Servings: 6
Calories: 345kcal
Ingredients
- 2 cups heavy cream
- 1 teaspoon kosher salt
- 2 tablespoons minced garlic
- 2 tablespoons butter salted
- 1 teaspoon dried minced onion
- 6-7 medium potatoes
- ½ cup grated Parmesan cheese
- 1 teaspoon parsley
Instructions
- Preheat the oven to 325°F (163°C). In a small saucepan over low heat, combine the heavy cream, salt, and minced garlic. Heat until simmering for 5 minutes, allowing the garlic flavor to infuse into the cream. Remove from heat and set aside.
- Rinse the potatoes before using a mandolin slicer to thinly slice potatoes into ⅛-inch thicknesses. In a 16-inch cast iron skillet, brown the butter for 4 minutes until slightly golden. Add the minced onion for the last minute. Remove from heat and set aside.
- Arrange the sliced potatoes in a spiral pattern on top of the browned butter in the cast iron skillet. Pour the garlic cream over the sliced potatoes.
- Cover the cast iron pan tightly with tin foil and place it in the preheated oven. Bake for 1 hour and 15 minutes. Remove the skillet from the oven and switch the oven to the broil setting. Sprinkle the Parmesan cheese over the potatoes. Add the parsley as well.
- Return the skillet to the oven and broil for 3-5 minutes or until the cheese becomes crispy and starts bubbling. Take the pan out of the oven and serve the potato dish while it's still warm.
Notes
- Use a mandoline slicer to keep all potato slices the same thickness for even cooking.
- Allow the garlic to gently simmer in the cream to maximize flavor without scorching!
- Cover the skillet tightly with foil to keep moisture inside during baking and test the potatoes with a knife before broiling to ensure they're fully tender.
- Watch carefully during broiling since Parmesan can go from golden to burnt quickly!
- Let the potatoes rest for 5 minutes before serving to allow the cream sauce to thicken slightly.
