Homemade Cheesy Potato Casserole
Description
The casserole starts by peeling and dicing russet potatoes into bite-sized pieces, which are boiled until just tender. While the potatoes cook, a roux is made by sautéing diced sweet onions and garlic in melted butter, then sprinkling flour to develop a thick base. Gradually adding chicken broth and whole milk while whisking creates a creamy sauce that is seasoned with sea salt and freshly cracked black pepper.
The cooked potatoes are added to this sauce along with sour cream, shredded Colby Jack cheese, and sliced green onions, which together create a rich and flavorful mixture. This combination bakes into a casserole that is creamy, cheesy, and textured by the softened potatoes and mild onion notes.
This dish works well as a comforting side to various mains and can be prepared in advance. The use of russet potatoes offers a fluffy texture, and the Colby Jack cheese adds a mild creamy flavor without overpowering the dish.
