Barbara Beasy says
Can you substitute cottage cheese for the ricotta? Have you ever tried cottage cheese in this recipe?
Bowl Me Over says
Though I haven't tried cottage cheese, but it would work in this recipe. The tangy flavor would be excellent! Another thing I've done if I'm using cottage cheese is run it through the food processor and that gets rid of the curds. Not necessary, but just a tip. Happy Holidays Barbara!
Jill says
You have 20 oz can cream of chicken then underneath 2 cans do you use 2 20 or can?
Bowl Me Over says
Sorry for the confusion Jill. I've corrected the recipe card. You'll use two 10.5 ounce cans - 21 ounces total.
