These Easy Slow Cooker Meatball Subs are the perfect dinner idea for busy nights. The best part is, you can use frozen meatballs and a couple of other pantry staples, and you’ll have a satisfying dinner on the table with less than 5 minutes of prep work!
My slow cooker has been getting quite a workout lately with our busy weeknight schedule. My son is currently attending a martial arts program after school a few days a week. He has to be picked up by 6 pm, which is right in the middle of when I’m normally be prepping dinner. So having dinner already going in the slow cooker has been a lifesaver to me these last few weeks.
The entire family loves these meatball subs! They are so easy to make in the slow cooker. I use premade frozen meatballs, but if you had extra time, you could make your own as well. I promise, it doesn’t get easier than chopping up an onion, dumping a bag of meatballs and a jar of your favorite spaghetti sauce in the slow cooker. (Don’t forget to use a liner, so cleaning is quick and easy too!)
These stay in the slow cooker for a few hours which means I can toss everything together in the slow cooker when the Missy and I are having snacks and it’s ready to eat when I get back from picking my son up from his martial arts class.
I like to use small rolls for these – there are about 3 to 4 meatballs on each sandwich which helps reduce the risk of spaghetti sauce stained clothes (and spaghetti hair) since they’re much easier to hold and eat. You could also just put them in a bowl and eat them with a fork. (Which is what I may or may not do, lol!)
Though you can’t really tell from pictures, the subs are CHEESY. We love cheese around here and it’s not a meatball sub without some cheese. I put the cheese under the meatballs so it melts right into the bread. We like ours extra cheesy, but you can put as much or as little cheese as you’d like on your subs.
These are definitely going to be a weeknight staple during going forward! Check out the rest of my slow cooker recipes here.
