Preheat the oven to 375 degrees F. Slice the tops of the garlic and set on a piece of foil on a cookie sheet.
Drizzle garlic with olive oil and fold the foil over, sealing the ends. Roast at 375 degrees F for about 45 minutes, until cloves are soft and golden. Let cool, then squeeze out cloves and set aside.
Make the dip:
Rinse and drain the beans. Place in a food processor with roasted garlic cloves, olive oil, lemon juice, dill, and salt.
Puree until fairly smooth. Add more oil if it seems too thick. Add more salt or dill as desired.
Serve with crackers or tortilla chips.
