Why You’ll Want This Tonight

• Quick and simple: Ready in about 35–45 minutes, no fancy skills required.
• Light but satisfying: Lean cod paired with creamy coconut milk gives you comfort without heaviness.

Ingredients for the Dish

• 21 oz / 600 g cod fillets
• Salt and black pepper, to taste
• 2 tbsp olive oil
• 1 medium onion, thinly sliced
• 1 tbsp freshly grated ginger
• 2 garlic cloves, crushed
• 1.2 cups / 300 ml coconut milk (full-fat is best for creaminess)
• 1 large lemon (juice and zest)

How to Bake and Finish

1. Preheat oven to 180°C (350°F).
2. Choose cod fillets of similar thickness (about 1–1.5 inches).
3. Pat the cod dry with paper towels, season both sides with salt and black pepper, and arrange fillets in a single layer in a baking dish.

4. Thinly slice the onion, grate the ginger, and crush the garlic cloves.

5. Heat olive oil in a skillet over medium heat and cook the sliced onion until soft and translucent, about 5–7 minutes.
6. Stir in the grated ginger and crushed garlic and cook until fragrant, about 30–60 seconds.
7. Pour in the coconut milk and bring to a gentle simmer.

8. Add lemon juice and zest slowly while stirring; if the sauce looks curdled, whisk vigorously to smooth it, then simmer for 1–2 minutes to blend flavors.

   

9. Pour the coconut-lemon cream sauce over the cod, spooning some over the fillets so they are partly submerged.
10. Bake until the cod flakes easily with a fork and registers 145°F (63°C) at the thickest part, about 20–25 minutes (adjust for thickness).

11. Remove the dish from the oven and let the cod rest for 1–2 minutes before serving.

    

Chef’s Tips for Success

• Pick fillets that are about the same thickness—around 1 to 1.5 inches—so they cook evenly.
• Dry the fish well before seasoning to make sure the sauce sticks and to avoid extra moisture in the baking dish.
• Use full-fat coconut milk for a creamy, luscious sauce. Light coconut milk tends to be more watery and less rich.
• When adding lemon juice, do it slowly. If the sauce curdles, whisk it briskly to bring it back to a smooth consistency.
• Use a meat thermometer if you’re unsure—145°F (63°C) at the thickest point means it’s perfectly done.
• Don’t overcook! Cod can dry out quickly, so watch it carefully once it’s in the oven.

Flavor Swaps and Add-Ins

• Try swapping cod with another mild white fish like halibut, haddock, or pollock—just adjust baking time based on thickness.
• For a creamy but dairy-free twist without the coconut flavor, try making cashew cream by blending soaked cashews with water.
• Switch up the citrus by using lime instead of lemon for a fresh, slightly different zing.
• If you want to amp up the coconut flavor, swap olive oil for coconut oil when you sauté your aromatics.
• No fresh ginger? No problem—use 1 teaspoon of ground ginger or ginger paste.

Storing and Reheating

• Leftovers keep well in an airtight container in the fridge for up to 2 days. The sauce might thicken as it chills, which is totally normal—just reheat gently before serving.
• Make the sauce a day ahead and store it in the fridge to save time on busy evenings. Warm it up gently before pouring it over fresh cod and baking.
• When reheating leftovers, microwave in short 30-second bursts until warm or place the cod in a covered dish and heat at 300°F (150°C) for 8–12 minutes. Avoid high heat to keep the fish tender and moist.

Answers to Common Questions

• Why does my coconut sauce look curdled when I add lemon juice?

  The acid in lemon juice reacts with the coconut milk, sometimes causing it to look curdled or separated. This is totally normal! Just whisk the sauce quickly or add the lemon juice slowly while stirring to keep it smooth.

• Should I use full-fat or light coconut milk?

  For the creamiest, richest sauce, I highly recommend full-fat coconut milk. Light coconut milk tends to be thinner and can result in a less creamy texture.

• Do I need to remove the skin from the cod before baking?

  No need to remove it. Leaving the skin on helps hold moisture during baking, keeping the fish tender. You can always peel it off after cooking if you don’t want to eat it.

• How can I tell when the cod is done?

  The fish should flake easily when you run a fork over it and look opaque throughout. For extra confidence, use a meat thermometer—it should read 145°F (63°C) inside at the thickest part.
