Ingredients

Instructions

  1. Step 1: Bring 4 cups water and 1 tsp salt to a boil in a medium saucepan. Slowly whisk in 1 cup coarse polenta to prevent lumps. Reduce heat to low and cook, stirring frequently, for 25 minutes until thick and creamy.
  2. Step 2: Remove from heat and stir in 1/2 cup grated Parmesan cheese and 2 tbsp butter until melted and smooth. Pour polenta into a greased 8x8-inch baking dish and spread evenly. Let cool and set for 15 minutes.
  3. Step 3: Preheat oven to 400°F. In a skillet, heat 2 tbsp olive oil over medium heat. Add 2 minced garlic cloves and sauté for 1 minute until fragrant. Add 1 1/2 cups canned crushed tomatoes, 1/4 cup chopped fresh basil, 1/2 tsp dried oregano, and 1/4 tsp black pepper. Simmer sauce for 10 minutes until slightly thickened.
  4. Step 4: Pour tomato-basil sauce evenly over the set polenta. Sprinkle 1/2 cup shredded mozzarella cheese on top.
  5. Step 5: Bake in preheated oven for 15-20 minutes until the cheese is bubbly and golden brown. Let cool for 5 minutes before slicing into squares and serving.
