Roasted cauliflower steaks are a visually striking and delicious way to showcase this nutrient-packed vegetable. Thick slices of cauliflower are brushed with a savory blend of olive oil, lemon juice, garlic, turmeric, and spices, then oven-roasted until tender and golden-brown — a flavorful side dish or plant-forward main that’s rich in fiber and antioxidants.
