One of the first things I learned about my husband after we got married is that he loves French Onion Soup. He'll often order it when we go out to eat, and he even loves the frozen kind that Costco sells. So when I saw this recipe, I knew I had to give it a try! It's a keeper! Next time I'll double the recipe. No leftovers makes me sad.
Thanks, Tasty Kitchen
French Onion Soup Sandwich
3 Tablespoons butter, and some more to butter bread
1 Tablespoon Olive Oil
2 whole medium yellow onions, sliced 1/4" thick
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon sugar
1 teaspoon fresh Thyme leaves
3 Tablespoons of Beef Broth
1/2 cups grated cheese (Gruyere or Provolone)
Sourdogh bread, sliced
In a large skillet over medium heat, melt the butter and olive oil together. Add onions and stir so they are all coated. Cook undisturbed for about 5 minutes.
Stir and add in the salt, pepper, sugar and Thyme. Stir, cover the pan and let cook. Stir occasionally until the onions are soft and deep golden color. Reduce the heat if onions are browning too soon.
Add in the beef stock and scrape any bits of the bottom of the pan. Remove from heat.
On a griddle or skillet, preheat and then place buttered bread (buttered side down) and top it with cheese. Add some onion mixture and more cheese. Top with another slice of bread.
Cook and flip.
