Jennie, my husband has high blood pressure so I don't use the commercially canned soups so many casserole recipes call for. I make my own 'cream of' soups using a recipe I found by searching for homemade versions of those soups. I can add chicken base to make cream of chicken, or saute some mushrooms to add to make cream of mushroom, etc. If you're interested in this, I will look up my recipe.
Here is a casserole we like in which I use my homemade version of soup.
Company Chicken
6 boneless, skinless chicken breasts
1 can cream of chicken or cream of mushroom soup
1 small carton of sour cream. (I use Daisy Light)
Place chicken breasts in baking dish. Top with soup and sour cream. Cover dish with foil and bake 350 ° for 1 hour. Check chicken to be sure it's cooked thoroughly. Serve over rice or noodles if desired.
