Ham and Cheesy Potatoes

So, this is just funeral potatoes with ham in it. I have another potatoe recipe, but I've never frozen it, so I don't know how it would do. But this is tried and true.

16oz frozen hashbrowns
1 cup sour cream
1/2 cup chopped onion
2 cans cream of chicken soup
2 cups shredded cheddar cheese
crushed cornflakes
2 cups cubed ham

Combine, cereal, sour cream, soup, onion, ham and 1 cup of cheese. Pour mixture into greased pan. Spread crushed cornflakes on top. Top with remaining cheese.

Cook frozen at 400 degrees for 1 1/2 hours. Not frozen cook for about 45 minutes at 350, just make sure it's heated through and potatoes are cooked.
