Let’s Make it Together
Prep Your Ingredients: Start by preheating your oven to 375°F (190°C). While it warms up, peel those russet potatoes and slice them thinly—aim for about 1/8 inch thick for even cooking.
Layer Those Potatoes: Grease a baking dish with butter generously. Layer half of your sliced potatoes at the bottom, overlapping them slightly—think potato shingles! Season them with salt, pepper, and half the minced garlic.
Add Cream and Cheese: Pour half of your heavy cream over the layer of potatoes, ensuring they are well-coated. Sprinkle half of the Gruyère cheese on top—don’t be shy here!
Repeat Layers: Now repeat the process with another layer of potatoes, seasoning again with salt and pepper. Pour the remaining cream over this second layer before finishing with more Gruyère cheese and thyme.
Bake to Perfection: Cover your dish with aluminum foil and bake in your preheated oven for about 45 minutes until bubbling. Remove the foil and bake for an additional 15-20 minutes until golden brown on top.
Rest Before Serving: After baking, let your potato au gratin rest for about 10 minutes before serving. This allows everything to settle nicely—it makes serving so much easier!
Now that you’ve created this masterpiece, gather your loved ones around the table and watch their eyes light up as you serve this creamy delight! Enjoy each silky bite while sharing stories and laughter; after all, good food is meant to be enjoyed together!
