I’ve been roasting vegetables like it is my job (wait…I guess it kind of is my job?) and we LOVE them this way. Cauliflower is no exception! Roasted broccoli is amazing, roasted carrots are amazing, mushrooms, squash, etc. You get the point. Roasting brings so much flavor and texture into most vegetables.

It really is the best way to eat cauliflower.  And it is unbelievably easy, which is always a bonus.

Once you learn the basics of how to roast cauliflower, you’ll find yourself doing it constantly! Make sure to try my Parmesan roasted cauliflower, too. I also LOVE these roasted cauliflower nachos!

Tip: The recipe is written for 425°F but if you need to roast it at a lower temperature, like 400°F or even 350°F, you may do so. It won’t cook as quickly and it may not get quiiiiiite as crispy, but it will work if you have something else in the oven that you need to cook at a specific temperature.

I use roasted cauliflower in other recipes, too. Even though the cauliflower is blended together with other ingredients, roasting it first gives your dish an amazing depth of flavor. Everyone will want to know your secret, and how to roast cauliflower! 

Try this cauliflower cheddar dip — it’s a healthier alternative to heavy all-cheddar dips. Similarly, roasted cauliflower and cheddar soup tastes unbelievably rich but won’t break your calorie count for the day.

How to Roast Cauliflower in 3 simple steps:

  1. Wash cauliflower, cut into small florets, and dry as much as possible. I give the florets a spin in my salad spinner. The smaller and the drier they are, the crispier they’ll get and the quicker they’ll cook.
  2. Toss with olive oil, salt and pepper.
  3. Spread on a baking sheet (give them as much space as possible!) and roast at 425°F until crispy and golden brown!

As always, keep reading for directions and a printable recipe!
