You can put dinner rolls in the microwave and heat them for 10 to 15 seconds but you should spray a bit of water on them to keep the dinner rolls moist and prevent them from drying out.
Heating a dinner roll in the microwave takes between 10 to 15 seconds.
Place the dinner roll in the microwave after spraying it with a bit of water to keep it moist and start the microwave for 10 seconds and check it and if still not warm enough eat for another 15 seconds until warm enough.
To soften hard rolls in the microwave moisten a section of paper towel long enough to cover the hard roll and then wrap the hard roll in the damp paper towel.
Then place the wrapped roll in the microwave for 10 seconds to soften it.
You can also soften hard rolls by wrapping the hard rolls in a damp paper towel and then placing some aluminum foil over them to wrap them to hold the moisture in or run a bit of water over the hard rolls and wrap them in aluminum foil and heat them in an oven at 300 F for 12 to 15 minutes.
A toaster oven also works well for heating and softening hard rolls.
If you don't have an oven or toaster oven you can moisten a section of paper towel long enough to cover the hard rolls and then wrap the hard rolls in the damp paper towel.
Then place the wrapped hard rolls in the microwave for 10 seconds to soften them.
You can also soften hard bread by wrapping the bread in a damp towel and placing the bread on a baking sheet with the damp towel.
Then heat it in the oven for 5 to 10 minutes or wrap the bread in a damp towel and place the bread on a microwave safe dish or plate and microwave on high for 10 seconds.
The best place to store bread in the kitchen is in a cool dry area of the kitchen away from any moisture.
You could store the bread in a kitchen cabinet away from moisture or in a deep drawer.
Another option is to store the bread in the microwave when not using it or a bread box.
If eating the bread within a few days you can simply store the bread right on the counter in the open and it will be fine for the few days.
In general, most loaves of bread will last up to a week at room temperature, and 3 to 5 days longer in the fridge—though keep in mind that refrigeration of the bread can make the bread go stale.
Bread that goes stale is still useful for breadcrumbs, croutons, and bread pudding.
Using an airtight container will preserve the moisture in the bread and keep it from drying out too quickly.
However too much moisture can lead to the bread molding.
If part of the bread is moldy you can remove the moldy parts of the bread and eat the rest which is what I do.
A freezer bag is also a decent short-term, room-temperature bread storage solution.
Storing the bread on the countertop in a plastic bag (or well-sealed plastic wrap) will help keep it from going stale, but be warned the crust of the bread will suffer and grow mold due to trapped moisture.
