Risotto alle ortiche is a Northern Italian spring nettle risotto: young stinging nettles are blanched, puréed, and stirred into Carnaroli rice in the last 2 minutes of cooking. The result is silky and vivid green, with an earthy flavor that sits between spinach and green tea.
Wear gloves to handle raw nettles. Their stinging hairs release irritants on contact with skin, and 2 minutes in boiling water deactivates them. Load the pot with tongs, and once the leaves are blanched they’re safe to touch and eat.
The method is classic: soffritto, tostatura, then ladle-by-ladle cottura. The purée goes in last because early heat turns the color khaki.
Plan on about 53 minutes, most of it at the stove, stirring.

Ingredient Notes
- Stinging nettles: Use the top four to six leaves of young plants picked before they flower. Wear gloves until they’re blanched. Practical pantry note: frozen nettles work year-round (see FAQ for amounts).
- Carnaroli rice: Carnaroli holds its shape and releases starch slowly, which gives a creamy risotto with a firm center. Arborio works, but cook it a minute or two less and watch it closely.
- Vegetable broth: Choose a light, low-salt broth so it doesn’t mask the nettles. Homemade is best, but a good bouillon cube in 1.2 L of water is fine. Taste before salting, since Parmigiano adds more.
- Parmigiano Reggiano: Grate it finely so it melts into the rice in seconds. Grana Padano is a cheaper swap with a slightly milder, sweeter flavor.
- Dry white wine: Pick an unoaked, crisp white such as Soave or Verdicchio. If you’d rather skip alcohol, use 120 ml extra broth plus 1 tsp more lemon juice.
- Lemon: The zest brightens the earthy greens without making the risotto taste sour. Add the juice at the very end so it stays fresh.
Risotto alle Ortiche with Spring Nettles and Parmigiano
Ingredients
Method
- Put on dishwashing gloves. Bring 2 L / 2 quarts of water and 1 tbsp salt to a boil in a 4-quart / 3.8 L pot and set a bowl of ice water beside the stove. Use tongs to push the nettles into the water and blanch for 2 minutes, until deep green and limp.
- Lift the nettles into the ice water with tongs and chill for 1 minute. Drain, then squeeze them hard in a clean kitchen towel. Blend with 80 ml cold water for 1 to 2 minutes until smooth and vivid green. You'll have about 200 g purée.
- Bring the broth to a bare simmer in a 3-quart / 2.8 L saucepan and keep it hot on the lowest heat. In a 28 cm / 11-inch straight-sided sauté pan, warm the olive oil over medium-low heat. Add the onion and a pinch of salt and cook for 7 minutes, stirring, until soft and translucent with no browning.
- Raise the heat to medium, add the rice, and toast for 2 minutes, stirring, until the edges turn translucent and the grains smell nutty. Pour in the wine and stir for about 1 minute until it has evaporated and the pan looks nearly dry.
- Add the hot broth one ladle (about 120 ml) at a time, stirring often and waiting until each addition is mostly absorbed before adding the next. Keep a lively simmer and continue for 16 minutes. You'll use about 1 L of the broth.
- At minute 16, stir in the nettle purée with the next ladle of broth and cook for 2 more minutes, until the rice is al dente: tender outside, slightly firm at the center, with no chalky dot. Don't add the purée earlier, since long heat turns it khaki.
- Take the pan off the heat. Add the cold butter, Parmigiano, lemon zest, and lemon juice, then stir hard for 30 seconds until glossy. The risotto should spread slowly across a plate in a wave (all'onda), so loosen it with a splash of hot broth if it stands in a mound. Season with salt and pepper and serve right away in warm bowls.
Notes
- Weigh nettles after trimming thick stems. 200 g raw tops gives roughly 120 g once blanched and squeezed.
- Salt the blanching water, since it seasons the nettles and helps keep the green bright.
- Taste the rice at minute 16. It should be tender outside with a slight firmness at the center.
- Loosen the finished risotto with a splash of hot broth if it stands in a mound instead of flowing.
