Preheat your oven to 425°F. Lightly coat a 9-inch baking dish or cast iron skillet with nonstick spray.
In a large bowl, mix together the cream cheese, mayonnaise, and sour cream. Stir in 1/2 cup of the Monterey Jack cheese, Parmesan cheese, scallions, Worcestershire sauce, soy sauce, orange juice, Sriracha, and garlic powder. Season with a little salt and pepper to taste. Gently fold in the lump crab meat.
Spread the crab mixture into the prepared baking dish and sprinkle the remaining 1/2 cup of Monterey Jack cheese on top.
Bake in the oven until the dip is bubbly and golden, about 20-25 minutes.
Serve immediately with toasted wontons, sourdough chips, or fresh veggie sticks.
