Tips & Tricks
- Use frozen meatballs to save time and still get great flavor.
- If sauce seems thin, remove lid for the last 30 minutes to reduce and thicken.
- Toasting the rolls first prevents them from getting soggy under the sauce.
- Watch the broiler closely; cheese melts fast and can burn in seconds.
- For more depth, brown fresh meatballs in a skillet before adding to the crockpot when you have a bit more time.

- Game day platter with extra marinara for dipping

Frequently Asked Questions
Can I use homemade meatballs in the crockpot?
Yes, homemade meatballs work well, just brown them quickly in a skillet first for extra flavor, then add to the crockpot with sauce.
How do I prevent the rolls from getting soggy?
Toast or lightly broil the rolls before adding meatballs and sauce to create a barrier that limits sogginess.
Can I freeze assembled subs for later?
It is best to freeze the meatballs and sauce separately, store in airtight containers up to 3 months, and thaw then assemble and broil the rolls when ready.
