Ingredients You’ll Need
For the ultimate cheesy and creamy potato dish, the ingredients must be fresh and of good quality. Here’s what you’ll need:
- 4 medium-sized potatoes (preferably russet or yukon gold for the best texture)
- 2 cups heavy cream (to make a sauce that is thick and smooth)
- 1 cup whole milk (to balance the cream and add some lightness)
- 2 cups grated cheese (Gruyère and sharp cheddar are excellent choices for a good melt and flavor)
- 3 tablespoons butter (for richness and to help with the creamy texture)
- 2 cloves garlic, minced (for added flavor)
- Salt and pepper (to taste)
- 1 teaspoon fresh thyme (optional for added fragrance)
- Grate 1/4 cup of parmesan cheese on top to make it golden and crispy.
- 1 tablespoon flour (to thicken the sauce)
- Fresh parsley (optional, for garnish)
Step 1: Prepare The Potatoes
You can peel the potatoes first if you want to, but leaving the skin on can make the texture better and add extra nutrients. Slice the potatoes evenly into thin rounds, about 1/8-inch thick. The thinner the slices, the better the potatoes will absorb the creamy sauce, resulting in a smooth and consistent texture.
It’s important to slice the potatoes evenly to ensure they cook uniformly. To get really precise cuts, you can use a mandoline slicer. If you don’t have one, you can carefully cut them by hand.
Step 2: Make The Creamy Sauce
Put the butter in a medium-sized saucepan and melt it over medium-low heat. This will make the signature creamy sauce. Add the minced garlic after the butter has melted and cook for about one minute, until the garlic smells good. Next, add the flour to the butter and garlic mixture and stir it all the time for about two minutes. This turns the sauce into a roux, which makes it thicker.
Pour the heavy cream and milk in slowly while stirring all the time to avoid lumps. Keep cooking over low heat until the sauce gets as thick as you like it. Add fresh thyme, salt, and pepper, if you want. Mix the sauce and cheese together until they are fully mixed. This will form the rich, velvety base that coats the potatoes.
Step 3: Layer The Potatoes And Sauce
Start by getting the oven to 375°F (190°C). Put cooking spray or butter on a baking dish to make it smooth. Place the sliced potatoes in the dish in layers, making sure that each slice overlaps a little. Add some of the creamy cheese sauce on top of the first layer of potatoes. Repeat the process, layering the potatoes and sauce until all the ingredients are used up. Be sure to finish with a generous layer of cheese sauce on top.
Step 4: Bake The Dish
For about 45 minutes, bake the potatoes with the foil over the dish. Take the foil off and bake for another 15 to 20 minutes, or until the top is golden brown and crunchy. You should be able to easily poke holes in the potatoes with a fork. If you like your top extra crispy, you can broil the dish for 2-3 minutes, but be sure to watch it carefully to prevent burning.
Step 5: Serve And Enjoy
If you want to serve the dish right away, take it out of the oven and let it cool for about 5 minutes. This will give the sauce time to set, making it easier to serve in neat slices.
Adding chopped parsley that you just picked will add color and make it taste even better. Serve the dish alongside roasted meats, a crisp salad, or as a comforting standalone meal.
