Ingredients

  • 8 cups (2 L) water
  • 1 tablespoon sea salt
  • 2 cups (325 g) medium-coarse polenta
  • 4 tablespoons olive oil
  • 1 medium onion, peeled, halved, and sliced (about 1 1/2 cup)
  • 3 (14-ounce or 400-g) cans diced tomatoes (42 ounces or 1,200 g)
  • 2 cloves garlic, peeled and halved
  • 1/2 ounce (15 g) dried mushrooms, soaked in hot water and finely chopped (about 1/4 cup)
  • 1/2 bunch chopped fresh basil leaves (about 1/2 cup)
  • Sea salt and freshly ground black pepper
  • Freshly grated Parmigiano or Romano cheese

Method

  • Bring water and salt to a boil in a large pot over high heat.
  • Slowly add polenta in a steady stream, stirring continuously with a long wooden spoon.
  • Lower heat to a gentle boil and continue stirring 30 minutes or until polenta pulls away from the sides and is not gritty.
  • You may need to use more water as it cooks.
  • Use boiling water.
  • Cover pot with buttered waxed paper and place in a warm-water bath.
  • Polenta stays hot up to 3 hours.
  • Make sauce: Heat oil in a large skillet over medium-high heat; add onion and cook, stirring occasionally, 10 minutes or until onion begins to carmelize; stir in tomatoes, garlic, and mushrooms, reduce heat to medium-low, and cook, uncovered, 15 minutes; stir in basil, salt, and pepper.
  • Pour hot polenta onto a clean, unfinished wooden table or a large chopping board, 18 x 18 inches (45 cm x 45 cm), and shape into a thick circle.
  • Make a 4-inch (10-cm) indent in the center, pour in tomato sauce, and sprinkle with cheese.
  • Variations:
  • Let cool and then slice into pieces for frying.
  • Mix in diced mozzarella or fontina cheese.
  • Use half water and half milk to make dish more flavorful.
  • Cut into slices, put overlapping in buttered baking pan, drizzle with olive oil, and top with lots of grated Parmiggiano cheese.
  • Bake at 400F (200C) until browned.
