Wrap the eggplant in aluminum foil and roast it in the preheated oven at 350°F (175°C) for about 30-35 minutes until it is soft.
If you poke the eggplant with a knife and it is soft, take it out of the oven and let it cool for about 10 minutes.
Now cut off the top of the eggplant and peel off the skin. You can throw away the peel and roughly dice the pulp.
Place all ingredients in a food processor and process the dip until creamy. The longer you process it, the creamier it will get. It shoud take about 3-4 minutes.
Taste the hummus again briefly and season to your taste.
