Ingredients for Sheet Pan Roasted Cauliflower Steaks with Romesco Sauce

Instructions

Preheat oven to 425°F (220°C). Line a large sheet pan with parchment paper or lightly grease it.
Remove green leaves from the cauliflower, keeping the core intact. Slice the cauliflower crosswise into 3/4-inch thick 'steaks'—about 4 steaks plus some florets.
Place cauliflower steaks and loose florets on the sheet pan. Brush both sides with 2 tablespoons olive oil, and season generously with salt and freshly ground black pepper.
Roast for 25-30 minutes, flipping halfway through, until stakes are golden brown and tender.
While roasting, prepare the romesco sauce: in a blender or food processor, combine roasted red bell pepper, roasted tomato, toasted almonds, minced garlic, sherry vinegar, smoked paprika, cayenne pepper (if using), tomato paste, and salt and pepper.
Blend while slowly drizzling in 1/4 cup olive oil until smooth, retaining a slightly textured consistency. Adjust seasoning to taste.
Remove roasted cauliflower from oven and transfer to a serving platter.
Spoon the romesco sauce generously over each cauliflower steak.
Garnish with chopped fresh parsley and serve warm.
Optional: pair with a fresh side salad or crusty gluten-free bread for a complete, satisfying meal.
