Start by preheating your oven to 375°F (190°C). I pat the salmon dry with paper towels, then carefully slice a pocket lengthwise into each fillet. This pocket is where all the creamy crab filling will go, so take your time and avoid cutting all the way through.
In a mixing bowl, I gently combine the crab meat, softened cream cheese, mayonnaise, garlic, lemon zest, lemon juice, Dijon mustard, paprika, salt, and pepper. I mix just until combined, keeping the crab chunky so the filling feels luxurious and not mushy.
Next, I spoon the crab mixture evenly into each salmon pocket. I don’t overfill, but I make sure each fillet looks nicely plump. Any extra filling can be spread lightly on top.
I mix melted butter with a little extra lemon juice and brush it generously over the stuffed salmon. This step keeps the fish moist and adds that rich, glossy finish once baked.
I place the salmon in a baking dish and bake it uncovered for 18–22 minutes. The salmon should flake easily with a fork, and the filling should be hot and slightly golden on top.
After baking, I let the salmon rest for a couple of minutes. Then I sprinkle fresh parsley on top for color and a fresh pop of flavor before serving.
