Italian Tuscan Swiss Chard Gnudi | Gnudi Toscani di Bietola al Burro e Salvia
Gnudi are ravioli that lost their clothes. Nudi in Tuscan dialect means naked, and these are the filling of a spinach and ricotta raviolo served without the pasta that would normally wrap it. No dough, no rolling pin, no sheet to seal. Only drained sheep ricotta, cooked greens, grated Parmigiano and egg, bound with the smallest amount of flour that will hold it, rolled into soft spheres and dropped into salted water.
That absence is what makes them difficult. A raviolo has a wall that protects the filling and forgives a wet ricotta. A gnudo has nothing. Every gram of excess moisture goes straight into the cooking water, and what comes out is either a cloud or a cloudy pot with nothing left in it. Tuscan cooks solve this by removing water patiently rather than by adding starch.
This version uses bietola, Swiss chard, rather than spinach. Chard is what grows in the Tuscan orto through the cold months, it has a deeper mineral flavour, and it holds its character against browned butter instead of vanishing into it. The sauce is burro e salvia, butter taken to the nut brown stage with whole sage leaves, and nothing else. Four ingredients, no margin for error in any of them.
Yield: 4 servings, about 24 gnudi. Prep: 45 minutes. Draining: 12 hours. Rest: 1 hour. Cook: 15 minutes. Difficulty: intermediate. Course: primo piatto. Region: Tuscany, the Casentino and the Maremma.
The Story
Gnudi belong to the Tuscan countryside rather than to any single city, and they exist because ravioli were expensive. Flour for pasta had to be bought or at least milled and accounted for, while ricotta was the byproduct of cheesemaking every family with a few sheep already had. Skipping the wrapper was not a chef's idea but arithmetic, done in farmhouse kitchens across the Casentino, the Mugello and the Maremma, wherever pecorino was made and the whey had to be used within the day.
The dish carries several names depending on which valley you stand in. In Siena they are gnudi. In the Casentino you hear malfatti, badly made, a name for their deliberately irregular shape rather than for any failure. The ingredients barely move: ricotta, greens, egg, cheese, a whisper of flour.
Sheep milk ricotta is the backbone. Tuscan pecorino production, above all in the Crete Senesi and the Maremma, yields ricotta di pecora with a sweetness and a faint gaminess cow ricotta lacks, and a firmer curd that drains better. The chard came from the garden, where it yields leaf after leaf from autumn to spring while spinach comes and goes. Butter and sage closes a dish built entirely from what the farm produced.
Ingredients
For the gnudi
Sheep milk ricotta, drained, 1 lb 2 oz (500 g) before draining
Swiss chard leaves, stems removed, 1 lb (450 g)
Parmigiano Reggiano, finely grated, 3/4 cup (75 g)
Egg yolks, large, 2
Type 00 flour, 1/4 cup (30 g), plus more for rolling
Fine sea salt, 1 tsp (6 g)
Freshly grated nutmeg, 1/4 tsp
Freshly ground black pepper, to taste
Semola rimacinata, 1/2 cup (85 g), for the resting tray
For the sage butter
Unsalted butter, cold, 6 tbsp (85 g)
Fresh sage leaves, whole, 16
Reserved gnudi cooking water, about 1/4 cup (60 ml)
For finishing
Parmigiano Reggiano, shaved or grated, 1/3 cup (35 g)
Freshly ground black pepper, to taste
Coarse sea salt, for the cooking water, 2 tbsp (30 g) per 4 quarts (4 litres)
Preparation
Step 1. Drain the ricotta overnight
This step decides everything and cannot be shortened. Set the ricotta in a fine mesh sieve lined with cheesecloth over a bowl, cover it and refrigerate for at least 12 hours. Good sheep ricotta gives up three to four tablespoons of liquid. Do not press it and do not squeeze the cloth: pressure compacts the curd into a dense paste. Gravity alone removes the water that would otherwise dissolve your gnudi in the pot.
Step 2. Cook and dry the chard
Strip the leaves off the stems and keep the stems for another dish. Blanch the leaves in salted boiling water for 2 minutes, drop them into iced water to fix the colour, then drain. Squeeze them in a clean towel, twisting until no more liquid comes out at all. Chard holds an astonishing amount of water: 1 lb (450 g) of raw leaf reduces to roughly 5 oz (140 g) of dry compact green. Chop it finely with a knife, not in a processor, which bruises the leaf.
Step 3. Build the mixture
Turn the drained ricotta into a wide bowl and break it up with a fork. Add the chopped chard, the Parmigiano, the egg yolks, salt, nutmeg and pepper, and fold with a spatula until evenly green with no streaks of white left. Only now scatter the flour over the surface and fold it in. Stop as soon as it disappears: every extra turn develops gluten and moves the texture from tender towards rubbery.
