This luscious potato gratin brims with silky creaminess and gooey cheese layered between tender slices of potato. It makes an irresistible side for chilly evenings or holiday tables and always draws requests for seconds in my kitchen.
I fell in love with this gratin when I served it for a Sunday dinner and guests raved about its balanced flavor and melt-in-the-mouth texture. Since then it has become my go-to for feeding a crowd or elevating a humble weeknight meal.
Ingredients
- Potatoes: Look for starchy varieties such as Yukon Gold or Russet for the perfect creamy texture
- Heavy cream: Choose the freshest cream possible for richness
- Cheese: Gruyère or Comté are excellent for nutty flavor and meltability but use Emmental or Swiss in a pinch
- Nutmeg: Adds a subtle warmth and depth a little grated fresh goes a long way
- Salt and pepper: Always use fresh cracked to bring out the savory layers
When choosing potatoes avoid waxy types as they hold their shape too firmly and will not yield the soft luscious interior.
Step-by-Step Instructions
- Slice the Potatoes:
- Peel and thinly slice the potatoes using a sharp knife or mandoline The slices should be even and no thicker than one eighth inch for even cooking
- Season and Arrange:
- Lay out half the potato slices in a buttered baking dish overlapping slightly Sprinkle with salt and pepper then freshly grate nutmeg over the layer
- Add the Dairy and Cheese:
- Gently pour half the heavy cream over the potatoes then scatter half the grated cheese Repeat layering with the remaining ingredients finishing with more cheese on top
- Bake Until Golden and Bubbly:
- Cover with foil and bake in a preheated oven at three hundred seventy five degrees Fahrenheit for thirty five minutes then uncover and continue baking for fifteen to twenty minutes until the cheese is golden and the potatoes are very tender
- Rest Before Serving:
- Allow the gratin to sit for ten minutes before scooping this helps the layers set and makes serving much easier

The cheese crust is always the most sought after part of this dish in my family My youngest begs to pick the golden corners every single time and I admit I usually sneak a bite too
