Tempeh is a versatile and nutritious plant-based protein made from fermented soybeans. With its nutty flavor and firm texture, tempeh has become a popular ingredient in various vegetarian and vegan dishes. If you have a surplus of tempeh or want to stock up for later use, freezing is an excellent way to preserve its freshness and extend its shelf life. By following some simple steps, you can ensure that your tempeh remains flavorful and ready for future culinary creations. This article presents a comprehensive guide on freezing tempeh to maintain its quality and taste.
Here’s a step-by-step guide on how to freeze tempeh:
Step 1: Choose fresh tempeh
Selecting fresh tempeh is crucial when freezing it because the quality of the tempeh at the time of freezing directly impacts its taste and texture when thawed and cooked later. Fresh tempeh that hasn’t surpassed its expiration date is likely to have the best flavor and nutritional value, making it more enjoyable to consume after freezing.
When tempeh is past its prime or close to its expiration date, it may have started to deteriorate, losing some of its original taste and becoming less appetizing. Freezing tempeh in this state could lead to even further degradation in quality, resulting in a less palatable final product.
By checking the packaging or manufacturing date, you can ensure that the tempeh you plan to freeze is at its peak freshness. Ideally, you should freeze tempeh as soon as possible after purchase or as close to the manufacturing date as feasible. This way, you maximize its shelf life and maintain its optimal taste and texture when you decide to use it later.
Step 2: Cut and portion the tempeh
Cutting and portioning the tempeh before freezing serves several practical purposes and enhances its versatility when using it in various recipes.
- Convenient Meal Preparation: By cutting the tempeh into smaller, manageable portions, you can easily grab the amount you need for a particular recipe without having to thaw the entire block. This saves time and effort, especially when you only need a small amount for salads, stir-fries, or sandwiches.
- Faster Thawing: Smaller pieces of tempeh thaw more quickly than a large block, allowing you to cook your dishes without much delay. This is particularly useful when you’re short on time or need to prepare a meal in a hurry.
- Customization: Cutting the tempeh into different shapes, such as slices, cubes, or strips, allows you to tailor it to various dishes. For example, you might prefer slices for pan-frying, cubes for skewers or stews, and strips for sandwiches or wraps. This customization enhances the overall presentation and texture of your dishes.
- Even Cooking: Smaller pieces of tempeh cook more evenly compared to a whole block, ensuring that each portion absorbs the flavors and seasonings consistently.
- Better Marinade Absorption: When tempeh is cut into smaller pieces, it provides more surface area for marinades and seasonings to penetrate, resulting in a more flavorful end product.
- Adaptation to Recipe Needs: Different recipes may call for specific tempeh sizes. For example, a recipe might require small cubes for a soup or large slices for grilling. By portioning the tempeh accordingly, you can easily adapt it to suit various culinary creations.
Step 3: Steam the tempeh
Steaming tempeh before freezing is a simple yet crucial step that can significantly enhance its texture, flavor, and overall quality when it is thawed and cooked later. Here’s why steaming tempeh is beneficial before freezing:
- Texture Improvement: Tempeh can sometimes have a slightly dense or chewy texture, which may not be appealing to everyone. Steaming helps soften the tempeh and gives it a more tender and palatable texture. This is especially important if you plan to use tempeh in dishes where a softer texture is desired, such as in salads or wraps.
- Flavor Enhancement: Steaming tempeh before freezing allows it to absorb some moisture, enhancing its ability to absorb flavors during the cooking process. This results in a more flavorful end product, as the tempeh becomes a blank canvas for various seasonings and marinades.
- Bitterness Reduction: Some batches of tempeh may have a slight bitter taste due to the fermentation process. Steaming helps to reduce this bitterness, making the tempeh taste milder and more enjoyable. This is particularly beneficial for those who are new to tempeh or prefer a less pronounced bitter note.
- Improved Freezing Results: Steaming the tempeh briefly before freezing can help maintain its quality during the freezing and thawing process. The steam slightly opens up the tempeh’s structure, making it easier for moisture to escape during freezing and preventing ice crystals from forming inside the tempeh. This can prevent textural issues that may arise from ice crystal formation.
