Preheat the oven to 400°F. Slice eggplants in small pieces. In a bowl, toss eggplant slices with salt and 1 tbsp of olive oil. Place it on a baking sheet along with the unpeeled garlic. Roast until tender, 30-40 minutes. Remove the eggplant and garlic from the oven and allow to cool for 10 minutes before removing the garlic peel.
Place the eggplant, garlic, tahini and lemon juice in a food processor and process until fairly smooth. Add the olive oil and salt and process it briefly. Scrape the mixture into a bowl, taste and add more lemon juice or salt to taste.
With the back of a spoon, make a swirl in the top of the baba ganoush, drizzle olive oil in the swirl grooves, and sprinkle with paprika.
