How to Make Potatoes Au Gratin
Preheat your oven to 375°F (190°C). Grab your trusty baking dish and give it a light spray with nonstick cooking spray. This will help ensure that your glorious creation doesn’t become a sticky mess later on.
Prepare the Potatoes: Peel and thinly slice the russet potatoes using a mandoline or sharp knife. Aim for even slices so they cook uniformly and achieve that perfect texture.
Make the Cream Mixture: In a bowl, combine heavy cream, minced garlic, salt, pepper, and fresh thyme. Whisk until well blended; this mixture should be fragrant and creamy.
Layer it Up: Begin layering your sliced potatoes in the prepared baking dish like you’re assembling potato art. Pour some of the cream mixture over each layer before adding more potatoes to ensure even distribution.
Add the Cheese: Sprinkle grated Gruyère cheese generously between layers and on top of your final potato layer. Don’t skimp here; we want gooey goodness!
Bake It Off: Cover with foil and bake in your preheated oven for about 45 minutes. Remove the foil during the last 15 minutes to allow that glorious cheese to bubble up and turn golden brown.
Now you can’t resist taking a peep at your masterpiece! Let it rest for a few minutes before serving so those flavors can mingle beautifully.
With every forkful of Potatoes Au Gratin, you’ll find yourself transported back to those cozy nights spent around the dinner table surrounded by loved ones—a truly comforting experience.
