The first cold snap has a way of making a hot casserole sound much better than another quick skillet dinner. These 17 recipes lean into bubbling cheese, creamy sauces, potatoes, rice, pasta, and hearty vegetables, with enough variety to cover weeknight dinners, family tables, and a chilly weekend breakfast. Some are full meals in one dish, while others are substantial sides that can round out a roast or simple main. The result is a mix of casseroles that makes turning on the oven feel worthwhile as soon as the temperature drops.
