Gather the ingredients. Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a medium baking dish.
Place salmon in the baking dish.
Mix butter and lemon juice in a small bowl, and drizzle over salmon. Season with dill, garlic powder, sea salt, and pepper.
Bake in the preheated oven until salmon is easily flaked with a fork, about 25 minutes.
Serve and enjoy!
