In a large skillet over medium heat, pour in just enough olive oil to coat the bottom of the skillet, and heat until olive oil is shimmering. Add garlic and stir, approximately 30 seconds. Add broccoli in an even layer and cook, without moving, until the bottom of the broccoli is crispy and golden (about 3 minutes). Flip and cook until crispy on other side, (another 2 minutes).
11 Remove broccoli and garlic from skillet and transfer broccoli to a paper towel-lined plate to drain. If necessary, work in batches to cook remaining broccoli.
12 Squeeze lemon juice over broccoli and sprinkle with Parmesan, flaky sea salt, and pepper.
13 Serve with red pepper flakes, ranch and extra parmesan on the side.
