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 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. Fold gently until evenly incorporated, 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. Carefully add the salmon cakes 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, minced garlic, lemon juice, Dijon mustard, salt, and pepper until smooth. Adjust seasoning to your liking.
06 - Arrange the warm salmon cakes on a serving platter with a generous dollop of lemon garlic aioli and fresh lemon wedges alongside.
