One Pan Chicken Casserole
One pan meals are the absolute best because you have easy clean-up! Using a cast iron skillet will also, in my opinion, yield the tastiest results.
A cast iron skillet sears the chicken so well and browns the mushrooms perfectly. Then those little crispy bits made when searing the chicken will be scraped up nicely with the chicken stock to deglaze the pan.
You can use cast iron skillets for desserts too, like my Chocolate Chip Skillet Cookie Pie!
How to Make Keto Chicken Mushroom
Ingredients
You need very simple ingredients for this easy one pan chicken mushroom meal.
Chicken tenderloin or chicken breasts (you could also use skinless chicken thighs if you prefer)
Any type of mushrooms- we used Baby Bella mushrooms, white or cremini, but shiitake mushrooms would also be a great option.
Butter and olive oil or avocado oil
Fresh garlic
Fresh parsley
Fresh thyme
Salt & black pepper
Heavy whipping cream or also known as double cream or heavy cream. You could also use Half & Half or light cream, but the sauce might not thicken as well so be sure to add in some xanthan gum to thicken, just about a teaspoon.
Chicken stock or chicken broth- we used organic chicken bone broth.
Sour cream or full-fat yogurt or even a dairy free yogurt will work too.
Directions
Heat half of the butter and half of the olive oil in a heavy skillet or frying pan over medium-high heat.
Season the chicken tenders and then sear in batches until browned on all sides.
Remove from skillet and set aside.Add the rest of the butter and oil to the skillet and saute the mushrooms until they are browned and crispy.
Add the garlic, herbs and chicken stock and deglaze the pan, scraping all of the good stuff from the bottom of the pan.
Add the cream and sour cream and simmer until sauce starts to thicken. Do not boil, as cream could split.
Return the tenderloins to the pan and toss through the sauce. Cook for five more minutes or until internal temperature of the chicken is 165 degrees F.
Add some fresh chopped parsley and grated Parmesan cheese to serve, if desired.
Can I make this Low-Carb Chicken recipe dairy free?
Yes you can make the creamy sauce dairy free. The only change needed is to replace the heavy cream with coconut milk and replace the sour cream with a dairy free sour cream.
What to Serve with Chicken Mushroom Casserole
You could serve this healthy meal with many different vegetables on the side. I’m partial to a simple salad, but here are some other quick and easy side dishes you might like:

How to store Keto Chicken Mushroom Casserole
Store, covered in an airtight container, in the refrigerator for up to 5 days. You can also freeze this after it’s been cooked and cooled completely. I’d suggest freezing in individual portions so you can thaw your serving the night before for an easy lunch meal the next day.

How many serving can this recipe make? I wanna know so that i can create a meal that fits my macro.
Thanks
Right under the title of the recipe it shows 4 servings.
Excellent recipe and it is very useful for me. Thank you so much for sharing your thoughts.
Delicious! My husband even approved. I will make for company soon.
Wow! This recipe was absolutely delicious! My 18 year old son saw me cooking dinner and was disappointed when he saw me cooking the mushrooms. Guess what?! He loved it!!! This is a winner in our house. The only change I made was I added Kale to the sauce because I thought people in the comments mentioned it. I was wrong, the kale was for another recipe. LOL. But it was so good, I would add it again. This also was super easy to make because you can get everything else ready while cooking the tenders and mushrooms. It looked beautiful on the plate too. Thank you for such a great recipe!!!
That looks delicious!
Getting ready to fix this tonight but also watching calories. Can we sub unsweetened almond milk for the cream in this and other recipes? Will it thinken with using the X gum? Just curious. Thanks
It will be very thin, not creamy but you can try it.
Wow! My husband and I have recently gone Keto, and I came across this recipe. It was one of the most delicious dinners I’ve ever made. We both loved it, and loved it even more that there were only 4 carbs. Absolutely amazing, wouldn’t change a thing, thank you so much for sharing!
its a great dish.. and my fiance liked it.. thanks for sharing this amazing dish..
This was freakin’ delicious!! YUMMMMMMMM
I see the nutrition information but it doesn’t specify how much is in a serving? Do you post elsewhere on this page and I’m just not seeing it? 5 grams of carbs is a lot if it’s only 1 serving of a small tenderloin then that won’t work! I noticed this throughout a lot of your recipes. Please specify the amount if you don’t mind.
Right under the title of every recipe, above ingredients it shows servings, which for this recipe is 4 so 1 pound of chicken is 16 ounces so that means divided by 4 you have a 4 ounce serving.
Thanks for this amazing recipe. I made this recipe for my sister on her birthday.
