It’s so wonderfully cheesy and delicious! And it’s ready in just 30 minutes, making it a great choice for a weeknight dinner.

Ingredients

You’ll only need a few simple ingredients to make this tasty side dish. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:

Fresh cauliflower: Cut into small florets. I haven’t tried making this recipe with frozen cauliflower, but I suspect that fresh is the way to go for the best flavor and texture.Heavy cream: I tried to make this recipe with half-and-half. Nope. Heavy cream is definitely better.Dijon mustard: This traditional French mustard is creamier, thicker, and less vinegary than yellow mustard.Spices: I use garlic powder and cayenne pepper. The cayenne adds a very subtle kick. The dish is not spicy.Shredded cheddar cheese: I prefer extra-sharp cheddar. I think it gives this dish a wonderful flavor.Black pepper to finish the dish: freshly ground tastes best.

Instructions

Making cauliflower mac and cheese is easy! It takes 5 minutes to trim the cauliflower and divide it into small florets. Then, it takes about 7 minutes to steam the cauliflower in the microwave until tender-crisp. When the cauliflower is ready, place it in a serving dish, cover it (or keep it in the oven on “warm”), and make the cheese sauce. Making the cheese sauce is so easy! Simply heat some heavy cream with seasonings, then gradually mix in the cheese, stirring over low heat just until it melts and the sauce thickens. The last step is to pour the sauce over the cauliflower florets and gently mix. That’s it!

Expert tip

There’s no need to add flour to the sauce to thicken it. The sauce thickens beautifully even without flour. I suspect that using store-bought pre-shredded cheese helps the sauce thicken, because of the anti-caking agent added to these cheeses (powdered cellulose in the Whole Foods brand).If you’re shredding your own cheese and you feel that the sauce is too thin, I suggest simply adding more cheese. Try ¼-1/2 cup.Another option is to mix a teaspoon of gluten-free cornstarch with a teaspoon of cold water and add that to the sauce. Increase the heat to medium so that the sauce bubble gently, and mix until the sauce does thicken.The small amount of cornstarch only adds about 2 grams of carbs for the entire dish and it does help to thicken the sauce. And unlike flour, you don’t need to use a significant amount, so you won’t taste the starch in the sauce.

Frequently asked questions

Variations

The best way to vary this recipe is to add various spices and herbs. Try adding a pinch of dried thyme - it’s really good. Sometimes I add a pinch of smoked paprika for a lovely smoky flavor. You can also use different cheeses instead of cheddar. Good options include Colby, Gruyere, and Gouda.

Serving suggestions

I like to serve this cauliflower mac and cheese with hearty meat dishes such as beef back ribs and hamburgers. It’s also good with these baked drumsticks.

Storing leftovers

You can keep the leftovers in the fridge, in an airtight container, for up to 3 days. Reheat them, covered, in the microwave. You can also freeze this dish for up to three months. I recommend freezing it in microwave-safe containers, in individual portions, then microwaving those portions.
