Preheat the oven to 400℉. Chop potatoes in half or quarters and add to a large sheet pan. Toss with olive oil, salt and pepper. Bake for 25 minutes, flipping with a metal spatula about half way through.
Meanwhile, mince 3 cloves of garlic. Add about 1 clove to the butter for the potatoes. The other 2 can be minced with the almonds. Add the garlic, almonds, panko, Parmesan cheese and olive oil to a bowl and mix.
Season the salmon with most of the salt and pepper, the rest can be added to the almond mixture.
When the potatoes are par-roasted for 25 minutes, flip them and move to opposite corners of the pan and lay the salmon filet diagonally down the middle, skin side down. Be careful with the hot pan! Spoon the topping over the salmon, lightly pressing it to the flesh to adhere.
Return to the oven to bake the salmon and finish crisping the potatoes, about 20 to 25 minutes.
To finish the potatoes, melt the butter with the minced garlic in the microwave and add chives. Spoon over the potatoes and toss with a spatula.
Let the salmon rest for 5 minutes before serving. Garnish everything with more fresh chives and a squeeze of lemon juice.
Use a fish spatula to pull away pieces of salmon, leaving the skin behind on the pan. Serve with the crispy potatoes, more lemon wedges, and a green salad.
