Step 1: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup. This step is crucial for achieving that perfect roasted texture for your cauliflower steaks.
Step 2: Prepare the cauliflower. Remove the tough outer leaves from the cauliflower. Trim the bottom stem, but ensure you leave enough of the core intact to hold the head together. Place the cauliflower stem-side down on a cutting board. Carefully slice the cauliflower into four 1-inch thick “steaks” from the center. Don’t worry if some florets break off; these can be roasted alongside the steaks and make for delicious little crispy bites.
Step 3: Arrange the cauliflower steaks on the prepared baking sheet. Drizzle with 2 tablespoons of olive oil, ensuring both sides are lightly coated. Sprinkle evenly with smoked paprika, garlic powder, salt, and black pepper. Flip the steaks and season the other side. This even seasoning will ensure every part of your Cauliflower Steaks with Chimichurri is bursting with flavor.
Step 4: Roast for 20-25 minutes, then carefully flip the steaks. Continue roasting for another 10-15 minutes, or until they are deeply golden brown, tender when pierced with a fork, and have deliciously crispy, caramelized edges. The exact cooking time will depend on the thickness of your steaks and the efficiency of your oven. Achieving a good char is key to enhancing the cauliflower’s natural sweetness for your Cauliflower Steaks with Chimichurri.
Step 5: While the cauliflower roasts, prepare the chimichurri. In a medium bowl, combine the finely chopped fresh flat-leaf parsley, finely chopped fresh oregano, and minced garlic. Ensure the herbs are very finely chopped for the best texture and flavor distribution in your chimichurri.
Step 6: Add the red wine vinegar, 1/2 cup of extra virgin olive oil, red pepper flakes (if using for a kick), and season generously with salt and black pepper. Stir all the ingredients well to combine. Taste and adjust seasonings as needed. If you have time, let the chimichurri sit for at least 10-15 minutes to allow the flavors to meld. You can even prepare the chimichurri a few hours ahead and store it in an airtight container in the refrigerator for an even richer flavor for your Cauliflower Steaks with Chimichurri.
Step 7: Once the cauliflower steaks are cooked to perfection, transfer them carefully to individual serving plates. Spoon a generous amount of the vibrant, fresh chimichurri over each steak. Serve immediately and savor every mouthwatering bite of your homemade Cauliflower Steaks with Chimichurri!
