Some nights call for dinner with more substance than a bowl of greens can offer. These 23 casseroles bring chicken, beef, shrimp, pasta, rice, potatoes, beans, tater tots, and plenty of cheese into dishes that are easy to scoop and filling enough for the main event. Several use shortcuts such as rotisserie chicken, frozen meatballs, canned beans, or prepared chili, while others can be assembled ahead. A few lean more toward side-dish territory, but the lineup stays firmly focused on hearty baked food.
Vintage Chicken Divan
Broccoli and chicken share the same creamy pan in Vintage Chicken Divan, an eight-serving casserole ready in 30 minutes. One pound of chicken cooks with broccoli, mushrooms, onion, stock, milk, cream, Dijon mustard, lemon, and cheddar before baking. Rice or egg noodles can go underneath if dinner needs even more substance. The short total time makes this a useful choice when a light meal will not do but the evening still calls for something manageable.
