First things first, let's start by prepping the salmon filets! Rinse the salmon well. This is optional, but I personally prefer to rinse all the residue off. Let the water drain off and then pat it dry using a paper towel.
Place the salmon skin-side down in a roasting pan. Next, mix all ingredients together (yes, right on top of the fish) and spread the mixture over the entire salmon. It's as simple as that!
You can also just mix it separately in a small bowl and transfer it if you wish, but this way ensures all of the ingredients make it on the fish. And it even saves you the extra dish to wash!
Finally, slice the onion and lemon and lay the slices out throughout the salmon. I've also added some chopped fresh parsley on top but that's absolutely optional.
Bake the salmon for 45 min at 375 F in a preheated oven. Once it's done, remove the salmon from the oven. Let it cool for 10 minutes before transferring it onto a platter or serve on the baking pan.
This dish disappears from the dinner table quickly because it's so delicious and my family absolutely loves it! But if you have some leftover baked salmon left, you can refrigerate it for up to 3 days.
