Lemon-Herb Cod with Crispy Garlic Potatoes
WHY THIS RECIPE WORKS:
We set out to develop a simple one-dish dinner of flaky cod and crispy roasted potatoes. For potatoes that would cook through quickly, we sliced russet potatoes thin, tossed them with oil and garlic, and shingled them into two piles in a greased baking dish. We roasted the potatoes until they were spotty brown and tender then added the cod fillets—topped with pieces of butter, sprigs of thyme, and slices of lemon—and slid it all back into the oven. After just 15 minutes more, we had a perfect dinner of moist, subtly flavored cod and crispy, garlicky potatoes. Try to purchase cod fillets that are similar in size so that they cook at the same rate. If the fillets are much thinner than 1 inch, simply fold them over to make them thicker. Halibut and haddock are good substitutes for the cod. See the sidebar that follows the recipe.
