How to Make Meatball Subs in the Crockpot
Whether you make the meatballs the night before and turn the crockpot on in the morning or do it all at once the same day, coming home to a great-smelling kitchen and a dinner ready to be eaten is the best feeling ever! Here is what you’ll be doing:
- Make a base layer
Chop the onion and add it to the bottom of your slow cooker dish.
- Prepare the meatballs
Combine the ground meat, bread crumbs, eggs, and seasonings in a large bowl. Once the mixture is cohesive, roll it into 16 golf-sized meatballs.
- Set to cook
Stack the meatballs in an even layer in the slow cooker and top them with the tomatoes and pasta sauce. Cover with lid and cook for 3-6 hours.
Slice or fold open each hoagie roll, sprinkle a little cheese at the bottom, and top with meatballs and some sauce. Sprinkle additional cheese and enjoy.
How many Meatballs Per Sub?
Depending on the meatball size, a typical hoagie sub can fit 3 to 4 of them lined up from end to end.
Make Ahead Tips
Meatball recipes like this one can be fully prepped ahead by making the meatballs, placing them inside the slow cooker with the other ingredients as noted in the recipe and then refrigerated overnight covered with plastic wrap.
In the morning, all you have to do is remove the bowl of the slow cooker from the refrigerator, place it inside the crockpot, and set it to cook.
By dinnertime, you’ll have a delicious dinner waiting for you!
Doubling and Tripling the Recipe
You can double or triple the meatball recipe for gatherings, extra guests, or freezing. Grab a larger bowl and get rolling.
You can freeze these uncooked on a lined sheet pan, and once frozen, transfer them to a zip bag and kept frozen for up to 3 months. When you’re ready for fresh meatballs, take however many you need out of the freezer, put them in the slow cooker with sauce, and you’re ready to go.
How to Store Leftovers
Once cooled, you can store leftover meatballs in an airtight container or zip bag in the refrigerator for up to 5 days. Alternatively, you can freeze them with sauce for up to 3 months.
Avoiding Soggy Buns
While soggy buns can put a damper on your sub-enjoyment experience, there are several easy things you can do to prevent this.
Toast the subs
A toasty bread top layer will help retain the integrity of the bun by preventing the meatball sauce from seeping down.
Make a layer of cheese
Instead of topping the subs with all the cheese, distribute some of it under the meatballs. With the heat, the melty later will also make a barrier between the cheese and the bread. You can also use sliced cheese.
Don’t let the assembled subs sit out longer than necessary since this gives the bread time to soak up the sauce.
