Preheat your oven on the high broil setting.
Lightly oil the bottom of a casserole dish and place the salmon fillet in it. Drizzle olive oil over the flesh of the salmon and use your hands to spread it over the full surface so that everything is coated. Sprinkle with sea salt.
In a small bowl, combine the paprika, garlic powder, onion powder, and coriander. Sprinkle this mixture liberally over the salmon (note: you may have leftover seasoning, and that's fine! You can use it for future salmon/chicken/steak endeavors or on vegetables).
Place the salmon on the second-to-the-top shelf of the oven and broil for 10 minutes. (6 minutes for rare salmon, and up to 15 minutes for a very thick cut of salmon). Remove from the oven and allow salmon to cool 5 minutes before serving with your favorite side dishes.
If you follow a Low-FODMAP diet, replace the onion powder and garlic powder with dried oregano and thyme.
