Grilled French Onion Soup

March 13, 2014

Nothing beats a warm bowl of soup on a cold winter day and the oozy cheesy goodness of this grilled and broiled French oven soup is a great choice.  Unlike traditional French onion soup, this version features grilled onions, adding a deep smoky flavor to the soup.  It also employs a makeshift broiler for the grill (check out the “how to” here) which is key for getting the cheese topping bubbling and brown.

5 medium white onions, thinly sliced

½ tbsp. extra virgin olive oil

32 ounces beef broth

½ tsp. ground thyme

2 cloves garlic, pressed

¼ cup red wine

3 tbsp. butter

4 slices French bread, toasted

8 ounces grated Swiss cheese

Salt and pepper to taste



Prepare grill for medium-high heat grilling (approximately 350 degrees), placing a grilling basket on the main grate to preheat.  In a medium mixing bowl, toss onion slices with olive oil.  Place onions in the grilling basket and allow the onions to cook for approximately 10 minutes, stirring every 2 minutes until the onions are soft and lightly browned.

Remove the onions from the heat and place in a large saucepan along with the beef broth, ground thyme, garlic, and red wine.  Place the saucepan on the grill and allow the mixture to simmer for 15-20 minutes until fully heated.  Remove the soup from the heat, whisk in the butter.  Ladle the soup in to 4 heat resistant soup bowls then top each one with a slice of French bread and an even portion of grated Swiss cheese.
