Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.
Prick the eggplants with a fork and place on the prepared baking sheet. Roast in the preheated oven for 30 minutes, or until the skin is lightly charred and eggplants are soft.
Remove from oven and let cool for 10 minutes. Peel off the charred skin, then roughly chop the eggplant.
In a food processor, combine tahini, lemon juice, garlic, olive oil, cumin and salt. Pulse until combined.
Add chopped eggplant and pulse until desired consistency is reached.
Transfer baba ganoush to a bowl. Taste and adjust seasonings if necessary. Serve with pita chips or fresh vegetables.
