Remove crab meat from its container and drain thoroughly. This will help to ensure your dip isn’t watery. Set aside.
In a stand mixer or large bowl, cream together the cream cheese, sour cream and mayonnaise until smooth.
Squeeze in the fresh lemon juice. then blend in the Worcestershire sauce, Old Bay seasoning, black pepper, garlic, onions, and scallions.
By hand, gently stir in the grated cheese.
Gently break apart the crab meat and fold into the mixture. You’ll want to keep the pieces intact as much as possible.
Spoon the prepared dip into your baking dish, lightly sprayed with cooking spray, and sprinkle with the reserved scallions.Bake for approximately 20 minutes until the dip is bubbly and lightly browned on top (you can always set the broiler on low for a few minutes to help with the browning).
