Our Favorite Casseroles for Warm Weather

While casseroles tend to see a lot of rotation in the winter, summer has plenty of baked dishes worth celebrating. While raw summer produce can be amazing, most kinds of summer produce is perfectly at home baked into a tender cobbler or pie. Leaning on fresh herbs, lighter cheeses and simple prep, these recipes are perfect for everything from weeknight dinners to potlucks and backyard gatherings. Whether you’re looking to use up a bumper crop or need a crowd-pleasing side for the picnic, these recipes bring all the comfort of a casserole with a decidedly warm-weather feel.

Fruit crisps don’t necessarily have to be strictly desserts. Swap out the fruit for tender eggplant and you have a savory side with tons of texture. Toasted walnuts and panko breadcrumbs form the crunchy topping that pairs perfectly with the softened vegetables below.
