Super creamy and full of tender chicken, french-cut green beans, crunchy almonds and french fried onions, this chicken casserole recipe is a satisfying dinner. It has minimal prep (chopping the onion!) and is on the table in no time.

To make this casserole recipe you will need the following simple ingredients: chopped cooked chicken, frozen french-cut green beans, an onion, cheddar cheese, sour cream, mayonnaise, a can of cream of chicken soup, slivered almonds and a can of french fried onions. My husband really enjoyed it, but had a suggestion for next time – add egg noodles. And I had to agree. So the next time I make this easy french onion chicken casserole recipe, I'm going to add about 2 cups of cooked egg noodles.

Serve this french onion chicken casserole for dinner with a fresh vegetable and salad. It would be delicious served over rice or pasta.
