Instructions

  1. Step 1: Remove the leaves and trim the stem of 1 large cauliflower head. Slice it into 3/4-inch thick 'steaks' carefully so they hold together.
  2. Step 2: In a small bowl, combine 2 tbsp harissa paste, 2 tbsp olive oil, 1 tsp smoked paprika, 1/2 tsp ground cumin, 3/4 tsp salt, and 1/2 tsp black pepper into a smooth marinade.
  3. Step 3: Brush both sides of each cauliflower steak generously with the harissa marinade, allowing some to drip into the crevices.
  4. Step 4: Preheat the air fryer to 380°F. Place the cauliflower steaks in a single layer inside the basket and air fry for 12 minutes, flipping halfway through, until edges are golden and the center is tender.
  5. Step 5: Serve immediately with fresh lemon wedges to squeeze over for brightness.
