How to Make Baked Haddock with Lemon Butter and Herbs
Follow these simple steps to prepare perfectly baked haddock with a glossy lemon butter sauce.
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a medium-sized baking dish with a small amount of butter or cooking oil.
Choose a dish large enough to hold all four haddock fillets in a single layer.
Step 2: Prepare the Haddock Fillets
Remove the haddock fillets from their packaging.
Check for any remaining pin bones and remove them if necessary.
Pat the fish thoroughly dry with paper towels.
Removing excess moisture helps the seasonings adhere and prevents unnecessary water from collecting in the baking dish.
Step 3: Arrange the Fish
Place the haddock fillets in the prepared baking dish.
Arrange them in a single layer with a little space between each piece.
Avoid overlapping the fillets so they cook evenly.
Step 4: Season the Haddock
Sprinkle the fillets evenly with salt and freshly ground black pepper.
Season both sides lightly if desired.
Haddock has a delicate flavor, so simple seasoning allows its natural sweetness to shine.
Step 5: Add the Butter
Cut the butter into small, evenly sized pats.
Place the butter pieces directly on top of the haddock fillets.
Distribute the butter evenly so every fillet receives some.
As the fish bakes, the butter will melt and combine with the natural cooking juices.
Step 6: Add Fresh Parsley
Sprinkle the chopped parsley over the raw fish.
Reserve a little parsley for garnishing after baking.
The fresh herbs add color and a light, aromatic flavor.
Step 7: Bake the Haddock
Transfer the baking dish to the preheated oven.
Bake at 400°F (200°C) for approximately 12–14 minutes, depending on the thickness of the fillets.
The haddock should become opaque, white, and flaky.
For food safety, the thickest part of the fish should reach an internal temperature of 145°F (63°C).
Thicker fillets may require a few additional minutes.
Step 8: Check for Doneness
Carefully remove the baking dish from the oven.
Insert a fork gently into the thickest part of a fillet.
The fish should separate easily into tender white flakes.
Avoid overcooking, as haddock can become dry when exposed to excessive heat.
Step 9: Add Fresh Lemon Juice
Squeeze the juice of one fresh lemon over the hot baked haddock.
Allow the lemon juice to mix naturally with the melted butter in the baking dish.
The citrus brightens the flavor and balances the richness of the butter.
Step 10: Spoon Over the Lemon Butter Sauce
Tilt the baking dish slightly to collect the melted butter and lemon juices.
Using a spoon, drizzle the warm sauce generously over each fillet.
Make sure every piece receives a coating of the glossy lemon butter.
Step 11: Garnish the Fish
Sprinkle the remaining chopped parsley over the baked haddock.
Add a little freshly cracked black pepper if desired.
Arrange fresh lemon wedges around the fish.
Step 12: Plate and Serve
Carefully lift each haddock fillet using a wide spatula.
Transfer the fish to individual serving plates.
Spoon any remaining lemon butter sauce over the fillets.
Serve immediately with your favorite side dishes.
