Pre-heat Air Fryer at 370°F (188°C). Set at 10 minutes.
Smear butter on both sides of the thick sourdough bread.
Place bread onto Air Fryer tray and slowly insert tray into the middle cooking chamber, near the rotisserie catch. Air Fry thick sourdough bread slices for 2 minutes on each side or until slightly golden. Remove slightly golden bread slices from the Air Fryer.
Add crab meat, dill, parsley, salt, black pepper, garlic powder, paprika, lemon zest, and mayonnaise to a large bowl.
Mix ingredients until well combined.
Spread crab mixture over lightly toasted bread slices. Sprinkle half the grated mozzarella. Top with 1 slice of tomato and the rest of the grated mozzarella cheese.
Return the Air Fryer tray with crab-filled bread slices. Cook for 4 to 5 minutes until cheese is melted and slightly golden.
Garnish with the remaining fresh parsley. Serve immediately.
Notes
This Air Fryer recipe uses an Instant Vortex Plus Air Fryer Oven. Not all Air Fryers cook the same way. It’s best to keep watch during your initial tests after purchasing.While filling the bread slices with the crab mixture, close the door of the Air Fryer Oven. If you will not close the door, the Air Fryer temperature might change. It’s best to close the door and manually adjust the timer as needed.Slightly toasting the thick sourdough slices will provide a sturdy base for the crab mixture. It would be easier to hold them, should you prefer. Freshly grated mozzarella cheese was used in this recipe.Only use mild blocks of cheeses to avoid overpowering the delicate crab.Fresh dill is light, bright, and refreshing. It is recommended to use fresh dill as dried dill or dill weed can overpower the delicate crab meat.Budget-friendly canned crab meat is used but lump crab (canned or fresh) would be recommended if you prefer to see large pieces of crab and don’t mind the hefty price.
