If You Love Cheese, You Need These Meatballs
Okay, friend, let me paint you a picture: It's raining outside, the dog is tracking wet paw prints across the kitchen (again), and I'm standing over the stove trying not to burn dinner. Enter: these mozzarella stuffed meatballs. One bite and honestly? All the little annoyances of the day just melt away, kind of like the cheese inside these meatballs. I started making them for Sunday dinners when my cousin Jamie insisted we needed something "fancy but not, you know, fussy." Turns out, mozzarella stuffed meatballs are basically a hug in food form. Oh, and if you've ever tried to sneak a piece of cheese from the bowl and ended up with greasy hands — well, you're in good company here.
Why I Keep Making These Over and Over
I make these when I want to impress people without actually working that hard (lazy chef hack, right?). My family just goes wild for them — especially my brother, who claims he can "taste the love" (though honestly, I think it's just the cheese). There's something about the gooey mozzarella surprise in the middle that makes people think you spent hours, even if you didn't. The only frustration? Sometimes the cheese leaks out a bit in the oven. But you know what? That crispy edge is also incredible. I count it as a win-win.
Here's What You'll Need (and a Few Swaps)
- 500g ground beef (I've used ground turkey in a pinch; it's not the same, but it's good for a lighter version)
- ½ cup breadcrumbs (Panko makes them lighter. My grandmother always used the cheap stuff and swore that's why hers were the best — honestly, any kind seems to work)
- ¼ cup milk (I've used oat milk, and it was fine, maybe a bit sweeter)
- 1 large egg
- 2 cloves garlic, minced (or a big squeeze of that jarred stuff if you must — no judgment)
- ⅓ cup Parmesan cheese, grated
- 2 tablespoons fresh parsley, chopped (sometimes I skip it when I forget to buy it, no biggie)
- Salt & pepper (I don't even measure, just a good pinch of each)
- 160g mozzarella cheese, cut into 1cm cubes (I've tried string cheese in a rush — works surprisingly well!)
- 2 cups marinara sauce (store-bought, or try this one if you're feeling ambitious)
How I Throw These Together (With a Few Side Notes)
- Preheat your oven to 200°C (that's about 400°F, but honestly, if your oven runs hot just lower it a bit — mine's a bit moody).
- Grab a big bowl. In go the beef, breadcrumbs, milk, egg, garlic, parmesan, parsley, and your salt & pepper. Mix it all up with your hands (use gloves if you want, but I just give my hands a good scrub after). Try not to overwork it — unless you like tough meatballs, which... do you?
- Take a walnut-sized chunk of the mixture, flatten it in your palm, and pop a cube of mozzarella in the center. Now, this is the fun (messy) part: wrap the meat around the cheese, pinching it closed so the mozzarella is completely covered. If a bit peaks out, just squish it back in. Repeat until you run out of meat mixture or patience.
- Arrange your meatballs in a single layer in a baking dish. Honestly, don't worry if they smush together a bit. Pour the marinara sauce over the top. If you want, save a bit of cheese to sprinkle on top. Or not. Up to you.
- Bake for about 25 minutes, or until the meatballs are browned and the sauce is bubbling away. Sometimes I give them a little shake halfway through so they don't get stuck, but sometimes I forget and it's... fine.
- Let them cool a few minutes before serving. This is where I usually burn my tongue because I can't wait. (Don't be me.)
Some Notes From My Many Mess Ups
- If your cheese leaks out, don't stress. The crispy bits around the edge are actually my favorite part.
- I used to make these in a frying pan, but baking is less fuss and you get more even cheese melt. Actually, I find it works better if you don't crowd the pan too much.
- If you forget the parsley, nobody will notice except maybe you. I sometimes skip it.
Variations I've Tried (And One That Flopped)
- I swapped out mozzarella for smoked cheddar once — it was delicious, but really salty. Maybe use less salt if you try it.
- Turkey mince instead of beef is a good change, but you need to add a splash more milk or the meatballs get dry. I learned that the hard way.
- Once, on a dare, I tried stuffing them with blue cheese. Let's just say... don't. It's not great. Too strong for this dish — or maybe just for me!
- For a spicy kick, I've added a pinch of chili flakes to the meat. Not strictly traditional, but pretty tasty.
You Don't Need Fancy Gadgets (But They Help)
Look, a mixing bowl and your own two hands are the main tools here. A baking dish is key, but I've absolutely made these in a deep roasting tray when the proper pan was in the dishwasher. If you don't have a garlic press, just chop it fine — or, as mentioned, go for the pre-minced stuff. No shame.

How to Store (But Good Luck Having Leftovers)
Stick any leftovers (ha!) in an airtight container and pop 'em in the fridge. They'll be good for 2-3 days. They reheat pretty well in the microwave, but I actually think they taste better the next day — the flavors have a chance to cozy up. But, honestly, in my house these barely last the night.
Serving: How I Like to Plate 'Em
I love piling these on top of spaghetti, with extra sauce spooned on top and a snowstorm of parmesan. Sometimes we have them with a big pile of garlicky greens on the side just so I can pretend it's healthy. Oh, and a chunk of crusty bread to mop up the sauce is never a bad idea. My cousin dips hers in ranch — I don't get it, but to each their own.
Stuff I Learned the Hard Way (So You Don't Have To)
- Don't rush the rolling. If you do, the cheese will burst out everywhere and you'll be left with sad, hollow meatballs (learnt that one the messy way).
- I once tried using low-fat cheese to be "good"; it just dried out and went rubbery. Not worth it.
- Actually, I find it works better if you chill the meatballs for ten minutes before baking. Not essential, but the cheese stays inside better.
FAQ (Real Questions I've Had Thrown At Me)
- Do I have to use mozzarella? Nope! Any mild, melty cheese works. I've used Monterey Jack, and it was great. But mozzarella is classic for a reason.
- Can I freeze them? Yeah — freeze them before baking for best results. Just freeze on a tray, then chuck 'em in a bag. Bake straight from frozen, just add ten minutes or so.
- Is it okay if my sauce is super runny? Absolutely. It'll thicken a bit as it bakes. Or, if it's too thick, just thin it with a splash of water — not a big deal!
- What's the best marinara? Honestly, I just use Rao's or the Aldi knockoff. But if you're up for a homemade version, this one is legendary.
- Why did my cheese disappear? Sometimes the cheese just melts right out. Try making sure you really seal the meat around it. Or just embrace the crispy cheese edges, because they're really the best bit.
Anyway, if you give these mozz-stuffed meatballs a try, let me know how it goes. And if you find a better cheese to use, I'm all ears. Or stomach, in this case.
