- 1 bunch green garlic bulbs, tops sliced off
 - 1 tablespoon olive oil, or as needed
 - sea salt and ground black pepper to taste (optional)
 
- Preheat an outdoor grill for medium-high heat and lightly oil the grate.
 - Place garlic bulbs on large sheets of aluminum foil, up to 3 bulbs per sheet. Lightly drizzle olive oil over bulbs and season with salt and pepper. Wrap foil tightly around bulbs.
 - Place bulbs inside the preheated grill on the top rack away from the flames; cook until garlic cloves are butter-soft, about 30 minutes. Allow garlic bulbs to cool until easily handled. Squeeze garlic from bulb into a bowl and mash with a fork until spreadable.
