Substitutions For Haddock
If you don’t have access to haddock (or would just prefer a different fish), substitute in another mild white fish. Try this recipe with cod, tilapia, or halibut.
Keep in mind the thickness when choosing your fish fillets though, even haddock fillets can vary in thickness a bit. It’s recommended to cook fish to an internal temperature of 145°F, which you can check with an instant read thermometer in the thickest part. A good rule of thumb is 10 minutes of baking time per inch of thickness.
How To Bake Haddock
This recipe is really simple to put together and the chopped onions and dill add a great flavor to the haddock. So so delicious.
If your fish still has the skin on it, start by removing the fish skin. Also get that oven preheating to 425°F.
Place your fish on a sheet pan lined with foil. Pour melted butter with chopped onion over the fish and sprinkle with salt and pepper. Bake until the fish is cooked through, about 10 minutes. It should be opaque and flake easily with a fork. Finally, top with fresh dill and lemon slices. It’s just that easy!
Want to switch things up? Try using fresh parsley instead of the dill. Or go for a crispy baked haddock topped with seasoned bread crumbs, like in this fish from frozen recipe. I definitely suggest lemon wedges or a squeeze of lemon juice at the end though.
