Slow Cooker Italian Meatballs – Tender, Saucy, and Comforting
Slow Cooker Italian Meatballs simmer into something special: tender bites tucked into a rich tomato sauce with barely any effort. You mix, roll, brown, then let the slow cooker do the rest. The meatballs turn out soft and juicy, and the sauce gets deep, savory flavor as it cooks low and slow.
Serve them over spaghetti, pile them into hoagie rolls, or spoon them onto creamy polenta. This is the kind of weeknight meal that tastes like you spent all day in the kitchen, without actually doing that.
Slow Cooker Italian Meatballs - Tender, Saucy, and Comforting
Ingredients
Method
- Make the panade: In a large bowl, combine the breadcrumbs and milk. Let sit for 2 to 3 minutes until the crumbs absorb the milk.
- Build the meatball mixture: Add the ground beef, ground pork, eggs, Parmesan, onion, garlic, parsley, basil, salt, pepper, oregano, and red pepper flakes to the bowl. Mix gently with your hands until just combined.Don’t overmix.
- Form the meatballs: Scoop and roll into golf ball–sized balls (about 1 1/2 inches). You should get 24 to 30 meatballs.
- Brown the meatballs: Heat olive oil in a large skillet over medium-high. Brown meatballs in batches, 1 to 2 minutes per side, just until they get a little color.Transfer to the slow cooker. Don’t worry if they’re not cooked through.
- Make the sauce: In the same skillet, add crushed tomatoes, tomato paste, a pinch of salt, a pinch of sugar, and bay leaves. Stir and scrape up browned bits.If thick, add water or broth to loosen. Pour sauce over the meatballs in the slow cooker.
- Slow cook: Cover and cook on Low for 5 to 6 hours or High for 3 to 4 hours, until meatballs are cooked through and very tender.
- Finish and serve: Remove bay leaves. Taste and adjust salt, pepper, and sugar.Stir in a handful of chopped basil or parsley if you like. Serve with spaghetti, crusty bread, or in hoagie rolls with melted provolone.

FAQ
Do I have to brown the meatballs first?
Browning adds flavor and helps the meatballs hold their shape, but it’s not mandatory. You can place raw meatballs directly in the slow cooker with the sauce.
If you skip browning, cook on Low and avoid stirring for the first couple of hours.
Can I use store-bought frozen meatballs?
Yes. Add them frozen and cook on Low for 6 to 7 hours or High for 3 to 4 hours, depending on your slow cooker. The flavor won’t be as homemade, but the sauce will still be delicious.
How do I keep meatballs from falling apart?
Use the eggs and panade for binding, and avoid overmixing.
Brown gently and don’t stir too much early in the slow cook. If your mixture seems very loose, add a few extra tablespoons of breadcrumbs.
What pasta pairs best with these meatballs?
Classic spaghetti is great, but bucatini, rigatoni, or pappardelle work well too. Thick sauces cling nicely to ridged or wider noodles.
How can I make the sauce smoother?
Use one jar of marinara with one can of crushed tomatoes, or blend the sauce with an immersion blender before adding the meatballs.
You can also simmer the sauce in the skillet a few minutes to meld flavors before pouring it in.
Can I cook this overnight?
It’s better to cook during the day so you can check for doneness and seasoning. If you need to cook while you sleep, use the Low setting and a smart plug or a slow cooker with a timer that switches to Warm when done.
What internal temperature should the meatballs reach?
Aim for 160°F for beef and pork, or 165°F if using poultry. A quick-read thermometer takes the guesswork out and prevents overcooking.
How can I lighten the recipe?
Use turkey, reduce the Parmesan to 1/2 cup, and serve over spaghetti squash or zucchini noodles.
You can also skim extra fat from the top of the sauce after chilling.

Slow Cooker Italian Meatballs deliver big, comforting flavor with minimal effort. A few smart steps—like a simple panade, gentle mixing, and slow simmering—give you tender meatballs and a rich, savory sauce. Keep a batch in the freezer for busy nights, and you’re never far from a cozy dinner.
