Preheat the oven to 220 degrees Celsius. Toss the cauliflower florets with enough olive oil to coat them in a light, even layer of oil. Season with salt and pepper and arrange the florets in a single layer on a large, rimmed baking sheet. Roast for 30 to 35 minutes, tossing halfway through, until the florets are deeply golden brown at the edges.
