Pro Tips/Recipe Notes
- When you’re dehydrating marshmallows they will puff and “round” themselves out until they look like those horrible pillow mints that were given out at every single 1980s wedding.
- No dehydrator? Place marshmallows on rimmed baking sheets lined with parchment and place in the oven at the lowest temperature possible (usually 140-170˚F) and prop open the door with the handle of a wooden spoon. This allows condensation to escape instead of just settling back onto the marshmallows. Bake for 5-8 hours, checking every hour and rotating trays.
- Keep them at room temperature in an air-tight container like a mason jar. You’ll want to make sure the marshmallows are fully dried and cooled before putting the lid on the container.
Dehydrated Marshmallows Recipe
Equipment
Ingredients
- 10 oz bag mini marshmallows
Instructions
- Arrange marshmallows on 1-3 dehydrator trays.10 oz bag mini marshmallows
- Spread them out on the trays but don't worry too much about them touching.
- Set the dehydrator to 135˚F (57˚c).
- Dry for 6-10 hours, rotating trays if you think about it. Move marshmallows around on the trays as they become drier to avoid them sticking together.
- They're ready when they crumble when you try to squish them between your fingers and they don't "give" when squeezed
Notes
- If you have larger marshmallows, you can cut them into smaller pieces with kitchen shears. Dust with a bit of homemade powdered sugar to keep them from sticking together. Or dry them whole for 24 hours.
- The marshmallows will continue to dry a bit as they cool, so do your final test on fully-cooled marshmallows. You can’t over-dry them.

I haven’t tried it, but I don’t see why not. You can basically dehydrate anything!
