Preheat oven to 350°F.
Mix softened cream cheese, mayonnaise and artichokes in medium sized mixing bowl until cream cheese is blended thoroughly.
Add garlic, lemon zest, sea salt, black pepper, Parmesan cheese and green onions. Mix again until well blended.
Add crab claw meat and mix gently, just until blended. You don't want to break up the chunks of crab.
Spread into a well seasoned cast iron skillet, or any other baking dish (spray with nonstick cooking spray before adding dip mixture). Top with remaining ¼ cup Parmesan cheese.
Bake for 30 minutes until thoroughly heated and bubbly.
Place skillet or baking dish on top rack and turn on broiler to high. Watch carefully until top is nicely browned. This took 3 minutes in my oven, but again, watch carefully as it can be faster in your oven and may burn.
Remove from oven and top with additional green onions and diced red bell pepper. Serve with baguette slices (fresh or toasted) or tortilla chips.