And the good thing is she liked it.. This is my third time after my college I cooked.
Thanks a lot for this delicious and simple recipe. You have written this recipe in
a very brief way which helped me to make it perfectly. Thanks! and keep it up…
This was amazing! Used some dried up ingredients from my spice rack, no cream cheese and it still came out delicious can’t imagine how much better it is will all the ingredients! Thank you for posting!
I just started Keto and following your recipes. This was the first one I tried making and it came out perfect. I am happy to find other uses for chicken that is healthy without just baking it and having dry meat! I paired it with Zucchini and it was delish! Thank you.
This sounds delicious
This is such an awesome recipe. My husband and I LOVE it
This chicken dish was so good my husband and I couldn’t believe it was a Keto diet recipe. We loved it! It would probably be good with chunks of beef and using a beef broth. I roasted broccoli and we had a feast!
Thank you, I gotta get more of your recipes to get us going on this keto diet.
New to Keto & lately hubby is having a hard time eating chicken no matter how it’s prepared he says it too dry…. I made this tonight, I bought tenderloins on sale & they were in freezer. I served cauliflower-rice & steamed broccoli with butter on it for sides. Ohmygoodness this was super delish! We made it almost exactly as written except I only had dry thyme…. the yummy sauce poured over chicken & the “ rice” was just really good! Thanks for sharing!
I am told that you should always brine chicken for at least an hour to lock in the juiciness. I would suggest a tablespoon of salt to a pint of water.
Mine taste like sour cream any tips to have it not taste to much like that
Made this tonight and it was delicious! Will be making it alot. Thank you!
I love this recipe! Simple, delicious real foods are the best. Reminds me of Stroganoff – only better because all the flavor and no guilt. Thanks for having and sharing your passion of cooking. I love your ‘why’ – it is so motivating to me. I have a passion to find foods that satisfy the tastebuds but are also good for you as well. Sorry for rambling on. Thanks again for the amazing one pan recipe!
I love this chicken! This is the first keto receipe that I made and it was fantastic! I will.definitely make it again! Thank You!
Where is the add to favorites link on recipes?
My ‘sauce’ isn’t thickening. Any suggestions?
Longer time to thicken might be needed, you could also sprinkle in a 1/4 teaspoon of xanthan gum.
I make this often. i have started putting broccoli in it. I add the broccoli the same time as the mushrooms so im sure you could just omitt the mushrooms and it would taste just fine. I also add parmesan right at the end. Delish!
What sides would you pair with this
Mashed cauliflower would be perfect!
What is a serving?
HI Darlene,
The 1 pound of chicken is 16 ounces so divided by 4 people that would be 4 ounces each.
I made this for dinner last night and my family loved it. It was delicious! I’m looking forward to trying out more of your recipes. 🙂
My husband WILL NOT eat mushrooms. Any ideas what to use as a substitution? Could you use capers?
I think you could swap it with radishes, brussels, or even broccoli.
Hi Brenda,
I would love to make your Creamy Chicken and Mushroom Cassarole. I can’t have the cream or sour cream so I was wondering if you have any suggestions for substituting those 2 ingredients. Thanks for your help.
Cheryl
I think coconut cream would work for the heavy cream, but for the sour cream maybe a dairy free yogurt.
OMG this was delicious! I was sceptical about the need for tenderloins due to the cost but I’m so glad I did. These were so yummy! Only variation is that I used dried Thyme.
Brenda can you please keep recipes to one page when we print them? Our moms and grandmothers did it on tiny index cards so a whole sheet of paper should be plenty . I won’t print them if it’s going on two pages because I can’t see filling my whole recipe book up with two page recipes.
Cynthia really? Someone gives you a free recipe and you want it on one page? You do realize you can condense it yourself into one page. No reason to be ungrateful imo.
LOL I was just thinking the same thing, how about being grateful and accepting the free gift she just shared.
?
Are you serious Cynthia? There are several things you could try as a solution to your dilemma. You could write the recipe out yourself on a tiny little index card like your grandmother did. Or you could print on the front AND back of the paper. Or, my personal favorite is, you could simply print only one page of the recipe and see how it turns out without the rest! Seriously, your comment is one of the most self-absorbed, ungrateful things I have ever read.
I can’t even believe she write that…OMGoodness 😦 this woman is very ungrateful 🤦🏻♀️
I don’t see anyone making you print them. You can handwrite them on index cards or whatever you want
Good grief! I use the custom margins on my computer and widen the left and right, and add more spaces to the top and bottom. If the ingredients are a long list, I highlight them and make them into two columns. There are so many ways to take a recipe from two to one page because I do it all the time!
