A decadent, creamy crab and cheese spread with a golden, crunchy topping, made quickly in the air fryer. Perfect for parties, potlucks, or cozy gatherings, this easy appetizer is a crowd-pleaser with bold flavor and comforting texture.
For gluten-free, use GF panko or omit topping. For keto, skip panko and serve with veggies. Use room temperature dairy for best texture. Can be made ahead (minus topping) and air fried before serving. Watch air fryer closely to avoid overcooking. Substitute Cajun seasoning for a spicy twist, or use plant-based dairy for a dairy-free version.
