Creamy stone-ground polenta topped with slowly caramelized onions and parmesan, a comforting northern Italian-Argentine dish.
Polenta arrived in Argentina alongside heavy Italian immigration in the late 19th and early 20th centuries and remains a common, affordable comfort food, especially in the country's colder southern regions. Cooked low and slow with frequent stirring, cornmeal transforms into a thick, creamy porridge that can be topped with anything from tomato sauce to grilled meats, though a simple topping of deeply caramelized onions and grated cheese is one of the most beloved everyday versions. The defining technique of good polenta is patience with the stirring — cornmeal added to boiling liquid needs to be whisked constantly at first to prevent lumps, then stirred regularly throughout a 30 to 40 minute simmer so it doesn't stick and scorch on the bottom of the pot. Using stock instead of water and finishing with butter and cheese are what separate a restaurant-quality bowl from a bland one. The caramelized onions need their own patience — a full 30 minutes over low heat, stirring occasionally, until they turn deep golden brown and jammy-sweet, which is what makes this simple topping taste far richer than the short ingredient list suggests.
Serves 4
Heat olive oil in a wide skillet over low heat. Add onions and sugar, and cook slowly, stirring occasionally, for 30 minutes until deep golden brown and jammy.
In a separate heavy pot, bring stock and 1 teaspoon salt to a boil.
Whisking constantly, slowly stream in the cornmeal to prevent lumps. Reduce heat to low.
Simmer, stirring every few minutes, for 30 to 35 minutes until thick and creamy, and the cornmeal has lost its raw, gritty edge.
Stir in 2 tablespoons butter, parmesan and remaining salt until smooth.
Spoon polenta into bowls, top generously with caramelized onions, a pat of remaining butter, and a scatter of parsley.
Whisk constantly when the cornmeal first hits the boiling stock — this is the single moment where lumps form if you rush it.
Cook the onions low and slow for the full 30 minutes; rushing them with high heat browns the outside while leaving the inside undercooked and sharp-tasting.
Use coarse, stone-ground polenta rather than instant cornmeal for a much better texture, even though it takes longer to cook.
Top with grilled Italian sausage instead of, or alongside, the caramelized onions for a heartier main.
Stir in extra parmesan and a splash of cream for an even richer, restaurant-style polenta.
Chill leftover polenta in a pan, then slice and pan-fry it crisp for a second-day version.
Refrigerate up to 4 days; polenta firms up significantly when cold. Reheat with a splash of stock or water, stirring over low heat to loosen back to a creamy texture.
Polenta became deeply embedded in Argentine cuisine through the massive wave of Italian immigration between 1880 and 1950, particularly among northern Italian immigrants for whom cornmeal was already a dietary staple.
Yes, it cooks in about 5 minutes according to package instructions, though the texture is less creamy and satisfying than slow-cooked coarse polenta.
The cornmeal was likely added too quickly or without constant whisking; stream it in slowly while whisking vigorously to prevent clumps from forming.
Yes, they keep well refrigerated for up to a week and reheat easily in a pan, making them a good make-ahead component.
