Crock Pot Alfredo Sauce (with NO Jarred Sauce!)

Looking for a slow cooker Alfredo sauce recipe that’s made entirely from scratch? This is the one you’ve been waiting for!

Crock Pot Chicken Alfredo

A few months ago, I was tasked with the planning of our ward’s Relief Society Christmas party.

In the planning meetings with the activities committee, we decided to do something a little bit different and planned to have a pasta bar for the dinner.

We decided to have a slow cooker spaghetti sauce, along with Alfredo sauce. I figured we could easily find a slow cooker Alfredo sauce to use.

Well, I was wrong. There are loads of crock pot Alfredo sauce recipes out there…but they all require jarred alfredo sauce. And I really hate the tasted of jarred Alfredo sauce – no matter what the brand! So I was determined to find a recipe that was homemade.

Unfortunately, I had a lot of trouble doing this, so I decided to make my own.

I thought it turned out really yummy – but with this, I do have to share a few caveats. We made this sauce in two different crock pots – and it turned out differently with each one.

I used my Ninja Cooking System, and the sauce thickened up perfectly once it was simmering toward the end, and I added corn starch.

I also used my mom’s slow cooker, and it was definitely a bit more liquidy. It still tasted really yummy, and when you put it on the noodles, it wasn’t as big of a deal. However, it definitely didn’t thicken up as much as I would like.

Since I have no idea what kind of crock pot you are using, it’s hard to say how it will work with yours. If it does end up being a little more liquidy than you like, just transfer it to the stove for a few minutes so you can thicken it there. Just add a little cornstarch, bring to a simmer, and whisk until done!

But either way, here is the recipe!
