How to Cook Mashed Potato Casserole: A Step-by-Step Guide

1. Prepare the Potatoes:
   • Peel and chop 3 pounds of russet potatoes into uniform pieces to ensure even cooking.

   • Mash the potatoes using a potato masher or beat with a hand or stand mixer for a creamier texture.
   • Fold in 1 cup of shredded cheddar cheese until well combined.
4. Prepare the Casserole Dish:
   • Spray a 2-quart baking dish with cooking spray.
