This Roasted Cauliflower Recipe changed my husband’s mind about this once-maligned vegetable! The caramelized florets are sweet, tender, and irresistible!  Now he and I both nibble on the tasty florets before they make it to the serving dish!

Oven Roasted Cauliflower enhances the natural sweetness and makes an absolutely delicious side dish with nutty, buttery undertones.

By now, many of you know that I have a husband with a picky palate.  Slowly, over our nearly 35-year marriage, I’ve gotten him to try and actually enjoy broccoli, asparagus, the occasional zucchini (he still calls it cucumber!), and just lately, cauliflower.

It was this roasting method that finally swayed him.  This Roasted Cauliflower may convert your cauliflower avoider into a lover, too!

Tips for Roasting Cauliflower

I’ve learned a few tricks to help make your first and subsequent attempts at roasting cauliflower, or other vegetables, utterly delicious!

  • Cut your cauliflower into small florets, about 1/2 to 1-inch pieces. You want all pieces to be approximately the same size. I discard excess core and stems, but you can roast them, too or save for making soup or cauliflower rice.
  • Wash your cauliflower ahead of time, so it has a chance to dry. The oil won’t stick well to damp florets.
  • Place the dried florets in a large bowl, add the oil and toss to coat every single piece. I realize it’s an extra bowl to clean, but it really helps get each floret coated well with oil. Then add the Parmesan and bread crumbs and toss again.
  • Use a large sheet pan to roast the cauliflower so the florets aren’t crowded together. If they’re too close, they tend to steam instead of roast.
  • Sprinkle with kosher salt and freshly ground pepper. Remember the Parmesan is salty, so don’t go overboard, but it’s still important to add salt.
  • Roast at high heat for best results, 400-450º.
  • Make sure you toss the cauliflower about halfway through the cooking time. That helps as much surface area to brown as possible.

The Nutritional Benefits of Cauliflower

We all know the vegetables are good for you and that a balanced diet should include loads of fruits and veggies. But did you ever wonder about the specific benefits that come from eating cauliflower? Well, there are plenty!

  • Cauliflower is high in fiber. In fact, there are 3 grams of fiber in every cup. You might not want to eat a cup of raw cauliflower, but sweet, roasted cauliflower is another story!
  • This vegetable is also rich in nutrients, especially Vitamin C!! It’s also a source of Folate, B6, Vitamin K, Magnesium, Potassium, and more.
  • Cauliflower contains Choline which is needed for memory and learning.
  • Cauliflower is full of antioxidants that help rid your body of free radicals along with decreasing inflammation and possible protection against cancer.
  • This cruciferous vegetable can help with weight loss. As a substitute for rice, cauliflower rice is a tasty low carb option. High in fiber, cauliflower also helps fill you up, helping to minimize overeating.

Oven Roasted Cauliflower Recipe

Vegetables caramelize and sweeten when cooked with intense, dry heat.  I will never steam cauliflower again. The addition of Parmesan and bread crumbs just provides additional flavor and texture.  Bill and I sneak bites right off the baking sheet when it’s fresh out of the oven. It’s just that good!

I’m still working on my 17-year-old, but I’m sure he’ll be converted into an oven-roasted cauliflower fan one of these days! He’s nowhere as persnickety as his father, so I have high hopes! If you make tiny florets when you roast your cauliflower, you will have popcorn cauliflower, and it’s as addictive as it’s namesake!

Three Keys for Roasting Cauliflower

There are 3 keys for oven-roasted cauliflower. First, the oven must be hot. 400º works well, but you can also crank your oven to 425-450º if you’d like even more browning. Just watch carefully. Put your cauliflower on the lowest rack as this helps the bottom of the florets brown, too. And last, but also very important, is to have the cauliflower in a single layer so that it roasts instead of steams.

Frequently Asked Questions

Can You Roast Frozen Cauliflower?

Yes, but roast it from the frozen state instead of defrosting first. You want it to steam, not roast. You will not be able to add toppings, and fresh is preferred, but frozen works in a pinch.

How Do You Reheat Roasted Cauliflower?

At our house, we microwave the leftovers to reheat. But if you'd like to bring back a little crispiness, sauteing the leftovers in a skillet is a better option.

Is Roasted Cauliflower Low-carb?

If you roast your cauliflower with just olive oil and Parmesan, it's definitely low-carb. Once you add the bread crumbs, the amount of carbs per serving does increase.

Can You Freeze Roasted Cauliflower?

You can freeze simple roasted cauliflower without any toppings, but this version would not defrost well.
