Place the broccoli in a large bowl. Spray thoroughly with pan spray. Sprinkle the steak seasoning, chili powder, garlic powder, salt, and pepper over the vegetables. Stir the broccoli to coat with oil and seasonings. Spread broccoli onto a shallow baking pan.
Bake in the preheated oven until the vegetables are tender and beginning to brown, 15 to 20 minutes.
