Ingredients

For the Gratin:

  • 4 large russet potatoes, peeled and thinly sliced
  • 2 tablespoons unsalted butter
  • 2 cups heavy cream
  • 1 cup whole milk
  • 1 cup Gruyere cheese, shredded
  • 1 cup Parmesan cheese, grated
  • 2 cloves garlic, minced
  • 1 tablespoon fresh thyme (or 1 teaspoon dried thyme)
  • Salt and pepper, to taste
  • 1/2 teaspoon ground nutmeg (optional, for a warm, aromatic touch)

For the Topping:

  • 1/2 cup Parmesan cheese, grated
  • 1/4 cup breadcrumbs (preferably panko)
  • 1 tablespoon unsalted butter, melted
  • 1 tablespoon fresh parsley, chopped (for garnish, optional)

Instructions

1. Preheat and Prep the Dish

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray, ensuring it’s well coated to prevent sticking.

2. Prepare the Creamy Sauce

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add the minced garlic and cook for about 1 minute, until fragrant, being careful not to brown it.

Next, add the heavy cream, whole milk, and thyme to the saucepan. Stir everything together and bring it to a simmer. Season with salt, pepper, and ground nutmeg (if using). Let the mixture simmer gently for 2-3 minutes to blend the flavors, then remove from heat.

3. Layer the Potatoes

Place a layer of thinly sliced potatoes at the bottom of the prepared baking dish. Sprinkle a portion of the Gruyere and Parmesan cheese on top of the potatoes.

Repeat this process, layering the potatoes and cheeses until all the potatoes are used up. After the final layer of potatoes, pour the creamy sauce evenly over the entire dish.

4. Make the Topping

In a small bowl, mix together breadcrumbs, Parmesan cheese, and melted butter until well combined. Sprinkle this mixture generously over the top of the gratin. This will give you the crisp, golden crust that everyone loves.

5. Bake the Gratin

Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes. After that, remove the foil and continue baking for another 25-30 minutes, or until the top is golden brown and crispy, and the potatoes are tender when pierced with a fork.

6. Let It Rest

Once the gratin is done, let it rest for about 5-10 minutes before serving. This helps the sauce to thicken slightly and makes it easier to cut into neat servings.

7. Garnish and Serve

Garnish with freshly chopped parsley (optional) and serve warm. This creamy, cheesy gratin pairs wonderfully with a variety of main dishes and is guaranteed to be a hit.

Tips for the Perfect Gratin

  • Thinly Slice the Potatoes: The key to a creamy gratin is ensuring the potatoes cook evenly. A mandoline slicer works great for achieving uniform slices.
  • Use Starchy Potatoes: Russet potatoes work best for gratin, as their starchy texture helps the sauce thicken and create a smooth, creamy consistency.
  • Don’t Skip the Resting Time: Let the gratin rest for a few minutes after baking to ensure it holds together when you slice it. This will help you serve clean, neat portions.
  • Customize the Cheese: Feel free to swap out the Gruyere for another cheese like aged cheddar or fontina for a different flavor profile.
  • Make Ahead: You can assemble the gratin a day ahead, refrigerate it, and bake it when you’re ready. Just add a few extra minutes to the baking time if you’re cooking it straight from the fridge.

How to Serve Crispy Parmesan and Gruyere Potato Gratin

  • With Roasted Meat: This gratin is the perfect side dish for roasted meats like beef tenderloin, lamb, or roasted chicken.
  • Pair with a Simple Salad: The richness of the gratin balances beautifully with a light, crisp green salad with a tangy vinaigrette.
  • For Special Occasions: Serve this dish at holiday meals, family gatherings, or dinner parties—it’s sure to be a standout side.
  • As a Comforting Meal: If you’re in the mood for comfort food, serve this gratin as a main dish with a side of bread or roasted vegetables.

Ingredients

Scale
  • 3 lbs Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 1 cup heavy cream
  • 1 1/2 cups whole milk
  • 2 tablespoons unsalted butter
  • 2 garlic cloves, minced
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup grated Gruyere cheese
  • 1 cup grated Parmesan cheese
  • 1/2 cup breadcrumbs (optional, for extra crispy topping)

 

  • 1 tablespoon fresh parsley (optional, for garnish)

Instructions

  1. Preheat the Oven:
    Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.

  2. Prepare the Potato Layers:
    Peel the potatoes and slice them thinly (about 1/8-inch thick) using a sharp knife or mandolin. Set aside.

  3. Make the Creamy Sauce:
    In a saucepan over medium heat, melt the butter. Add the minced garlic and thyme, and cook for about 1 minute until fragrant. Pour in the heavy cream and milk, stirring well to combine. Season with salt and black pepper, then bring the mixture to a gentle simmer. Let it cook for 2-3 minutes, then remove from the heat.

  4. Layer the Potatoes:
    Begin by layering the sliced potatoes in the bottom of the prepared baking dish. Overlap the slices slightly to create an even layer. Repeat the process until all the potatoes are used, layering them carefully.

  5. Add the Cheese and Cream:
    Pour the creamy sauce evenly over the potatoes, ensuring that it soaks into the layers. Sprinkle the grated Gruyere and Parmesan cheese evenly over the top. For an extra crispy topping, sprinkle breadcrumbs over the cheese (optional).

  6. Bake the Gratin:
    Cover the baking dish with aluminum foil and bake for 45 minutes. After 45 minutes, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden brown and crispy, and the potatoes are tender when pierced with a fork.

  7. Serve:
    Let the gratin rest for about 10 minutes before serving. Garnish with freshly chopped parsley if desired.

Notes

  • If you prefer a creamier texture, you can increase the amount of heavy cream and reduce the milk slightly.
  • You can substitute the Gruyere cheese with a sharp cheddar for a different flavor, but Gruyere adds a nutty, smooth richness that complements the potatoes perfectly.

 

  • Feel free to experiment with herbs like rosemary or sage for added flavor.
