Drain and rinse the can of cannellini beans well to remove excess sodium.
In a food processor, add the beans, garlic, lemon juice, and lemon zest.
Blend until the mixture starts to become creamy.
With the food processor running, slowly pour in the olive oil and blend until smooth.
Season with sea salt, black pepper, and chopped parsley.
Blend just a little to combine the seasonings.
Transfer the dip to a serving dish, and add a drizzle of olive oil on top if desired.
