How to make cheesy potato casserole
- Preheat Oven – Preheat the oven to 350°F and grease a 9×13″ casserole dish with cooking spray.
- Mix Sauce – Whisk the sour cream, condensed soup, 1/4 cup of the butter, milk, garlic powder, onion powder, salt, and pepper together in a large bowl.
- Add Ingredients – Add the potatoes or frozen hash browns to the bowl, first making sure any lumps are broken up. Add the cheeses to the bowl as well and toss everything well to coat.
- Finish & Bake – Dump the mixture into the prepared casserole dish. Toss the crushed potato chips with the remaining 1/4 cup melted butter and sprinkle to coat the top of the casserole. Bake for 40-50 minutes or until it bubbles and browned.
Can I make this in advance?
As with most casseroles, this cheesy potato casserole is perfect to make ahead of time! Just assemble the casserole, leaving off the crushed chips, cover with foil and refrigerate 1-2 days. When you’re ready to bake, don’t forget to add the crushed chip topping and you’re set!
You can also freeze your casserole, reiterating *don’t add the topping*. Cover tightly with heavy duty aluminum foil (you might want to have 2 layers of foil) and freeze for about 2-3 months.
