Braising and putting enough garlic on broccoli rabe makes for a tasty side dish for Italian meals.
In a large pot, heat oil over medium-high. Add garlic and cook until fragrant, 30 seconds. Add broccoli rabe, broth, and red-pepper flakes and season with salt. Bring to a boil. Cover, reduce heat to medium-low, and cook until crisp-tender, 3 to 5 minutes.
