These meatball subs require a bit of extra time in the kitchen, but the results are so worth the effort. The meatballs are absolutely phenomenal, and 100% worth the time it takes to make them from scratch. I like to make the meatballs and sauce ahead of time, then keep everything warm in a slow cooker until I’m ready to assemble the subs.
We like our meatball subs spicy, so we use hot Italian sausage, along with the red pepper flakes in the sauce, but using mild sausage and no red pepper flakes offers just as much flavor with a little less heat. If you like your cheese nice and brown, turn on the broiler for the last few minutes the subs are in the oven. These are a huge family favorite and Super Bowl Sunday will be the perfect excuse to make them again.
