I am so excited to share my Homemade Tempeh in the Instant Pot Recipe with you because tempeh has become one of my favorite plant-based proteins to cook with. This recipe is a labor of love that transforms simple soybeans into a wonderfully firm, nutty, and slightly tangy tempeh using the magic of my Instant Pot. I love how this recipe makes a traditionally time-consuming process manageable and fun, and the results are incredibly rewarding. If you’ve ever thought about making tempeh at home, this recipe will be your new go-to because it’s straightforward and yields delicious, fresh tempeh every time.
Why You’ll Love This Homemade Tempeh in the Instant Pot Recipe
One of the things I absolutely adore about making tempeh at home using this recipe is the flavor profile. The tempeh comes out with a delicate nutty taste that’s perfectly balanced with a subtle tang from the fermentation process. It’s not overpowering but just enough to give it character. The texture is firm yet tender, which makes it incredibly versatile for cooking. You can slice it, crumble it, or cube it and it holds up beautifully when pan-fried, baked, or grilled.
What truly sets this Homemade Tempeh in the Instant Pot Recipe apart is how accessible and easy it is, especially for anyone intimidated by fermentation. The Instant Pot takes away so much guesswork and effort by creating the perfect incubating environment. Plus, it frees up my stove and oven, which is a huge bonus when I’m juggling multiple dishes. I love serving this homemade tempeh at casual weekday dinners, vegan feasts, or whenever I want to impress friends with a unique plant-based protein. It’s a recipe I keep coming back to, and I know you will too.
Ingredients You’ll Need
The ingredients for this recipe are wonderfully simple but crucial — each one plays a key role in shaping the flavor, texture, and fermentation process of your tempeh. These basic items allow the natural flavor of the soybeans to shine through and the tempeh starter to do its magic.
- Soybeans (2 cups, whole or dehulled split): The foundation of your tempeh, providing protein and that classic tempeh chew.
- Water (6 cups): Needed for soaking, cooking, and incubating the soybeans properly.
- White vinegar (1 tbsp): Helps acidify the soybeans slightly, creating an ideal environment for fermentation.
- Tempeh starter (1 tsp): Contains the rhizopus spores responsible for fermenting and binding the soybeans together.
Directions
Step 1: If you’re using whole soybeans, start by soaking them in plenty of water for 16 to 24 hours. This rehydrates the beans and softens their hulls, which will help the fermentation process.
Step 2: After soaking, rinse the beans and massage them gently in water to remove most of the skins. The hulls will float to the surface, so scoop them out with a colander. Don’t worry if you can’t remove all the skins — most is fine, and I usually end up with about a cup of skins removed from this batch size.
Step 3: Drain the soybeans and place them in the Instant Pot. Cover with 6 cups of water and pressure cook for 12 minutes. If you’re using dehulled split soybeans, skip soaking and rinsing — just rinse thoroughly, then pressure cook with 6 cups of water for 40 minutes, letting the pressure release naturally for about 25 minutes.
Step 4: Once the soybeans are cooked, drain them thoroughly and transfer them onto a clean kitchen towel. Let the beans dry for 15 to 20 minutes or gently press out excess moisture with another towel; the beans need to be dry enough for fermentation to work properly.
Step 5: Transfer the dried soybeans to a large mixing bowl. Add 1 tablespoon of white vinegar and stir well with a wooden spoon to distribute the acidity evenly, which helps create the right fermentation environment.
Step 6: Sprinkle 1 teaspoon of tempeh starter over the soybeans and stir gently but thoroughly to ensure it’s evenly mixed throughout the beans. This is what brings your tempeh to life!
Step 7: Divide the mixture evenly into two small freezer bags. Pierce the bags with a fork or chopstick every inch or so to allow airflow. Pack the soybeans tightly inside, forming thick rectangular loaves. Fold the rest of the bag to seal it snugly around the beans.
Step 8: Pour 1 cup of water into the Instant Pot liner and place the steamer rack inside. Lay the soybean loaves on the rack, making sure they don’t touch the water.
Step 9: Cover the Instant Pot with a glass lid or the Instant Pot lid (if you don’t have a glass lid). Press the Yogurt button three times to select “Less” mode, and set the timer for 32 hours to incubate. After this period, turn off the Instant Pot and let the tempeh incubate inside for another 12 to 24 hours until the loaves are firm and completely white with the characteristic tempeh mold.
Step 10: Your homemade tempeh is now ready! Remove it from the bags, and either use it immediately in your favorite dishes or store it in the refrigerator.
Servings and Timing
This recipe makes about 2 servings of tempeh, perfect for two hearty meals or to share with a friend. Prep time including soaking is variable — expect about 16 to 24 hours soaking time plus 20 minutes active prep. The Instant Pot cooking takes 12 to 40 minutes depending on the soybean type, followed by an incubation period of roughly 44 to 56 hours including resting time. While this timeline might seem long, most of it is hands-off, allowing the fermentation process to work its magic.
