The Ultimate Creamy, Crispy Side Dish Everyone Craves

If there is one side dish guaranteed to steal attention from the main course, it’s this Cheesy Hasselback Potato Gratin. Combining the dramatic presentation of hasselback potatoes with the luxurious creaminess of a classic gratin, this dish delivers the best of both worlds—crispy edges, tender centers, and layers of melted cheese in every slice.

Each potato is carefully sliced to create deep pockets that soak up garlic-infused cream and cheese as they bake. The result is a show-stopping dish that looks elegant enough for holidays yet comforting enough for weeknight dinners.

This is not just a side dish—it’s a centerpiece.

Why This Potato Gratin Is So Irresistible

Traditional gratin is rich and creamy, while hasselback potatoes are known for crisp texture. Bringing them together creates contrast and depth in every bite.
