Tempeh: properties, benefits and how to cook it
Complete plant-based proteins, fiber, fermentation… Tempeh stands out as one of the most complete ingredients in a plant-based diet. Origins, nutritional value, benefits, and recipes — everything you need to know.
Tempeh, much more than a plant-based alternative to meat
In a context where more and more people are looking to reduce their meat consumption and diversify their protein sources, tempeh has emerged as one of the most appealing options. It aligns with both the trend towards complete plant-based proteins and that of traditional fermented foods , which have been valued for centuries in many culinary cultures.
Its firm texture, slightly intense taste and versatility in cooking make it a choice ingredient for vegetarians and vegans as well as flexitarians.
What is tempeh?
Tempeh is a food made from fermented soybeans , presented in a compact block form. Unlike other soy derivatives such as tofu or soy milk, it is made with the whole grain — which allows it to retain a large portion of its original fiber and nutrients.
It is a 100% plant-based product which, after fermentation, acquires a firm, slightly grainy texture and a subtle taste with notes of nuts and umami. It is naturally rich in protein, fiber, and B vitamins.
The traditional manufacturing process
Tempeh is obtained through a controlled natural fermentation process. Here are the key steps:
The grains are soaked for several hours to soften them, then their outer husks are removed.
The grains are steamed or boiled briefly to soften them, without breaking their structure.
The grains are inoculated with the fungus Rhizopus oligosporus , the traditional culture used for fermenting tempeh.
At a warm temperature, the fungus develops a network of white mycelium that envelops and binds the grains together, forming the characteristic compact block. This process gives tempeh its distinctive texture, taste, and properties.
Tempeh comes in various forms made with other legumes (chickpeas, black beans, lentils) or grains (barley, rice), offering different flavor profiles. Soy tempeh remains the most widespread and nutritionally well-documented version.
Origins: a treasure of Indonesian cuisine
Tempeh originated in Indonesia , specifically on the island of Java, where it has been consumed for centuries as a staple food. In its country of origin, it is part of the daily diet and is prepared in many ways: fried, steamed, simmered, or incorporated into soups and curries.
With the expansion of Asian cuisine and the global resurgence of interest in plant-based foods, tempeh began to gain popularity in Europe and America from the late 20th century. Today, it is produced locally in many European countries—notably France, the Netherlands, and Germany—making it more accessible and ensuring greater freshness.
The first written records of tempeh date back to the 18th century in Java, but its consumption is probably much older. It represents one of the rare examples of a fermented legume-based food that has gone from a traditional subsistence food to international recognition as a superfood — alongside Japanese miso or Korean kimchi.
Tempeh vs tofu: what are the differences?
Although both are derived from soy, tempeh and tofu are very different products in terms of nutrition, taste and culinary qualities.
| Criteria | Tempeh | Tofu |
|---|---|---|
| Manufacturing | Fermented whole grain | Coagulated soy beverage |
| Fibers | ✅ Rich in fiber | Almost no fiber |
| Protein (per 100g) | ~19-20 g | ~8-12 g (depending on firmness) |
| Texture | Firm, granular, compact | Soft to silky |
| Flavor | Pronounced, with notes of nuts and umami | Neutral, absorbs flavors |
| Fermentation | ✅ Yes — traditional live food | No |
| Cooking adapted | Sautéed, grilled, roasted, crumbled | Pan-fried, simmered, in soup |
Tempeh and tofu are complementary, not interchangeable . Tempeh is ideal for preparations that require firmness (salteados, veggie burgers, marinades) — tofu is better suited to creamy recipes or dishes where you want the ingredient to absorb the sauce (curry, miso soup, lasagna).
Nutritional properties of tempeh
Tempeh has a remarkable nutritional profile among plant-based foods. Its nutrient density makes it a satiating and effective food for creating balanced meals.
~19-20 g per 100 g. Contains all 9 essential amino acids — a rarity among plants.
~9g per 100g. The whole grain retains all its fibers, which are absent from tofu.
Primarily mono- and polyunsaturated fatty acids that are beneficial for cardiovascular health.
An interesting source of non-heme iron and magnesium, particularly useful for vegetarian diets.
Riboflavin (B2), niacin (B3), pyridoxine (B6) — essential for energy metabolism.
