Slow cooker cajun chicken alfredo is a savory dish for pasta night! Let the slow cooker work it’s magic to make this perfect spicy dinner for your family.

If you love a bit of spice with your Alfredo pasta, you need to try this recipe.

Delicious Slow Cooker Cajun Chicken Alfredo that is full of flavor.

I chose Cajun style over the traditional Alfredo simply because I wanted a bit of spice.

Sometimes, Alfredo can be bland, however, this recipe is far from bland.

It is full of wonderful flavors.

Using the slow cooker for this recipe takes it from complicated to extremely easy. And I love easy recipes!

There is no need to thaw out your chicken beforehand. I placed my chicken in the slow cooker frozen.

If you do choose to thaw your chicken out, apply the Cajun seasoning by placing the chicken breasts into a large bag along with the Cajun seasoning.

Close the bag and shake to coat the chicken breasts with the Cajun Seasoning.

Description

Savory Slow Cooker Cajun Chicken Alfredo. Packed with wonderful flavors!

Scale

Ingredients

  • 4 skinless, boneless chicken breasts (if they are not frozen see post on how to prepare)
  • 4 teaspoons of Cajun Seasoning
  • 4 tablespoons of butter
  • 1 red bell pepper, chopped
  • 1 green bell pepper, chopped
  • 3 green onions, chopped
  • 2 cups of heavy cream
  • 1/2 teaspoon dried basil
  • 1/2 teaspoon lemon pepper
  • 1/2 teaspoon salt
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon ground black pepper
  • 8 ounces of Pene Noodles
  • Parmesan Cheese – Optional for topping

Instructions

  1. Place chicken breasts in the bottom of the slow cooker.
  2. Cover the chicken with the Cajun seasoning.
  3. Add the rest of the ingredients EXCEPT the Penne Noodles.
  4. Cook on high.
  5. After about 2.5 hours, check the chicken. If it is cooked, take the chicken out and cut into bite sized chunks and place back into the slow cooker.
  6. Add the Penne noodles at this time.
  7. Once the Penne noodles are fully cooked, it is time to serve!
  8. When serving, top with grated Parmesan cheese.

Notes

Important Tip: Yes, there is enough liquid in the recipe to cook the pasta. However, you will need to keep an eye on the pasta and stir it around. Once the pasta is done and the sauce is to the thickness you like, turn off the slow cooker or turn to “keep warm”. You do not want to burn the noodles.

  1. Love the Wente Wine and the recipe idea on what goes together. Can’t wait to try this combo. Thank you for the tips. Time to go shop. Thank you Devon!

    • This was way, way too salty. We couldn’t even eat it. I would advise to use no salt and less Cajun seasoning.

      • I am sorry Carol. I understand that tastes are different. Perhaps your Cajun Seasoning had more salt in it than mine to cause that. Here is the seasoning I used.

  2. Just made this pasta for dinner and it is the best pasta I have ever tasted. Better than any restaurant. It literally put a smile on my face. Thank you!

    • Is there enough liquid to cook 8oz of pasta in the crockpot?? Does broth or water need to be added? The cream and other juices doesn’t seem like enough liquid to me.

      • There is plenty of liquid in the recipe. Nothing else needs to be added. Honestly, it is really soupy until the end. Then it thickens up after the adding the noodles.

        • I made this tonight, there is plenty of liquid. I cooked egg noodles separately then added them at the end and put the lid back on to heat the entire thing through. I even added shrimp. I will say, it was too much liquid for my liking, I like my sauce thicker. Next time I will not throw the chicken in frozen. I suspect a lot of added liquid came from the chicken as it thawed while cooking. It was super good and I will for sure make it again!! Thanks for sharing this recipe.

          ★★★★★

  3. Do you place the chicken back in the pot to cook with the penne? If so, doesn’t the chicken get dry?

  4. Hi! This looks amazing and I am making it for Christmas Eve dinner. My question is, I need to double it. In doing so, do I need to use two crockpots?

    • Hi Kendra! You might be able to use one crock pot, but I would be safe and use 2. Just make sure to keep an eye on it after putting in the noodles. You don’t want to over cook them. 🙂 Enjoy!

