Spray a 9x9 inch baking pan with cooking spray and set aside.
In a small pan add olive oil and green onions. Sauté over medium-high heat until the onions are softened and then remove them from the heat.
Beat together green onions, cream cheese, mayonnaise, sour cream, ⅓ cup parmesan cheese, chives, dill, lemon juice, and salt until well combined and creamy. Fold in crab meat.
Spread crab mixture evenly into prepared baking dish and sprinkle with remaining ⅓ cup Parmesan cheese.
Bake for 20-30 minutes until lightly brown and cheese is melted on top.
