What You’ll Need
Most of these items are likely already in your kitchen. Use fresh lemon for the best citrus punch.
- 600g Atlantic cod fillets
- 500g baby gold potatoes, halved
- 3 tablespoons olive oil
- 1 teaspoon dried oregano
- 1/2 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
- 200ml heavy cream
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 2 cloves garlic, minced
- 1 tablespoon fresh parsley, finely chopped
- 1 teaspoon fresh dill, finely chopped
Step-by-Step Directions
- Preheat the oven to 200 degrees Celsius (400 degrees Fahrenheit).
- Toss the halved baby potatoes with olive oil, dried oregano, salt, and pepper on a large rimmed baking sheet.
- Roast the potatoes in the preheated oven for 20 minutes until they begin to soften and brown.
- In a small mixing bowl, whisk together the heavy cream, lemon juice, lemon zest, minced garlic, parsley, and dill.
- Remove the baking sheet from the oven and move the potatoes to the outer edges to create space in the center.
- Place the cod fillets in the center of the baking sheet and pour the cream mixture evenly over the fish.
- Return the tray to the oven and bake for 12 to 15 minutes, or until the cod is opaque and flakes easily with a fork.
How to Serve It
Serve this directly from the pan for a rustic family style look. Plate the fish with a generous scoop of the creamy sauce. Add a side of steamed green beans or a crisp salad. A piece of crusty bread is perfect for soaking up extra sauce. This meal feels complete and balanced on its own.
Leftovers & Storage
Store any leftovers in an airtight container in the fridge. The fish stays fresh for up to two days. Reheat it gently in the oven at 300°F (150°C). This prevents the cream sauce from separating or the fish getting rubbery. I do not recommend freezing this dish because of the cream. It is best enjoyed fresh from the oven.
Make It Even Better (Pro Tips)
- Always pat the cod fillets dry with paper towels before baking.
- Do not skip the lemon zest as it provides the most flavor.
- Cut potatoes into uniform sizes so they cook evenly.
- Use a meat thermometer to check the fish reaches 145°F (63°C).
- Swap dried oregano for fresh thyme if you have it.
- Add a pinch of red pepper flakes for a tiny kick.
- Garnish with extra fresh herbs just before serving for brightness.
Easy Ways to Change It Up
- Try using salmon fillets instead of cod for a richer meal.
- Add asparagus spears to the tray during the last 10 minutes.
- Use half-and-half instead of heavy cream for a lighter version.
- Replace the dill with tarragon for a different herbal profile.
Quick Questions
Can I use frozen cod?
Yes, you can use frozen fillets for this recipe. Just make sure to thaw them completely in the fridge first. Pat them very dry before adding the sauce to the pan.
What if my potatoes aren’t soft?
If the potatoes are still hard after 20 minutes, give them more time. Every oven is a little bit different. Wait until they are fork-tender before adding the fish.
Can I use a different white fish?
Haddock or pollock work beautifully as substitutes for cod. Choose any thick white fish that flakes easily. Adjust the final bake time slightly based on the thickness.
I hope this easy one-pan dinner makes your weeknight a little brighter. It is proof that simple ingredients can taste incredible. Let me know how yours turns out!
