Tempeh vs. Tofu: Nutrition, Benefits, and How to Choose
Explore the differences, nutritional value, benefits, and best uses of tempeh and tofu for plant-based eating.
Tempeh and tofu are two of the most popular plant-based protein sources, especially among vegetarians and vegans. While both are made from soybeans and offer significant nutritional benefits, they differ in how they are produced, their nutrient profiles, taste, texture, and culinary uses. Whether you’re seeking to add variety to your diet, boost your protein intake, or make informed plant-based choices, understanding the distinctions between tempeh and tofu can help you decide what works best for your health and palate.
Understanding Tempeh and Tofu
Both tempeh and tofu start with soybeans, but their production processes and resulting structures diverge considerably.
- Tempeh is made by fermenting whole soybeans, sometimes with the addition of grains or seeds. The beans are bound together by a white mold (Rhizopus), forming a firm, cake-like texture. This fermentation process gives tempeh its signature earthy, nutty flavor and a dense consistency.
- Tofu, commonly known as bean curd, is created by coagulating soy milk and pressing the resulting curds into soft white blocks. The flavor is neutral and the texture can range from soft and silken to extra-firm, depending on water content and processing.
Nutrition Showdown: Tempeh vs. Tofu
Both tempeh and tofu are considered nutrient-dense, but they have notable differences in their nutritional profiles.
| Nutrition | Tempeh | Tofu |
|---|---|---|
| Calories | 167 | 94 |
| Protein | 19.0g | 9.4g |
| Fat | 5.4g | 5.3g |
| Carbohydrates | 11.9g | 2.4g |
| Fiber | 8.3g | 2.4g |
| Sugar | 0g | 0g |
| Calcium (% DV) | 9% | 43% |
| Iron (% DV) | 15% | 15% |
| Potassium (% DV) | 9% | 5% |
| Phosphorus (% DV) | 21% | 15% |
Several trends stand out:
- Tempeh is higher in protein, fiber, and calories, thanks to its use of whole soybeans and fermentation process.
- Tofu is lower in calories and carbohydrates, and contains more calcium, especially when prepared with calcium coagulants. Its texture also lends itself to a wider range of culinary applications due to water content variability.
Production: How Tempeh and Tofu Are Made
Tempeh Production
Tempeh is made by boiling and dehulling soybeans, then inoculating them with a beneficial mold before allowing them to ferment for about 24–48 hours. The beans stick together in a firm, sliceable cake. Some varieties include added grains or seeds for variety and additional nutrients.
Tofu Production
Tofu production involves soaking, grinding, and boiling soybeans to create soy milk, which is then coagulated (with nigari, glucono delta-lactone, or calcium sulfate). The resulting curds are pressed into blocks and can be categorized into silken, soft, firm, or extra-firm, depending on how much water is pressed out.
Health Benefits of Tempeh and Tofu
- Complete Protein: Both tempeh and tofu contain all nine essential amino acids, making them excellent sources of complete plant-based protein.
- Gut Health: Tempeh’s fermentation process produces beneficial prebiotics and probiotics, supporting a healthy gut microbiome and digestion.
- Heart Health: Isoflavones found in both tempeh and tofu have been linked to reduced LDL cholesterol and improved cardiovascular health.
- Digestive Health: The high fiber in tempeh regulates bowel movements, while tofu, though lower in fiber, may be easier to digest for some people due to its lack of fermentation.
- Bone Health: Both provide minerals vital for bone strength. Tofu, with higher calcium, particularly benefits bone density, while tempeh contributes phosphorus and plant-based calcium.
- Low Sodium & Cholesterol-Free: Both foods are naturally low in sodium and contain no cholesterol, making them heart-friendly protein options.

Taste and Texture: What to Expect
| Property | Tempeh | Tofu |
|---|---|---|
| Taste | Nutty, earthy, slightly tangy, pronounced | Mild, neutral, easily absorbs marinades/spices |
| Texture | Firm, chewy, can be crunchy if cooked | Ranges from silken and custardy to extra firm and dense |
| Cooking Methods | Grilled, baked, sautéed, crumbled, stir-fried | Steamed, stir-fried, scrambled, blended, baked |
| Versatility | Best in hearty dishes, can stand up to strong sauces | Outstanding in soups, desserts, smoothies, frying, marinating |
Which Is Healthier?
Both foods are considered healthy and fit well into a balanced diet. The “healthier” option depends on your goals:
- If you need more protein and fiber, tempeh is superior.
- If you want lower calories, lower fat, and a softer texture for diverse culinary uses, tofu is ideal.
- Tempeh’s beneficial fermentation may appeal to those prioritizing gut health or with sensitive digestion.
- Those seeking to boost calcium intake (for bone health) may lean toward firm tofu.
Culinary Uses and Cooking Tips
Best Ways to Use Tempeh
- Stir-fries and sautés: Absorbs flavorful sauces well; browns and crisps nicely.
- Sandwiches and wraps: Sliced or crumbled, tempeh adds a hearty texture.
- Grilled or baked: Marinade and bake or grill for smoky, robust entrees.
- Tacos and salads: Crumble and season tempeh for taco filling or salad protein.
Tofu in the Kitchen
- Soups and stews: Soft (silken) tofu dissolves smoothly for creamy bases.
- Stir-fries: Firm or extra-firm tofu dices hold their shape and absorb sauces.
- Scrambled or blended: Makes vegan “scrambled eggs” or smooth desserts.
- Baked or fried: For a crispy bite, coat and bake/fry tofu cubes.
- Smoothies and desserts: Blends into creamy, high-protein desserts and drinks.
Potential Health Concerns and Considerations
- Soy Allergies: Both tempeh and tofu are unsuitable for those allergic to soy.
- Fermentation Sensitivities: Rarely, some may react to fermented foods like tempeh.
- Processing: Both are minimally processed, but check ingredient lists for additives or flavorings in store-bought versions.
- Estrogenic Effects: Phytoestrogens in soy have been studied extensively and, in moderate consumption, are considered safe for most people—including women with breast cancer history—but individuals should consult healthcare providers for personal needs.
Environmental and Ethical Considerations
- Sustainable Protein: Both tempeh and tofu offer much lower carbon footprints than animal proteins.
- Organic and GMO-Free Options: Choose organic or non-GMO verified products if you wish to avoid genetically modified soybeans.
- Supporting Local: Where possible, look for regional or artisanal producers for improved freshness and traceability.
Frequently Asked Questions (FAQs)
What are the main differences in taste and texture between tempeh and tofu?
Tempeh has a firm, chewy texture and a nutty, earthy flavor from fermentation. Tofu is soft, spongy, and neutral in taste, making it easy to marinate and use in a wide variety of recipes.
Is tempeh or tofu better for gut health?
Tempeh, being a fermented food, is more beneficial for gut health due to the presence of prebiotics and probiotics that support digestive wellness.
Which provides more calcium: tempeh or tofu?
Tofu, especially if processed with calcium-based coagulants, offers much more calcium per serving compared to tempeh.
Can you substitute tempeh for tofu in recipes?
In some recipes, yes, but be mindful of differing textures and flavors. For stir-fries and savory dishes with robust sauces, tempeh is an excellent substitute. For creamy or blended dishes, silken tofu is best.
Are there any health risks to eating soy products?
For most people, moderate soy consumption is safe and beneficial. However, those with soy allergies should avoid these foods. If you have specific health conditions (like thyroid problems or hormone-sensitive cancers), consult your physician about soy intake.