Step 4. Cook one test gnudo
Never shape two dozen dumplings on faith. Roll one walnut sized ball, dust it in flour and slip it into a small pan of gently simmering salted water. It should hold, rise within about 2 minutes and come out intact. If it spreads, fold in another tablespoon of flour and test again. If it comes out heavy and bouncy you have added too much, and the only cure is more ricotta.
Step 5. Shape and rest the gnudi
Line a tray with semola rimacinata in an even layer. With lightly floured hands take about 1 1/2 tablespoons of mixture and roll it between your palms into a ball roughly 1 1/4 inches (3 cm) across, using the lightest pressure that holds it. Set each on the semola and roll the tray so they coat all over, then leave them uncovered in the refrigerator for 1 hour. The semola pulls surface moisture outward and builds the thin dry skin the gnudo otherwise lacks.
Step 6. Bring the water to the right point
Use a wide pan, not a tall stockpot, with at least 4 quarts (4 litres) of water salted at 2 tablespoons (30 g). Bring it up and then bring it down: gnudi must never meet a rolling boil, because the turbulence tears them open. You want the surface trembling, around 195°F (90°C). Have a slotted spoon ready before a dumpling goes in, and never crowd the pan beyond eight.
Step 7. Brown the butter with the sage
While the water settles, put the cold butter into a wide sauté pan over medium heat with the whole sage leaves. Let it melt, foam and then quieten, swirling the pan rather than stirring. In about 4 minutes the milk solids turn hazelnut brown and the smell changes from dairy to toasted nut. Take it off the heat there, roughly 30 seconds before it would burn. The sage should be crisp and still green, not black.
Step 8. Cook the gnudi and emulsify
Slide the gnudi into the trembling water one at a time. They sink, rise after about 2 minutes, and need 1 minute more. Lift them out draining well and add them to the brown butter off the heat. Add 2 or 3 tablespoons of cooking water, return the pan to low heat and swirl, never stir, until butter and starchy water come together into a glossy sauce that clings. Serve at once.
Plating
Warm the plates to around 140°F (60°C). Gnudi are mostly fresh cheese and lose heat faster than any pasta, and butter that hits a cold plate sets into a dull film. A shallow bowl with a flat base beats a rimmed plate, holding the sauce in a pool where the dumplings sit.
Six gnudi per person is a serving. Place them with a spoon, leaving space between each so they read as individual dumplings. Spoon the emulsified butter over and around them, then lay two or three crisp sage leaves on top, where they stay dry rather than sinking.
Finish with Parmigiano shaved in wide flakes with a peeler rather than grated to dust, so it softens slowly instead of dissolving, and one turn of black pepper. Nothing else: no cream, no tomato, no parsley. The dish is pale green and gold and should look like four ingredients.
Professional Technique
The governing technique of gnudi is water removal by three separate routes, none of which substitutes for the others. The ricotta loses whey to gravity. The chard loses its water by force, in a towel. The shaped dumplings lose surface moisture to the semola. Skipping any one leaves the mixture needing more flour, the single thing that ruins the texture. Flour is not the binder in a good gnudo. Drained curd, egg yolk and grated hard cheese are.
The semola rest does real work. Durum semola is coarse and thirsty, and an hour of contact draws moisture from the outer two millimetres and leaves a thin dehydrated layer behind. When that layer meets hot water its starch gelatinises almost instantly and forms a skin. It is the closest thing a naked dumpling has to a wrapper, and it is why carefully made gnudi survive the pot while rushed ones do not.
Browning butter is a controlled Maillard reaction on milk solids, not simply melting. Cold butter is deliberate: it melts slowly and gives its water time to evaporate before the solids colour, producing an even hazelnut brown instead of scorched flecks. The sage goes in at the start, while the butter is still cool, so the leaves fry gently and arrive crisp exactly when the butter is ready. Sage thrown into already brown butter turns black in seconds.
Texture and Moisture Control
You are aiming for a dumpling that yields completely to the side of a fork and tastes of ricotta rather than flour. That depends on a ratio: roughly 1/4 cup (30 g) of flour for 1 lb 2 oz (500 g) of ricotta, far less than most versions use. It works only if the ricotta and the chard have genuinely been dried. A wet mixture demands double the flour and turns bouncy and pasty.
Temperature in the pot matters as much as the mixture. At a rolling boil the mechanical action alone opens the dumplings. At 195°F (90°C) the yolk proteins set gently through the ball while the surface starch seals, and the gnudo cooks from the outside in without being knocked about. A gnudo floats when the interior has expanded and set, and 1 further minute finishes it. Beyond that it leaks ricotta into the water.
