How to Make Lentil Tofu (Step by Step)

Making lentil tofu is quick and uncomplicated, and the whole process uses one blender and one pot. Here’s exactly how to get the perfect smooth, firm texture every time.

1. Soak the lentils

Add the lentils to a bowl or straight into your blender jug, then cover them with boiling water. Let them soak for about 20 minutes until they soften and absorb some of the liquid. This helps them blend ultra smooth without any gritty texture.

2. Blend until completely smooth

Blend the soaked lentils and water on high speed until the mixture is silky with no visible pieces. A smooth blend is the key to a tofu that sets evenly and doesn’t crumble.

3. Cook the mixture until thick

Pour the blended mixture into a pot, add the warm water, and cook over medium to medium high heat. Whisk continuously for 8 to 10 minutes until it thickens into a glossy, porridge-like consistency. Don’t stop whisking here — it prevents lumps and ensures the tofu sets properly.

4. Transfer and chill

Spread the thickened mixture into a shallow container or baking dish and level the top. Refrigerate for at least 4 hours. It will firm up as it cools, and the longer it sits, the stronger the structure becomes.

5. Drain and use

Once fully set, pour off any liquid that has separated, then slice or cube the tofu. It’s ready to stir fry, bake, air fry or add straight into bowls, curries or salads.

Tips for Perfect Lentil Tofu

• Blend until silky – If the mixture isn’t completely smooth, the tofu can set with grainy bits. Blend longer than you think.
• Whisk constantly – This stops lumps forming and helps it thicken evenly.
• Cook until very thick – It should look like glossy porridge before you pour it into the container. If it’s too runny, it won’t firm properly.
• Chill long enough – Minimum 4 hours. Overnight gives the firmest texture.
• Choose the right container – A shallow dish sets faster and makes it easier to slice cleanly.
• Adjust water for texture – Less water = firmer tofu. More water = softer, more custard-like tofu.
• Drain before using – It naturally releases a small amount of water as it sets. Pour this off before slicing.

Troubleshooting

It didn’t set

This usually means it wasn’t cooked long enough. Next time, keep whisking until it becomes thick and glossy before chilling.

It’s too soft

Reduce the water slightly or chill it overnight. Softer tofu still cooks well but won’t hold sharp edges.

It’s too firm

Add a little more warm water when cooking next time. Lentils absorb water differently batch to batch.

It’s grainy

The mixture wasn’t blended smooth enough. Blend longer or blend in two batches if your blender is small.

It tastes bland

Season the cooking mixture with salt, garlic powder, onion powder, curry powder or nutritional yeast.

Storage and Meal Prep

• Store in an airtight container in the fridge for up to 3 days.
• For meal prep, slice into cubes and keep them ready to fry or air fry.
• Avoid freezing — the texture becomes crumbly once thawed.
• If excess water forms in the container, just pour it out before cooking.
