1 teaspoon salt
2 bunches broccoli (about 3 pounds), stems removed, cut into florets
6 thick-sliced bacon strips, chopped
2 tablespoons olive oil
6 to 8 garlic cloves, thinly sliced
1/2 teaspoon crushed red pepper flakes
1/4 cup shredded Parmesan cheese
Fill a 6-qt. stockpot two-thirds full with water; add salt and bring to a boil over high heat. In batches, add broccoli and cook until broccoli turns bright green, 2-3 minutes; remove with a slotted spoon.
In a large skillet, cook bacon over medium heat until crisp, stirring occasionally. Remove with a slotted spoon; drain on paper towels. Discard drippings, reserving 1 tablespoon in pan.
Add oil to drippings; heat over medium heat. Add garlic and pepper flakes; cook and stir until garlic is fragrant, 2-3 minutes (do not allow to brown). Add broccoli; cook until broccoli is tender, stirring occasionally. Stir in bacon; sprinkle with cheese.
