In a high-speed blender, combine the cooked chickpeas, 3 cups (720ml) of their cooking liquid, roasted garlic, and extra virgin olive oil.
Season generously with salt and pepper.
Blend on high for 1-2 minutes, scraping down the sides as needed, until the mixture is completely smooth, light, and airy. If the fondue is too thick, add more cooking liquid a tablespoon at a time until it reaches the consistency of a thick, pourable soup.
Pour the purée into a saucepan and warm over medium heat.
Stir constantly until heated through, ensuring it doesn't come to a boil.
Remove the pot from the heat and stir in the fresh lemon juice.
Taste and adjust the seasoning with more salt, pepper, or lemon juice as needed.
Transfer to a fondue pot or a pre-warmed serving bowl.
Garnish with a sprinkle of fresh parsley and serve immediately with your favorite dippers.
