What ingredients do you need for this recipe?

• large head of cauliflower
• olive oil
• salt and fresh ground black pepper to taste

What are Cauliflower Steaks?

Cauliflower steaks are thick slices of cauliflower that are roasted, grilled, or fried and often served with some kind of sauce or topping.

Are Cauliflower Steaks hard to make?

The hardest part of this recipe might be slicing the cauliflower steaks so they don’t fall apart, so buy the biggest cauliflower you can find. I recommend that you cut through the core of the cauliflower to keep the pieces intact. But even if some of your cauliflower ends up in pieces instead of slices, I promise you that this will still be delicious!

What other topping variations can you use for the roasted cauliflower steaks?

There are an endless number of options for varying the topping that goes on the cauliflower steaks. If you use the topping in this recipe, you can switch out the Kalamata olives for regular black olives if you prefer. Some people also might want to skip the capers. You could also use the toppings from Chicken Bake with Olive and Caper Sauce or top the cauliflower pieces with Avocado Salsa or Mediterranean Salsa for some other variations.

How to make Roasted Cauliflower Steaks with Red Pepper, Capers, and Olives:

(Scroll down for complete printable recipe including nutritional information.)

1. Cut a head of cauliflower into slices about 3/4 inches thick.
2. I cut through the core of the cauliflower to keep the pieces intact, and then cut some of the core away afterwards.
3. Lay the cauliflower slices in a single layer on a roasting pan. It’s important that the pan isn’t crowded.
4. Drizzle both sides of the cauliflower with olive oil and season liberally with salt and fresh ground black pepper.
5. Roast cauliflower in a 450F/220C oven, cooking without turning for at least the first 15 minutes.
6. After about 15 minutes, remove cauliflower from the oven and carefully turn cauliflower pieces with a large turner.
7. Put back in oven and roast 10-15 minutes more, or until cauliflower is slightly crisp and nicely browned, and done to your liking.
8. While the cauliflower roasts, mash 1/2 tsp. Minced Garlic with some salt. I used a mortar and pestle, but you can do this in a bowl with a fork.
9. Put the garlic and salt into a bowl with lemon juice, (I rinsed out the mortar and pestle with the lemon juice), then stir in olive oil, whisking until the vinaigrette is emulsified. 
10. Then mix in the chopped olives, diced red pepper, and capers, and let dressing sit so the flavors blend while the cauliflower finishes roasting.
11. When the cauliflower steaks are crisp and slightly browned, spoon the spicy garlic dressing mixture over the cauliflower pieces and serve hot.

Ingredients

• 1 large head cauliflower
• 2 T olive oil
• salt and fresh ground black pepper to taste
• 1/2 tsp. minced garlic
• pinch sea salt
• 3 T fresh-squeezed lemon juice
• 3 T extra-virgin olive oil
• 1/4 cup finely chopped Kalamata olives (optional, see notes)
• 1 red bell pepper, chopped small
• 1 T capers

Instructions

1. Preheat oven to 450F/200C.
2. Remove leaves from cauliflower, then use a large knife to cut the cauliflower into slices an even 3/4 inch thick, slicing through the core to make the cauliflower "steaks."
3. Cut core section away from the slices and arrange cauliflower slices in a single layer on a baking sheet. (Don’t worry if some piece break off; they will still taste great!)
4. Drizzle both sides of cauliflower with olive oil and season with salt and fresh ground black pepper. (I used a generous amount of pepper, but not too much salt.)
5. Start cauliflower roasting while you make the vinaigrette, and let it roast 15 minutes without turning.
6. While cauliflower roasts, mash garlic and sea salt in a mortar and pestle (or use a fork and a bowl), then rinse the garlic and salt mixture into a bowl with the lemon juice.
7. Stir in the olive oil, whisking until the dressing is emulsified. Stir in chopped red peppers, capers and olives and let the vinaigrette ingredients blend while cauliflower continues cooking.
8. After about 15 minutes, remove cauliflower from the oven and carefully turn cauliflower pieces with a large turner.
9. Put back in oven and roast 10-15 minutes more, or until cauliflower is slightly crisp and nicely browned, and done to your liking.
10. Serve hot, with the garlicky dressing mixture drizzled over cauliflower

Notes

You can use plain black olives if you prefer, or skip the olives completely.
