Roasted Cauliflower Steaks

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions, to ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

If you have never tried roasting cauliflower in the oven (or air fryer) before you are missing out! It’s my new favorite way to cook this humble vegetable!

The roasted cauliflower steaks recipe I’m sharing here works well as a side dish with roast beef (or indeed any roast meat), or as a main dish for vegetarians (and vegans if you use vegan cheese).

There is a little spicy kick from some red crushed pepper flakes, and you can finish the dish off with a sprinkling of fresh herbs and some toasted pine nuts if desired.

In fact, this is a dish you could customise so easily to your personal tastes, and enjoy roasted cauliflower in a variety of different ways.

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online. Staple ingredients such as oil, salt, sugar, etc., aren’t always included here as you’re likely to have those in your kitchen. The complete list of ALL ingredients with measurements is found on the recipe card.

  • Fresh ProduceCauliflower, Garlic
  • DairyParmesan (leave this ingredient out if serving to vegans)
  • Italian Seasoningthis recipe uses store-bought Italian Seasoning, but it is so easy to make your own herb mixes, especially if you already have a bunch of herbs and spices in your pantry already. Just mix equal measures of dried basil, oregano, rosemary, parsley, and thyme. You can also add a pinch of garlic granules or powder as well as red chili flakes if you like. Store in an airtight jar and use in recipes as required. Or grab our Italian Seasoning Recipe here.
  • Crushed Red Pepper Flakes

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
