This was very tasty and easy to make. I think that nest time I will double the topping ingredients since the topping was good but I felt just not enough.
I tried this recipe because I had all of the ingredients on hand. The most interesting part of this casserole is the slightly tangy taste of the mayo/sour cream mixture. I added about a tsp of minced garlic and about 3/4 cup cheddar cheese. I then topped it with some more cheddar before taking it out of the oven. Even then, I think it could have used more flavor. Could have used a greater amount of "sauce," too. It's a great start to a comfort food. Just needs a little tweaking to add your own personal tastes. I didn't rate it because of the changes I made. Thanks for sharing.
