Homemade Mac n' Cheese

A favorite my mom made growing up. I just use low-fat for the sour cream and cottage cheese.

7oz. dry elbow mac
2 cups cottage cheese
1 cup sour cream
1 slightly beaten egg
80z. (2 cups) shredded cheddar (sharp is really good in this)
Paprika

Cook macaroni and rinse with cold water ~ drain well.
Combine rest of ingredients except cheddar and mix well. Fold in cheddar and mac. Pour in greased 8x8 pan. Sprinkle with paprika and a little cheese.
Bake at 325 for 45 minutes, uncovered.
