Preheat the oven to 350°F/180°C. On a baking sheet, oil the potatoes and sprinkle with salt and pepper. Bake for one hour and twenty minutes. An additional 15 minutes per potato is needed if you’re making more.
Meanwhile, cook the chopped salmon with the minced garlic, ginger, seasoning, and olive oil. Stir until fried. Set aside.
Once the potatoes are baked, cut them in half and scoop out the insides while still warm, and transfer to a bowl.
In the bowl with the scooped out potato, add the cheese, parsley, salmon (leave a little to sprinkle on top), softened butter, milk, salt, and pepper. Mix well. Scoop the potato mixture back into the hollowed-out potatoes and top with gouda cheese and remaining salmon bits.
Bake an additional 15 minutes until the cheese is melted. Serve warm with a sprinkle of chives!
