Calories in Tempeh: Full Nutrition Breakdown

Tempeh is a traditional Indonesian food made from fermented soybeans that are bound together into a firm, dense cake. One cup of sliced tempeh provides roughly 34 grams of protein, 16 grams of carbohydrates, and is an excellent source of manganese, copper, phosphorus, and riboflavin. Its nutty, earthy flavor and firm texture make it one of the most popular plant-based protein sources worldwide.

Calories by serving size:

Tempeh also stands out for its fermentation process, which improves the digestibility of soy protein and increases the bioavailability of minerals like iron and zinc. A single cup delivers about 2.2 mg of manganese (over 95% of the daily value) and roughly 18 grams of fat, most of which is heart-healthy unsaturated fat.

Frequently Asked Questions (FAQ)

How does tempeh compare to tofu nutritionally?

Tempeh is significantly more nutrient-dense than tofu because it uses whole soybeans rather than just soy milk curds. A cup of tempeh has about 319 calories and 34 grams of protein, while a cup of firm tofu has roughly 183 calories and 20 grams of protein. Tempeh also provides considerably more fiber, iron, and B vitamins due to the intact soybean structure and fermentation process.

How much protein does tempeh have per serving?

One cup of sliced tempeh provides approximately 34 grams of protein, making it one of the highest-protein plant foods available. Even a modest 3-ounce serving delivers about 17 grams of protein, comparable to the protein in 2.5 large eggs. This protein is also complete, containing all nine essential amino acids in adequate amounts.

Is tempeh fermented, and does it have probiotics?

Yes, tempeh is made by fermenting cooked soybeans with a mold culture called Rhizopus oligosporus, which binds the beans into a firm cake. This fermentation process produces beneficial enzymes and improves nutrient absorption, but most commercial tempeh is pasteurized, which kills live probiotic organisms. Unpasteurized or homemade tempeh may retain some live cultures, though it is primarily valued for its improved digestibility rather than probiotic content.

How does tempeh compare to chicken for protein?

Tempeh and chicken breast are surprisingly comparable in protein density per calorie. A 3-ounce serving of tempeh provides about 17 grams of protein with 162 calories, while the same amount of cooked chicken breast provides about 26 grams of protein with 128 calories. While chicken is leaner and more protein-dense, tempeh offers fiber, prebiotics, and phytonutrients that chicken does not provide.

What is the best way to cook tempeh?

Tempeh benefits from steaming or simmering for 10 minutes before marinating, which removes any residual bitterness and opens the pores for better flavor absorption. After steaming, it can be sliced and pan-fried, baked, grilled, or crumbled into dishes like stir-fries, tacos, and grain bowls. Marinating tempeh in soy sauce, garlic, and a touch of vinegar or citrus for at least 30 minutes produces the best flavor results.
