Preheat your oven to 350°F (175°C). This ensures that when your crab dip is ready, it will bake evenly and come out warm and bubbly.
In a large mixing bowl, combine the room temperature cream cheese, mayonnaise, and sour cream. Use a spatula to mix until the mixture is smooth and creamy. This will be the rich base of your crab dip.
Next, add the minced garlic, chopped green onion, Old Bay seasoning, salt, Worcestershire sauce, and lemon juice to the cream cheese mixture. Stir until all ingredients are well incorporated. This step is crucial as it builds the flavor profile of your dip.
Gently fold in 1 cup of the freshly shredded cheddar cheese and the fresh jumbo lump crab meat. Be careful not to break up the crab too much; you want to maintain those beautiful chunks!
Spoon the crab dip mixture into your prepared baking dish. Smooth the top with the spatula, and then sprinkle the remaining cheddar cheese on top. This will create a delicious, cheesy crust when baked.
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the dip is hot and bubbly, and the cheese is melted and golden. Keep an eye on it to avoid burning!
Once your crab dip is ready, remove it from the oven and let it cool for a few minutes. Serve it warm with sourdough bread, crackers, tortilla chips, or fresh veggies for dipping. Enjoy every creamy, cheesy bite!
