Let’s make it
Preparation
Preheat the oven to 190°C (375°F). Lightly grease a 9x13 inch baking dish with olive oil.
Cooking Rice
In a medium saucepan, bring 3 cups of water to a boil. Add the rinsed rice, reduce heat to low, cover, and simmer for 15 minutes until water is absorbed and rice is tender. Remove from heat and let stand covered.
Sauté Vegetables
While the rice cooks, heat 2 tablespoons olive oil in a large skillet over medium heat. Add chopped onion and sauté until translucent, about 4 minutes.
Sauté Vegetables
Add minced garlic, diced red and green bell peppers to the skillet. Cook, stirring often, until peppers begin to soften, about 5 minutes.
Prepare Vegetable Mixture
Add chopped tomatoes and broccoli florets to the skillet. Stir in dried oregano, dried basil, salt, and black pepper. Cook for 5 more minutes until vegetables are tender but still crisp.
Assemble Casserole
Combine the cooked rice and sautéed vegetable mixture in a large bowl. Mix well to evenly distribute vegetables and seasonings.
Assemble Casserole
Transfer the rice and vegetable mixture to the prepared baking dish. Spread evenly. Sprinkle grated cheddar cheese and parmesan cheese evenly over the top.
Baking
Bake uncovered in the preheated oven for 25–30 minutes or until the cheese is melted and bubbly with a light golden crust.
Finishing
Remove from oven and let the casserole rest for 5 minutes before serving to allow flavors to meld and casserole to set slightly.
Tips & notes
Rinse the rice well before cooking to remove excess starch for fluffier results. You can substitute the cheddar with a sharp mozzarella for a milder cheese flavor. If preferred, add red pepper flakes for a hint of heat. Leftover casserole can be reheated and tastes even better the next day.
Saving it for later
Store any leftover casserole in an airtight container in the refrigerator within two hours of serving. It will keep well for up to 3 to 4 days.
Reheating
Reheat leftovers covered in a microwave-safe dish on medium power for 2–3 minutes or until heated through, stirring halfway. Alternatively, reheat in a 175°C (350°F) oven covered with foil for about 15 minutes until warmed evenly.
