French Onion Soup Grilled Cheese
Ingredients
1 large onion, thinly sliced (about ⅛-inch thick)
1 tablespoon olive oil
¼ teaspoon salt
Pinch of dried thyme
Pinch ground black pepper
4 tablespoons beef stock (use vegetable stock to keep it vegetarian)
4 slices of bread (hearty bread preferably whole grain)
1 tablespoon butter
¾ cup grated Gruyère cheese (or Emmental cheese or Swiss cheese)
Chopped fresh parsley
Directions
Caramelized onions
Heat oil in a heavy bottom pan (or cast iron skillet). Add onions and cook, stirring until they soften, about 5 minutes. Add a generous pinch of salt, thyme, and pepper and turn the heat to low. Add beef stock and cook, stirring every now and then, until onions are soft and golden brown, about 20 to 30 minutes. Season to taste with salt and pepper and remove from pan.
Wipe the pan with paper towel and set aside.
Assemble grilled cheese
Butter one side of each slice of bread (preferably the top part) with remaining butter.
Place one slice of bread in the pan, buttered side down, sprinkle with 2 tablespoons of grated cheese top with half of the caramelized onion, then another 2 tablespoons of grated cheese, sprinkle with parsley, and top with another bread slice, buttered side up.
Turn the heat down a notch and cook until golden brown, about 2 to 4 minutes.
Gently flip and cook until golden brown on the other side, about 2 to 4 minutes.
Repeat procedure to make the other grilled cheese sandwich.
