How to Make Sub Rolls at Home
Home sub rolls usually fail in one of two ways: too dense, or crusty all the way through. Both come down to hydration and steam.
Hydration
A wetter dough than feels comfortable is the answer. Around 65% hydration produces the open, soft crumb a sub roll needs. Adding flour until the dough stops sticking is the single most common cause of dense rolls.
Work it with wet hands or a scraper rather than more flour.
Steam
A crisp crust over a soft interior requires steam in the first few minutes of baking. A tray of boiling water on the oven floor, or a few ice cubes thrown in as the rolls go in, both work.
Steam delays crust formation so the roll expands fully before setting — without it the crust hardens early and the inside stays tight.
Shaping and baking
Shape into tight logs rather than loose ones; slack shaping gives flat rolls. Prove until nearly doubled, slash once down the length, and bake hot — around 220°C / 425°F — for 18 to 22 minutes.
Cool on a rack. Cooling on a solid surface traps steam underneath and softens the base you just worked for.
Frequently asked
Why are my rolls dense?
Almost always too much flour, or an under-proved dough. The dough should feel slightly tacky when you stop adding flour.
Can I freeze them?
Yes, once fully cooled. Refresh in a hot oven for five minutes rather than a microwave.
Do I need a stand mixer?
No, though a wet dough is easier with one. By hand, use a scraper and resist adding flour.
