I hope everyone had a wonderful Thanksgiving. Raise your hand if you’re tired of turkey and ham already! 
This casserole is so cheesy, creamy and chock full of chicken, broccoli and mushrooms. And did I mention how awesome it smells while it’s baking?
It was soooo nice not to have a ton of dirty dishes (especially after all the ones from Thanksgiving) with this one-dish casserole. I cooked so much food I still don’t know how I pulled it off!
I spent most of the day Friday cleaning, then put up the Christmas tree on Saturday. It was a fun and busy weekend to say the least. Baby is such a good poser, isn’t she?!

June 6, 2017 at 8:27 amHi Penny, I’ve never used canned chicken in this recipe so I can’t say for certain how it will turn out.

February 23, 2018 at 4:42 amThank you for this. I just found you after searching Google for this recipe and so glad I found it! This is a feel good classic but this was super yummy. I paired it with Jasmine rice because my husband and daughter love it and it was great all around. I will be saving this for use in the future!

March 2, 2018 at 7:13 pmI am hoping to make this tomorrow, it sounds wonderful. My only issue is I have a package of 6 boneless, skinless chicken thighs. I don’t buy precooked chicken. I first thought of a chicken divan with the broccoli and mushrooms were extras. I ended up with the chicken in my cart, 8 Oz package of criminI mushrooms, 2 broccoli crowns, 1 block of cream cheese, 8 Oz of sour cream, a bag of shredded sharp cheddar and a bottle of Reisling. Oh yes, onions and and head of garlic. PLEASE, how can I put this together to make magic?

March 3, 2018 at 9:42 amHey Kim, this recipe is much different than the ingredients you are speaking of. I have never made a recipe with all of the ingredients you mentioned so I can’t say. The combination sounds delicious, though! 🙂

May 8, 2018 at 12:18 amCan I omit the eggs? Is that just to bind it all together?
Amy @ The Blond Cook says
May 8, 2018 at 3:45 pmHi Natalie, Yes it’s for binding. I haven’t made this without eggs so I can’t say for sure how it would turn out. Please let me know if you try! 🙂

Amy @ The Blond Cook says
September 19, 2018 at 8:45 amHi Noreen, I can’t say for sure because I’ve never made this recipe with pasta. Sorry for the delay in responding, we’re recovering from Hurricane Florence. If you tried it with pasta let me know how it turned out! 🙂
