Ingredients
  

  • Cod fillets (about 1.5 to 2 pounds total, skinless, 4 pieces)
  • Lemons (2, for juice and zest)
  • Fresh herbs (mix of parsley and dill, or parsley and thyme)
  • Garlic (3–4 cloves)
  • Olive oil
  • Sea salt and black pepper
  • Smoked paprika or sweet paprika (optional, for color and warmth)
  • Red pepper flakes (optional, for a little heat)
  • Veggies to roast (choose 3–4):
  • Baby potatoes or fingerlings
  • Carrots
  • Broccoli or broccolini
  • Cherry tomatoes
  • Red onion
  • Zucchini or yellow squash
  • Bell peppers
  • Asparagus
  • Optional finishers: capers, butter, or a drizzle of honey

Method
 

  1. Preheat and prep. Heat your oven to 425°F (220°C). Line two sheet pans with parchment for easy cleanup. Pat the cod dry with paper towels so it sears and flakes nicely.
  2. Make the lemon-herb mix. In a small bowl, combine the zest of 1 lemon, juice of 1 lemon, 2–3 tablespoons olive oil, 2 minced garlic cloves, 2 tablespoons chopped parsley, 1 tablespoon chopped dill (or thyme), 1/2 teaspoon salt, and several grinds of pepper. Add a pinch of red pepper flakes if you like heat.
  3. Season the fish. Place the cod on a plate or small tray. Spoon over half the lemon-herb mix and let it sit while you prep the vegetables, about 10 minutes. This quick marination adds brightness without turning the fish mushy.
  4. Prep the veggies. Cut potatoes into bite-size pieces, slice carrots on a bias, and break broccoli into medium florets. Halve cherry tomatoes and slice onion into wedges. Aim for similar sizes so they cook evenly.
  5. Toss and roast the hearty veg first. On the first sheet pan, toss potatoes and carrots with 1–2 tablespoons olive oil, 1 minced garlic clove, 1/2 teaspoon salt, pepper, and a dusting of smoked paprika. Spread out. Roast 12–15 minutes to give them a head start.
  6. Add quicker-cooking veg. Pull the pan out. Add broccoli and red onion (and bell peppers or zucchini if using). Drizzle with a bit more oil, season, and toss. Return to the oven for another 10 minutes.
  7. Roast the cod. While the veggies continue, place the cod on the second sheet pan. Spoon on the remaining lemon-herb mix. Roast for 8–12 minutes, depending on thickness, until the fish flakes easily and is opaque. Thinner fillets need less time; thicker ones may need a minute or two more.
  8. Finish the veggies. If using cherry tomatoes or asparagus, add them to the vegetable pan for the last 6–8 minutes so they stay juicy and bright. Everything should be tender with caramelized edges.
  9. Optional pan sauce. For a richer finish, melt 1 tablespoon butter in a small pan with a spoonful of capers and a squeeze of lemon. Warm gently and spoon over the cod.
  10. Serve. Plate the roasted vegetables first, top with a piece of cod, and garnish with extra herbs and lemon wedges. Taste and adjust salt and lemon at the table for a clean, punchy finish.
