The final backyard dinner of the season is easier when the main dish can be carried outside in one pan instead of cooked in batches at the grill. These 21 casseroles cover beef, chicken, turkey, tuna, shrimp, pasta, rice, enchiladas, and slow-cooked options, with most feeding six or more people. Several bring cookout-friendly flavors such as baked beans, sloppy joe sauce, pizza toppings, and Tex-Mex seasonings, while others lean into hearty pasta and creamy bakes. That range gives the table a clear centerpiece without making the host stay indoors all evening.
