Preheat oven to 375℉. Take out a baking dish large enough to hold your fish.
Prepare salmon. If needed, cut salmon so that it will fit into your baking dish. Drizzle with a small amount of olive oil. Season with salt, pepper, and salmon seasoning. Sprinkle dill over fish and top with slices of lemon.
Arrange salmon into one layer in the baking dish and place in the oven.
Bake salmon for 15-20 minutes until the fish flakes easily with a fork.
