I love home made Patty Melts, you get to control exactly what's in it and make it how you like it! I actually haven't made Patty Melt's for awhile, I think of it as more of a fall or winter food, but saw a post about them on The Pioneer Woman that is crazy similar to how I make them!
approx 1lb of ground beef
salt & pepper to taste
cheese slices (I use mozzarella)
1 white onion, sliced
sliced bread (I use sourdough and bakery type white bread)
I start with slicing up the onion, adding them and some butter to a small sauce pan, cook them on low until caramelized.
Unlike making a burger with filler like bread crumbs and eggs, for patties I just use ground beef, salt and pepper and some Worcestershire sauce. Mix then form into patties, I make them as thin as I can.
Fry up the patties until cooked through.
Make your sandwich by buttering the outside of your bread slice, put a piece of cheese, then a patty, then onions, another piece of cheese and another slice of bread buttered on the outside.
Fry until golden brown on both sides, don't flip too early on the first flip or the whole thing will fall a part, I won't tell you how I know that ;-)
Everyone loves this, including the kiddos (I don't include the onion on theirs). The norm is to use swiss cheese in a patty melt but we like the mozzarella better, same with liking sour dough and white bread over the rye. Delish!!!!
