What Kind of Meatballs Work Best in This Easy Cheesy Meatball & Rice Dinner Casserole?

I’ve tested this casserole with both homemade and frozen meatballs, and the good news is: both work beautifully. For busy nights, I grab a bag of fully cooked frozen mini meatballs. They go straight from freezer to oven and still end up tender thanks to the steamy rice underneath.

If you have a batch of homemade meatballs in the fridge, use them! Just make sure they’re cooked through before adding them to the casserole. I like smaller, bite-size meatballs here so every scoop of rice gets a good mix of meat, cheese, and sauce.

Ingredients for the Easy Cheesy Meatball & Rice Dinner Casserole

Long-grain white rice
The rice is the cozy base of this casserole. Long-grain white rice cooks up fluffy and separate, soaking up all the tomatoey, seasoned broth so every bite is full of flavor.

Low-sodium chicken broth
Broth adds depth and savoriness as the rice cooks. Using low-sodium gives you more control over the final seasoning and keeps the casserole from tasting too salty once the cheese goes on.

Marinara sauce
Instead of plain tomato sauce, I use a garlicky marinara. It brings herbs, sweetness, and acidity that turn the rice into something that tastes like it came from your favorite Italian-American restaurant.

Diced tomatoes
A can of diced tomatoes adds juicy pops of texture and a little extra acidity. They help keep the rice moist and create that saucy layer you can scoop onto your plate.

Yellow onion
Finely diced onion melts into the rice as it bakes, adding sweetness and a savory backbone. You barely see it in the finished dish, but you’d miss it if it weren’t there.

Red bell pepper
Tiny cubes of red pepper bring color and a mild sweetness that balances the richness from the cheese and meatballs.

Italian seasoning
This blend of herbs (usually oregano, basil, thyme, and rosemary) makes the casserole taste like it simmered all afternoon. It seasons the rice and ties the meatballs and sauce together.

Garlic powder & onion powder
These pantry staples reinforce the fresh onion and the garlic in the marinara without any extra chopping. They’re my shortcut to big flavor in one-pan bakes like this.

Smoked paprika
Just a pinch adds warmth and a subtle smokiness that keeps the casserole from tasting flat. It also deepens the color of the sauce.

Kosher salt & black pepper
Simple, essential seasoning that wakes everything up. I season the rice mixture before baking so the flavors soak in as it cooks.

Frozen fully cooked mini meatballs
The star of the show. They sit on top of the rice and baste in the steam as the casserole bakes. Because they’re already cooked, you’re just heating them through and letting them absorb all that tomato-garlic goodness.

Mozzarella cheese
Mozzarella is what gives you those gorgeous cheesy pulls. It melts into stretchy strands that cling to every grain of rice and meatball.

Sharp cheddar cheese
Cheddar brings a deeper, tangier cheese flavor and helps the top brown beautifully. The combo of mozzarella and cheddar is what makes the casserole taste so comforting.

Parmesan cheese
A sprinkle of Parmesan over the top adds a salty, nutty finish and creates little golden-brown spots as it bakes.

Olive oil
A bit of olive oil keeps the rice from sticking to the dish and adds richness. I also drizzle some on top before the final bake for extra flavor and a glossy finish.

Fresh parsley
A shower of chopped parsley at the end brightens everything up and adds a fresh, herbal note that cuts through the richness.

How To Make the Easy Cheesy Meatball & Rice Dinner Casserole

Step 1: Prep the Baking Dish and Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a little olive oil so the rice doesn’t stick and the edges crisp up instead of burning.

Step 2: Build the Saucy Rice Base

Add the uncooked long-grain white rice straight into the prepared baking dish. Pour in the low-sodium chicken broth and marinara sauce, then stir in the diced tomatoes, finely diced onion, red bell pepper, Italian seasoning, garlic powder, onion powder, smoked paprika, kosher salt, and black pepper.

Use a spoon to mix everything until the rice is evenly distributed and submerged in liquid. This step is important—any rice peeking out may cook unevenly or dry out.

Step 3: Bake the Rice Until Mostly Tender

Cover the baking dish tightly with aluminum foil, crimping the edges well so steam can’t escape. Slide it into the oven and bake for about 40 minutes.

When you pull it out, carefully remove the foil (watch the steam!) and give the rice a stir. It should be mostly tender with just a little bite left and the mixture will look thick and saucy.

Step 4: Add the Meatballs and First Layer of Cheese

Nestle the frozen fully cooked mini meatballs evenly across the top of the rice, pressing them down slightly so they sit in the sauce without disappearing.

Sprinkle half of the shredded mozzarella and half of the shredded cheddar over the rice and meatballs. This first layer melts down into the casserole and makes it extra creamy.

Cover the dish with foil again and return it to the oven for another 20 minutes, just until the meatballs are heated through and the rice is fully tender.

Step 5: Finish With a Golden, Cheesy Top

Remove the foil and sprinkle the remaining mozzarella and cheddar over the top, followed by the grated Parmesan. Drizzle a bit more olive oil across the surface.

Bake the casserole uncovered for about 10 minutes, or until the cheese is melted, bubbling, and lightly golden in spots. If you like a deeper color, you can broil it for 1–2 minutes at the end—just keep a close eye on it.

Step 6: Rest, Garnish, and Serve

Take the casserole out of the oven and let it rest for 10 minutes so the rice can set and the slices hold together. Sprinkle generously with chopped fresh parsley.

Scoop big spoonfuls into shallow bowls or plates, making sure each portion gets plenty of cheesy rice and meatballs. Serve hot.

How to Serve and Store Easy Cheesy Meatball & Rice Dinner Casserole

When this casserole comes out of the oven, I like to bring the whole baking dish straight to the table and let everyone dig in family-style. A crisp green salad or a simple veggie side is all you need to round out the meal.

Leftovers are a gift. Once the casserole has cooled to room temperature, cover the dish tightly or transfer portions to airtight containers. It will keep in the fridge for up to 4 days.

To reheat, add a splash of broth or water to keep the rice from drying out, then warm individual portions in the microwave or reheat the whole pan in a 325°F (165°C) oven until heated through.

You can also freeze this casserole. Cool completely, wrap well, and freeze up to 2 months. Thaw overnight in the fridge and reheat, covered, until hot and bubbly.

What to Serve With Easy Cheesy Meatball & Rice Dinner Casserole?

Garlic Bread or Breadsticks

A warm, buttery slice of garlic bread (or pillowy breadsticks) is perfect for scooping up all the cheesy, tomatoey rice left on your plate.

Simple Green Salad

I love pairing this rich casserole with something crisp and fresh—think romaine or mixed greens tossed with a lemony vinaigrette. The acidity cuts through the richness of the cheese and meatballs.

Roasted Parmesan Green Beans

Roasted green beans with a sprinkle of Parmesan echo the cheesy flavors in the casserole but add a lighter, snappier texture on the side.

Steamed or Roasted Broccoli

Broccoli soaks up the extra sauce from your plate and adds a bit of green to an otherwise hearty, orange-and-gold casserole situation.

Caprese-Style Tomato Salad

Fresh mozzarella, tomatoes, basil, and a drizzle of balsamic glaze make a bright, juicy contrast to the baked cheese and rice.

Sautéed Zucchini or Squash

Quickly sautéed zucchini or yellow squash with garlic and olive oil is a simple side that keeps the focus on the casserole while still rounding out the plate.

Caesar Salad

If you want something a little more substantial than a basic green salad, a classic Caesar with crunchy croutons and plenty of Parmesan is always a hit with this dish.
