Sourdough Discard Hot Dog Buns

Last summer my sister asked if I could make hot dog buns from scratch, and I honestly laughed it off at first. Why bother when the store sells them by the dozen? But then I remembered my sourdough discard stash taking over the freezer and thought, why not? The first batch came out of the oven golden and impossibly soft, and something about that slight tang from the discard just made everything taste better. Now I can't imagine going back to the bagged ones.

I made these for a Memorial Day cookout last year, and my brother-in-law actually asked where I bought them. When I told him they were homemade, he looked genuinely shocked. Theres something so satisfying about serving food that makes people do a double-take like that.

Ingredients

• Sourdough discard: Use unfed starter at 100% hydration for that subtle tang and extra moisture that keeps buns fresh longer
• Warm milk: Should feel like bath temperature to activate your yeast without killing it
• Melted butter: Creates the softest texture possible and adds richness to the crumb
• Sugar: Feeds the yeast and helps the buns develop that gorgeous golden-brown color
• Egg: Adds structure and gives the dough extra tenderness
• Salt: Essential for flavor and helps strengthen the gluten network
• All-purpose flour: Start with less and add gradually until you reach the right consistency
• Instant yeast: No need to proof separately, just mix right in
• Milk for brushing: Creates a sticky surface for seeds to adhere to
• Melted butter for finishing: Brushing warm buns keeps the crust soft and inviting

Instructions

Wake up the yeast:

Combine the warm milk with sugar and yeast in your largest mixing bowl, letting it bubble for 3 to 5 minutes until foamy and alive

Build the base:

Stir in the sourdough discard, melted butter, egg, and salt until everything is evenly incorporated

Bring it together:

Add flour one cup at a time, mixing after each addition until a soft, slightly tacky dough forms

Knead to perfection:

Work the dough on a lightly floured surface for 7 to 8 minutes until smooth, elastic, and springy

Let it rise:

Place the dough in a greased bowl, cover, and let double in size for about 1 to 1.5 hours

Shape the buns:

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

Second rise:

Arrange buns on a parchment-lined sheet 2 inches apart, cover, and let puff up for 30 to 45 minutes

Preheat and prep:

Heat your oven to 375°F and brush the risen buns with milk

Add the toppings:

Sprinkle with sesame seeds, poppy seeds, or everything seasoning if you want that bakery finish

Bake to golden:

Bake for 18 to 20 minutes until deeply golden and they sound hollow when tapped

Finish with butter:

Brush warm buns immediately with melted butter for the softest crust imaginable

Save

My daughter helped shape the buns last time, and hers turned out beautifully imperfect in the best way. Theres such joy in passing down these little kitchen moments.

Getting the Shape Just Right

I used to roll my buns too thin, and they'd bake up like little sticks instead of pillowy clouds. The secret is rolling them between your palms with gentle pressure, letting the dough relax into a log shape naturally. If it springs back, let it rest for a minute and try again.

Making Them Ahead

You can shape these buns, place them on your baking sheet, and refrigerate overnight for the final rise. Just take them out while the oven preheats, and they'll puff up beautifully as they come to room temperature. This has saved me so many times when hosting.

Storage and Freezing

These stay surprisingly fresh at room temperature for two days when stored in a paper bag. For longer storage, freeze them in a ziplock bag and thaw on the counter for an hour before serving.

• Slice before freezing and toast straight from frozen for the best results
• Wrap frozen buns in foil and reheat at 350°F for 10 minutes to refresh them
• Never store in plastic bags or they'll get soggy and lose that perfect crust

Theres something profoundly satisfying about baking something people usually take for granted. Once you taste these, store-bought buns just won't hit the same way.

Recipe FAQs

→ Can I make these without a stand mixer?

Absolutely. Knead by hand on a lightly floured surface for 7–8 minutes until the dough feels smooth and elastic. The process is quite therapeutic and yields excellent results.

→ How should I store these buns?

Keep in an airtight bag at room temperature for 2–3 days. For longer storage, freeze individually wrapped buns for up to 3 months. Thaw at room temperature before serving.

→ What if my sourdough discard is very thick or thin?

Adjust flour accordingly. Thinner discard may need an extra ¼–½ cup flour, while thicker discard might require slightly less. Aim for a soft, tacky dough that holds together without being sticky.

→ Can I prepare the dough ahead of time?

Yes. After the first rise, punch down the dough and refrigerate overnight (up to 18 hours). Bring to room temperature for about 30 minutes before shaping and proceeding with the second rise.

→ What's the best way to reheat these buns?

Wrap in foil and warm in a 350°F oven for 5–7 minutes, or split and toast cut-side up under a broiler for 1–2 minutes. For soft results, microwave wrapped in a damp paper towel for 15–20 seconds.

→ Can I use this dough for hamburger buns?

Certainly. Divide the dough into 6–8 pieces instead of 8 and flatten into rounds about 4 inches wide. Follow the same rising and baking instructions, adjusting time as needed until golden.
