I have always been fascinated by the art of making tempeh from scratch, and I’m excited to share my favorite way to do it with you: How to Make Tempeh in the Instant Pot Recipe. This method transforms simple soybeans into a beautifully fermented, protein-packed staple that’s perfect for so many meals. Using the Instant Pot takes much of the guesswork and hard work out of traditional tempeh making, making it surprisingly approachable and rewarding.
Why You’ll Love This How to Make Tempeh in the Instant Pot Recipe
What I love most about this recipe is its unique flavor profile. The fermentation process gives the tempeh a luscious nutty and slightly earthy taste that I find deeply satisfying. When you bite into the finished product, there’s this wonderful texture that’s both firm and slightly chewy, making it a versatile ingredient in any dish. Using the Instant Pot to cook and incubate the soybeans creates a consistent environment that helps the tempeh develop that amazing depth of flavor every time.
Another thing that really stands out to me about this recipe is how manageable it is even if you’ve never fermented anything before. The Instant Pot’s precise temperature control removes much of the guesswork and hassle I remember from trying to ferment tempeh traditionally. It’s incredibly straightforward, letting me focus on other things while the tempeh does its magic inside the pot. Whether you’re prepping for a casual weeknight dinner or looking for a homemade item to impress guests at a party, this tempeh recipe fits the bill perfectly. It’s so rewarding to serve something homemade, and people always ask for the recipe when they taste it!
Ingredients You’ll Need
The ingredients for this recipe are delightfully simple, yet each one plays a crucial role in getting the perfect texture and flavor of homemade tempeh. You’ll only need a few basics, but together they set the stage for delicious results.
- Soybeans (2 cups): The heart of your tempeh, whole or dehulled split, these provide protein and the perfect fermentation base.
- Water (6 cups): Essential for soaking, cooking, and incubating the soybeans, it keeps everything moist and helps the fermentation process.
- White vinegar (1 tbsp): This slightly acidic touch helps create an ideal environment for the tempeh starter to work.
- Tempeh starter (1 tsp): The magic ingredient filled with spores that transform boiled soybeans into that signature tempeh texture and flavor.
Directions
Step 1: If you’re using whole soybeans, start by soaking them in a large bowl covered with water for 16 to 24 hours. This soaking softens the beans and makes them easier to hull later.
Step 2: After soaking, rinse the soybeans and fill the bowl with fresh water. Using your hands, gently massage the beans to remove the hulls, which will float to the surface. Skim off and discard these hulls – don’t worry if you don’t get them all, removing most is just fine.
Step 3: Drain the soybeans and place them in your Instant Pot. Cover with 6 cups of water, then pressure cook them for 12 minutes (for whole soybeans). If using dehulled split soybeans, rinse them thoroughly a few times, drain, then pressure cook covered in 6 cups water for 40 minutes with natural pressure release, which takes roughly 25 minutes.
Step 4: Once cooked, drain the soybeans and transfer them to a clean kitchen towel. Let them rest for 15 to 20 minutes to dry off any excess moisture. They should be moist but not wet; pressing gently with an additional towel can help absorb extra water.
Step 5: Move the soybeans to a large bowl and stir in the tablespoon of white vinegar to create the right acidity for fermentation.
Step 6: Sprinkle the tempeh starter over the soybeans and stir well with a wooden spoon to distribute it evenly throughout the beans.
Step 7: Prepare two small freezer bags by piercing holes every inch or so with a fork or chopstick—this allows air circulation needed for fermentation. Divide the soybeans between the two bags, packing them tightly into loaf shapes. Fold the excess bag material over the beans to secure them.
Step 8: Pour 1 cup of water into the Instant Pot liner and place the steamer rack inside. Arrange the soybean loaves on the rack, making sure the bags don’t touch the water.
Step 9: Cover the Instant Pot with a glass lid or, if unavailable, the Instant Pot’s own lid (without sealing). Press the Yogurt button 3 times to set it to the ‘Less’ mode and then adjust the timer to 32 hours for incubation.
Step 10: When the timer ends, turn the Instant Pot off but leave the tempeh inside for another 12 to 24 hours — this extra time helps the loaves firm up and develop the signature white coating. Once firm and white, your tempeh is ready to refrigerate or enjoy immediately!
Servings and Timing
This recipe yields about 2 servings of fresh homemade tempeh, perfect for trying out new flavors or incorporating into your favorite dishes. The prep time stretches over 16 to 24 hours depending on how long you soak the soybeans, but your hands-on time is quite manageable each day. The pressure cooking step takes between 12 to 40 minutes depending on your soybeans, and the fermentation process inside the Instant Pot lasts roughly 32 hours, followed by another 12 to 24 hours of resting to achieve ideal texture. Total time from start to finish may be about 49 to 50 hours, but much of this is passive soaking and incubating. The result is absolutely worth the wait!
