Let’s Make it Together
Preheat Your Oven: Begin by preheating your oven to 375°F (190°C). This temperature helps achieve that golden, bubbly top we all adore.
Prepare the Baking Dish: Lightly grease your baking dish with butter or cooking spray. This will prevent sticking and enhance the crust’s browning.
Slice the Potatoes: Thinly slice your russet potatoes using a mandoline or sharp knife. Aim for uniform slices around 1/8 inch thick for even cooking.
Create the Cream Mixture: In a bowl, whisk together heavy cream, minced garlic, salt, and pepper until well combined. This mixture will infuse flavors throughout the layers.
Layer It Up!: Start layering your sliced potatoes into the baking dish. Pour some cream mixture between layers, followed by a generous handful of cheddar cheese.
Bake Until Golden Brown: Cover with aluminum foil and bake for about 45 minutes. Remove foil and bake for an additional 15-20 minutes until bubbling and golden brown on top.
Enjoy preparing this delightful potato au gratin! Your kitchen is about to fill with heavenly aromas that will have everyone eagerly waiting at the table.
