Polenta lasagna

Instructions

1. In a large saucepan, bring 6 cups of water to a boil. Add 1 teaspoon of salt and gradually whisk in polenta.
2. Reduce heat to low and cook, stirring frequently, until thickened, about 5 minutes. Stir in butter and remove from heat.
3. Spread the cooked polenta evenly onto a baking sheet to cool and firm up, forming a layer about 1/2 inch thick. Let it cool completely.
4. Preheat oven to 375°F (190°C).
5. In a skillet, heat olive oil over medium heat. Add onions and garlic, sauté until onions are translucent, about 5 minutes.
6. Add sausage to the skillet, breaking it apart with a spoon, and cook until browned. Stir in tomato passata, oregano, 1/2 teaspoon salt, and pepper.
7. Simmer the sauce for 10 minutes, then remove from heat.
8. Cut cooled polenta into squares or slices. Layer half the polenta slices in a greased 9x13 inch baking dish.
9. Spread half of the sausage-tomato sauce over the polenta, then sprinkle half of the mozzarella and Parmesan cheese.
10. Repeat the layers with remaining polenta, sauce, and cheeses. Bake in the oven for 25-30 minutes until the cheese is bubbly and golden.
11. Let the polenta lasagna cool for a few minutes before serving. Garnish with fresh basil leaves.
