In my experience, most people either love cauliflower or hate it. I’ve always loved it, even when I was a child. My mom used to steam it and I would devour it floret after floret.

Now I rarely eat cauliflower steamed because I enjoy it so many other ways. My mashed cauliflower and cauliflower stuffing are wonderful low carb side dishes, but nothing compares to roasted cauliflower.

Roasting caramelizes the cauliflower, which brings out its natural sweetness and promotes browning.

The caramelization make this dish absolutely irresistible.

Roasted cauliflower recipe ingredients

Ingredient notes

  • Cauliflower. Cut the cauliflower into small- to medium-sized florets. Try to make the florets roughly the same size for even cooking. Using a whole head is more cost effective, but you may also purchase pre-cut cauliflower and cut the florets so that they’re the same size.
  • Garlic. Roasted garlic has a sweet, mild flavor that pairs beautifully with the cauliflower. Leave the garlic cloves whole and unpeeled, then squeeze them from the skins before serving.
  • Shallots. If you’ve never tried shallots, they’re very mild in flavor and are very sweet when they’re roasted. They can be substituted with your favorite onion if you prefer.
  • Parmesan. I recommend buying a block of parmesan cheese and grating it yourself for the best flavor and texture for this recipe. Omit the cheese to make this recipe vegan.

How to roast cauliflower

This roasted cauliflower recipe is so easy to make and is sure to be a hit with everyone in the family.

Pro tip: Be sure to spread the ingredients in an even layer and don’t overcrowd the pan to prevent the vegetables from steaming and becoming mushy. Use two sheet pans if necessary and roast on the oven racks in the upper and lower thirds of the oven.

FAQ’s

How do you roast cauliflower without it getting mushy?

Blot the cauliflower florets dry after washing, and be sure spread them out in an even layer in the baking sheet. Don’t overcrowd the pan as this will cause the cauliflower to steam and become soft and mushy.

How long to roast cauliflower?

This roasted garlic cauliflower is done in about 25-30 minutes in a 425 degree oven, depending on the size of the florets. It’s done when it’s tender and caramelized.

Can you roast frozen cauliflower?

Frozen cauliflower may be roasted, but I prefer to use fresh cauliflower as it has a better texture when cooked. Frozen cauliflower tends to become mushy when roasted.

Serving suggestions

This roasted cauliflower recipe is extremely versatile and may be paired with any of your favorite main dishes such as baked salmon, oven baked pork chops, pan seared steak and spatchcock chicken.

It’s also great as a vegan or vegetarian main dish served in tortillas or with quinoa or your favorite pasta.
