How to Make Cauliflower Steaks with Romesco Sauce and Herbs

Prep the Cauliflower: Slice a firm cauliflower head into ¾-inch-thick steaks, removing loose florets to ensure each piece holds together during cooking. Pat dry with paper towels for crisp edges.
Season the Steaks: Brush both sides with olive oil and generously season with salt and pepper, ensuring an even coating so they caramelize beautifully without sticking in the pan.
Sear the Steaks: Heat a skillet over medium-high until shimmering, then cook each steak 4–5 minutes per side, pressing gently, until deep golden brown and tender-crisp.
Rest Briefly: Transfer steaks to a warm plate and let rest for 2 minutes, allowing the cauliflower to relax and juices to redistribute for maximum flavor.

For the Romesco Sauce:

Blend the Sauce: In a blender, puree roasted red peppers, tomatoes, toasted almonds, garlic, smoked paprika, and red wine vinegar until smooth, creamy, and vibrant in color.
Finish and Season: With blender running, drizzle in extra virgin olive oil until velvety, scrape down the sides, then taste and adjust salt or vinegar for balanced brightness.
Serve and Garnish: Arrange cauliflower steaks on plates, spoon Romesco sauce generously over each, then scatter flat-leaf parsley and fresh thyme leaves for a fragrant, colorful finish.

Optional: Add a sprinkle of toasted pine nuts for extra crunch.

Zesty Citrus: Squeeze fresh lemon or lime juice over the plated steaks before serving to brighten the flavors and add a refreshing zing. The citrus offsets the richness of the sauce perfectly.
Veggie Medley: Add sliced bell peppers or zucchini to the pan with the cauliflower steaks for a colorful and nutrient-rich side that complements the Romesco sauce beautifully. This adds vibrant textures and even more deliciousness to the meal.

Cauliflower Steaks with Romesco Sauce and Herbs Recipe FAQs

How do I choose the best cauliflower for steaks?
Look for a firm, white head with tightly packed florets and no dark spots or bruises. A fresh cauliflower will feel heavy and dense, which helps the steaks hold together during cooking.

Can I store leftover cauliflower steaks with the Romesco sauce?
It’s best to store the steaks and Romesco sauce separately. Keep cauliflower steaks in an airtight container in the fridge for up to 3 days. Store the Romesco sauce in a sealed jar, which preserves its vibrant flavor for about the same time.

Is it possible to freeze cauliflower steaks with Romesco sauce?
I recommend freezing the cauliflower steaks alone. Wrap each steak tightly in plastic wrap, place them in a freezer-safe bag, and freeze for up to 3 months. When ready to eat, thaw in the fridge overnight and reheat gently in a skillet with a splash of olive oil. Avoid freezing the sauce as it can separate and lose texture.

What if my cauliflower steaks fall apart while cooking?
If your steaks are breaking apart, it might be because the slices are too thin or the cauliflower is not firm enough. Make sure to cut ¾-inch-thick steaks and pat them dry before seasoning. Use a hot skillet and press gently without flipping too soon to help them hold their shape and develop a crisp, golden crust.

Are Cauliflower Steaks with Romesco Sauce and Herbs pet-safe?
Cauliflower itself is generally safe for dogs in small amounts, but the Romesco sauce contains ingredients like garlic and vinegar, which are toxic to pets. Keep this dish exclusively for humans and offer your furry friends pet-safe treats instead!
