The Simple Way To Keep Dinner Rolls Warm After They Leave The Oven - Tasting Table
Briefly

To keep freshly baked dinner rolls warm, fill a clean paper bag with uncooked rice, heat it in the microwave, and use it as an insulated base.
This method not only maintains the warmth of your rolls but also ensures they stay dry and soft, preventing any sogginess from trapped moisture.
For a classic solution, mimic restaurant practices by wrapping bread in a towel-lined basket, which helps contain heat and keeps the bread warm.
A more lasting solution is a bread-warming basket with a terracotta stone, retaining and radiating heat while preventing moisture buildup.
