Step-by-Step Instructions

1. Prepare the Potatoes

1. Preheat your oven to 375°F (190°C).
2. Wash and peel the potatoes, then slice them into ⅛-inch thick rounds using a mandoline or sharp knife.
3. Place the sliced potatoes in a bowl of cold water to prevent browning while you prepare the sauce.

2. Make the Cheese Sauce

1. In a saucepan, melt butter over medium heat.
2. Add the onions and sauté until soft and translucent, about 3 minutes.
3. Stir in the garlic and cook for another 30 seconds.
4. Whisk in the flour and cook for 1 minute, stirring continuously.
5. Gradually add the heavy cream and milk, whisking until smooth.
6. Stir in the cheddar cheese, Parmesan, salt, pepper, paprika, thyme, and mustard.
7. Cook until the cheese melts and the sauce thickens slightly, about 3-4 minutes.

4. Bake the Au Gratin Potatoes

Tips for Perfect Au Gratin Potatoes

• Use the Right Potatoes: Yukon Golds provide a creamy texture, while Russets create a fluffier consistency.
• Slice Evenly: Ensures even cooking—use a mandoline slicer for best results.
• Layer Cheese Between Slices: Helps create extra cheesy goodness in every bite.
• Let It Rest Before Serving: This prevents the sauce from being too runny.
• Make It Crispy: Broil for 2-3 minutes at the end for a golden, bubbly crust.
