Ingredients You Will Need

• Russet potatoes, thinly sliced. These bake up soft and soak in all that creamy sauce.
• Butter. Adds rich flavor and helps create a smooth base.
• Flour. Thickens the sauce so it coats every layer.
• Whole milk. Makes the sauce creamy and comforting.
• Sharp cheddar cheese. Melts beautifully and gives that classic cheesy flavor.
• Garlic. Just a little for warmth and depth.
• Salt and black pepper. Simple seasoning that lets the potatoes shine.

Step by Step Instructions

1. Preheat your oven to 375 degrees. Lightly grease a baking dish with butter.
2. Peel and slice the potatoes into thin, even rounds. Try to keep them the same thickness so they cook evenly.
3. In a saucepan over medium heat, melt the butter. Stir in the flour and cook for about 1 minute until smooth.
4. Slowly pour in the milk, whisking as you go. Cook until the sauce thickens, about 3 to 5 minutes. Add garlic, salt, and pepper.
5. Stir in half of the shredded cheese until melted and smooth.
6. Layer half of the sliced potatoes in the baking dish. Pour half of the sauce over them. Repeat with the remaining potatoes and sauce.
7. Sprinkle the rest of the cheese on top.
8. Cover with foil and bake for 40 minutes. Remove the foil and bake another 20 to 25 minutes, until the top is golden and the potatoes are tender when pierced with a fork.
9. Let it rest for 10 minutes before serving so the sauce can settle.