  5. I want to make it for only two people, will it work if I cut the recipe in half? I feel like 4oz of noodles won’t be enough for 2 people, but if I cut everything else in half, except the noodles, there might not be enough liquid to cook them. Also, is it possible to cook the chicken on low?

    • Hello Alisa. I would think you would be find cutting the recipe in half. I have not done that myself but would think it would be fine. Or you can make a full batch and have leftovers. 🙂

      You would be fine cooking on low, will just take longer to cook.

    • Oh my gosh, it is even better left over! My sister made this when I went for a visit. No joke, I ate the leftovers for 3 additional days….. She did make a little extra sauce though, to wet it up a bit. Even without the extra, it was delicious!

      ★★★★★

  7. My family is 6 ppl & my sisters love the chilis version of this pasta is it possible to double the recipe to have enough for everyone?
    I just got a 7qt crockpot if that helps
    -Thanks Jessica(:

    • Hi Jessica.

      I “think” my crock pot is a 5 qt. You may be able to double it. When you start your recipe, start with a single batch of the ingredients and judge from that. Sorry, I don’t have a definite answer for you.

  9. Hello! Typically, how long do you cook the pasta for after it’s added to the crockpot?

    • I think the pasta cooked about 20 or 30 minutes after adding it to the crock pot. I kept a close eye on the pasta so I could turn the crock pot to warm when it was done.

    • I have not tried freezing it so I don’t know. If you try it, come back and let us know what you did and how it turned out. 🙂

  11. This is one amazing recipe. I made it tonight and love it! I do see how it is a little on the salty side BUT 1. My cajon seasoning is a cheap one so I will be getting the one you got next, 2. I don’t have garlic powder like I thought so I sort of used garlic salt…but it’s still amazing and I’ll for SURE be making it again especially since they boyfriend likes it also 😉 Can’t wait to make this for the family soon 🙂 🙂 🙂

  13. I made this recipe this past weekend and it was a huge success! It’s a well known fact that my first attempt at a new recipe usually does not turn out well, but this was amazing! I used thawed chicken thighs and it tasted like something I would have gotten at a restaurant! My husband loved it! I’m now looking at your other recipes! Thank you so much for sharing!!

    ★★★★★

    • Awesome LeeAnn! So glad it was a huge success!! Thanks for letting me know it did so well. Hope you find something else you like. 🙂

  14. Do you happen to know if i can cook on low for a longer amount of time while i am at work?? Was going to start before i left and finish up after i get home but that will be a good 8 hrs.

    • I have not done it for that long. You can try it and just put in the noodles and chunk your chicken when you get home. I would make sure the slow cooker is on the low setting for sure.

  16. I love this recipe! I only wish mine had a little more sauce to it so I could dip my garlic bread in it! Think I could add more cream and butter or even milk?

    ★★★★★

    • Glad you liked it Misty! You could try doing that. Also, if your noodles are done before the sauce thickens, you can do ahead and turn off the slow cooker and try that….

  17. Hi Devon, I’m really excited to try this recipe but I’m hoping you can help me with a couple of questions first. Approximately what is the total weight of chicken you use? Chicken breasts vary quite a bit, and I may use chicken thighs since that’s what I have in the freezer. Also, I can’t locate that brand of Cajun seasoning locally (usually I have good luck). What might be another brand you’d consider close in heat/salt content? I have Tony Cacheres but know some consider it too salty. Thanks for your help, I know this is going to be a huge hit. What’s not to love? Crockpot, heat, pasta, yummy sauce…wish I had some now. 🙂

    • Hi Michelle!

      On the seasoning, if you think it may be salty, omit the regular salt. If you think it is needed after it is done, you can always salt to taste.

      I think the chicken breasts were about a pound together. They were larger chicken breasts. I used Best Choice frozen chicken breasts. They are in a bag if you look at a store like price chopper or a local store (not Walmart).

      It really was good, may have to make it again real soon.

