Busy nights are easier when part of dinner is already handled before the clock starts working against you. These 21 casserole recipes include dishes you can assemble ahead, stage in parts, or prep through the chopping, browning, boiling, and mixing steps before the evening rush. The lineup covers chicken, beef, pasta, potatoes, vegetables, tater tots, and a breakfast bake, with options for the oven and slow cooker. That gives you several ways to move work earlier in the day and leave less to do when everyone is hungry.

A creamy pasta center under buttery cracker crumbs makes Million Dollar Casserole easy to portion once the evening gets hectic.

Cook the pasta and shred the chicken earlier, then keep those components chilled until assembly. That leaves mostly mixing, topping, and baking for the final stretch before dinner.
