Preheat the oven to 400 degrees F (200 degrees C).
Toss broccoli florets with extra virgin olive oil, sea salt, pepper, and garlic in a large bowl. 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 broccoli before serving for a refreshing, tangy finish.
