I love Onion Soup. Traditionally, it is made with beef broth and has grilled bread covered with melted cheese that gets all gooey and drips down your mouth, sitting on top of it. You can’t do that if you’re kosher. I decided to make a vegetarian version, so I can make it for both meat and dairy meals. I can still grill a slice of a baguette, and place it on top of the hot soup- or just eat it plain. It is that delicious. If you’re having a dairy meal: grill slices of a baguette and cover them with gruyere. Place one slice on top of each crock and place them under the broiler. Use a kitchen torch to melt the cheese if your crocks can’t go in the oven. This is a real treat!

Prep: 15 minutes

Note: Onions take a longer time than you might imagine to caramelize. Don’t be impatient. First, they have to give up their natural juices before the sugar in them can begin to turn the slices golden brown. The flavor is worth the wait!
