Haddock is a fish that will benefit greatly from being broiled. Since it’s a white-fleshed fish, it can dry out quite easily if you cook it for too long, especially if you’re going to use haddock fillets. You can also use this basic recipe for other 3/4-in thick, white fish.
What goes good with haddock?
This particular recipe is light and fresh, so you might want to pair it with something that’s a bit more hearty and filling for a truly satisfying dinner. Check out our delicious sweet potatoes that you can make in your air fryer while the fish is broiling in your oven.

How to defrost haddock
Defrosting haddock is easy, especially if you’re working with fillets.
If you’re prepping the ingredients the night before, just put the frozen haddock fillets on the plate and leave it in your fridge to thaw slowly overnight.
If you need to defrost the fillets quickly, place the frozen fillets in a sealed plastic bag and put the bag in a bowl of cold water. Replace the water every two hours until the fillets are completely thawed.

How do you know when haddock is cooked?
Haddock is cooked when the flesh is no longer opaque and flakes easily with a fork. Keep in mind that haddock can dry out easily so be careful that you don’t overcook your fish! It will continue to cook once off the heat.

Use a Fish Spatula to Transfer the Fish
A fish spatula (Walmart affiliate) will help you transfer the fish more easily from your serving tray to your dishes. The wide surface and thin edge of the spatula is perfect for lifting the fish without breaking it.

Broiled Haddock Recipe
Ingredients
- 4 6-oz. fresh haddock fillets
- ¾ c. Parmesan cheese shredded or freshly grated
- 4 medium tomatoes
- 2 c. fresh basil leaves
- 2 T. extra-virgin olive oil divided
- Salt and black pepper to taste
Instructions
- Preheat your oven to broil and line a large, rimmed baking tray with aluminum foil. Brush foil lightly with 1 T oil to help the fish come off the pan easily.

- Toss diced tomatoes and basil in a small bowl with remaining olive oil and season with salt and black pepper to taste. Set aside to marinate while fish cooks.
- Arrange the haddock fillets on the prepared baking sheet and brush with 1 T of olive oil. Sprinkle with Parmesan cheese, and season each filet with a dash of salt and pepper.
- Place in oven and broil for 6-8 minutes until the fish is golden-brown on top and flakes easily with a fork.
- Remove from oven and set aside.
- Spoon 1/4 of the tomato/basil onto a serving plate and nestle a filet of fish next to or on top.
- Serve hot. Garnish with a wedge of lemon, if desired.
