Preheat oven to 400 F. Place a wire rack onto a large baking sheet.
In a small bowl, combine olive oil, garlic salt, dried dill, and black pepper.
Using gloved hands, spread olive oil mixture all over all sides of the salmon filets. Top each filet with fresh dill.
Place seasoned filets onto wire rack on baking sheet.
Top each filet with lemon slices.
Bake uncovered for 7-9 minutes.
Notes
You can purchase salmon filets individually or buy a whole center cut salmon and cut them yourself. Be sure to cut into filets while the fish is raw.
Store leftover dill salmon in an air-tight container kept in the refrigerator for 3-4 days.
For reheating, it's best to do so at a low temperature in the oven. I would recommend preheating the oven to 300F, placing the filets on a baking sheet, and reheating for around 10-15 minutes or until warmed through. You don't want to rush the process of reheating salmon as it can dry out rather quickly.
