Ingredients
Scale
Main Ingredients
- 2 pounds Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
- 2 cups sharp cheddar cheese, shredded
- 2 cups heavy cream
- 3 tablespoons butter
- 3 cloves garlic, minced
- 1 medium onion, diced
- Salt, to taste
- Freshly ground black pepper, to taste
- 1/2 cup Parmesan cheese, grated
Instructions
- Prepare and slice the potatoes: Wash and peel the Russet potatoes. Using a mandoline slicer or a sharp knife, cut them into thin, even slices about 1/8 inch thick to ensure uniform cooking.
- Sauté the aromatics: Melt the butter in a skillet over medium heat. Add the minced garlic and diced onion, cooking for 3–4 minutes until softened and fragrant, forming the flavorful base of the cheese sauce.
- Make the cheese sauce: Pour the heavy cream into the skillet with the garlic and onions, stirring as it warms. Gradually incorporate the shredded sharp cheddar cheese until fully melted and smooth. Season the sauce with salt and freshly ground black pepper to taste.
- Layer the potatoes and sauce: Grease a baking dish and arrange a layer of the thin potato slices evenly in the dish. Pour a portion of the cheese sauce over the layer to coat generously. Repeat layering potatoes and sauce, finishing with sauce on top.
- Add the topping: Evenly sprinkle the grated Parmesan cheese over the final sauce layer to create a golden, crispy crust during baking.
- Bake until bubbly and golden: Preheat the oven to 350°F (175°C). Bake the dish uncovered for 55 to 65 minutes until the potatoes are tender when pierced and the top is bubbling and golden brown.
Notes
- Slice potatoes uniformly thin for even cooking and a creamy texture.
- Bake low and slow to prevent drying out and allow flavors to meld.
- Use freshly shredded cheese instead of pre-shredded for better melting and richer flavor.
- Let the dish rest for 10 minutes after baking to set, making it easier to serve.
- For an extra crunchy topping, mix breadcrumbs or crushed crackers with Parmesan cheese before sprinkling on top.
