- Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius and grease a nine by thirteen inch baking dish thoroughly with butter or nonstick spray to keep the casserole from sticking and make cleanup a breeze
- Mix the Ingredients:
- In a large mixing bowl combine the thawed hash browns diced ham both cheeses chopped onion melted butter cream of chicken soup sour cream garlic powder onion powder salt and pepper Stir with a big sturdy spoon making sure to break up any clumps of potato so that everything is evenly incorporated and coated in the creamy mixture
- Assemble the Casserole:
- Pour the entire mixture into your prepared baking dish Use a spatula to spread it out in an even layer pressing down slightly to compact it so you get a sturdy sliceable casserole when baked
- Add Topping Optional:
- If you choose to top your casserole now is the time Sprinkle a generous even layer of crushed cornflakes or breadcrumbs over the top for crunch making sure to cover the whole surface
- Bake:
- Cover the dish tightly with foil and bake in your preheated oven for thirty minutes This allows the casserole to steam and meld flavors Remove the foil and continue baking for ten to fifteen minutes more or until the casserole is bubbling and the top is golden brown and crisp

Storage Tips
Leftovers stay fresh in the refrigerator for up to five days Just cover the dish tightly with foil or transfer to an airtight container For longer storage this casserole freezes really well Wrap individual portions for a quick reheat breakfast or store the whole thing double wrapped for easy family meals later Simply reheat in the oven at three hundred fifty degrees Fahrenheit until warmed through for the best texture I find the crunchy topping stays crispier if you wait to add it fresh right before reheating
Ingredient Substitutions
If you do not have sour cream Greek yogurt works beautifully and adds a bit more protein Swap out the cream of chicken soup for cream of mushroom if you want a vegetarian-friendly option You can also mix in leftover turkey instead of ham or toss in bell peppers or spinach for extra veggies If cheddar and mozzarella are not your favorite feel free to explore blends like Monterey Jack or pepper jack for more kick