The final emulsion is pure physics. Brown butter alone is fat, and fat slides off a dumpling and pools on the plate. Two or three tablespoons of cooking water bring dissolved starch and salt, and swirling them into the butter off direct heat disperses that water into droplets held in the fat, giving a sauce with body that coats. Add it while the pan is fiercely hot and it boils away. Add too much and the sauce turns watery.

Chef Tips
Buy ricotta from a cheesemaker rather than a supermarket tub. Industrial ricotta is stabilised, often with added gums, and holds its water instead of releasing it, so twelve hours of draining gives you almost nothing. Ricotta di pecora from a Tuscan dairy drains freely and tastes sweet and faintly grassy, and it is the whole flavour of this dish.
Weigh the chard after wringing, not before. Raw weight is a guess, because how much water you remove varies with the leaf and how hard you twist. Aim for about 5 oz (140 g) of squeezed green from 1 lb (450 g) of raw leaves, and if you hold more, wring it again in a dry towel.
Use only the yolks. The white is close to 90 percent water and adds exactly the moisture you spent a day removing, and it sets firm and springy. Two yolks carry enough lecithin to bind and enough fat to keep the mixture tender.
If you cannot serve the shaped gnudi within 3 hours, freeze them on the semola tray rather than holding them longer in the refrigerator, where they slowly weep. Frozen solid and bagged, they cook straight from frozen in about 5 minutes and lose very little.
Common Mistakes
Skipping the overnight drain. The most common failure, and it has no workaround. Undrained ricotta releases whey into the mixture, the mixture then needs flour to hold, and the flour makes the gnudi heavy. Twelve hours in a sieve costs no work, only planning.
Boiling the water hard. A rolling boil tears these dumplings apart and no amount of flour saves them. Bring the water to the boil to dissolve the salt, then drop the heat until the surface only trembles and keep it there through the service.
Using a food processor on the mixture. Blitzing the ricotta breaks the curd and turns a light mixture into a wet paste that needs far more flour. Fold by hand with a spatula and stop the moment the flour disappears.
Browning the butter too far. Between hazelnut and burnt there are about 30 seconds. Past deep brown the butter turns acrid and there is no correcting it. Pull the pan off while it still smells of toasted nuts, remembering it keeps cooking in the residual heat.
Wine Pairing
Vernaccia di San Gimignano DOCG: The most natural white for this plate, and a Tuscan one. Its firm acidity cuts through the brown butter, the only real fat on the table, and stops the dish feeling rich by the third gnudo. The slightly bitter almond finish runs alongside the mineral edge of the chard rather than covering it, and a good bottle has the texture to stand beside the ricotta.
Chianti Rufina DOCG: From the cooler hills northeast of Florence, the most elegant Sangiovese for a delicate primo. The tannin is fine and the acidity high, so the wine refreshes rather than grips, and its sour cherry fruit answers the savoury Parmigiano. Serve it at around 61°F (16°C): poured warm it turns heavy and buries a dish this quiet.
Rosso di Montalcino DOC: The younger sibling of Brunello and a far better match here than Brunello itself, which would bury the plate. It brings ripe red fruit and a gentle earthiness that picks up the sage without competing, and tannins soft enough not to clash with fresh sheep cheese, which turns metallic against anything aggressively structured.
Carmignano DOCG: Sangiovese blended with a little Cabernet, grown west of Florence, and the choice when you want more weight on the table. The Cabernet adds a herbal leafy note that meets the sage and the chard on their own ground, while the Sangiovese acidity keeps the butter in check. Choose a young bottling rather than a riserva so the oak stays out of the way.
Storage & Reheating
Gnudi are best within minutes of leaving the water, so store them raw rather than cooked. Shaped uncooked gnudi keep on their semola tray, uncovered in the refrigerator, for up to 3 hours, after which they weep. For longer, freeze them on the tray in a single layer until solid, about 2 hours, then bag them and keep for up to 1 month.
Cook frozen gnudi straight from the freezer, never thawed, since thawing turns them into a puddle. Drop them into water at 195°F (90°C) for about 5 minutes, 2 minutes longer than fresh, watching for the same rise followed by a further minute. The texture is very close to fresh.
Cooked leftovers keep refrigerated in a sealed container for 2 days, covered in their butter. Do not reheat them in water, which waterlogs them, and do not microwave them, which turns the ricotta grainy. Warm them in a covered sauté pan over low heat with a tablespoon of butter and a splash of water for about 4 minutes. Cooked gnudi do not freeze: the ricotta separates on thawing.
