Instructions

  1. Preheat your oven to 375 degrees F. Lightly grease a 9x9-inch (or similarly sized) baking dish with olive oil or nonstick spray.
  2. In a medium saucepan, heat olive oil over medium heat. Add chopped onion and garlic; sauté until softened and fragrant, about 3-4 minutes.
  3. Add the dried oregano, basil, thyme, salt, and pepper to the onions and garlic, stirring for 30 seconds to release the aromas.
  4. Slowly whisk in the vegetable broth, bringing the mixture to a gentle boil.
  5. Gradually whisk the polenta into the boiling broth mixture, reducing heat to low. Continue whisking frequently to prevent lumps and cook the polenta until thickened and creamy, about 10-15 minutes.
  6. Once the polenta is thick and creamy, remove from heat. Stir in half of the shredded mozzarella, all the ricotta cheese, and half of the Parmesan cheese until well combined.
  7. Stir in the fresh parsley, fresh basil, and red pepper flakes if using. Adjust seasoning with salt and pepper to taste.
  8. Pour the polenta mixture evenly into the prepared baking dish. Sprinkle the remaining mozzarella and Parmesan cheese evenly on top.
  9. Bake uncovered in the preheated oven for 25-30 minutes, until the top is golden brown and bubbly.
  10. Remove from the oven and let rest for 5 minutes before serving to set.
  11. Serve warm as a hearty, cheesy, herb-infused side dish or light main course that’s perfect for gluten-free family meals.
