Preheat Oven to 400℉. Place Salmon on Baking Sheet, skin side down, parchment paper optional for easier cleanup.
Add spices to a bowl and stir to combine. Evenly distribute seasoning over the tops of the fish filets.
Top each filet with a pat of butter (about 1½ tsp for each fish).
Drizzle chili oil over the fish (about 2 tbsp in total).
Bake in the oven for 15-17 minutes, depending upon desired doneness. If meal prepping, reduce bake time by 1-2 minutes to allow for reheating without overcooking fish. Enjoy!
