My husband and I recently bought a grill, and have been so excited to use it. We spent the last two years without one and missed it much more than we thought we would. Now that we have a yard, and it’s actually been nice out, we are taking full advantage. I’m one of those people who thinks anything can and should be grilled. Fruit, veggies, meat, bread, cheese in bread.. Which leads me to the subject of this post – a French Onion Grilled Cheese Sandwich. It is heaven.
French Onion soup is one of my favorite things about cold weather. I feel entitled to ordering it and making it as much as possible. I mean who can resist soup that has an entire layer of melted cheese?! The sandwich version of the soup is surprisingly simple. The only time consuming part is caramelizing the onions.
Normally I make my grilled cheese on the stove, but since I love grilling, I figured why not grill on the grill, and gave it a go. I should also mention I am a serious sucker for grill marks. I mean just look at these beauties:
One of the things I love most about French Onion Soup is how packed with onions it is. I wanted to emulate that in the sandwich, so I used an entire onion. The end result was a nice thick layer of caramelized onions. If you think a whole onion is overload, feel free to split it between two sandwiches or save the leftover in the fridge and reheat when you are ready to use.
Okay, now that I’ve hopefully convinced you to make this sandwich, here is the recipe:
French Onion Grilled Cheese Sandwich
- 1 tbsp olive oil
- 1 garlic clove, minced
- 1/2 tsp thyme
- 1 large yellow onion, (about 1 1/2 c) sliced in to strips
- 1 tbsp flour
- 2/3 c beef broth
- salt & pepper to taste
- 2 slices bread, buttered on one side
- 2 oz Gruyere cheese, sliced
- Add the olive oil, garlic, and thyme to a medium pan and caramelize on low heat for about 25 minutes, stirring occasionally.
- When the onion is a nice golden brown, add the flour and coat the onion evenly.
- Cook for about another five minutes, and continue to stir.
- Bring the heat up to medium and add the broth a little at a time, stirring constantly. The broth should thicken when you mix it in to the onions. Continue to add the broth until the mixture is a thick sauce.
- Take off the heat, and set aside.
- Place one of the pieces of bread, buttered side down on a plate, and layer your cheese on top of the bread.
- Spoon the onion mixture on top of the cheese, and spread evenly.
- Place the other piece of bread, butter side up on top of the onion.
- Place the sandwich on the grill or on a pan and heat over medium heat until the bread on the bottom has browned. Flip the sandwich and continue heating until the other side has browned.
- Take off the heat, and serve!
If you are making the sandwich on the grill, place on an upper rack, and put a piece of foil underneath on the bottom rack to catch any drippings. Toward the end, remove the foil to get the nice grill marks. This method takes longer, but provides for a cleaner grill.
