Ingredients
Method
- Preheat and prep: Heat the oven to 425°F (220°C). Line a large sheet pan with parchment for easy cleanup. Pat the cod dry with paper towels and set aside.
- Toss the veggies: In a large bowl, combine potatoes, bell pepper, red onion, and broccoli. Drizzle with 2 tablespoons olive oil. Add 1/2 teaspoon salt, 1/4 teaspoon pepper, paprika, and oregano. Toss to coat well.
- Start the roast: Spread the veggies in a single layer on the sheet pan. Roast for 12 minutes to give the potatoes a head start.
- Make the lemon-garlic mix: In a small bowl, stir together the minced garlic, lemon zest, 2 tablespoons lemon juice, remaining 1 tablespoon olive oil, butter (melted), Dijon, and honey if using. Season with a pinch of salt and pepper. Taste and adjust—aim for bright and savory with a gentle garlicky kick.
- Season the cod: Sprinkle the fillets with 1/2 teaspoon salt and 1/4 teaspoon pepper. Spoon 1–2 teaspoons of the lemon-garlic mixture over each fillet and rub lightly to coat.
- Add cod to the pan: Pull the pan of veggies from the oven. Push the veggies to the edges to create four spaces. Nestle the cod in the open spots. Spoon a little more of the lemon-garlic mixture over the veggies.
- Roast to finish: Return the pan to the oven and roast 8–12 minutes, depending on thickness. Cod is done when it flakes easily and turns opaque. Aim for an internal temperature of 130–135°F (54–57°C) for moist, just-cooked fish.
- Final touch: Drizzle the remaining lemon-garlic mixture over the cod and veggies. Sprinkle with chopped parsley. Add extra lemon wedges on the side.
- Serve: Plate the cod with a mound of veggies. Spoon any pan juices over the top. Taste and add a last pinch of salt or squeeze of lemon if needed.

Spoon any pan juices over the top. Taste and add a last pinch of salt or squeeze of lemon if needed.
Keeping It Fresh
- Storage: Store leftovers in an airtight container in the fridge for up to 2 days. Fish is most enjoyable the first day, but this one reheats gently.
- Reheating: Warm in a 300°F (150°C) oven for 8–10 minutes, or microwave in short bursts at 50% power.
Don’t overheat or the cod will dry out.
- Make-ahead tips: Chop veggies and mix the lemon-garlic sauce up to 24 hours ahead. Keep the sauce chilled. Pat fish dry and season right before cooking.
- Freezing: Not ideal once cooked.
If you must, freeze the veggies separately. Cooked cod gets mealy after thawing.
Why This is Good for You
- Lean protein: Cod is low in fat and high in protein to keep you full without heaviness.
- Omega support: While cod isn’t as rich in omega-3s as salmon, it still offers some, plus key nutrients like B vitamins and selenium.
- Fiber and antioxidants: Broccoli, peppers, and onions bring fiber, vitamin C, and colorful plant compounds that support overall health.
- Healthy fats: Olive oil and a modest amount of butter make a satisfying sauce without going overboard.
- Lower sodium, big flavor: Bright lemon and garlic let you season smartly without heavy salt.
Common Mistakes to Avoid
- Skipping the pat-dry step: Wet fish steams instead of roasting. Patting the cod dry helps it cook evenly and absorb flavor.
- Overcooking: Cod cooks fast.
Start checking at 8 minutes. Pull it as soon as it flakes.
- Crowding the pan: Give the veggies space. If the pan is jammed, they steam and turn soggy.
- Adding the cod too early: Potatoes need a head start.
If everything goes in at once, the fish overcooks before the veggies are tender.
- Forgetting to taste the sauce: Lemon sizes vary. Taste and tweak the sauce before it hits the pan.
Alternatives
- Different fish: Swap cod for haddock, pollock, or halibut. For thinner fillets like tilapia, cut roasting time by a few minutes.
- Veggie swaps: Try asparagus, green beans, zucchini, cherry tomatoes, or carrots.
Adjust timing—soft veggies need less time, carrots a bit more.
- Dairy-free: Use all olive oil instead of butter. Add a little extra Dijon for richness.
- Spice twist: Add red pepper flakes for heat, or swap oregano for thyme. A pinch of cumin with paprika adds warmth.
- Sheet pan to skillet: Sear the cod in a hot skillet with oil for 2 minutes per side, then finish in the oven with the veggies if you prefer a light crust.
- Grain add-on: Serve over quinoa, couscous, or brown rice to stretch the meal and soak up the sauce.
FAQ
How do I know when cod is done?
Cod turns opaque and flakes easily when you press it with a fork.
For accuracy, use a thermometer and aim for 130–135°F (54–57°C). Pull it a touch early; carryover heat will finish the job.
Can I use frozen cod?
Yes. Thaw it fully in the fridge overnight or in a sealed bag under cold water.
Pat very dry before seasoning so it roasts, not steams.
What if I don’t like broccoli?
Swap in asparagus, green beans, or zucchini. Add these when you add the cod, since they cook faster than potatoes.
Is the honey necessary?
No. It simply softens the sharpness of lemon and garlic.
If your lemon is mild, skip it. If your sauce tastes too tart, a small drizzle helps balance it.
Can I make this on the grill?
Yes. Use a grill-safe pan or foil packet for the veggies.
Grill the cod on oiled grates or in a fish basket over medium heat for 3–4 minutes per side, brushing with the lemon-garlic mixture.
What wines pair well with this?
Try a crisp Sauvignon Blanc, Pinot Grigio, or a light unoaked Chardonnay. If you prefer beer, a pilsner or a citrusy wheat beer works well.
How do I prevent the fish from sticking?
Use parchment on the sheet pan or lightly oil the surface. Also, don’t move the cod around as it cooks.
Let it roast undisturbed.
