Recipe Ingredients
Here’s what you’ll need to make potatoes au gratin:
- Potatoes: 4 large (Yukon Gold or Russet), peeled and thinly sliced
- Heavy cream: 1 1/2 cups
- Whole milk: 1/2 cup
- Butter: 3 tablespoons
- Garlic: 2 cloves, minced
- All-purpose flour: 2 tablespoons
- Gruyère cheese: 1 cup, shredded (or use cheddar or a mix of both)

- Salt: 1 teaspoon
- Black pepper: 1/2 teaspoon
- Nutmeg: 1/4 teaspoon (optional)
- Fresh thyme: 1 tablespoon, chopped (optional, for garnish)
Instructions
Step-by-Step Guide to Making Potatoes au Gratin
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick cooking spray.
- Prepare the Potatoes: Peel and thinly slice the potatoes, about 1/8-inch thick, using a sharp knife or a mandoline slicer for even slices. Set aside.
- Make the Cream Sauce: In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Sprinkle in the flour and whisk constantly for 1-2 minutes to create a roux. Slowly pour in the heavy cream and milk, whisking continuously until the sauce is smooth and begins to thicken, about 3-4 minutes.
- Add the Cheese: Reduce the heat to low and stir in the Gruyère cheese, Parmesan cheese, salt, black pepper, and nutmeg (if using). Continue to stir until the cheese is melted and the sauce is smooth. Remove from heat.
- Layer the Potatoes: Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading it evenly. Repeat with the remaining potatoes and cheese sauce, making sure all the potatoes are covered with sauce.
- Bake the Dish: Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes. Remove the foil and bake for an additional 20-25 minutes, or until the potatoes are tender and the top is golden and bubbly.
- Serve: Let the potatoes au gratin cool for a few minutes before serving. Garnish with fresh thyme, if desired, and enjoy hot as a delicious side dish.
Tips for the Best Potatoes au Gratin
Choosing the Right Potatoes
- Yukon Gold or Russet: Yukon Gold potatoes have a buttery flavor and hold their shape well, while Russet potatoes are starchy and create a creamier texture. Both work well for this dish.
- Even Slices: Use a mandoline slicer for uniform, thin slices, which helps the potatoes cook evenly.
Layering for Maximum Flavor
- Layering Technique: Layer the potatoes evenly and cover each layer with a generous amount of cheese sauce. This ensures every bite is creamy and flavorful.
- Additional Flavors: Add a layer of sautéed onions or sprinkle some chopped fresh herbs between the layers for added flavor.
Achieving the Perfect Golden Crust
- High Heat Finish: Remove the foil for the last 20-25 minutes of baking to allow the top to get golden and crispy.
- Cheese Crust: Use a combination of Gruyère and Parmesan cheese for a flavorful and bubbly crust.
Serving Suggestions
Pairing Potatoes au Gratin with Main Dishes
- Roast Beef or Chicken: Serve alongside roast beef, chicken, or pork for a hearty meal.
- Salmon or Other Fish: Pair with baked or grilled salmon for a balanced meal with a touch of luxury.
Creative Variations for Au Gratin Potatoes
- Add Ham or Bacon: For a heartier dish, add diced ham or crumbled bacon between the layers of potatoes.
- Vegetable Mix: Include thinly sliced vegetables like zucchini or mushrooms for a veggie-packed version.
Making Potatoes au Gratin Ahead for Special Occasions
- Prepare Ahead: Assemble the dish up to 24 hours in advance and refrigerate. Allow the dish to come to room temperature before baking.
- Freezing: You can freeze the baked dish after it has cooled completely. Thaw in the refrigerator overnight and reheat in the oven at 350°F (175°C) for about 20 minutes, or until heated through.
Health Considerations
Making a Lighter Version of Potatoes au Gratin
- Reduce Cream: Substitute half of the heavy cream with whole milk or half-and-half to lighten the dish while maintaining creaminess.
- Lower-Fat Cheese: Use lower-fat cheese options like part-skim mozzarella to reduce the calorie content.
Using Different Cheeses for Variety
- Cheese Varieties: Experiment with different cheeses like cheddar, fontina, or Swiss to vary the flavor.
- Spicy Kick: Add a bit of pepper jack cheese for a spicy twist on the traditional recipe.
Frequently Asked Questions
- Can I use a different type of cheese in potatoes au gratin?
- Yes, you can use any cheese that melts well. Cheddar, fontina, or Swiss cheese are great alternatives to Gruyère. Mix and match cheeses to create your desired flavor profile.
- How do I prevent the potatoes from becoming too soft or mushy?
- Make sure to slice the potatoes evenly and bake at the correct temperature. Using starchy potatoes like Russets can help maintain texture, as they absorb the creamy sauce while still holding their shape.
- What are some additional ingredients I can add to this dish?
- You can add ingredients like caramelized onions, sautéed mushrooms, or thinly sliced ham for extra flavor. Fresh herbs like thyme or rosemary also add a fragrant touch to the dish.