Contributes to bone health — particularly relevant in dairy-free diets.
Fermentation partially transforms the compounds in soy, including antinutrients (phytic acid, protease inhibitors) that reduce mineral absorption in unfermented legumes. Tempeh is therefore often better tolerated and easier to digest than other unfermented soy derivatives (tofu, soy milk, cooked edamame). This is one of its distinctive advantages for people sensitive to legumes.
Health benefits of tempeh
No single food has miraculous effects when consumed in isolation. However, as part of a balanced diet and an active lifestyle, tempeh can provide real and measurable nutritional benefits.
Contributes to the maintenance of muscle mass
Thanks to its complete protein content—providing all nine essential amino acids, including leucine, key to muscle protein synthesis—tempeh supports the maintenance and development of muscle mass, especially when combined with regular physical activity. It is one of the few plant-based sources that can rival animal protein in terms of quality.
A complete plant-based alternative to meat
Tempeh can help diversify your diet by offering a protein-rich, plant-based alternative to meat products. Its nutritional profile makes it a particularly suitable option for:
Vegetarians and vegans seeking complete proteins · People wishing to reduce their meat consumption · Flexitarians seeking variety · Athletes looking for diverse protein sources · People wishing to reduce their food-related environmental impact
Digestive health and microbiota
As a traditional fermented food, tempeh fits naturally into a diet rich in vegetables and fermented foods, which is associated with a greater diversity of the gut microbiota. Its fiber content also contributes to regular bowel movements and provides a favorable substrate for beneficial gut bacteria .
Bone health
The protein and mineral (calcium, phosphorus, magnesium) content of tempeh contributes to maintaining bone health under normal conditions — particularly beneficial in dairy-free diets where these intakes may be insufficient.
Soy allergy: Tempeh is contraindicated for people with soy allergies — always read the label.
Specific digestive disorders: In case of severe irritable bowel syndrome or SIBO (small intestinal bacterial overgrowth), consult a healthcare professional before introducing new fermented foods.
Soy isoflavones: if you have a history of hormone-dependent cancers, ask your doctor for advice.
How to cook tempeh
One of tempeh's great advantages is its culinary versatility . Its firm texture allows it to withstand many cooking techniques without falling apart — something tofu can't always do.
Marinated and then grilled slices: tempeh develops a golden crust and an intense flavor. Ideal as a plant-based steak substitute.
Diced or sliced with oil, tamari and spices. 20 minutes at 200°C gives a crispy exterior and a melting interior.
Chopped with vegetables, soy sauce and sesame. The original Asian technique — quick, tasty and nutritious.
Crumbled and seasoned, it perfectly replaces minced meat in tacos, vegetable bolognese or stuffed vegetables.
Tempeh absorbs the flavors of spicy sauces, curries, and stews wonderfully. Ideal for casserole dishes.
In small roasted cubes, it adds texture and protein to soups, salads and bowls — a very popular alternative to croutons.
Reduce the natural bitterness of tempeh
Tempeh can have a slightly bitter taste naturally. A few simple steps will completely neutralize it:
1. Steam for 5 to 10 minutes before cooking — this is the most effective method: it eliminates bitterness and improves the penetration of the marinade's flavors.
2. Marinate for at least 30 minutes (ideally 2 hours or overnight) in a mixture of tamari + sesame oil + garlic + ginger.
3. Use spices and aromatic herbs generously: cumin, smoked paprika, turmeric, garlic, lemon, sriracha sauce — tempeh supports and enhances strong flavors.

How to choose your tempeh
The quality of tempeh varies depending on its origin, the production process, and the ingredients used. Here are some criteria to help you make the best choice.
Short ingredient list: ideally soy (or other legume), starter culture ( Rhizopus ), and salt. The shorter the list, the better the product.
Refrigerated format: prefer fresh chilled tempeh to long-life pasteurized tempeh — it retains its properties and texture better.
Appearance and color: the white mycelium should be uniform. Tempeh with black or grey areas may indicate excessive fermentation or spoilage.
Organic if possible: organic tempeh guarantees the absence of GMOs (conventional soy is often genetically modified) and more sustainable agricultural practices.
Check for allergens: some industrial tempeh contains additives or is manufactured in facilities that process other allergens (gluten, nuts).
