Pre-heat the oven to 400F. Line a baking sheet with parchment paper, foil, or a silicone baking mat. Place the salmon filets on the baking sheet.
In a small bowl mix together the lemon zest and juice, garlic powder, avocado oil butter, and parsley.
Using a basting brush, coat one side of the salmon with the lemon mixture and then season with salt and pepper. Repeat for the other side.
Bake in the 400F oven for 8-10 minutes, depending on the thickness of your salmon. If the salmon has skin, bake skin side down.
Remove from the oven and serve.
