- 3 tablespoons all-purpose flour
- 2 cups heavy cream
- 1 teaspoon salt

Essential Kitchen Equipment
To make this recipe, you’ll need:
- A sharp knife or mandoline for slicing potatoes evenly
- A medium saucepan
- A whisk
- A 9×13-inch baking dish
- Aluminum foil
- Measuring cups and spoons
Step-by-Step Directions
- Prepare Your Oven
Preheat your oven to 375°F (190°C) and grease your baking dish with butter or cooking spray. - Make the Cheese Sauce
- In a medium saucepan, melt the butter over medium heat.
- Whisk in the flour and cook for 1 minute until smooth and bubbly.
- Gradually add the heavy cream, whisking constantly until the mixture thickens (about 5-7 minutes).
- Stir in salt, pepper, and garlic powder. Lower the heat and mix in cheddar cheese and 1 cup of Gruyère until melted and smooth.
- Assemble the Dish
- Arrange potato slices in overlapping rows at the bottom of your baking dish.
- Spread the sliced onions evenly over the potatoes.
- Pour the cheese sauce over the top, ensuring it covers everything.
- Sprinkle the remaining 1/2 cup of Gruyère over the dish.
- Bake to Perfection
- Cover the dish with aluminum foil and bake for 40 minutes.
- Remove the foil and bake for another 20-25 minutes until the top is golden and the potatoes are tender.
- Garnish and Serve
Let the dish cool for a few minutes before garnishing with fresh parsley or chives.
Tips and Tricks
- Potato Selection: Russet potatoes are ideal for their starch content, which helps thicken the dish. Yukon Gold potatoes can also work if you prefer a creamier texture.
- Cheese Variations: Feel free to experiment with other cheeses like Parmesan or Fontina for a different flavor profile.
- Shortcut Option: Use pre-shredded cheese and a mandoline slicer to save time.
How to Store and Reheat Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and warm in a 350°F (175°C) oven until heated through. You can also microwave individual portions, though the oven method preserves the dish’s texture better.
Pairing Suggestions
This dish pairs beautifully with roasted meats like prime rib, glazed ham, or roast chicken. For a vegetarian option, serve it alongside a crisp green salad or steamed vegetables. Complement your meal with a glass of Chardonnay or a light red wine like Pinot Noir.
FAQ
Q: Can I make this dish ahead of time?
Yes! Prepare the dish up to the baking step, cover, and refrigerate for up to 24 hours. Bake as directed, adding an extra 5-10 minutes if baking from cold.
Q: Can I freeze Au Gratin Potatoes?
While it’s best fresh, you can freeze leftovers. Wrap tightly in an airtight container and freeze for up to 1 month. Thaw in the refrigerator before reheating.
Q: How do I avoid curdling the cheese sauce?
Keep the heat low when adding the cheese, and stir continuously to ensure a smooth, creamy sauce. Avoid using pre-shredded cheese with added anti-caking agents, as they can affect melting.
