# Can you microwave McDonald's containers?

**No: No — the cartons, wrappers and cups are not made for reheating, and some have foil layers.**

Burger cartons and fry boxes are paperboard with a thin coating, sized for a single hot meal and nothing more. Some sandwich wrappers are foil-laminated, which arcs. Cups are wax or plastic-lined paper with a plastic lid that softens well below the temperature you would want the drink at. None of these carry a microwave-safe mark because none were tested for that use. The food inside reheats perfectly well once it is on a plate.

## What goes wrong

- Foil-laminated wrappers spark
- Coated board and cup linings soften and can transfer to the food
- Plastic lids warp and can seal, then release a burst of steam

## What to do instead

- Put the burger on a plate, remove the lettuce first, and reheat for 30-45 seconds
- Reheat fries in an air fryer or a dry frying pan; a microwave makes them limp
