I threw these together last winter when we were all sick of holiday leftovers but not quite ready for January salads. The idea came from a restaurant dish my husband couldn't stop talking about, though he balked at the $24 price tag for five meatballs. After some experimenting in my kitchen, these cheese stuffed beauties have become our go to when we need comfort food that feels a little special.

My brother in law, who considers himself something of a food snob after watching too many cooking shows, actually asked for seconds last month when I made these. Later his wife texted asking for the recipe because he'd mentioned them three times that week. When someone who regularly critiques restaurant meals wants your recipe, you know you've nailed it.

Ingredients

Ground beef needs some fat in it - the super lean stuff might seem healthier but leaves you with dry, hockey puck meatballs. The 80/20 blend is perfect here.

Fresh mozzarella makes all the difference. I tried using the pre shredded bag stuff once when I was in a hurry, and while it worked technically, it didn't have that dramatic cheese pull that makes these special.

Panko breadcrumbs create a lighter texture than regular breadcrumbs. Those Japanese style crumbs somehow make everything less dense without falling apart.

Fresh parsley isn't just a garnish - it adds this brightness that cuts through all the richness. I've used dried in a pinch, but fresh really does taste noticeably better.

Marinara sauce doesn't need to be homemade to be good. I keep Rao's in my pantry for nights when I want something that tastes like it simmered all day without actually having to simmer anything all day.

Step-by-Step Instructions

Mixing the meat by hand
feels gross but works better than using a spoon. I've learned to take off my rings and just accept the cold, squishy reality of meatball making. Something about hand mixing distributes everything more evenly without overworking the meat.
Cutting the cheese into the right sized cubes
took some trial and error. My first attempt used pieces that were way too big, and they burst through the meat like something from an Alien movie. Now I aim for pieces about the size of a dice.
Sealing the meat around the cheese completely
is non negotiable, unless you enjoy cleaning burnt cheese off the bottom of your pan. I've found that flattening the meat in my palm, adding the cheese, then gradually folding and rolling creates the best seal.
Browning them properly before adding sauce
makes a huge difference in flavor. That caramelization on the outside creates depth that you just can't get otherwise. I've tried skipping this when in a hurry, and it's never as good.
Flipping them gently
is key unless you want a pan full of broken meatball pieces. I use a silicone spatula and move them one by one rather than trying to shake the pan like I'm some sort of TV chef.
Simmering
is where the magic happens - not just for cooking them through, but for letting all those flavors meld together. The sauce gets into the meat, the meat flavors the sauce, and everything just works better together.

My biggest kitchen fail with this recipe happened when I tried to multitask during the browning stage. I walked away to help my son with homework, got distracted, and came back to carbonized meat spheres that no amount of sauce could save. These aren't difficult, but they do require your attention for that critical cooking stage.

Serving Ideas

Pasta is the obvious choice here, and thick spaghetti or bucatini holds up nicely to these substantial meatballs. That sauce grabbing ability is key.

Garlic bread on the side isn't just traditional, it's essential for sopping up every last bit of that sauce. I usually cheat with store bought, but add my own butter mixed with fresh garlic and a sprinkle of dried parsley.

A simple green salad with nothing more than olive oil, lemon, and salt balances all that richness perfectly. Sometimes simple is best when the main dish has so much going on.

Changing It Up

Using half beef and half Italian sausage creates this incredible flavor depth that makes them taste even more special. Remove the sausage from its casing and mix it right in with the beef.

Adding a pinch of red pepper flakes to the meat mixture gives a subtle heat that builds as you eat. Not enough to overwhelm, just enough to keep things interesting.

Swapping the parmesan for pecorino romano adds a sharper, saltier element that plays really well with the mild mozzarella. It's a small change that makes a noticeable difference.

Serving them as sliders instead of over pasta turns these into perfect party food. Just add a small meatball to a dinner roll with extra sauce and watch them disappear at your next gathering.

