Instructions

  1. Step 1: Preheat oven to 425°F. In a large bowl, toss 1 lb halved baby potatoes with 2 tbsp olive oil, 2 minced garlic cloves, 3/4 tsp salt, and 1/2 tsp black pepper until evenly coated.
  2. Step 2: Spread the potatoes on a large rimmed baking sheet in a single layer and roast for 20 minutes until golden and tender.
  3. Step 3: While potatoes roast, place 4 cod fillets on a lightly oiled baking dish. Drizzle with 2 tbsp olive oil, 2 tbsp lemon juice, 1 tsp lemon zest, 1 tsp dried oregano, 3/4 tsp salt, 1/2 tsp black pepper, and sprinkle 2 tbsp chopped fresh parsley and remaining 2 minced garlic cloves over the fish.
  4. Step 4: After the potatoes have roasted 20 minutes, add the cod to the oven and bake everything together for an additional 12-15 minutes, until the cod flakes easily with a fork and potatoes are crisp.
  5. Step 5: Serve the cod alongside the garlic roasted potatoes, garnished with extra fresh parsley if desired.
