Preheat your oven to 350°. Lightly grease a 8X8 or 9X9 baking dish or a pie plate.
In a large bowl, combine cream cheese, sour cream, Parmesan cheese, Monterey Jack, Worcestershire sauce, garlic powder and paprika. Mix until evenly combined. Taste test and add more seasonings if desired.
Fold in the crab and green onions until combined.
Spoon the dip into the prepared baking dish, ensuring it is level. Bake for 20 to 25 minutes, until the dip is nice and golden on top.
Garnish with more green onions and drizzle with Sriracha, if desired.
