Ingredients

  • Potatoes: 4 large russet potatoes, thinly sliced

  • Cheddar Cheese: 2 cups, shredded
  • Parmesan Cheese: 1/2 cup, grated

  • All-Purpose Flour: 2 tablespoons
  • Salt: 1 teaspoon
  • Black Pepper: 1/2 teaspoon
  • Nutmeg (optional): A pinch
  • Fresh Parsley (optional): For garnish

Instructions

  1. Prepare the Potatoes: Preheat your oven to 375°F (190°C). Peel and thinly slice the potatoes using a mandoline or knife for uniform thickness.
  2. Make the Sauce:
    • In a medium saucepan, melt the butter over medium heat.
    • Whisk in the flour and cook for about 1 minute to create a roux.
    • Gradually pour in the heavy cream and milk while whisking continuously to avoid lumps.
    • Stir in the garlic, salt, pepper, and nutmeg (if using).
    • Cook until the sauce thickens slightly, then remove from heat and mix in 1 cup of cheddar cheese until smooth.
  3. Assemble the Dish:
    • Lightly grease a 9×13-inch baking dish.
    • Arrange half of the potato slices in an even layer.
    • Pour half of the cheese sauce over the potatoes and spread evenly.
    • Repeat with the remaining potato slices and sauce.
  4. Top and Bake:
    • Sprinkle the remaining cheddar cheese and Parmesan cheese evenly over the top.
    • Cover the dish with aluminum foil and bake for 40 minutes.
    • Remove the foil and bake for an additional 20-25 minutes, or until the top is golden and bubbly.
  5. Cool and Serve: Allow the dish to rest for 10 minutes before serving. Garnish with fresh parsley if desired.

Serving and Storage Tips

  • Serving: This dish pairs wonderfully with roasted meats, vegetables, or a fresh salad for a complete meal.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for the best texture.

FAQs

1. Can I use a different type of cheese?
Yes, feel free to use other melty cheeses like Gruyère, mozzarella, or a blend for added flavor.

2. Can I prepare this dish in advance?
Absolutely! Assemble the dish up to a day ahead, cover it tightly, and refrigerate. Bake just before serving.

3. Do I need to peel the potatoes?
Peeling is optional. Leaving the skins on adds texture and nutrients but may slightly alter the dish’s creaminess.

4. Can I freeze Au Gratin Potatoes?
While it’s best served fresh, you can freeze it. Let it cool completely, cover tightly, and freeze for up to 1 month. Reheat in the oven until warm and bubbly.

Ingredients

Scale
  • 3 pounds Yukon Gold potatoes, thinly sliced (about inch thick)
  • 1 medium onion, thinly sliced
  • 2 tablespoons unsalted butter
  • ¼ cup all-purpose flour
  • 1½ cups whole milk
  • 1 cup heavy cream
  • 1½ cups shredded sharp cheddar cheese
  • ½ cup shredded Gruyère cheese
  • ¼ cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • Fresh parsley, chopped (for garnish)

Instructions

  • Preheat Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  • Prepare Potatoes and Onions: Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Top with the sliced onions, then add the remaining potatoes on top.
  • Make the Cheese Sauce:
    • In a medium saucepan over medium heat, melt the butter.
    • Whisk in the flour to form a roux, cooking for about 1 minute until lightly golden.
    • Gradually whisk in the milk and heavy cream, stirring constantly to avoid lumps. Continue to cook until the mixture thickens, about 3-5 minutes.
    • Remove from heat and stir in the cheddar, Gruyère, and Parmesan cheeses until melted and smooth. Add the garlic powder, salt, and pepper, mixing well.
  • Assemble the Dish: Pour the cheese sauce evenly over the layered potatoes and onions, ensuring all pieces are well coated.
  • Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 60 minutes. Remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
  • Garnish and Serve: Allow the dish to rest for 10 minutes before serving. Garnish with freshly chopped parsley.

Notes

  • For uniform potato slices, consider using a mandoline slicer.
  • Yukon Gold potatoes are recommended for their buttery flavor and ability to hold their shape.
  • Feel free to experiment with different cheese combinations, such as adding Fontina or using only cheddar.
