Method
Preheat the oven to 205°C (400°F) with a rack positioned in the center, and line a rimmed baking sheet with parchment paper.
Peel the carrots, parsnips, butternut squash, and red onion using a vegetable peeler, then cut them on a cutting board with a chef's knife into uniform 2 cm pieces.
Place the cut carrots, parsnips, butternut squash, and red onion into a large mixing bowl, add 30 ml extra virgin olive oil, 5 g chopped rosemary, 3 g fresh thyme, 4 g kosher salt, and 1 g black pepper, and toss thoroughly until all pieces are evenly coated.
Spread the seasoned root vegetables in a single uncrowded layer across the lined rimmed baking sheet, transfer to the oven, and roast at 205°C (400°F) for 35 to 40 minutes, turning once halfway through, until edges are caramelized and centers are tender.
While the vegetables roast, heat 15 ml extra virgin olive oil in a small saucepan over medium-low heat, add the minced garlic, and sauté gently for 1 to 2 minutes until fragrant and translucent without browning.
Pour 400 g canned crushed tomatoes, 1 g dried oregano, and 2 g kosher salt into the small saucepan with the garlic, reduce heat to low, simmer uncovered for 15 minutes while stirring occasionally with a silicone spatula, then remove from heat and fold in 5 g torn fresh basil.
In a heavy-bottomed saucepan, combine 750 ml vegetable broth, 250 ml whole milk, and 3 g kosher salt, and bring the liquid to a rolling boil at 100°C (212°F) over medium-high heat.
Slowly pour 180 g coarse yellow cornmeal in a steady thin stream into the boiling liquid while whisking continuously with a whisk to prevent clumps from forming.
Turn the heat down to low, cover the saucepan partially with a lid, and simmer the polenta for 30 minutes, stirring vigorously every 5 minutes with a wooden spoon across the bottom of the pan to prevent sticking and scorching.
Remove the saucepan from heat, immediately add 30 g cubed cold unsalted butter, 40 g finely grated parmesan cheese, and 1 g black pepper, and stir vigorously with the wooden spoon until thoroughly melted and glossy.
Divide the warm polenta evenly among 4 shallow serving bowls using a serving spoon, indent the center of each portion slightly, ladle the warm marinara sauce over the center if using, and mound an equal portion of roasted root vegetables directly on top.
Garnish each assembled bowl with additional fresh thyme leaves and cracked black pepper if desired, and serve immediately while piping hot.
Chef's Notes
- Choose coarse-ground yellow cornmeal labeled bramata or coarse polenta. Coarse grains hydrate slowly and deliver the traditional creamy, toothsome texture that instant versions cannot match.
- For even roasting, cut all dense root vegetables to the same 2 cm dimension. Carrots and parsnips take slightly longer to cook than squash, so cutting squash pieces marginally larger balances doneness.
- The marinara topping is optional but recommended; its bright acidity from San Marzano tomatoes cuts cleanly through the rich dairy fats in the polenta and balances the sweet earthiness of the roasted roots.
- If keeping warm for service, place a round of parchment paper directly onto the polenta surface inside the saucepan to prevent a tough starch skin from forming.
Storage
Refrigerator: 4 days — Store the polenta, roasted root vegetables, and marinara sauce in separate airtight glass containers to maintain distinct textures and avoid sogginess.
Freezer: 2 months — Freeze the roasted root vegetables and marinara sauce in freezer-safe containers for up to 2 months. Freezing polenta is not recommended as it weeps liquid and turns grainy upon thawing.
Reheating: Reheat polenta gently on the stovetop over low heat with a splash of vegetable broth or whole milk, whisking frequently until silky. Reheat roasted root vegetables and marinara sauce in a preheated oven at 175°C (350°F) or on the stovetop until an internal temperature of 74°C (165°F) is reached as confirmed by an instant-read food thermometer. Cool perishable leftovers within 2 hours of cooking and refrigerate promptly.
Troubleshooting
Polenta turns out lumpy with hard starch clusters
Cause: The cornmeal was dumped into the boiling liquid too quickly or was not whisked vigorously during addition
Fix: Immediately blend the polenta with an immersion blender off the heat until smooth, then return to low heat to finish simmering
Prevention: Stream the cornmeal in a very fine, steady drizzle with one hand while whisking vigorously in circles with the other
Roasted root vegetables become soft and soggy without browning
Cause: The baking sheet was overcrowded, which traps evaporating steam rather than allowing dry heat roasting
Fix: Transfer the baking sheet to the top oven rack and broil at 230°C (450°F) for 3 to 4 minutes while watching carefully to prevent burning
Prevention: Arrange vegetables with at least 1 cm of space between pieces; divide onto two baking sheets if necessary
Polenta becomes stiff and paste-like before serving
Cause: Polenta cools rapidly and corn starches continue to set and retrograde once off the heat
Fix: Whisk in 60 to 120 ml of hot vegetable broth or hot milk over low heat until the creamy, pourable consistency is restored
Prevention: Keep polenta covered on the lowest burner setting until ready to plate, folding in butter and cheese at the final minute
Cultural Context
Originating in Northern Italy, polenta was historically cooked in large unlined copper cauldrons called paioli over open wood hearths to sustain rural communities through severe Alpine winters. Traditionally paired with wild forest mushrooms, braised roots, and cellar vegetables, it epitomizes the Italian philosophy of cucina povera, transforming humble pantry grains and farm-grown roots into a deeply restorative winter feast.
