Preheat oven to 400° F degrees.
Wrap eggplant in aluminum foil and roast for 45-60 minutes until the eggplant is soft when poked with a fork or knife. Unwrap the eggplant and allow it to cool for 10 minutes.
When the eggplant is cool to the touch, cut off the top and peel off the skin. Discard the skin, keeping only the flesh of the eggplant.
Place the flesh of the eggplant in a food processor or blender. Add the lemon juice, tahini, garlic cloves and salt. Blend for 1 minute until the mixture is smooth and creamy.
Alternatively, you can blend the lemon juice, tahini and garlic first, and then add the eggplant. Either way works.
Garnish with parsley and olive oil, if desired. Enjoy with pita bread, crudité or crackers.
