Ingredients
-
3 tablespoons butter
-
3 tablespoons olive oil
-
6 white onions, sliced into thin rings
-
1 clove garlic, minced
-
1 pinch salt, plus more to taste
-
1 ½ teaspoons ground black pepper, plus more to taste
-
1 tablespoon brown sugar
-
1 tablespoon dried thyme
-
⅓ cup port wine
-
1 (32 ounce) carton beef stock
-
5 slices French bread
-
5 slices Swiss cheese
-
¼ cup shredded Parmagiano-Reggiano cheese
Directions
-
Melt butter with olive oil in a large pot over medium-low heat. Add onions and garlic; season with a pinch of salt and black pepper. Cook onion mixture in hot butter-oil until caramelized, stirring every 10 minutes to keep from browning too quickly, about 1 hour.
-
Stir brown sugar and thyme into caramelized onions; allow sugar to melt into onions, about 2 minutes. Pour in wine and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon; continue simmering for 5 more minutes. Pour in beef stock; cook for 10 more minutes. Season soup with salt and pepper.
-
Preheat the oven's broiler to high. Place 5 oven-safe crocks onto a baking sheet.
-
Ladle soup evenly into the crocks. Top each with a French bread slice; cover with a Swiss cheese slice and sprinkle with Parmagiano-Reggiano cheese.
-
Cook soups under the preheated broiler until cheese is melted and browned, 2 to 3 minutes.
