Marshmallows, a sort of confectionery curated from gelatin and sugar, are generally prepared and consumed directly. This low-calorie candy substitute will always satisfy your sweet tooth.

If you’re in search of ways to recreate the famous Lucky Charms marshmallow cereal, you should consider dehydrating your marshmallows.

But, there is a multitude of ways for doing so; which is the best?

We have included hours of research and experience in developing five simple ways for dehydrating marshmallows.

How to Dehydrate Marshmallows Using a Food Dehydrator

Time needed: 1 day.

Dehydrating marshmallows with a food dehydrator will save you the time for checking up on your marshmallows constantly. You’d have fewer chances of your marshmallows ending up burnt.

Optimum temperature: 150 degrees Fahrenheit or 62 degrees Celsius.

  1. What will you need?

    1. Dehydrating racks
    2. A pair of scissors or a knife
    3. Wet cloth
    4. Powdered sugar

  2. Cut down Large Marshmallows

    Although mini marshmallows can go on the dehydrating racks, larger marshmallows should be cut down. It simply accelerates the drying process.

    You may use scissors or a knife, but for a recommendation, carry a wet cloth with you to clean the blades on a regular basis.

    It also helps to have a confectioner’s sugar (powdered sugar) on hand to dust your scissors or knife.

    The larger-shaped marshmallows would lose their shape due to this so that it could save you hours of drying time.

  3. Separate the Marshmallows

    Make an effort to separate your marshmallows so that they don’t bind together and dry inefficiently.

    Since marshmallows jump around, don’t be concerned about them staying put during the dehydrating process.

    One Excalibur Dehydrator tray can comfortably accommodate half a bag of mini marshmallows, with plenty of breathing space.

  4. Dehydrate the Marshmallows

    Set the dehydrator to 150 degrees Fahrenheit. The amount of time needed depends on the size of your marshmallows and the humidity level at your place.

    This also depends on the power of your dehydrator. Minis can take anywhere from 4 to 12 hours to complete. Large dehydrators can take anywhere from 10 to 24 hours.

    Keep in mind that you can’t let them dry for too long. The longer they sit on the trays, the more thoroughly dried they will be.

Dehydrate Marshmallows Using an Oven

Time taken: About 10 to 12 hours

Optimum temperature: 170 degrees Fahrenheit.

Place them in the Oven

Heat on the lowest setting for an hour, then open the oven slightly to allow them to cool to room temperature.

Heat for another hour at the lowest temperature with the door slightly ajar. Overheating marshmallows can cause them to turn brown or black and become crunchy.

Set them to Cool

Remove the baking sheet from the oven and set it to cool as the marshmallows harden.

You can chill them to fasten the cooling and hardening process. It’ll take about 10 – 12 hours to dry the marshmallows completely.

Dehydrate Marshmallows Using a Microwave

Time taken: An hour or two

What will you need?

  • A pair of scissors or a knife
  • Powdered sugar

Place them in the microwave – Heat the marshmallows on high for 60 to 90 seconds in the microwave. You will be able to see the marshmallows expand in size during this.

Heat for an hour on the lowest level, then open the microwave slightly for another hour at the lowest temperature.

If using miniature marshmallows, reduce the microwave time to 30 to 45 seconds. Microwaving marshmallows too long will turn them brown or black and make them crunchy.

Let them Cool

Enable the marshmallows to cool for five minutes after removing them from the microwave. They will harden and shrink back to their original size during this time.

Dehydrate Marshmallows Using an Air Fryer

Time taken: About 2 to 3 hours

Optimum temperature: 160 degrees Fahrenheit

Using an air fryer to dehydrate your marshmallows is a safe alternative to other methods.

You can instantly dry a handful of marshmallows without worrying about them overheating.

Half the Large Marshmallows

Larger marshmallows should be cut into halves. They can dehydrate much quicker if they are cut into smaller pieces.

You can utilize a pair of scissors or make use of a sharp knife. It is recommended to carry a wet cloth along to clean the blades constantly during this process.

You can learn how this is fine from here:

 

Defrost the marshmallows in the machine until they are dehydrated. If not, choose a longer drying time.

The marshmallows will expand in size after being freeze-dried.

Assorted Marshmallows vs. Plain Marshmallows – The Right Marshmallow to Dehydrate

Colored marshmallows are usually inferior to regular marshmallows due to their flavor or color.

This causes the formation of the dried marshmallow to be disfigured, whereas plain marshmallows retain their shape after drying.

Knowing When Marshmallows are Dehydrated Properly

You will have to pick any random marshmallow from the bunch and squeeze it lightly. They are fully dehydrated if they have hardened up and don’t feel soft.

However, if the marshmallows are still slightly soft and give in when squeezed, you need to dry them for a longer duration.

The Perfect Marshmallows Size to Dehydrate

Any size marshmallow will suffice! Larger marshmallows can simply take longer to dehydrate completely.

Smaller mini marshmallows, on the other hand, would be quicker. Go for medium marshmallows if you can’t decide on which one to pick.

The Right Way to Store Dehydrated Marshmallows

Place the marshmallows in an airtight container to keep them fresh. Your marshmallows can be preserved in this manner for months if properly stored.

You can also stretch the shelf-life much further if you have a vacuum seal device. Vacuum-seal marshmallows to keep them fresh for up to a year.

Continue drying for a few more hours if any moisture remains inside the jar after 24 hours.

Our Take on which Method is Best

Dying your marshmallows in an air fryer is the best option if you are looking for something safe and don’t have to worry about them burning.

However, air fryers are only limited to a handful of marshmallows, so go for food dehydrators, ovens, and microwaves.

There are chances of your marshmallows getting overheated and turning completely black, so keep a constant watch on them when using these three methods.

Freeze drying marshmallows is also a convenient way to dehydrate them in bulk, but it will consume a lot of time.

FAQs

How do you know when the dehydrated marshmallows are done?

When dehydrated, marshmallows are crunchy and crumble when biting or crushing them in your hands, and they are ready.

Before you test them, allow them to come to room temperature. Because they are still warm, they will stay a little soft. Some of them, like peppermint marshmallows, may even puff up a little.

Will marshmallows shrink or expand on dehydrating?

My marshmallows stayed pretty much the same size. Now, depending on the brand you purchased, you can get a different result.

When completely dried, the marshmallows will usually remain nearly the same size. It may also expand.

Is it possible to dehydrate marshmallows left from an open bag?

Try to lower your microwave’s time to just 30 to 45 seconds if using miniature marshmallows.

The oven-hot air approach does not alter the times. Fill an open bag of marshmallows.

Place them in a cool, quiet, and dry location, such as the pantry.
