We don’t know about you, but cheese just seems to make everything better. While we’re partial to plant-based cheeses lately, this classic Keto Cheese Sauce is perfect for when you’re craving a little dairy. This cheese sauce is smooth and creamy, not lumpy like a lot of lower carb cheese sauces, and it’s perfect for so many things.

We even give options below on how to make this cheese sauce vegan AND low-carb, it’s a win-win! There’s also no need for fancy contraptions (we do love our contraptions though 😉 ) but you won’t need an Instant Pot or Slow Cooker for this easy recipe, just a single cast-iron skillet, the truth Swiss Army Knife of the kitchen.

Our favorite way to serve this Keto Cheese Sauce is to drizzle it over steamed broccoli that’s also been drenched in garlic butter. HOLY FREAKING YUM. Seriously, you’ll never want anything other than broccoli again 😉 It’s a great way to get kids to eat some green goodness.

Obviously, you could also recreate your high school years and make football stadium-style nachos with some low-carb Quest tortilla chips and some pickled jalapeño slices. Fun times 😆 We’re all for a junky nostalgic recipe.

Read on for all of the details and helpful tips and tricks to make this easy recipe come together in a flash!

  • 4 tablespoons unsalted butter
  • 10 ounces heavy cream

How to make Keto Nacho Cheese Sauce

  1. Heat a 10” or larger cast-iron skillet over medium heat. Melt butter in a skillet, add in heavy cream, stir to warm, but don’t boil. Slowly add in cream cheese in small chunks, stirring constantly, until cream cheese is melted and smooth.
  2. After cream cheese is completely incorporated, add in the cheddar cheese, stirring constantly to combine until melted.  Add in taco seasoning to taste*. Serve immediately.
  • If not using the taco seasoning, add the cheese then the salt and pepper to taste. This is perfect if you’re serving the cheese sauce over broccoli and not a Mexican-inspired dish.

How to make this low carb keto recipe vegan/dairy-free

To make this Keto Cheese Sauce dairy free and vegan, make the following swaps:

How to store leftovers

Store the leftovers in a lidded jar or container in the refrigerator for up to 5 days. To reheat, place the cheese sauce back into your skillet over medium heat. Maybe add a splash of cream (or almond milk if making this vegan) to thin the sauce out just a bit if it has thickened while refrigerated. Bring to a simmer for just a minute while whisking until smooth.

To make sure that the leftovers stay good for longer, always use a clean spoon to remove the amount you need from the container.

How to make a Queso Blanco style Keto Cheese Sauce

We love a good cheddar sauce but we really LOVE a queso Blanco style cheese sauce for Mexican style dishes like nachos and burrito bowls. To make a queso Blanco style sauce, simply use shredded Monterey jack cheese instead of the cheddar.

Following our vegan instructions? We adore Violife Smoked Provolone for a queso Blanco. It tastes SO similar to the white cheese sauce we’re used to at our favorite Mexican restaurants.

We usually mince up a jalapeño and add it to the sauce as well. YUM!
