Preheat the oven to 400ºF. Line a baking sheet with parchment paper. Spread the frozen florets out over the baking sheet . Drizzle the olive oil over the florets, then sprinkle the Montreal steak seasoning over top. Toss the florets in the oil and seasoning until everything is evenly distributed . Transfer the baking sheet to the oven and roast for 20 minutes. Take the baking sheet out and use a spatula to stir the broccoli and redistribute the oil and spices. Return the baking sheet to the oven and roast for another 10 minutes, or until the broccoli develops the amount of brownness desired. Serve hot.
