Who out there absolutely loves French Onion Soup? I think it is one of my favorite soups and I love that crostini on top with melted gruyere. So damn good. When I tried a french onion grilled cheese sandwich a few years ago, it blew my mind. It's all the flavor of french onion soup, but in a sandwich... with bacon. Or no bacon if you're a vegetarian. They weren't too common a few years ago, but I think they're gaining popularity.
French Onion Soup on a Sandwich? Yes, please!
Okay, last week I jumped off my high-quality bread soapbox and flat-out told you to buy store-brand white bread for my Delicious Crispy Thai Pork Toast. Well, I'm climbing back up to say: please use high-quality bread for this sandwich. It makes a world of difference. I used the same kind of bread that I used for my Croque Monsieur (aka The Best Ham & Cheese Sandwich You'll Ever Eat). It's from a local bakery (always a good start). It's called Nashoba Brook Bakery - located in Concord, MA. You can buy bread at their bakery or at a local Hannaford. If you're outside New England, try to use bread from your favorite local bakery.
French onion soup wouldn't be the same without melted gruyere cheese on the top. And as you can imagine, French onion grilled cheese will not be the same without it. I don't usually see this cheese already shredded at the grocery store. You need to buy a small block and shred it yourself. It's all part of the fun!
Adding thick-sliced bacon to this sandwich puts it over the top. You can easily start cooking your bacon while your onions are caramelizing in the other pan. Of course, if you're a vegetarian just skip the bacon. This sandwich tastes fantastic either way. Right at the end of cooking your onions, you'll add a few tablespoons of port wine to give it that brothy flavor just like the soup. Works every time!
This French onion grilled cheese is a guaranteed hit and so easy to put together. This recipe is for two sandwiches but you can use the recipe multiplier to make it for a larger crowd.
If you do make this sandwich, tell me all about it in the comments below. And remember: enjoy your time in the kitchen. Prepare delicious foods for yourself and your loved ones. You are all worth it.Print
