Italian Grilled Polenta with Wild Mushroom Ragù, Black Truffle and Aged Taleggio | Polenta Grigliata con Ragù di Funghi Selvatici, Tartufo Nero e Taleggio Stagionato
Grilled polenta is the second life of a dish that was never meant to have one. In the corn eating north of Italy a pot of polenta fed a household for two days, and what set overnight in a wooden bowl was never thrown away. It was turned out, cut into slabs and laid onto the embers, where the outside dried and blistered while the inside stayed soft. That transformation is the point of this recipe, and it cannot be faked in a pan.
What goes on top is of the same mountains. A ragu of mixed wild mushrooms, built so the fungi release and then reabsorb their own liquid, holds together with almost no tomato and no cream. Aged Taleggio goes on while the polenta is hot enough to soften it without melting it into a sauce, and black truffle is shaved at the table, where its aromatics still have somewhere to go.
Yield: 4 servings. Prep: 30 minutes. Cook: 1 hour. Rest: 6 hours or overnight for the polenta. Total: about 7 hours 30 minutes, most of it unattended. Difficulty: intermediate. Course: primo piatto. Region: Veneto, Lombardy and the Alpine arc.
The Story
Polenta arrived in northern Italy with maize from the Americas in the sixteenth century, and within two hundred years it had displaced almost every other grain between the Po and the Alps. In Veneto, Lombardy, Trentino and Friuli it was not a side dish, it was the meal. A copper paiolo hung over the fire, the cornmeal went in with salted water, and someone stirred it for the best part of an hour. What came out was poured onto a board, cut with a length of string and eaten with whatever the season allowed.
The grilling came from thrift. Cooled polenta sets into a firm block that slices clean, and a slice laid on the embers developed a crust that fresh polenta never has. In Friuli the fogolar, the open hearth of the old farmhouses, kept embers alive all day for exactly this. It was poverty food that happened to taste better than the version it came from.
The topping places the dish. Wild mushrooms belong to the chestnut and beech woods of the foothills from Bergamo to Belluno, where the autumn hunt for porcini, chiodini and finferli is still a local obsession. Taleggio comes from the Val Taleggio above Bergamo, made there since the tenth century and aged in the damp caves of the Valsassina. Black truffle completes it: not the white truffle of Alba, which would be wrong here, but the darker winter truffle of the northern Apennines.

Preparation
Step 1: Cook the polenta stiff, not soft
Boil the water with the salt in a heavy pot. Rain the cornmeal in with one hand while whisking with the other so no lumps form, drop the heat until the surface only blips, and cook 45 to 50 minutes, stirring often and scraping the bottom. The ratio is 5 parts liquid to 1 part meal, stiffer than creamy polenta, because this batch must set hard enough to slice.
Step 2: Enrich it and set it overnight
When the polenta pulls away from the sides in a mass, beat in the butter and the Grana Padano and check the salt. Pour it onto an oiled sheet tray and spread it to an even 3/4 inch (2 cm) with a wet offset spatula. Even thickness matters: a thinner end chars before the thick end warms through. Cool uncovered, then refrigerate at least 6 hours, preferably overnight.
Step 3: Rehydrate the dried porcini and keep the liquid
Cover the dried porcini with the warm water for 20 minutes, lift them out, squeeze them lightly and chop them fine. Pour the soaking liquid through a fine mesh sieve lined with a damp paper towel, stopping before the last spoonful, which carries grit. That liquid is the strongest mushroom flavour here and goes into the ragu.
Step 4: Clean the fresh mushrooms without water
Brush the porcini and the wild mushrooms or wipe them with a barely damp cloth, and trim the stem bases. Do not rinse them: mushrooms are mostly water already, and a rinse pushes more in, so they steam instead of browning. Cut the porcini into thick wedges through the stem, and leave the small mushrooms whole.
Step 5: Sear the mushrooms in batches
Heat a wide sauté pan over high heat with 2 tablespoons of the olive oil until it shimmers. Add the porcini in one uncrowded layer, leave them 2 minutes, turn them and give them a minute more. Move them to a plate and repeat with the mixed mushrooms. Two or three batches is normal: a crowded pan simply steams.
