13 Weeknight Casseroles with Minimal Cleanup

I know the struggle of weeknight cooking – you want something comforting and delicious, but the thought of washing multiple pots and pans makes you reach for takeout instead. That’s why I’ve fallen hard for one-pan casseroles. They combine all my favorite ingredients into a single dish, creating those magical layers of flavor while keeping cleanup simple.

From creamy mac and cheese made with cauliflower to rich shepherd’s pie loaded with vegetables, these 13 casseroles will transform your weeknight dinner rotation. Each recipe needs just one baking dish and minimal prep work. I’ve included my favorite tricks for building deep flavors without spending hours in the kitchen.

The best part about these casseroles? You can prep them ahead and pop them in the oven when you’re ready to eat. Many even taste better the next day as leftovers. I’ve made sure each recipe includes ingredients you likely have on hand or can easily find at your local grocery store. Get ready for your new favorite weeknight dinner solutions.
