How Long Does Tempeh Last?
Opened tempeh lasts 5–7 days in the fridge, tightly wrapped, and cooked tempeh 3–4 days. Unopened, it keeps until the date on the pack, and it freezes well for 3–6 months.
Tempeh — opened
shelf life- Cooked: 3–4 days in the fridge
- Homemade: 3–5 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Tempeh is a firm cake of cooked soybeans bound together by a white mold culture, Rhizopus, during a short fermentation. Most store-bought tempeh is pasteurized and vacuum-sealed, which stops the culture. Once opened, the dense, protein-rich cake is open to other molds and bacteria. Black or gray spots are the culture maturing and are not a defect.
How to store tempeh
- Wrap the unused portion tightly in plastic wrap or seal it in a small airtight container. Exposed tempeh dries at the cut edge and picks up stray mold from the fridge.
- Freeze extra tempeh in its unopened vacuum pack, or cut into slices first. It is one of the few soy foods whose texture is essentially unchanged by freezing.
- Thaw it overnight in the fridge, or steam frozen slices for 10 minutes, which thaws them and also mellows tempeh's slight bitterness before marinating.
- Store cooked or marinated tempeh in a sealed container and refrigerate it within 2 hours; discard used marinade instead of keeping it.
How to tell if tempeh has gone bad
- A strong ammonia, alcohol or rotten smell. Good tempeh smells nutty, mushroomy and mildly yeasty.
- A slimy, sticky or mushy surface, or beans that crumble apart wetly instead of holding together as a firm cake.
- Fuzzy mold in colors such as green, blue, pink, yellow or orange. White mycelium and flat black or gray patches are part of the normal culture.
- A sealed package that has swollen tight with gas.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.
Tempeh shelf life chart
| State | Fridge | Freezer | Pantry |
|---|---|---|---|
| Opened | 5–7 days | 3–6 months | Not safe |
| Unopened refrigerated tempeh keeps until the use-by date on the pack. Follow the label if it gives fewer days after opening. | |||
| Cooked | 3–4 days | 2–3 months | Not safe |
| Homemade | 3–5 days | 3–6 months | Not safe |
| Fresh, unpasteurized tempeh keeps fermenting slowly in the fridge; freeze it for longer storage. | |||
Not safe = perishable: no more than 2 hours at room temperature (1 hour above 90°F / 32°C). Not recommended = possible, but quality suffers or it serves no purpose.
Frequently asked questions
Are black spots on tempeh safe?
Yes. Black or gray spots and veins on tempeh are where the Rhizopus culture has matured and produced spores, much like the veining in blue cheese. They are harmless and do not affect flavor much. Worry instead about sliminess, an ammonia smell, or fuzzy mold in other colors such as green, pink or orange.
How long does tempeh last in the fridge once opened?
Opened tempeh lasts 5–7 days in the fridge if it is wrapped tightly, and some packages advise using it sooner, in which case follow the package. Cooked tempeh keeps 3–4 days. If you will not use the rest of the block within the week, freeze it the day you open it.
Does tempeh need to be cooked?
Cooking is recommended. Pasteurized store-bought tempeh is technically ready to eat, but package directions commonly say to cook it, and steaming, frying or baking improves both flavor and safety. Fresh or homemade unpasteurized tempeh should always be cooked thoroughly before eating.
Can you freeze tempeh?
Yes, tempeh freezes very well for 3–6 months at best quality, and it remains safe beyond that at 0°F (−18°C). Its firm structure does not turn spongy the way tofu does. Freeze it sealed, thaw in the fridge, and use it within a few days of thawing.
