Equipment

• Large mixing bowl
• Baking dish (9×13 inches recommended)
• Medium saucepan
• Whisk
• Measuring spoons and cups
• Aluminum foil
• Spatula

Ingredients

• 2 lbs russet or Yukon Gold potatoes, peeled and thinly sliced (about ⅛-inch thick)
• 2 cups heavy cream (or half-and-half for a lighter version)
• 2 tbsp unsalted butter
• 3 cloves garlic, minced
• 1 tsp salt
• ½ tsp black pepper
• ½ tsp ground nutmeg (optional, for warmth)
• 1 tsp fresh thyme leaves (or ½ tsp dried thyme)
• 1 ½ cups shredded Gruyère cheese (or cheddar for a sharper flavor)
• ½ cup grated Parmesan cheese
• ½ cup shredded mozzarella (for extra creaminess)
• 1 tbsp chopped parsley (for garnish, optional)

Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a baking dish with butter or non-stick spray to prevent sticking.

Step 2: Slice the Potatoes

Using a mandoline slicer or a sharp knife, thinly slice the potatoes into uniform ⅛-inch slices. Place them in a large bowl to prevent oxidation.

Step 3: Prepare the Cream Mixture

In a medium saucepan over low heat, melt the butter and add the minced garlic. Sauté for 1 minute until fragrant. Pour in the heavy cream, salt, black pepper, nutmeg (if using), and thyme. Simmer for 2-3 minutes, stirring occasionally. Remove from heat.

Step 4: Layer the Potatoes and Cheese

Arrange a layer of potato slices in the prepared baking dish, slightly overlapping them. Pour some of the cream mixture over the layer, then sprinkle with a mix of Gruyère, Parmesan, and mozzarella cheese. Repeat this process with remaining potatoes, cream, and cheese until all ingredients are used.

Step 5: Bake the Gratin

Cover the baking dish with aluminum foil and bake for 40 minutes. Then, remove the foil and bake for another 20-25 minutes until the top is golden brown and bubbly.

Step 6: Rest and Serve

Let the gratin rest for 10 minutes before serving. Garnish with chopped parsley and enjoy!

Tips for Best Results

• Use a Mandoline Slicer – This ensures uniform potato slices, which helps with even cooking.
• Choose the Right Cheese – Gruyère adds nuttiness, Parmesan provides sharpness, and mozzarella creates creaminess.
• Don’t Skip the Resting Time – Letting the gratin sit after baking allows the sauce to thicken.
• Enhance the Flavor – Add crispy bacon bits, caramelized onions, or smoked paprika for an extra layer of taste.

Pairing Suggestions

This cheesy potato gratin pairs wonderfully with:

• Roasted chicken, steak, or lamb
• Steamed or roasted vegetables
• A fresh green salad with vinaigrette
• A glass of white wine such as Chardonnay
