4. Combine Rice and Vegetables

In a large mixing bowl, combine the cooked rice, steamed vegetables, and cheese sauce. Mix gently until the rice and vegetables are evenly coated with the creamy sauce. The key here is to handle the mixture gently so the vegetables retain their shape and texture.

5. Assemble the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray. Pour the rice and vegetable mixture into the dish, spreading it evenly. Sprinkle the remaining ½ cup of shredded cheese on top to create a golden, bubbly crust during baking.

6. Bake to Perfection

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese on top is melted and slightly golden. For an extra-crispy top, you can broil for 1-2 minutes at the very end — just keep a close eye on it to prevent burning.

7. Serve Warm

Remove the casserole from the oven and let it sit for 5 minutes before serving. This helps the dish set slightly and makes it easier to serve. Pair it with a simple side salad or roasted protein for a complete meal.

Tips for the Perfect Vegetable Rice Casserole

Use leftover rice: Day-old rice works wonderfully because it absorbs the cheese sauce better without becoming mushy.
Mix cheeses: Combining sharp cheddar with mozzarella gives both flavor and a gooey, melty texture.
Add herbs: Fresh parsley or thyme can elevate the flavors.
Make it ahead: You can prepare the casserole a day in advance, refrigerate, and bake when ready — perfect for busy nights or potlucks.
