Tempeh

Tempeh is safe during pregnancy and, cooked as it normally is, makes a nutritious, high-protein addition to the diet — a firmer, more textured alternative to tofu made from whole fermented soybeans.

Safe to eat

Tempeh is made by fermenting whole cooked soybeans with a specific mould culture, which binds them into a firm, dense cake with a noticeably nuttier, more savoury flavour and more texture than tofu, which is made from soy milk pressed into curds rather than whole fermented beans. Because it uses the whole bean rather than just the milk, tempeh retains more fibre than tofu, alongside a similar strong protein and iron profile, making it a particularly good option for vegetarian and vegan pregnancy diets looking for variety beyond tofu alone. Tempeh is almost always cooked before eating — sliced and pan-fried, baked, steamed, or added to a stir-fry or curry — which addresses any lingering food-safety question in the same straightforward way cooking does for most plant-based proteins. As with other soy foods, any phytoestrogen concern doesn't hold up against the actual human evidence at normal dietary intake levels, and tempeh's fermentation process is, if anything, an additional point in its favour rather than a concern, contributing genuine probiotic benefit similar to other fermented foods.

What to be aware of

  • Tempeh is safe throughout pregnancy, cooked as it normally is (fried, baked, steamed, or added to a hot dish).
  • It's a good source of protein, fibre, and iron — a useful variation on tofu for vegetarian and vegan diets specifically.
  • As with soy generally, phytoestrogen concerns aren't supported by the evidence at normal dietary intake levels.
  • Choose commercially produced tempeh from a reputable source.

What to eat instead

  • Tofu & Soy — A softer-textured, milder-tasting alternative made from soy milk rather than whole beans.

A simple way to bring out tempeh's nutty flavour, with a quick sticky glaze.

Pregnancy tip: Slice the tempeh thinly and fry until genuinely golden and crisp on both sides — this improves both texture and flavour significantly compared to a quick, pale fry.

Ingredients

  • 200g tempeh, sliced into thin strips
  • 2 tbsp vegetable oil
  • 2 tbsp soy sauce
  • 1 tbsp maple syrup or honey
  • 1 tsp fresh ginger, grated
  • 1 clove garlic, crushed
  • Sesame seeds and spring onion to serve

Method

  1. Heat the oil in a frying pan over medium-high heat.
  2. Fry the tempeh slices for 3-4 minutes per side until golden and crisp.
  3. In a small bowl, mix the soy sauce, maple syrup, ginger, and garlic.
  4. Pour the mixture over the tempeh in the pan and cook for 1-2 minutes until sticky and glazed.
  5. Serve scattered with sesame seeds and sliced spring onion.
