Pan Fried Cod in Citrus and Butter Sauce

Oven250 °F (120 °C)

Time30 minutes

Ingredients

Directions

Marinate

Lay the cod filets in a shallow pan or baking dish.
Zest 1 orange and 1 lemon and add the zest to the fish.
Squeeze the juice from the orange and lemon you just zested and add it to 1/4 cup of the olive oil.
Whisk the mixture together and pour it over the fish. Cover and let marinate for at least 30 minutes.

Cook the fish

Preheat the oven to 250 °F (120 °C).
Heat the remaining 1/4 cup of olive oil in a large oven‑safe sauté pan until hot.
Shake the excess marinate from the fish, saving it, and drop the fish into the pan.
Cook the fish over medium heat for about 4 minutes.
Flip the fish and cook the other side for about 4 minutes.
Season the fish with salt and black pepper.
Place the fish in the oven to keep warm while you make the sauce.

Make the sauce and serve

Melt the butter in a smaller pan, then add the sugar and the remaining leftover marinate from the fish.
Add the juice of the remaining two oranges to the pan.
Bring the sauce to a boil, whisking regularly until it has thickened slightly and reduced.
Add about 1/4 cup of finely shredded basil leaves to the sauce.
Taste the sauce and adjust the seasoning if necessary.
Remove the fish from the oven and pour the thickened sauce over it.
Add more basil if desired and serve the fish over rice or quinoa.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White cod filets: Forms the main protein, cooking to flaky, tender pieces when seared and kept warm.
Olive oil: Carries the citrus marinade and conducts heat for an even sear in the pan.
Orange juice: Adds acidity and sweetness that brighten the fish and form the base of the sauce.
Unsalted butter: Adds richness and helps the sauce become glossy and smooth.
Light brown sugar: Adds sweetness and caramel notes that balance the citrus acidity in the sauce.

The step that matters

Thickening the sauce. Boiling the marinade and juice reduces water and concentrates sugars and pectin, so the sauce thickens. Whisking keeps it smooth and prevents scorching on the bottom of the pan.
