Preheat oven to 425°F. Arrange salmon skin side down on baking sheet and brush lightly with olive oil. Sprinkle with salt and pepper, then roast for 10-15 minutes until just done. Flake with a fork and cool.
1 pound fresh salmon*, 2 Tablespoons olive oil
Meanwhile, heat olive oil in a large skillet over medium heat. Add onion, celery, and bell pepper. Cook for 7-9 minutes until softened. Remove from heat and set aside.
½ medium red onion, 2 celery stalks, ½ red bell pepper
In a large bowl, combine the cooked, flaked salmon, sauteed veggies, breadcrumbs, mayonnaise, mustard, eggs, parsley, dill, chives, Worcestershire sauce, Old Bay seasoning, and salt & pepper. Stir well to combine. Use a large cookie scoop to scoop ¼ to ⅓ cup size mounds and shape into patties.

Heat remaining olive oil and butter in the same skillet used to cook the vegetables over medium heat. Add the salmon cakes in batches, frying for 2-3 minutes on each side, until browned. Drain on paper towels and keep warm in a preheated 250°F oven while frying the remaining salmon cakes. Serve hot with aioli.
1 Tablespoon salted butter
To make the aioli, whisk together the mayonnaise, lemon zest and juice, garlic, salt, and pepper. Refrigerate until ready to use.
