Slow Cooker Garlic Parmesan Chicken
Sometimes I enlist my husband’s help on what I should make for dinner. Yesterday he said, “I’ll give you the recipe title and you create the recipe.” In my mind I was instantly transported to a food network game show. Challenge accepted. He said the name of the dish I must create is slow cooker garlic parmesan chicken. I knew that with garlic, parmesan cheese and chicken I would definitely be able to crush my imagined competition and win the game show. Well I don’t know if I won the game show but I did win dinner last night for my family. They all loved what I came up with! It reminds me a lot of chicken alfredo but I think it’s better. More flavorful and it has spinach. I would have added mushrooms but my husband had eaten the last of them for lunch in a concoction he made up with quinoa and buffalo sauce. Maybe he was in his own game show…

What Slow Cooker Did You Use?
To make slow cooker garlic parmesan chicken I used my 6 quart oval Kitchenaid slow cooker.* I love this slow cooker (you can see me talking about it in a video here). It cooks low and evenly. I love the medium heat choice because most slow cookers that I’ve seen only have the option of cooking on low or high. If you’re going to buy just one slow cooker, this is the one that I recommend.

Description
A creamy slow cooked chicken dinner with a garlic parmesan sauce and chopped spinach. We like to eat this chicken and sauce with fettuccine noodles or with mashed potatoes.
Ingredients
- 2 Tbsp melted butter
- 1 small yellow onion, diced
- 4 large garlic cloves, minced
- 1/2 cup chicken broth
- 1/2 tsp garlic powder
- 1/4 tsp pepper
- 1/2 tsp salt
- 8 oz sliced mushrooms (optional)
- 1 1/2 lbs boneless skinless breasts sliced into 1/2 inch filets
- 1 cup evaporated milk
- 3 Tbsp flour
- 1/2 cup parmesan cheese
- 3 oz coarsely chopped spinach
- Salt and freshly ground pepper
Instructions
- Add butter, onion, garlic, broth, garlic powder, pepper and salt to the slow cooker. Stir. Nestle the mushrooms (if using) and the chicken into the crock.
- Cover and cook on low for 3-5 hours (this is the time for a 6 quart slow cooker and thawed chicken breasts cut into 1/2 inch fillets).
- Remove the lid. In a small bowl whisk together the evaporated milk and flour until it is smooth. Stir it into the slow cooker. Turn the slow cooker to high and cover for another 30 minutes, until the sauce has thickened.
- Use tongs to place chicken on a platter. Loosely cover with foil. Stir the parmesan cheese and spinach into the slow cooker. Salt and pepper to taste. Serve chicken and sauce with noodles, mashed potatoes or rice.

