01 - Preheat oven to 350°F. Place salmon fillets on a parchment-lined baking sheet and season lightly with salt and pepper. Bake for 12–15 minutes until just cooked through. Let cool slightly, then flake into large pieces using a fork.
02 - In a large mixing bowl, combine the flaked salmon, panko breadcrumbs, beaten eggs, chopped parsley, lemon zest, lemon juice, minced garlic, diced red onion, Dijon mustard, salt, and black pepper. Gently fold until evenly incorporated, being careful not to overmix.
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. Carefully place the salmon cakes in the pan and cook for 3–4 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, finely minced garlic, lemon juice, Dijon mustard, salt, and pepper until smooth. Adjust seasoning to taste.
06 - Arrange the warm salmon cakes on a serving platter and top each with a generous dollop of lemon garlic aioli. Garnish with lemon wedges on the side.