  18. The crockpot is on and we should be able to cut up the chicken in a couple hours. Can’t wait to taste it!!

  19. This is on top of my favorite dishes. My family loved it so much. Thank u so much for the receipt!! Mine came out perfect except I had lots of noddles so I had to add cream. The chicken was so tender it fell apart. The best!!!

  21. Hi
    I tried this recipe this past Sunday and it was fantastic! So good that it’s being made again tonight. Instead of cutting the chicken, I tried shredding it, and it turned out wonderfully. 13/10 in my opinion!

    ★★★★★

    • You might be able to get away with doubling. You will know for sure when you put all the ingredients in at the start. Just remember you will be adding noodles later.

  24. OHMYGOSH! Made this dish tonight!! Was a huge success. I will tell you…I am not too good in the kitchen. Rarely do my new dishes turn out. This was absolutely delicious!! I can’t wait to try your other meals!!

    ★★★★★

  25. I’ve made this serval times now and everyone in the house loves it. I use more cream than advised because I don’t like my food too spicy. I also use fresh egg pasta and it tastes amazing! So glad I found this recipe 🙂

    ★★★★★

    • Nora,
      They are a good sized serving (didn’t measure exact size when making) and sorry I don’t have a way of calculating nutritional information.

  27. I used ground garlic instead of garlic powder and added some mushrooms. The only thing I did different was seared the chicken to give a little more crisp before I placed in the Crock-Pot. The taste was on the spot..My husband and son both had 2 helpings so I had no lunch for work today. Great recipe..I will be following.

    ★★★★★

  28. can I add chopped garlic in place of garlic powder? Or along with the powder if a person really likes garlic

  30. Hey..this will be my 4th time making this but I never knew if I should add more heavy cream with a 16oz box of noodles..I always went with your recipe..just thought I’d ask this time???? Its definitely a hit!!

    • I would add more cream. Sorry, I didn’t get back to you sooner. Hope it turned out delicious again!

  31. For your recipe of 4 servings what size crockpot do you suggest? Would a 7 qrt suffice or does it have to be smaller to cool correctly?

  33. Is this spicy? And if so, should I half the Cajun seasons? Making this for my family and there are 4 kids ages 10-7-4 & 18 months old. They don’t like spicy food.

    • Hi, Cat!

      To be safe, I would cut down the Cajun seasoning. I don’t remember it being too bad, but everyone’s taste buds are different. Plus, it depends on the seasoning too. Your seasoning could be spicier than mine. So, yes, cut it in half. 🙂

  34. can you tell me an alternate Cajun seasoning that may work. I love spicy so that’s not an issue but I live in a very small town and have not had luck finding this one. Thank you

    • Hi Lyndsey! I would assume any Cajun seasoning would work. You may want to cut out the salt in the recipe. I don’t know how salty the other seasoning would be. If anything, people can add salt when they eat the pasta.

  35. Hello i am a little confused. It says of the chicken is not frozen to put it in a bag, do i just add the cajun seasoning or all the seasoning?

    • I am sorry for that. It does read a little bit confusing, I will fix that. I would just do chicken and Cajun seasoning.

  36. I made this pasta tonight for dinner and it was a huge hit, everybody loved it and we had absolutely no leftovers. I used thawed chicken so I seasoned the chicken with the Cajun seasoning and let sit for 30 minutes while I cut up the veggies. I added everything else minus the salt and cooked according to recipe. This pasta was sooo good, the flavor was wonderful. I think we will have this again this week, this meal will be in rotation in our home. Thanks for the recipe.

    ★★★★★

    • I am so glad you loved it!! I do think it may be time to make it again here too! Thanks for stopping by!

  37. I was introduced to this dish at a potluck at our school.. It has become a staple in our home!!! We love this dish!!!

    ★★★★★

  39. I’m excited to try this recipe! I’m just afraid that 8 oz of noodles will not be enough for 4 servings.

  40. It’s really one of the best dishes ever! I did everything the recipe called for, but I also added 1/3 cup of white wine and a little minced garlic to the crockpot. I also grilled my chicken on the stovetop to give it that charred flavor, but I didn’t let it fully cook; it finished cooking in the crockpot. When it was done I added a jar of alfredo sauce to make it extra creamy. It was soooooo good! I will definitely be making this again!

