These Slow Cooker Italian Meatballs are one of my favorite go-to recipes for basically anything. They taste great on their own as an appetizer, but also work well with pasta or on sub sandwiches with melty cheese. They’re freezer-friendly, too — meaning you can make a double-batch now and save some for later.
I realllllly wanted to title this post “slow cooker Italian meat-a-balls” because that’s how I always say it in my head. But we’re trying to keep it profesh around here, so the traditional spelling wins out (though you’ll totally say “meat-a-balls” in your head now, too. You’re welcome).
This is one of the recipes I made pre-baby for our freezer stash, and I made a royal mistake with them — I froze all eleventy billion (or, like, 40) of them in one container. Do you know where I’m going with this? It means I had to thaw all 40 meatballs for me, my husband and my mom (who was staying with us at the time) at once. I was shaking in my boots that some of these delicious meat-a-balls would end up going to waste.
How to Make Slow Cooker Italian Meatballs
Well it turns out I completely underestimated my husband’s love for the meatball, because they were all gone — GONE — in two days. Down the hatch in meatball sub form, on top of pasta, cold and sliced and placed atop whole-grain toast (YUM, really), etc. OK, OK — my mom and I helped, too.
Needless to say, this recipe is one of those low-effort, high-result recipes that you’re going to want to make again and again (just maybe freeze them in batches if you do, unless you love eating meatballs for two days straight like my husband).

The slow cooker is my friend in so many ways, and if you have one, you probably agree. It’s so helpful for those hustle-bustle days when dinner is the last thing you want to/have time to make. It also comes in handy when it’s 100 degrees outside and you want to avoid that oven at all costs (except maybe to bake chocolate chip cookies. No amount of heat will keep me from my cookies). And I love using it to make big ol’ batches of easy-peasy foods like these here meatballs, which I intended to use for at least three to four separate meals over the course of, like, a month (see above how that did not go as planned, but all is well).

Making meatballs in the slow cooker is especially delicious because I feel like slow-cooked meat and tomatoes are some of the best things to exist in life. But with a slow cooker, you have to do very little prep work. So the end result is something that tastes like you slaved over it for hours and hours when in reality, you spent about 15 minutes making it happen. WINNER.
How to Serve Slow Cooker Italian Meatballs
Like I mentioned before, we enjoyed these meatballs as cheesy meatball subs, on top of spaghetti with classic Italian bread, cold for lunch on toasted, crusty, whole wheat sourdough bread and just by themselves with a big Italian salad on the side. Finish that easy Italian-themed dinner with panna cotta, one bowl olive oil cake, or moist blueberry ricotta cake.

Slow Cooker Italian Meatballs

Ingredients
- ½ cup milk
- 4 eggs
- 2 pounds ground beef
- 12 ounces mild Italian sausage, bulk, or casings removed
- 1 ¼ cups Italian seasoned breadcrumbs
- ¼ cup Parmesan cheese, shredded
- 2 teaspoons salt
- ½ teaspoon pepper
- ¼ teaspoon garlic powder
- 6 cups marinara pasta sauce , 2, 24 ounce jars or homemade marinara pasta sauce
Instructions
- In a large bowl, whisk together milk and eggs until combined. Add ground beef, Italian sausage, breadcrumbs, Parmesan cheese, salt, pepper and garlic powder; stir with a wooden spoon or mix with your fingers until well combined.
- Heat broiler to high; place an oven rack about 4 to 5 inches from the broiler. Lightly grease 2 baking sheets with cooking spray or oil. Using your hands, shape (about 40) 1 to 2-inch meatballs from the mixture; place on prepared baking sheets.
- Broil meatballs 6 to 8 minutes, flipping halfway through, until browned. Transfer to a 6-quart slow cooker.
- Top meatballs evenly with sauce. Cover and cook on low 4 to 5 hours in the slow cooker until meatballs are cooked through to an internal temperature of at least 160 degrees F.
- Serve on top of pasta, on split hoagie rolls with melty cheese for meatball sub sandwiches, alongside buttery mashed potatoes or on their own as an appetizer.
- TO FREEZE: Let meatballs and sauce cool completely. Place in a resealable plastic bag and freeze in a single layer; or, freeze in a Tupperware container. Thaw in the refrigerator overnight, then heat the thawed mixture (meatballs and sauce) together until heated through.
Notes
- This recipe makes a lot of meatballs, so if you don’t plan to freeze any I’d suggest halving the recipe.

Kaitlyn — I let them cool completely after cooking and froze everything in one container (sauce and meatballs). You could probably freeze them ahead of time, though, too!
How did you freeze them? Was it after cooked or before? Thanks, great recipe. 🙂
I have a feeling the same thing would happen in my house! My husband flips for meatballs and I don’t make them very often, why??? I’ll have to make these and be a hero 🙂
I’m with you – I love my crockpot for busy days. Few minutes prep and I know dinner is practically done! These meatballs sound amazing – I’ve never made meatballs in my crockpot which I am cursing myself for now! haha 🙂
We make a lot of Italian meat-a-balls (totally going to say it that way from now on!!) around here but I don’t use my slow cooker nearly enough. cant wait to try this deliciousness!!
These would be devoured in my house. I have no willpower around meatballs. I mean, they’re just so cute and bite sized. It’s like the perfect little snack…until you eat 10 of them. Oops.
I love slow cookers recipes!! and I would totally devour these meatballs in a sandwich with cheese. . yummmmo!
Gorgeous! Somehow you managed to make meatballs look ultimately gourmet. Love it!
Elizabeth — Oh, you totally can. It’s life changing. 🙂
I don’t make as many slow cooker meals as I should, but definitely need to make these soon. I would love to serve these meatballs over a big plate of pasta!
