I guess the beef broth makes a change in consistency. Otherwise, it just seems like lasagna ingredients assembled differently.
My wife can’t eat most cheeses cause of an allergy. So we make a basic meat sauces and then layer the noodles in one pan. For my daughter and me, we make a second pan and add some shredded cheese, mozzarella or a provolone mix.
Yes the broth would make it more fluid - there is a soup served at Olive garden that is basically this base but with some veggies added - very good flavor.
