Chuck's Favorite Mac and Cheese

Here's one of my favorite recipes. I found it on Allrecipes years ago and have made it numerous times and my family never gets tired of it. Here goes: 

INGREDIENTS: 

1 (8 ounce) package elbow macaroni

1 (8 ounce) package shredded sharp cheddar cheese

1 (12 ounce) container small curd cottage cheese

1 (8 ounce) container sour cream

1/4 cup grated Parmesan cheese

 salt and pepper to taste

1 cup dry bread crumbs

1/4 cup butter, melted 

DIRECTIONS: 

Preheat oven to 350 degrees F (175 degrees C). Bring a large pot of lightly salted water to a boil, add pasta, and cook until done; drain. 

In 9x13 inch baking dish, stir together macaroni, shredded Cheddar cheese, cottage cheese, sour cream, Parmesan cheese, salt and pepper. In a small bowl, mix together bread crumbs and melted butter. Sprinkle topping over macaroni mixture. 

Bake 30 to 35 minutes, or until top is golden.