    ★★★★★

  41. Would everything still cook correctly if I just cooked everything in a pan? Obviously I would cook the chicken separately but I am worried that the liquid won’t be the same if it isn’t cook in a crock pot..

  43. Hi! We are excited to try this…but am wondering if it can be done in the instant pot? If so, how long?? Thx!

    • I bet it could be. I have not made it in there yet so I don’t know how long it would need to cook. Sorry.

  44. Just tried this and sauce separated and became very grainy and almost curdled. Took nearly 2 hours longer to cook fully as well. Thoughts on what went wrong?

    • Hi Jen, I am not sure what happened to the sauce. I am sorry that happened. The only thing I can think of with it taking 2 hours longer is that our crock pots cook differently. Maybe mine gets hotter than yours?

  45. This was very good. It was not too spicy or salty. I also browned my thawed chicken breast before I put them in the crockpot. Turned out delicious. Five stars!

    ★★★★★

    • I have not doubled it. You will have to watch how much your slow cooker will hold if you do double it. I would assume it may take longer to cook but not sure how much.

  47. This was AMAZING. I’ll go ahead and be honest and let you know that my boyfriend and I ate the WHOLE thing. lol He ate 3 huge plates and is currently insanely miserable but so satisfied!! 😉 I omitted the salt as advised since I was using a different cajun seasoning. I used the green thing of Tony’s which is technically “creole” seasoning. Wouldn’t change a thing! YUM.

    ★★★★★

  48. I made this last night, didn’t add Basil or Lemon Pepper – but added Shrimp and 2 cans of Tomato Sauce. So good!

    ★★★★

  49. Hi Devon,

    Quick question: what changes would you suggest to make this on the stove top instead of the crockpot? I have Celiac disease, and GF pasta does not hold up in the crockpot. It tasted delicious but there was not one intact noodle by the end of it (some were even underdone). We loved the sauce though and want to make it again, just on the stove. Suggestions?

    ★★★★★

    • Rachel, I am sorry to hear that. I have not made this dish via stove top. Could you make the noodles on the stove and stir them into the crock pot after the chicken and sauce is done??

  50. This was really tasty! I did add a couple of Laughing Cow wedges at the beginning and I only did 3 teaspoons of Tony Chachares plus extra cayenne and no salt. Next time, i think I’ll add more milk and a bit more penne towards the end. My pasta cooked perfectly on high for 25 minutes. It also reheated well with a splash of milk and some cheese. Thanks!

    ★★★★

  51. This was delicious! I personally didn’t add any of the vegetables because my family is full of picky eaters. It was a bit too salty for my liking, so next time I just won’t add salt. Also, it took forever to cook my noodles and they were still a bit under-done, so I will probably cook my noodles seperate and just add them to the sauce and chicken. Definitely put this in my recipe book!

    ★★★★★

  52. It tastes so good but it didn’t make 6 servings. It was more like 4 and I added a little more pasta than the recipe states.

    ★★★★

  53. I realize this is alfredo sauce but and ideas on cutting down some of the fat? Like maybe 2% milk, flour and little butter instead of the cream? Any ideas?

    ★★★★★

    • Ive used this recipe for years now, though i find the cream overpowers everything so i use half the cream, and chicken stock for the other half. turns out amazing, really bringing out the spices. I also add cooked broccoli when adding the pasta, and so far everyone has absolutely loved it. Put over a bed of fresh greens if you really want to give it the ol razzle dazzle.

  54. I found this recipe on Pinterest and plan to make it this weekend. I would like to include the Parmesan cheese topping. Did you use like the grated Parmesan cheese in a container or fresh Parmesan cheese that you grated yourself?

  55. Hey have you ever tried this recipe over the stove top? If so what should I do different?

    • I have not tried it on the stovetop. Sorry, I am not sure what you should do differently.

  56. Hi Devon!

    This is one of my favorite recipes, I use it often and know the ingredients by heart. However, I would love to know how to make it in the instant pot. Could you recommend how?

    Thank you in advance!
