Corn flour casseroles are enjoyed year round across northeast Argentina and Paraguay, but every spring and summer, when corn is sweet and abundant, this cheesy fresh-corn version  becomes a staple. Cook Gisela Wadiana Medina, co-founder of Cocineros del Iberá, a network of more than 100 cooks and food producers across the Argentine province of Corrientes, shares her version: a simple, six-ingredient chipá guazú that lets the sweetness of just-harvested corn shine through.

Yield: serves 8
Time: 1 hours 15 minutes


  • ½ cups corn oil, plus more for greasing
  • 2 large yellow onions, coarsely chopped (2 cups)
  • 12 large ears yellow sweet corn, shucked
  • 6 large eggs
  • 2 tsp. kosher salt
  • 1 lb. Tybo cheese (or Monterey Jack), cut into ½-in. cubes


  1. Position a rack in the center of the oven and preheat to 350ºF. Oil a 9- by 13-inch baking dish and set aside.
  2. To a large skillet set over medium heat, add the oil and onions and cook, stirring occasionally, until softened and browned in spots, about 15 minutes. Remove from the heat and set aside.
  3. Using a box grater set over a rimmed baking sheet, grate the kernels off the corncobs (discard the cobs). In a large bowl, beat the eggs with the salt, then stir in the corn (with its liquid), the reserved onions, and the cheese until you have a thick, chunky batter.
  4. Scrape the batter into the prepared baking dish, smooth the surface, and bake until the top is golden and a toothpick inserted into the center comes out with a few crumbs attached, about 35 minutes. Remove from the oven and cool for at least 20 minutes before cutting into 2-inch squares.
