About This Recipe

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.

Ingredients

Serves 4

  • 1 cupcoarse polenta cornmeal
  • 4 cupsvegetable or chicken stock
  • 1.5 tspsalt(divided)
  • 3 tbspbutter(divided)
  • 0.5 cupgrated parmesan
  • 3 tbspolive oil
  • 3onions(thinly sliced)
  • 1 tspsugar
  • 0.25 cupparsley(chopped)

Instructions

  1. 1

    Caramelize the onions

    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.

  2. 2

    Boil the stock

    In a separate heavy pot, bring stock and 1 teaspoon salt to a boil.

  3. 3

    Add the polenta

    Whisking constantly, slowly stream in the cornmeal to prevent lumps. Reduce heat to low.

  4. 4

    Simmer and stir

    Simmer, stirring every few minutes, for 30 to 35 minutes until thick and creamy, and the cornmeal has lost its raw, gritty edge.

  5. 5

    Finish the polenta

    Stir in 2 tablespoons butter, parmesan and remaining salt until smooth.

  6. 6

    Serve

    Spoon polenta into bowls, top generously with caramelized onions, a pat of remaining butter, and a scatter of parsley.

Pro Tips

  • →

    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.

Variations

  • •

    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.

Storage

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.

History & Origin

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.

Frequently Asked Questions

Can I use instant polenta to save time?

Yes, it cooks in about 5 minutes according to package instructions, though the texture is less creamy and satisfying than slow-cooked coarse polenta.

Why is my polenta lumpy?

The cornmeal was likely added too quickly or without constant whisking; stream it in slowly while whisking vigorously to prevent clumps from forming.

Can I make the caramelized onions ahead?

Yes, they keep well refrigerated for up to a week and reheat easily in a pan, making them a good make-ahead component.
