Gather all ingredients and set up a high-speed blender or food processor.
Add drained chickpeas and 2 tablespoons of the reserved chickpea liquid to the blender.
Throw in garlic cloves, ground cumin, salt, lemon juice, and olive oil.
Blend until smooth, scraping down the sides as needed. If too thick, add a bit more reserved liquid.
Transfer the hummus to a serving bowl, drizzle with olive oil, and sprinkle with extra cumin or paprika if desired.
Serve chilled or at room temperature with pita bread, crackers, or fresh vegetables.
