Marshmallows have long been a beloved treat, finding their way into our favorite hot cocoa mugs, s’mores by the campfire, and even cereal bowls. But have you ever wondered if you can freeze-dry marshmallows?

The idea of freeze-drying these fluffy confections might pique your curiosity, and this article aims to explore the ins and outs of this sugary adventure.

In this comprehensive guide, we’ll delve into the world of freeze dry marshmallows, covering everything from the process of freeze drying to the advantages and disadvantages of enjoying these sweet morsels in their freeze-dried form. So, if you’re a marshmallow enthusiast or just someone with a sweet tooth, read on to satisfy your curiosity.

What is Freeze Drying?

Before we dive into the main question, let’s briefly explore what freeze drying is. Freeze drying, also known as lyophilization, is a preservation technique that involves removing moisture from a substance while keeping its structure and flavor intact.
It’s commonly used for various foods, pharmaceuticals, and even in the preservation of historical documents.

Can You Freeze Dry Marshmallows?

Now, let’s address the burning question: Can you freeze-dry marshmallows? The answer is a resounding yes! Marshmallows, with their high sugar content and airy texture, are well-suited for the freeze-drying process.

During freeze-drying, marshmallows undergo a transformation that removes their moisture content while preserving their shape and flavor. The result is a crunchy and lightweight version of the original marshmallow, making them perfect for a variety of culinary applications.

The Process of Freeze Drying Marshmallows

The process of freeze drying marshmallows is a fascinating journey that transforms these sugary confections into crunchy, lightweight morsels while preserving their flavor. Here’s a step by step look at how it’s done:


The first step in freeze drying marshmallows involves preparing them for the freezing process. Marshmallows are typically composed of sugar, corn syrup, gelatin, and water, which give them their soft and fluffy texture.

To freeze dry them, they are often sorted and selected for uniformity in size and shape.


Once sorted, the marshmallows are placed in a freezer and rapidly frozen to a very low temperature. This freezing step is crucial because it sets the stage for the subsequent sublimation process.

Freezing the marshmallows solidifies the water content within them, preparing them for the removal of moisture without causing them to collapse.

Vacuum Chamber

After freezing, the marshmallows are transferred to a vacuum chamber. This chamber is a sealed environment where the air pressure is significantly reduced. The low pressure encourages the frozen water within the marshmallows to transition directly from ice to vapor, bypassing the liquid phase. This process is called sublimation.


Gradually, the temperature inside the vacuum chamber is raised. This controlled increase in temperature helps facilitate the sublimation process, ensuring that the marshmallows lose moisture without melting or becoming overly sticky.

The water vapor is then removed from the chamber, leaving behind the freeze-dried marshmallows.


The final step involves packaging the freeze dried marshmallows to protect them from moisture and environmental factors that could affect their quality. They are often sealed in airtight containers or bags to maintain their crunchiness and flavor.

The result of this intricate process is freeze dried marshmallows that retain their shape and flavor but have a crunchy texture and are nearly devoid of moisture.

These freeze-dried marshmallows can be enjoyed in various ways, from snacking straight out of the bag to adding them as a topping or ingredient in a wide range of culinary creations.

Advantages of Freeze-Dried Marshmallows

1. Extended Shelf Life

One of the significant advantages of freeze-dried marshmallows is their extended shelf life. Traditional marshmallows can become stale and hard over time, but their freeze-dried counterparts can last for months or even years when stored properly. This makes them an excellent choice for long-term storage or for creating homemade snack mixes and desserts.

2. Lightweight and Easy to Store

Freeze-dried marshmallows are incredibly lightweight, which makes them convenient for backpacking, camping trips, or as a crunchy topping for your favorite desserts. Their reduced weight makes them easy to carry and store without adding extra bulk to your supplies.

3. Versatile Usage

These freeze-dried delights are incredibly versatile in the kitchen. Whether you want to use them as a topping for ice cream, yogurt, or cereal, or as an ingredient in cookies, brownies, or trail mix, freeze-dried marshmallows can add a delightful crunch and sweetness to a wide range of dishes.

Disadvantages of Freeze-Dried Marshmallows

1. Texture Changes

While freeze-dried marshmallows offer a unique crunch, some people may miss the chewy, gooey texture of traditional marshmallows. The freeze-drying process alters their texture, making them more brittle and less chewy, which can be a drawback for those who enjoy the original marshmallow experience.

2. Cost

Freeze-dried marshmallows can be more expensive than their traditional counterparts. The freeze-drying process requires specialized equipment and can be time-consuming, contributing to a higher price point. If you’re on a tight budget, this might be a factor to consider when purchasing them.

Do Freeze Dried Marshmallows Puff Up?

One common question about freeze-dried marshmallows is whether they puff up like regular marshmallows when exposed to heat. The answer is no.

Freeze dried marshmallows do not puff up when heated because they lack the moisture content necessary for the characteristic expansion of marshmallows when exposed to heat.

When you place freeze-dried marshmallows in hot cocoa or on a baking sheet for cookies, they will maintain their crunchy texture and size. While they won’t provide the gooey, expanding experience of traditional marshmallows, their crunchiness can still be a delightful addition to your favorite recipes.

How Do You Make Freeze Dried Marshmallows?

If you’re feeling adventurous and want to try making freeze-dried marshmallows at home, here’s a simplified version of the process:


  • Marshmallows


  • A freezer
  • A vacuum chamber
  • A freeze-drying machine


  1. Prepare the Marshmallows: Start by selecting the marshmallows you want to freeze-dry. Ensure they are uniform in size and shape for consistent results.
  2. Freeze: Place the marshmallows in a freezer and let them freeze completely. This step is crucial for setting the stage for the sublimation process.
  3. Transfer to Vacuum Chamber: Move the frozen marshmallows to a vacuum chamber. Ensure the chamber is properly sealed and maintained at a low pressure.
  4. Sublimation: Gradually increase the temperature inside the vacuum chamber. As the frozen water within the marshmallows turns to vapor and is removed, you’ll be left with freeze-dried marshmallows.
  5. Packaging: Once the process is complete, transfer the freeze-dried marshmallows to airtight containers or bags for storage.

Please note that home freeze-drying may not achieve the same level of quality and consistency as commercial equipment, so results may vary.
