Ingredients

  • 2 tablespoons olive oil
  • 2 cups beef broth (or vegetable broth for a vegetarian option)
  • 1 cup heavy cream

Step-by-Step Instructions

Creating the French Onion Potato Bake is a straightforward process. Follow these steps to ensure a delectable outcome:

  1. Preheat your Oven: Start by preheating your oven to 375°F (190°C).
  1. Caramelize the Onions: In a large skillet, heat olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are soft and golden brown, about 20-25 minutes.
  1. Add Garlic and Thyme: When the onions are caramelized, stir in the minced garlic and dried thyme. Cook for another 2-3 minutes until fragrant.
  1. Combine Broth and Cream: In a large bowl, whisk together the beef (or vegetable) broth and heavy cream. Season with salt and pepper.
  1. Layer the Bake: In a large baking dish, layer half of the sliced potatoes at the bottom. Top with half of the caramelized onion mixture and sprinkle with half of the Gruyère and mozzarella cheese.
  1. Repeat Layers: Add the remaining potatoes, followed by the remaining caramelized onions. Pour the broth and cream mixture evenly over the top, ensuring the potatoes are well covered.
  1. Add Cheese: Top with the remaining Gruyère and mozzarella cheese.
  1. Cover with Foil: Cover the baking dish with aluminum foil, ensuring it is tightly sealed to retain moisture.
  1. Bake: Place the covered dish in the preheated oven and bake for 45 minutes.
  1. Remove the Foil: After 45 minutes, remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is bubbly and golden brown.
  1. Garnish: Once baked, let the dish cool for about 10 minutes. Garnish with freshly chopped parsley before serving.

By following these steps diligently, you’ll create a stunning French Onion Potato Bake that’s sure to impress all who taste it.

  1. Garnish for Flavor: A sprinkle of chopped fresh parsley or even some crispy fried onions on top can provide an appealing finish and add extra flavor.

  • Bake in Smaller Portions: For individual servings, consider dividing the layers into smaller ramekins to create personal-sized bakes that are perfect for sharing.
