French Onion Meatball Sub

Some flavor profiles are just undeniably good. They are considered classics because they just work over and over again. French Onion Soup is one of those classic flavor profiles that has stood the test of time. And it has been re-invented in many ways to make different dishes – like this French Onion Meatball Sub!

You might look at the ingredients list and bristle at pork rinds – but hear me out! Pork rinds are an amazing substitute for bread crumbs. They add to the meaty flavors of the meat, they bind it together just as well – AND they keep it keto! Since I was using half pork and half beef – it really just added to the great flavor of these meatballs. You might also notice that I put cheese IN the meatballs and ON the meatballs. That is to give the feel of that delicious cheesy layer of goodness you find on a tradition French Onion Soup.

This is a perfect dish to make when some people in your family are Keto and some are not. The keto peeps can eat the meatballs on their own and the non-keto peeps can pile them high a toasted crusty sub roll! That’s win-win.

You absolutely must toast your sub rolls for this sandwich. The meatball and onion filling is “wet” so it will soak into untoasted bread quickly and leave you with a mushy mess. The simple act of toasting the buns, makes for a much more pleasant dining experience.
