ingredients for whole roasted cauliflower
  • Cauliflower – A medium-sized cauliflower head with no blemishes or brown patches. Depending on the size of your cauliflower, adjust the baking time to make sure it’s cooked properly.
  • Butter – use unsalted one. If you choose to use a salted one, then you need to reduce the amount of salt.
  • Olive Oil – This is a flavorful oil. However, if you don’t have this kind of oil in your kitchen, you may substitute it with avocado oil.
  • Italian Seasoning
  • Garlic – If you don’t have fresh garlic, you can use garlic powder as well.
  • Parmesan Cheese – you can skip this ingredient if you want, but trust me, it’s your loss.
  • Fresh Parsley
  • Salt and Pepper – to taste.

Tips For Making The Best Whole Roasted Cauliflower Recipe

  1. The spices in this recipe can be replaced with your favorite ones. It all comes down to personal choice. Remember that experimenting yields the most extraordinary outcomes! The next time will always taste better.
  2. Bake for the first 35 minutes and then roast for 15-20 minutes for a crispier result.
  3. To check if the cauliflower is ready, I recommend using a knife to check for doneness, gently piercing the cauliflower.

Can I Make This in An Air Fryer?

Sure! Air fryers have become far more popular recently and for a good reason. It helps you cook quick and delicious recipes with an incredible crispy finish every time and eliminate recipes that require frying in a lot of oil.

Air Fryer Whole Roasted Cauliflower

If you want to make this on-air fryer, there is not a problem.

quick cauliflower recipe
  1. All you have to do is grease an Air Fryer Basket, then place the whole cauliflower head into it.
  2. Set the air fryer to 350 degrees Fahrenheit and set a timer for 30 minutes.
  3. While it’s in the air fryer, keep an eye on it to ensure it doesn’t overcook.
  4. When the time is up, remove the cauliflower. You will end up with a beautiful warm golden brown head of cauliflower that tastes incredible.

How To Store This Whole Roasted Cauliflower

  • You can store it in the fridge, in an airtight container, for up to 5 days. Reheat in the microwave for about 3 minutes. Personally, I like to eat it cold, because it’s good anyway. Awesome, right? 
  • After baking, you can choose to freeze the whole roasted cauliflower head. Simply cut it into slices or pieces, set it aside to cool thoroughly, and store it in an airtight container.

Or, if you have any leftovers of this recipe, the great idea is to make some mac and cheese with it.
