Keto Cheese Sauce

This keto cheese sauce comes together in minutes with ingredients you probably already have on hand! It’s low carb, keto friendly, and perfect for topping your steamed veggies!

Cheese sauce covering broccoli.

I am a broccoli fanatic.

Weird to admit, but it’s true. It’s just my favorite veggies and I will happily eat it steamed with just a little sprinkle of salt or raw, dunked in my homemade ranch dressing.

We usually just eat this keto cheese sauce drizzled (heavily) over steamed broccoli, but it’s also good on our air fryer frozen broccoli or as a dip for our cauliflower breadsticks.

I mean, let’s be real…cheese really does make everything better and this smooth and creamy cheese sauce is the way to go. 🙂

It’s good on cauliflower too!

Ingredient Notes:

Cream – You’ll need heavy whipping cream. I’m not sure if this would work with half and half or light cream.

Cheese – We use a mix of cream cheese, cheddar, and Gruyere. I like the flavor that Gruyere adds, but it’s admittedly a little pricy so you can sub in any cheese you like or just use extra cheddar.

Seasoning – You’re also going to add just a little bit of ground mustard and black pepper to this keto cheese sauce. This will add a little flavor and help balance it all out.

Why We Love This Recipe:
  • It’s super easy!
  • You can customize it to use pretty much whatever variety of cheese you want.
  • It’ll improve just about anything you pour it over!

How To:

  • Cream – First, you’ll want to heat your cream over medium heat. We don’t want to boil the cream, but just get it good and hot and then stir in the cream cheese. Sprinkle in some mustard powder and stir until everything is combined. This easy cheese sauce recipe is so simple!

ingredients for homemade cheese sauce

  • Cheese – Turn the heat off and add your freshly grated cheddar and Gruyere. The residual heat should do the work of melting it, but you can help it along by stirring until is has fully melted and is smooth and creamy!

That’s it! The keto cheese sauce will start to thicken as it cools, so serve warm. I can’t wait to hear what you plan to put this easy homemade cheese sauce on! I’ve been meaning to pour it over a bunless burger – doesn’t that sound so good and so decadent?

Helpful Tip!

If the keto cheese sauce is too thick or too thin you can either add additional cheese to thicken it or additional cream to make it thinner.


How to store cheese sauce?

This cheese sauce is best stored in a sealed mason jar or an airtight container in the refrigerator. It should last up to 4 to 5 days. To reheat, just add a splash more of cream and microwave in short bursts, stirring as needed.

  1. So many promotional popups on your website, its annoying when trying to read your content.

    1. Karly Campbell

      Hi Luke! There are definitely ads on the site, but the only pop up should be one offering a free email series. Are you receiving more popups than that?

      1. Yes, he’s right. A lot of popups everywhere on the website I can’t even concentrate

    2. I wanted to say that yes, they are correct with the popups. Videos ads are popping up all over my screen on mobile. Very annoying. I have popups disabled. You can’t scroll but a few seconds before it pops up again.

      1. Karly Campbell

        Hi Laurie! Are you still getting popups even with popups disabled? I’m sorry. That is definitely not supposed to be happening. There should just be the recipe video that scrolls with you (it does show an ad before playing), but doesn’t really cover the screen. When we test it, it never pops back up a second time. I’ll work on it and see if I can get it fixed.

      2. I agree with Laurie and everybody else with the pop UPS it’s but it’s insane it’s very difficult to use and to read and look up to use and to read and to concentrate way too many

    1. Karly Campbell

      4 ounces of cheese = 1 cup of shredded. The package you will buy will tell you the weight. It’s pretty easy to just eyeball it…a little more or less won’t hurt.

  2. Nicola Richards

    This looks amazing and so versatile. What’s the best way to store it and how long for please?

    1. Karly Campbell

      We just store it in a jar or bowl in the fridge. I wouldn’t keep it more than 4-5 days.

  3. This was delicious! I added a bit of garlic butter, bought at Sam’s, gruyere, and colby jack as that is what I had with a pinch of parm. So incredibly delicious!

  4. This was so good. I used only cheddar and mustard from the fridge. I used it for eggs Benedict. There’s plenty left to use on vegetables later. Yum! So easy, too. Thank you very much.

  5. I used your recipe tonight over roasted fresh asparagus with bacon bits. Oh my, Karly!!! This is a winner in my book!! I used cheddar & Colby then also added mustard (no powder), turmeric, pepper & onion powder. Delish!!! And quick & easy! Thx so much!

  6. Does it work with 2% milk? An is there another seasoning I could use? I am on quarantine and I do not have heavy cream or Mustard.

    1. Karly Campbell

      I’m not sure this would work with just plain milk – the cream helps it stay thicker and heats up so nicely. But you can try! I’d just leave the mustard out.

  7. I did this tonight and I cannot thank you enough. Mine was just cauliflower cheese but, it was awesome xxx

  8. Linda Hogan

    Just made this. It was amazing! Super easy. Serve over cauliflower rice,sauteed zucchini,peppers,onions, asparagus and shrimp. Yummmy.

  9. This is so good! We made it a tiny bit thinner for soup. We added broccoli, shirataki rice and ground beef. Was like eating a tasty soup. The hubby added crushed ritz on his.

  10. I made this and it was perfect! For those who are having a hard time, turn down the heat. Slow and steady wins the race. This cheese sauce is simply bliss. Thank you for sharing!

  11. Delicious! Very smooth and creamy and flavorful with the dry mustard. I did add a pinch of cayenne to enhance the cheese. Wonderful over steamed broccoli and cauliflower.
