If you have coarse or kosher salt, use this instead of table salt. The larger grains of salt will not dissolve as quickly, leading to a more even flavor in the fish.

This is a good time to add any additional seasonings you enjoy. Try out a teaspoon of chili powder, paprika, and/or cayenne for a hotter fish, or oregano, rosemary, thyme, and/or basil for an Italian herb mixture. While you can substitute some olive oil for butter, the fat in butter is essential for keeping the fish moist and flaky.

Use a meat thermometer to ensure the inside of the fish is cooked to 165 °F (74 °C). If you’d like, you can remove the fish from the oven once it reaches 160 °F (71 °C)—the temperature will continue to climb for a few minutes, and it should reach 165 °F (74 °C).

Cook the cod with chopped vegetables, such as 1 large tomato, 1 green bell pepper, 1 yellow squash or zucchini, 1/2 cup pitted Kalamata olives, halved, and cloves garlic, all finely chopped, for a full one-pan meal. Toss the veggies with 1 tablespoon olive oil and place them around the fish, letting them cook simultaneously. [3] X Research source Chop up 1/2 cup of fresh parsley and add it to your butter mixture before applying. Melt your butter ahead of time and dip the cod in it, coating the entire thing in seasoning. You can then dip the buttered fillets in flour for a light bread coating.

This breadcrumb mixture is easily customized, as the only “essential” ingredients are the breadcrumbs and the salt. If you want new seasonings, you can’t go wrong with a teaspoon of chili powder, paprika, and/or cayenne for a hotter fish. For an herb mixture, try 1 tsp dried oregano, rosemary, thyme, and/or basil.

For a low-cal version, cut the butter and breadcrumb mixtures in half. Simply drizzle the butter on top of the fish and sprinkle your breadcrumbs only on the top of the fish. Toss 2-3 chopped tomatoes, 4 cloves of garlic, and one sliced onion with a tablespoon of olive oil and surround the fish with the vegetables when cooking for an easy side-dish to go with the fish. Substitute breadcrumbs for 1/2 cup of flour for a lighter coating on your cod. [6] X Research source