Step 6: Build the base and return the mushrooms
Lower the heat, add the rest of the oil and the butter, and cook the shallot with the crushed garlic and a pinch of salt for 6 to 7 minutes until soft but not coloured. Stir in the tomato paste and let it darken for a minute. Add the chopped porcini, then the wine, and reduce almost completely. Return the seared mushrooms with the thyme, bay leaf and pepper.
Step 7: Braise the ragu until it binds
Pour in the strained porcini liquid, bring to a bare simmer and cook uncovered 20 to 25 minutes over low heat. The mushrooms release liquid, then slowly take it back. It is ready when a spoon dragged across the pan leaves a track that closes slowly. Remove the garlic, bay leaf and thyme, and check the salt now, because the cheese brings its own.
Step 8: Cut and dry the polenta slabs
Turn the set polenta onto a board and cut eight rectangles of about 3 by 2 inches (8 by 5 cm). Pat every surface dry with a clean cloth and leave the pieces uncovered on a rack for 15 minutes while the grill heats. Surface moisture is the one reason grilled polenta sticks and tears.
Step 9: Grill the polenta
Heat a cast iron grill pan or a charcoal grill until a drop of water bounces and vanishes. Brush the polenta lightly with olive oil, not the grate, and lay the pieces at a slight angle. Leave them alone for 4 to 5 minutes: they release themselves once the crust has formed, and lifting them early takes half the slab with it. Turn once, grill 3 to 4 minutes more.
Step 10: Dress the cheese and shave the truffle last
Lay the thin Taleggio slices over the hot polenta the moment it leaves the grill and let the residual heat work for a minute, until the edges slump and go glossy while the centres hold. Warm the ragu to just under a simmer, spoon it over, then shave the truffle at the table and finish with parsley, olive oil and flaky salt.
Plating
Warm the plates properly. This is one of the few dishes on which a cold plate is immediately obvious, because the crust softens from underneath and the Taleggio stiffens again within a minute. Hold them at around 140°F (60°C).
Set two slabs per plate, overlapping slightly, with the grill marks running the same way on both. Spoon the ragu across the join so it falls partly on the polenta and partly onto the plate, letting a few whole porcini wedges sit proud. A ragu that covers the polenta completely hides the crust you spent the recipe building.
Shave the truffle over the plate in front of the diner if you can. Finish with parsley, a thin drizzle of olive oil around the outside and flaky salt on the exposed crust. Nothing else belongs here. The colours are brown on brown, exactly as the dish looks in the mountains it comes from.
Professional Technique
The defining technique is the deliberate dehydration of a cooked starch before it meets direct heat. Polenta straight from the pot is roughly eighty percent water and will never grill: it steams, sags and welds itself to the grate. Setting it overnight does two things. The starch granules that gelatinised during cooking retrograde as they cool into a firmer network that holds a cut edge, and the surface loses free moisture to the refrigerator air. By morning it is dry enough to brown quickly while the interior stays hydrated.
The second technique is the two stage mushroom cook, and it exists because searing and braising want opposite conditions. High heat in a dry uncrowded pan builds the roasted notes that define a proper ragu di funghi, but the same heat held for twenty minutes would leave the mushrooms leathery. So the browning is fast and in batches, and the pieces then return to a low wet environment carrying everything the dried porcini gave up.
The third is using residual heat as a controlled cheese melter. Aged Taleggio is a washed rind cheese whose emulsion breaks around 150°F (65°C), above which the fat separates. A slab off the grill sits above that but cools fast and touches only one face, so thin slices soften and grip underneath while the tops stay intact.
Texture and Moisture Control
This plate is a controlled collision between a dry element and a wet one, and it holds for about four minutes. The polenta must arrive with a crust that gives way audibly under a fork and an interior still creamy, and that depends on the grill being genuinely hot before the polenta touches it. A moderate grill gives you hot polenta wearing stripes instead of grilled polenta.
The ragu has to be bound rather than merely wet. Judge it with the spoon track test, and if it is loose let it reduce longer rather than reaching for flour. If it has gone tight and dark, loosen it off the heat with a spoonful of reserved porcini liquid. The target is a ragu that stays where you put it, not one that floods the plate.
