Slow Cooker 3-Ingredient Cheesy Potato Casserole is the ultimate comfort dish. Creamy, cheesy, and packed with flavor, it requires just three simple ingredients yet delivers a crowd-pleasing side that’s perfect for weeknight dinners, potlucks, or holiday meals. The slow cooker does all the work, softening frozen potatoes while blending cheese and soup into a luscious, creamy casserole.
One evening, I tossed frozen hash browns, cream of chicken soup, and shredded cheddar into the slow cooker, set it on LOW, and went about my evening. Hours later, the kitchen smelled divine, and the family gathered around eagerly. Topping the casserole with extra cheese at the end created a golden, melty finish that disappeared in minutes — creamy, cheesy, and utterly irresistible.
