Preparation Steps

  1. 1

    Prepare the Onions

    Peel and slice the onions thinly. In a large skillet, melt the butter over medium heat. Add the onions and cook until they are soft and caramelized, about 20 minutes.

  2. 2

    Add Garlic and Broth

    Stir in the minced garlic and cook for an additional 2 minutes. Pour in the broth, thyme, salt, and pepper. Simmer for 10 minutes to blend the flavors.

  3. 3

    Prepare the Baguette

    While the soup simmers, preheat the broiler. Arrange the sliced baguette on a baking sheet and toast under the broiler until golden brown, about 2-3 minutes.

  4. 4

    Assemble the Gratin

    Ladle the onion mixture into oven-safe bowls or ramekins. Top each bowl with a slice of toasted baguette and sprinkle generously with Swiss cheese.

  5. 5

    Broil the Gratin

    Place the bowls under the broiler for 3-5 minutes, or until the cheese is melted and bubbly. Keep a close eye to prevent burning.

  6. 6

    Serve

    Carefully remove the gratin from the oven and let cool for a few minutes before serving. Enjoy your Murphy's Irish Onion Gratin!
