Freeze drying cheese opens up a world of culinary possibilities, transforming your favorite varieties like mozzarella and cheddar into shelf-stable ingredients that retain much of their original flavor and nutritional value. Whether you’re a cheese lover looking to extend the life of your cheese or a home cook seeking versatile ingredients that are ready whenever inspiration strikes, freeze drying cheese is a technique worth exploring.

Freeze Drying Cheese at Home

Freeze drying is a preservation method that removes moisture from food through sublimation, turning water directly from ice to vapor under low pressure and temperature conditions. This process retains the food’s structure, nutritional content, and flavor, resulting in lightweight, shelf-stable products that can be rehydrated to their original state with the addition of water. Freeze drying is ideal for extending the shelf life of a wide range of foods, from fruits and vegetables to meats and cheeses, making it a popular choice for long-term food storage and convenient snacking.

Freeze drying cheese at home, be it mozzarella, cheddar, or any other variety, is relatively straightforward with the right equipment.

Preparing Cheese for Freeze Drying

Preparing cheese for freeze drying is a crucial step that influences not only the efficiency of the freeze drying process but also how conveniently you can use the cheese later on. The key is to consider the intended use of the cheese post-freeze drying and to cut it into shapes and sizes that will optimize both drying time and culinary application. Whether you opt for cubes, chunks, slices, or shredded cheese, each form has its benefits for specific uses. Take the time to prepare your cheese before freeze drying; you will optimize the process and ensure that you have the right type of cheese ready for any recipe or use.

Cubes and Chunks

Cubing or chunking cheese is ideal for snacking or for recipes where you might want larger, distinct pieces of cheese that can be quickly rehydrated or eaten as is. Aim for uniform sizes when preparing cheese in cubes or chunks to ensure even freeze drying. This size is perfect for cheese platters, adding to salads, or incorporating into soups where the cheese will melt and impart a rich flavor.

Slices

Slicing cheese is particularly effective for sandwich toppings, cheese boards, or dishes where you’d prefer a layer of cheese, such as on top of casseroles. Thin, even slices freeze dry efficiently and rehydrate well, maintaining much of their original texture and flavor. Ensure slices are consistent in thickness to promote uniform drying.

Shredded

Shredded cheese is exceptionally versatile, ideal for quick melting over dishes, incorporating into sauces, or using as a topping for pizzas and tacos. When shredding cheese for freeze drying, it’s crucial to spread the shreds in a thin, even layer on the freeze-dryer trays to prevent clumping and ensure that each piece dries thoroughly. Remember that commercially shredded cheese often contains anticoagulant agents, which can affect the texture upon rehydration. Shredding your cheese at home allows you to avoid these additives.

Preparing Cheese for Freeze Drying: General Tips

1. Moisture Content: Lower-moisture cheeses tend to freeze dry more effectively. Consider this when choosing which cheeses to preserve.
2. High Fat Content: Higher-fat cheeses may not freeze dry as uniformly as lower-fat varieties due to the way fat behaves under freeze drying conditions. Fat can affect the texture of the freeze dried cheese, potentially making it more crumbly or affecting how it rehydrates.
3. Pre-Freezing: Freezing cheese before placing it in the freeze dryer can help maintain its shape and texture throughout the drying process.
4. Spacing: Whether you’re working with cubes, slices, or shreds, ensure there’s enough space between pieces on the freeze dryer trays to allow for proper air circulation.
5. Think Ahead: Consider how you plan to use the freeze dried cheese. Shredded or thinly sliced cheese may be more practical for recipes requiring quick melting. For snacks or cheese boards, cubes or chunks might be preferable.

Here are the moisture and fat content of popular cheeses:

Cheese	Moisture Content (%)	Fat Content (%)
Cheddar	37	33
Mozzarella (Fresh)	52-60	20-22
Parmesan	30	28
Brie	45-50	20-28
Gouda	41	27-30
Ricotta	72-80	10-13
Feta	55-60	21
Blue Cheese	42	28-30
Swiss Cheese	38	27-31
Cottage Cheese	79-80	4-5

This table highlights the variance in moisture and fat content among different types of cheese, which can influence their freeze drying success, texture, and how they might be used in recipes. ​​

Freeze Drying Process

1. Arrange the cheese in a single layer on the freeze dryer trays, ensuring pieces don’t touch for uniform drying.
2. Run your freeze dryer according to the manufacturer’s instructions. The process usually takes about 24 hours, depending on the moisture content of the cheese.

Packaging Freeze Dried Cheese

Airtight packaging ensures that your freeze dried cheese retains its quality, flavor, and texture. This setup not only extends the shelf life of your cheese but also provides a versatile way to enjoy cheese, whether rehydrated or as a crunchy, no-fuss snack. 

1. Airtight Containers: Use mylar bags with oxygen absorbers or vacuum-sealed bags for the best protection against moisture and air. These materials prevent the reabsorption of moisture, keeping your freeze-dried cheese crisp and fresh.
2. Oxygen Absorbers: Including oxygen absorbers in your packaging is critical to prolonging freeze dried cheese’s shelf life. They help prevent oxidation, which can affect taste and color over time.
3. Portioning: Consider packaging your cheese in portions you’re likely to use in one cooking session. This minimizes the need to open and reseal bags, preserving the quality of the cheese.

