01 - Preheat oven to 350°F. Place salmon fillets on a parchment-lined baking sheet and season lightly with salt and pepper. Bake for 12 to 15 minutes until just cooked through. Let cool slightly, then flake into large pieces using a fork.
02 - In a large bowl, combine the flaked salmon, panko breadcrumbs, beaten eggs, chopped parsley, lemon zest, lemon juice, minced garlic, diced red onion, Dijon mustard, kosher salt, and black pepper. Gently fold until just evenly combined, being careful not to overwork the mixture.
03 - With damp hands, divide the mixture and shape into 8 small cakes or 4 larger patties, pressing firmly so they hold together.
04 - Heat olive oil in a large non-stick skillet over medium heat. Place the salmon cakes in the pan and cook for 3 to 4 minutes per side until golden brown and heated through. Transfer to a plate lined with paper towels to drain.
05 - In a small bowl, whisk together the mayonnaise, minced garlic, lemon juice, and Dijon mustard. Season with salt and pepper to taste.
06 - Arrange the warm salmon cakes on a platter and serve with a generous dollop of lemon garlic aioli alongside fresh lemon wedges.
