These roasted cauliflower steaks with olive relish and tomato sauce offer a sophisticated take on plant-based dining. By caramelising the cauliflower in a frying pan before roasting, you achieve a deep, nutty flavour that pairs beautifully with the punchy, Mediterranean-inspired olive and sun-dried tomato relish. The dish is brought together by a silky, roasted tomato and garlic purée that adds a rich, savoury depth to every bite.
This vibrant vegan recipe is an excellent choice for a healthy midweek meal or a light weekend dinner. The combination of textures—from the tender cauliflower to the bite of the fresh relish—makes it a satisfying main course that looks wonderful on the plate. Serve it warm from the oven or at room temperature for a delicious, vegetable-forward feast.

Ingredients for Cauliflower Steaks with Olive Relish and Tomato Sauce
1 large head of cauliflower
1/2 cup pitted oil-packed black olives, finely chopped
3 sun-dried tomatoes, thinly sliced
50ml olive oil, divided, plus more
2 tablespoons chopped flat-leaf parsley
1 teaspoon fresh lemon juice
Kosher salt and freshly ground black pepper
3 garlic cloves
2 plum tomatoes, cored, quartered
How to make Cauliflower Steaks with Olive Relish and Tomato Sauce
Remove leaves and trim stem end of cauliflower, leaving core intact. Place cauliflower core side down on a work surface. Using a large knife, slice cauliflower into four 1/2" "steaks" from centre of cauliflower (some florets will break loose; reserve). Finely chop enough loose florets to measure 1/2 cup. Transfer chopped florets to a small bowl and mix with olives, sun-dried tomatoes, 1 tablespoon oil, parsley, and lemon juice. Season relish with salt and pepper.
Preheat oven to 400°. Heat 1 tablespoon olive oil in a large heavy ovenproof skillet over medium-high heat. Working in 2 batches, cook cauliflower steaks until golden brown, about 2 minutes per side, adding tablespoon oil to pan between batches. Transfer steaks to a large rimmed baking sheet. Reserve skillet. Roast cauliflower until tender, about 15 minutes.
Meanwhile, return skillet to medium-high heat and add garlic cloves and tomatoes, one cut side down. Cook until tomatoes are browned; turn tomatoes over and transfer skillet to oven with cauliflower. Roast garlic and tomatoes until tender, about 12 minutes.
Transfer garlic, tomatoes, and 1/2 tablespoons oil to a blender; purée until smooth. Season with salt and pepper. Divide tomato sauce among plates. Place 1 cauliflower steak on each plate; spoon relish over. Serve warm or at room temperature.
