Preheat the oven to 375°F. In a skillet over medium heat, melt one tablespoon of butter, then add the softened cream cheese and cheddar cubes. Stir until melted.
Add three tablespoons of heavy cream and soy sauce to the cheese mixture and stir until completely incorporated.
Shred the crab meat, then add it to the cheese mixture. Stir well to combine, then add a dash of pepper and one of the chopped green onions. Remove the pan from the heat.
In a small bowl, melt the remaining 3 tablespoons of butter. Stir the melted butter into the panko bread crumbs along with the ¼ cup of Parmesan cheese.
Spoon the crab and cheese mixture into an oven-safe bowl or pan (I used two ramekins). Top the crab and cheese with panko, then bake at 375°F for 20 minutes or until the panko crust is golden brown.
While the dip is baking, fill a large pot with a few inches of vegetable oil, or use a deep fryer, and heat to 325°F. Cut the wonton wrappers in half diagonally to make triangles, then fry in batches until golden brown. Remove from the oil with a slotted spoon and place on a paper towel to dry. Sprinkle with coarse sea salt.
Let the dip cool for a few minutes after removing it from the oven. Top the dip with sriracha for a spicy flair and garnish with the remaining chopped green onion. Serve alongside the wonton chips and enjoy!
