This brilliant mash-up combines the flavors of French onion soup with matzo balls. Dave Mechlowicz mixes caramelized onions into the dough and then stuffs them with Gruyère cheese. They'll turn into fluffy dumplings with a gooey surprise in the middle.
This warm and cheesy dip as all the makings of a bowl of French Onion Soup -- but with even more cheese! Serve it with toasted bread for dipping, just like you'd find on top of the iconic soup.
Everyone orders French onion soup for the gooey cheese topping and, most of all, the crunchy-crispy edges. Marc Murphy drapes a piece of cheese over this burger so it melts onto the pan and caramelizes.