How to Serve This Homemade Tempeh in the Instant Pot Recipe
I love serving this homemade tempeh in so many ways! It’s incredible when pan-fried with a dash of soy sauce and served alongside steamed veggies and brown rice for a simple weeknight meal. The nutty flavor pairs beautifully with Asian-inspired dishes, but don’t hesitate to crumble it into chili or tacos for an unexpected twist.
Presentation-wise, I like slicing the tempeh into neat rectangular pieces that show off the white textured interior. Garnishing with fresh herbs like cilantro or a sprinkle of toasted sesame seeds always adds a touch of brightness. For beverages, I find this tempeh pairs wonderfully with a crisp white wine like Sauvignon Blanc or even a light, hoppy beer. For non-alcoholic options, a cold jasmine tea makes a refreshing complement.
This recipe is perfect for any occasion — whether you’re hosting a casual family dinner, bringing vegan fare to holiday gatherings, or preparing ahead for a party. The tempeh can be enjoyed warm, straight from the pan, or even chilled in summer salads. Portion sizes of around 100 grams per person work well when served as a main protein.
Variations
I love experimenting with this recipe to suit different tastes and dietary needs. If you want to skip soy, you can try making tempeh with other beans like black beans or chickpeas, though cooking and fermentation times might vary slightly. For gluten-free eaters, this recipe is naturally gluten-free, but just double-check your tempeh starter ingredients.
Flavor-wise, adding seasonings like garlic powder, smoked paprika, or nutritional yeast before packing the beans into bags gives your tempeh a fun personality. I’ve also enjoyed marinating thick slices in tamari and maple syrup before grilling for a sweet-savory edge.
If you don’t have an Instant Pot, you can incubate the tempeh by wrapping the bags in towels and placing them in a warm oven set to about 85°F (29°C) or using a dedicated fermenter, but I find the Instant Pot method much simpler and more reliable. This recipe is such a fun starting point for many creative cooking adventures!
Storage and Reheating
Storing Leftovers
Once your tempeh is fully fermented and cooled, I recommend storing it in an airtight container or wrapping it tightly with plastic wrap in the refrigerator. It will keep fresh for up to 2 weeks. I usually slice it into portions before refrigerating, which makes reheating a breeze. Keeping it dry inside the storage container helps maintain the best texture.
Freezing
This homemade tempeh freezes beautifully! Wrap portions tightly in plastic wrap and place them in a freezer-safe bag or container. It keeps well for up to 6 months in the freezer. When you’re ready to use it, thaw slowly in the refrigerator overnight for best results. Avoid freezing if the tempeh is still very moist, as ice crystals can affect texture.
Reheating
When it’s time to reheat, I find gentle methods like pan-frying, grilling, or baking deliver the best texture and flavor. These methods help dry out the surface slightly and enhance the nutty aroma. Avoid microwaving, as it can make the tempeh rubbery and unevenly heated. Also, make sure not to overcook it — just sufficient warming to enjoy its flavor and texture fully.
FAQs
Can I use other beans besides soybeans to make tempeh?
Yes, you can! While soybeans are traditional, other beans like chickpeas, black beans, or even a mix of legumes can be used to make tempeh. Keep in mind the cooking and fermentation times might vary, and the texture and flavor will be slightly different, but it’s a fun way to customize your tempeh experience.
How do I know when my tempeh is fully fermented?
Fully fermented tempeh will have a firm texture and be covered in a white, mat-like layer of rhizopus mold. The loaves should be compact, and the smell will be slightly nutty and earthy but never sour or unpleasant. If you see any pink, black, or fuzzy colors, discard the batch, as these indicate contamination.
What if my tempeh turns out too wet or mushy?
Excess moisture can prevent proper fermentation and cause mushy tempeh. Make sure to dry your cooked soybeans thoroughly before adding the starter, as outlined in the recipe. Also, ensure the bags are pierced to allow airflow during incubation. If mushiness happens, try a longer incubation time or drier beans next time.
Can I skip the vinegar in this recipe?
The vinegar helps acidify the soybeans slightly, creating the right environment for fermentation and preventing unwanted bacteria. While you might skip it, I recommend keeping it in the recipe to ensure consistent, safe fermentation and that classic tempeh flavor.
What can I cook with homemade tempeh?
Tempeh is so versatile! You can marinate and grill it, crumble it into tacos or chili, bake it with spices, or pan-fry it for sandwiches and salads. Its firm texture holds up well to a variety of cuisines and cooking methods, making it a fantastic addition to any plant-based or protein-rich meal.
