METHOD 1: OVEN
Placing rolls snugly together in a baking dish leaves the sides of the rolls soft, while separating them and heating on a baking sheet will result in a slightly crisper outside crust.
Arrange a rack in the middle of the oven and heat to 350°F.
Place rolls in a baking dish or arrange on a baking sheet, brush with melted butter and sprinkle with coarse salt, if desired.
Bake until warm, 7 to 10 minutes.
METHOD 2: SLOW COOKER
The slow cooker isn’t the fastest method, taking at least 30 minutes depending on the number of rolls, but it makes them feel more like homemade and frees up your oven for the mains & sides.
Lay a damp, clean kitchen towel on the bottom of the slow cooker insert. Arrange the rolls on the cloth. Cover the top of the slow cooker with a second damp, clean tea towel.
Cover and heat on the LOW setting until warm, about 30 minutes.
After heating, you can turn the slow cooker to the WARM setting and keep the rolls soft and warm until the top towel is dry, about 2 hours.
Do not heat the rolls on HIGH — the edges touching the insert may burn and the rolls will become tough.
METHOD 3: MICROWAVE
Arrange rolls on a microwave-safe plate.
Cover the rolls with a slightly damp, clean kitchen towel.
Wrap the entire plate in a dry tea towel.
Microwave until just warmed through, 30 to 45 seconds.
The rolls should not be piping hot, or they will turn tough and chewy as they cool.