- Consistent Cooking: Steaming the tempeh ensures that it is partially cooked before freezing, which helps achieve more consistent cooking results when you use it in recipes later. This is especially beneficial when incorporating tempeh into dishes where it needs to be cooked quickly, like stir-fries.
Can I freeze tempeh without steaming it first?
Answer: While it’s recommended to steam tempeh before freezing to improve texture and flavor, you can technically freeze it without steaming. However, steaming helps reduce bitterness and results in a better frozen product.
Step 4: Cool the tempeh
Cooling the tempeh after steaming is a crucial step in the freezing process to maintain its quality and avoid potential issues that can arise from freezing warm or hot tempeh. Here’s why it’s important to cool the tempeh before freezing:
- Preventing Ice Crystal Formation: Freezing warm or hot tempeh directly can lead to the formation of ice crystals within the tempeh. When water molecules inside the tempeh freeze rapidly, they can form sharp ice crystals that damage the cell structure of the tempeh. This can result in a mushy and undesirable texture once the tempeh is thawed and cooked.
- Retaining Texture and Flavor: Cooling the tempeh allows it to firm up slightly, preserving its natural texture and flavor. If tempeh is frozen while still warm, it may become mushy and lose its characteristic nutty and chewy texture. By cooling it down, you can maintain the tempeh’s original texture and ensure a more satisfying culinary experience after freezing.
- Avoiding Bacterial Growth: When tempeh is warm, it provides an ideal environment for bacterial growth. Freezing the tempeh while it’s still warm can trap any existing bacteria inside, which can lead to spoilage or foodborne illnesses when the tempeh is thawed and consumed.
- Preventing Condensation: Cooling the tempeh before freezing also helps to minimize condensation inside the packaging. If warm tempeh is sealed in a container or freezer bag, it can release moisture as it cools down, leading to excess condensation. This can negatively affect the tempeh’s quality and contribute to freezer burn.
To ensure the best results when freezing tempeh, it’s essential to let it cool to room temperature or slightly chill it in the refrigerator before transferring it to the freezer. Once the tempeh is cooled, proceed with arranging it in a single layer on a baking sheet or tray for flash-freezing or placing it in freezer-safe containers for long-term storage.
Step 5: Arrange and flash-freeze the tempeh
To ensure optimal freezing results for your tempeh, it’s essential to follow the proper arrangement and flash-freezing process. By taking these steps, you can maintain the tempeh’s quality, texture, and taste, making it a convenient ingredient for various dishes in the future.
- Arrange the Tempeh for Freezing:
- After steaming and cooling the tempeh, place the individual pieces in a single layer on a baking sheet or tray. Ensure that there is enough space between each piece so they do not touch each other. This arrangement is vital to prevent the tempeh from clumping together during the freezing process.
- When tempeh pieces clump together, they become difficult to separate when you want to use them in recipes. Additionally, frozen tempeh that has clumped may suffer from uneven thawing, affecting its texture and overall quality when cooked.
- Flash-Freeze the Tempeh:
- Once the tempeh pieces are arranged on the baking sheet, transfer the sheet to the coldest part of your freezer. Allow the tempeh to flash-freeze for about two hours or until the pieces are solidly frozen.
- Flash-freezing is a rapid freezing process that helps preserve the tempeh’s original texture and flavor. By freezing the tempeh quickly, it reduces the formation of large ice crystals within the cells, preventing damage to the tempeh’s structure. This ensures that the tempeh maintains its firmness and taste, making it a delightful ingredient to use in a variety of dishes.
- Moreover, flash-freezing prevents the tempeh pieces from sticking together, as they freeze individually before they have a chance to clump. This makes it easier to retrieve the exact amount of tempeh you need for each recipe, without having to thaw the entire batch.
