WHY THIS RECIPE WORKS:
Who isn’t looking for more simple, crowd-pleasing meals that are perfect for any night of the week during any time of the year? This ingenious recipe delivers perfectly roasted fillets and potatoes all in one sheet pan. We roasted the cod fillets atop beds of shingled sliced spuds to give the quick-cooking fish some insulation. Slicing and microwaving starchy russets with garlic and oil before roasting jump started their cooking so that the potatoes and fish finished at the same time. To infuse the mild cod with flavor, we topped each fillet with butter, thyme sprigs, and slices of lemon, allowing the three components to gently baste and season the cod as it roasted. In the end, we were met with four elegant portions of rich, tender cod and fragrant, crisp potatoes. You can substitute haddock or halibut for the cod.
