Baked Carrot Casserole with Buttery Breadcrumb Topping

Carrot Casserole
Carrot casserole is a classic mid-century American side dish that blends tender vegetables with creamy, tangy elements and a crisp topping. Recipes like this became popular as home cooks embraced convenient pantry ingredients such as mayonnaise and packaged breadcrumbs to create comforting, crowd-friendly dishes. The addition of horseradish gives this version a subtle kick, balancing the natural sweetness of carrots. Often served at potlucks or holiday dinners, this casserole stands out for its simple preparation and satisfying texture contrast, soft, savory vegetables beneath a golden, buttery crust.
