Preheat the oven to 220 degrees Celsius (430 Fahrenheit).
Season the salmon fillet with half of the amount of salt and pepper.
Line a large baking tray with kitchen foil, and transfer the salmon fillet to it.
Bake for 15 minutes.
In the meantime, add the peeled and finely chopped onion and garlic to a large bowl together with the eggs, grated parmesan, parsley, dill, salt and pepper.
Mix well to get a uniform mixture, then set it aside.
Once the salmon is cooked, use 2 forks to flake it, then add it to the breadcrumb mixture and mix well.
Use your hands to shape patties, I got 11, but the amount will depend on their size.
Remove the kitchen foil from the tray, and drizzle the oil over the bottom of the tray.
Preheat the oil in the oven for 5 minutes, then arrange the patties onto the tray.
Flip the patties onto the other side so both sides are coated with the hot oil, then bake them for 20 minutes, flipping them again half the way through.
Serve hot!
