Preheat the oven: Preheat your oven to 375°F and lightly grease a small baking dish or oven-safe skillet.
Make the dip: Add whipped cream cheese and sour cream to a bowl. Fold in the Parmesan cheese, sharp cheddar, fresh jalapeño, jarred jalapeños, pomegranate arils, scallions, and lime juice. Season with salt and pepper and mix until everything is evenly incorporated.
Bake the dip: Transfer the mixture to your prepared baking dish and spread into an even layer. Bake uncovered for 20–25 minutes, or until the cheese is melted, the edges are bubbling, and the top is lightly golden.
Make the pomegranate relish: While the dip bakes, combine the pomegranate arils, chopped cilantro, honey, lime juice, and olive oil in a small bowl. Season with salt and pepper, then gently toss to combine. Set aside until ready to serve.
Assemble and serve: Remove the dip from the oven and let cool for 3–5 minutes. Spoon the honey lime pomegranate salsa generously over the top, spreading it evenly so you get a little in every bite.
Serve: Serve warm with chips or veggies for dipping.
