How do you keep meatball subs from getting soggy?

In order to make the best meatball sub possible you need to make sure you assemble these as you are ready to eat them. I start by toasting the roll for a minute or two, topping with the warmed sauce and meatballs, top with cheese, and bake in the toaster oven at 350 for 4-8 minutes.

How long are the meatballs subs good for in the fridge?

If you are making these meatballs in advance, store the meatballs and the rolls separately and assemble them as you are going to eat them, otherwise, they will get soggy (see above). They will last a week in the refrigerator and a month in the freezer.

What if you are gluten-free?

If you are gluten-free unfortunately I do not have many swaps or changes for this recipe since the french onion mix contains wheat, but if you want to omit this and find gluten-free bread crumbs and gluten-free buns then you can make it work!

Can you add the french onion meatballs to other dishes?

Yes! If you want to just make the meatballs and add them to other dishes they would be great! I think they would taste amazing in a beef broth with egg noodles, or with sauteed mushrooms and gravy!