Tips for Success
- Wear dishwashing gloves and use tongs when washing and loading raw nettles, and pick only the top four to six leaves of young plants.
- Keep the broth at a bare simmer in a separate pan so every ladle goes in hot and the rice never stalls.
- Squeeze the blanched nettles hard in a clean towel, because leftover water thins the purée and loosens the risotto.
- Stir the rice often but not constantly, and add the next ladle only when the spoon leaves a clear trail across the pan bottom.
- Finish off the heat with cold butter and Parmigiano, then stir hard for 30 seconds until the risotto flows slowly across a plate.
Variations
- Fold in 150 g fresh goat cheese at the end instead of the butter for a tangier, looser risotto.
- Top each bowl with a soft poached egg and a spoonful of toasted breadcrumbs for a runny yolk and some crunch.
- Skip the wine and use 120 ml extra broth plus 1 tsp more lemon juice for an alcohol-free version.
Storage and Reheating
Leftover risotto alle ortiche keeps 2 days in the fridge in a shallow airtight container. Cool it for no more than 1 hour first, because cooked rice held at room temperature can grow Bacillus cereus, and reheating won’t destroy its toxin.
Reheat in a 24 cm / 10-inch nonstick skillet over medium-low heat with 3 tbsp of broth or water per portion. Stir for 4 to 5 minutes until it’s steaming hot, at least 165 F / 74 C throughout. A small knob of butter and a spoonful of grated Parmigiano bring back the creaminess.
The nettle purée is the make-ahead part. Refrigerate it in a jar for 3 days, or freeze it in ice cube trays for up to 3 months. Thaw a few cubes and stir them in during the last 2 minutes of cooking.
Serving Suggestions
Serve risotto alle ortiche right away in warm shallow bowls, because the rice keeps absorbing liquid and tightens as it sits. Tap the bowl on the counter and the risotto should settle into a gentle wave.
Finish with a little extra Parmigiano, a few turns of black pepper, and a pinch of lemon zest. A thin drizzle of good olive oil works well too.
As a primo, follow it with pan-seared scallops, roast chicken, or a simple frittata. For a light lunch, add a salad of arugula dressed with lemon and olive oil, and pour a cold Soave or Verdicchio.
FAQ
Why did my nettle risotto turn dull olive green instead of bright green?
Heat and time dull the color. Blanch the nettles for just 2 minutes, chill them in ice water, and stir the purée into the rice only for the last 2 minutes of cooking. If the purée simmers in the pan for 10 minutes or more, the risotto turns khaki, though the flavor stays good.
Can I use spinach or frozen nettles instead of fresh stinging nettles?
Yes. Use 150 g thawed, well-squeezed frozen nettles and skip the blanching, or 200 g baby spinach wilted in the boiling water for 1 minute. Spinach is milder and sweeter, so add the lemon zest and a little extra black pepper to bring back the earthy edge.
Can I make nettle risotto ahead, or freeze the nettle purée?
Freeze the purée, not the risotto. Nettle purée keeps 3 months in ice cube trays and thaws in minutes, so one spring harvest covers several dinners. The risotto itself is best cooked fresh, and leftovers keep 2 days in the fridge.
What wine goes with nettle risotto?
A dry, unoaked white with good acidity, such as Soave or Verdicchio, suits the earthy greens and lemon zest. Cook with the same bottle you pour. Pan-seared scallops or lemon roast chicken make good next courses because they don’t compete with the nettles.
Is risotto alle ortiche gluten free, and can I make it vegan?
Yes, it’s gluten free as long as your broth is, since the rice, nettles, and Parmigiano contain no gluten. Check the broth label. For a vegan version, use 2 tbsp olive oil instead of the butter, replace the cheese with 3 tbsp nutritional yeast, and season with extra salt at the end.
What’s the difference between risotto alle ortiche and spinach risotto?
Nettles taste earthier and slightly mineral, with a faint peppery edge, while spinach is mild and sweet. Nettles also need blanching to remove the sting. Risotto alle ortiche is a spring dish in much of Northern Italy, made with young tops, while spinach risotto is a year-round supermarket dish.