How to Serve This How to Make Tempeh in the Instant Pot Recipe
I love serving this tempeh hot or warm, especially when pan-fried or grilled to enhance its nutty, meaty flavor. It pairs beautifully with Asian-inspired dishes like stir-fries, rice bowls, or even tossed into spicy peanut sauces. For a simple meal, slice and marinate it in soy sauce or a tangy vinaigrette, then add it to fresh salads or serve atop steamed veggies.
For presentation, I often garnish tempeh with sliced green onions, sesame seeds, or fresh herbs like cilantro and mint to add a burst of color and freshness. If you’re looking to impress, serve neatly sliced tempeh loaves on a wooden board alongside dipping sauces like hoisin, sriracha mayo, or a tangy tamarind sauce for added flavor contrast.
When it comes to drinks, I find a crisp white wine like Sauvignon Blanc or a cold glass of jasmine iced tea complements the earthy and slightly fermented notes perfectly. This tempeh recipe makes an excellent choice for family dinners, casual weeknight meals, or even as a unique and healthy option at parties where you want to introduce guests to something special.
Variations
I’ve experimented with a few swaps and twists when making this tempeh and have some great ideas you might want to try. If you can’t find whole soybeans, don’t worry—dehulled split soybeans work just as well and can even speed up the soaking and hull removal process. For those who prefer a gluten-free or vegan diet, this recipe is naturally both, making it a fabulous plant-based protein without any modifications needed.
To change up the flavor profile, I sometimes add finely minced garlic or ginger to the soybeans before incubating, or toss in a pinch of smoked paprika for a smoky twist. While the Instant Pot incubation is my go-to for ease and consistency, you can ferment tempeh in a warm spot under a heating mat or in a yogurt maker if you prefer. Just keep the temperature steady between 86 to 90 degrees Fahrenheit for best results.
Lastly, once your tempeh is ready, try experimenting with different cooking methods like baking, steaming, or crumbling it into sauces and burgers. The homemade tempeh absorbs flavors beautifully, making it a versatile canvas for countless dishes.
Storage and Reheating
Storing Leftovers
When I have leftover tempeh, I store it in an airtight container in the refrigerator to keep it fresh and firm. Using glass or BPA-free plastic containers works well to prevent odors from other foods mixing in. It will stay good for up to two weeks, giving me plenty of time to use it in a variety of recipes before it loses its prime texture.
Freezing
This tempeh freezes amazingly, which I appreciate when making larger batches. To freeze, I wrap it tightly in plastic wrap or parchment paper, then place it in a freezer-safe bag or container. It holds up well for up to six months. When you’re ready to eat it, thaw it in the fridge overnight for best results before reheating.
Reheating
To reheat tempeh without losing its hearty texture, I like to pan-fry it gently over medium heat or bake it at 350°F for about 10-15 minutes until warmed through and slightly crispy. Avoid microwaving if possible, as this can make the tempeh rubbery or dry. Reheating slowly helps restore the lovely firmness and flavor I fell in love with originally.
FAQs
Can I use other beans instead of soybeans for this tempeh recipe?
While soybeans are traditional and provide the best texture and flavor, you can experiment with other beans like black beans, chickpeas, or even lentils. Keep in mind the fermentation time and texture might vary, and you might need to adjust soaking and cooking times accordingly.
What happens if my tempeh isn’t fully white after incubation?
If the tempeh remains patchy or gray, it might need more incubation time or the temperature wasn’t ideal for fermentation. Make sure the Instant Pot or incubation environment stays warm but not hot, and be patient – sometimes it just takes an extra day or two for the white mycelium to fully cover the soybeans.
Is it safe to eat tempeh if I see some black or pink spots?
White mycelium is what you want to see on tempeh. Black spots are usually the expected natural mold spores but pink or red spots mean contamination, and it’s best to discard that batch to avoid any risk. Always rely on smell and appearance: a pleasant nutty aroma indicates good fermentation.
Can I speed up the fermentation time?
The fermentation time is important to get a firm texture and develop flavor. While you might see some changes sooner, rushing it can result in underdeveloped tempeh. Keeping your Instant Pot at a reliable “Less” Yogurt setting ensures a steady temperature, which is key for great results.
How do I use homemade tempeh in cooking?
Homemade tempeh can be sliced, cubed, or crumbled and used in countless recipes like stir-fries, sandwiches, salads, or baked dishes. I especially love marinating it before cooking to enhance its naturally nutty flavor and adding it to grain bowls for a healthy protein boost.
