Make your favorite comfort food dishes even easier to serve a crowd by transforming them into one-pan meals. Food Network Kitchen reimagined classics like French onion soup, shrimp and grits, and spaghetti and meatballs into transportable, make-ahead casseroles.

This rich, soup-inspired casserole makes a cheesy, ultra-comforting side dish (our tasters said it would make a great addition to a holiday spread) without the fussiness of a soup course. Make the onions ahead to save time.

Eat spaghetti and meatballs by the slice instead of the bowl. Each slab of this kid-friendly casserole has tiny meatballs and pockets of gooey cheese. Add slices of leftover cooked Italian sausage if you have it.

If tomato soup and grilled cheese is your go-to comfort food, then we have the perfect casserole for you. Using the broiler instead of the stovetop makes the work of grilling the bread and cheese easier — try this method when you're cooking sandwiches for a crowd.
