Preheat your oven to 375 degrees Fahrenheit and slice the root end off the bulb of garlic.
Place the garlic on a parchment lined baking sheet, cut end up, and drizzle with the olive oil.
Roast the garlic for about 25-30 minutes or until it's soft and slightly browned.
Remove the garlic from the oven and let it cool slightly before squeezing the roasted cloves out of their skins and into the bowl of your food processor.
Add the chickpeas, the tahini, lemon juice and sea salt, and blend on high speed until the mixture is creamy and smooth.
While the food processor is running, drizzle in the olive oil until the hummus becomes even more creamy and pale in colour.
Serve immediately with your favourite veggies, pitas, crackers or chips!
