These sweet potato sourdough rolls are the kind of recipe that quietly becomes a staple. They bake up soft and fluffy with a lightly sweet crumb and beautiful golden tops. Mashed sweet potato adds moisture and natural sweetness, while active sourdough starter brings depth without making the rolls overly tangy. The overnight refrigerator fermentation makes the dough easier to handle and lets you bake fresh rolls the next day. This is a practical make-ahead roll recipe for weeknight dinners, holiday meals, or warm-with-butter snacking.Best part? You can mix the dough the night before and bake fresh rolls the next day.

Ingredient Notes (Milk vs Water vs Kefir)

LiquidFlavor Result
MilkSoft, rich, classic
WaterMore neutral, slightly lighter
Water kefirSlight tang, deeper flavor

Instructions

Step 1: Mix the Dough (Night Before)

In a large bowl or stand mixer, combine:

  • flour
  • milk (or water kefir or water)
  • mashed sweet potato
  • sourdough starter

Mix until combined and let rest for 30 minutes (autolyse). Add:

  • honey or maple syrup
  • salt
  • softened butter

Knead until smooth and elastic (about 6–8 minutes).

Step 2: Bulk Fermentation

  • Cover and let rest at room temperature for 1 hour
  • Transfer to the refrigerator and ferment overnight

This slow fermentation builds flavor and improves texture.

Step 3: Shape the Rolls (Next Morning)

  • Remove dough from refrigerator
  • Let sit at room temperature for 45–60 minutes

Divide into 12 equal pieces (~85 g each).

Final Proof

Let the rolls rise until soft and puffy. Time:

  • Room temp: 2–3 hours
  • Proof setting (optional): faster at ~75–80°F

What Properly Proofed Rolls Look Like You’re looking for: ✔ noticeably puffed and expanded ✔ dough feels light and airy ✔ rolls are beginning to touch ✔ poke test: dent slowly springs back

  • If it springs back quickly → needs more time
  • If it stays indented → slightly overproofed

Bake

Preheat oven to 375°F Bake for 18–22 minutes, until golden brown

Timing Example (Real-Life Schedule)

Night Before

  • 7:00 pm – mix dough
  • 7:30 pm – knead
  • 8:30 pm – rest complete

Tips for Success

  • Use smooth, well-mashed sweet potato (no chunks)

  • Don’t skip the overnight rest—it improves both flavor and texture
  • Milk gives the most browning, while water kefir adds tang and fermentation benefits