Step 6: Package and seal the tempeh
Packaging and sealing the flash-frozen tempeh in airtight containers or freezer bags is an essential step to protect the tempeh from freezer burn and maintain its quality during long-term storage. Here’s why it’s crucial to package and seal the tempeh properly:

Freezer burn occurs when the surface of frozen food is exposed to air, causing moisture to evaporate and create ice crystals. These ice crystals can lead to the degradation of texture and flavor in the tempeh, resulting in dry and unpleasant spots. By using airtight packaging, you can minimize the contact of the tempeh with air, reducing the risk of freezer burn and preserving its quality.
- Maintaining Freshness and Taste:
When tempeh is not properly sealed, it can absorb odors from other items in the freezer. The porous nature of tempeh makes it more susceptible to taking on unwanted flavors, compromising its taste when used in future recipes. By using airtight packaging, you can ensure that the tempeh retains its original flavors and remains fresh for an extended period.
- Preventing Contamination:
Airtight packaging also helps prevent the tempeh from coming into contact with potential contaminants in the freezer. Proper sealing safeguards the tempeh from cross-contamination with other frozen foods or any airborne particles that may be present in the freezer environment.
- Maximizing Storage Space:
Squeezing out excess air before sealing the packaging not only prevents freezer burn but also helps maximize the available storage space. Removing the air reduces the bulk of the package, allowing you to efficiently organize and stack multiple packages of tempeh in the freezer.
- Easy Portioning:
When the tempeh is packaged in small, airtight portions, it becomes easier to take out only the amount you need for a specific recipe without defrosting the entire package. This makes meal preparation more convenient and efficient.
To package and seal the flash-frozen tempeh, follow these steps:
- Transfer the flash-frozen tempeh pieces into airtight freezer-safe containers or resealable freezer bags.
- Press gently on the containers or bags to remove excess air trapped inside.
- Seal the containers or bags securely to create an airtight seal, ensuring there are no gaps or openings.
- If using resealable bags, consider using the double-bagging method for added protection against freezer burn.

Labeling the packages with the date allows you to identify the oldest packs, and you can prioritize using them before newer ones. This ensures that none of the tempeh goes to waste, and you get the most value from your frozen supply.
- Reducing Food Waste: Without proper labeling, it can be challenging to know how long the tempeh has been in the freezer. As a result, you may unknowingly use older packs after newer ones, leading to potential food waste if the tempeh has surpassed its best quality period.
- Planning Meal Preparation: Knowing the freezing date helps you plan your meal preparation effectively. If you have limited quantities of frozen tempeh left, you can adjust your meal planning accordingly or decide to use it for specific recipes that require less tempeh.
- Ensuring Quality: Properly labeled packages allow you to monitor the tempeh’s freezing duration, helping you consume it while it is still at its best quality. This ensures that the tempeh retains its desired taste, texture, and nutritional value.
To label the packages of frozen tempeh, use freezer-safe labels or waterproof markers. Write the contents (“tempeh”) and the date of freezing on each package or bag. Place the labels in a visible and accessible location, such as the front or top of the package.
Step 8: Store in the freezer
Storing the sealed tempeh packages properly in the freezer is the final step in the freezing process. Proper storage is essential to maintain the tempeh’s quality and ensure it remains safe for consumption over an extended period. Here’s why storing tempeh in the freezer is important:
- Preserving Quality: The freezer acts as a natural preservative, maintaining the tempeh’s texture, flavor, and nutritional value. When stored at freezing temperatures, the tempeh remains in a state of suspended animation, preventing the growth of bacteria, yeast, and mold that could lead to spoilage.
- Extended Shelf Life: When stored correctly, frozen tempeh can maintain its quality for up to six months. The freezing process slows down the degradation of the tempeh, allowing you to enjoy it even when it is out of season or not readily available.
- Preventing Freezer Burn: Placing the sealed tempeh packages away from other items and ensuring they are airtight minimizes the risk of freezer burn. Freezer burn can affect the tempeh’s texture and taste, leading to dry and unpleasant spots. Proper storage protects the tempeh from coming into contact with air and reduces the likelihood of freezer burn.
