How to Make It
Preheat the oven to 450°. In a mini food processor, combine the garlic, cumin, coriander, 1 teaspoon of salt and 1/4 cup of the olive oil; puree until smooth.
Arrange the broccoli on 2 large rimmed baking sheets. Drizzle with the remaining 2 tablespoons of olive oil, season with salt and toss to coat. Roast for 5 minutes. Spoon the coriander oil over the broccoli, toss and roast for about 10 minutes longer, until just tender, shifting the baking sheets halfway through. Serve hot.
