Steamed Haddock with Garlic

Preheat oven to 350 degrees F (175 degrees C).

Place haddock fillets on an 18x18-inch piece of aluminum foil; top with butter.

Sprinkle onion, garlic, dill, and pepper over butter and haddock.

Squeeze juice from 1/2 lemon evenly on top.

Lift up bottom and top ends of the aluminum foil towards the center; fold together to 1 inch above the haddock.

Flatten short ends of the aluminum foil; fold over to within 1 inch of the sides of the haddock.

Place foil package on a baking sheet.

Bake in the preheated oven until haddock flakes easily with a fish, about 45 minutes.

Let sit, about 5 minutes.

Open ends of the packet carefully; squeeze juice from the remaining 1/2 lemon on top.
