Preheat the oven to 400°F.
Place the carrots and whole garlic clove on a baking sheet. Drizzle with the olive oil, sprinkle with the salt, and toss to coat.
Roast for 45 minutes, or until the carrots are fork tender and starting to caramelize.
Place all the ingredients in a food processor and puree until smooth.
Note: You can thin this hummus by adding olive oil or hot water, 1 tablespoon at a time, until desired consistency is reached.
