Season salmon filets with salt and pepper. (If skinless, season on both sides).
Heat a skillet over medium high heat. (Or, feel free to use a grill pan if desired! For this method, I’d recommend turning the heat up a bit higher to get those nice char marks.)
Add oil to pan. Add salmon filets (skin side up, if there’s skin) and cook until golden and crisp, about 4 minutes. (Don’t move the salmon around while it’s cooking—let it sit and brown to get a nice crust!)
Carefully flip the filets and reduce heat to medium. Continue to cook to your liking, about 4-5minutes. Cook time will depend on the thickness of your filets and your preferred doneness. Cook 4 additional minutes for medium-rare, or 5+ minutes for medium-well to well-done.
Enjoy as is, or serve with your favorite sauce. (I recommend my cilantro pesto recipe!)
