Unexpected company can turn dinner into a scramble when the fridge was not planned for extra plates. These 21 casseroles lean on chicken, beef, pasta, rice, potatoes, cheese, and pantry shortcuts to turn one baking dish or slow cooker into enough food for a group. Most serve six to ten, and many land in the 30-to-60-minute range, while a few longer recipes suit visits that stretch through the evening. The result is a lineup of scoopable, bubbling dinners that need little more than a salad, bread, or simple vegetable beside them.
