We love easy chicken casserole recipes like Chicken Tetrazzini and One-Pot Chicken and Rice. This Chicken and Mushroom Casserole does not disappoint!

Why we love this Chicken Bake

Crowd-Pleaser! Galina (my sister’s mama-in-law) is an amazing cook and this is her chicken and mushroom casserole. It is always a hit at parties and church potlucks. We make this often.

The chicken is incredibly tender – you will savor every morsel. I’ve seen sorta-somewhat similar recipes online referred to as Chicken Gloria, but I love that this one is made from scratch. It uses simple, non-canned ingredients (no cream of chicken soup needed).

Reheats Well – This chicken and mushroom casserole also re-heats really well (if you are lucky enough to have leftovers). You will likely add this recipe to your list of favorites.

Ingredients for Chicken Casserole

The ingredients for this recipe are surprisingly simple but they just work (see full printable ingredient list below):

  • Chicken breast (or chicken tenders)
  • Chicken broth
  • Half and half*
  • All-purpose flour (or use a GF substitute)
  • Mushrooms
  • Onion – it disappears into the sauce
  • Garlic – don’t skip it
  • Lemon juice – fresh is best

*What is half and half? Half and half is basically light cream. If you aren’t able to find “half and half” at your grocery store, you can substitute with equal parts of milk and heavy cream.

Can I Substitute the Mushrooms?

You can replace white mushrooms with portabello mushrooms. If you don’t like mushrooms, you can substitute with different vegetables, just pick sturdy veggies (avoid zucchini which turns mushy). Here are some great options to replace mushrooms:

  • Frozen peas
  • Asparagus
  • Caramelized onions
  • Artichoke hearts (well-drained)

How to Make Chicken Casserole

1. Sautee Chicken: Season chicken with salt and pepper and dredge in flour. Heat 3 Tbsp oil in a large skillet over medium/high heat. Once the oil is hot, add chicken and saute until golden, and transfer to a 13×9 casserole baking dish.

Pro Tip: Work in batches if needed so you don’t crowd your pan. Don’t worry about cooking the chicken through; it still needs to go in the oven

2. Sautee Mushrooms: Add 3 Tbsp oil along and saute mushrooms and onions until soft and golden. Add garlic and saute another 1-2 min. Spread mixture over the chicken.

3. Make the Sauce: In a medium saucepan (or in the same pan you’ve been using), melt 3 Tbsp butter. Whisk in 3 Tbsp flour until lightly golden (1-2 min). Add 1 1/2 cups chicken broth, 1 Tbsp lemon juice, 1/4 tsp pepper, and whisk until smooth. Add 1 cup half & half and bring to a simmer. Season with salt and pepper to taste.

4. Combine and Bake: Pour sauce over the chicken casserole. Cover with foil and bake chicken and mushroom casserole at 350˚F for 45 minutes. Garnish with parsley if desired.

This chicken bakes in gravy so it is great served over Creamy Mashed Potatoes or Egg noodles (the same way we serve Beef Stroganoff). It’s also great paired with these fresh sides:

Common Questions

Can I substitute the chicken breast?

You can use trimmed chicken thighs or chicken tenders instead. If using chicken tenders, you don’t need to slice them.

Can I Make this ahead?

Make and combine the chicken and mushrooms and refrigerate. The next day, make the sauce, assemble, and bake as directed.

Does chicken casserole reheat well?

Yes, you can reheat a pre-baked and chilled chicken casserole in the oven: cover with foil and bake at 325˚f for about 20 minutes or just until hot, or reheat on the stovetop over low heat just until hot, stirring occasionally.

Can I freeze chicken casserole?

Yes! You can freeze leftover chicken casserole. One of my readers shared her method: “It works! I took the pan out of the freezer, left it in the fridge most of the day, and reheated it in a 350* oven for about 40 minutes.”

Cooking in a crock pot or slow cooker?

One of our readers reported great results using a multi-cooker/ slow cooker: brown the chicken in the bottom of the slow cooker using the sautee function and remove. Sautée onions and mushrooms then return chicken to the pan. Combine sauce ingredients in a pan on the stove, pour it over the chicken, and slow-cook on low for five hours.

    I have made this recipe a few times and it is amazing! I am planning to make it again for a family get together, and was wondering if I could use your separate mushroom and carrot gravy instead of the gravy in this recipe? I’m not sure if it would be too thick to substitute. Also I’m assuming this is fine to make the day before and refrigerate before baking?

    Hi I want to cook this recipe. Is there anyway I can cook with chicken tenderloin instead? Would the cooking time or anything else need to be adjusted? Thanks in advance I love your recipes.

      Hi Paula, I would use the same amount by weight and it’s even easier since you don’t have to cut them. Follow the instructions as usual.

    Made this last night, it was wonderful! I added some Italian bread crumbs to the flour and dipped the chicken in egg first. I will definitely make this again! Also have made your lemon blueberry cake several times – wow! I’m a fan. Sue from Boise

    Would carrots work instead of mushrooms? And would this work making a big batch in a roasting oven?

      Hi Debbie, hmmm… I haven’t tried capers here so I can’t say for sure. I searched the comments and one of my readers said they added 2 Tbsp capers at the end. They didn’t really say how they liked it though, it was more of a general comment.

    This looks excellent as is but I’m tempted to put in about 1/4 to 1/2 cup of Marsala wine in the sauce (before adding broth and half n half). Not sure whether to eliminate the lemon if I do that. What do you think, Natasha?

      Hi Anna, I haven’t tried that so I can’t advise. Here is what one of our readers wrote, I hope it helps “Made this the other night, actually, a double recipe because it looked soooo good…. I wasn’t disappointed. Because we wanted it served over pasta, (No Yolks Egg Noodles worked beautifully), I made it a little saucier by doubling, (or would it be quadrupling by now), the liquids. Also, to lighten it up, I substituted the half and half with milk and plain Greek yogurt. Came out so rich you’d never miss it! My husband has eaten it 4 times in two days! Great recipe.”

        Hi Jen, I have not tested that with leeks but here is what one of our readers, Susan, wrote: ” Hi Natasha! This was a huge hit with the husband tonight! My first time making it, and this will be a staple for us! I added leeks in with the mushrooms ( I saw your comment about the artichokes, and leeks came to mind, but I will try artichokes too). I will say that might sauce wasn’t nice and brown like yours, more white….I thought I cooked my roux pretty well. But it was delicious!! Served it over egg noodles!” I hope that helps.

    This casserole was easy to prepare and was really good! My husband approved:)
    I left the chicken breasts whole and sliced them in half lengthwise (I perfer to have 1 whole piece of meat per person when serving). Also substituted frozen green beans for mushrooms. Otherwise followed the recipe.
    Thanks Natasha for the great recipes! When I’m out of ideas and have no clue what to cook for supper, I come here to find ideas:)
