Preheat your oven to 350°F (175°C).
In a mixing bowl, chop the drained marinated artichoke hearts into smaller pieces.
Add the chopped artichokes, cream cheese, mayonnaise, grated Parmigiano Reggiano cheese, diced jalapenos, salt, and black pepper to the bowl. Mix until well combined, adding a splash of water if needed.
Transfer the mixture to a baking dish and smooth the top.
Bake for about 20-25 minutes, or until hot and bubbly with a golden top.
Garnish with additional jalapeno slices and black pepper before serving warm with your favorite dippers.
