One of the most common questions I get: tempeh or tofu? Both are made from soybeans, both are protein-rich, and both are staples in plant-based cooking – but they are two very different products with different nutrition profiles, textures, and best uses.
What's the difference between tempeh and tofu?
Tofu is made from soy milk that has been curdled (similar to cheesemaking), pressed, and formed into blocks. It has a mild flavor and a soft to firm texture depending on the variety.
Tempeh is made from whole soybeans that have been fermented with a fungus called Rhizopus. The result: a dense cake with a nutty flavor and much higher levels of fiber, protein, and probiotics.

When to choose tempeh
- When you want more protein and fiber – 20g protein and 5g fiber per 100g.
- When you want a meatier texture – ideal for stir-fries, sandwiches, or vegan bacon.
- When gut health matters – fermentation creates probiotics that feed beneficial gut bacteria.
- When you prefer minimally processed soy – tempeh is the whole-food form of soy.
When to choose tofu
- When you want a neutral flavor that absorbs marinades – curries, shakshuka, Asian dishes.
- When you need a soft or creamy texture – silken tofu for sauces, desserts, smoothies.
- When you want fewer calories – tofu has about 50 fewer calories per 100g.
- When you need bioavailable calcium – calcium-set tofu is one of the best plant sources.
Which is healthier?
Both are healthy – for different reasons. Tempeh wins on fiber, probiotics, and protein, and fermentation makes it easier to digest while reducing anti-nutrients that block mineral absorption. Tofu wins on culinary versatility, calcium content, and price.
My recommendation: use both. Tempeh 2–3 times a week as your main protein source, tofu whenever you need something that absorbs flavor or has a soft texture.
How to prepare each one
Tempeh: Slice thin, steam for 10 minutes (removes bitterness), then pan-sear or bake with soy sauce, maple syrup, and garlic.
Tofu: Press well with a kitchen towel for 15 minutes, cube, toss with a little cornstarch, and bake at 400°F (200°C) for 25 minutes.
Frequently asked questions
Is tempeh healthier than tofu?
Tempeh has more protein, fiber, and probiotics, while tofu provides more calcium and fewer calories. Both are healthy within a balanced diet.
Which has more protein, tempeh or tofu?
Tempeh contains about 20g of protein per 100g, compared to about 17g in firm tofu.
Is tempeh fermented soy?
Yes. The fermentation with Rhizopus fungus is what distinguishes it from tofu and gives it its nutty flavor and probiotic benefits.
Which is better for weight loss?
Tofu has fewer calories, but tempeh is more filling thanks to its fiber and protein. Both work well in a weight-loss diet.
