Cheesy Chicken and Rice Green Bean Casserole combines two cozy casseroles in one! This cheesy casserole recipe is total comfort food.

We are officially ready for Halloween! Pumpkins have been carved, costumes are at the ready, and I’ve watched Hocus Pocus twice…alone…because nobody in my family will watch it with me.
Last stop: trick-or-treating! Before my little goblins tear it up though, they’ll be filling their bellies with Cheesy Chicken and Rice Green Bean Casserole.
This easy, cozy recipe is a frankenstein mash up of two of my favorite casseroles – Cheesy Chicken and Rice Casserole, and Green Bean Casserole – and it is PERFECTION in a baking dish. My husband declared it the best thing I’ve ever made!

Cheesy Chicken and Rice Green Bean Casserole
An easy homemade cheese sauce envelopes rice, chicken, mushrooms, and green beans that are folded together then baked until bubbly. The top is sprinkled with gluten free french fried onions then the whole thing is popped back into the oven until golden brown and crispy.
YES, french fried onions – not just for Thanksgiving! The flavor and crunch they add to casseroles is so fabulous!
Tips for Success
- Rice choice: This casserole calls for white rice, though you can use brown rice if you’d like. I tested with wild rice and didn’t love the texture of the final dish.
- Prep ahead: Dice the chicken and slice the mushrooms up to a few days ahead of time to save on prep time, and/or use chopped rotisserie chicken for an even quicker option.
- Leftovers: This recipe feeds an army, but leftovers heat up beautifully.
- Flour choice: I use a gluten free flour blend to thicken the cheese sauce, though if you don’t need to eat gluten free you can use all-purpose flour.
- Cheese choice: I love using sharp cheddar cheese for casseroles, as you can really taste it through the other ingredients, but you can use whatever cheese you’ve got on hand.
Ok! Who’s ready to fill their bellies and warm their souls with this crazy-cozy-casserole mash up?!

Step 1: Cook the Rice
First cook long grain white rice in chicken broth until tender. Fluff, then set aside. I always use Lundberg Farms White Jasmine Rice.
Step 2: Saute the Mushrooms
Meanwhile, add sliced mushrooms and shallots to a very large skillet over medium-high heat then, once the mushrooms release their liquid, season with homemade seasoned salt and pepper. Continue to saute until the mushrooms are golden brown then scoop them into a bowl and set aside.

Step 3: Saute the Chicken
Next, saute diced chicken breasts, seasoning with more seasoned salt and pepper, until cooked through. Scoop the chicken into the same bowl as the mushrooms then turn the heat down to medium.

Step 4: Make the Sauce
Melt butter in the skillet then whisk in gluten free flour and cook for 1 minute.

Next, slowly stream in chicken broth and milk while whisking to create a smooth sauce. Add salt, pepper, and garlic powder then cook, stirring often, until thickened and bubbly, 3-4 minutes.

Lastly, stir in shredded sharp cheddar cheese until smooth and fully melted.

Step 5: Combine and Bake
Add the cooked rice, chicken, and mushrooms, plus a can of green beans – cut or french-style – into the skillet then stir to combine.

Scoop the mixture into a large casserole dish, or two smaller ones, then bake for 15 minutes at 350 degrees.

Last step is to add the piece de resistance – Gluten Free French Fried Onions. I cannot TELL you what a delicious flavor and crunch these add to the casserole. Sprinkle on top then return the dish to the oven until the onions are golden brown and crispy – 7-9 minutes.

This is the brand of gluten free french fried onions I use. I actually started using them instead of making homemade crispy shallots in my Green Bean Casserole because they’re so tasty and convenient!

Let the casserole sit to thicken and cool for 10-15 minutes then scoop onto plates and dig in. I know you will love this EPIC, comfort food casserole mash up. Enjoy, enjoy!

Do you have calories per serving?
This looks amazing and is going straight on my meal plan. I’m going to make a dairy free cheese sauce with nutritional yeast since half my house is dairy allergic but I bet it will be just as delicious!
Delicious and perfect for a crisp fall night. Hubby’s only complaint was he wanted more color. Next time it gets served with a side salad.
Was it just me or did anyone else have a hard time pulling themselves away from the casserole picture to even make it to the recipe? I was mesmerized by it : ) adding to the grocery list now!
Made this for the first time last night. It will not be the last! So good and comforting in a Thanksgiving-y kind of way. My kids gobbled it up and didn’t even notice the mushrooms.
Thanks for posting this Kristin. So timely before Thanksgiving and we both loved it, made enough to last us through the week.
I’m so glad to hear that, Mary! Enjoy your tasty leftovers!!
Where do you find these french fried onions? I’ve tried a couple places an am unable to find this brand.
Thank you.
I get these in the HyVee Health Market. If you can’t find any, you can fry shallots as seen in this post! https://iowagirleats.com/gluten-free-green-bean-casserole/
Made this casserole last night and didn’t change a thing. So delicious!!
Woo, so glad to hear it, Geri! Thank you so much for your feedback and recipe rating!
I recoil from mushrooms(my only enemy!). What ingredient would be best to double up in its place…? Green beans? This sounds siiiiick, by the way, cheese sauce YUM
I totally get that – I HATED mushrooms for the first 30(ish) years of my life! I think cauliflower florets diced small then sauteed in butter vs extra virgin olive oil, like in this recipe: https://iowagirleats.com/creamy-sweet-corn-pasta-with-basil/ would be divine!
Could you share a link for where you buy the onion rings?
Hi Becky! I buy these at my grocery store’s (HyVee) health market section!
Can’t wait to try this one, Kristin. Yum yum!
I hope you love it, Nancy!!
What an awesome mash up! Putting that on the menu for next week. We are staying in and making Hocus Pocus milkshakes (at the request of my 13 year old) and watching scary movies. I am totally looking forward to a chill night!
Sounds like a blast!! Have fun together!!
Pinned this recipe, looks delicious! And yes, I’ll happily join a mom watch party for Hocus Pocus – my kids won’t watch with me either, willingly anyway ;)!
What is it with these kids? Don’t they know it’s the best halloween movie of our time?! ? Hope you enjoy the recipe!!
Can you sub cauliflower rice for the long grain?
Hi Susan! I’m sure you could add cauliflower crumbles to this recipe though I wouldn’t replace all the rice with it.
