Sourdough Discard Hot Dog Buns

The smell of these buns baking takes me back to my first apartment kitchen where I tried turning sourdough discard into everything. My roommate walked in mid-rise asking why I was making hot dog buns from scratch on a Tuesday. By dinner that night she understood completely.

Last summer I made these for a backyard cookout and my brother kept asking what restaurant I bought them from. Watching peoples faces when they realize you baked the buns yourself never gets old. Now they are the only kind I make for barbecue season.

Ingredients

• Sourdough discard: Use unfed starter straight from your fridge for that characteristic tang
• Warm milk: Should feel like bath temperature, around 100 to 105 degrees F
• Melted butter: Adds richness and helps create that soft tender crumb
• Sugar: Feeds the yeast and helps the buns brown beautifully
• Egg: Provides structure and contributes to the pillowy texture
• Salt: Essential for flavor and regulating yeast activity
• All purpose flour: Start with less and add more as needed, humidity affects dough
• Instant yeast: No need to proof separately, it goes right into the warm milk

Instructions

Wake up the yeast:

Combine warm milk and sugar in your large bowl, sprinkle in the yeast and wait 3 to 5 minutes until it looks bubbly and alive

Mix the wet ingredients:

Add your sourdough discard, melted butter, egg and salt to the yeast mixture and stir until everything is incorporated

Build the dough:

Gradually add flour one cup at a time, mixing after each addition until you have a soft tacky dough that holds together

Knead it out:

Turn onto a lightly floured surface and knead for 7 to 8 minutes until the dough feels smooth and elastic

First rise:

Place dough in a greased bowl, cover with plastic wrap or a towel and let rise until doubled, about 1 to 1.5 hours

Shape the buns:

Punch down the dough and divide into 8 equal pieces, roll each into a smooth 6 inch log

Second rise:

Arrange buns on a parchment lined baking sheet 2 inches apart, cover and let rise until puffy, 30 to 45 minutes

Bake golden:

Brush with milk and add seeds if you want, then bake at 375 F for 18 to 20 minutes until deep golden brown

Finish with butter:

Immediately brush hot buns with melted butter for a softer crust and let cool completely before slicing

My daughter now requests these for every birthday dinner even though she is not much of a hot dog person. She just wants the buns toasted with butter. That is when you know a recipe has become part of the family story.

Making Them Ahead

I have shaped the buns the night before and let them do their second rise in the refrigerator. Bring them to room temperature while the oven preheats, they might need an extra 5 minutes in the oven but the convenience is worth it.

Freezing Tips

Once cooled completely these freeze beautifully wrapped tightly in plastic. I double wrap them then thaw on the counter for an hour before refresh in a 350 degree oven for 5 minutes.

Serving Ideas

Beyond classic hot dogs these buns make incredible sandwiches. The slight tang pairs perfectly with pulled pork or even just as garlic bread split and brushed with herb butter.

• Try them for bratwurst with sauerkraut and mustard
• Use day old buns for homemade breadcrumbs or croutons
• They are excellent for sausage and pepper sandwiches

There is something deeply satisfying about turning what would be waste into the best part of the meal. Happy baking.

Questions & Answers

→ What does sourdough discard add to hot dog buns?

Sourdough discard contributes a subtle tangy flavor and helps create a tender, chewy texture. It also adds depth to the overall taste while helping the buns stay fresh longer due to the natural fermentation acids present in the starter.

→ Can I make these buns without a stand mixer?

Absolutely. These buns come together beautifully with hand kneading. Mix ingredients in a large bowl until combined, then turn onto a floured surface and knead for 7-8 minutes until smooth and elastic. The dough is soft and manageable to work with by hand.

→ How do I know when the buns have finished rising?

The first rise is complete when the dough has doubled in size, typically 1-1.5 hours. For the second rise after shaping, the buns are ready when they look puffy and have increased noticeably in volume, about 30-45 minutes. A gentle poke should spring back slowly.

→ Can I freeze these hot dog buns?

Yes, these freeze exceptionally well. Let them cool completely, wrap individually in plastic wrap, then place in a freezer bag for up to 3 months. Thaw at room temperature or warm in a 350°F oven for 5-10 minutes to refresh.

→ What toppings work best on these buns?

Classic toppings like sesame seeds, poppy seeds, or everything bagel seasoning add wonderful texture and flavor. Brush with milk before baking to help seeds adhere. For softer buns, brush with melted butter immediately after removing from the oven.

→ Can I use active sourdough starter instead of discard?

You can use active starter, but reduce the yeast slightly and adjust the flour as needed since active starter has more moisture. The flavor may be slightly more pronounced. The timing for rising might also be faster, so keep an eye on the dough.
