Ingredients
- 1 large head of cauliflower,trimmed and cut into ¾-inch thick steaks (about 4 steaks)
- 3 tbsp olive oil,divided
- Salt and freshly ground black pepper,to taste
- 1 cup roasted red peppers (jarred or homemade),drained
- ¼ cup almonds,toasted
- 2 garlic cloves,peeled
- 1 tbsp sherry vinegar or red wine vinegar
- ½ tsp smoked paprika
- ½ tsp red chili flakes (optional for heat)
- ¼ cup extra virgin olive oil (for Romesco sauce)
- Fresh parsley,chopped for garnish
Instructions
- Prepare the cauliflower steaks: Place the trimmed cauliflower head on a cutting board. Using a sharp knife, slice through the core to cut ¾-inch thick slices. Reserve any loose florets for roasting later.
- Preheat your oven to 425°F (220°C): Line a baking sheet with parchment paper or a light drizzle of olive oil to prevent sticking.
- Brush steaks with olive oil: Lightly coat both sides of each cauliflower steak with 2 tablespoons of olive oil; season generously with salt and pepper.
- Roast the cauliflower: Arrange steaks on the baking sheet and roast for about 15 minutes on the first side until golden brown.Flip carefully using a spatula, then roast an additional 10-15 minutes until edges are deeply caramelized and the centre is tender.
- While steaks roast, craft the Romesco sauce: In a food processor, combine roasted red peppers, toasted almonds, garlic, sherry vinegar, smoked paprika, and red chili flakes. Pulse until roughly chopped.
- Slowly drizzle in extra virgin olive oil: With the processor running, stream in ¼ cup olive oil until the sauce emulsifies to a vibrant, thick but pourable consistency. Taste and adjust seasoning with salt or vinegar if needed.
- Serve immediately: Place cauliflower steaks on warmed plates,spoon bold Romesco sauce atop each,and garnish with fresh parsley for a burst of color and herbal brightness.
Tips for Success
- uniform Steaks: consistency in thickness ensures even roasting.For thinner steaks, reduce cooking time to avoid drying.
- Prevent breakage: Use a very sharp knife and cut slowly; a serrated knife may snag the core.
- Extra Crunch: Don’t skip the flip and roast the second side well to develop crispy, golden crusts.
- Make-Ahead Romesco: The sauce improves when rested overnight in the fridge. Bring to room temperature before serving.
- Loose florets: Toss with olive oil and roast alongside steaks for a complementary texture and flavor burst.
Serving Suggestions
To truly elevate the plate, serve your roasted cauliflower steaks alongside a light grain like quinoa or farro for nutty contrast. A crisp,citrusy salad or a dollop of cooling Greek yogurt balances Romesco’s smoky heat,while toasted pine nuts and microgreens add visual and textural allure. Drizzle a touch of balsamic glaze for an elegant finishing touch. For a vibrant vegan option, garnish with toasted pumpkin seeds and freshly squeezed lemon zest.
