Let’s Make it together
Preheat your oven to 375°F (190°C). Grab an 8×8-inch baking dish and generously butter it so nothing sticks later on.
Layer those Potatoes!: Thinly slice about 4-5 russet potatoes using a mandoline or sharp knife until they are around 1/8 inch thick. Aim for uniform slices to ensure even cooking.
Mix Your Creamy Goodness!: In a bowl, whisk together 1 cup of heavy cream with 1 teaspoon garlic powder, 1 teaspoon salt, and half a teaspoon of pepper until well combined. This will be your flavor-packed sauce.
Create Layers!: Begin layering half of your sliced potatoes neatly in the bottom of your prepared baking dish. Pour half of your cream mixture over them evenly before sprinkling half of your shredded sharp cheddar on top.
Add More Layers!: Repeat the layering process with the remaining potatoes, cream mixture, and cheddar cheese until you finish all ingredients—this creates that dreamy layered effect.
Bake Away!: Cover with aluminum foil (shiny side up) and bake for about 45 minutes. Remove foil and bake for an additional 15-20 minutes until golden brown and bubbly on top. You’ll know it’s done when you see those gorgeous crispy edges!
Let it cool slightly before serving; patience is key! This will allow those cheesy layers to set perfectly.
Now you’re ready to dive into a plateful of creamy potato au gratin goodness! Enjoy every bite as those flavors meld together beautifully—comfort food at its finest!
