Are you passionate about seitan? This is a popular vegan food that is much enjoyed by individuals all over the world, but sometimes, its texture isn’t amazing. You might end up with a seitan that is spongy or heavy, and that’s not something anyone enjoys.
Seitan can be spongy for a range of reasons, but the commonest problem lies in over-kneading the dough. Not simmering the seitan correctly can also be an issue, and taking it out of the water too quickly may make it spongy on the outside. Most seitan will be denser and nicer if left for a day before it is consumed.
We’re going to find out the top reasons that seitan becomes spongy so you know how to avoid this issue and make sure your seitan tastes great. This is a versatile and cruelty-free food, so it’s important to know how to make it well!
What Makes Seitan Spongy?

There are a few things that can make your seitan feel spongy, rather than chewy and satisfying. These include:
- Kneading the dough for too long
- Boiling the seitan rather than simmering it
- Not letting the seitan rest in the water
- Eating the seitan as soon as it has been made
Any or all of these could be contributing to your seitan tasting spongy, so let’s find out how you can address them and give your seitan a much better texture!
Reason 1) Kneading The Dough For Too Long
This is the biggest problem that people generally run into when they are making seitan at home. You’re making a dough, and if you knead a dough too heavily or for too long, it will become chewy or even spongy. Kneading introduces air, after all, and having a lot of air in your seitan will produce this unpleasant texture.
When you knead the dough, you develop the gluten in it; this is sometimes known as “activating” the gluten. It combines the long proteins with the water, increasing the strength of the bonds and creating more and more structure. The more you mix gluten, the more elastic it becomes, and the chewier you will make your seitan.
You need to knead your seitan both gently and for a short period. Many recipes recommend between 2 and 3 minutes of kneading. If you stick with one recipe and you find it’s too spongy the first time you make it, you can do less kneading next time.
Reason 2) Boiling The Seitan
You may already be aware that you should simmer your seitan, rather than boil it, but you might not take this as seriously as you should. The ideal setup is with just a few very small bubbles rising to the surface and no obvious surface disturbance at all.
You should still boil the broth to start with, but make sure it’s on a gentle simmer before you add the seitan. If your water is boiling hard, the bubbles rising to the surface will make holes in the dough. This literally creates a spongy, holey texture that most people find unappealing. Do not let the water boil.
Reason 3) Not Letting The Seitan Rest
When you’ve finished cooking the seitan, you should turn the heat off, but don’t lift it straight out of the water. Seitan needs to be simmered for an hour and then rested for about 15 minutes. This allows it to start gently cooling, rather than being shocked by being lifted into cold air straight away.
If you lift the seitan out, the cold air will affect the outside of the seitan and will make the outer layer spongy. To avoid this, let it cool in the pan for a short while first, and then lift it out and leave it to continue cooling. You’ll retain the meaty texture throughout the meal if you do this.
Reason 4) Eating The Seitan Too Soon
You might be tempted to serve your seitan as soon as it is cooked, but it won’t be at its best at this point. Storing it for a full 24 hours before you consume it is a great way to ensure that it tastes as good as it can. If you don’t store the seitan, there will still be quite a lot of water in it.
Letting it rest gives the water time to evaporate, and will maximize its flavor and texture. It will become denser and more like meat – perfect for vegans who are missing that chewy texture.
Conclusion
If you keep ending up with stodgy and spongy seitan, it’s probably for one of these 4 reasons – so hopefully you now know how to change your approach to solve the problem. Well-cooked seitan is a delightful experience for everyone, so take the time to check each of these steps and resolve any issues with them.
