I have been roasting a lot of veggies lately trying to recover from the gluttonous sweet-eating I indulged in over the holidays. I absolutely love roasting vegetables because it’s so easy and versatile. Last week I shared my favorite roasted vegetables recipe with mixed veggies but today I’m keeping it super simple with this delicious and easy recipe!

Prep work

Slice the head of cauliflower in half with a sharp knife. Cut each half in half again to make quarters. Use your knife to carefully cut the florets free of the base. Try to keep the florets an even size for the best roasting results.

Roasting step by step

Roasting cauliflower is very easy, fast and simple to customize to your own taste. You simply toss the cauliflower with olive oil and salt and pepper.

After you toss the cauliflower you roast it for about 20 minutes, then toss it on the pan and roast an additional 20 minutes. If you are adding cheese to the basic roasted cauliflower I bake for 25 to 30 minutes then toss and top with cheese, then bake an additional 10 to 15 minutes.

It’s hard to imagine making a recipe any more simple than this one. It turns out perfectly though. You can use either shredded or grated Parmesan cheese to make this side dish also. Or even experiment with other cheeses like Asiago! It’s perfect for low carb or keto diets as well.

Flavor Variations

There are endless possibilities when it comes to seasoning this recipe. Always start with the olive oil, salt, and pepper as the base. From there you can experiment with adding spices such as garlic powder or curry powder. Try squeezing lemon juice over the cauliflower after laying on the baking sheet. Other spices to try are:

  • Italian seasoning
  • Cajun seasoning
  • tumeric
  • cumin
  • chili powder
  • red pepper flakes


How do you choose a head of cauliflower?

Choosing a good head of cauliflower will ensure this recipe turns out perfectly! You want to pick cauliflower that is firm and heavy. Make sure there are no brown or soft spots before you purchase it. The leaves should be fresh and bright green.

How do I store it before roasting?

Cauliflower can go bad easily if not stored properly. When you get home with your fresh cauliflower, unwrap it. Keeping it wrapped traps moisture that can make it go bad faster. Place the unwrapped cauliflower in a gallon plastic bag. Add a paper towel to the bag to help absorb excess moister. Store in your crisper drawer in the refrigerator 4-6 days.

This recipe pairs wonderfully with this Steakhouse Steak in the Oven or Easy Baked Chicken Breast. I hope you enjoy it!
