Mushrooms carry natural glutamates, the same compound behind umami flavor in general, which is why a mushroom-heavy dish can taste deeply savory without leaning on salt to get there.
Soaking dried porcini mushrooms and using the soaking liquid in place of some of the broth doubles down on that mushroom flavor at no extra sodium cost.

A Short History
Risotto developed in northern Italy, particularly the Po Valley region around Lombardy and Piedmont, where rice paddies flourished starting in the fifteenth century after rice cultivation arrived from Spain and the Middle East. Unlike the drier, separate-grain rice dishes of the Mediterranean's south, northern Italian cooks embraced a starchier short grain rice and a slow, stirred cooking method that released that starch on purpose.
Mushroom risotto specifically, risotto ai funghi, became one of the most common regional variations because wild mushrooms, especially porcini, grow abundantly in the forests of northern Italy and were a free, seasonal way to add deep flavor to a simple rice and broth base. Dried porcini, which concentrate that flavor and keep year round, became the pantry shortcut that lets the dish be made any time of year.
The Four Components
- Protein. Parmesan, stirred in at the end.
- Starch. Arborio rice, the classic risotto grain.
- Vegetable. Cremini mushrooms and dried porcini.
- Sauce. The rice's own starch, released while stirring.
Choosing the Mushrooms
For the cremini, look for firm, dry caps without dark soft spots, and slice them just before cooking since cut mushrooms lose moisture and flavor quickly sitting in the fridge. Wipe them clean with a damp towel rather than rinsing under water, which mushrooms absorb readily and which then steams out in the pan instead of browning.
For the dried porcini, buy from a source with good turnover; older dried mushrooms can taste musty rather than deeply savory. Check the porcini after soaking for any grit that has settled at the bottom of the soaking liquid, and pour the liquid off carefully, leaving the last bit behind, so no sediment ends up in the finished risotto.
The Technique That Makes It: Building Starch Through Stirring
Risotto's creaminess does not come from cream. It comes from arborio rice's high amylopectin starch content, which releases into the cooking liquid as the grains rub against each other and against the pot. Frequent stirring is what causes that friction; a risotto left alone like a pot of plain rice will cook through but never develop the same body.
Adding the broth gradually, one ladle at a time, matters just as much as the stirring. Each addition should mostly absorb before the next goes in, which keeps the rice cooking at a steady simmer rather than boiling or drowning, and gives the starch time to release into a concentrated liquid instead of a thin one. The goal at the end is a risotto that is loose enough to spread slightly when spooned onto a plate, often called all'onda, wave-like, rather than a stiff mound.
Low-Sodium Mushroom Risotto
Serves four. Prep fifteen minutes, cook thirty five minutes, total about fifty minutes.
Ingredients
Protein
- 1/3 cup parmesan, grated
Starch
- 1 1/2 cups arborio rice
Vegetable
- 1 ounce dried porcini mushrooms
- 8 ounces cremini mushrooms, sliced
- 1 onion, finely diced
Sauce
- 2 cups hot water
- 2 tablespoons olive oil
- 1/2 cup dry white wine
- 4 cups low-sodium vegetable broth, warm
- Black pepper, to taste
Method
Mise en place
- Soak the dried porcini in the hot water for 15 minutes. Strain, reserving the liquid, and chop the mushrooms.
Building the base
- Heat the olive oil in a wide pot and cook the cremini mushrooms until browned, about 6 minutes. Add the onion and cook 4 minutes more.
- Add the rice and toast 1 minute, then add the wine and stir until absorbed. Add the porcini liquid and chopped porcini.
The stir and simmer
- Add the warm broth one ladle at a time, stirring frequently and waiting for each addition to absorb before adding more, about 20 minutes total, until the rice is creamy and just tender.
Finish
- Stir in the parmesan and black pepper off the heat, and serve immediately while the risotto is loose and glossy.
Doneness
The rice is done when each grain is tender but still has a very slight bite at the center, never fully soft, and the risotto spreads slowly into a wave when spooned onto a plate rather than holding a stiff mound.

Get Ahead: A Timing Plan
- Up to a day ahead: soak the porcini and slice the cremini mushrooms.
- While it cooks: stay near the pot; risotto needs frequent stirring and attention.
- Last step: stir in the parmesan off the heat so the risotto stays creamy, not gluey.
Wine Pairing
The earthy mushroom flavor and the wine already in the dish call for a similar white or light red with its own earthiness.
- Pinot Grigio from Alto Adige gives a clean, mineral backdrop that doesn't compete with the mushrooms.
- White Burgundy or another Chardonnay adds enough body to stand up to the parmesan.
- Pinot Noir for a light, earthy red that mirrors the porcini's own flavor.
Building the Meal Around It
Serve as a starter or main, or alongside Herb-Crusted Rack of Lamb. A simply dressed arugula salad with lemon cuts through the richness if serving it as a main course.
Cooking for a Crowd
Risotto famously does not hold well made fully ahead, but it can be par cooked: stop adding broth about two thirds of the way through, spread the rice on a sheet pan to cool quickly, and finish it with the remaining broth just before serving. For a crowd, this par cooking step is worth doing since finishing a large batch entirely to order at the stove is hard to manage alongside everything else on the menu.
Troubleshooting
- Risotto turns gluey. The parmesan was added over heat, or the rice was overcooked. Stir it in off the heat and check doneness earlier.
- Rice stays hard in the center. Not enough broth was added, or it was added too fast without absorbing. Slow down and give each addition time.
- Risotto is too soupy. Too much broth went in at once near the end. Let it simmer a few more minutes uncovered to reduce.
- Bland despite the porcini. The soaking liquid was discarded instead of used, losing the concentrated mushroom flavor. Always cook with the strained soaking liquid.
Variations
- All fresh mushroom. Skip the dried porcini and use a mix of fresh wild mushrooms if available.
- Barley risotto. Substitute pearled barley for the arborio for a chewier, nuttier texture.
- Add peas. Stir in a cup of frozen peas during the last few minutes of cooking for color and sweetness.
- Truffle finish. A few drops of truffle oil stirred in at the end intensifies the earthy flavor further.
Frequently Asked Questions
Can I skip the dried porcini?
You can, but they add a concentrated mushroom flavor that fresh mushrooms alone don't provide as strongly.
Why arborio rice specifically?
Its high starch content is what gives risotto its signature creamy texture without any cream added.
Can I make risotto without wine?
Yes, substitute an equal amount of extra broth or a splash of white grape juice with a squeeze of lemon for acidity.
Do I have to stir constantly?
Frequent stirring, not constant, is what matters; stir every minute or so and let it simmer quietly in between.
Can I use a different cheese instead of parmesan?
Yes, pecorino romano or grana padano both work, though pecorino is saltier so use a little less.
Why did my risotto turn out clumpy instead of creamy?
The rice likely wasn't stirred enough to release its starch, or too much broth was added at once. Stir often and add broth gradually.
