Making tempeh at home is easier than you think — it just takes a little patience and the right conditions.
Below is a complete step-by-step guide for beginners to prepare delicious, healthy tempeh from scratch using soybeans and a fermentation culture.
🍽️ Homemade Tempeh Recipe
Prep Time: 12–24 hours
Fermentation Time: 24–48 hours
Yield: ~500g of tempeh
🧾 Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Dried soybeans | 2 cups (400g) | Organic preferred |
| Vinegar | 1–2 tablespoons | White or apple cider vinegar |
| Tempeh starter | 1 teaspoon | Contains Rhizopus oligosporus spores |
| Water | As needed | For soaking, boiling, and draining |
🧪 Where to Get Tempeh Starter?
- Purchase online from sites like Cultures for Health, TempehStarterShop, or Amazon.
- Store in the fridge or freezer to keep the spores active.
🥣 Equipment Needed
- Large pot or pressure cooker
- Strainer or colander
- Clean towel or paper towels
- Mixing bowl
- Food-grade plastic zip bags or baking pans
- Skewer/fork (for poking holes)
👨🍳 Step-by-Step Instructions
Step 1: Soak the Soybeans (Overnight)
- Rinse 2 cups of dried soybeans.
- Soak them in a large bowl with at least 6 cups of water for 8–12 hours (overnight).
- The beans will double in size.
Step 2: Dehull and Split the Soybeans
- After soaking, rub the beans between your hands to remove most of the hulls.
- Drain and rinse several times, removing floating hulls as much as possible.
- Optional: You can pulse them a few times in a food processor to split the beans.
Step 3: Cook the Beans
- Boil or pressure cook the beans until just tender but not mushy.
- Boil: 30–45 minutes
- Pressure cook: 10–15 minutes
- Drain thoroughly and let cool to room temperature.
- Important: Beans must be completely dry before adding starter.
Step 4: Add Vinegar
- Add 1–2 tablespoons of vinegar to the drained beans.
- This lowers the pH and prevents unwanted bacteria growth.
Step 5: Inoculate with Tempeh Starter
- Sprinkle 1 teaspoon of tempeh starter over the beans.
- Mix thoroughly to distribute spores evenly.
Step 6: Pack the Beans
- Place the inoculated beans into ziplock bags (1–2 cm thick layer).
- Poke small holes (every 1 inch) on both sides using a fork or skewer — air is needed for the mold to grow.
- Alternative: Use perforated glass baking trays or banana leaves.
Step 7: Ferment
- Incubate the bags at 30–32°C (86–90°F) for 24 to 48 hours.
Tips for incubation:
- Use a yogurt maker, oven with light on, seedling mat, or rice cooker “keep warm” mode.
- Keep temperature stable — too hot kills the mold, too cold slows fermentation.
✅ You’ll see a white mat-like mold forming and binding the beans together. That’s tempeh!
Step 8: Check and Finish
- When the tempeh forms a solid cake and smells nutty/earthy, it’s done.
- The mold should be white. Black or pink mold = discard and start over.
🧊 Storage
- Refrigerate up to 1 week.
- Freeze for up to 3 months.
- Cook before eating (steam, grill, fry, or bake).
🥘 How to Use Tempeh
- Stir-fry with soy sauce, garlic, and chili
- Grill with BBQ sauce
- Add to curries, salads, tacos, or sandwiches
- Crumble into pasta sauces or soups
🧠 Bonus Tip: Why Tempeh Is So Healthy
- Rich in protein, fiber, and spermidine
- Contains probiotics and enzymes from fermentation
- Easily digestible (thanks to mycelium breaking down anti-nutrients)
- Perfect for gut health, longevity, and sustainable diets
