Why is my risotto still crunchy in the middle?
Cold stock, an acidic addition too early, the wrong rice or simply not enough time — the four causes, how to tell them apart and how to finish the pan you have.

Short answer
Keep adding hot stock a ladle at a time and keep going — most crunchy risotto is simply not finished, and it needs 18–25 minutes of active cooking, not the 15 most recipes state. If it has stopped softening altogether, the stock is going in cold, or you added wine, tomato or lemon before the grain was cooked through.
Risotto rice has a hard starchy core that is meant to stay slightly firm — that is what al dente means here — but there is a clear difference between a grain with a pleasant firm centre and one with a chalky white spot that grits between your teeth. The second one is undercooked and it is fixable.
Step by step
- Test properly before you diagnose.Take a few grains and bite through. A done grain is tender all the way with just a firm centre and no visible white core in the middle when you look at the cut face. A chalky opaque dot is undercooked.
- Check the stock is genuinely hot.This is the most common cause. Cold or lukewarm stock drops the pan temperature every time you add a ladle, so the rice spends much of its time below cooking temperature. Keep the stock at a bare simmer in a separate pan alongside and take it from there.
- Just keep going.Add another ladle of hot stock, stir until absorbed, taste, repeat. A risotto is done when it is done, not when the recipe says. Older rice, a wide pan and a low hob all push the time out. Twenty-five minutes is not unusual.
- Check what acid went in and when.Wine is added early and evaporates, which is fine. Lemon juice, tomato, vinegar or a very acidic stock added while the grain is still hard will stop the starch softening in the same way acid stops a potato softening. If that is what happened, add plain hot water rather than more stock to dilute, and expect it to take longer.
- Check the rice.Arborio, carnaroli or vialone nano. Carnaroli is the most forgiving because it holds its shape over a wider window. Long grain, basmati or pudding rice will never behave like risotto rice. Rice that has been in the cupboard for years also softens reluctantly.
- Check the heat and the liquid level.The pan should be at a lively simmer, not a bare one, and the rice should never be dry — it wants to be loose and moving, with liquid just level with the grains. A pan run too dry between ladles stops cooking.
- Finish it off the heat.When it is nearly there, take it off, beat in cold butter and grated parmesan, cover and leave two minutes. That rest evens out the moisture and finishes the last of the softening — the mantecatura. Serve it loose enough to spread slowly on the plate.
Tips
- Toasting the dry rice in the fat for a minute or two before any liquid — the tostatura — helps the grain hold its shape but does not slow softening.
- You can par-cook risotto to about two-thirds, spread it on a tray to cool fast, and finish it to order later. That is how restaurants serve it in ten minutes.
- Constant stirring is not actually required. What is required is enough stirring to keep the grains moving against each other and releasing starch — every minute or so is plenty.
If it doesn't work
Chalky white core in the grains after 20 minutes
Cause: Stock too cool, or heat too low — Fix: Get the stock properly hot, raise the hob to a lively simmer and keep adding.
Stopped softening entirely however much stock goes in
Cause: Acid added too early — lemon, tomato or a very acidic wine — Fix: Add plain hot water to dilute and allow considerably longer.
Soupy but the grains are still hard
Cause: Too much liquid at once, so it is boiling rather than absorbing — Fix: Raise the heat to drive off the excess and go back to one ladle at a time.
Grains soft outside, hard inside, and the risotto is stodgy
Cause: Not enough liquid and too much stirring against a dry pan — Fix: Loosen with hot stock. Keep the pan loose throughout rather than letting it tighten between additions.
Questions people ask
How firm should the centre of the grain be?
There should be resistance but no chalkiness. If you can see a distinct white dot in the cut grain it is undercooked; if the grain has collapsed and lost its shape it has gone too far.
Can I use water instead of stock?
Yes, and hot water plus properly seasoned aromatics beats a weak cold stock cube every time. The temperature matters more than the ingredient.
