In a large bowl, toss broccoli florets with the extra virgin olive oil, sea salt, pepper, and garlic. Spread the broccoli out in an even layer on a baking sheet.
Bake in the preheated oven until florets are tender enough to pierce the stems with a fork, 15 to 20 minutes. Remove and transfer to a serving platter. Squeeze lemon juice liberally over the broccoli before serving for a refreshing, tangy finish.
