Additional Ingredients

Method

Caramelize the Onions

  1. 1

    Prepare the Onions

    Peel and thinly slice the medium onions.

  2. 2

    Cook the Onions

    In a large skillet, heat the butter and olive oil over medium heat. Once melted, add the sliced onions, sugar, and salt. Stir to coat the onions.

  3. 3

    Caramelize

    Cook the onions for about 20-25 minutes, stirring occasionally until they are golden brown and caramelized. Remove from heat and set aside.

Assemble the Sandwich

  1. 4

    Prepare the Cheese

    Grate the Gruyère, Fontina, and Mozzarella cheeses and mix them in a bowl.

  2. 5

    Spread Butter

    Butter one side of each slice of sourdough bread.

  3. 6

    Add Cheese and Onions

    On the unbuttered side of two slices, sprinkle half of the cheese mixture, add a generous portion of caramelized onions, and then top with the remaining cheese mixture. Cover with the other slices of bread, buttered side facing out.

Grill the Sandwich

  1. 7

    Heat the Skillet

    In the same skillet, heat over medium heat.

  2. 8

    Cook the Sandwich

    Place the assembled sandwich in the skillet. Grill for about 3-4 minutes on each side or until the bread is golden brown and the cheese is melted.

  3. 9

    Serve

    Once done, remove from the skillet, slice in half, and serve hot. Sprinkle with garlic powder and black pepper if desired.
