When a long week is coming, deciding what to cook after work can be one more chore. These 13 casseroles range from beefy skillet and pasta bakes to chicken dishes, shrimp and grits, and make-ahead sides. Some can be assembled the night before or frozen unbaked, while others use cooked leftovers or reheat well, giving you options for dinner and side dishes without starting from scratch each evening.
Skillet Stroganoff Pie
After a long day, a skillet dinner that reheats well can save the next evening. Skillet Stroganoff Pie takes 25 minutes and serves six, layering ground beef, mushrooms, Dijon, sour cream, and peas beneath mashed potatoes. The filling and potato topping cook in one oven-safe skillet before the top gets broiled until golden. Its make-ahead option lets you prepare it the night before, then warm it through when dinner needs to be simple.
