Preheat your oven to 350°F.
This will be the perfect temperature for baking the dip until it’s hot and bubbly.
In a large mixing bowl, combine cream cheese, Monterey Jack, Parmesan, and mayonnaise.
Mix until smooth and well-blended.
Add chopped onion, minced garlic, Worcestershire sauce, hot sauce, Cajun seasoning, and lemon juice.
Stir everything together to create a flavorful base.
Fold in the shrimp and crab meat carefully, making sure it’s evenly distributed in the mixture.
This ensures every bite has plenty of seafood goodness!
Transfer the mixture into a baking dish.
Bake in the preheated oven for 25-30 minutes, or until the top is golden and the seafood is cooked through.