Storing Freeze-Dried Cheese

1. Cool, Dark Place: Store your packaged freeze dried cheese in a cool, dark place like a pantry or cupboard. Extreme temperatures and direct sunlight can degrade the quality of the cheese over time.
2. Avoid Humidity: High humidity can lead to moisture seeping into your containers, even if sealed. Using desiccant packets in your storage area can help absorb excess moisture.

Labeling Your Packages

Proper labeling is essential for efficiently identifying and rotating your freeze dried cheese stock. Here’s how to label effectively:

1. Contents and Date: Write the type of cheese and the date of freeze drying on each package. This information helps you keep track of what you have and ensures you use the oldest stock first.
2. Weight or Portions: Note the weight or the number of portions in each package, especially if you’ve divided your cheese into cooking-sized amounts. This makes it easier to choose the right package for your needs without having to open it.
3. Rehydration Instructions: If you have a preferred method for rehydrating that cheese, consider noting this on the package for easy reference.

By meticulously packaging, storing, and labeling your freeze-dried cheese, you extend its shelf life and make your future culinary endeavors more convenient and enjoyable. Whether reaching for a snack or preparing a gourmet meal, your freeze-dried cheese will be ready to enhance your dishes with its preserved flavor and texture.

Enjoying Freeze Dried Cheese Without Rehydration

When cheese is freeze dried, it loses moisture but retains its original taste, transforming into a light, airy, and crunchy snack. This process concentrates the cheese’s flavors, making each bite a more intense experience than its fresh counterpart. Enjoying freeze dried cheese without rehydration is incredibly simple and enjoyable; it can be eaten straight out of the package as a crispy snack, added to trail mixes for a savory kick, or used as a flavorful topping on salads and soups for added texture. The lack of moisture also makes freeze dried cheese a convenient, non-perishable snack, perfect for on-the-go adventures, camping trips, or as an innovative addition to cheese boards at gatherings, offering guests a novel and delicious cheese experience.

Making Freeze Dried Cheese Powder

1. Select Your Cheese: Begin with your preferred type of freeze dried cheese. Both hard and soft cheeses work well, with cheddar, parmesan, and mozzarella being popular for their distinct flavors.
2. Pulverize the Cheese: Break the freeze dried cheese into smaller pieces and place them in a food processor or a high-powered blender. Pulse until the cheese is transformed into a fine powder. Sift the powder through a mesh strainer to remove any larger particles for an even finer consistency.
3. Storage: Store your cheese powder in an airtight container, preferably in a cool, dark place, to preserve its flavor and prevent any moisture absorption. Label the container with the type of cheese and the date it was powdered.

Using Cheese Powder in Recipes

Cheese powder made from freeze dried cheese is incredibly versatile, serving as a flavor booster in a wide range of dishes:

• Biscuits & Quick Breads: Incorporate cheese powder into your dry ingredients to add a cheesy kick to biscuits, scones, and quick bread. The powder evenly distributes the cheese flavor throughout the dough, creating deliciously savory baked goods.
• Macaroni and Cheese: For a quick and easy homemade mac and cheese, whisk cheese powder into your béchamel sauce for a smooth, rich cheese flavor without the clumps that shredded cheese can sometimes produce.
• Cheese Soups & Sauces: Cheese powder dissolves seamlessly into soups and sauces, providing a smooth texture and rich taste. It’s perfect for enhancing everything from a simple cheese sauce to more complex soups like broccoli cheddar.
• Seasoning: Sprinkle cheese powder over popcorn, roasted vegetables, or baked potatoes for an instant flavor upgrade. It can also be mixed into spice blends for an additional depth of flavor.

The Benefits of Cheese Powder

Using freeze dried cheese powder in your cooking and baking elevates the taste of your dishes and offers practical advantages. It’s a convenient way to have cheese on hand without worrying about spoilage, and the powder form allows for easy portion control and quick dissolving. Additionally, making cheese powder from freeze dried cheese at home ensures you know exactly what’s in your food, avoiding the additives and preservatives often found in commercial cheese powders.

Incorporating freeze dried cheese powder into your culinary repertoire is a simple yet impactful way to harness the bold flavors of cheese in a versatile, shelf-stable format. Whether whipping up a family favorite or experimenting with new recipes, cheese powder is a secret ingredient that can transform ordinary dishes into extraordinary creations.

Rehydrating Freeze Dried Cheese

Rehydrating freeze dried cheese is simple but requires a bit of patience to achieve the best texture:

• Place the freeze dried cheese in a bowl and mist it lightly with water, or cover it with a damp paper towel. Allow it to sit at room temperature until it reaches your desired consistency. You may need to experiment to find the perfect rehydration time for your preferences.

Cooking with Rehydrated Cheese

Rehydrated cheese can be used in various recipes, from pizzas and pastas to soups and salads. However, remember that rehydrated cheese may not melt exactly as its fresh counterpart due to the moisture content and texture change. This is particularly noticeable with commercially shredded cheese, where anticoagulants can affect melting and texture. It’s best used in recipes where the cheese is mixed with other ingredients or where perfect meltability is not crucial.
