1 tablespoon butter
1 1/4 pounds russet potatoes, peeled and sliced 1/8th inch thick
1/2 medium onion, minced
1 clove garlic, minced
1/2 tablespoon fresh thyme, chopped
1/2 cup chicken broth
1/2 cup heavy cream
1 bay leaf
2 ounces grated cheddar cheese
Salt and pepper
1. Preheat the oven to 425ºF. Heat a large iron skillet over medium-high heat. Add the butter. When melted, add the onion. Cook for 4 minutes, or until soft.
2. Toss in the garlic and thyme, and cook for 30 seconds or until fragrant. Add a pinch of salt and pepper. Dump in the potatoes, chicken broth, cream, and bay leaf. Bring to a simmer and then cover, reduce heat to medium-low, and cook for 10 minutes.
3. Remove the cover, sprinkle the cheese on top, and place the iron skillet in the oven. Cook for 15 minutes, or until the cheese is bubbling and slightly browned. Let rest for 5-10 minutes before serving. Season with salt and pepper to taste.
