01 - Preheat oven to 350°F. Place salmon fillets on a parchment-lined baking sheet and season lightly with salt and pepper. Bake 12–15 minutes until just cooked through. Let cool slightly, then flake into large pieces with a fork.
02 - In a large bowl, combine flaked salmon, panko breadcrumbs, beaten eggs, chopped parsley, lemon zest, lemon juice, minced garlic, diced red onion, Dijon mustard, salt, and black pepper. Fold gently until just combined, being careful not to overwork the mixture.
03 - With damp hands to prevent sticking, shape the mixture 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 salmon cakes in the pan and cook 3–4 minutes per side until golden brown and heated through. Transfer to paper towels to drain.
05 - In a small bowl, whisk together mayonnaise, minced garlic, lemon juice, Dijon mustard, salt, and pepper. Adjust seasoning to taste.
06 - Serve the warm salmon cakes with a generous dollop of lemon garlic aioli and fresh lemon wedges on the side.
