But my current obsession is steamed broccoli with cheese sauce.

I mean, does it get any better than a pile of veggies topped with a decadent creamy cheese sauce? Nope!

It’s good on cauliflower too!

How to make cheese sauce:

Homemade cheese sauce is so simple and starts with just a few ingredients: heavy cream, cream cheese, cheddar, Gruyere, and mustard powder.

I like the flavor that Gruyere cheese adds to this cheese sauce, but you can definitely sub in whatever cheese you prefer! Monterey jack is mild and creamy, Parmesan will give it a salty kick, and Pepperjack will add a little spice.

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.

Turn the heat off and add your freshly grated cheddar and Gruyere.

Start stirring until the mixture is fully melted, smooth, and creamy!

That’s it!

This sauce will start to thicken as it cools, so serve warm.

To reheat, just add a splash more of cream and microwave in short bursts, stirring as needed.

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?
