a parchment-lined baking sheet, leaving 2 inches of space between each. Cover and let rise until puffy and noticeably expanded, 30–45 minutes.
8
Preheat Oven: Preheat the oven to 375°F while the buns complete their final rise.
9
Bake the Buns: Brush the buns with milk and sprinkle with seeds if using. Bake for 18–20 minutes until golden brown on top and cooked through.
10
Finish and Cool: Remove from the oven and immediately brush with melted butter for a softer crust. Allow the buns to cool completely on the baking sheet before slicing.
