These scalloped potatoes feature thinly sliced Yukon Gold or Russet potatoes layered with a rich cheese sauce made from sharp cheddar and Gruyère. The sauce is thickened with a buttery roux, infused with onion and a hint of Dijon mustard, then combined with whole milk and cream for a velvety texture. After layering the potatoes and sauce, the dish is baked covered until tender, then uncovered to develop a golden, bubbly crust. A garnish of fresh chives or parsley adds a bright, herbal note. Perfect as a comforting side for any occasion.

Keeping It Fresh

Using fresh cream and milk really makes a difference—the sauce stays rich without feeling heavy. I like to chop the onions extra fine so they melt right in, disappearing into the deliciousness.

This pairs wonderfully with roasted meats or a crisp green salad for contrast. When I serve it for vegetarians, I swap the bacon for smoked paprika, adding depth while keeping it meat-free.
