Preheat oven to 350° Fahrenheit (175° C).
In a medium bowl, combine the cream cheese, onion, mayonnaise, crabmeat, garlic powder, salt, and ½ of shredded cheese. Stir until very well combined.
Spread into a small 6-inch cast-iron skillet or 1 quart baking dish. Top with other ½ cup cheese.
Bake for 20 minutes in the preheated oven or until bubbly.
Turn broiler on and broil until cheese on top is browned in spots.
Remove from oven and let sit 5-10 minutes before serving. The dip will be very hot.
To make crostini: Cut a baguette into 1/2" slices. Preheat oven to 350º and arrange slices in a single layer on a baking sheet. Sprinkle with salt and bake about 15 minutes, or until tops are just beginning to turn golden brown. Slices should feel very firm but not totally crisp yet. Let cool 10 minutes.
For a gluten free appetizer, be sure to use gluten free bread, crackers, or chips.