How long to cook if I use frozen chicken breast that aren’t cut in half?
Karen says
if they are large probably 6 hours on low
Chad says
So I I didn’t have time to use the crockpot. Cubed and cooked the chicken, and made the sauce on the stovetop and made rice. Hot rice,, chicken, and then sauce on top. Very very good and the sauce only took about ten minutes to thicken perfectly.
Karen says
Great to know you can make it on the stove! Thanks for the 5 stars.
Julie says
Hi there! I’m planning to make this for dinner tonight. I’m planning on using my big crockpot for 4 hours on low but I don’t have evaporated milk — all I have on hand is about 1/2 cup of heavy cream and some whole milk. Planning to add at the end, but how much of each should of those dairies should I add and will I still need the flour (if so, how much flour?)?? Thanks!
Karen says
I would use a half cup heavy cream and a half cup of milk. I would use the same amount of flour.
Alyssa says
This was an unmitigated disaster for me. I followed the recipe exactly, weighed my chicken, measured everything, 6oz West Bend Slow Cooker. The sauce never thickened and tasted like chicken broth with a little cheese. I have a supply of basically boiled chicken now, I guess? 😥
Bill Townsend says
Karen, I’ve been following you for a couple of years, I’ve never had a bad recipe. Thank you for what you do!
I used penne pasta, and I added a handful of Costco bacon bits and I had some country ham on hand, so I tore the scraps up and threw them in there. It was excellent. I’m thinking about adding sundried tomatoes, basil, oregano, and even some artichoke hearts next time.
Thoughts?
Karen says
Those ideas sound amazing!! Try it out!
Daniella says
Is there an instant pot version to this yummy sounding recipe?
Karen says
Yes! https://www.365daysofcrockpot.com/instant-pot-garlic-parmesan-chicken/
Karen Shaffer says
I am hoping to make this over the weekend. Are you to use fresh mushrooms and spinach or canned and frozen.
Thank you
Karen says
I use fresh for both!
Catherine says
Do you think using the jar minced garlic would be OK to use?
Karen says
Yep!
Denise Doroshuk says
Thank you for this delicious recipe! I didn’t have evaporated milk so I used 1% milk which I warmed in the microwave before adding the flour. No curdling or lumps! So easy, quick and good.
Karen says
Great to hear! Thanks for sharing your experience Denise.
rosheita shelton says
How long does it take if cooked on high?
Karen says
I’d do 2-3 hours on high.
Mike says
Tasted really good. Expected something really garlicky (which would have been fine because we love garlic), but since we made it with the optional mushrooms the added flavor that seeped out of them during cooking lead to a more balanced flavor. Reminded me of stroganoff, went very well over rice.
Karen says
I love this over rice.
Misty says
I plan on making this recipe tonight however noticed you said you were going to retest it because of all the people commenting that milk curdled. Was wondering if you did happen to retest it and what results were ? I just bought all ingredients and was going to make it tonight then started reading comments about curdling.
Karen says
Hi Misty, in the original recipe I had added the milk at the beginning. I’ve changed it so that the milk is added later and it doesn’t curdle.
Misty says
Umm I followed the recipe you have posted above put the evaporated milk in after the 3 hour mark now waiting the 30 minutes. Is that what you mean by last ? I hope so or else I am gonna have to throw this whole dinner out
Misty says
Wow sauce wasn’t curdled at all but man you better really love garlic to like this meal . Like you may scare away a vampire with your breath type garlic ! 😳
Karen says
yes that’s right 🙂
Cathy Dallas says
Hi Karen, Can you freeze this recipe?
Karen says
Yes I think it would be okay frozen.
Saide says
1/2 cup broth? This did not even cover the chicken. Is this correct?
Karen says
Yes that’s right 🙂
Rosa says
It as super good!! Will definitely make it again. Thank😊 !!!
Karen says
Great!
Christine says
How many hours on low for those that have made this?
Christine says
How many hours on low from your experience
3 to 5 is big gap
Jen says
This was delicious! My daughter even loved it (the spinach included)! Will definitely be making this again!
Karen says
Awesome Jen! Great to hear!
Deb Wilkie says
This recipe sounds delicious! I’m definitely going to try it, but I wanted to ask if you think it would be necessary to adjust the time if I use my casserole crock pot to cook it. I’ve done cubed steak with mushroom sauce in the casserole crock, and they come out sooooo tender and moist, but I’ve not tried chicken (or anything else) in it since I bought it. Thanks for any advice you can give!
Karen says
It will be a similar time, I think. It may take a little more time. But it will be close.
Gail says
Can’t you just take the chicken out of the slow cooker and cook the sauce on the stove top?
Karen says
Yes!
Lindsey says
SO delicious! Had it over spinach fettuccine. Will definitely try again.
Tanya says
Curdled for me too. I was so sad as it smelt amazing. Used Evaporated milk and was only on low for 3 hours. Any ideas as to what could of caused it? Thanks
Karen says
I am not sure Tanya! I am retesting this recipe because so many have had issues with the curdling.
Nicole says
Your milk curdled because of 2 things…you cooked it in the slow cooker …on high …and because the butter and chicken fat separated the milk solids…..i make the sauce in a pan on the stove and mix it into the noodles. I remove the chicken ..add the noodles with sauce back into the crockpot and put the chicken on the top. I only then heat the crockpot on the warm setting.
Foodlover says
Try using Heavy Whipping Cream – it works so much better! Make sure to whip it up in a bowl or large cup until its smooth, like the recipe calls for. Promise, works like a charm – This recipe is absolutely delicious – my whole family loved it!
Judy says
I really tried to like this recipe. Please tell me why my milk curdled?
Karen says
Boo! Did you use evaporated milk?
Molly says
I want to make this but husband is lactose intolerant
Karen says
Oh sad! I’m not familiar with dairy free options to recommend how you would alter the recipe. 🙁
NICOLE says
I too am lactose intolerant…i used fair,I’ve whole milk…it is lactose free
Brenda Bates says
We had this for dinner Saturday evening and it’s a keeper. I added canned mushrooms and kept everything else the same, and we also had it over fettuccine. Delicious, and looking forward to the leftovers this evening! Thanks for another keeper!
Karen says
So glad you liked it Brenda!
Brenda Bates says
Another comment – for leftovers last night, I reheated them in my Instant Pot using the “pot in pot” method, 10 minutes on “Steam” and it reheats beautifully. The fettuccine was nice and tender and not rubbery like it gets if reheated in a microwave. I use my IP to reheat leftovers as much as I use it to cook. So glad you have a great variety of IP recipes here!
Brenda Bates says
And I just realized I left my review in the slow cooker section instead of the Instant Pot/Pressure Cooker section. 🙂
Karen says
Oh well!
Karen says
COOL!!!
Amy says
Where can I find this recipe to fix in the insta pot? Thanks
Karen says
Right here: https://www.365daysofcrockpot.com/instant-pot-garlic-parmesan-chicken/
Christine says
How long on low setting 3 to 5 is big gap?
Karen says
I’d go with 4 hours.
Katy says
Any substitutes for evaporated milk? Also I love all your recipes. They help my meal plan, especially the days we work.
Karen says
You could add in half and half or heavy cream instead but only after it is done cooking. If you add fresh dairy at the beginning it will curdle.
Meghann says
My evaporated milk curdled… had to throw the whole thing out. I work long days so it was on low for 11 hours, is that just too long? Maybe fresh dairy at the end is better in my situation?
Karen says
Oh I’m so sorry that happened! I bet it was just too long and maybe your slow cooker cooks too hot? Next time add fresh dairy at the end. Half and half or cream.
Helen says
I haven’t tried this yet.. however in the past I’ve found chicken breast weird in the crockpot. Thigh is better. Anyone else agree
Tina says
So quick and easy to make, and it tasted very good!! I added the mushrooms and more spinach. I also used half & half cream instead of the evaporated milk. My sauce didn’t thicken up enough though, so I’ll use more flour next time. Thanks for the recipe!!
Karen says
Glad you liked it Tina! Thanks for taking the time to comment 🙂
