Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- Russet Potatoes: These starchy potatoes are perfect for achieving that creamy texture; aim for about 3-4 medium-sized potatoes.
- Heavy Cream: Use full-fat heavy cream for a rich and luscious sauce that adds depth to your gratin.
- Garlic: Fresh garlic cloves enhance the flavor; I usually go for 2-3 cloves depending on how much kick I want.
- Gruyère Cheese: This nutty cheese melts beautifully; about 1 ½ cups shredded will give you that irresistible topping.
- Parmesan Cheese: Sprinkle some grated Parmesan on top for an extra layer of flavor and crunch; about ½ cup is ideal.
- Butter: A little butter greased on your baking dish ensures golden edges; around 2 tablespoons should do the trick.
- Salt and Pepper: Essential seasonings to taste; don’t skimp on these to elevate all the flavors!

Let’s Make it together
Prepare Your Oven and Dish: Preheat your oven to 375°F (190°C). Grease a deep baking dish with butter to prevent sticking and create delightful crispy edges.
Slice Those Potatoes: Using a sharp knife or mandoline slicer, thinly slice your russet potatoes into even rounds—aim for about 1/8 inch thick. This helps them cook evenly.
Create the Creamy Sauce: In a mixing bowl, combine heavy cream, minced garlic, salt, and pepper. Stir until well blended. This mixture will envelop those potatoes in creamy goodness.
Layer It Up!: Start layering half of your potato slices in the bottom of the baking dish. Pour half of the creamy sauce over them before sprinkling half of both cheeses on top.
Add More Layers: Repeat with another layer using the remaining potato slices followed by sauce and cheeses. Make sure everything is evenly distributed for consistent flavor throughout.
Bake Until Golden Brown: Cover with aluminum foil and bake in preheated oven for about 45 minutes. Remove foil and bake for an additional 15-20 minutes until bubbling and golden brown on top.
Once done baking, let it rest for about 10-15 minutes before serving. Trust me; this will make slicing easier!
Enjoy diving into this warm masterpiece that not only nourishes but also brings happiness into every bite!
