Do I Have to Refrigerate Tempeh?
Storing Your Soy-Based Protein Properly
When it comes to storing tempeh, a fermented soy product beloved for its rich nutty flavor and versatility, refrigeration is indeed important. As a result of the fermentation process, tempeh possesses a unique set of storage requirements to maintain its quality and safety. Typically, store-bought tempeh has been pasteurized, halting fermentation and making refrigeration necessary to prevent spoilage and maintain freshness.
The preservation of tempeh in the refrigerator is crucial to slow down any residual fermentation that may continue even after pasteurization. The cool temperatures in a refrigerator are effective in extending tempeh's shelf life while keeping its taste and texture intact. For both opened and unopened packages, ensuring that tempeh is kept in an airtight container or sealed in plastic wrap is recommendable to guard against moisture loss and protect it from other odors or flavors that may be present in the fridge.
While tempeh is quite durable when refrigerated, consumers should heed the advice on storage to optimize the product's longevity and quality. After opening, tempeh should ideally be used within a few days, although unused portions can be stored properly in the fridge to slightly extend this window. Despite its fermented nature, tempeh's storage is not overly complex, but careful attention to these details assures that its full flavors can be enjoyed in a variety of culinary applications.
Understanding Tempeh
Tempeh is a traditional soy product originating from Indonesia and is lauded for its high nutritional value. Particularly valued as a source of protein, tempeh also delivers essential nutrients in a plant-based form.

The cultural significance of tempeh in Indonesian cuisine is notable, as it is both a traditional and a contemporary food used in various dishes. Made from fermented soybeans, tempeh retains a firm texture and has an umami flavor that adapts well to numerous cooking methods.
Nutritional Profile
One serving of tempeh (approximately 100 grams) typically contains:
Protein: 19 grams, which is vital for muscle repair and enzymatic functions.
Fiber: A good source of dietary fiber, important for digestive health.
Minerals:
Iron: About 2.7 mg, instrumental in oxygen transport and metabolism.
Calcium: Roughly 111 mg, crucial for bone health.
Potassium: Around 412 mg, necessary for cardiovascular and muscle function.
In addition to these nutrients, tempeh is a whole food rich in various other vitamins and minerals. Given that it is made through fermentation, it also offers some health benefits associated with fermented foods, such as potentially having a beneficial impact on gut health.
Storing Tempeh
When storing tempeh, it is critical to consider whether the product is pasteurized and to use proper containers. This ensures both safety and longevity for this plant-based protein source.
Refrigeration Requirements
Tempeh should be stored in the refrigerator to maintain its freshness. The ideal storage temperature is below 40°F (4°C). It is important to store tempeh in an airtight container, as this helps to slow down any residual fermentation processes and prevent contamination. For pasteurized tempeh, which is most commonly found in stores, this step also halts further fermentation.
Temperature: Maintain a fridge temperature below 40°F (4°C).
Packaging: Store in an airtight container or wrapped in parchment or wax paper.
Freezer Storage
For longer-term storage, tempeh can be kept in the freezer. To freeze tempeh effectively:
Dry the tempeh thoroughly.
Slice or cube the tempeh if preferred.
Arrange it in a single layer on a baking sheet and freeze for 1-3 hours.
Transfer it to an airtight container or sealed freezer bag, ensuring all air is expelled.
Label the container with the date to keep track of its shelf life.
When one wishes to thaw frozen tempeh, they should transfer it to the refrigerator and let it slowly defrost to maintain its texture and flavor. It is not recommended to thaw tempeh at room temperature as it can lead to uneven defrosting and potential bacterial growth.
Preparing Tempeh
Preparing tempeh properly can enhance its flavor and texture, making it a versatile ingredient in many dishes. From simple steaming to more elaborate marinating and cooking techniques, there are methods suitable for novice cooks and seasoned chefs alike.
Basic Preparation Techniques
Before cooking, one should cut the tempeh into the desired shape—cubes, strips, or slices. For a basic preparation, steaming tempeh for about 10 minutes helps remove its natural bitterness and makes it more receptive to flavors. A simple method is to:
Cut the tempeh into slices or chunks.
Steam over boiling water using a steamer basket for 10 minutes.
Marinate (optional) the steamed tempeh in a mixture of sauces and spices for at least 20 minutes to infuse it with flavors.
Advanced Cooking Methods
Once tempeh is marinated or even plain, there are several cooking methods to consider:
Baking:
Preheat the oven to 350°F (175°C).
Arrange marinated or seasoned tempeh on a lined baking sheet.
Bake for 15-20 minutes or until golden brown and crispy.
Frying:
Heat oil in a non-stick frying pan over medium heat.
Add the tempeh without overcrowding and fry until each side is golden brown, usually about 3-5 minutes per side.
Grilling:
Preheat the grill to a medium-high setting.
Lightly oil the grill grate to prevent sticking.
Grill tempeh until it has grill marks and is heated through, typically 2-3 minutes per side.
Equipment you might need includes a steamer basket, non-stick frying pan, grill, or baking sheet, among others. Always ensure the tempeh is cooked through to the center, and enjoy experimenting with different flavor combinations and cooking techniques.