Moisture also has to be kept out of the crust from below. That is why the ragu goes on top of the cheese: the Taleggio forms a fat barrier between the wet ragu and the dry grilled surface. It is also why this dish is plated one order at a time and never held under a heat lamp, where trapped steam softens everything in three minutes.
Professional Mise en Place
The long part of this recipe happens the day before, which makes it more practical for service than it looks. Everything except the grilling, the cheese and the truffle is done in advance.

Chef Tips
Buy coarse stone ground bramata and accept the fifty minutes. Instant polenta is pre gelatinised and sets into a soft block with no structure, so the slabs slump on the grill and break when turned. The coarse grind also gives the interior the gritty bite that makes the crust worth having.
Salt the polenta water at the start and taste it before the meal goes in. It should taste like a well seasoned soup, because cornmeal absorbs seasoning as it hydrates and salt stirred in at the end never travels through the mass.
Judge a truffle by smell and weight before buying. A good black winter truffle is heavy for its size, firm under thumb pressure and smells of wet earth and cocoa. Store it wrapped in paper, not plastic, in a sealed jar in the refrigerator, and change the paper daily.
If fresh porcini are out of season, double the dried porcini to 1 oz (30 g) and make up the fresh weight with king oyster mushrooms in thick wedges. They brown well and hold their shape. Button mushrooms will not: they water out and bring nothing.
Common Mistakes
Grilling polenta that has not set long enough. Six hours refrigerated is a minimum and overnight is better. Polenta still soft in the middle bows under its own weight on the grate and tears when you turn it.
Moving the polenta too early on the grill. It releases itself when the crust has formed, usually after 4 to 5 minutes. Lifting a corner to check at two minutes tears the surface and guarantees sticking for the rest of the cook.
Melting the Taleggio under a broiler. Direct radiant heat pushes a washed rind cheese past the point where its emulsion holds and it splits into oil and curd. Let the residual heat of the polenta soften thin slices instead.
Shaving the truffle in the kitchen. Its aroma compounds are volatile and start leaving the moment the slices are cut, so a truffle shaved five minutes early reaches the table with a fraction of its perfume.
Wine Pairing
Valpolicella Ripasso DOC: A Veneto wine for a Veneto dish. Passed over the dried Amarone skins, it gains depth and a dried cherry sweetness that meets the browned mushrooms directly, while its acidity stays high enough to cut the Taleggio.
Gattinara DOCG: Nebbiolo from the volcanic soils of northern Piedmont, and the classical answer to black truffle. Tar and rose find the truffle instantly, while firm tannin and high acidity strip the butterfat of the cheese from the palate. Choose a bottle with six or seven years on it.
Alto Adige DOC Lagrein: Deep, dark and unmistakably Alpine, with violet and bitter chocolate over a tannin that is grainy rather than gripping. That texture echoes the coarse grind of the polenta instead of fighting it, and there is enough weight for the seared porcini.
Soave Superiore DOCG: The white that works here. Garganega from the volcanic hills east of Verona gives yellow apple, white pepper and a saline finish, with a waxy mid palate that carries Taleggio and a restrained acidity that lifts the ragu without clashing with the truffle.
Teroldego Rotaliano DOC: From the gravel plain of the Campo Rotaliano in Trentino, the most fruit forward option here. Dark berry fruit and bright acidity meet the smoke off the grill, and the tannin never argues with the mushrooms. Serve it around 60°F (16°C).
Storage & Reheating
The components keep separately and the assembled plate does not keep at all, so never build it ahead. Uncut set polenta keeps refrigerated on its tray, tightly covered, for up to 3 days. The ragu keeps in an airtight container for 3 days and improves on the second, once the dried porcini infusion has spread through the fresh mushrooms.
Reheat the ragu gently over low heat with a spoonful of water or reserved porcini liquid, and stop as soon as it steams. Grilled polenta is regrilled, not reheated: bring the slabs to room temperature, dry the surfaces again and give them 3 minutes a side on a hot grill pan. A microwave turns the crust to a damp skin in a minute.
Set polenta freezes well. Cut it into slabs, freeze them on a tray until solid, bag them for up to 2 months and grill from frozen with 2 extra minutes a side. The ragu freezes for 2 months, though the mushrooms soften. Do not freeze the Taleggio, which turns crumbly, or fresh truffle, which loses its aroma within days.
