Add the avocados, red onion, cilantro, jalapeño, garlic, lime juice, and sea salt to a medium-sized mixing bowl.
Using a fork, mash everything together until the avocados are creamy but still slightly chunky, and the ingredients are evenly combined.
Fold in 1/2 cup of the pomegranate seeds, stirring gently so they’re dispersed throughout the guacamole without crushing them. Transfer the mixture to a serving bowl.
Scatter the remaining 1/4 cup of pomegranate seeds over the top and finish with an extra sprinkle of chopped cilantro, creating a festive red-and-green contrast that’s ready for the table.
