• 2 cups shredded mozzarella or Swiss cheese

• 2 tablespoons olive oil

• 1 teaspoon dried thyme

• Salt and black pepper, to taste

4. Bake the casserole – Transfer mixture to a greased 9×13-inch baking dish. Cover with foil and bake at 350°F (175°C) for 45–50 minutes, until rice is tender.

5. Add cheese – Remove foil, sprinkle cheese evenly on top, and bake uncovered for an additional 10 minutes until melted and bubbly.

6. Serve – Garnish with fresh parsley and serve hot.

Tips for Success

• Caramelize the onions – The deeper the golden color, the richer the flavor.
