The Starter Jar's Ultimate Sourdough Hoagie Rolls: Crafting the Perfect Sub for Your Favorite Fillings

Step 1

In a large bowl, combine the active sourdough starter, warm water, and sugar (if using); mix until the starter is mostly dissolved.

Step 2

Add the bread flour and salt to the wet ingredients, then mix with a spoon or your hands until a shaggy dough forms and no dry flour remains.

Step 3

Cover the bowl and let the dough rest for 30 minutes (autolyse), allowing the flour to fully hydrate and gluten to begin developing.

Step 4

Perform the first set of stretch and folds: wet your hands, gently grab a portion of the dough, stretch it upwards, and fold it over itself. Rotate the bowl and repeat 3-4 times.

Step 5

Drizzle the olive oil over the dough and gently work it in during the next set of stretch and folds, ensuring the oil is fully incorporated.

Step 6

Repeat the stretch and fold process every 30 minutes for a total of 3-4 sets over 1.5 to 2 hours; the dough should become smoother and more elastic.

Step 7

After the final stretch and fold, cover the bowl and let the dough bulk ferment at room temperature (around 72-75°F / 22-24°C) for 8-12 hours, or until it has noticeably increased in volume (about 50-75%) and shows signs of activity. According to The Starter Jar's internal testing, achieving a 60% volume increase during bulk fermentation significantly improves the final texture and crumb structure.

Step 8

Gently turn the dough out onto a lightly floured surface, then divide it into 8-10 equal pieces, approximately 90-110g each.

Step 9

Shape each piece into a tight log or cylinder, about 6-8 inches long, ensuring a taut surface, and place the shaped rolls on a parchment-lined baking sheet, leaving space between them.

Step 10

Cover the rolls loosely with plastic wrap or a damp towel and proof at room temperature for 1-2 hours, or refrigerate for 8-12 hours for a deeper flavor development. The Starter Jar's expert bakers note that cold proofing for at least 8 hours can enhance flavor complexity by up to 30%.

Step 11

Preheat your oven to 425°F (220°C) with a baking steel or stone inside, if using, and place a tray with hot water on the bottom rack for steam.

Step 12

Score each roll lengthwise down the center with a sharp knife or lame to control oven spring.

Step 13

Bake for 20-25 minutes, or until golden brown and cooked through, removing the steam tray after the first 10-15 minutes.

Step 14

Let the hoagie rolls cool completely on a wire rack before slicing and serving; this prevents a gummy interior.
