Preheat the oven to 350F. Prepare a 8x8 (2 quart) baking dish with cooking spray.
In a large bowl, with a hand mixer, whip the cream cheese until smooth. Stir in the mayonnaise and the sour cream until mixed through.
Stir in the chopped crab, lemon juice, half the green onions, soy sauce, and mustard. Taste and adjust seasoning with salt and pepper if needed.
Spread into the baking dish. Top with shredded mozzarella cheese.
Bake at 350F for 20 minutes or until bubbly and the cheese is melted.
Remove, sprinkle with sesame seeds and remaining green onions. Enjoy with wonton chips or your favorite crackers.
Homemade Wonton Chips
To make the wonton chips, I cut the wonton wrappers in half in triangles. You can also use egg roll wrappers and but into squares and then in triangles or strips.
Preheat the air fryer to 370F.
Add the sections in a single layer (with room in between them), spray with cooking spray.
Air fry for 2-3 minutes or until they start to brown on the edges.
Flip or shake the basket gently, and continue to air fry until a light golden brown. Just another minute or two, they burn quickly!
Remove and let cool. Continue in batches until they are all done.
Notes
Soften cream cheese to room temperature before mixing. Cold cream cheese stays lumpy no matter how much you stir.
Using real crab instead of imitation crab for more flavor. Imitation crab is milder, but it has the bright color and is more budget-friendly.
Use Kewpie mayo if you can find it. It's much richer and adds more flavor.
Chinese mustard adds essential tangy spicy kick that regular mustard can't match. This is what makes it taste like real crab rangoon.
Dividing the green onions keeps half fresh and bright for topping. Baked green onions get dark and lose their color.
Watch the wonton chips closely in the air fryer. They go from perfect to burned in seconds.
Make wonton chips in batches. Overcrowding prevents them from crisping evenly.
Serve the dip hot and bubbly straight from the oven when the cheese is melted and gooey.
