How to Make Au Gratin Potatoes

Preheat the oven to 400°F (200°C). This will ensure your au gratin potatoes bake evenly and attain that desired golden crust.
Scrub the russet potatoes thoroughly under running water. Keep the skins on for added texture and nutrients, enhancing the dish’s overall heartiness.
Slice the potatoes into even rounds, aiming for about 1/8 inch thick. This uniformity is key for even cooking, so take your time and make each slice count!
Mix the heavy cream, whole milk, flour, minced garlic, salt, and black pepper in a bowl. Whisk it until smooth, combining all flavors into a deliciously rich mixture.
Coat the bottom of your greased baking dish with softened butter. Then layer 1/3 of the sliced potatoes on top followed by 1/3 of the cream mixture. Repeat this layering process until all ingredients are used, finishing with the cream mixture.
Cover the dish with foil and bake for 30 minutes. This steaming process helps soften the potatoes and infuse them with flavor.
Uncover the dish and continue to bake for an additional 20 minutes. Look for the top to become golden brown and bubbly, a promising indicator of deliciousness to come.
Sprinkle additional cheddar cheese on top if desired, and bake for another 5 minutes until melted. This final touch adds an extra layer of cheesy goodness, making every bite irresistible!

Optional: Serve with fresh herbs like parsley on top for a pop of color and flavor.
