How to Make Au Gratin Potatoes
Step 1: Prepare the Potatoes
Start by washing and peeling your Russet potatoes, then slice them evenly about 1/8 inch thick using a mandoline or sharp knife to ensure they cook evenly and soak up all the flavor.
Step 2: Make the Cheese Sauce
In a saucepan, melt butter over medium heat, then sauté minced garlic until fragrant. Whisk in flour and cook for a minute or two to form a roux. Slowly add the heavy cream while whisking continuously to avoid lumps. Once silky and thickened, stir in shredded sharp cheddar cheese until melted and smooth. Season with salt, pepper, and fresh thyme if using.
Step 3: Layer the Potatoes and Sauce
Grease a baking dish and arrange a single layer of potato slices. Pour a ladle of cheese sauce over the layer, then repeat the layering process until all the potatoes and sauce are used, finishing with a generous sprinkle of Parmesan cheese on top.
Step 4: Bake to Perfection
Cover the dish with foil and bake in a preheated oven at 350°F (175°C) for about 45 minutes. Then, remove the foil and bake for an additional 20 minutes or until the top is golden and crispy and the potatoes are tender when pierced with a fork.
Pro Tips for Making Au Gratin Potatoes
- Even Slices Matter: Uniform potato slices ensure consistent cooking and a perfect creamy texture.
- Don’t Skip the Roux: Thickening the sauce before baking prevents watery gratin and enhances creaminess.
- Rest Before Serving: Let the dish cool slightly after baking so the sauce sets for cleaner slices.
- Choose the Right Potatoes: Russet potatoes work best for that ideal creamy yet firm bite.
- Cover During Baking: Keeps the moisture in, preventing the potatoes from drying out.

Freezing

FAQs
What type of potatoes are best for Au Gratin Potatoes?
Russet potatoes are ideal because their starchy texture absorbs the creamy sauce perfectly and hold their shape well during baking.
Can I make Au Gratin Potatoes ahead of time?
Absolutely! You can assemble the dish, cover it, and refrigerate for up to a day before baking. This makes it great for busy days or entertaining.
What’s the difference between Au Gratin Potatoes and scalloped potatoes?
Au Gratin Potatoes typically include cheese in the sauce and on top, whereas scalloped potatoes traditionally use a cream-based sauce without cheese.
How do I get a crispy top without overcooking the potatoes?
Bake covered until the potatoes are tender, then uncover for the last 20 minutes to brown and crisp the top without drying out the interior.
Can I use low-fat milk or cream instead of heavy cream?
While possible, the creaminess and richness may be reduced; for best results, use heavy cream or a combination of milk and a bit of butter to mimic the texture.
