Baked Stuffed Onions are a savory comfort dish where whole onions become vessels for a buttery, cheesy, breadcrumb-filled center. This recipe captures a classic American home-cooked flavor, combining sautéed onion centers, parmesan cheese, crushed croutons, and simple seasoning. Ideal as a side dish for roasts or holiday dinners, this preparation transforms the humble onion into a golden, fork-tender treat with rich, caramelized depth and a crunchy topping.
