For the cauliflower steaks:

• Cauliflower
• Olive oil
• Garlic powder
• Smoked paprika
• Salt
• Black pepper
• Red pepper flakes (optional)

For the herb sauce:

• Fresh parsley
• Fresh cilantro
• Garlic
• Lemon juice
• Olive oil

Directions

1. Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
2. Remove the outer leaves from the cauliflower and trim the base, keeping the core intact.
3. Cut the cauliflower into 3/4-inch thick slices to form “steaks.” You should get about 2–3 full steaks; smaller florets can be roasted alongside.
4. Arrange the cauliflower on the prepared baking sheet. Brush both sides generously with olive oil.
5. Season with garlic powder, smoked paprika, salt, black pepper, and red pepper flakes if using.
6. Roast for 20–25 minutes, flipping halfway through, until golden brown and tender.
7. While the cauliflower roasts, prepare the herb sauce. In a blender or food processor, combine parsley, cilantro, garlic, lemon juice, olive oil, and salt. Blend until smooth.
8. Drizzle the herb sauce over the roasted cauliflower steaks before serving. Garnish with chopped herbs or thinly sliced radish if desired.

FAQs

How do I keep the cauliflower steaks from falling apart?

Be sure to keep the core intact when slicing. A sharp knife and a firm cauliflower head help maintain the steak shape.

Can I make this dish ahead of time?

Yes, roast the steaks and prepare the sauce in advance. Reheat the steaks in the oven and drizzle with sauce before serving.

What’s the best substitute for cilantro?

You can use extra parsley, basil, or mint depending on your flavor preference.

Can I use frozen cauliflower?

Fresh cauliflower is recommended, as frozen tends to be too soft and may not hold together well when sliced.

How thick should the steaks be cut?

Cut them about 3/4 inch thick to allow them to roast evenly without becoming too soft or burning.

Is this recipe spicy?

It’s only mildly spicy with the optional red pepper flakes. You can adjust or omit them to taste.

What can I serve with cauliflower steaks?

Serve with quinoa, couscous, roasted chickpeas, or a simple green salad for a complete meal.

Can I use a different oil for roasting?

Yes, avocado oil or grapeseed oil are good alternatives with high smoke points.

How do I make the sauce creamier?

Add a tablespoon of avocado or a spoonful of yogurt (dairy or plant-based) to the herb sauce for extra creaminess.

Can this recipe be doubled?

Absolutely. Use two baking sheets to ensure the cauliflower roasts evenly without overcrowding.