I've made these for new parents, for dinner parties, and for random Tuesdays when we need something reliable that everyone will eat without complaints.

Frequently Asked Questions

→ Can I use pre-shredded mozzarella instead of fresh?
Fresh mozzarella creates the best melty, gooey center, but in a pinch, you can use low-moisture mozzarella cut into cubes. Pre-shredded mozzarella contains anti-caking agents that affect how well it melts.
→ Can I bake these meatballs instead of cooking on the stovetop?
Yes! Bake them at 400°F for about 15-20 minutes, then transfer to a pot with warm marinara sauce and simmer for 5-10 minutes.
→ How do I prevent the cheese from leaking out?
Make sure the mozzarella is completely sealed inside the meat mixture, with no thin spots. Using cold mozzarella straight from the refrigerator also helps prevent leakage.
→ Can I use different types of ground meat?
Absolutely! A mixture of ground beef and pork works wonderfully, or you can use ground turkey or chicken for a lighter option (though they may be slightly less juicy).
→ Can I make these ahead of time?
You can prepare the meatballs up to the browning stage, then refrigerate for up to 24 hours. When ready to serve, simmer in sauce until heated through. They also freeze well both raw and fully cooked.

Ingredients

→ For the Meatballs

01 1 pound ground beef
02 1 large egg
03 1 small onion, finely diced
04 4 garlic cloves, minced
05 ¼ cup fresh parsley, finely chopped
06 ½ cup Panko breadcrumbs
07 ¼ cup Parmesan cheese, grated
08 ½ teaspoon dried basil
09 ½ teaspoon dried oregano
10 ½ teaspoon salt
11 Freshly ground black pepper, to taste
12 4 ounces fresh mozzarella cheese

→ For Cooking and Serving

13 1-2 tablespoons olive oil
14 2 cups marinara sauce
15 Fresh parsley, chopped (for garnish)
16 Grated Parmesan cheese (for serving)

Instructions

Step 01

In a large mixing bowl, combine the ground beef, egg, finely diced onion, minced garlic, chopped parsley, Panko breadcrumbs, Parmesan cheese, dried basil, dried oregano, salt, and pepper. Mix thoroughly using your hands until all ingredients are evenly incorporated.

Step 02

Cut the fresh mozzarella cheese into approximately ½-inch cubes. You'll need 12 pieces total, one for each meatball.

Step 03

Scoop about 2 tablespoons of the meat mixture into your palm. Flatten it slightly, creating a small indentation in the center. Place a mozzarella cube in the middle, then carefully fold the meat around the cheese, sealing it completely. Roll between your palms to form a ball. Repeat with remaining mixture to make 12 meatballs.

Step 04

Heat the olive oil in a large non-stick skillet over medium-high heat. Once hot, add the meatballs, being careful not to overcrowd the pan (work in batches if necessary). Brown the meatballs on one side for 2-3 minutes, then carefully flip and brown the other side for another 2-3 minutes.

Step 05

Once all meatballs are browned on both sides, pour the marinara sauce into the pan, making sure all meatballs are covered. Reduce heat to medium-low, cover the pan, and let simmer for about 10 minutes. Gently turn the meatballs halfway through cooking to ensure they cook evenly.

Step 06

After simmering, cut one meatball in half to ensure it's cooked through. The center should reach 160°F on a meat thermometer and no longer be pink. The mozzarella inside should be completely melted.

Step 07

Serve the meatballs and sauce over cooked pasta of your choice. Garnish with freshly chopped parsley and additional grated Parmesan cheese.

Notes

  1. For extra flavor, add a pinch of red pepper flakes to the meat mixture or the marinara sauce.
  2. These meatballs are also delicious served on toasted sub rolls for meatball sandwiches.
  3. Leftover meatballs freeze well and can be reheated in sauce for a quick meal.
  4. Make sure to completely seal the mozzarella inside the meat to prevent cheese from leaking during cooking.
