This is one of those recipes that works especially well when you have leftover rice in the refrigerator. Instead of reheating it as a simple side dish, you can transform it into a complete family meal using familiar ingredients.
In addition to being easy, the recipe can be customized with different vegetables, cheeses, and proteins. Serve it on its own or accompany it with a fresh salad, roasted vegetables, or a light homemade juice.

Why Make Cheesy Baked Rice with Ham?
This recipe is perfect when you want to use cooked rice in a different and more flavorful way. The rice absorbs the creamy sauce, while the ham and vegetables add color, texture, and savory flavor.
Another advantage is that everything is assembled in a single baking dish. Once the ingredients are mixed, the oven handles most of the remaining work.
Mozzarella creates a soft and stretchy topping, while cheddar provides a stronger flavor. You can use either cheese or combine them with Parmesan for a more golden surface.
The casserole can also be prepared several hours in advance. Keep it covered in the refrigerator and place it in the oven shortly before lunch or dinner.

How to Make Cheesy Baked Rice with Ham
Begin by preheating the oven to 375°F, or approximately 190°C. Lightly grease a medium or large baking dish with butter, oil, or cooking spray.
If the cooked rice has been refrigerated, separate any firm clumps with a fork before adding it to the casserole.
Heat the olive oil in a small skillet over medium heat. Add the chopped onion and cook for approximately three to four minutes.
Stir occasionally until the onion becomes soft and translucent. Add the chopped garlic and cook for another 30 seconds.
Remove the skillet from the heat and set the onion and garlic aside while you prepare the creamy mixture.
Place the milk, sour cream, eggs, dried parsley, garlic powder, salt, and black pepper in a medium bowl.
Whisk until the eggs are completely blended and the sour cream is evenly incorporated into the liquid.
Place the cooked rice in a large bowl. Add the diced ham, peas and carrots, corn, cooked onion, and garlic.
Add one cup of mozzarella and the shredded cheddar. Reserve the remaining mozzarella and all the Parmesan for the topping.
Pour the milk and egg mixture over the rice. Stir gently until all the ingredients are evenly distributed and lightly coated.
Transfer the rice mixture to the prepared baking dish. Use a spoon or spatula to spread it into an even layer.
Avoid pressing the rice too firmly. Keeping the mixture slightly loose allows the sauce to move between the grains during baking.
Sprinkle the remaining mozzarella over the surface. Finish with the grated Parmesan.
Cover the baking dish loosely with aluminum foil. Place it in the preheated oven and bake for approximately 20 minutes.
Carefully remove the foil and continue baking for another 15 to 20 minutes.
The casserole is ready when the center is hot, the cheese is melted, and the surface is lightly golden.
For additional color, place the dish under the broiler for one or two minutes. Watch it carefully because the cheese can darken quickly.
Remove the baked rice from the oven and allow it to rest for approximately five minutes.
This short resting time helps the creamy mixture settle and makes the casserole easier to divide into portions.
Finish with chopped parsley or green onions and serve while the cheese is still warm.

Tips for Making the Perfect Baked Rice
Use fully cooked rice for this recipe. Raw rice will not have enough liquid or cooking time to become tender inside the casserole.
Cold leftover rice works especially well because the grains are firmer and easier to combine with the other ingredients.
Separate large clumps before mixing. This helps distribute the ham, vegetables, cheese, and sauce more evenly.
Taste the ham before adding too much salt. Some varieties are naturally salty, and Parmesan also contributes additional seasoning.
Drain canned corn thoroughly. Excess liquid can make the casserole watery.
Thaw frozen vegetables before adding them. Very cold or icy vegetables may release excess moisture and increase the baking time.
Do not use an excessively deep or small dish. A medium casserole dish allows the center to heat evenly while the top becomes golden.
Cover the casserole during the first part of baking. This prevents the cheese from browning before the interior becomes completely hot.
Use freshly shredded cheese whenever possible. It generally melts more smoothly than pre-shredded varieties.
For a crisp topping, combine half a cup of breadcrumbs with one tablespoon of melted butter and sprinkle the mixture over the cheese.
Cooked chicken, turkey, bacon, or sausage can replace the ham. Make sure any meat added to the casserole is already fully cooked.
Broccoli, bell peppers, mushrooms, zucchini, spinach, or green beans can be added or substituted for the peas, carrots, and corn.
Cook vegetables that contain a large amount of moisture before adding them. This is especially important for mushrooms, zucchini, and spinach.
For a richer casserole, replace part of the milk with heavy cream. For a lighter version, use plain yogurt instead of sour cream.
The dish can be assembled several hours in advance. Cover it tightly and refrigerate until needed.
When baking a refrigerated casserole, add approximately ten minutes to the covered cooking time.
Store leftovers in a covered container in the refrigerator for up to three days. Reheat individual portions in the microwave or warm the entire dish in a low oven.
