Plain white, unprinted paper towels and napkins are generally fine for short heating. Recycled, printed or colored paper is the risk, and brown paper bags and newspaper do not belong in a microwave.
Guidance based on USDA material says most paper plates, towels, napkins and bags are microwavable, but for the safest result use white, unprinted paper goods. Recycled paper can contain tiny flecks of metal that spark, and printed or dyed paper can transfer color. Heat for short periods and stay nearby, because dry paper can scorch.

How to use paper in the microwave
- Use a plain white towel or napkin with no print or color.
- Lay it over the dish to catch splatter, or under food to absorb moisture.
- Heat in short bursts and check each time.
- Take it out if it smells scorched or looks brown.
- Never leave the microwave running unwatched with paper in it.
What happens when you get it wrong
- Sparks. Metal flecks in recycled paper can arc and start a fire.
- Scorching. Dry paper heated for too long browns and can catch fire.
- Dye on food. Printed and colored paper can transfer ink or dye.
A microwave safe plate turned over the bowl as a splatter cover.
Parchment paper, which handles the heat better than a paper towel.
