  • Healthy

Ingredients you will need for this recipe

  • Cauliflower: A full head of cauliflower makes about 3-4 cauliflower steaks.
  • Lemon Juice: This literally tastes so good! Drizzle a little bit over the cauliflower steaks and it literally will do wonders I promise. Plus some extra vitamin C! Win/Win!
  • Olive Oil: I used olive oil because it goes so well with the cauliflower. However, if you don’t like olive oil or want to use another oil for some reason, go ahead!
  • Spices: Spices like onion powder, garlic powder and a tiny bit of nutritional yeast will definitely bring these steaks to the next level!
  • Fresh Herbs: Fresh herbs are always a winner and help to boost the flavor. Don’t skip them!

How to cut cauliflower into steaks

  • Cut off the outer green leaves.
  • Make sure to trim to the bottom of the stem but also keep the core intact.
  • Start by cutting right through the cauliflower head and then continue to cut smaller pieces. Depending on the size of your cauliflower, you will get approximately 3-4 steaks out of it.
  • Make sure that your slices are thick. They might fall apart otherwise.
  • Don’t waste the excess cauliflower. You can roast the excess pieces in the oven as well or make cauliflower rice!

I highly recommend using a large chef’s knife for trimming the outer leaves and cutting your cauliflower steaks. Just be careful to not cut yourself.

How to prepare cauliflower steaks

Once the cauliflower steaks are all cut, it is time to prepare the cauliflower steaks. This process is quite simple and mostly requires pantry friendly ingredients.

Step 1: Start by adding the spices to your cauliflower first. I added a little bit of garlic and onion powder, nutritional yeast, salt and pepper as well as a drizzle of lemon juice.

Step 2: Brush or drizzle some olive oil on the cauliflower.

Step 3: Repeat Step 1 + 2 for the other side of the cauliflower. Make sure that both sides are evenly coated with spices, lemon juice and olive oil.
