French Onion Grilled Cheese Sandwiches

French onion soup is bomb-we all know that-but sometimes you need the same flavors in a portable format ASAP.  That’s where a French onion soup grilled cheese comes in to save the day.  Especially when we have some amazing tomato soup to dip it in (coming tomorrow).I made a fantastic French onion soup recipe from Petit Trois restaurant, and while I highly suggest making it when you have a leisurely day at home, it’s definitely not the kind of thing you can whip up on a whim and sit down to eat within an hour.  It involves making your own veal stock, slowly caramelizing onions, and bringing it all together to simmer before broiling it with its cheesy top.

This sandwich is the antidote to that!  While you do have to spend the time to caramelize the onions, it’s mostly hands-off with the exception of a little stirring.  Once the onions are caramelized, you bring them together with Gruyere cheese, a little fresh parsley and a few slices of bread.  Griddle in the skillet to get that ooey-gooey, melted cheese combination with crisp bread and you’re ready to go!  Consider all of your French onion soup cravings handled with this sandwich.

Instructions

1. In a large, heavy-bottomed pan, melt the butter over medium-low heat.  Add the onions and sprinkle with salt.  Cook, stirring occasionally, until golden and caramelized, about 40 to 50 minutes.
2. Heat a large nonstick skillet or griddle over medium heat.  Combine the mayonnaise and butter and mash together until fully combined; stir in the 1/2 teaspoon chopped thyme.  Spread one side of each piece of bread with this mixture.  Flip the bread over to the unbuttered side and place 1/4 of the cheese on two slices.  Place half of the onions on each top and the remaining cheese and parsley.  Top with the second piece of bread.  Transfer the sandwiches to the preheated skillet and cook until golden brown and the cheese is melted, about 5 to 6 minutes per side.
