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!

It’s super small and cheap, which is great, and the recipes are all really easy and simple! Perfect for when you don’t have a ton of time to make something fancy, but you still want to get a healthy (and cheap!) dinner on the table in a hurry!

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 recipe looks so yummy!! I LOVE green bean casserole, but never thought to try it with chicken 🙂

    I’m your neighbor at Women With Intention today, thanks!

      1. This recipe serves 4-6 as written, but you can absolutely throw in more or less of anything to adjust. I don’t typically measure anymore. I just dump 🙂

      2. Hmm… I’ve never tried it that way before. (Sounds yummy though!)

        Since fresh green beans are harder than canned green beans, you might want to add the green beans earlier so they had time to cook through (without overcooking the chicken).

        It’d definitely be worth experimenting with!

      3. Can you put all the ingredients in the crock pot at the same time besides the onion to let it all cook at the same time?

      4. I’ve never tried it. I would worry that the green beans and mushrooms would get too mushy, since they don’t really need to “cook,” just get heated up.
