Mashed Cauliflower with Roasted Garlic

If you’re looking for a new side dish with a trusted, nutritional that vegetable we all love (cauliflower!) that happens to be delicious, then you’re at the right place!

This cauliflower dish is incredibly loaded with flavor and it’s very similar to mashed potatoes, without the starch.  Although it is a lot like mashed spuds, it still has its own unique and wonderful taste.  This is wonderful served with Honey Bourbon Baked Ham!

How To Make Mashed Cauliflower with Roasted Garlic

This dish is really surprisingly easy to put together.

There is just a little prep work and then the rest is a snap.

 

How To Roast Garlic

Roasting garlic has to be one of the simplest culinary creations of all time.

As the head of garlic gently roasts in a 350°F oven, the cloves are transformed into a buttery, milder garlic smear that is incredible.

EXPERT TIP: All you need to do is very carefully cut away the top of a head of garlic. Don’t worry if you don’t cut the tops off of every single clove. And don’t worry if some, or even most, of the cloves fall off. Place them all in a square piece of foil, squirt a little olive oil over them, wrap it up, and bake in the oven at 350°F for 1 hour.

How To Cut Up a Head of Cauliflower

Cutting up a head of cauliflower is very similar to cutting up a head of broccoli. By the way, cauliflower is loaded with nutritional value…read more about that here.

Very carefully, and slowly, cut away the core with a nice sharp, large knife.

IMPORTANT NOTE: ALWAYS keep the blade of the knife pointing away from your hand(s). You can also cut the cauliflower down the middle, and then start cutting away the core. Then, use your hands, or the help of your knife, to cut the cauliflower into small to medium-sized florets.

Now, it’s time to steam the cut cauliflower.

We love using our bamboo steamer, but any method you have for steaming will work perfectly.

You can even steam them in a pot with a small rack at the bottom and about 1 cup of water. Cover and steam over medium heat for about 20 to 25 minutes, or until soft.

Building Layers of Flavor

For ease, we place the steamed cauliflower into our large food processor. But you can also mash the mixture in a mixer, with a hand mixer, or even a wooden spoon and a good amount of elbow grease.

After the garlic has cooled enough for you to handle, use your fingers to squeeze the roasted garlic from the skins onto the steamed cauliflower.

EXPER TIP: The roasted garlic taste is not overpowering, however, if you make the mashed cauliflower a couple of days in advance, we do find that the garlic taste becomes a little more pronounced as it sits in the fridge.

Next, come the unsalted butter and the Parmesan cheese.

Then the broth. We use vegetable broth, but you could use chicken broth if you prefer.  We find ¾ cup of broth makes the perfect consistency of the mashed cauliflower.  But, pour some in, mash or purée, and then test consistency.  Depending on how thin, or thick, you like your mash, will depend on how much broth you add.  

Our Mashed Cauliflower with Roasted Garlic is great for the Keto diet. To make the dish vegan, simply use almond butter in place of the butter and Parmesan cheese.

When To Serve Mashed Cauliflower with Roasted Garlic

You can serve this dish as a substitute for any time you would be serving mashed potatoes.

It’s perfect for feasts, such as Thanksgiving, but it’s also so simple to prepare, it makes a wonderful side dish for a busy weeknight meal.

It also makes a wonderful complement to luxurious dishes such as Wagyu Smoked Beef Short Ribs (recipe to come). Just make a bed of the cauliflower on the plate, and then place the ribs over the top. Sublime.

No matter how you serve it, folks will be going back for more and more, it’s really that delicious.

Notes

The roasted garlic can be made up to 2 days in advance.  Squeeze the roasted garlic from the skins of each clove and place in an air-tight container and keep in the fridge until ready to use.
You can use bagged pre-cut cauliflower found in the produce section.  We don't recommend frozen cauliflower because the texture will be a little too soupy, but the taste will still be good, just we feel the texture won't be right.
You'll need about 8 to 10 cups of florets, this usually comes from 2 medium-sized heads of cauliflower.
The mashed cauliflower can be made up to 1 day in advance, and then gently reheated on the stove over medium-low heat.   We have found that when made in advance, or when reheating leftovers, the roasted garlic taste becomes somewhat more pronounced.
To make this completely vegan, use almond butter in place of the butter and Parmesan cheese.
