Tips for this recipe
- Prep everything first This moves fast once the fish goes under the broiler so have crumbs and butter ready.
- Dry the haddock well Moisture prevents browning and leads to steaming instead of a crisp top.
- Let the butter brown gently Medium heat is key so it turns nutty not burnt.
- Keep the crumb layer light A thin, even coating stays crisp while thick layers go soggy.
- Position the rack correctly Set it about 6 inches from the broiler for strong but controlled heat.
- Watch it closely Buttered crumbs can burn quickly under broil so do not walk away.
- Cook to temperature Pull at 125 to 130°F for juicy, flaky fish with clean separation.
Broiled Haddock with Brown Butter Breadcrumbs
Ingredients
Equipment
Method
- Pat the haddock fillets very dry with paper towels. Lightly salt them and place in the fridge for 20 to 30 minutes for a quick dry brine.
- Mince the garlic, chop the parsley, and zest the lemon.
- Preheat the broiler on high and position the rack about 6 inches from the heat source.
- In a small saucepan over medium heat, melt the butter. Let it foam and cook until golden brown with a nutty aroma. Remove immediately from heat.
- In a bowl, combine the breadcrumbs, garlic, lemon zest, parsley, and a pinch of salt. Add the brown butter and mix until evenly coated.
- Pat the fish dry again after dry brining. Lightly brush the tops with Dijon mustard.
- Place the haddock on a lightly oiled sheet pan and season with pepper. Press a thin, even layer of breadcrumbs onto each fillet. Drizzle lightly with olive oil.
- Broil on high for 6 to 9 minutes until the topping is golden and crisp and the fish reaches 125 to 130°F internally. Watch closely to prevent burning.
- Rest for 2 minutes. Finish with fresh lemon juice and serve immediately.

Build a balanced plate with contrast.
- Charred lemon broccolini for bitterness and brightness
- Crispy smashed potatoes with garlic oil for crunch and richness
- Fennel and apple slaw for fresh acid and texture
Why this works
This dish hits all the right balance points.
- Fat: brown butter and olive oil add richness
- Acid: lemon zest and fresh juice cut through the fat
- Sweet: browned butter solids bring subtle nutty sweetness
- Heat: broiler intensity creates crisp edges and energy
- Fresh: parsley and citrus lift the whole dish
High broiler heat crisps the breadcrumb layer quickly while keeping the haddock moist. The thin topping ensures crunch without trapping steam, and the acid finish keeps the richness from feeling heavy.
Pro tips
- Use even thickness fillets for consistent cooking
- If crumbs brown too fast, lower the rack slightly
- A metal pan gives better browning than glass
- Finish with lemon at the last second for maximum impact
How to serve broiled haddock with brown butter breadcrumbs
Serve immediately while the topping is crisp and the fish is still juicy.
