Step-by-Step: How to Make Cheesy Baked Meatball Casserole

You don’t need to be a chef to pull this off. Just follow these steps, and you’ll be plating comfort in no time.

1. Mix Up the Meatballs

Start by combining the ground beef, breadcrumbs, parmesan, egg, garlic, onion, salt, and pepper in a large bowl. Don’t overmix—just enough to bring everything together.

Pro tip: Use your hands for this part. It helps blend the ingredients without toughening the meat.

Form the mixture into meatballs about 1 to 1.5 inches wide.

2. Brown (Optional, But Worth It)

If you’ve got a few extra minutes, sear the meatballs in a hot skillet with a bit of olive oil until browned on all sides. It locks in flavor and adds a satisfying texture. But don’t worry—if you skip this step, they’ll still cook perfectly in the oven.

3. Build Your Casserole

Grab a baking dish (9×13 works well). Spread a layer of marinara sauce on the bottom. Add the meatballs in a single layer. Pour the rest of the sauce over the top, then blanket the whole thing with shredded mozzarella.

You want every bite to be cheesy, so don’t skimp here.

4. Bake to Golden Perfection

Preheat your oven to 375°F (190°C). Bake uncovered for about 25 to 30 minutes, or until the cheese is bubbling and slightly golden and the meatballs are cooked through.

Let it rest for 5 minutes before serving. That’s when all the flavors settle and intensify.
