Baked haddock with a golden breadcrumb topping is a classic New England-style dish that turns a mild, flaky white fish into a comforting, weeknight-friendly meal. The crunchy, buttery crumb crust contrasts beautifully with the tender, moist fish, and it comes together in about 30 minutes with simple pantry ingredients. This recipe delivers a reliably crisp topping and perfectly cooked haddock every time.
Ingredients
- 1 ½ lbs (680 g) haddock fillets (or cod, see Tips)
- 1 cup (100 g) fresh breadcrumbs (from about 2 slices of bread)
- ¼ cup (30 g) grated Parmesan cheese
- 3 tbsp (45 g) unsalted butter, melted
- 2 tbsp (30 ml) olive oil
- 2 tbsp (8 g) chopped fresh parsley, plus more for garnish
- 1 clove garlic, minced
- ½ tsp lemon zest (from about ½ lemon)
- ½ tsp salt
- ¼ tsp black pepper
- Lemon wedges, for serving
Instructions
- Preheat your oven to 400°F (200°C). Lightly grease a baking dish large enough to hold the haddock in a single layer, or line a baking sheet with parchment paper.
- Pat the haddock fillets dry with paper towels. Place them in the prepared dish, skin-side down if they have skin. Season both sides lightly with salt and pepper (remember the topping also has salt).
- In a small bowl, combine the breadcrumbs, Parmesan, melted butter, olive oil, parsley, garlic, lemon zest, ½ teaspoon salt, and ¼ teaspoon pepper. Stir until the mixture is evenly moistened and resembles wet sand.
- Spoon the breadcrumb mixture over the top of each fillet, pressing gently so it adheres. It’s fine if some falls off the sides; that’s part of the charm.
- Bake for 15–20 minutes, until the topping is golden brown and the fish flakes easily with a fork. To check doneness, insert an instant-read thermometer into the thickest part of the fillet—it should read 145°F (63°C), the USDA FSIS safe minimum for fish. If the topping browns too quickly, loosely tent with foil for the last 5 minutes.
- Remove from the oven and let rest for 2–3 minutes. Sprinkle with extra parsley and serve with lemon wedges.
Tips
- Fish substitution: Cod, pollock, or hake work perfectly in place of haddock. They have a similar firm, flaky texture. Avoid thin fillets like sole, which will overcook before the topping browns.
- Fresh vs. dry breadcrumbs: Fresh breadcrumbs (from day-old bread) give a softer, more substantial crust. Panko works too—use about ¾ cup (75 g) and expect a crunchier texture. If you only have dried breadcrumbs, reduce the butter to 2 tablespoons (30 g) and the olive oil to 1 tablespoon (15 ml), as they absorb less moisture.
- Don’t overcrowd: Leave a little space between fillets so the heat circulates and the topping crisps evenly. If the fillets are very thick, you may need to add 5 minutes to the baking time.
- Check early: Ovens vary. Start checking at 15 minutes; the fish is done when it’s opaque and flakes easily. Overcooking is the most common mistake—it turns the fish dry and rubbery.
Serving Suggestions
Serve the baked haddock with a squeeze of fresh lemon juice over the top. It pairs beautifully with roasted baby potatoes or a simple rice pilaf. For vegetables, try steamed green beans, sautéed spinach, or a crisp green salad with a light vinaigrette. A side of tartar sauce or a simple lemon-butter sauce (melted butter with a little lemon juice and capers) is also lovely.
Variations
- Herb crust: Add 1 teaspoon of dried thyme or dill to the breadcrumb mixture, or swap the parsley for fresh dill.
- Spicy kick: Add ¼ teaspoon of smoked paprika or a pinch of cayenne pepper to the topping.
- Cheesy topping: Replace the Parmesan with an equal amount of sharp cheddar or Gruyère for a richer flavor.
- Panko-crusted: For a lighter, extra-crispy crust, use panko breadcrumbs and increase the olive oil to 2 tablespoons (30 ml).
Storage and Reheating
Refrigerate any leftovers in an airtight container within 2 hours of cooking. They will keep for up to 3 days. To reheat, place the fish on a baking sheet and warm in a 350°F (175°C) oven for 10–12 minutes, until heated through and the topping is crisp again. You can also use a toaster oven or air fryer at 350°F (175°C) for 5–7 minutes. Avoid the microwave—it will make the topping soggy and the fish rubbery. The USDA recommends reheating leftovers to an internal temperature of 165°F (74°C).
Frequently Asked Questions
Can I use frozen haddock? Yes, but thaw it completely in the refrigerator overnight and pat it very dry before baking. Frozen fish releases more water, so you may need to add a few minutes to the baking time.
Why is my topping not crispy? Usually it’s because the fish released too much moisture, or the topping was too wet. Make sure to pat the fish dry, and don’t overdo the butter/oil. Also, bake at a high enough temperature (400°F/200°C) and don’t cover the dish tightly.
Can I prepare this ahead of time? You can assemble the whole dish (with the topping on) up to 2 hours ahead and keep it in the refrigerator. Add 5 minutes to the baking time to account for the cold start. Alternatively, mix the breadcrumb topping and store it separately in the fridge for up to 2 days.
How do I know when the haddock is done without a thermometer? Insert a fork into the thickest part and twist gently. The fish should flake easily and look opaque all the way through. If it still looks translucent in the center, it needs more time.
Can I use this topping for other fish? Absolutely. It works well on salmon, trout, or any firm white fish. Adjust the baking time based on the thickness of the fillets.
Is haddock sustainable? Many haddock fisheries are certified sustainable, particularly those in the North Atlantic. Look for MSC certification or ask your fishmonger for advice on sustainably sourced options.
