How to Prep Thanksgiving Casseroles for a Crowd

The secret to stress-free hosting is prepping your casseroles in advance:

• Prep all ingredients the day before, storing components separately where possible.
• Assemble casseroles and refrigerate covered, or freeze if prepping further ahead.
• Bake casseroles on the day, allowing them to rest before serving so flavors meld and textures set.
• Use disposable or decorative casserole dishes for quick clean-up and beautiful presentation.

Serving Suggestions and Garnishes

Highlight your casserole spread with creative garnishes: sprinkle fresh herbs, crispy onions, crushed nuts, or colorful toppings. Serve alongside roast turkey, ham, or plant-based mains for a robust Thanksgiving feast that truly satisfies a crowd.

Nutrition and Serving Sizes

Most casseroles serve between 10 to 12 people, making it easy to multiply recipes for your guest list. Caloric content varies from lighter veggie dishes (about 120–180 calories per serving) to heartier, cheesy or potato-based casseroles (up to 350–420 calories per serving). As always, balance richer dishes with lighter sides for variety.
