Tips and Tricks

Below, find a collection of pro tips and tricks to help you make the best baked cod and potatoes.

  • Don’t over-boil the potatoes. Remove the potatoes from the boiling water while they are still a bit firm yet easily pierced with a fork. Since they will finish cooking in the oven, you want to make sure they still have a bit of a bite after being boiled.
  • Slice the potatoes and cod into similar-sized pieces. To promote even-cooking, slice the ingredients into similar-sized pieces. 1-inch to 2-inch pieces are recommended!
  • Remove any excess moisture from the fish. To ensure the cod gets crispy, pat the fish fillets with paper towels to remove any excess moisture before seasoning and baking.
  • Use high-quality European-style butter. All butter is not created equal. Many American brands are not churned as long as European brands, resulting in a lower butterfat content and a more bland taste.
  • Assemble the cod and potatoes in a single layer. To promote even-cooking and a crispy finish, lay the cod and potatoes in a single layer.
  • Play around with different seasonings. To make this recipe your own, feel free to play around with different seasonings. Add a couple of cracks of black pepper or red pepper flakes for a little spice or go the herby route with fresh thyme or fresh parsley. You could also sprinkle on some whole garlic cloves if that’s what you’re into.
  • Add some fresh lemon. If you love the combination of citrus and white fish, squeeze on some fresh lemon juice or grate on some lemon zest. Alternatively, you can sprinkle lemon slices over the top before baking to make for a pretty presentation.
