By on August 1, 2022

While most people boil, steam, or even microwave cauliflower to serve alongside their main meal, there are several other ways to prepare veggies if you’re looking for something different. So, with this in mind, can you roast cauliflower? 

To roast cauliflower, season your cauliflower with salt, pepper, oil, and any other herbs and spices that take your fancy before roasting it in the oven until it’s nice and crispy

How to Roast Cauliflower

You’ll be pleased to hear that roasting cauliflower is easy, and there’s not much finesse required in the kitchen! When you’re sure that you’ve got a fresh cauliflower to work with, you will need to follow these steps to ensure you roast it successfully: 


  1. Preheat Oven
    Switch on your oven and preheat it to 450F or 230C. 
  2. Prepare Cauliflower
    Rinse your cauliflower under the cold tap and pat it dry. Then, slice the florets into the size that you require. You don’t want to chop them too finely, or they will burn. You’ll also want them to be the same size.
  3. Season
    Place your chopped cauliflower in a sieve and season well with olive oil, salt, and pepper, shaking it well to ensure each floret is covered. You can also add other herbs and spices like garlic and chilli at this stage to make it even more flavoursome.
  4. Place on a Baking Tray
    Line a baking tray with greaseproof paper and spread your seasoned cauliflower out on top of the tray, ensuring it’s well spaced. 
  5. Roast
    Add your tray of cauliflower to the centre of the oven and roast until it’s golden and tender. This should take around eighteen minutes. 
  6. Serve and Enjoy
    Your delicious roasted cauliflower will now be ready to serve and enjoy alongside your chosen accompaniments. 
Why is My Roasted Cauliflower Mushy?

If you overcrowd the tray with cauliflower florets, they will become mushy as there will be no space for the heat to circulate. If you use too little fat, you’ll also find the cauliflower does not crisp up properly. Spaced Out Cauliflower Roasting

How to Roast Cauliflower Successfully

If you want things to go well when roasting cauliflower, give these 3 quick tips a read first:

  • Season Well – You don’t need us to tell you that cauliflower can taste a little bland if you don’t season it well! You can use many things to bring your roasted cauliflower to life, but a simple combination of chilli and garlic should do the trick alongside the salt, pepper, and oil mix. You could also season it with spices such as paprika and cayenne pepper. 
  • Don’t Overcrowd the Tray – When spacing out your cauliflower on the baking tray, ensure it’s well-spaced and not overcrowded. If your cauliflower roasts unevenly, it will cause it to go soggy and mushy as opposed to crispy, which we’re sure you would hope to avoid. 
  • Use Low-Fat Cooking Spray – To prevent your roasted cauliflower from being too unhealthy, opt for a low-fat cooking spray instead of olive oil or full-fat vegetable-based cooking oil. This will keep the calories low and ensure you can enjoy roasted cauliflower without the associated guilt.
