Preparing this dish is really not hard at all. If you prep most of the ingredients ahead of time, then assembly is a snap.

The meal is hearty and feeds a hungry family or gathering of friends.

Watch us show you how to make this amazing chicken casserole!


Searing the chicken breasts before baking the casserole is one of the keys to getting super, juicy chicken that isn’t dry.

First, season the boneless and skinless breasts generously with salt and pepper, then heat the butter in a large skillet over medium-high heat.

Sear the breasts (in batches) until the outside is nice and brown. Set aside and continue preparing the casserole. NOTE: The chicken will not be cooked through at this point, but the searing will add flavor to the casserole and helps to lock in the juiciness we want with each bite.  The breasts will finish cooking while baking in the oven.

Sautéed mushrooms provide such a deep, comforting taste and texture to this chicken and rice casserole. Have we mentioned how much we love everything mushrooms? We do!

You’ll need a total of 1 lb. of sliced mushrooms, we love using a variety of any of the following:

  • White button
  • Baby bella
  • Shiitake
  • Oyster
  • Porcini
  • Cremini

Some of our favorite dishes starring our favorite fungi include: Soppressatta, Mushroom, Black Olive PizzaGerman Schnitzel with Mushroom Gravy, Best-Ever Meatloaf with Mushroom Gravy, and Sausage-Stuffed Mushrooms!

EXPERT TIP: As the mushrooms cook down, they will be come much smaller in size. Slicing the mushrooms into large slices (or quarters), allows for an even better texture for the chicken and sage casserole. They will still be soft and delicious, but a bit more robust in the finished dish.

Sautéing the mushrooms in a large skillet, before baking the casserole, will ensure the deepest flavor.

Shallots and garlic round out the perfect taste for the mushrooms. We add a couple splashes of Worcestershire sauce for even more flavor.

And the Sherry truly compliments the mushroom so much.

Next, in a separate pan (or skillet), melt the butter and then add the flour to make a roux. Add the chicken stock and whisk in the flour.  After simmering for 3 minutes, remove from the heat and add the rice, cheese, fresh herbs, the mushroom mixture, and salt and pepper.

Now, it’s time to put the casserole together.

Use a large baking dish that will comfortably hold 5 to 6 chicken breasts. A 13×9″dish will work just fine. Grease it first with softened cooking spray, butter, or oil. Pour in the stock with the rice and mushrooms and then nestle the seared breasts evenly in the dish.

As the casserole bakes, the liquid will cook the rice perfectly.

We love adding thinly sliced almonds to the top of the casserole.  It adds a wonderful texture and taste that we think is just perfect.

Another sprinkling of fresh sage over the top after the casserole comes out of the oven adds even more flavor.

    Outstanding! I made this last night for dinner. I used only 4 chicken breasts (that’s what I had on hand). My husband went back for three helpings! We had no leftovers! I love your recipes!

    • Hi Barbie!! Woo hoo!! We LOVE that you made the chicken and sage casserole! Isn’t it so comforting and warming! And so happy the hubby liked it so much, too!! That makes us smile from ear to ear!! xoxo

  • This looks fantastic. I am going to try this. My wife cannot eat rice so I’ll make a batch with quinoa for her.

    I do have a question. What type of sherry do you use? Dry? Cream?

      • Thank you, Kris, for the response. I am making it tonight. I’ll let you know how it turns out. I’m running out on my lunch break to get some fresh sage!

  • I am following you from Japan and I wish to know if I can use Japanese rice in this dish, like the Koshihikari or the Akita Komachi varieties, that are quite standard. These varieties are usually rinsed before cooking them but I do not know if that is necessary for this dish.
    Basmati rice is also widely available in Japan, if you think that would work better.
    Unfortunately, wild rice is difficult to find where I live.
    I have only recently found your blog and I cannot wait to try some of your recipes. They look fabulous!

    I made this for dinner today. It was great! I’m a full time teacher, so it’s difficult for me to bake multi-step recipes during the week. I enjoy taking my time on Sundays though! My family loved this chicken! Even my 8 year old, who normally does not try new things commented that he loved the chicken! I also made your pineapple upside down cake for dessert. I can’t wait to cut into it later with a cup of tea! Thank you for sharing your recipes and for making me laugh with your videos!

    I was looking for something different to make with chicken and I saw this dish. It is absolutely delicious! I made it with all the ingredients listed and it is going to be a dish I will make again and again. Thank you for this wonderful recipe.

    • Hi Claudia!! Sorry for the delayed response! You don’t need to cook the rice first, just dump the rice in and save the spice packet for another use. You’re not the first person to ask that, so we’ll update the recipe to make that clarification. Thanks so much and let us know if you make it and how you like it. We really love this casserole so much! Best, Kris & Wesley

  • I made this tonight as a test for a upcoming dinner party. It is really good and smells wonderful. I also like the consistency with the flour. My question is ….how can I make this ahead of time? My concern is since the chicken is not cooked through I’m afraid to let it set and throw in the oven later. Suggestions???

    • Hi Jill! You are smart…test runs are always a good thing to do. Last thing you want are surprises on the big night. This isn’t your first time at the dinner party rodeo, I’m assuming. It depends on how far in advance you want to make the dish, up to baking it. If you follow all the steps up until you put it in the oven, you can cover and leave it in the fridge for 1 to 2 days (with 1 day giving you best results). The chicken will stay just fine in the fridge. The only thing is I would increase the baking time to an hour, as the dish will be cold once it comes out of the fridge. If you need to do make this more than a day or so before serving, it will freeze just fine. I would then let it thaw for 24 hours in the fridge, and then bake for an hour before serving. Hope this helps! Let us know how it turns out and hope your dinner party is a smashing success! Best, Kris & Wesley.

        Thank you for the quick response! I was thinking I’d make it earlier in the day but good to know about day ahead and the freezing option! I’m so glad I came across the recipe. I followed your directions to a T – It’s a keeper! I’ll serve with plain arugula salad in vinaigrette and crusty bread. Yum!! Happy Thanksgiving!!

    This would be a good dish if you did not use the flour. I can see no reason to thicken the broth with the flour and it ruined the dish for me. It tasted good except for having the rice with a thickened texture. Totally not necessary to have any thickener in this dish. The next time I make it, I definitely won’t be adding flour to the broth. The rice absorbs the broth and I can think of no reason to add flour to thicken the broth.

    • Thanks for the feedback, Dianna! We liked the consistency when we thickened a bit with the flour. But if you have better results without it, that’s great! Thanks so much!
