Homemade Chicken, Mushroom and Green Bean Casserole Recipe

Homemade Chicken Mushroom & Chicken Casserole

Do you ever have those evenings when you want something healthy and delicious for dinner, but you already know you won’t have time to cook?

Maybe it’s Wednesday nights when you’re headed to church or Thursday nights when you’re busy with the church softball league?

If so, this Crock Pot Chicken, Mushroom and Green Bean Casserole recipe is absolutely perfect.

Not only is it deliciously filling, but it is also incredibly easy as well.


I’ve actually been making this recipe for several years now, ever since my oldest was a baby, and it’s always been one of my favorite chicken casserole recipes.


I got the recipe idea from Our Favorite Slow Cooker Recipes Cookbook, a cute little slow cooker cookbook my husband got me that I used all the time when we first got married.

The original recipe called for slightly fewer ingredients and didn’t call for shredding the chicken, but I like the version my husband and I eventually ended up with much better! It’s really yummy!

Anyways, I would make this chicken and green bean casserole on nights I had to work, because I could prepare it in advance, and then it would be ready for my husband when dinner rolled around.

These days, though, I usually make it on a busy weeknight when I need to have dinner on the table fast. I just throw the chicken in on my lunch break, toss the rest of the ingredients in real fast when I get home, and it’s ready by the time I’m ready to eat!


This recipe also works great as a Sunday dinner recipe too. You can get the bulk of the prep work done in the morning (or even the night before), and then it just takes about 30 minutes while you’re getting changed out of your church clothes to finish up. It’s very hands off.


No matter how many times I’ve made this recipe, my family never grows tired of it! It’s fancy enough for a holiday get-together, yet simple enough for your average weeknight meal. It has plenty of nutritious veggies in it, but it tastes way more like comfort food than health food.


This recipe has morphed a lot over the years, thanks to tweaks both my husband and I have made. Now, it’s better than ever. If you love good home cookin’ – especially crock pot green bean casserole – you’re going to love this Chicken, Mushroom and Green Bean Casserole recipe!

  1. This is just ok. the chicken, and the casserole both took way longer than the recipe said, which kind of messed up dinner and we ended up eating a bunch of other stuff first since this wasn’t ready til hours later than dinner time. I made my own onions and “cream of” soup, and added cheese as my regular green bean casserole has cheese in it.. it definitely needed way more flavoring, but maybe that was the fault of those other recipes I used for the ingredients.. I had high hopes for how easy this seemed, but I think I will not make this again.

    1. Awww, that stinks that the variation you tried didn’t work out. And I would imagine making your own onions and “cream of” soup would take forever! That’s why I make it the way I wrote out in the recipe — much faster and tastier 🙂

      1. It was your recipe that took longer, I’m aware that my making the rest by scratch was more work. The only variation to your recipe itself was the cheese which shouldn’t affect the chicken and then the casseroles cooking time.

  2. Brittany,
    When I hear homemade, I think from scratch. So this was a disappointment when I read the recipe, use can of cream of mushroom soup,and can of green beans. It would be great with homemade cream of mushroom soup and fresh green beans.

    1. Yes! The recipe just calls for the small, standard size can. Although lately I’ve been buying the bigger “family sized” can and putting a little more in (not the whole big can, but maybe 2/3 to 3/4 of it?) just to get it a little extra saucy. The recipe is completely flexible — it’s just whatever your family likes best!

    1. Can I get an oven-based version of this recipe? Title did not specify slow-cooker and I didn’t realize until after already purchasing the ingredients. 🙁

      1. On Pinterest, search: Chicken, Green bean, Stuffing Casserole…an oven recipe version ?
