Sourdough Hot Dog

Summer is finally here, and you know what that means: BBQs, backyard dinners, and hot dogs that deserve so much better than store-bought buns. This sourdough hot dog bun recipe is the one you’ll want to make every weekend until September. Soft, lightly golden, with that subtle depth of flavour only sourdough can bring. And Flora? She’s in her element.

I know what you’re thinking: Sacha, it’s summer, I don’t have time to make bread. But that’s exactly the point — this recipe requires very little hands-on time. You mix everything in the stand mixer, let the fermentation do its thing, and shape in 10 minutes. It’s the ultimate summer bread.

Why This Recipe?

Because store-bought hot dog buns are usually bland white bread — too soft, too sweet, and they fall apart the second they touch the sausage. With sourdough, you get a tight but tender crumb, a lightly golden crust, and a subtle, slightly tangy flavour that pairs perfectly with mustard and all your toppings. Plus, you control exactly what goes in — no additives, no preservatives, just good simple ingredients.
It’s also a great recipe for getting comfortable shaping enriched doughs if you’re just starting out. The dough is soft and easy to work with, and the result is incredibly satisfying.

Role of Each Ingredient

Sourdough Starter (140 g)

The heart of the recipe. It provides the rise, the flavour, and that subtle tanginess that sets these buns apart from any commercial version. Use your starter at its peak — active, bubbly, and doubled — for the best fermentation.

Unbleached All-Purpose Flour (520 g)

All-purpose flour gives a soft, tender crumb — perfect for an enriched bread like hot dog buns. Unbleached, it retains more nutrients and has a more natural flavour. You could swap up to 20% for whole wheat flour for extra depth, but the texture will be slightly denser.

Warm Milk (320 g)

Milk replaces water to enrich the dough and create that soft, pillowy texture characteristic of enriched breads. The fat in the milk tenderizes the gluten network and contributes to a finer, softer crumb. ‘Warm’ means around 35–40°C — warm enough not to shock the starter, but not so hot it kills it.

Unsalted Butter, Softened (30 g)

Butter adds richness, flavour, and helps keep the buns soft longer after baking. ‘Softened’ means room temperature — not melted. Melted butter would change the structure of the dough.

Sugar (30 g)

It lightly feeds the starter, helps with browning during baking (Maillard reaction), and balances the flavour profile. Not enough to make the buns sweet — just enough to make them irresistible.

Salt (9 g)

Salt strengthens the gluten network, controls fermentation, and brings out all the other flavours. Never skip it — bread without salt tastes like cardboard.

Tips

Milk Temperature Matters

Aim for 35–38°C. Too cold, and fermentation will be very slow. Too hot, and you risk slowing down your starter. If you don’t have a thermometer, the milk should feel pleasantly warm to the touch — never hot.

Don’t Skip the Kneading

The 7 to 8 minutes in the stand mixer are essential for gluten development. You’re looking for a smooth, supple, slightly sticky dough that pulls cleanly away from the sides of the bowl. Do the windowpane test (stretch test): the dough should stretch without tearing.

The Fermentation Window Is Wide

5 to 7 hours at room temperature is intentional. On a hot summer day (25°C+), aim for 5 hours. In cooler conditions, let it go up to 7 hours. You’re looking for a dough that has increased in volume by about 50–75% and feels light and airy.

Shaping: Consistency = Even Baking

Divide the dough into equal portions of about 85–90 g each to get 12 buns. Shape each portion into an elongated roll about 12–13 cm long. The more uniform the buns, the more evenly they’ll bake.

Bake Side by Side

Place the buns side by side in a loaf pan or on a baking sheet, just touching each other. This gives them their characteristic rectangular shape and prevents them from spreading.

Egg Wash or Milk Wash?

For a rich, shiny finish: egg yolk mixed with a little milk. For a softer, more matte finish: milk only. Both work perfectly.

Storage

At room temperature: stored in an airtight bag or wrapped in a clean cloth, the buns will keep for 2 to 3 days. They stay soft thanks to the butter and milk.
In the freezer: once completely cooled, freeze in a freezer bag. They’ll keep for up to 3 months. To thaw, leave at room temperature for 1 to 2 hours, or microwave for 20–30 seconds wrapped in a damp cloth.
BBQ tip: freeze in portions of 4 or 6 so you can pull out exactly what you need.
