Creamy Alfredo sauce with Parmesan cheese and chicken broth simmers all day in your slow cooker.
I love Alfredo sauce, but I would definitely gain a thousand pounds if we ate it at every meal, so that’s not going to happen. But we’ll probably have it a lot more often now that we have an amazing recipe for Slow Cooker Alfredo Sauce.
To say my boys love Alfredo sauce would be a huge understatement. Huge! They certainly wouldn’t complain if I served it at every meal.
Now that I think about it, my husband and I wouldn’t mind some form of Alfredo at every meal either. But that would be a really high fat and calorie diet. Yikes!
This was so good! Just perfect for my family of four. Thank you for a great recipe. ~ Christa
Alfredo sauce isn’t super complicated to make in the first place, but being able to do it in the slow cooker is so convenient if you have a busy day planned.
My husband actually prefers it to the usual Alfredo sauce because it’s a bit lighter–there is actually more chicken broth in the recipe than cream.
What to Serve with Slow Cooker Alfredo Sauce
Balsamic Chicken
Chicken breasts marinated in balsamic vinaigrette, then baked or grilled to perfection. This easy chicken recipe is sure to become a family favorite!
Loaded House Salad
Just like a house salad from your favorite restaurant, this salad is full of delicious ingredients like tomatoes, cheese, nuts, bacon and croutons. The perfect accompaniment to any meal!
Chicken with Rosemary Butter Sauce
Sauteed chicken breasts smothered in a creamy rosemary butter sauce. Ready in 20 minutes or less!
Fresh Cucumber Tomato Salad
Crunchy cucumbers, juicy tomatoes, red onions and fresh dill are tossed in a sweet and tangy vinaigrette in this classic summer salad.
This recipe does make a lot of sauce! Which means we can have it for dinner and then my boys will happily eat the leftovers for lunch the next few days.
And if we don’t feel like straight up Alfredo sauce, I use the leftovers to make some kind of cheesy pasta bake.
Delicious! Made it the other night turned out perfect. Put cooked Italian sausage in it and added shrimp half an hour before it was done so they could be cooked properly. Excellent. Thank you. ~ Andrew
I recommend serving this rich, creamy sauce with fettuccine or linguine, but any pasta will do. And you can always add chicken, shrimp or vegetables for a more hearty meal.
This Slow Cooker Alfredo Sauce is a staple at our house because I know when I serve it, everyone will clean their plates without complaint. I hope you love it as much as we do!

WHAT PEOPLE ARE SAYING ABOUT SLOW COOKER ALFREDO SAUCE
My husband LOVES this recipe. I make it quite often and he claims it’s better than Olive Garden! I do put chicken in mine but I cook it before hand and add it into the sauce at the very end. Yumminess! ~ Caroline
I’m vegetarian, so I used a vegan “chicken” broth base, but still used the heavy cream and butter and all other ingredients the same. We cooked some “chicken” strips from Gardein brand in the air fryer and added them to each plate. Absolutely delicious. I usually tweak all our crockpot recipes, but haven’t needed to do so at all, just substituted the broth and fake chicken. ~ Diana

what is the least amount of time this could cook for? If I only have a few hours can it be ready?
Danelle
Maybe…..but there might not be enough time for it to thicken.
Heather
Thanks for the advice, Diana. My daughter is vegetarian and I was looking for creative ideas for this recipe. (she also got an air fryer for Christmas) My son loves the breaded chicken, which was served on the side. Everyone was happy!

Ronni
Can you add cream cheese and sour cream or yogurt instead of flour?
Danelle
I haven’t tried that, so I’m not sure if it would thicken the same as flour. I’d love to hear how it goes if you try it.
Katrina Nix
Can you cook the noodles in with the sauce?
Danelle
I think noodles in the slow cooker tend to get a little mushy, but you could try it.
Lori
Can I substitute vegetable broth for the chicken broth?
Danelle
Should work fine!
Caroline Stoey

Ginger
Have you doubled this recipe in the crockpot before? Would you change any directions if you did?
Danelle
I haven’t, but I wouldn’t change anything (besides doubling the amounts, of course), if I did.
Pat
Can you freeze this sauce making today
Danelle
I have not tried freezing it, so I can’t say for sure, but I think it would work. I’d love to know how it goes if you try it!
Shauna
Have you tried adding lemon?
Danelle
I haven’t but I bet it would be delicious!
Lauren
I had a question I’m putting the sauce on high and I’m cooking the sauce for 1 hour will it still work that way?
Danelle
I haven’t tried it, but I think so.
Christa
This was so good! Just perfect for my family of 4. I do have a question I’m hoping someone can help me with. Can you freeze the base sauce? Maybe defrost it, warm it and then add the parmesan cheese. I love cooking in my Crock-Pot and this is one I would love to have on hand in my freezer. Thank you for a great recipe.
Jeannie Meredith
I made this today with chicken breast, it is very tasty… The only thing I found I wasn’t happy with was it seemed to curdle slightly, have you had this happen?
Thanks for sharing your recipe…
Danelle
I haven’t, so it’s hard to say what happened. Glad you still liked it though.
Lisa
I made the first part step by step, came home right before needing to add the roux and when I stirred the food the cream and broth separated, it looked liked it has curdeled. Don’t know why.
Chris
You could use an emulsifier blender to “pull” it back together. I added a brick of cream cheese to the recipe and used my emulsifier to blend it to a nice velvety texture. I’ve found for whatever reason when I add cream cheese to a cream base it doesn’t separate and look curdled.
DKA
When I cook things in the crock that I do not want to get runny/watery I always put a clean towel between the lid and the crock pot…this absorbs the excess liquid that the crock pot makes
Erika
Finally got back around to making this again after previous runny results. Used paper towels and man oh man! Did the trick just perfectly!! Thanks!
Andrew
Delicious, made it the other night turned out perfect. Cooked Italian sausage in it and added shrimp half an hour before it was done so they could be cooked properly. Excellent. Thank You
Danelle
That sounds amazing! Can’t wait to try it!
Nicole
Can I add checked breast to this and let it cook in the sauce???
Danelle
I haven’t tried that but I think it would work.
erika
I’ve made this three times now and cannot seem to understand why it is so runny. Is it because the slow cooker creates so much additional liquid? The flavor is excellent and it’s perfect for making a large amount with minimal effort. Any suggestions on liquid reduction without compromising the flavor?
Danelle
Hmmm? I’ve never had an issue with thickness. Maybe it’s just a preference of how thick we like our sauce? I would just reduce the amount of broth you start with, or make more of the butter/flour roux, and possibly cook it a bit longer after you’ve added the thickener.
