Quick Keto Chicken Alfredo with Spaghetti Squash

A printable recipe card is available at the end of the post.

Add the spaghetti squash and mix well. Continue to cook until the squash is heated through.

I’m a spaghetti lover from way back. But it took me a while to warm up to Alfredo sauce.

I mean, spaghetti sauce is supposed to be red and all tomato-y and stuff.

White pasta sauce just seemed wrong somehow…

But eventually I got over my objections and actually gave it a try. And boy was I hooked!

And the rich cheesy sauce is perfect for those on a keto or low carb diet.

The pasta?

Not so much.

Spaghetti squash to the rescue!

Spaghetti squash is a pretty cool vegetable that can be substituted for pasta in pretty much any dish.

If you’ve never tried it, I encourage you to do so. I wrote a post about how to cook spaghetti squash.

This keto chicken Alfredo recipe uses already cooked chicken and already cooked spaghetti squash. That means it’s a great candidate for a weekly meal prepping routine.

So all you have to do is actually make the sauce and put everything together. Takes about 15-20 minutes, tops.

Serve with a tossed salad and a keto friendly Ranch dressing, and you have a super easy weeknight pasta dinner that won’t knock you out of ketosis.

So let’s get started, shall we?

Keto Chicken Alfredo with Spaghetti Squash

Keto Chicken Alfredo with Spaghetti Squash

  • 2 Tbsp butter
  • 2 cloves of garlic, minced
  • 1 1/2 tsp chicken bouillon
  • 1 tsp sage
  • 1/8 tsp nutmeg
  • 1 1/2 c heavy cream
  • 4 oz cream cheese, cut into cubes
  • 1/2 c Parmesan cheese, shredded
  • 1 c chicken, cooked and cut into cubes
  • 1 c broccoli, cut in bite sized pieces
  • 2 1/2 c spaghetti squash, cooked
  • salt & pepper to taste
  • parsley for garnish

Start by melting the butter in a heavy bottomed skillet over medium heat.

After the butter is melted, you need to throw in the garlic, sage, and nutmeg. Stir that up and let it cook for a minute or two until it’s fragrant.

Now you need to pour in the heavy cream. Whisk that in well and then add the chicken bouillon and whisk it up again.
