How to Make It
Combine the panko and olive oil in a medium nonstick skillet over medium heat. Cook, stirring constantly, until the panko is toasted and golden brown, about 5 minutes. Transfer to a shallow container to cool and season with salt and pepper. Set aside for later.
Combine ¼ cup mayonnaise, eggs, mustard, and Old Bay in a large bowl and stir to combine. Add ½ cup of the toasted panko and the crab, using your spoon to break apart the meat.
Heat oven to 400°. Spoon ¾ teaspoon of toasted panko into the bottom of 1 ½ nonstick mini-muffin pans (about 32 cavities, total). Fill each cavity nearly to the top with crab mixture, then top each with another ¾ teaspoon toasted panko, spread in an even layer. Bake the bites until slightly puffed, about 8-10 minutes.
In a small bowl, combine ½ cup mayonnaise and lemon zest. Sprinkle with 1 tablespoon chives. Serve alongside crab cakes.
